Does anyone know of or have any recommendations for something I can use to protect the back glass? I've already got a front protector but would like some extra protection for the back, even though it's in a case. I just don't want something sneaking between the case and phone and cause any minor scratching. I plan to just get a skin from dskin for my S7 Edge (it's black and I don't mind covering it up) by my wife's S7 is gold and I'd like to find something clear for that one. I'm guessing I'll just have to get a full body protector and only use the back portion but I wanted to see if anyone else has done something similar. Thanks!
