Registering new Nexus 7 on Asus website

The new Nexus 7 is quite a device – some say that the price was subsidized by Google, which explains the high quality hardware found inside.

Since already there are many owners of the Nexus 7, some of them are experiencing difficulties in registering their new gadget in the Asus website. For those of you who have the same problems, please bear in mind, that the SSN (serial number) found in the device firmware is not the one that has to be inserted in the website.

Nexus 7 serial number (SSN) is found on the box and consists of 12 symbols – 6 letters and 6 numbers. Most common mistake is that 0 (number 0) is typed instead of O (letter O), and that’s simply because it really looks like a number on Nexus 7′s box.

4 Tips to clean Android Smartphone or Tablet Screen safely

Do you wash your hands before you handle your smartphone or tablet, each and every time? Chances are, your device could use a good cleaning. Here’s how to safely clean your smartphone or tablet:

How do I safely clean the screen on my smartphone or tablet?

To clean the screen on your smartphone or tablet, use a soft, lint-free cloth. We suggest you pick up a couple of microfiber cloths. Never use a paper towel or other paper-based towels as they can leave scratches on the screen. For fingerprint smudges, dust, and lint, wipe the screen gently using a dry microfiber cloth.

What if I got ink, food, or makeup on the screen?

For more stubborn contaminants or stains, turn your device off and remove the battery if possible. Lightly dampen a section of a microfiber cloth with water and gently wipe the screen, then go over it again with a dry section of the cloth to wipe away any moisture. Avoid getting moisture in any openings like the speaker or mic. If the stain remains, you can also try using a mild soap-and-water solution. When your device is completely dry, put the battery back in and turn it on.

Can I use Windex or other household cleaners to clean my device?

Never use window cleaners, harsh chemicals or cleaning solvents on your smartphone or tablet and never spray anything directly onto the screen. Some screens, like those on the iPad and iPhone, have a special coating that can get wiped away if you use chemicals to clean the screen.

What if my device gets wet? Can I use a hair dryer or uncooked rice to dry it?

If your smartphone or tablet happens to get wet, turn it off immediately and remove the battery if possible. Let it dry for as long as you can before turning it back on and never use a hair dryer, oven or microwave to try and accelerate the drying. Some people have claimed that leaving a wet device in a bowl of uncooked rice helps get the moisture out of the device, but your mileage may vary. There are also a couple of companies that make kits that claim to dry out wet devices. One such kit is called the “Dry-All First Aid Kit” and is available from

There, now you know how to clean your smartphone or tablet. If you’ve used one of those drying kits or tried the uncooked rice method to dry out a wet device, let us know how it worked out for you in the comments.


3 essential apps for tracking Android data usage at a glance

If you have a grandfathered unlimited data plan from your mobile carrier, hold onto it like it’s unobtainium. For those of you just now joining the smartphone movement on Verizon or AT&T, you’ll have to choose a tiered data plan. Don’t worry, though; we’re here to help!

Here are a few apps to track data usage on your Android phone.

Carrier app

The simplest way to track data usage on your Android phone is by using apps from your mobile carrier. Verizon’s app is called My Verizon, and AT&T’s app is called myAT&T. Both apps provide information on your data usage based on the information stored on their remote systems. Verizon’s app also includes a small widget that displays your data usage.

3G Watchdog

3G Watchdog is a free app available from the Android Market that keeps track of your phone’s data usage. It uses the raw data from the phone itself to count data usage.

After installing 3G Watchdog, set your quota, billing cycle, and alert settings.

Once it begins collecting data, a table will appear on the main screen that shows your usage.

You’ll also notice a new icon in your notification bar that changes colors (green/orange/red) depending on how close you are to reaching your quota. 3G Watchdog also includes a simple widget that provides usage data at a glance.

My Data Manager

My Data Manager app

My Data Manager, like 3G Watchdog, is a free app that collects data usage directly from your phone. The difference is, My Data Manager provides usage statistics for individual apps on your phone. This is an excellent way to identify which app or apps are data hogs.

After installation, enter the details of your data plan into My Data Manager.
Once it begins accumulating data, you’ll see a list of apps, sorted by their data usage. The widget for My Data Manager displays usage data for mobile, roaming, and Wi-Fi.

There you go. Now you can keep track of your data usage so you don’t accidentally go over your tiered plan.


Maximize Android screen space with 5 tricks for best organization

No matter how tricked-out your Android layout is, you’ll always find something new you want to do that takes one click too many to reach. Just as all projects go over budget, all your favorite apps and bookmarks are sure to spill over beyond your home screen. There’s no one perfect solution for everyone, but there are a few habits and tools that can help keep your digital life close at hand.

Be ruthless.

Clear your device of any applications you don’t use, and clear your home screen of everything you don’t either use every day (like Foursquare) or need to access instantly (like the QikCam photo widget). You shouldn’t agonize over your choices–remember that you can always add apps or widgets back in if you miss them too much.


An office-themed screen
An office-themed screen

This is key. Just a few minutes of rearranging icons can save you time, energy, and frustration over the long term. You don’t need to arrange everything alphabetically; just make sure that your screens make sense to you. Typically the home screen is best for frequently used apps, while other nearby screens are for apps you want to be able to access quickly (but don’t need to access instantly). Having themed screens such as a media screen and a fitness screen often works well.

Use folders.

If you don’t mind two-click access, adding a folder or two to your home screen can add acres of virtual screen space. It’s easy: just long-press the screen, select “Folders,” and select a type, typically “New folder.” To name the folder, open the folder by tapping it, then long-press the extra-boring default name (“Folder”) and type in a new, memorable name. Organize these folders however you like, but it’s best to keep each one down to 12 items for easiest access.

Rely on notifications and streams

Do you really need your e-mail or Gmail apps available on your home screen? Unless you’re initiating new messages every day, the answer is probably no. In your account settings, just make sure that your apps check for e-mail frequently and deliver notifications to the top bar. This can also work well for Facebook and other services that deliver notifications in the top bar or can be accessed as streams on less valuable screen real estate.

Try SmartWidget or other app launchers.

SmartWidget is a useful, free app with a widget that takes up four slots on your screen, which seems like far too much until you learn its secret. It gives you access to the four most frequently used apps on your device–except those that are already on the home screen. This is a clever bit of wizardry that could save some time and effort for those of us who are constantly installing new apps. There are plenty of other app launchers out there, so find the one that works best for you.
