    Any fix for iPhone mic on speakerphone?

    I originally jailbroke my ip4 via jailbreakme.com. The mic never worked when on speakerphone (which is common from what I've read). Thought upgrading to 4.2 would fix (JB by greenpoison) it but I still can't use my speakerphone. Has anyone came up with a fix?

    Does it work when you restore to stock? Did you restore from backup or as new when you restored to 4.2? Take it in and replace it. Should be under warranty.

    I did an upgrade from 4.0 to 4.2.1. Then instantly did the JB so not sure if it worked stock. But from what I read, a lot of people had this issue when using jailbreakme. I assumed upgrading to 4.2 would fix it but I was wrong. I'm would think it's a software issue since it happened with the JB and seems to be common.

    I've never heard of this so not sure it's common at all.
    Maybe you've read some threads that you think had this problem but there are lots of threads asking why the second speaker doesn't work... which is funny because there is only 1 speaker.
    Plus, the jailbreak is a universal thing not different for all people. If it was the jailbreak then everyone would have this issue and it would be really weird because there are different jailbreaks.

    Nope, you can not say it happened with the jailbreak at all.
    Sounds like you are restoring from backup which is your problem. backup your stuff another way (there are other ways more cumbersome) and Setup as new phone. If it's not that then it's hardware.
    You said you upgraded, did you hit upgrade? I'd press restore. Always restore to new firmware.

    I did a Google search for the problem and found a few articles about it so it sounded rather common to me. But I could be wrong. Anyway, it's the MIC, not the speaker. The mic works fine during normal conversations but shuts off during during speakerphone. I can hear them...they can't hear me; AT ALL.

    I'll try and do a full restore and report back with an update. Though I'm not sure I use the speakerphone enough to justify all the trouble.

    ^Did you install any of the VolumeBoost scripts from Cydia? Those mess with the gain settings of various modular audio components. If so, try removing the script and respring.

    I don't think I have anything audio related (other than some ring and SMS tones). I really don't have that many Cydia apps on my phone. But I would have a hard time not having Lock Info or I Real SMS notifications.

    on the top left of the iphone 4, there is a hole there that is a secondary mic, is that covered by invisible shield or a cover? If so, try removing it and see if they can hear you on speaker.

    Looks like this..

    i did a google search for that pic above and read more down and it basically said the same thing..

    the secondary mic is for noise cancellation and if it thinks its noise, it will cancel out your sound..

    I always wondered what that little hole was. Nothing is covering mine but maybe it isn't working. Looked for an app that could disable it (just to see) but no luck.
