My Nexus 4 was face down on my desk in a big puddle of water overnight. But it was in a rubber case, that elevated it a bit. The next day the microphone didn´t work any more and there was some discolored parts on the display. I let it dry in a bag of rice for 24 hours. The display went back to normal. Only the microphone doesn´t work ever since. If i do voice recording it only pics up static and tapping on it.
Is it possible to replace the microphone on the daugtherboard?
Thanks!
