Doctor find out solutions to manage media use by kids

In an age when exposure to TV, smartphones, computers, tablets, and all forms of social media play a dominant role in the lives of American kids and teens, many families have very few rules in place to manage their children's media use. But for their well-being, that should change, the nation's largest group of children's physicians advises.
In a newly revised policy statement released today, the American Academy of Pediatrics recommends that parents make a media use plan for their families that takes into account not only the quantity, but the quality and location of media used, and includes mealtime and bedtime curfews for media devices. It also encourages keeping all screen media (TVs, computers, tablets, etc.) out of kids' bedrooms.
The group reiterates its recommendation to limit the amount of total entertainment screen time to less than two hours a day and to discourage all screen media exposure for children under age 2.
A new, nationally representative survey from the nonprofit advocacy group Common Sense Media, also out today, shows 72% of kids ages 8 and under have used a mobile device for some type of media activity such as playing games, watching videos or using apps, up from 38% just two years ago. And 17% of these young children use a mobile device on a daily basis.
“We are worried that a lot of parents are clueless about their kids' media use and how to manage it appropriately,” says Victor Strasburger, a professor of pediatrics at the University of New Mexico and co-author of the AAP policy statement, released at the group's national conference in Orlando, Fla.
They are “spending more time with media than they are in school. They are spending more time with media than in any activity other than sleeping. You could make the argument that media have taken over the primary role of teaching kids from schools and parents in many cases,” says Strasburger.
Parents, together with pediatricians, schools, research organizations, the entertainment and advertising industries and government, need to work together to do more to address this issue, he says. He adds that the federal government has not written a comprehensive report on children and the media since 1982, before the widespread use of the Internet and cellphones.
According to findings cited in the policy statement:
• The average 8- to 10-year-old spends nearly eight hours a day with a variety of media; older children and teens spend more than 11 hours a day.
• The presence of a television set in a child's bedroom increases TV viewing even more, and 71% of children and teens report having a TV in their bedroom; 50% have a console video game player in their room.
• Nearly all children and teens (84%) are on-line; about 75% of 12- to 17-year-olds have a cellphone, up from 45% in 2004; 88% use text messaging.
Last updated five years ago, the policy statement considered a wealth of new research. It says the pediatrics group “continues to be concerned by evidence about the potential harmful effects of media messages and images.”
Excessive media use has been associated with obesity, lack of sleep, school problems, aggression and other behavior issues, the statement says.
But it adds that “important positive and pro-social effects of media should also be recognized.” It specifies that media can help children of all ages learn important academic material, and can also help “teach empathy, racial and ethnic tolerance, and a whole range of interpersonal skills.”
“Media can be good or bad,” says Strasburger. “There's some extraordinarily good media out there. It's a matter of finding the right stuff for the right aged child or teen and limiting access to inappropriate media.”
But parents need to recognize that their children are “facing a tsunami of media,” he says.
The onslaught of new digital devices to deliver that media makes the challenge of monitoring your children's “media diet” harder than ever, says Jim Steyer, CEO of Common Sense Media. Not only is there more of it, but “because these devices are mobile, screen time moves with them from room to room. It's not as easy to monitor use.”
Among other recommendations in the revised policy statement:
For Parents:
• Model effective media use to help children learn to be selective and healthy in what they consume. Take an active role in children's media education by co-viewing TV, movies and videos with them and discuss important family values.
• Monitor what media your children are using and accessing, including any websites they are visiting and social media sites they may be using
For pediatricians:
• At every well-child visit, ask how much time the child is spending with media and if there is a TV or Internet-connected device in the child's bedroom.
• Take a more detailed media history with children or teens at risk for obesity, aggression, tobacco or substance use, or school problems.

How to Make Your Computer Run Faster

Have you noticed that your computer runs slower than before? Or just slowly in general? Try these strategies to make your Windows or Mac computer run faster.


Steps :

Windows

1-Check your hard disk space. As a rule, you want to keep at least 15% of the hard disk space free to keep the computer running smoothly. Simply go to My Computer, right-click on Hard Drive, and go to Properties. There you'll see a pie chart of your free versus used space. If it’s mostly full, you'll want to start by removing unnecessary programs and files; it it’s not, you probably want to tackle the actual way your computer operates.

2-Remove any programs you do not use. Go to Control Panel > Add or Remove Programs (or Uninstall a Program, depending on your operating system) to find a master list of programs installed on your computer. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you some research.
It may help to see how often you use the program. If you right-click one of the column titles above your program list (ex. Name, Publisher, Size, Installed On, etc.), you should be able to add additional characteristics by which to judge your programs. For example, find Last Used On on the list of options and check it; a column displaying the last time you used each program will now appear and can also be used to sort your programs. Some programs will not have been used in years and may be candidates for deletion.
When in doubt, don't remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.
Don't forget to empty your recycling bin.

3-Prevent unnecessary programs from starting when the computer boots. The more programs try to run while your computer initializes, the slower everything will be. Revise your startup programs by altering your system configuration via MSConfig.

4-Install an anti-virus program, spyware scanner, and an anti-malware. The fewer bugs, viruses, and bits of adware your computer has to manage, the more time it will have to devote to other processes. While you're at it, make a point of keeping Windows up-to-date; not only will this keep Windows itself in better shape, but some viruses ride in on Windows updates that are downloaded way after the fact (and therefore not monitored as closely).

5-Run a Disk Cleanup. This can clean up hundreds of megabytes of temporary files – sometimes even gigabytes (if you have Windows XP, Vista, or 7). It will also open a window in which you can chose what to delete. Go to My Computer, right-click the Hard Drive and select Properties, and then click Disc Cleanup (within the General tab). Check all the boxes except for the game files and setup files.

6-Run a Disk Defragment. This will reconfigure the way the hard drive stores information for maximum efficiency. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Defragment Now.

7-Check for any disk errors. These will also slow your computer down. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Check Now under the Error-Checking area. When the dialogue box opens, check both boxes.
If you get a window saying that Windows can't check the disk while it's in use, click on Schedule Disk Check and then OK. It will run on your next reboot.

