How to use Touchscreen Dead Zone Test

  1. Open Touchscreen Dead Zone Test on the same browser and device you want to diagnose.
  2. Touch pages use browser pointer and touch events exposed by the device.
  3. Run the visible touchscreen test controls and watch the live result area update before judging the hardware.

How to read the result

Touchscreen Dead Zone Test is most useful when you read the result as a practical browser diagnostic. Screen protector thickness, hand position, browser gestures, and OS touch filtering can affect contact data. A repeated pattern across multiple runs is more meaningful than one isolated spike, missed event, or visual artifact.
