Microphone test: record and play back

If people can't hear you on calls, this test settles in one minute whether your microphone is the problem – with a live level meter and a sample recording.

Reading the result

Bar doesn't move: no signal from the microphone. First check the browser permission (icon in the address bar) and whether another app is holding the microphone. If it still doesn't move, a hardware fault or a fully clogged mic opening is likely.

Recording quiet or muffled: the microphone opening – a tiny hole on the bottom edge – is probably blocked by dust, lint or a badly fitting case. Screen protectors covering the opening happen too.

Crackling or dropouts: points to a loose connection or moisture damage, especially if it started after a drop or water contact.

Several microphones, several symptoms

Modern phones have two to four microphones: bottom for calls, top or rear for video and noise cancellation. That's why callers may not hear you while video recordings sound fine – or the other way around. This browser test uses the system's default microphone; complement it with a practical check: a voice memo (bottom mic) and a short video (top/rear mic).

Cleaning and repair

Clean the mic opening only with a soft dry brush – never with needles, toothpicks or compressed air; the delicate membrane sits directly behind it. If that doesn't help and the test still fails, it's a repair-shop job; depending on the design, the microphone is replaceable individually or as part of the charging-port module.
