after the breaking of the switch power button I proceeded to replace the flat. After putting everything I have, however, found that the hands-free microphone is not functioning.
I disassembled everything again, double checked but it seems to be all right (power button and proximity sensor are ok)
I can not understand what could have gone wrong.
I should add that the hands-free microphone with the old flat was working at 100%.
I have already ordered a new flat, because maybe what I have mounted is defective ... I doubt it but I hope so!
Does anyone have ideas or suggestions?
