HELP!! Iphone 4S microphone has stopped working?

[Herr Flick]

Been working fine up until about 15 minutes ago. Just had two people call me and they couldn't hear me, put the speaker phone on and they can hear me fine.

Rang them back and they couln't hear me, speaker and they can!

What is all that about??

Anybody had this problem?

Backup, Restore.

If not, take it back to apple. Its still in warranty.

At work at the moment and really need the phone to work as i'm always on it.

Check if water damaged... replacement parts are easy to get hold of and easy to fit

I had this problem on my 4 and ended up messing about with hearing aid mode which fixed it.
Might be worth googling it?

The only thing you can do now is reset (both buttons held) , and i imagine you did that.

Just use the speaker until you can get to Apple?
