Microphone not working

[iain_h]

Just lately the microphone on my Lumia 720 has ceased to work, making voice calling impossible. I can hear the caller but they can't hear me.

Obviously this state of affairs can't continue.
Has any other 720 owner had this problem? If so, did/ would a factory re-set help? I don't really want to go to the trouble of sending it away for repair and then having to re-install all my apps when I get it back.

If you are still under warranty/insurance, you're going to have to do a factory reset before they'll cover a repair or replacement. The reason for this is that software corruption can cause many things that can appear to be hardware, but aren't, and since software problems are not covered, they'll want to prove it isn't software that's the problem before they do a replacement or repair. It's pretty standard in the industry. Save yourself the time on the phone and back up all your pictures and music, and do the factory reset. If it solves the problem, you've got a good phone again. If it doesn't, you know it's hardware and can get the phone fixed or replaced.

If you don't have warranty or insurance coverage, that still applies, because if the reset fixes it, you got the fix without spending any money. It just makes sense to do it.

So, looks like im another "victim" .
I send my Lumia 720 to warranty and they also changed the microphone, today i got my telepohne back and guess what? Nothing changed.
People who i am talking with can't understand me and they're saying that im underwater or something...
I found something weird about it - when i change to speaker and then back to default my voice quality is a little better but not much.
Is this a problem with 2nd microphone? im really annoyed about this because i can't use the most important "feature" of phone, lol.

Sorry for bad english, hope you understand me...

My microphone seaced working af few days ago, i hoped it just would start working after restarting but it didn't. In another forum (Lumia 925) a person plugged af headfone in an after unplugging the micophone worked again. So I tried with a headset from a MP3 player, but it didn't Work.
Then I plugged in the headset, turned off the phone and rebooted with the headset still in place. And now it works fine again! I just hope it will last...... But it's certanly a software problem. I hope this simple solution will work on your phone too.
