Dropped mine 2 times.
1- Dropped it from around 6ft last week with no case, just some scratches in the top of the phone. Was on a shelf, was making up with my GF, one thing led to another... it was worth it, when I came back for my phone I almost had a heart attack when I saw it laying on the floor with the screen facing the floor.
2- Broke up with my GF and she did throw my phone pretty hard to the floor from around 4.5 ft, it had cheap hard case on, it opened up when it hit the floor and bounced a few times.
Case is totally destroyed, with a ton of scratches and in the corner it broke totally, its looks like someone hit it with a hammer. Got a scratch on the top left corner of my black 1520
Having a GF can be pretty bad for your 1520, but after 30 seconds with nail buffer/file it looks almost like brand new. It's HARD to see the scratches that are left, I'm sure I can get rid of them with care.
EDIT: Both times were on concrete!