8-Turn off indexing. Go to My Computer, right-click the Hard Drive and select Properties, then unclick the box indicating that the drive should be indexed. Don't do this if you actually use any of the Windows Search functionality. The background indexing is what makes those searches fast and Windows is already very good about not getting in your way to do indexing while you're trying to do something else.

9-Clear your Prefetch folder. Windows saves a file of the program you are using to make it start up faster. 
After years of use, this folder gets stuffed with irrelevant programs.
Open Notepad and type:
del C:\Windows\Prefetch\*.* /Q
Rundll32.exe advapi32.dll,ProcessIdleTasks
(Copy and paste this text to ensure you don’t make any mistakes.)
Save as faster.bat (the .bat extension will run it as a batch file).
Run it! Simply double-click the file to initialize. In a few moments, the command prompt will disappear and your programs should run more smoothly.

10-Change Prefetch Parameters. This a dangerous task to complete unless you follow these steps exactly. If you're not sure about anything, don’t continue.
Go to Start > Run and type regedit to initialize the registry editor.
Go to HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>Session Manager>Memory Management>Prefetch Parameters to access the parameters.
Double-click EnablePrefetcher. Once the new window pops up, there should be a small, editable text box with the number 3 in it. (Windows allows 4 options: 0, 1, 2 and 3.) 3, the default, fetches everything.
Change this to 2. Your PC will boot a lot faster and your PC performance shouldn't be affected.
Click OK and then close regedit.

11-Add RAM to your computer. To see if you need more RAM, initialize the Windows Task Manager by pressing CTRL+ALT+DELETE. Under the Performance tab, find the area devoted to Physical Memory. If the Free amount hovers around zero but the computer is still slow, you may need to take your computer in to add RAM or even add more RAM yourself.

12-Restart your computer. The computer usually needs to reboot to implement changes.

13-Defragment your hard drive. This should make the system boot faster

14-Remove gadgets you don't use. All gadgets that are running slow down your computer.

15-Log off the users who do not want the computer. Switch user your account then if you see that many users are logged in, log them off.

Macintosh


1-Check your hard disk space. As a rule, you want to keep around 30% of the hard disk space free to keep things running smoothly. Simply right-click the Hard Drive icon on your desktop and go to Get Info.

2-Uninstall unnecessary programs. You can either uninstall them manually or download a program to help you sort and delete them. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you some research.
When in doubt, don't remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.

3-Delete files you don't need. Unless you have very little storage space on your computer or simply have an abundance of unnecessary documents, deleting small files won't make much of an impact on your computer’s overall function. However, any large files like movies you never watch, photos you don't need, or songs you never listen to can really gum up the works and should definitely be removed.
Don't forget to empty your trash bin.

4-Prevent unnecessary programs from starting when the Mac boots. The more programs try to run while your computer initializes, the slower everything will be. Go to System > Preferences > Accounts > Login Items. Select any items you don’t need and click the minus (-) sign to remove them.

5-Repair the disk. Go to Applications > Utilities > Run Disk Utility to repair both the disk and the disk permissions. It’s a good idea to run this once a month or at least once every few months.

6-Remove unnecessary dashboard widgets. Even if you don’t have the dashboard activated, these widgets can eat up RAM by running background updates while you try to do other things.
If you have OS X 10.4.2 or later, simply use the Widget Manager: go to the Dashboard and open the Widget Bar by clicking the plus (+) sign; click Manage Widgets and then either deselect widgets to disable them or, if they’re third-party widgets, remove them completely by pressing the red delete button, which is a circle with a line through it, and click OK to confirm.

7-If you use Mac OS X, download a free program called Monolingual. With OS X, much of your computer’s hard disk is devoted to virtual memory and gets eaten up by language-availability software. Monolingual will allow you to remove languages you don’t use on in order to free up space.

" Warnings "


Never delete system32 files on Windows! These are critical to running the OS correctly and will break your computer.
Do not delete "shared" files! Sometimes, a program you don’t want shares files with programs you do want, making those files unsuitable for deletion. Deleting the incorrect shared file can have wide-ranging consequences.

Facebook tries to control its bug problem and leaking info of 6 million users

This afternoon, Facebook has made one of those announcements a company never really wants to have to make: they’ve had a rather unfortunate bug problem. The big problem here was, as Facebook notes, that their most recent method for recommending friends to new users also contained contact information of users – this including information added to Facebook by the users, mind you, nothing deeper than that.
This sort of thing doesn’t necessarily affect the everyday Facebook citizen, and it’s not as if you’ll be needing to change your address or credit card number any time soon (unless you store those sorts of things in your Facebook account, for whatever reason). Instead this breach was discovered by the Facebook security team and fixed the situation by disabling their “download-your-information” tool.
“We’ve concluded that approximately 6 million Facebook users had email addresses or telephone numbers shared. There were other email addresses or telephone numbers included in the downloads, but they were not connected to any Facebook users or even names of individuals. For almost all of the email addresses or telephone numbers impacted, each individual email address or telephone number was only included in a download once or twice. This means, in almost all cases, an email address or telephone number was only exposed to one person. Additionally, no other types of personal or financial information were included and only people on Facebook – not developers or advertisers – have access to the DYI tool.” – Facebook
So no developers and no advertising agencies were able to see this information, but basically any Facebook user could. Does that keep your worries at bay?
Note also that the DYI tool was turned back on no long after it’d been shut down for a short period. No worries, continue with the downloading!
“After review and confirmation of the bug by our security team, we immediately disabled the DYI tool to fix the problem and were able to turn the tool back on the next day once we were satisfied that the problem had been fixed.” -Facebook
Facebook’s message includes a note that suggests that they are “in the process of notifying affected users via email.” They’ve also been clear that the user that found the security breach made the report to their White Hat program which in turn paid out a “bug bounty” as a reward. Remember that kids – find the breaks in the internet and ye shall be handsomely rewarded!

Motorola Razr HD review ( price , specification ,release date , features , problems, advantages, disadvantages)



Motorola's Razr HD smartphone has been out in the US for a few months and now it's arrived in the UK. Here's our Motorola Razr HD hands-on review.



