Phone Microphone test
Record a short sentence, then play it back. Listen for clear speech, crackling or missing sound.
Instructions
Microphone permission is required. Audio stays in this tab and is discarded when you leave the test. Disconnect headsets to check the phone’s microphone.
Use an up-to-date mobile browser: Chrome, Safari, Samsung Internet, Firefox or Edge. If opened inside another app, open this link in your regular browser. Feature availability varies; unsupported is not a failed test.
Your phone check report
Working results are confirmed by you. Unsupported or skipped checks are not failures. This is an observation report, not a hardware certification.
