So i need a good protective case. The outterbox defender seems to fit the bill. But i have mixed feelings about it. I have read a few reviews about the screen protector bulges up in the middle of t screen. Any way to fix this? Or is it really not that bad? The button slop i could maybe deal with because my current hone has the same problem with the volume rocker and its an outterbox commuter case. But what i really want to know, does that bulge in the protector make it unusable? meaning when you press y on the keyboard it presses u? Or any variation of that. I don't want to buy the commuter really because i will be working outside a lot wit it, and the defender has a clip on to which will be handy for that.
