What is the Touch Screen Test?
A touch screen that ignores parts of the display, or registers touches that never happened, is hard to diagnose by feel. This test gives you a black canvas: every finger you put down draws a coloured dot and trail, with a live count of touch points and the highest number of simultaneous touches your screen managed.
The screen is also split into 48 squares that turn green the first time they are touched. Swipe across the whole display and any square that stays dark marks a dead zone. Ghost touches show as dots you did not make. It works with fingers, styluses and even a mouse, so you can test on phones, tablets, touch laptops, kiosks and drawing displays.
