Why won't my microphone work even after replacing charging board?
My Samsung S9 Plus SM- G965U took a hard hit and broke the rear glass and the microphone quit working. I had a shop replace the back and the charging port board, but the mic still does not work. I replaced that board with an aftermarket one I bought on the internet. It did not fix the mic issue. I bought a genuine Samsung board that came from a working phone and tried it. The mic still does not work. I was going to test the mic on a set of headphones, but now I also notice that the headphone jack does not work. Nothing happens when I plug in a set of headphones. I connected a set of bluetooth headphone and the mic works this way. All functions of the phone work, the screen is not damaged, sound works, touch works, fingerprint reader works, wifi works, sim card works and I can make calls and text if I use bluetooth. I have also factory reset the phone twice. Any suggestions would be appreciated.
