Hello,
I’ve been having an issue with my microphone for a long time. I commented with the technical service and they only recommended send it for repairing, but before doing that, luckily, thanks to a FAIRPHONE ANGEL, I did some tests on my own and found the problem. So, I want to share it here, in case is useful to anyone.
I think this might apply to any version of FAIRPHONE.
My particular problem was: the microphone stopped functioning randomly, but only the option of recording (meaning, recording in whatsapp, voice recorder, and also the video in the camera, or the Google dictation), however, phone calls worked perfectly fine. When this happened, I had to restart my phone and everything worked again for a while. But then, it happened again.
Well, what I did was: first, restart my phone after one of those moments where mic was failing, and just let it charge during the night. Next morning was still working, so it was not something just happening with the time. So, then, I started uninstalling apps that use mic, one by one and testing mic before and after unstalling, so there we go!: IT WAS ALL ZOOM APP FAULT.
Once I uninstalled Zoom, everything else (I checked all the apps) was working, until, again, I reinstalled Zoom.
I have no idea about Why, and now I cannot use Zoom in my phone which is a bit annoyiing because I use it frequently. But at least I found the problem and now I won’t need to be restarting my phone every other time.
I hope this is useful for someone. If your mic is not working and you want to avoid send it for repair or fabric restart deleting everything, be patient and try your apps, one by one.
Cheers
