Webcam test
Preview your camera and inspect its negotiated resolution and frame delivery.
Diagnostic visuals retain their original colors and remain visible. Presentation filters and high contrast apply outside this workspace; device-level filters may still affect your observation.
Allow camera access, inspect the preview, and try another camera or front/rear mode.

How to run this check
Allow camera access, inspect the preview, and try another camera or front/rear mode.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Track settings describe the negotiated video stream, not the sensor maximum. Frame delivery is estimated.
If something seems wrong
Close other camera apps, uncover the lens, check system permissions, then retry.

Is anything uploaded?
Raw diagnostic input and media are processed locally. Standalone results remain in page memory. Guided checks offer optional coarse session recovery for 24 hours; it excludes media and detailed measurements. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.
Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
