As much as we're familiar with mobile device torture tests, they're normally inflicted by us or otherwise not-so-voluntary. Nokia, however, has stepped up to the plate and doled out the abuse to the Lumia 900 itself with a hammer and nail, all based on a wager that the Windows Phone's use of Gorilla Glass would hold up to Sonim-level punishment. The company's Chris Ruble and Mike Meyers (not that Mike Myers) used a Lumia 710 as a dry run before an on-camera demo that not only saw the 900 assaulted with the hammer, but used as a blunt instrument itself -- all without a crack or scratch. We imagine that other toughened-glass phones would survive the hit, and there's every possibility that smacking the polycarbonate plastic would leave more than a scuff mark. Nokia's test still proves that its pride and joy can withstand more than just a casual roughing up, and you can see the slightly cringe-inducing test in the video below.
