Applications on my S21 do not pick up sound from microphone. When I try to record audio in sound recorder, or voice message in messenger, or search with google assistant - applications behave like everything works, but there is no sound transmitted to the application. Voice message is recorded silent, voice recording in recording app is silent, and voice search behaves like I am not saying anything. I see green dot indicating that microphone is being accessed, in microphone access logs I see all apps accessing microphone. Microphone does not work with bluetooth headset.
Everything works in calls, and in camera for video. Even more, when I call through messengers - everything works fine as well.
Of course, all permissions are granted for apps. I also tried Wipe Cache via recovery boot.
I did not try factory reset (and I do not want to).
I am having same issue
Did you find a solution? My phone just started doing this
Yes - I threw my phone away and bought Iphone. Never will buy any Android again in my life.
Same exact issue here.... not sure if it is related to latest Android update... I am also having issues with fingerprint reader
I replaced my SIM card reader, microphone, and charging port board. Fixed my issues. A relatively inexpensive part too
@Rick13h: To troubleshoot the issue, please try pressing the Volume Down and Power buttons together for around 10 seconds until your phone restarts. This will simply refresh the device, and will not affect your personal data or settings.
Following the restart, please head to Settings > Apps > Voice Recorder (as an example) > Permissions, and make sure that 'Microphone' is allowed. If you then open the Voice Recorder app, tap the red circle at the bottom of the screen, and record a short voice sample, are you able to hear yourself in the resulting file?
If not, please open the Samsung Members app > Support > Diagnostics > Mic, and follow the on screen prompts. Can you hear yourself during the playback?
That did not help. Voice recorder records silence.
