So I have two sets of BestSkinsEver full body protection for my 6+ of which one is the matte case friendly set. Prior to applying them, I would like to know if I can still install cases without tearing or peeling the skin. My second set is the conventional version but the one with the bottom skin that folds up to the sides of the phone. It would be great if I could find out know so I won't end up wasting the skin. So far, I have the Spigen Air Cushion with the Zagg Screen Protector but I recently purchased the Rock (.08) and Speck CandyShell Grip Case. Thank you in advance.
