A coverage map, not a hardware scan.
Browser gestures and screen edges can intercept touches. Revisit empty squares slowly before drawing a conclusion.
How to use this test
- Touch the grid with your finger or pen.
- Move slowly across every region.
- Revisit empty squares before recording the coverage.
Are empty squares definitely touch dead zones?
No. A fast movement can skip samples, and browser gestures can intercept input. Repeat slowly. A mouse is not accepted as touch input.
