The new Samsung Galaxy S4 comes with a new feature that hasn't been covered heavily in the media. It includes the next generation of Gorilla Glass, version 3. Apparently, Gorilla Glass 2 simply made the original Gorilla Glass thinner and lighter rather than increasing its scratch resistance. The 3rd-gen version actually increases the strength of the glass as well, which can result in a 40% reduction of visibile scratches compared to the original Gorilla Glass.
An enterprising blogger decided to put this new glass technology resistance to the test, by pitting the new Gorilla Glass 3 equipped SGS4 up against pennies, keys, and knives! Check out the video above for the results.
