I've got the same problem. The mic isn't working for crap (cortana, calls, etc.) It was after a rollback from w10preview
Had the exact same mic issue on my 1520 and after all the testing and software downgrading and reloading, it was still not working only for phone call. It took it to a local repair center and got the microphone changed for a $65 price tag. For me it was a hardware issue... Phone works like a charm since then...
This is what I'm going to have to try.
If I cover the other two mic's (at the top of the phone front and rear - making them redundant) and make a voice note in messenger it records perfectly. Even if I whisper closely to the mic. So this must be recording through the main mic.
There is also an app called Hardware Tests by Amaze Pictures Inc in the store. I downloaded that today because it has a mic test feature. Again I covered the 2nd and 3rd mics. The test results from this app confirmed that the main mic works perfectly
According to this: Nokia Lumia 1520 Operating Instruction and Manual Book Download - Owner's Manual & User's Guide - PDF eBook Download and this: http://download.support.nokia.com/n...df/100000336184/Nokia_Lumia_1520_UG_en_US.pdf there are in fact 4 mics. They are listed as #12, #4, #17 and #22, in the diagram of the phone.
The only thing that I do not have is the blue frame (used in the video link provided Kha Bui above) to separate the phone body/screen. But looking on YouTube I see that others can do it quite easily on the 1520 without that frame. What do you use?