Motorola's Razr HD smartphone has been out in the US for a few months and now it's arrived in the UK. Here's our Motorola Razr HD hands-on review.

We spent some time with the Razr HD (XT925) at this year's Mobile World Congress where we didn't exactly have to fight crowds to see the handset like the other vendors' stands at the show. See also: Group test: What's the best Android smartphone?

Like other recent Razr devices, Motorola has opted for something of an alternative design. The Razr HD looks like a lot of smartphones from the front with a glossy black finish but has a fascinating back.

Once again Motorola has used Kevlar as a material and this time covers the entirety of the handset's back and wraps right round to the aluminium which runs around the edge. In our opinion, it simply looks awesome and gives the premium feel you want from a smartphone.

Sadly, the Kevlar rear cover doesn't make the Motorola Razr HD bullet proof. However, the combination of it along with the alumium frame and Gorilla Glass makes the Razd HD a hardy handset. You certainly won't need to run out to buy a case or a cover for it.

In the UK, the Razr HD ships with Androud 4.1 Jelly Bean. Being owned by Google, the Motorola interface is largely vanilla Android but has its own style.

With a 1.5GHz dual-core processor, 1GB of RAM, 4.7in HD screen and an 8Mp rear camera, the Razr HD is Motorola's flagship smartphone. However, this isn't going to compete with the flagship devices of rival vendors very well.

Don't get us wrong, the Razr HD is a lovely phone. The screen looks fantastic with a 720×1280 resolution, even under the bright MWC lights, and the performance seemed decent enough to us. The issue is that there are more exciting smartphones on the market already and more are on the way.

If Motorola had launched the Razr HD in the UK last year then we would have been singing its praises. But, as it stands, it has to compete, in the Android market only, the Sony Xperia Z, HTC One and incoming Samsung Galaxy S4.

You might be thinking the Razr HD is likely to be cheaper than these rival devices, and it is. Clove and Expansys have the device for around £400 SIM-free which is a saving of at least £100. However, the Google Nexus 4 costs just £239 so the Razr HD sits in a strange a lonely position in the market.

The Razr HD does have 4G LTE built-in which is an advance over the Nexus 4, certainly. But consider that the HTC One SV costs about £250 and the Motorola handset looks less appealing.

If the Razr HD had a huge 3300mAh battery like the Razr Maxx, it would be a great reason to choose it, but it doesn't. It has a reasonable 2500mAh battery which coupled with a dual-core processor could produce a good battery life but it's no major selling point.

It's truly a shame but it's a case of Motorola bringing the Razr HD across the Atlantic too late for it to be a major contender. Every way you look at the smartphone, there is a better rival to be had for both more and less money.

Google Nexus 10 vs Apple iPad 4 tablet comparison review



Apple's fourth generation iPad is under fire from Google's Nexus 10. Read our Google Nexus 10 vs iPad 4 tablet comparison review to find out more.

The latest challenger to Apple's iPad has arrived in the form of Google's Nexus 10, made by Samsung. Updated on 28/01/13.

Unlike the Nexus 7, Nexus 10 is a direct competitor with the iPad and deserves one of our comparison reviews. We've spent a good deal of time testing both devices.

Google will be hoping to outdo the iPad with the Nexus 10 so here's how the two tablet heavyweights stand up to each other.

See also: Google Nexus 10 preview.

See also: iPad 4 review.

Google Nexus 10 vs Apple iPad 4: Price

After the budget friendly price of the Google Nexus 7, it's no surprise that the Nexus 10 is cheaper than the iPad. The Nexus 10 starts at £319 for the 16GB model while the equivalent iPad costs £80 more at £399.

The price gap is slightly bigger for the 32GB models – a gap of £90 with the Nexus 10 at £389 and the iPad at £479.

Google Nexus 10 vs Apple iPad 4: Dimensions

The two tablets are similar in their weights and measurements. The Nexus 10 is 178 x 264mm compared to 186 x 241mm; however it is thinner at 8.9mm against 9.4mm.

If weight is important to you, and it probably is, the Nexus 10 is the lighter tablet. It weighs 603g while the iPad tips the scales at 652g.

Google Nexus 10 vs Apple iPad 4: Screen

Both these tablets offer large screens. The iPad's still the classic Apple 9.7in but the Nexus 10's is marginally bigger at 10.1in. Since its third generation, the iPad uses a 2048 x 1536 Retina quality resolution. However Google has trumped this with 2560 x 1600.

When you crunch the numbers the iPad's display is impressively detailed with a pixel density of 264ppi. The Nexus 10 beats the Retina quality, though, with a whopping 300ppi.

Google Nexus 10 vs Apple iPad 4: Processor and memory

With high res displays, the processor is an important element here. The iPad 4 has an Apple A6X dual-core processor with quad-core graphics. Our benchmarking app tells us that it's clocked at 1.39GHz and the test results were impressive so check out our review for more details.

Google has gone for a similar setup with an ARM Cortex A-15 1.7GHz dual-core processor and a Mali T604 GPU (up to quad-core). We haven't had the Nexus 10 in yet but look out for our review for benchmarks. On the memory side of things the Nexus 10 has twice that of the iPad 4 at 2GB.

In the GeekBench 2 test the Nexus 10 defeated the iPad 4 with a score of 2505 against 1769. However, the iPad 4 beat the Nexus 10 in our other two benchmarks.

The iPad 4 managed 854ms in the SunSpider JavaScript test while the Nexus 10 recorded a time of 1329ms.

In terms of graphics, the Nexus 10 achieved 27fps in GLBenchmark and iPad 4 reached 39fps.

Google Nexus 10 vs Apple iPad 4: Storage

Sticking with tradition, the fourth generation iPad comes in three storage capacities: 16GB, 32GB and 64GB with no expansion available via a card slot. Google has opted for just 16GB and 32GB models, also without a microSD card slot.

Google Nexus 10 vs Apple iPad 4: Cameras

On the photography side of things the Nexus 10 and iPad 4 have a similar setup. Both have a 5Mp rear facing camera and front facing webcams. The Nexus 10 has a slightly higher rating for the front facing camera at 1.9Mp compare to 1.2Mp.

