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.
    Tip: You can exit the test early by pressing any key on an attached keyboard and pressing Exit.

The test will repeat three times and then exit.
