Now wondering what to do with your rooted phone?
Here’s the answer for you!
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 custom roms.
How to keep Root after OTA Updates
The OTA updates rolled out by the manufacturers wipe the root access on your phone. In case you don’t know how you can restore the root access after OTA update, you’ll have to root your phone once again, but there is no need to do it as you can restore it using the OTA Rootkeeper App which is available in the Google Play Store. The app creates backup of your root and simply restores it after any OTA update.
