Replaced screen and people cant hear me during phone calls, also echos
Alright, Guys, I need your help! I have replaced the LCD screen of a customer and everything works perfectly, besides the microphone. During phone calls, I can hear everything, but they cant hear me on the phone. When I turn it on speaker I can hear them, but there is a big echo. I then replaced the LCD screen with a phone that I knew that was working. This fixed the issue, but now the other phone is having the same issue. So I believe the issue is coming from the screen, but I am not sure. Can anyone help me out, please?
Is this a good question?
