Dial Back The Hype: Alleged iPhone 6 Display Fails Sandpaper Test, Suggesting Screen Isn't Pure Sapphire

Apple still hasn't announced its next iPhone, but that hasn't stopped the Internet from talking about and leaking information in relation to what's likely to be called the iPhone 6. Much of the recent focus has been on the iPhone 6's supposed sapphire crystal display, a seemingly much more resilient material than Corning's Gorilla Glass and the same material Apple uses on the Touch ID home button and camera cover for the iPhone 5S. Or is it? A new video has us second guessing the iPhone 6 display's true make up.

In a previous video, Marques Brownlee, host of the YouTube channel MKBHD, showed the alleged iPhone 6's sapphire crystal display standing up to a number of different torture tests. Brownlee tried scratching the display with a set of keys, followed by jabbing the panel with a knife, both of which failed to leave a scratch. He also bent the display backward to an uncomfortable angle, but it never snapped or cracked.

iPhone 6 Scratched

A few days later, a Chinese-language video emerged with even more forms of abuse on what it claims is an iPhone 6 display. Once again, the panel proved durable, withstanding fire, hammers and nails, a box cutter, and more. The only test it failed was being run over by a vehicle.

This all bodes well for iPhone fans, though there's evidence suggesting the iPhone 6's display probably isn't pure sapphire, and it's certainly not scratch proof. Brownlee just posted a follow up video, this time using different sandpaper grits. In doing so, he was able to scratch the iPhone 6's display rather easily.


So, what's going on? Brownlee concludes that the iPhone 6's display is not pure sapphire like the Touch ID home button. Instead, Brownlee believes Apple is using a "composite involving sapphire." His suspicion is reinforced by the fact that Apple already patented a fusion process in which a sapphire structure can be mechanically modified to reduce chipping or fracturing.

This isn't necessarily a bad thing. According to Brownloee, using a large slab of pure sapphire crystal for the main display would be costly, while also making the phone too rigid. A little bit of play is desirable to keep the display from shattering, and that's what the composite material allows for.

That's too bad. I was really excited for that screen. Well, sort of. If the next iPhones don't have user-serviceable batteries, I don't think I'll go with Apple.

Could have been the new Guerrilla Glass which was rumored to have a similar qualities.

lol... Ok... i'm no fan of Apple... but really guys? Because it was scratched by SANDPAPER, now you don't want it? lol

How many of you actually plan on taking sandpaper to your phone?

Apple selling something that isn't what it appears to be? Imagine that.

Shoot! I won't be able to walk around with sand paper in my pocket anymore :( Screen still looks like it will be pretty durable. I'm excited to see the other upgrades Apple makes to this new phone!

Sapphire is aluminum oxide, the stuff often used to make sandpaper. Just as diamond can scratch diamond, sapphire can scratch sapphire.

Well, no one is going to carry sandpaper in their pockets, but it could simulate dropping your phone onto pavement and it sliding. I like the end bit where they shot it with an arrow! HAHA

Well if the screen is actually pure sapphire, it would cost significantly more than it should have been with the current screen (part sapphire)
