Video: Used on over four and a half billion devices around the world so far, Corning's Gorilla Glass is the gold standard for smartphone and tablet screens because of its scratch and shatter resistance. The current generation of Gorilla Glass can resist a drop from a metre in height up to 80 per cent of the time, giving you a pretty good chance of keeping your smartphone alive if it slips out of your jeans pocket. The next generation of Gorilla Glass is even better, with clearer optical properties, better scratch-proofing and the ability to resist a drop from 1.6 metres.
