Checking your mics

[maverick786us]

Lumia 930 and 1520 have 4 microphones for rich HD audio recording. 2 in front and 2 in rare. My Lumia 930 just came from a service center where its entire screen and the frame were replaced. Now replacing screen is a task which requires a lot of precautions, where a slight lack of concentration can affect other circuits.

Is there a way I can find out, if all the 4 microphones are functioning properly? For example if one microphone from rear or front goes, it will still record and you can still talk. How can I check if all the 4 microphones are functioning properly?

check ''nokia care suite 5'' in computer, surely the phone tests in that will indicate if microphones are functional.
