What this test checks
How to use this test
Touch and drag across the pad, use several fingers together, and cover each cell in the grid.
What the results mean
Observed contacts and covered cells show which pointer events reached the browser.
Troubleshooting
Clean the screen, remove problematic protectors, avoid palm contact, and compare another browser.
Browser limitation
The browser reports observed contacts; it cannot guarantee the panel’s factory-rated touch capacity.