Google Nexus 10 vs Apple iPad 4: Connectivity

Connectivity on the Nexus 10 consists of 802.11b/g/n dual-band Wi-Fi, Bluetooth, GPS, near-field communications (NFC). Physical ports consist of microUSB, Micro-HDMI, 3.5mm headphone jack and a magnetic 'Pogo' pin charger.

Apple has fitted the iPad with 802.11a/b/g/n dual-band Wi-Fi and Bluetooth 4.0. Physical ports consist of the usual 3.5mm headphone jack and Apple's Lightning connector.

A big difference is that the iPad comes in a Wi-Fi + Cellular data model which supports 4G LTE connectivity in the UK.

Google Nexus 10 vs Apple iPad 4: Software

Software is an area where these tablets distinctly vary. The iPad runs on Apple's own iOS and the Nexus 10 tablet runs Google's latest version of Android, 4.2 Jelly Bean.

Google Nexus 10 vs Apple iPad 4: Battery

The iPad 4 has a 42.5Wh rated battery compared to 33.3Wh on the Nexus 10. Apple promises the usual 10 hour battery life when browsing the web over Wi-Fi. Although Google hasn't specified a battery life, The Telegraph reports a slightly lower figure of nine hours.

PayPal launches a preview of its updated design

PayPal has had the same design for quite some time, and it is, shall we say, a tad dated. That will be coming to an end in the relatively near future, with the company rolling out a preview of its updated design, complete with information about the layout and how it will benefit users. Check out its features and some screenshots after the jump.
The updated design, which you can see in the image above, is very Web 2.0-ish, with a streamlined, easier to digest interface that categorizes things in a logical, simple way. Bits of information are displayed in their own sections right on the main account screen, including notifications, recent activity, and balance.
Unlike the current design, which requires hunting through tabs and menus, the new design features drop-menus with relevant items, such as coupons, banking information and cards, and credit. The three main functions – Account Summary, Activity, and Settings – are located as tabs in the upper menu, which toggles the screen between the three categories.
Performing the most common tasks done on PayPal is also streamlined in the new layout via shortcuts on the right-hand side of the account screen. Shortcuts are available for requesting money, sending money, adding money, and withdrawing money. There’s no mention of when the new design will go into effect, but the curious can check it out here.

Nokia Lumia 620 review ( price , specification ,release date , features , problems, advantages, disadvantages)



The Lumia 620 is Nokia's most affordable Windows Phone 8 device yet. Alas, it's a device that might never make an appearance in the US, due to its very attractive pricing of (£150, or around $236), unless American carriers are willing to give a rebate from the outset. But it's a surprisingly attractive Lumia — in fact it's hard to put it in the same category as Nokia's previous cheaper Windows Phone options. Those colors hit you right between the eyes, with matte- and gloss-finish covers in cyan, lime, yellow and magenta presenting a nice alternative to the more staid black and white versions. Behind that shell, a 1GHz Snapdragon S4 Plus beats away, with a bright 3.8-inch ClearBlack display beaming out a familiar 800 x 480 resolution.
Despite the price, it's running the latest iteration of Windows Phone 8 and Nokia's also ensured its own camera lens apps, along with its music and mapping services, have been carried over as well. The 5-megapixel camera may be bested by the Zeiss-equipped 8-megapixel sensors on its bigger brothers, but with a staggering £300 difference between the Lumia 620 and Lumia 920, what other sacrifices have been made? Is this the best bang-for-your-buck Windows Phone we've ever seen? We think it might be.

HARDWARE

After trying out both the Lumia 920 and the Lumia 820, it's a relief to see Nokia's phone footprint shrink so that it's closer to 2011's Lumia 800. The 620 model has a marginally larger screen than that polycarb-crafted phone, but it feels just as comfortable in our hands — one-handed use is a non-issue. While the screen's surface is completely flat, the edges curve around gently, forming a rounded back.
The entire cover can be pried off by pressing down on the camera unit and pulling at the top edge of the covering. Does it feel as plasticky as the Lumia 610? Nope. Wobbly? A little — there's a minor amount of give in the center of the back, but the cover and device feel unified and solid. Better still, due to the way the covers are formed (two different color layers, for the likes of the lime-green and orange options) they've come out in very vivid hues — the soft-finish cyan shell is this editor's personal favorite. The cases can also take a fair amount of damage from drops, with the easily breakable headphone port built into each case rather than the phone itself.
Nokia has added a front-facing VGA camera to this model (a first for an entry-level Nokia Windows Phone), while a 5-megapixel sensor and flash are centered on the back. For fans of the Lumia series, the front is even more familiar. The screen is framed with about 2mm of bezel at the sides, with space above it for the aforementioned VGA camera and earpiece. Below the TFT screen, you'll find the staple three-button capacitive control panel.
Along the right edge, there's still a hard camera button — and all the buttons seem to have more give than last year's Nokia devices. The micro-USB port sits along the bottom with the primary microphone, while the headphone socket belongs at the top, replete with a secondary mic. It's worth mentioning that the Lumia 620 has been gifted with the same distortion-free, high-amplitude mics embedded inside the Lumia 920 — more on that in the camera section. Meanwhile the Lumia 620's built-in speaker is apparently 20 decibels louder than Nokia's flagship phone, able to penetrate thin walls at a maximum of 100 decibels.
If you want your music louder, the phone is also compatible with JBL's wireless speakers through its built-in NFC, while a removable 1,300mAh battery resides next to the space for a microSD card. There's already 8GB of built-in storage from the outset, while Microsoft is still offering 7GB of cloud storage through SkyDrive — in short, there are plenty of storage options. There's just 512MB of RAM, but that's plenty for handling the existing app selection on Windows Phone — we didn't have any issues using Skype or other apps, although we can't vouch for how future-proof this phone will be compared to Windows Phone devices housing 1GB of RAM.
The handset isn't going to weigh pockets down at 127 grams, but it's not the most slender phone out there, either. At 11mm (0.43 inch), it's actually incrementally thicker than the Lumia 920, but with this smaller form factor you shouldn't have any issues with one-handed control. Nokia's new phone is more comfortable to use, even if that means there's less screen to play with.

