    I had my iPhone 4 front LCD screen replaced as it was broken. After the replacement, speaker and microphone are working fine individually but when I make a call and turn on the speaker the person on the other end cannot hear me. They can hear me if I turn off the speaker and talk normally.

    Can someone help me fixing this?

    Exact same problem. Restored twice so it's definitely a hardware problem. Can't swap out. Repair it is...

    I had my iPhone 4 front LCD screen replaced. Since than, I've been having the same problem with the mic when speakerphone mode is on. Also i realized that no sound is recorded when I record a video using the camera.

    are you guys doing the repair yourself or at a shop? cause it sounds as if someone really didnt know what they were doing. I have had bad parts come in but never this issue so it sounds as if something wasnt put back together correctly.

    Well I had mine replaced yesterday morning at a cell shop ! My friend replaced his iPhone screen at the same place last week and everything is work great !
    The only difference is that I got my screen replaced PLUS I asked the guy to fix the power/lock button , it has been broken for over 6 months ! Before yesterday everything was working perfectly !
