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.

No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