DISPLAY

If you've been looking for a sub-4-inch Windows Phone 8 device, options have been pretty limited as of late. But here, you're getting a display that's appropriate for the price: a 3.8-inch touchscreen that matches the resolution of most Windows Phones — that is, 800 x 480. Nokia's included its ClearBlack tech and an RGB Stripe pixel arrangement, while adding an anti-glare layer to improve outdoor visibility. Stack it against the Lumia 820, and it requires a bit more explaining.
In a way, the 620's screen looks better — it's the same number of pixels in a smaller space, but it's no longer AMOLED. Colors appear slightly more muted on the 3.8-inch TFT in comparison, although it also lacks AMOLED's bluish overcast in white areas. Now, after dabbling with 4.7-inch displays you might think that the smaller display would make web browsing a little more frustrating, but page formatting remained pretty much identical among the three Windows Phone 8 Lumias.

CAMERA

If there was one feature that we expected to be underwhelming, it was the camera. Despite the extent to which Nokia raved about the prowess of its optical image stabilization and Carl Zeiss lens, you won't find either here. Maximum image resolution drops to five megapixels, but the sensor is still capable of 720p capture, with an LED flash potent enough to light up your subject — it's possibly a little too strong for close-up shots. The physical button launches into the camera almost immediately, with none of the lag of its predecessor, and with the same ability to lock focus with a half-press. We found in most situations that tapping the screen to focus offered a better lock.
The camera was able to take a handful of decent stills, although focus seemed slightly more temperamental than on other Windows Phones we've tested in the past. It still managed to give us some passable results in less favorable conditions, but if we were aiming for a close-up shot in better light settings, that reduced resolution made itself known in not-so-detailed results. That said, there's none of the fuzz and noise we've seen from other sub-£200 smartphone cameras we've tested in the past 12 months — we're pointing our finger squarely at some of ZTE's and Huawei's cheap carrier-specific models.
Unfortunately, we've still got the same complaints that we mention in most Windows Phone reviews: there's no HDR mode, the UI itself is relatively low on customizations and there's no way to lock down exposure to avoid blowing out your images in bright light. However, the Panorama mode (above) and Nokia's GIF-crafting Cinemagraph are worth installing as they both add some extra talents to the camera.
More interested in video? Well, the Lumia 620 gives a decent showing here too. There's no optical image stabilization, but that remains a very rare addition to phone cameras, so it's hard to hold it against a colorful, rich recording. While a bit of breeze buffeted the mics, it picked up our voice (and some waterfowl noises) with perfect clarity.

BATTERY LIFE AND PERFORMANCE

So, the Lumia 620 has the same resolution of the Lumia 820, memory expansion through microSD and even a pair of high-amplitude mics, but we had to see how Qualcomm's lesser Snapdragon S4 Plus processor would handle an almost-identical Windows Phone UX. You can lay any of those concerns to rest, as the 1GHz dual-core processor offered up a very similar experience; you're getting far more than what you pay for. We ran the Lumia 620 against both the Lumia 820 and Lumia 920, and found that the only major differences in performance were the startup times, with the smaller phone taking about five seconds longer to reach the home screen. Scrolling around on Internet Explorer 10 on any device resulted in largely the same level of speed and responsiveness, a testament either to Microsoft's mobile browser or to Qualcomm's processor know-how.
The 1,300mAh battery inside is smaller than the one found in the Lumia 800, although this time it's thankfully replaceable. During our WPBench rundown tests, which push the processor to the max until the battery cuts out, we averaged a time of 3:41. That puts it below the Lumia 900 but more than an hour beyond most Windows Phone 8 devices. It even bests the hardy HTC 8S. Naturally, this isn't representative of the battery with more moderate use, but the Lumia 620 did better in this regard, too. It typically gave us two days of use before cutting out. This entailed plenty of web browsing, listening to offline playlists and a handful of calls and email replies.
Its benchmark results don't stand up to phones with beastlier processors like the 820 or 920, but the 620 still manages a respectable sub-1,500 score on SunSpider. Meanwhile, the dearth of highly polished Windows Phone games to push the technical abilities of the hardware makes it even harder to differentiate real-world performance between the three phones. On the rare occasion the device froze, it was often during data upload from the camera app to SkyDrive, but the experience was otherwise smooth and without issue. The HSPA+ radio (WCDMA 850/900/1900/2100 and GSM/EDGE 850/900/1800/1900) promises speeds up to 21 Mbps down and 5.7 Mbps up. During our tests on Three UK, we were picking up download speeds of around 5 Mbps, while uploads hovered just below 1 Mbps. The good news is that this phone will work on both AT&T SIMs and T-Mobile's recently claimed 1900MHz HSPA+ spectrum, both data and voice. If Nokia US decides to offer the phone directly to customers, it could prove to be a tempting introduction to Windows Phone without the fiscal carrier hangover.

SOFTWARE

Read our Windows Phone 8 review? Or our reviews of those bigger Nokia models? Then sadly, there's not much new to tell you here. But that's actually good news — despite those lower specifications, the phone gets Nokia Music and Maps, not to mention those Lumia-specific camera enhancements. Mix Radio throws in a substantial amount of offline music your way for free, while Nokia's map navigation loads quickly and reliably. There's also the option to download countrywide maps ahead of any trips abroad. Problems still left to be solved include some major apps that are MIA, including Dropbox, Instagram and Spotify — the music service remains available on last-generation Windows Phone devices. Despite that Xbox brand association, gaming remains a shallow experience. If you're making noises about having Angry Birds in 2013, there's an issue.
It's also worth mentioning that after getting hands-on with (and feeling underwhelmed by) Windows Phone 7.8, we can't recommend picking up those old Lumia devices, even when they can now be bought for a similar price to this new Windows Phone. To get the full experience — and join an app selection that will grow in the future — you're going to have to pick up the Lumia 620, 820 or 920. Another benefit to the off-contract phone means there's no carrier bloatware to be found. The apps that do arrive pre-installed are mostly worth keeping around and getting rid of unwanted programs is just a long-press away.

