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
Angles may combine multiple sensors and reference frames. They are not a calibrated compass heading.
If something seems wrong
Allow motion access where prompted and compare a supported mobile browser.

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.
