Thanks for posting. That's pretty odd. May I know what troubleshooting steps have you done so far? I'm thinking if it's something to do with the microphone, could you please test the microphone on Device Help App > Fix > Hardware Test > Microphone. I would also suggest booting the phone into safe mode to see if we'll be able to replicate it. Let me know.