WRAP-UP

The Lumia 620 represents a new high-watermark for entry-level smartphones, regardless of OS. Ignoring the app drawbacks, the phone provides a great web browser experience alongside the full Windows Phone 8 feature set. It could be a very exciting phone for Nokia — it's an exciting one for us. We've mentioned the price several times during the review, but for a new smartphone with the latest version of its respective OS, it's a steal. The phone might house a less-capable camera, but for anyone sick of oversized, unwieldy, expensive smartphones, Nokia now has an entry-level Windows Phone to lure the bargain-hunting crowds away from Android, if the Nexus 4 proves too expensive.
What's more, it's arguably more attractive than most Google-powered phones around the same price point and could prove to be a huge hit among smartphone beginners. There's also a good chance that the more-gadget obsessed might pick up the Lumia 620 as a second device to give Microsoft's mobile OS a try — and with compatibility on two US networks, it might be worth an import. It delivers real-world performance as good as Windows Phones that cost more than double. If anything, it's making us reconsider whether those other rivals are worth the extra outlay.

Google Nexus 10 Review ” features – display – screen – battery – memory “




Introduction:
Oh Nexus, it’s one of those familiar brand names in the industry that seemingly conjures up cutting edge devices meant to showcase the very best of the best in the Android sphere. This past summer alone, we were introduced to one game changing tablet in the Google Nexus 7 that redefined what it meant to be a budget friendly device. Stepping its games even further, Google is expanding its presence into the fuller tablet segment, which means that the competition will really need to take notice.
Apple surely surprised many people by introducing two new iPads just in time for the busy holiday season, one being a slightly upgraded fourth-generation 9.7-inch model, but it’s Google who seems to be getting the last word. In addition to announcing the fourth incarnation of the Nexus branded smartphone, Google also went forward to unveil its brand spanking new 10-inch Nexus tablet – the aptly named Google Nexus 10. With Samsung commissioned to manufacture this newest Nexus, combined with some unbelievable hardware specs for a $400 tablet, it’s going to be one all-out battle this crucial holiday season.

The package contains:
microUSB cable
Wall charger
Quick Start Guide
Warranty Guide
Design:
Constrained to fit within a budget, the Google Nexus 10’s design mirrors what we see out of the Nexus 7 already – meaning, it has a very modest appearance. Sure, it’s made by Samsung, but interestingly enough, it doesn’t look or feel like a Samsung-made tablet. Call it a sigh of relief, but we’re digging the direction of this tablet’s design, though, we wouldn’t necessarily say it’s the most attractive or sturdiest thing we’ve come across. Yes, it’s something that requires two-handed operation most of the time, especially considering it’s a handful using with one hand, since the uniform almost 1-inch bezel around the screen makes the tablet look bigger than it should.
However, we like how it maintains one clean appearance, thanks primarily to its gunmetal colored soft touch casing, which exhibits that distinctive rubbery feel in the hand. We’re glad to know it’s extremely svelte (0.35” thin) and lightweight (21.27 oz) – similar to some of its main rivals.
There are no capacitive buttons on this bad boy, of course. Instead, the only items we see on the front panel of the Nexus 10 are the pulsating LED notification light beneath its screen, and the front-facing 1.3-megapixel camera above its display, which can shoot video in 720p.
On the top edge of the tablet, its dedicated power button and volume control are positioned next to one another. Thankfully, they’re raised and exhibit springy responses, but when holding in portrait, we have to remember to move the placement of our hand to the middle area of the tablet to ensure there are no accidental presses.
Along the left trim, we spot its 3.5mm headset jack and microUSB port for charging/data connectivity – while on the right, the only item there is the microHDMI port. Unlike the Nexus 4, which relies on a relatively unknown Slimport socket for video-out, we’re ecstatic to know that Samsung and Google opted to employ a traditional microHDMI port for easier video-out functionality with the Nexus 10. Somewhat of an unfamiliar sighting from everything else, the tablet’s proprietary docking pins are located on the tablet’s bottom side, which are meant to accommodate whatever future accessories they’ll come out with.
Lastly, the 5-megapixel auto-focus camera with LED flash is perched directly along the top-middle section of the rear casing – surrounded by its dotted patterned casing. Interestingly, there’s a notch towards the right side of the patterned surface that enables us to pry it off – revealing spots that are potentially placeholders for SIM cards, or possibly once microSD slots.
Display:
Getting the last laugh before we call it quits for the year, the Nexus 10 shoves everything else we’ve seen in the past aside, as it gloriously features one sharp looking 10.05-inch True RGB Real Stripe PLS display. For those wondering, its resolution is actually better than 1080p – it’s at a mind blowing 2560 x 1600 resolution to be specific, which conjures up an amazing pixel density of 300 ppi! No doubt our eyes are livid about looking at this immaculate looking display, since it flaunts details like no other tablet before it. Everything seemingly pops with superior clarity and sharpness that’s unmatched at this point!
Color-wise, there’s a dab of saturation evident with the display, which no doubt goes nicely with its warmer color tones. Throw in its superb viewing angles and mighty strong brightness output, the Nexus 10’s display is easily visible in outdoor conditions with the sun bearing down upon us. So yeah, there’s no arguing this is the cream of the crop in terms of tablet displays at this very moment! Needless to say, we have to give some kudos to Google and Samsung for their effort, even more knowing that this is a $400 tablet we’re dealing with!

