Ever since my first smart phone, I never had a screen protector, nor a case. I know people may think that you've for a £500 phone, a £10 case and screen protector is the least you need to do, but I can't stand looking at a phone with a screen protector as the ones I have seen always seem to have bubbles, or dirt trapped, or start fraying like the plastic cover that comes on the phone anyway. Same with cases. My Nokia Lumia 920 has survived the occasional bump in my pocket. It stays in my pocket with nothing else (I don't understand those people who put keys in with their phone!). It doesn't stay in my back pocket and hasn't really been dropped, although has slid off the side of the sofa a couple times maybe. Certainly nothing on hard floor! Do I really need a screen protector or case?
