Sony unveiled Xperia Z1 compact in January, 2014, a mid-range sibling of the original Xperia Z1. The device sports a very nice 4.3 inches IPS display with 342 ppi. Sony has powered it up with Qualcomm Snapdragon 800 Quad Core CPU clocked at 2.2 GHz accompanied by Adreno 330 GPU and a RAM of 2 GBs is placed on board. At the back, a 20.7 MP shooter is fixed while a 2 MP is fixed on the front. Xperia Z1 compact runs on Android 4.3 Jelly Bean out of the box, but Sony is doing true justice with the software updates and isn’t taking long to provide the latest and greatest version of Android for its mainstream devices. Xperia Z1 compact is currently running on Android 4.4.2 KitKat firmware based on the build number 14.3.A.0.757. All these nice specifications make this device a good to go with choice.

What to do once you’re rooted?

Rooting your phone gives you complete access over all the data which is apparently locked by the manufacturers. This includes removal of the factory restrictions and making changes to the internal system and the operating system. Gaining the root access gives you the privileges to install various applications to enhance the performance of your device, allows you to remove the built-in applications/programs, helps you to upgrade the battery life of your device & install the apps which require the root access for the proper functionality and modify your device in so many other ways e.g using mods and flashing custom recoveries and custom ROMs. Here’s our collection of 10 Best Root Apps.
