I've had my nuud on my i6 for a couple days now. Love it. Looks great!
There are no issues with callers hearing me or me hearing them. I used the navigation today and no issues with sound on that either. Previously had a fre on my phone but wanted to have the screen access. The only con so far is difficulty with accessing the control panel swiping up on home screen. Not a big deal for me.
I have a tempered glass screen protector on with no issues. I read loss of reviews about sound issues and almost didn't order - glad i did. Will order another when the color versions ship.
