FAQ
Common questions before you start testing
Does MicTests.org upload my camera or microphone data?
No. The core testing flow is designed to run locally in the browser, so streams stay on-device during the check.
Why do I need to allow browser permissions?
Modern browsers block microphone and camera access by default. The page can only test your device after you approve that request.
Why can a device look connected but still fail the test?
A device can be connected but muted, selected as the wrong source, occupied by another app, or blocked by operating-system privacy settings.
Ready To Check Your Setup?

The microphone flow is the primary entry point for MicTests.org and the strongest match for urgent pre-call troubleshooting.
