The most comprehensive toolbox to save battery, tweak, tune, backup, secure and monitor any Android devices running any ROMs, any kernels.
What is Android Tuner
Replaces 20+ apps easily worth 30€ for the price of a couple of beers!
Safest root app on Play Store: I run the app and all its features on at least 4 devices every day, and change 3 of them frequently for testing purposes. With about 250.000+ actual users, it's pretty safe to assume the app is very safe. App can create a reset package to disable all system tweak features from CWM/TWRP at any time. App has automatic fallback in case of boot loops while re-configuring the CPU.
