Microphone is weird after update

[Cwleaf]

Hello.

Ever since I updated to Android 6.0.1 (Software version 23.5.A.0.570) I've been having problems with calls, people can't hear me very well unless I talk very loudly and slowly.

Bad sound when you talk.
Suggestion to out dust from the microphone
to make it better!?
