    Mine is iPhone4.

    There are some different situations for mic. some works fine, but some fail.

    1. receive or make a phone call -> mic works.
    2. receive or make a phone call with speaker mode -> mic fails. (but I could hear the other side)
    3. audio recorder -> mic works.
    4. default build-in video recorder -> mic fails.
    5. only FiLMiC Pro could record video with sound SOMETIMES, not always. (other app I have tried -> mic fails)
    6. If I use mic of headphone, everything works.

    Speaker works normal for all situation.

    Any possible for this?

    How long has this been happening? Is it a recent issue?

    Have you tried resetting your iPhone? (slide to power off, press sleep/wake to power on again).

    Is your iPhone Jailbroken? If so there may be a software conflict and so you might want to consider removing the jailbreak.

    Lastley, you might want to try backing-up your iPhone and resetting it back to factory settings in iTunes, before reinstalling the OS again.

    Theses are the things I would look at if I had the same issues.

    Thanks for tour reply.

    It existed about one month longer.
    No JB. and iOS 5.1.

    I backup and reset data/setting to default. No luck. Mic still fails when record video.

    I know iPhone has two mic, maybe one of them is broken ?
