I dropped my phone from a table that I was eating at outside onto cement. Other than a ding in the battery cover, it was fine.
My brother, who owns a Razr MAXX and has the Gorilla Glass, dropped his from about the same height and it spidered much like a windshield does.
So, it all depends on the phone like someone else who replied. No two are made the same. I did have a screen protector on my Rezound, but no case.
I love this phone though. Coming from a Droid X, I thought I might have been disappointed, but have been nothing but pleased.
The Dre Beats are awesome as well. I got my phone for $100 on Leap Day, so the Beats were like an added bonus since they retail for $100.
