Corning's Gorilla Glass 4 Promises Stronger Protection for Falls Onto Rough Surfaces

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.

Corning scientists examined hundreds of broken devices and found that damage caused by sharp contact accounted for more than 70 percent of field failures. The scientists then developed new drop-test methods that simulate real-world break events, based on thousands of hours analyzing cover glass that had broken in the field or laboratory.
The culmination of this testing was Gorilla Glass 4, which reportedly is two times stronger than competing products and can survive 80 percent of face-down falls onto rough surfaces such as sandpaper. The company also claims the glass retains most of its initial strength following a shatter-free fall.


Corning is long-time supplier for Apple, providing the Cupertino company with Gorilla Glass for its iPhone and iPad lineup. Apple considered using the scratch-resistant sapphire for its iPhone display, but its partnership with GT Advanced fell apart when the supplier declared bankruptcy earlier this year.

Corning says product shipments of Gorilla Glass 4 to customers are already underway, making it a strong candidate for inclusion on next year's iOS devices should sapphire remain an infeasible option.

FINALLY. Now my iPhone will survive all of those drops onto inconveniently placed sandpaper while I'm running around town.

Ahh, what a cute gorilla.

I want to take it home as a pet.

Oh, wait. What is this article about?

I admire people like them, continue challenging to a higher standard.
This is an obvious contrast to the other supplier who sold out his own company.

I was looking up images of sandpaper, when I found these inspirational words by Chris Colfer. I'm not sure how this relates to the story, but I thought it would be helpful to those with Samsung devices.

Show me the CORNER DROP test results. Figure out how to stop the spiderweb cracks.


That's the problem. There is no such known material. Even screens made of diamond would shatter just as easily. The shatter-proof, scratch-proof transparent rectangle requires a whole new, breakthrough innovation much like the all-month battery. It's beyond anything that exists now at any price.

I suspect it will be easier to invent anti-gravity so that a future iDevice can sense that it's falling, activate the anti-grav and float in for a feather-soft landing. As "out there" as that sounds, the challenge involved is probably about the same.

I wonder if that has anything to do with Corning's new product, or if it is simply a marketing term they've come up with to avoid admitting that they use Gorilla Glass (as they historically have)?


I went to Corning gorilla glass website and Apple isn't listed as a device using gorilla glass, hmm...


Yep. For whatever reason, Apple has never allowed Corning to acknowledge their relationship.


Apple doesn't admit to it because Apple doesn't want to tie their brand name to another brand name. All other components in Apple products are just components and several of them come from multiple manufacturers. Otherwise the Retina Display would become the Sharp Aquos HD+ Display, or the A8X would become the Samsung Galaxy Trifecta Xtreme Processor. Apple doesn't want to be tied to Gorilla Glass or people would start calling it the Gorilla Glass display. If Apple moves away from GG then people might think that the new display is inferior since Corning has a dominant market position.

I love how they only show woman dropping their phones. Also "sandpaper" to replace concrete as a "real world" substitute? That is laughable. Why not just test the drops on concrete? Thats sounds more "real world" to me.