LG Spectrum 2 Review ” features – battery – memory – screen – display “



Introduction:

With the Holiday Season fast approaching, Verizon has introduced the new LG Spectrum 2, which is a follow-up to the original LG Spectrum that was released earlier this year. This time around, the device is more in line to compete with other mid-level smartphones, as it comes running Android 4.0.4 Ice Cream Sandwich and features a 4.7” 720p display, a Qualcomm 1.5GHz dual-core Snapdragon S4 processor with 1GB of RAM, and an 8MP rear camera. But what makes the LG Spectrum 2 most attractive is its reasonable price, coming in at $100 with a 2-year contract.
Included in the retail package is the LG Spectrum 2 VS930 smartphone, 2150mAh battery, two NFC Tags, wall charger with detachable microUSB cable, and user guides.
Design:
Calling on elements of the LG Optimus line, the LG Spectrum 2 is a bit more refined than the original Spectrum phone, though it looks like the “monolith” from 2001 A Space Odyssey. Despite this, the Spectrum 2 feels solid and well made (almost brick-like), with black on the front and back being framed by chrome accents around the edges. We welcome the textured soft-touch battery cover on the rear, as it provides a firm grip.
The front of the Spectrum 2 is mostly occupied by the display, above it is a 1.3MP camera, and below it are four capacitive buttons with blue LED backlight. Around the sides we find the microUSB port, 3.5mm headset jack, as well as the volume and power/lock buttons – which have a distinctive feel to them since they are raised from the surrounding edges. While on back is the 8MP autofocus camera with LED Flash. The microSD memory card slot and SIM slot are hidden by the battery cover.
 Built into the battery cover is NFC (near field communication) and wireless inductive charging. To make use of the NFC, the Spectrum 2 includes two LG Tag+ stickers, one for the car and one for the office. The car tag will active the Google Maps app on the phone, while the office tag will place the phone in vibrate mode and turn on Bluetooth. But in order to use the wireless charging, you have to purchase the wireless pad separately, which still requires a wall outlet connection.
Display:
One nice improvement with the LG Spectrum 2 is that it is using a larger 4.7” True HD IPS display, up from 4.5” on the original model. It comes with a 1280×720 pixel resolution, and uses the more favorable RGB arrangement instead of PenTile. Overall, the True HD display on the Spectrum 2 is sharp and crisp, with text and images having fine detailed edges, and color accuracy is spot-on, though not as eye-catching as AMOLED displays.
We’re also pleased by the brightness of the display, using LED backlighting, which makes it plenty bright enough to view in sunny conditions. However, it is unfortunate that the display suffers from poor viewing angles; as when not viewed from the dead center, there is noticeable loss in contract and color saturation.

Sony Xperia SL Review ” features – battery – screen – memory “




Introduction:
Sony did with the Xperia SL what it did with the Xperia arc and arc S last year – a new version with more colors, newer Android version, and souped-up processor speed. The only notable difference between the specs of the Xperia S and the SL, is that the dual-core Snapdragon S3 processor went up from 1.5GHz to 1.7GHz.
Other than that, ICS and the few fun new colors, like the pink SL unit we have here, it carries the same 12MP camera with Exmor R sensor, and is shipping with the same generous 32GB of internal memory, as the Xperia S. Is there anything new in the performance aspect? Read on to find out…
In the box:
Wall charger
microUSB cable
Warranty and information leaflets
Sony in-ear headset
Design:
The phone looks like a boxy slab, and weighs more than usual for a 4.3-incher, yet when picked provides a firm grip precisely because of the sharp edges. It still offers the slightly curved back of the former Xperias for added grip comfort, but its matte plastic is a bit slippery, so the phone not being overly thin as some other anorexic handsets helps to grip it tight. The boxy phone has this rugged good looks, which the girly pink version we got tries to balance out.
Sony has gone with the narrower but more elongated design that first appeared in the Xperia arc, and which we very much appreciate, as it allows your thumb to reach more places on the screen. Even if your hands are not as large, you’ll still be able to navigate fairly comfortably the interface with one hand, compared to other big- screen phones that come wider.
Speaking of one-handed operation, the Xperia S offers good weight distribution, not most of it concentrated in the upper part around the camera module, as is so often the case. Thus we weren’t worried that it might tip over when we push it up a bit to press the three capacitive Android buttons under the display.
We had a ho-hum experience with these buttons – the transparent strip that is a trademark of Xperia's NXT design line lights up with the Android navigation symbols like a back arrow or home, but the keys are three teeny-tiny dots above the respective icon lit up in the strip, and are very easy to miss. You have to tap precisely on the miniature dot, and they are not very responsive to boot, making us tap two or three times to register an action very often.
There is no arguing that the transparent illuminated strip is a thing of beauty, though, and the contrast with the edgy black slab when it lights up leaves a very futuristic impression, which Sony has been aiming for with the “Iconic Identity” design. The firm says that this strip, which also houses the antenna parts for improved reception, is meant to emphasize the screen part above it.
Looking around the sides we barely notice any buttons and ports, we notice the microUSB and microHDMI ports covered with protective flaps in the chassis paint too. The flaps are a bit hard to pry open, especially if you are the nail-biting type, and even harder to push back in, but they should break in with time.
The volume rocker and the two-stage camera key on the right, as well as the lock/power button at the top are painted silver, distinct to find and tactile. The rocker in the middle of the right side, however, sits too low, and tends to get operated with the thumb joint instead of the tip.
Display:
We have a 4.3” HD display with 720×1280 pixels of resolution on the Xperia SL, the same one we have on the S; we have 342 ppi pixel density, one of the highest of all HD mobile screens, since most others are bigger. We get crisp small text, no icon jaggies, and readability even for zoomed-out websites.
The LCD screen is bright, with popping colors, but the horizontal viewing angles degrade the image more than they should on a high-end screen. Sony has included its Mobile BRAVIA engine that boosts colors and contrast while watching media, which can be turned off. Brightness and screen reflectance are decent, so outside visibility will only be an issue if the sun shines directly onto it. The touch layer is very responsive and registers even the slightest finger tap.

