Proximity Service app allows you to use your Android device's proximity sensor to keep the screen on or off. Covering the sensor will turn the screen off but will keep the device awake, which is ideal when you are running applications or games in the background. This app is perfect for those who play idle games.

To utilize the service, simply open the Proximity Service app and follow the on-screen instructions. If you want to turn the screen off, simply cover the proximity sensor with your finger or any other object. Once you remove your finger, the screen will turn back on.
