IPhone 4 microphone not working in phone calls but working in other apps

iphonemicrophone

People cannot hear me when I make a normal phone call. When I use Skype or Facebook call it works but not during a normal call.
I have done a phone reset already but didn't work
Any ideas?

Best Answer

2 mics

You have 2 microphones on your iPhone:

  1. One for normal calls, this one is broken in your case
  2. One for environment sounds. This one is used for video conference calls, video's, sound recordings. This one still works.

My suggestion is to go to iFixit and replace your dock connecter. This replacement also fixes your mic.
