Hi, I just got a new Iphone and it seems the mic is not functioning during calls or using voice memos. It does work, however, when I switch on the speaker phone.

I tried restarting and restoring using the latest os and it still doesnt work.

I sent it back to the carrier where I bought the phone. They had me pick it up the next day saying they just restored it - I assume he meant hard reset. I tested it and it worked fine.

The problem came back after I synced it with my mac - (i cant recall what version is my itunes), setting it up as new Iphone but with the same name - I assume this means restoring my old backup since I saw my data back in the phone after syncing - ie. notes.

What do you think guys? I read in the other threads that most just had it replaced - but this doesnt look like a hardware problem since the mic did work. Maybe Itunes is the culprit? (replacement takes a while from where I live).

    Sounds like your problem is related to corruption in your iPhone backup, thus restoring from that backup merely restores the problem. Try restoring your phone as a new device, not from backup. Follow that by syncing your content back to your phone. If your problem disappears, you've got your answer. Then go to iTunes>Preferences>Devices(under the edit menu if using Windows) and delete any and all iPhone backups listed.

    if that doesn't work, make an appointment At your nearest apple store and get it replaced under warranty.

    IF you have tried setting the phone up as a new device and the problem is persistent? You also mentioned the mic seems to work when you use the speaker mode. Have you checked to make sure : 1 There is nothing blocking the mic?
    2 If you have a case on the phone, try without a case 3 The plastic screen protector that comes with the phone.
    Normally after trying as set up as new device, if that doesnt work, that normally would point to a HW problem on the phone, make sure you have tried everything first of all ( Which it looks like you have). Otherwise book into a Genius Appt or phone AppleCare. =)
