Samsung unveiled a smart watch some time ago along with the coveted Galaxy Note 3 Phablet and provided it in a bundle offer which was actually a sweet deal. But the use of the smart watch which is actually not that smart is pretty much limited to the phone and it can only be used to tell the time and some basic functionality that too when connected to the phone via an internal tethering app. But leaving all that aside, if you are a geek interested in playing with these type of devices at the grassroots level, then this can be your new toy.
How many of you know that the smart watch can actually work as an independent Android device? Well, there is still no provision to actually root the device, so getting the bundled Google package is still out of question, but you can still use some simple apps like candy crush.

Samsung Galaxy Gear

Samsung has actually done half the work for us as the Galaxy Gear ships with a “USB debug” check-box in the settings. You just have to check that box, hook it up to a computer, and it will be usable with the Android Debug Bridge (ADB). ADB will now allow you to open a command line and you can then load whatever you want onto the Gear. It has only 4GB of storage so don’t overload it or it may crash.

The Gear comes with an 800MHz processor and 512MB of RAM which is pretty decent for running real apps just like any other Android device. Also it runs Android 4.2.2 which is fine and also considering that the old android devices used to contain less than half the specs of the Gear, it is pretty good that the Gear can double up as a great device.
Now for that the procedure is actually a bit time consuming but fairly simple. First you’ll need to get ADB on your system, so for that install the Android SDK on your system. Then connect the Gear via USB and turn on “USB Debug” in the settings. Once the Gear is recognized, you’ll be able to use it with ADB. Now for the apps that you want to install, you will have to get their APK files from outside source as you cannot get them from the Play Store on this. Once you have the files you want, open a command line and a simple “ADB install [file-name]” will do it. After a few seconds, your apps should pop up in the app drawer, and then pray and open up the application. Loading the media uses the “push” command and requires a destination. “adb push breaking bad.avi /sdcard/movies” should work perfectly.
Now you can check out the apps and also use it play local media like songs, videos, etc. one limitation to this is that you can only connect the device to the internet via the tethering option of the phone or else the in-house app for controlling the Gear from the phone. It does not have an internal option to independently connect to Wi-Fi which is a bit of a deuce.
So if you are a player with such stuff, you will certainly enjoy playing with the Galaxy Gear and well, you can literally play on it. Since the screen is only 1.6 inches, you might feel like losing your eyesight in some, so beware of that. But other than that it cool that you can use real apps on the Galaxy Gear. So enjoy with a playable watch now. It is a good option if you suddenly happen to run out of juice on your phone and are still hungry for some entertainment.

Here are some tips to back-up your Android device without rooting your phone.

Installing the Android SDK

Downloading Android SDK is the first step .We need to use the Android Debug Bridge or adb command to carry out backup process. Android Debug Bridge command is incorporated with Android SDK and it can be downloaded free. Before hand, install Oracle’s Java Development Kit for SDK and you need to download 32-bit version JDK and then download SDK from Google. After the installation of both is completed then open SDK Manager from Start Menu or search SDK Manager. After the SDK Manager is opened, enable the Android SDK Platform-tools checkbox and click to Install button and install platforms tool package, which will contain adb in it. If you get any type of error then run the SDK manager as Administrator

Device Setup

In your phone you need to check USB Debugging mode which can be done by moving to Settings of your phone and then to Developers option. Once the USB Debugging mode is enabled then connect your phone to computer via USB cable and be ready for next step which is Testing ADB.

Testing ADB

Adb file is already installed on your computer now and the path where your installed Android SDK and open the Command Windows here and if you are unable to locate the SDK path then go to the following path and you will find it C:\Users\NAME\AppData\Local\Android\Android-sdk\platform-tools so now you know how to move to platform-tools folder now go to this folder and Open command prompt by holding Shift and right-click and you will be able to see your device in the list, after you see the phone name in the list go to the next step which is Backing up your Device.

Backing Up Your Device

Now we can create a backup file of your device fully with the help of adb backup command. All you need to type the below command adb backup -apk -shared -all -f C:\Users\NAME\backup.ab and this will backup all your files and folders like installed apk files and storage card data to specific folder and you can see the backup of your files at this path C:\Users\NAME\backup.ab file on your computer. There can be confusion with the path so you should replace NAME in command with another username of your windows to save your backup file at another location. In this way you can backup your device and it will take some time depending upon the size of your data.

Restoring a Backup

You have created backup but you may need this backup some time so in that case you should know how to restore your data again to your phone and this can be done simply by running following command adb restore C:\Users\NAME\backup.ab and your files will be restored again. You might be asked with if you need to do full restore, if you enable yes then all your existing data of phone will be erased with backup contents. In this way you can restore and backup all Android device easily.
