    Hello guys! I searched the internet and I found that there are some minor residues of sapphire into the camera lenses of the latest iPhones and into the home buttons of the iPhones prior iPhone X.

    The iPhones are probably the most popular smartphone brand in the world. Why wouldn't Apple release an iPhone with a Sapphire Display that doesn't require a screen protector to cover it from fine scratching?

    A sapphire screen would also be more brittle and shatter more easy.

    Does there need to be one? Wouldn't it be wise to just keep strengthening glass?

    This is why the iPhone 6 didn’t get a sapphire screen

    Not just that, but they are so reflective it basically ruins your experience in high ambient lighting.

    This is true, as an example, that was a problem with the first generation stainless steel Apple Watch, was that the sapphire display was creating a glare in direct sunlight or a brighter room, and Apple remedied that by increasing the brightness from 450 Nits to 1000 Nits with the Series 2, which made a massive difference in actually reading the display with a sapphire display in all lighting conditions. Given the iPhone has a fairly bright display, if they were to use a Sapphire display, that’s something that they would have to consider increasing the brightness for a better readability.

    Production capacity is insufficient to meet demand.

    Sapphire cracks just like glass.

    It's much cheaper to replace glass on an iPhone than sapphire.

    The HTC U Ultra Limited Edition had a sapphire display. It cost roughly £115 more than the glass version. But as far as I know it was only available in Taiwan. It was limited for a reason. It’s not so much the extra cost but issues manufacturing sapphire displays in volume. Certainly the volumes that Apple would require.

    It would be very brittle compared to the hardened plastic.

    To be honest, I’d be willing to pay the premium if sapphire was an option that could be added onto the iPhone hypothetically. If anyone has any experience with the stainless steel Apple Watch with the Sapphire display, then they know how durable the sapphire really is again scratches and scuffs, it’s literally almost impervious to damage, assuming Apple uses a decent quality sapphire display. No one wants to look at scratches on their iPhone display, sapphire may not be the answer for everyone, but it certainly serves it’s purpose.

    Well all it needs is a good anti reflecting coating. My Omega watch has an amazing coating; a friend says it looks like there's nothing there at all.

    It seems there are a lot of reasons why they don't use them, shatter resistance probably being a big one... But it would be nice to have a basically scratch proof display!

    Appreciate the responses.

    So the next question is why hasn’t current Gorilla glass advanced enough to prevent fine scratches, even on screens of those who take care of their phone?

    Because innovation in materials science does not happen on a schedule. An old Star Trek quote... "You can't simply say, 'Today I will be brilliant!"

    Everything happens for a reason - in this case, the reason is physics.

    Apple has developed their own Ion-X Glass for the lower-end WATCH. It isn’t likely to replace gorilla glass anytime soon, though. Same with Sapphire, which has advantages but also disadvantages over gorilla glass.

    Gorilla glass is currently on its third generation, so it has become much better - but it’s still glass, ie the same component. As such, it too has advantages over sapphire.

    Both glasses have their advantages and disadvantages. The Ion x glass from Apple has the advantage that it is simply much more flexible than the sapphire. Tests show that the ion x glass can withstand 2.5 times more weight in a bend than the sapphire. If you drop an Apple Watch with Ion x glass, the display does not crack quite as fast as an Apple Watch with sapphire.

    The Ion X glass also has the advantage of being much lighter and cheaper. That’s why Apple uses it in the cheap Apple Watch sports variant.

    The big drawback with the Ion X glass is, unfortunately, that it is easier to scratch. It is scratch resistance to keys or coins though. The sapphire has the advantage that it is very difficult to scratch.

    Sapphire has a 9 in degree of hardness, which is directly below the diamond with the degree of 10. It is therefore about 25% stronger than the ion x glass, as far as this point is concerned.

    Unfortunately the sapphire is much more expensive and is not as flexible as the Ion x glass. In other words, it will shatter easier and will break quicker when bent. If you weigh it, you will notice that it is 67% heavier.

    So, it’s a question of which compromise will you make?

    Apple wanted to address the cost by their deal with GT Advanced Technologies, but didn’t count on them being crooks and defrauding them.

    No iPhone has a sapphire-covered camera lens. Watch JerryRigEverything’s videos on his durability tests. The covers are regular glass and scratch much easier than sapphire.

    So... it’s basically false advertising by Apple. Oh well.

    Patently false statement. The same argument was brought up before, and Phil Schiller debunked that even using the iPhone 7, noting that the camera lens cover and home button is both sapphire. He directly quotes that in article below:

    JerryRigEverything HATES Apple, I can't watch the guy as all he does is bash Apple.
