Internal and headphones microphone not working but sound working fine
Hello I just got an iPhone 5S from a friend.
After changing the LCD and the battery the iPhone is working fine except the microphone is not working at all also with headphones connected the microphone of the headphones is not working but music comes out of the headphones.
I am not sure if this problem is a logicboard issue or if it is just the lightning connector.
How can I be sure which part is broken?
Is this a good question?
