Toughened glass has long protected your phone against a singular drop, but one-and-done isn't how it works in real life -- we've all seen butterfingers users whose device falls to the floor on a seemingly weekly basis. Those not-so-coordinated people might have a little less to worry about going forward. Corning has unveiled Gorilla Glass 6, whose composition has been altered to better survive multiple drops without breaking. In tests, it could handle an average of 15 drops on to a rough surface from 3.3 feet. That's up to twice as good as Gorilla Glass 5, and supposedly much better than rivals whose glass might not even make it through the first fall.
