Problem: my cellphone, a Samsung Galaxy Note, had sheer plastic curved sides that were hard to grip properly. I kept worrying that it would slip out of my hand and smash on the ground. (I tried a silicone case, but it was too bulky and made the phone's back too grippy to easily take out of my pocket.)



Solution: I only hold the phone by two points: the sides at the middle. If these had grip, I wouldn't risk dropping my phone and I'd avoid the bulk of a full case.
