after 4 and 1/2 years, my bottom module is dying. People hear a hollow sound when I talk to them. I did test the primary microphone through the Check Up app. Yes, it sounds hollow and very distant.
I am looking for a working second hand bottom module. I hope I get lucky and find one here.
I already did ask the Fairphone Angels in my city, but they do not have one. Anyone, ideally in Bavaria, Germany got a bottom module for me?
