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?
I am quite concerned about this phone's durability especially if it drops flat on the face. Galaxy s had its body slightly coming out so that protected the glass from impact, but note has its glass fully exposed to a drop and then bam. So did anybody drop it yet? I'd love to shell out for a case but there aren't any useful ones so far, hopefully one will come out in near future.
The gorilla glass should help with this.

Most of the times the glass is ok but the underlying lcd can give away
I thought the Gorilla Glass was just for scratch proofing!? My Streak shattered when I dropped that and I think that uses Gorilla glass. I'm very keen for the nice slim gel covers to appear on ebay or wherever, very worried about dropping it..
It's up to you to decide whether you want a screen protector or not, but there were too many people with misconceptions over at the discussion thread. Please discuss Protector vs No protector over there.
Here are a couple of misconceptions about Gorilla Glass and it's scratch resistance (source links below).
------------------------------------------------------------
Misconception 1: Gorilla Glass does not scratch???!?!?!?!?!?
Absolutely FALSE. While it's true that Gorilla Glass is scratch resistant to many materials, some will scratch Gorilla Glass. Gorilla Glass is reported to have a hardness of 7 (some say it is as high as 9. I've reached out to Corning for their "official" value, since they only use Vickers to measure hardness) in the Mohs scale, so any material with higher hardness, such as sand, diamond, or other minerals , will scratch your screen.
So, if you drop your phone, and if it happens to land on a grain of sand, it will scratch your Gorilla Glass screen. Or, if a grain a sand goes into your pocket where you keep your phone, then the screen may be scratched.
To those who didn't learn hardness scale in elementary school: materials with lower hardness than 7, such as steel knife, coins, or car keys, will never be able to scratch Gorilla Glass no matter how POINTY and SHARP it is. You can shatter the glass using a steel knife with enough force, but you cannot scratch it.
----------------------------------------------------------------
Misconception 2: The oleophobic coating, not the glass itself, is what's causing the scratches, so use sand paper to grind the coating away!!!!!!!!!
DON'T!. According to Corning's own documents (link below), the anti-brasion/oleophobic coating on the Gorilla Glass actually provides better scratch resistance than "naked" glass surface.
Corning performed an experiment where half of the Gorilla glass was treated with the coating and the other half was naked Gorilla Glass, and they rubbed silicon carbide sand paper on it. You can see the resulting picture on the link below. To use their words, there was a "significant scratching on the non-coated region whereas few visible scratches existed on the coating".
If you already have scratches on your Gorilla Glass screen, then it would've been worse had the coating not been there.
-------------------------------------------------------------
I hope that clears up.

It's not just for phones. It's for everything that has Gorilla Glass.
Looking forward to diamond screens!
Gorilla glass has a good resistance when you try to break it or the phone falls down, but it isn't indestructible.
Thread cleaned. Lets not Troll, derail or flame

Anyone who did use sand paper on his/her SCREEN should consider not buying a phone at all....

Thanks for information, perfect to know what to expect from some stuff, if it will scratch or not.
Please revise your article, see:

Gorilla glass was originally developed to be shatter resistant. It's debatable if it offers more scratch resistance than regular glass, and it may actually be slightly less scratch resistant than regular glass. In most case (not all) higher shatter resistance = less scratch resistance (IE, plastic). I've been telling people for awhile that if you have a glass screen, a good screen protector is a good way to get peace of mind.
To those who didn't learn hardness scale in elementary school, materials with lower hardness than 7, such as steel knife, coins, or car keys, will never be able to scratch Gorilla Glass no matter how POINTY and SHARP it is.

So basically if i grab a steel knife and scratch my phone with all possible strenght on earth, my phone will not scratch ?
Gorilla glass was intended to be put together with stuff like your keys, coins etc

Force can lead to shattering, but you won't scratch it. Ask yourself this, how many scratches are on your car's windshield? How about the windows of your house? Take your car keys or even a steak knife and run the edge along your house or car windows. Any scratches?
Yes, if you take it and stab glass with all of your strength, you have the potential of shattering it. You can do the same by throwing a rock. But that's not the same as scratching.

Exactly. There is a difference between fracturing and scratching.
That is why phones like s3 with gorilla glass still shatter when dropped.

I posted this in the screen protector discussion thread, mentioned by the OP:
"One more thing and i'm done with this! I found out how it is now, according to:

[2] http://en.m.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness
[3] http://en.m.wikipedia.org/wiki/Sand
Mohs scale:
[1]
Gorilla Glass - 9
[2]
Random metals - 0.2 to 8
Tungsten - 9 to? 9.5
Titanium - 9.5 to? 10
Diamond - 10
Quartz (SiO2) - 7
[3]
SAND (composition: mainly SiO2 + other rocks and minerals, location dependent) - 7 to 10!
CHEERS!
So in CONCLUSION: if you happen to rub sand, containing diamond (extreme case) on your phone, it will scratch.
I also found this: "Misconceptions about Gorilla Glass" on XDA http://forum.xda-developers.com/showthread.php?t=1866049 He sais that gorilla glass is 7, but i found out it is 9 [1].
He talked about another aspect that he sais is on cornings own website, that what actually scratch on a gorilla glass is the oleophibic coating. Oleophobic coating? Maaan my phone always looks like a friteuse! Maybe screen protectors do better... Also maybe thats why some sources say its a 7.
My conclusion: i wouldnt use a screen protector to cover my good looking screen. Im always pretty careful with it, not dropping it on floor or concrete. I very rarely to never have dirt in my pockets. Keys, lighters and such, wont hurt it. So who cares about protectors? I dont."

True, ignorance is bliss. Please post comments on screen protectors in the do we really need a screen protector thread mentionrd by the op.
And @ OP. Please throughly rethink your article...
Or at least mention that sand mainly contains quartz which is 7 (gorilla glass is 9 and cant logically be 7, because else we would use normal glass which is mainly quarz + additives and it's a bit under 7), and sand in general has 7 to 10 depending on composition.

I bought a galaxy s advance 8 months ago and it says it has a gorrila glass screen, but i swear it scratches more easily than my old Galaxy s,
i just wondered what people thought of the screen on the nexus 4?
cheers
jon
The original Galaxy S also features gorilla glas.
As far as I know gorilla glas 2 is just i thinner version of gorilla glas so it's going to be just as hard/easy to scratch as the screen on the Galaxy S.
I think the S2 uses Gorilla Glass 1 and I've not had any scratches on that over the past year. I'm guessing if this is the next version it should be stronger and more scratch resistant.

Nope. Same resistance, just in a thinner form. Which makes your phone thinner, lighter and the screen brighter and more responsive to touch.
