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.
