    When do we think the Sapphire glass used on the camera lens will be affordable enough to be used on the screen? Or if it ever will be? (Surely it will?)

    We've had it used on mobile phone camera lenses for a number of years (since the original iPhone?), so you'd think prices would've dropped since then.

    Surprised there hasn't been word on it being considered for use on the screen of a phone (Apple, Samsung etc.) any time soon.

    In many cases the scratching may be in the oleophobic coating not the screen itself. The iPhone X screen has a level 6/7 hardness.

    The sapphire used over the camera lens is not pure sapphire and is basically as scratch resistant as the glass currently used on the front and back, not nearly as scratch resistant as pure sapphire.

    HTC has a sapphire version of the U Ultra which is pure sapphire. Hopefully Apple is able to implement this sooner rather then later.

    I think there has to be a more substantiated cost associated with a larger display for Sapphire, as it's not inexpensive to manufacture based off previous readings.

    Hmm thanks. Watching that makes me feel better about using a case that protects the camera....not as invincible as I thought!

    I always thought it was a few 'tiers' higher on the robust scale, as evidenced by that EverythingApplePro bloke who tests the glass with various materials - the camera lens usually lasts one or two rounds more than the screen. Maybe not an accurate test?

    Found the vid here...grade 6 material scratches the back & grade 8 material scratches the camera lens. But yeah, your above vid says a lot more about the Sapphire Glass used in iPhone camera lenses.

    Never, pure sapphire has too many disadvantages when used as a display glass.

    Even if they used it you‘d still see scratches due to the oleophobic coating covering it. It‘s either that or have to wipe off fingerprints after every touch gesture.

    Well for what’s its worth I had a Kyocera device with a sapphire screen. It was amazing. Zero scratching. And I tried. Excellent

    As far as I am aware sapphire pays for its scratch resistance with brittleness and reflectivity; it’s much more susceptible to shattering on impact, and also has worse optical qualities than the current glass.

    Never, Apple tried to do that by investing in GT Advanced Technologies and it blew up in their faces (mostly due to their own missteps)

    I don't believe the coating will be necessary with pure sapphire. All of my sapphire watch faces are super slick. The brittle nature of sapphire makes in impractical for such a large size/application as a phone screen.

    Sapphire is more scratch resistant than glass, but it is also more brittle and will shatter more easily.

    Do you think that we may see a sapphire screen on the iPhone Xs successor in 2018?

    Would you be happy to pay extra for a more expensive/premium iPhone with this? Perhaps an iPhone EDITION.

    i don't think sapphire is the right thing for a phone screen. sure it won't scratch but it'll crack super super easy

    Highly doubtful. It's also likely substantially more expensive to manufacture sapphire on a larger display such as the iPhone.

    But if it were to be offered, I would be interested in it. I can see how the added protection is certainly worth the investment with the Apple Watch stainless model
    Sapphire dislay. I still don't have any scratches on my stainless Apple Watch dislay.

    It would be outstanding for scratch protection, awful for durability. The only issue I see is sapphire has a tendency to reflect light badly, this is why watch companies usually use a AR coating to reduce the effect. The AR coating can be scratched even though the sapphire can’t..
