Touch screen test
Use the touchscreen itself to trace nine zones and see where this browser receives touch input.
Trace all nine zones
Open this page on the touchscreen itself. Tap or drag a finger or stylus through every numbered zone; the browser marks zones where it received touch input.
0 of 9 zones received touch or stylus input in this browser.
This records browser pointer events only. It does not prove that every physical touch point works or diagnose the digitizer; a desktop mouse click does not count as a touch check.
Open this page on the device you want to check. Touch handling may vary by browser and input method. If a zone misses touch input in ordinary apps too, follow the device maker’s touchscreen diagnostic guidance.
