The other day we saw part one of a Nokia Lumia 920 stress test where the phone was dropped numerous times onto concrete and survived with only some minor cosmetic damage. The same site is back with even more 920 tortures: keys, a knife and a mallet.

The video shows the gent trying to scratch the 920’s display and body with the keys, both lightly (as if in your pocket) and then deliberately. Both times the Nokia survived with out any damage.

Next up was the knife test. Here the back of the phone, display and sides were all slashed with a very large knife and while the back and display did very well, the side of the 920 did take some significant damage. Still as the noted in the video, the Lumia 920 did very well with those slashes on the back nearly wiping off and the display looking unmarked from the horror movie slashing. Jason Voorhees would be a sad panda.

Finally, a mallet is taken to the phone’s display in two tests: dropped from 6 and 8 inches, numerous times and then later, deliberately smashed. Once again, the 920 was just fine with the Gorilla Glass 2 reinforced display not cracking under pressure. The phone was also used to hammer in a nail into a piece of wood without any damage either.

Conclusion? The Lumia 920 can take a lot of punishment though perhaps not surprising, if you slash it with a giant knife you can do some damage. Having said that, we have already heard anecdotal reports from users that their Lumia 920s have light scratches on them despite the lack of direct, purposeful trauma.

And we know for a fact that you if drop your phone directly on its corner, you stand a better chance of shattering that Gorilla Glass (see that image from a Reddit user). That’s because while the display on the 920 is hella strong, it’s not scratch proof nor is it unbreakable. It is simply scratch resistant, so try to treat it gently.
