How to Fix a Samsung Microphone That Is Not Working
If people cannot hear you on calls or recordings, the problem may come from dust, a case, Bluetooth routing, or a faulty microphone.
Quick answer
Clean the mic area, disconnect Bluetooth, and test voice recording in more than one app before assuming hardware failure.
Steps to fix it
- Clean the microphone opening gently and remove any case that may block it.
- Turn off Bluetooth so audio is not being sent to another device.
- Test the mic in Voice Recorder, a phone call, and a video app to compare results.
- Check microphone permissions for the affected app and restart the phone.
What to check next
- A phone can have more than one microphone, so one function may fail while another still works.
- Lint and water exposure often cause muffled or weak input.
- If only one app has the problem, fix that app first.
