If you’ve ever owned a high-end smartphone, then you must have noticed that the glass covering your phone’s display doesn’t get scratched easily or never gets scratched at all. This is due to the fact that smartphone manufacturers use a specially treated glass, most commonly the Corning’s Gorilla Glass that’s immune to such damages.

While Corning currently leads the industry with its world-famous Gorilla Glass screens, it’s only inevitable for its competitor to come out with a better alternative. Recently, the makers of Sapphire glass have been claiming to dethrone the Corning’s Gorilla Glass soon but now it seems like they’ve got a lot of work to do before they can even say that.


Corning has shot down claims that sapphire could someday replace its Gorilla Glass screens, as it recently ran tests of its toughest Gorilla Glass 3 material and compared it with its own lab-grown sapphire sheets. In the end, it concluded that sapphire is just a little more scratch-resistant but still just as prone to damage and breaking.

In a statement to CNET, Corning’s senior vice president and operations chief of staff Jeff Evenson said that samples of their in-house and lab-grown sapphire could not best Corning’s Gorilla Glass 3 in the classic tumble test, where devices are spun for 45 minutes to see how it fares against scratches. With that said, Corning says that it doesn’t plan on using sapphire alternatives instead of Gorilla Glass any time soon.

However, keep in mind that while Corning’s Gorilla Glass is mightily strong as compared to its competitors, smartphone with such protection still tends to break when dropped from a great height. So make sure you keep you device in a protective case to protect your device. Do you keep your smartphone inside a protective case?