Microsoft Surface RT Review ” features – memory – screen – display “



introduction:
Microsoft, as we know for a long time now, has always had a formidable presence in the computing space. Even now, they still command a sizable piece of the pie, but as we’ve seen, there is a stark shift in what people are using on a daily basis for their computing needs. A few years ago, everyone seemed intent on riding the wave surrounding netbooks, but as we’ve witnessed, it was short lived. Ultimately, Apple redefined the entire computing spectrum with the introduction with the iPad – and of course, the rest was history. Continuing to dominate the scene, consumers quickly realized the advantages that tablets have to offer over traditional laptops. And for a while there, Microsoft sat content in pushing forward with its usual computing platform offerings.
Thankfully, they too quickly realized how tablets are increasingly outpacing laptops – as they prove to have that killer combination of pricing and mobility to attract consumers. Interestingly, rather than following the same routine of just solely building its own tablet platform from the ground up, the Redmond based company is relying on itself to produce its own device as well – much like what we’ve seen with the Xbox and Microsoft Zune (and the Kin phones). Enter the Microsoft Surface, a sleek and ultra-modern looking tablet that’s gunning to make a charge in the competitive tablet market. More importantly, however, is whether Microsoft is able to soundly capture the embodiment of a highly usable tablet platform with Windows RT. Naturally, there’s a lot at stake riding on the back of the Surface – both from a hardware and software perspective.
The package contains:
AC wall charger
Touch Cover (sold separately or as part of a bundle)
Design:
From afar, the Microsoft Surface looks like any other slate out there sporting one cookie cutter industrial design, but once it’s in our hands, we soon realize that there was a lot of love placed into it. Indeed, it’s not the skinniest (0.37” thin) or most compact tablet out there, but it has all of the required elements to make it an attention grabber against most other things out there on the market. For starters, its tapered edges help to give it a distinctive look of its own – while its magnesium composite chassis, which is a material that Microsoft calls “VaporMg,” comfortably adds a sense of strength and durability to its construction. Fortunately, the Surface manages to maintain a clean façade, as it does a good job of repelling dirt and debris from dirtying its uniform looks.
In addition to that, there’s a reasonable amount of weight (24 oz/680 grams) to instill in us that it’s one solidly made thing. Compared to some of the other venerable tablets on the market, the Surface’s design is right up there and in the same league as the iPad and Asus Transformer Infinity Pad, but we’re most humbled that Microsoft is able to distinguish its offering enough to give it a defined look that’s attractive in many fronts. Taking into account that it’s not too often we find Microsoft helming the design process, we’re undeniably impressed that they’re able to execute it unequivocally so well with this.
By default, Microsoft has made it so that the Surface is primarily held in landscape, and with that in mind, there’s a capacitive Start button below the screen, which merely brings us back to the Start Screen. Above the display, we find its 1-megapixel front facing camera, which has the ability to shoot HD videos too. Nearby, there’s also an LED light that turns on to indicate that the front camera is in use – nothing more than that.
Along the top edge of the tablet, we’re presented with its slightly raised & springy power button and two small notches that initially appear as being part of its speakers, but rather, they’re actually microphones. As for the speakers themselves, they’re located on the upper sections of its left and right trims. To the left, though, we find the volume control and 3.5mm headset jack – while on the right, there’s a full sized USB 2.0 port to connect a variety of accessories and peripherals to the Surface, microHDMI port, and its proprietary magnetic power connector. Finally, the sole item spotted in the bottom trim is the proprietary magnetic accessory connector – for the optional touch covers and type covers.
Flush with the surrounding area, the Surface is packing along a 1-megapixel fixed focused rear camera, which can shoot videos in up to 800p. Just like before, an LED light sits close by, but it doesn’t do anything except to indicate that the rear camera is active.
Not something that’s normally seen with tablets, the Microsoft Surface incorporates a very useful kickstand that firmly locks into the open position. In fact, it’s strong enough to even prop the tablet in portrait – though, its primary function, in addition to giving us a hands-free video watching experience, is to allow us to properly use the tablet along with its optional Touch Cover. Lastly, discretely ticked away under the one side of the kickstand is a very handy microSD card slot.
Display:
Opting for the wide screen format with its display, the 16:9 aspect ratio of the Surface’s 10.6-inch screen makes it ideal for watching videos, which is made better with the kickstand in play. However, knowing that it’s sporting a less-than-spectacular resolution of 1366 x 768, it’s not going to be garnering much attention over the higher resolution displays used by its main rivals. Sure, we’re able to read text from a normal distance away with few nagging issues, thanks to Microsoft’s ClearType sub-pixel rendering technology, but upon closer inspection, we can actually make out individual pixels.
Although some might not fancy knowing it’s boasting a lower contrast level than other displays, it actually makes for a better reading experience thanks to reduced eye fatigue during prolonged viewing. Similar to the iPad 3, the Surface’s display emits warmer color tones, which truly shows off its vibrancy when its brightness is cranked all the way to its maximum setting. On top of that, its wide viewing angles combined with its 400-nit brightness setting helps to maintain its visibility – especially when it comes to outdoor viewing. Noteworthy to mention as well, the Surface features an optically bonded display, similar to in-cell touch technology used by the iPhone 5 and LG Optimus G most recently, allowing the screen to be closer to the surface of the display. There’s no arguing it gets the job done with most benign things, but above all, its low resolution doesn’t do justice in giving its display the sharpness it needs to polarize prying eyes.
Touch Cover:
If you haven’t noticed it already in the Microsoft Surface commercials, the secondary star attraction of the Surface is the optional Touch Cover, which retails for $120 when bought separately and is available in different colors. Acting as a smart cover on one hand, the Touch Cover firmly snaps into the Surface’s magnetic connector dock – with an audible thud sound to indicate it’s positioned correctly. And boy is the connection strong! So much so that it can hold the entire dead weight of the Surface as it’s dangling. Of course, it’s also there to protect the display when it’s closed.
Secondly, the Touch Cover provides us with a full-sized keyboard with directional keys and a trackpad. Lined with a fabric-like material, it manages to retain a very clean appearance at all times, but there’s very little distinction between buttons because of their flush appearance. Sensitivity is hit and miss in our experience, as light taps aren’t registered sometimes – resulting in firmer taps of the finger. To tell you the truth, we find ourselves more productive typing with Surface’s on- screen keyboard. Still, it feels more natural typing things up when propping the tablet on its kickstand and using the Touch Cover, as opposed to laying the Surface flat on our lap to use the on- screen keyboard. If you prefer physical responses, you might want to consider picking up the Type Cover, which is thicker in size and priced a little more at $130, but offers the tactility of real buttons.
