microphone not working after change of screen

Replace the dock connector mic assembly. Trust me I do this for a living.

You do have to remove the mic/speaker assembly to change the glass. There are 2 screws under it that hold the front glass on. The top noise cancelling mic works on apps voice memos and speakerphone. The bottom mic is attached to the dock connector and works when the phone is up to your ear.

Ic audio broken

I'm having this problem with many phones recently, can't understand it?

Try this has worked a few times for me..

If mic doesn't work when on a call and you can't hear them also this is the fix

My iphone has had problems with the noise cancelation mic, does anyone know how to fix the problem... I have iphone 4s

Okay my iphone 4 had a smashed screen so i bought another and changed it, everything was good until someone rang me and they said they could not hear me?? but i could hear them, but they could hear me when on loud speaker?

is there anything i could try to resolve the problem or is it a bin job?

thanks inadvance
