Have a look here : No sound 50+% of the time in calls, until reboot - #174 by Bas_tien
That concerns the problem where there’s no sound during phone calls.
There’s also that topic : Group action against Fairphone for dishonest support on Fairphone 3
Where I hope gather information about forcing Fairphone to respect the consumer law and provide a honest support

I noticed that my microphone stops working for audio and video recordings after I have used my FP3 in my car. Problem can be solved by restarting the phone, but it is very annoying. Is there any way to fix this problem in the settings?
As this topic is about Android 10, are you still on Android 10?
No, my mistake. I will post it in an Android 11 topic. Thanks for the feedback.
