If the microphone doesn't work in GSM calls but works in SKYPE or other applications, it is 100% the audio compiler that needs to be reballed. Reballing the audio compiler should only be done by a professional with a lot of experience. In the same area as the audio compiler is the touch ic, wifi module and the cpu is on the back side. If you use too much heat, you can damage one or all of those components. If you live in Europe, we have a 100% success rate with reballing or sometimes replacing the audio compiler.
