Phone Motion sensor test
Enable sensor access, set the phone still, then gently tilt it. Watch whether the available readings change.
Instructions
Availability depends on the browser and device. Readings do not verify sensor calibration or the phone’s auto-rotate setting.
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.
