I cannot be heard during calls

Hey there. So for some reason my phone isn't picking up my voice on calls alone. The voice recorder picks it up fine, but during calls I can't be heard at all. I can hear the other party during the call just fine too.

Answer this question I have this problem too

Is this a good question?

Hi @tartaurus ,

Use a magnifying glass and a strong light and inspect the voice inlet hole found on the bottom edge of the phone to check if it is blocked with lint or other debris.

It is is (or even if you can’t tell), try using a vacuum cleaner to see if you can clear the obstruction.

DO NOT use a pin or probe to try and clear it as you may damage the microphone which is directly behind the inlet.

If this doesn’t resolve the problem, try using the earphones with the microphone attachment when making or receiving a call. If you can be heard OK when using this, then this proves that the voice transmission circuitry of the phone is OK and that there is a problem with the internal microphone. It is either faulty or has come loose from the systemboard.

That's just the thing. The mic works fine on everything else. Recording videos, recording audio. Both pick my voice up fine. It's just during calls.


Hi @tartaurus ,

Like a lot of Android phones there are 2 microphones in the phone. One is used for "normal" mode phone calls and the other for "speakerphone" mode or similar type usage where the phone is held away from the face.

Still worth a check ;-)
