Corning says that its Gorilla Glass 4 offers twice the protection of Gorilla Glass 3

Corning says that its Gorilla Glass 4 offers twice the protection of Gorilla Glass 3
Corning has introduced Gorilla Glass 4, which is said to offer twice the protection against cracked and broken displays as the previous iteration of the product. Research done by the company suggests that dropping your phone (display side down) on a rough, hard surface is more likely to result in blood curdling screams and cries of desperation from smartphone owners.

Using 180-grit sandpaper to simulate these rough surfaces, Corning scientists dropped smartphone after smartphone from a height of 3.3 feet. Some of these handsets had screens protected with Gorilla Glass 4, while others used a competitor's coating. The result? Gorilla Glass 4 protected a phone's display from breaking 80% of the time.

Cliff Hund, president of Corning East Asia, said that sapphire glass is "top of the line" when it comes to "visible scratch resistance." But he adds that when damage or stress is introduced, sapphire trails Gorilla Glass in durability. Sapphire, which is the second hardest material on earth trailing only diamonds, is widely expected to be employed by Apple for the next iPhone. Poor yields from the finishing process forced Apple to skip using sapphire on the Apple iPhone 6 and Apple iPhone 6 Plus.

Meanwhile, Corning has started shipping out Gorilla Glass 4 to its smartphone producing partners, and we could see it in use as early as this quarter. For all of you butterfingers out there who cringe at the sound of smartphone display meeting concrete or any other surface, there is hope. Corning's Hund says about cracked screens, "I won’t say we’ve wiped it out, but we’ve taken a real large chunk out of it."



Thanks for the tip, Gilbert!

I have a feeling that even if the yields were good the company making the glass for Apple would have cracked. The entire operation was mismanaged from the start.

Soon we will start seeing phones made entirely of glass.

Maybe then we will have phones like the Nokia Gem (anyone remembers that video?)

I am of the camp even despite protection I use a screen protector and case as I can't stand having a marked phone

re the Apple iPhone 6

IMO I guess Vertu phones have caught Apples eye, Apple seeing Sapphire on arguably the most expensive phones an ANDROID phone wanted to emulate

Corning Gorilla glass is $3 THREE DOLLARS per phone
Sapphire Glass cost 10 times more $30 THIRTY DOLLARS per phone

The low yields reported were NOT as a result of GT but Apple in NOT wishing to add $30.00 production cost, instead use "Sapphire lite" [my words] as shown in these 2 articles
http://www.phonearena.com/news/Apple-receives-patent-for-sapphire-glass_id52043
http://www.gsmarena.com/apples_sapphire_display_cost_may_be_lower_than_we_think-news-9353.php

If the Sapphire "standard" coating which Vertu were used then both the iPhone6 & 6+ would have been Sapphire coated.

Apple has a strict profit margin markup policy which a FULL COST Sapphire coating would have lessened

My point is that you have 2 established ‘standards’ Gorilla glass & Sapphire coating.

What Apple offered in "Sapphire lite" no doubt would NOT be 100% standard Sapphire, and how it fared against the Gorilla glass 1, 2, or 3 iPhone 6 owners would NOT know.

All that would be "public" is iPhone use Sapphire and owners lulled into a totally false sense of security iPhone use Sapphire

Apple iPhones are premium (PRICE ONLY) devices
Apple have dropped Gorilla glass from the iPhone 6

Vertu was premium before they started using Android.

As for glass on the iPhone versus other phones, remember that Gorilla Glass was not even being reduced until Apple asked Corning to make it. Apple still uses GG, so nothing's changed.

As for GT, they were full of fail from the beginning, and their CEO is probably going to see jail time. Sucks for the employees, but the fault lies with their management.

How would using Symbian that Vertu has no control over the source code be more premium than using their own custom version of Android.

Please explain Napalm. Troll!!

What about their anti-reflective coating demonstrated a few months ago?

Corning Gorilla Glass is useless and always will!!! 1, 2, 3, 4 or even 10....

Lol pretty much. I don't know why phones don't just use a scratch resistant plastic like acrylic
