My theory is that the piece of manila folder put just enough pressure on the internal components so that I did not have to manually do it.ĭISCLAIMER: This is just my fix. I pre-cut a piece of manila folder about one square inch, and layed it inside the back bottom right, and put the back glass back on. I unscrewed the bottom two screws and removed the back glass. Putting pressure back on, they can hear me. Sure enough, not one could hear me unless I pressed the right bottom of the ihone 4. While testing (facing the back glass), I made calls and put pressure on the left and right sides of the bottom of the iPhone 4.

Put pressuse on left or right bottom corners of iPhone 4. In/Out calls work for a few seconds, then callers can't hear me all of a sudden.Īll other applications that use the iPhone microphone work, yet phone app on does not.

SYMPTOMS (With Microphone, Ear Buds, or Bluetooth): I scoured the Internet for a fix, and I've found a few hints that narrowed my problem down.
