Display Tester Pro APK makes it possible to test almost every aspect of your device’s LCD/OLED screen. Using Google Cast, it is possible to test the display quality of your TV. It is designed to allow full-screen testing on devices with soft keys (hiding the soft keys in ICS and, later, immersive mode in KitKat and later).

Softkey hiding in ICS/Honeycomb/JellyBean
Use the preferences menu option for this or simply long touch the display during a test is running.


  • Slide left-right: change test image
  • Slide up-down: change brightness
  • Long touch: switch between full screen and normal screen (Android 3.0 and higher)
  • Double tap: hide or show the test-specific settings dialogue (if available)

When the soft keys are hidden, it is not easy to advance to the next screen: First tap to make the buttons appear, then a quick swipe for the next screen before the buttons are hidden again.

Please consider purchasing the Pro version to support further development.
