So what do most smart people do after buying a new phone? They buy a case or bumper to ensure that the screen and/or glass back don't get destroyed the first time the damn thing falls out of your pocket.
Especially Samsung phones, which are made of the slipperiest substance this side of greased Teflon. (Love the phones, but yeah... I don't walk out of the store with one without a Seidio case/belt clip for it. Dang things practically jump out of my hands. Not a problem with a case made out of something that's not the mechanical friction equivalent of a superconductor. They ought to make bearings out of that stuff.)
