Touch test
Slowly sweep your finger across the grid. Try two or more fingers together and watch the contact count.
Instructions
Empty tiles are untested areas, not proof of damage. System gestures and the browser can interrupt touch input.
Use an up-to-date mobile browser: Chrome, Safari, Samsung Internet, Firefox or Edge. If opened inside another app, open this link in your regular browser. Feature availability varies; unsupported is not a failed test.
Your phone check report
Working results are confirmed by you. Unsupported or skipped checks are not failures. This is an observation report, not a hardware certification.
