"Try cleaning out the doc connector, head phone socet and the little tiny hole next to the head phone socket.
I found that a paper clip was a useful tool for the job.
After clearing out all the fluff and dirt from these areas. Gradually the microphone started to again for me.
I couldn't talk on phone without speaker phone active or headphones plugged in. I couldn't record voice messages. It's happened twice to me and both times this has corrected the issue for me.
I tested by making a voice recording and then called my 2nd phone to test calls were working as expected.
microphone doesn't work. The people I'm calling to can not hear me. When I place it on speaker, they do hear me.
Voice recording also does not work !
I've replaced the dock connector but the problem did not disappear. To be sure I didn't install a faulty microphone, I installed a 3rd one, but still the problem was not solved.
"My problem is the exact opposite...speaker phone doesn't work! I can hold the phone to my head and makes call with no problems. I cannot use Voice Recognition to compose text messages, but the Voice Memo via text DOES work...
Which microphones control which functions?? This seams like a software issue to me, not a hardware issue. I just did an update, and this crap happens, thanks APPLE!!"
