Power Menu (root)

Require rooted device, won't work otherwise

Important notice on Android 6.0+:
When you perform a reboot to recovery, the system dialog would incorrectly state as performing a factory data reset. Please be assured that this app would NOT factory reset your phone and it is purely a visual bug. Hopefully Google would fix it in future revision of Android

Features:
Power off
Sleep (Screen lock)
Reboot, soft reboot (require busybox), recovery, bootloader
Screenshot
System menu override (experimental)
Quick setting tiles

Languages:
English
Russian (contributed by Виталя Борисов, thanks!)
Brazilian Portuguese (contributed by Lucas K., thanks!)
Simplified Chinese (contributed by Matsuri, thanks!)

Notice:
Screenshot may not work if you have "mount namespace separation" enabled in SuperSU

Installing as System App (technical read):
On Android 4.3+, you can freely choose whether to install our app to /system. Running as a system app would grant us extra permissions to invoke some protected functions (like shutdown/reboot) via the Android API. Otherwise we'll fallback to root shell commands, which could be slower depending on your device. However modifying /system would most likely hinder your ability to receive an OTA update

If you do opt to install as system app, you'll have to remove it from /system first in order to uninstall completely. You can do so by opening the config and clicking "Undo system app installation"
