Corning, cover glass supplier for Apple, Samsung and other device makers, announced today its ultrastrong Gorilla Glass 6 will make its debut on Oppo's next flagship phone. 

Unveiled in July, Gorilla Glass 6 is tested to survive drops from heights of 1 meter (3.28 feet) onto rough surfaces. In its tests, the glass lasted through 15 drops, double the amount of Gorilla Glass 5.
