Hi all, I realised my P30 Pro’s bottom microphone stopped working. All apps that use this (Shazam, Google) pick up no sound from it. If I’m on a call, i have to wait between 5-10 seconds (which I think is when the top mic kicks in), then person can hear me. I have factory reset, cleared all caches but no luck so going to attempt changing the microphone/ SIM board. Has anyone done this before with success? On eb@y there are some boards that have this little silver IC in the middle of the board, and some don’t (this is on the opposites side of the SIM slot). Does anyone know what that is?
