As fairphone angel (in Berlin) I have a lot of support cases with nonfunctional microphones in the bottom modul. A lot of users have minimum the 2nd, often the 3rd bottom module. Mostly easily changed by Fairphone support in warranty.
But there is a lot of waste (I collect old faulty modules and send them back for recycling).
So my questions:
- Did anyone successfully repaired the microphone inside the bottom module by soldering a new smd microphone?
- What’s the reason for the highly rate of faulty microphones? I first expected just dirt inside the microphone (like a lot of faulty headphone jack problems are just dirt/lint stuck inside). But I opened some of the faulty bottom modules and everything seemed clean. So it’s just bad smd module with low quality?
My search results:
- The user @userr tried this in the closed thread FP2 Bottom Module: Repair broken µUSB port but without feedback
OT: I opened this thread (at first as question), but in future it could be a wiki entry to collect all information about repairing the microphone
