I had the pleasure of talking with a Samsung rep at the Verizon store the other day. I asked about the durability of the phone because she said the flip is the only case they recommend. She was throwing it all around the store from up to about 6' high. It would explode the case and battery off the phone and she explained that they are designed to do that to release the pressure from the screen on impact. And that with a lot of the cases that keep the phone together can actually cause damage to the screen. Now I did ask her to show me on the sidewalk outside and she gave me that look like you know I can't do that. My personal opinion is that it's all in the way it drops. I have sent my thunderbolt flying across the room by trying to use my foot to break the phones fall. Nothing happened to it. But my last phone in my pocket cracked. Luck of the draw really.
