Runs great on devices like Google Pixel, Nexus, Samsung Galaxy, Note, and more.
It works by showing a black overlay on top of the screen and on modern AMOLED displays this turns off all pixels effectively turning the screen off.

Please note this is NOT a lockscreen app, It is an overlay, and your phone is not sleeping while this is on. So power reduction is mostly from less screen usage, and helpful to prevent screen burn in.

Primarily developed for turning screen on easily while developing apps, this app can be used in many scenarios like recording long videos, watching videos online for playing music, etc.

It requires the following permissions to function:
* Draw over other apps - in order to draw black screen simulating off screen on AMOLED devices.
* Run at startup - to start the service if the app was running before shutting down.
* Phone State - if a call is incoming, switch off black screen.
* In app purchases - to make donation.

Designed for AMOLED (OLED) screens.
