Samsung Galaxy S4’s Gorilla Glass 3 stress test proves its mettle

Here is a video from a Samsung Mobiler Szabolcs Ignacz  who did stress testing on the Galaxy S4’s display. The test started by using a ball point pen (striking the display and writing on the display), then a set of knives are used to run slicing patterns and hit the GS4 and finally set of keys and coins are used to try the same. In the end, the GS4’s Gorilla Glass 3 comes out without a scratch.
