My microphone doesn't work after screen replacement.
I replaced my screen on my GSM/AT&T iPhone 4. All other phone features work great, except for when I'm in a call, and the phones speakerphone feature is active, the caller cannot hear me. I've cleaned the noise canceling port next to the headphone jack, and I've ensured all connectors are tight. I can record my voice in a voice memo, and make calls just fine without using the speakerphone. I could use any assistance, I cannot figure this one out.
Thanks a lot everyone.
