I did the sound test and they confirmed that one of the two microphone does not work. I can still speak on the phone but not on speaker mode nor if someone videocall me. I am currently based in Paris. Is there anyone who has a piece I could replace my Fairphone with? It is the iPhone 3rd. The guarantee is expired so I cant get support from Fairphone company.
Speaker mode uses the top mic, so you may want to get hold of a top module.
The Fairphone 3 top module includes an 8 megapixel front camera to make the best selfies. It also contains everything you need for clear calls, like the receiver, 3.5mm earphone jack, secondary microphone and proximity sensor. Fairphone 3 Top Module - 8MP front camera | Fairphone
thank you for your answer! I do not want to send my phone and be without a phone for possibly severals days/weeks as I dont have a back up phone. So I was wondering if buying the piece at FNAC in Paris was going to help? the microphone got broken a long time ago by someone who accidentally poured oil on my Fairphone. Nothing was damaged except this microphone to put speakers on / use during video call. thanks for your help everyone by the way!!
