OLED Saver APK

Run this application called OLED Saver or download it using ApkOnline. You can do this with our online Android emulator.

Prevent screen burn-in on vulnerable devices such as those with OLED and AMOLED displays. This app will fill the screen with pure black color and prevent your device from going to sleep while it is in the foreground.

Some common uses are:
Video chat or conference call so that the camera stays on and the call stays active, without burning the app logo into the display. If the video app supports overlays, they can still be drawn on top of OLED Saver, as shown in the screenshots.
Run a process in the background (such as cryptocurrency mining) when you want the device to be fully awake, but without damaging the screen or wasting power.
Anytime you want your screen off but your phone active and unlocked for quick access

Note. This app also works on LCD screens, commonly called LED screens, will go as black as the screen can manage, but the backlight usually stays on.
