When we drop tested Motorola's shatterproof Droid Turbo 2 we needed another phone to demo how devastating a four foot drop onto granite is. We chose the non-shatterproof Droid Maxx 2 believing that on the first drop it would shatter and the screen would explode a spider web of cracks
Try as we did, the Maxx 2 screen didn't shatter. See the video of the Maxx 2 bouncing down concrete stairs.
