today my FP3+ shut down because of too cold temperature at the battery (at least I think that the screen showed this message before turning off). After a reboot I have several problems with my FP3+.
I cannot hear nor be heard by another caller and when using apps (tested with YouTube, Audible and Spotify) there is no sound.
The service tests for microphone and earphone failed. The service test for speaker was successful. I can also hear the caller when turning on the speaker.
What can I do?
Thanks in advance.
