A few days ago, there was a bit of controversy on the web regarding the use (or lack thereof) of sapphire crystal in the camera lens cover. YouTube channel JerryRigEverything took the trouble to test the durability of the new iPhone 7. In this durability test, he also focused on what it can withstand Home Button and the camera cover. Both of these parts are supposed to be made of sapphire, but tests have shown that they scratch much more easily than sapphire glass would normally. The author of the original video released another one over the weekend, which significantly expands on the previous one. For example, an electron microscope comes into play, and now we can take a look at what the cover is actually made of.

You can watch the video below, which is very interesting by the way. In it, the author once again demonstrates the durability of the camera cover, compared to the sapphire crystal on the back.carTissot watches. The watch is very durable, only a tool with a hardness of 9 can visibly damage it. The iPhone camera cover is definitely not that durable. Although Apple they claim on the website that it is made of sapphire, the same material as the watch glass.
Only the results from the electron microscope will give us the answer, which will examine in great detail what the entire cover is actually made of. And the results show that although it is a sapphire, it is nowhere near as high quality as the one in the watch. It contains various residual additives that reduce its quality. In the same way, it is not a pure sapphire, but a special surface treatment plays a certain role here, which significantly affects the resistance of the material itself. The video is really interesting and we recommend watching it. Apple so officially he is not lying, but it would be wrong to associate their concept of sapphire with the resistance of this material, which it usually possesses.

Considering that it is "clear" glass over the lenses, it is probably a priority that it does not reduce the brightness. How is it with the clarity for the sapphire optics? Hardness is much more important to me than "clarity" in a watch.
But maybe I'm wrong - some photographer could explain.
Sapphire should be less suitable than classic glass. From what I understood, it shouldn't transmit light so flawlessly, unlike normal glass. But sapphire is more durable...
Apple he's not lying, but could you call it deceiving the customer?
It's a shame, the camera deserves better protection.
In the video he claims that iPhone The 5S has sapphire, but no more iPhone 5 had it, right? I've had it for 4 years and it doesn't have a single scratch, unlike the glass around it. Even the lens removed from the phone won't change it, it withstood a needle with a hardness of 7, the camera can be scratched with quartz, sand, iron, asphalt, any coin and keys... I think anything harder is really unnecessary.
The glass contains sapphire but is more prone to scratches because Apple he reportedly used one more layer for luminosity. Well, if that's the case, he didn't even have to use sapphire glass, because the first layer gets scratched and the layer underneath, which should be able to withstand something, won't save it anymore :)
Mam iphone 6 for two years, my wife has ip5s for 3 years and no scratch on the camera or HB. I work in an engineering company (pretty aggressive environment) so far everything is ok. So this whole discussion about sapphire glass is irrelevant.
it also seems to me that it is unnecessarily exaggerated here whether it is scratched or not. the surface of the glass on the lens is so small compared to the display that it is useless to decide if and in what way it will be scratched. I was always more worried about not scratching the glass on the display than the camera.
Even though the protruding lens of iPhone The 6S and 7 are really ugly, so from a practical point of view it's not the stupidest solution.
Especially when you put the 7 Plus on a table, it almost doesn't move.ancand scratch.
Paradoxically, users who use their iPhone If you put it in a protective case, the cover glass will merge with the plane when placed on the table and the protection is gone.
I notice that a lot of people put their iPhones with the screen down, with a tempered glass cover, why not, but it's such masochism.
