I don't know what functionality you think it affects?I don't understand the love for otterbox cases. Why put a case on a phone that so badly affects the functionality of it? There's better cheaper cases
Mine works and functions the same with or without the case.
However, I'd like to see a phone survive getting run over or dropped, without the case, like mine have.
It costs better than 100 bucks to replace a broken screen, at the phone repair place. An otterbox costs me less than 75 bucks. It lasts the life of the phone. I have known several people to replace broken screen several times (E.G. 3-4 times) before getting a new phone.
People can be tough on their tools. I am one of them.
