Pressing the power button on your phone whenever you want to screen off or screen on is a tedious task.
You can minimize the usage of power button by following the instructions I explained in this video demo. The Android app I demonstrated in this video helps us to turn screen on simply by waving over the proximity sensor of our Android phones.
It keeps the screen on when we are using it by detecting motion, tilt angle, accessing notifications, while in call and while charging whatever criteria we want to follow.
