4.7-Inch iPhone 6 Front Panel Subjected to More Rigorous Scratch Tests, May Not Be Sapphire

That's not going to be a problem, because the iPhone is not going to fit in the pocket anyway.

You must wear some tiny pants, my pockets are about 6" across and the 4.7" won't even be 3" across, the 4" is just over 2" across.

So you are claiming apple DOES NOT use gorilla glass?

People in school can still have a livelihood. I worked through school from about 12 years old and up and it was my livelihood.
 
What I want to know, is how are all these people getting these supposed iPhone 6 front panels to test like this? At the end of the video even Joe Rogan has one and shoots an arrow through it. How many of these are floating around out there, and how are they getting them? And how do we even know if there's even a chance that they are real? Or is this just some Chinese part maker giving these out claiming they are iPhone parts, lol.

Oh boy, where was there bias in the video? All objective. Your looking for something that isn't there.

Or do you just feel threatened because apple isn't the only company that competes in the mobile market?

DING DING DING. We have the right answer!

You can always spot the one's who have the "Android hate" by the comments they post. They just have to find a way to insult the "enemy" or make them look bad.

I just realized it was the same poster you quoted. Makes it even more true. *sigh*

More likely it is aluminium oxide, which is a 9. Could also explain it.

Edit: Should have watched the video more closely. The ones he uses are (garnet) 7 and (emery) 8. So scratch wise it about the same as gorilla glass 3 (6.8). So maybe the 5s has gorilla 2 and this is the gorilla 3 panel.

One screen is installed in a phone and one screen is held loose in his hand and he's implying that the difference in sound is wholly due to the material.
:rolleyes:
Even identical screens are going to sound different under those circumstances.

OK linked the wrong calculator. I know it's the same angle out. It's been a while for me though. What does the angle of incidence need to be to get a 1cm lateral shift from synthetic sapphire, and what would the angle need to be for GG (or plain glass if GG specs aren't easily available)? That panel looked more like at least 1mm to me and more like 2mm thick, so go with 2mm? Are the angles different enough you could tell with a decent protractor?
Click to expand...

2mm is very thick for flexible glass, not to mention crystals (just to cover all the bases). The thickness of the entire 5s is under 9mm. A CD/DVD is 1.2mm, but let's say that it is 1.0mm, for the sake of argument. The lateral shift scales linearly with substrate thickness, so it is under 0.2mm of relative displacement between glass and sapphire, measured in a plane parallel to the substrate. This means that the spots also smear very significantly, and collimating a beam smaller than 2mm is very difficult. A 2mm beam would smear to more than double it's width, so we would be trying to detect a shift that is a small fraction of the beam width. There is a critical angle associated with light propagation in glass. If it is higher than a certain angle it cannot escape. You get close to this angle if you can illuminate the substrate at almost 90 degrees. For standard glass of an index of 1.5 this value is asin(1/1.5) = ~34deg. For sapphire this is asin(1/1.78) = ~42 deg. This means that the maximum relative shift of of spots between these two types of glass is 0.22mm per 1mm thickness of the glass. To get 1cm of differential shift, the glass would have to be more than 45mm thick. This is why the company that owns the web page you linked stays in business. This kind of thing isn't trivial to figure out without high precision tools, and this is one of the services they provide.

All the same one. There may of been one more used in the chinese video that was destroyed by a car.

The phone needs to not only fit but go deep into the pocket or else it'll fall out. My pants with the deepest pockets fit my iPhone 5 easily, but some of my pants barely fit it, causing it to fall out really easily. The other problem is that trendy pants (at least in the U.S., don't know about Mexico) have very small pockets for some reason. You have to carefully choose pants to get decent pockets here.

School costs money. I was dirt poor going through college because of tuition costs and my part time job was my livelihood. Marques has worked hard for his money so he deserves it.

Worked hard, he just makes some videos. And I thought in America you scabbed off your parents when you were in School, I thought it was when you were in College you had to earn money?

So what age are you in School till?Why do you have to pay for it?

Man, you don't know squat about Youtube revenue. Learn some facts before you post your false assumptions.

I love all these Apple lemming calling MKBHD an Android fanboy. Talk about a bunch of little black pots....

Please, if you're so enlightened tell us all how it works then. I mean you must be an expert to so vigorously claim I know nothing, apart from what you Tubers state on their videos that is.

Why don't you do it then instead of complaining about how people spend their money?

This is why you don't make generalizations. Marques is a successful youtuber, deal with it.

The different sound is the extra material of glass breaking off.
 
I'm just going to refrain from carrying sandpaper in my pocket, and stabbing my phone.

Yes, it's a sacrifice.

So you chose not to answer my question about American Schools then. Good for him being successful, if he wants to waste his money on thousands of dollars worth of camera then more for him. Total waste for You Tube.

Watching his video, it is flawed, for one he has a non stable piece of glass, and the other is it looks to me his iPhone 5S has a screen protector on it, but if not then who is going to do that to an iPhone 5S without someone sending them the phone, or paying them to do it?

Would you make a You Tube video and scratch the glass of all your devices?

It is that easy. Sigh. This is why China is kicking us across the room. Probably any Chinese HS student could do it too but in America we need special equipment?!? lol.

In fact you don't even need a number. Just compare it to a iP5 GG pane and see if it refracts more. Use a freaking flashlight and a pencil! This is basic stuff.

I just hope this is some kind of irony I don't understand. You can't possibly believe it works like that.

Well, I guess I'll have to stop carrying sandpaper around. Like I usually do.

Not a biggie. But how do you propose that one could stop carrying sand around? Aside from staying within a hermetically sealed lab at all times.

Pretty much any old piece of glass would qualify for that.

No. Silicon carbide sandpaper contains silicon carbide.

For all we know the scratches were done to that coating and the material underneath is made of sapphire. The truth is we won't know until it's formally released.

Well, we do know that it isn't sapphire, since sapphire doesn't bend like that.

The speculation was that in a composite layer with something else, it would...

To be honest I will be surprised and disappointed if the displays don't have sapphire in them, since Apple has so much sapphire production going on. I honestly don't get the scale or the level they're approaching it with if it's *just* for their wearable section.
 
Toltepeceno said:
Maybe just people are wanting it to be sapphire and they can't come out and say it's gg? I did read up on apples patent on flexible sapphire and the glass is not flexible, the liquid metal is.

Could be an entire new formulation of either one or a combination of both who knows. I do know its tough though and they will market the HELL! Out of it
