The app utilizes amazing Xposed framework coded by recognized
developer rovo89 which, briefly, provides interface for injecting code into any app, including system services allowing modifications of applications and system services at run-time. One of the biggest advantages of GravityBox is that it is not bound to any specific device. Actually, it should run on any device having vanilla Android 4.1/4.2/4.3 (ROM close enough to AOSP).
This project wouldn’t be possible without rovo’s Xposed framework, so huge kudos to him.
GravityBox provides 2 main groups of features:
Fixes – help to fight typical MTK6589 bugs like:
