For some time my microphone is extremely quiet when doing things like making voice messages on whatsapp or when calling someone. I searched the internet for a solution but couldn't find anything except for some apps which didn't work (or only worked in the app itself but outside did nothing). Is there a config file with the microphone volume so I can adjust it myself or some script or so?
Wired headset microphone is also extremely quiet.
Information that could be relevant to this problem:
Samsung G900f (S5)
Android 6.0.1 / Cyanogenmod 13
Baseband version G900FXXU1BOD3
