Mic randomly stops working during calls, even with earbuds.
Last night my girlfiend dropped her iPhone 4. The screen is smashed, and I will take care of that as soon as the repair components get here. The touchscreen works so I was going to let her use the phone even if cracked.
The problem is her mic stop working during calls, che can hear me but her voice is gone. If she shakes the phone a little the audio comes back, and stays on if the phone is kept on a still surface.
My first suspect was on the ambient mic shorting or something like that, I know it's a common issue. So I tried to turn on the Hear Aid option under accessibility which was supposed to fix the problem but no luck, her voice still fades away at times.
Still that seems the thing since Facetime works correctly and so do video and sound recording.
I tried the "cardboard fix" that solved the problem for many but that only slightly improves the situation.
The problem is I'm not sure how to deal with this since the Hear Aid option was SUPPOSED to work...any ideas? I'm quite desperate at this point.
That rules out the audio ic chip
Next troubleshoot will be to change the accual mic that's in the dock connecter.
So a new charging port will he needed..
When using FaceTime and voice memos it uses the top mic that is attached to the power flex..
When she's on a call can people hear her when on loud speaker cause when on loud speaker it uses top mic..
Bottom mic when on normal call
