I'm clumsy! Looking for a new, robust iPhone case for my fictional new iPhone. Currently have a case like a book which also covers the front of my phone. Most of the cases for the new phones seem to be ones which protect the side and back but not the screen. Are the new screens so robust they don't need protecting and won't get scratched when e.g. in a backpack or handbag? What type and brand of case have you got and do you recommend it?
