Since two days ago I can’t hear people calling me (they can hear me) and there is also no sound when I try to play music or videos. But, on the other hand, my alarm clock and ringtone still work fine, which suggests, that the microphone is not broken.
When I connect the phone to a headset I can hear the caller and also play music like normal.
I have updated the phone, restarted it and removed and reentered the SIM-card, none of this seemed to help.
Are there different microphones used for these different “features” and maybe one of them is broken or does anybody have other suggestions about what I could do?
