Touchscreen Test
Test multi-touch, detect dead zones, and verify digitizer tracking. Best used on a mobile device or tablet.

Why Test Your Touchscreen?
Your touchscreen is the primary way you interact with your mobile device. Dropping your phone, water damage, or even extreme temperatures can cause micro-fractures in the digitizer beneath the glass. This can lead to 'dead zones' (areas that don't register touches) or 'ghost touches' (screen tapping itself).
Multi-Touch Capabilities
Modern smartphones typically support up to 10 simultaneous touch points, allowing for complex gestures like pinching, swiping, and multi-finger gaming controls. Our test tracks every single touch point independently, assigning a unique color and tracking its precise X/Y coordinates in real-time.
Finding Dead Zones
To test for dead zones, slowly drag a single finger across every inch of the testing area, moving in a grid pattern. If the glowing trail suddenly stops or jumps while your finger is still touching the screen, you have found a dead zone in your digitizer.
