I still have the back plastic it came with on lol.
I wonder why there is no sound?
I can wave my hand over the phone with sharp objects as well.
The one on diaplay at tmobile was scratched to hell.. just saying.
True, but I doubt they are carried open with the blade exposed (at least not intentionally). Which leads me to a question for OP: Did you do the test with the sharp, exposed corner of the box cutter, or just the edge of the sheath? It's kind of hard to tell from the video.
Also, gotta agree with your comment from the video: 0:27 - "I like 'em naked." Do you feel like you still have that "naked" feel with the bumper on?
Haha this is bullsh*t... Try scratching with a needle, or something very sharp and pointy. Of you vont scratch it with a key... Even my old sgs can take that.
There's no sound because there's no scratching. You need friction to hear the sound. The gorilla glass is harder than keys, boxcutter, coins so those things just glide across the surface. The only sound you hear is the impact from first contact... scratching motion just glides across the surface.I wonder why there is no sound?

I was under the impression most scratches on screens these days were caused by grit/sand lying dormant in the pocket waiting to strike an unsuspecting naked phone screen. Rather than something large like keys or a flick knife or a frikin gun.
I don't keep my phone in my pocket with anything else just incase and yet there is still a tiny scratch on my GNexus.
Are you sure it was scratched and not just in need of a decent clean from all the greasy fingered children? I can't imagine a display phone being subjected to objects that would scratch a phone normally in a display environment. Unless someone has specifically attacked it to test it or the TMobile staff were using it for football practice?
Lots of folks are worried about the Nexus 4 glass screens. In case you guys were curious, here's my newly delivered Nexus 4 (both front and back) vs boxcutter, keys, coins, wrench.
