IPhone 4S microphone repair?
I recently dropped my iPhone 4S gsm and cracked both the front screen and battery cover. I ordered new parts and installed them. Everything worked perfectly until I placed a call and the other person could not hear me. I recorded a voice memo and all it picked up was a static knocking noise. If I blew into it, it would record but very muffled.
I ordered a new dock assembly charger port with a new microphone and replaced it hoping it would fix the mic problem but the problem is still there.
The mic in calls does not work
Siri does not work
Voice memo does not work
However the audio when I record a video does work.
What should I try now?
