A hockey puck is made of about six ounces of hardened rubber. It's hard to put a dent in one, and it has to be, because after a few games anything weaker would look like the "after" images at the NHTSA testing facility. A smartphone is made of plastic, metal, glass, and various bits of circuit board and other electronics, none of which is designed to be smacked repeatedly by sticks and ice. Unless you have a "ruggedized" model like Samsung's various Active phones, of course.
As part of YouTube's "Awesome Stuff Week," the Unbox Therapy channel decided to see if a Galaxy S6 Active could stand up to the punishing job of being a hockey puck stand-in. You wouldn't drop most phones on the ice for an hour of full-contact skating, but the bulky, impact-absorbing body of the S6 Active might make you consider it if you have no alternative. Check it out:
The phone manages to survive a little practice, and even a few punishing slapshots and slams against the wall and the post. But after a little time in a full-contact game, the phone finally gives up the ghost and the screen shatters. (Hey Unbox Therapy, if you ever want to run this test again, I nominate the DROID Turbo 2 and whatever the latest model of the Caterpillar CAT phone is this year.)
Full disclosure: the video is officially sponsored by YouTube, which I suppose makes this an ad of sorts, for them if not for Samsung. We didn't get paid to post it here, but we did have fun watching some phones get wrecked.
