Corning today unveiled its new Gorilla Glass 4, its next-generation glass production that is even more resistant than previous versions to glass shattering drops. According to Corning, the company extensively studied shattered screens to understand how and why they break. The culmination of this testing was Gorilla Glass 4, which reportedly is two times stronger than competing products and can survive 80% of face-down falls onto rough surfaces such as sandpaper.
