To Perform a Pattern Test on the Touchscreen

The pattern test allows you to visually check the performance of the touchscreen as it cycles through a number of patterns and colors.

  1. Press HOME > More > Diagnostics > Panel Diagnostics > Touch Screen > Test Pattern.

    The touchscreen cycles through a number of test patterns of different colors.

  2. Confirm that the touchscreen is showing the pattern correctly, and that the colors and brightness are consistent.
    Tip: You can tap the screen to pause and resume the test.

The test will repeat three times and then exit. You can exit the test early by pressing any key on an attached keyboard.
