Ultra mic stopped working

[Grahambell]

The microphone on my 1 year old Droid Ultra suddenly stopped working for calls (including speakerphone), voice memos (records only static), voice to text, and all voice functions except the video recorder. That works fine. Bluetooth and wired microphones work fine for calls. I've tried restarting the phone, removing recently installed apps, and clearing the cache of running apps. Any ideas how to fix this?

Have you checked to make sure there is no lint or dust blocking the mic port? Also, try booting the phone into Safe Mode and see if the mic works then. If it does, then the problem is probably software related. If it still doesn't work in Safe Mode, it may be a hardware failure.

Definitely agree...and make sure debris isn't blocking the port...gently blow into it..don't use compressed air...its over kill here..
