Nokia 1520 Microphone problems

I'm on my second 1520. My first one had this issue along with an issue with the camera going all wonky. It also would get really hot while not being used and when I would wake and unlock it. It would say "Resuming" or "Loading" and take forever to bring up the home screen. Resets did nothing to help, so I had to get a replacement. Number two is doing the "Resuming" thing and now the mic has stopped working. I had high hopes for this phone and paid a lot of money for it only to be let down again. I'm a Microsoft fan and would never buy crApple. But I may be looking into a Samsung or other Droid phone.

Hi have the same problem. i have now purchased 6 nokia 1520 phones each of which has failed in the same way. Basically if i ever connect a phone to a bluetooth device the internal mic gets redirected to the bluetooth and after that there is nothing (other getting it replaced) you can do return it to the internal mic. No resetting or firmware changes fix it.

i have a second fault which is caused if i ever place a mic/headset in the 3.5mm jack socket, again the issue is the loss of the internal mic.

In both cases the only way to make calls and be heard is to use the hands free speaker mode.

This issue is reported everywhere, my phones were purchased at different times, from different places in the world, all have failed even when i have not directly connected to a bluetooth headset ie just connecting to another bluetooth device causes it.

Really had enough of this one, i am a developer on the technical preview platform causing me real issues in writing phone apps

Amazing. In the last 10 months have connected my 1520 to over half a dozen bluetooth devices and wired speakers and headsets with absolutely no mic issues whatsoever. I must be incredibly lucky in that respect.

Yeah, this problem is getting annoying. It went away for one day and came right back without any indication as to what caused it. Unfortunately I have an unlocked international 1520 (rm-938) here in the US. Ive already had few folks run into the predicament of Nokia US not wanting to repair their phone because its an international version being used in the US. Nokia/Microsoft, do something! I have tons of Nokia products, but this one has turned me off the most. And impair the most for it out of all my phones.

I'm having the same problems with the mic since updating to denim so convinced its a software problem. Are there any other software solutions out there short of dumping denim?
