S21 fe mic problem

[Gowrinandhan]

There is a problem with my s21 fe microphone. While recording some back noise is audible but the voice is very low that too audible when spoken loud. The problem is with both primary and secondary mic as well. 

There were no physical damages and it happened when I was in a call.

What could be the reason?
