How do I test my touch screen?

Open the touch screen test above and drag your finger across every part of the grid. Squares light up where touch registers, so any square you cannot activate is a dead zone. The test runs in your browser on phones, tablets, and touchscreen laptops with no app needed.

How do I find dead spots on my touch screen?

Slowly trace horizontal and vertical lines across the whole grid. If the trail breaks in the same place every pass, that area has a dead zone. Test with multiple fingers too, since some digitizer failures only appear during multi-touch.

Is this touch screen test free?

Yes, the touch screen test is completely free with no download, app, or sign-up. Use it before buying a used phone or tablet, after a screen replacement, or to document a defect for a warranty claim.
