I've tried restarting in safe mode and still the problem persists. Just a lot of violent static on the other end and they can't hear a word I'm saying, but the static does seem to follow my cadence.
There has been no water damage that I'm aware of, and normal (non-speakerphone) works great. Is there actually a separate mic for the speakerphone?
I'm not sure how long after I installed Kitkat that this started happening and it may not be related. I just can't seem to figure it out.
Any suggestions? Thanks!
