What is the Touch Screen Test?
Check if every part of your phone or tablet screen responds to touch. Draw across the full-screen canvas to find dead zones (areas that do not respond), and put several fingers down to see how many touch points your screen supports at once.
It is useful before buying a used phone, after a screen replacement or when you notice ghost touches.
How to use the Touch Screen Test
- Press Start test – the test opens full screen.
- Draw lines slowly over the entire screen, including the edges.
- Any gap in your lines may be a dead zone. Put multiple fingers down to test multi-touch.
- Tap Exit (top corner) when done.
Grid mode
Turn on the grid and try to fill every square. Squares that stay empty after several attempts point to a faulty area.
This Touch Screen Test is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
