A:AnswerMy Samsung Edge 7 charges fine with my Speck candyshell on a cheap Qi wireless charger I picked up online. No issues at all, although I have heard from some that a case makes the phone notably hotter when wireless charging.
A:AnswerAs long as the artwork is on something extremely thin (paper, cardstock) and is no bigger than the area of the phone I don't think that would be an issue. The case fits very snug and is quite clear, but I'm sure there would be a small amount of distortion.
A:AnswerYou can use a screen protector ;but it will lift off eventually...because the case fits so tight...screen protector also decreases the sensitivity of edge functions.
