Check browser-visible phone motion by tilting your device and observing its response.
Allow motion access if asked. Hold the phone securely and tilt it slowly left and right. Watch whether the on-page indicator responds.
Browser motion observations do not isolate or certify every accelerometer and gyroscope. A blocked or unavailable sensor API stays unverified.
Motion permission may be required by your browser. Do not shake or drop the phone.
Results are saved only in this browser for up to 24 hours. This single test does not replace a complete used-phone inspection.
