mic doesn't work on phone calls but works otherwise
It looks like I need to replace a mic on my iPhone 4s, but it looks like there are 2 mics, and I want to buy and replace the correct part.
I cannot be heard on phone calls unless I use the speaker phone. The mic works for other apps. I need to know which part to replace, and I'm looking for a good video on replacing that part.
Is this a good question?
