since a couple of weeks I’m having problems with calls on my fairphone 3. When I get a call it notifies me and I can accept the call, but neither can I hear my partner nor can he hear me. Same issue when I’m initiating the call and on both sim cards (Vodafone, Telekom).
For other things (e.g. create and hear voice messages) the mic and speaker work, so there’s nothing wrong with them.
When the problem occurs I can solve it by restarting the phone. After some hours or days same issue again.
Wifi-Calling is disabled for both sim cards
Thanks a lot for any answers!
