Touchscreen Tests
Map touchscreen response areas and measure simultaneous touch points with pointer and touch-capable browser APIs.
What these touchscreen tests cover
Touchscreen diagnostics listen specifically for touch pointers so a desktop mouse cannot create a false pass. Grid coverage checks response across the panel while multi-touch tracks simultaneous fingers.
When to use these tests
Use them when part of a phone, tablet or touch laptop stops responding, after screen replacement, or when you want to check how many simultaneous touches the browser detects.
Tips for more consistent results
Test directly on the touchscreen with clean, dry fingers and repeat any suspicious area. A single missed grid cell is less meaningful than a consistently unresponsive physical region.
