EDIT: I stand corrected. It doesnt appear to be the "gorilla glass". Its more like a tempered glass. Sorry for the misleading title.
Video above:
Reviewer did multiple scratch tests on the phone:
1) sharp metal objects inside a ziplock bag
2) use of a sharp nail
3) sharp screw
Hardly any scratch on the screen itself. Only when a box cutter was introduced did it enable a scratch to appear.
Also did a drop test: 3 hip level drop and 1 head level drop. Only after the 4th drop did the screen crack. However, the phone still seemed to work.
I don't understand Korean, but the box cutters look like they scratched the screen.
Strange test that show galaxy not scratch proof.
You tube vdo does not show fine scratches all over the phone that normally bothers everyday users.

Isn't gorilla glass just a marketing term for a plastic-glass composite made by corning. It's "gorilla" since it's more scratch resistant than polycarbonate just like any other glass-plastic composite/laminate would be. I'm sure the glass on the Galaxy S is virtually identical to that of the latest Iphone.
Gorilla Glass is a brand name I think?

Corning is a brand, Gorilla Glass is a product name.
Gorilla Glass is a name for toughened alluminosillicate glass. It is specifically distributed by Corning and telling people that you got a Lamborghini when you really got a ferrari is lying, even though they are both good. Tempered glass != gorilla, and it isn't certain that the newest iPhone has gorilla. They just say so b/c it's scratch resistant.
well, i had the galaxy s in my trouser pocket for one day.
there where no other things (keys etc.) in the pocket, only the phone.
in the evening i noticed a scratch on the display (not large, but visible on a bright background).
thankfully i was able to replace the phone with a new one, now i carry it in a bag all the time and i put a screen protector on the display.
Rough pockets eh? Screens just don't scratch themselves. You did something.

yeah, for sure
all i know is, when i have a new device i handle them with uttermost care.
as there was no bag with the galaxy i had to carry it one day without using one.
but i guess you are right and i should have known, that the cotton that pocket trousers are made of is known for its screen cutting and scratching properties.
of course, it could have been my fingernails. who knows?
Please hold back your remarks about screen protectors this was a replacement, only the second day I had it, didnt have a chance to purchase one.

Think you could post a pic of the damage? if it's not too deep, i've heard of people using this product called applesauce that is supposed to give really good results. Maybe try that out and see how it works. Good luck to you, hope you get the scuffs out
You could try rubbing compound which is used on watches and things.

Yeah, just thought of this after I read this post but you can also try the stuff that is used to fill in cracks for car windshields.
light scuffs
I've heard that white toothpaste can be used on light scuffs on plastic.
or perhaps Brasso polish?
The screen on the evo is made of gorilla glass, not plastic. Therefore acid based compounds such as applesauce or lcd scuff removers on the market would not work. The famous banana slice/peel trick doesn't work here either. Some compounds for watches only clean the surface of the glass and remove dirt from within the scratches, making the scratch less visible.
Your best bet is to clean the glass to remove all dirt then install a screen protector like invisibleshield to mask the scratches. This will work better since a liquid solution (usually 1 part soap and 9 parts water) is applied to the screen so you can squeegee out all the air during installation. The only downside to this is the texture feels like apple skin and screen clarity is affected...maybe 15-20%.

Not sure if it's made of Gorilla glass-- not saying that it scratches easily (because it probably doesn't), but I found I had a two very,very slight surface scratches on the screen after babying it for a month (always put it in an empty pocket with no keys/coins/etc, never set it face down, etc).
In any case, I wouldn't try using toothpaste, brasso, or any other solution on the screen except for an eyeglass/electronic screen cleaner as you'll probably end up creating more noticable scratches. Just clean the screen as well as you can, and throw on a screen protector, and you'll probably never notice the scratch-- most very small scratches are only noticable when viewing the screen at a very oblique angle to catch a reflected light source, and the screen protector blocks this.
Also, I wouldn't recommend the ZAGG. I had never used a ZAGG screen protector before, but have heard great things about them, and I'm not particularly picky or sensitive about screen protectors. However, I found the Zagg protector had a horrible rubbery feel to it, and gave the screen a really bad and noticable orange peel effect (actually, the effect seemed more like the screen was behind a 1/4" layer of ice). I put on a cheapo $1.99 screen protector from Gizmo Dorks (on Amazon.com), and the difference was like night and day-- the screen was just as smooth and clear as the original glass.
I have a few too... Leave it be and after a couple weeks you'll forget you even have them.
Can we buy the glass yet for this phone? I replace iPhone 3G and 3GS glass on an almost daily basis at work.

