I am estimating it was roughly four feet, give or take a few inches. I went to grab it off the surface, and wow this phone is very slipped naked. It slipped right of my hands in the worst possible fashion. Screen first driving right into the ground horizontally. Battery cover pops off and flies at least a foot or so away, and the battery pops out and goes the same direction. I didn't even want to pick the phone up at first, I just kind of stared down in amazement at my own stupidity for taking my otterbox off due to bulkiness moments before. I pick it up, flip it over and to my surprise no crack on the screen. I was really expecting the screen to be cracked. This was on concrete flooring as well. Fortified glass FTW.
