Hi everyone - Has anyone had any issues exchanging their iPhone 6s in the Apple Store? I have the Space Gray model with several noticeable dust specks behind the screen (I know, OCD) and I'd like to exchange it for the white/silver model. Would I need to make a genius bar appointment? I only ask because the Apple Store in my neighborhood has been a complete madhouse this week with lines of people outside, etc. Any advice would be appreciated.