He might... but I'm not sure a $100 deductible + limited further coverage is worth a few small scuffs. I guess it depends on how bad they are, but if they are anything like mine it totally would not be worth it.

Since the debate is going back n forth about the glass.....what is the difference between the two? Sure i could search but since there's a debate I think it should be explained this thread...
I looked all over and can't find anything confirming it's Gorilla Glass so I assume it's not. Plus I wouldn't find so many people with easily cracked screens if it was...

I posted one a bit ago but that was with some knives....the box cutter is impressive.
I am more worried about the small pieces of sand, I think that is what scratches the glass more......But, this video has me almost convinced that I do not need a screen protector.

Wow, this just proves that all the other people complaining about scratches just don't take care of their phones.

well a material can only be exceptionally flexible(ductile) or hard(strong), but never both. if you want a material to be more shatter resistant(ductile), then it'll be softer and less scratch resistant. Conversely a harder material will be more scratch resistant but more brittle and prone to shatter. its always a tradeoff between these two physical qualities.

Your problem occurred from a defect in the glass manufacturing process. I don't think that is a standard.

Although this is true in some cases it is not in all. Thanks to chemist and material scientist, treating or chemically finishing materials could give the best of both worlds. Go watch the gorilla glass test on YouTube, it is more scratch resistant than its competitors and almost twice as flexible.
Gorilla Glass has a lot to do with its surface finish as well as the glass itself.

Gorrilla or not, Its still glass!!!
Bottom line is anything harder than Gorilla glass which has a hardness between 8+9 will scratch the surface.
Iron, steel, nickel, lead, gold, silver or any medal are softer than gorilla glass, so they should not scratch the glass.
On the other hand, sand contains quartz and it could scratch gorilla glass, for example when sand is in your pockets (after a walk on the beach).
One more thing:
a common misconception is: 'make something sharp and it will scratch'. it's wrong. you can make your fingernail or your key as sharp as possible, it is still softer than the glass and it will not scratch.
So, no, keys wont scratch it (steel), but anything harder than 8 on the scale will with no problem. So anybody that has no scratches obviously hasnt made contact to the screen with anything harder than a 8 on this scale.

Not very relevant at all. ALthough what you say is true, it is not the hardness of Gorilla Glass that lets it perform the way it does, it's the way it is chemically treated that allows it to resist scratches.
You are just talking about a mechanical property but not taking in mind the material process. Yes those materials will eventually scratch the glass (common sense), but whatever the coating on the glass is has to wear off first.
Chemical treatments. There's definitely a lot more to it, I would have to read more extensive datasheets, but here are some.
http://www.corninggorillaglass.com/sites/all/files/GG2%20PI%20Sheet%20Rev%20b_050912.pdf
Corning® Gorilla® Glass 2 is an environmentally friendly alkalialuminosilicate thin sheet glass that is better able to survive the real world events that most commonly cause glass failure. Its superior
composition allows a deeper layer of chemical strengthening than is
possible with most other chemically strengthened glasses — making it
both durable and damage resistant.

I think the Dragontail glass is actually much stronger than gorilla glass, so it makes sense to protect the screen with the better material (which probably also costs alot more than gorilla glass).

Depends what you mean by stronger. The vickers hardness rating of Dragontail is lower than Gorilla Glass. But typically harder quite often means more brittle, able to shatter. So the trade off are hardness and flexibility to adsorb impact and be scratch resitant.
Asahi dragontail glass is aparently aiming to be stronger than Gorilla glass. At this stage it appears that they are trying to gain market share from Corning, so would be highly unlikely that this glass will be much different in price.
I saw a demonstration of Gorilla glass 3, hard to beat that. http://www.engadget.com/2013/01/08/gorilla-glass-3-hands-on/ But I am sure dragontail are right on their tail if not already. No one seems to be claiming that their glass is the strongest, in fact seem to play it off to being similar in strength.
I am sure that Sony has some contract with Corning, which is why they are using this on their TV's etc, so I guess that they had to use at least some corning glass until any contracts expire.
With Sony being Japanese and Dragontail being Japanese I am sure it has a lot to do with Japanese loyalty and cheaper, and am certain that they will likely convert entirely over to dragontail in all their products in the future once any contracts expire.
