Fixing the microphone issue
I am suffering the microphone issue and there is not official service in my country, so, Is there a way to fix the main microphone issue?
Testing and testing, as nothing else could be done, i was able to record my voice using the main mic. My guess is that it still works, but something is interfering with the sound entering the phone.
Should I open it? Why should I look? How is the process of unstucking the diaphragm of the mic (as I read in the google forums that it can be one of the causes).
Finally, I bought the Charging Port PCB, I replaced it and the mic works really nice again. The main mic is in that PCB, so I finally replaced my phone. :)
