Does the Samsung Focus Really Have Cornings Gorilla Glass?

I heard that the Samsung Focus had corning gorilla glass and hearing this I decided a screen protector wouldn't be needed (gorilla glass is supposed to be scratch resistant isn't it?). I'm the type of person who takes extra steps to protect his gadgets. I always hold my phone with a firm grip, I have a dedicated pocket for it (no keys or coins with it) and I never drop it. Recently I've noticed some scratches appearing on the front screen of my Focus. Most of them aren't very noticeable, but one in particular can be seen plain as day and is infuriating. Like I said, I don't have anything in my pockets, I've never dropped it and I want to know how these scratches appear on "scratch resistant" glass if nothing but my fingers and cloth are touching it.
If the Focus doesn't have the gorilla glass/gorilla glass isn't scratch resistant I will delete this thread in shame of my lack of knowledge

the zune HD has gorilla glass and I have a zune and a focus. I am reasonably sure the focus isnt gorilla glass, taps like plastic and scratches relatively easy. my zune has very little scratches after 8 months of abuse sharing pockets w/ keys; only one day with my focus in my pocket with my wallet i have scratches.

It does really seem like plastic. Or maybe really thin, versatile glass.

I asked Samsung via twitter on November 9th and they confirmed it
"the Focus does have Gorilla Glass. Thanks for reaching out to us, we're happy to help. ^Sab"

Just found this and it says the Samsung Focus does have gorilla glass.
http://www.samsung.com/us/article/get-to-know-the-samsung-focus-with-windows-phone-7
Is it possible I got a bad unit? Or is it possible Samsung is just using the weakest gorilla glass?
EDIT: Dang, same time post

Samsung claims that the Focus has Gorilla Glass, so I guess you can just take their word for it. The Gorilla Glass might be underneath the plastic layer Samsung used. I think the Vibrant and European Galaxy S are the same way.
Here's a link to Samsung's official site Q&A about the Focus and if you scroll down you'll find that they confirmed it has Gorilla Glass. Click here. Also an official SamsungUSA rep on Twitter confirmed Gorilla Glass when he was asked. Click here.
Also, if you want to see a stress test of the Galaxy S' Gorilla Glass, check out this video (not in English but you get the gist of it). Click here.
I bought a silicone case for it and for now I don't have a screen protector but things are going fine for me. The phone probably isn't bulletproof and considering how thin the Gorilla Glass is on the Focus it will do an exceptional job stopping the usual accidents but it won't stop anything more serious. But since you're an 'extra protection' kind of guy you should just get the screen protector and give yourself some peace of mind lol.

Usually I get a case, but I haven't found anything to appealing yet (I like for my phone to look good). Also I try to keep it in the best condition so when I go to resell it I get maximum value

The screen feels identical withmy Captivate...

yes it is gorilla glass... ive put a few in already and can confirm.. plus i called samsung to be double sure...

huh, okey, guess i am wrong.
But my zune seems like its a lot harder. ive babied my focus and I still get scratches easyer

Exactly. I want to know why that is.

glass scratches.. bottom line..
gorilla glass is just harder to scratch and is a tougher glass overall so it can be made thinner than other glass digitizers...

They probably have another layer over the Gorilla glass.
The Focus's screen really feels like plastic. It's just not as solid as, say, the iPhone 4 (which is said to use Gorilla glass for the front.) Gorilla glass is supposed to be scratch-proof and you scratched it in a day? Hmm...

I do not have a case or a screen protector on my Focus and don't have a single scratch on the screen and only a few micro scuffs on the plastic battery cover. I am generally careful with my gadgets, but I have carried this phone with me every day since Nov 8th and both of my young children play with it on a regular basis, and still nothing. Thankfully I have not dropped it screen side down on any hard surfaces (knock on wood)!

It is not scratch proof.. It is much more scratch resistant... No glass is scratchproof
www.corninggorillaglass.com. Its a good read.

I can tell you from personal experience that a Focus screen will not survive a 3 foot fall on its face to concrete. And it is very very much made of glass.
But it seems relatively scratch resistant : )

Have you guys seen the youtube video of a guy testing out the glass screen of the focus? He's literally stabbing the phone with a screwdriver and smacking it with the handle and there was no scratches on the phone afterwards.

It's supposed to be extremely hard to scratch, even with a razor blade. The iPhone is practically invincible when it comes to keys and the like.
http://www.youtube.com/watch?v=TkXlriABfOo . It's a good watch.
http://www.youtube.com/watch?v=_8yNh0N2qbs . This video too is essential for discussions like this. Basically, to scratch the iPhone's glass, you need something that's harder than the glass they used. So diamonds might scratch it. Metal, not so much.
If this guy's Samsung Focus's screen went to hell after one pocket session, methinks the Gorilla glass they used was made in Chinese ghettos.

I'm not lying, I have no reason to be. I've also had the phone for about a week (and a half) and I think I might have actually dropped it once on the rubber foot mat of a car, but that was only like a 2 foot drop and it was rubber. I'm still perplexed as to how this scratch got on my Focus. I have some other little "soft" scratches, but those you can't see unless the screen is turned off and its at the right angle. The one I'm referring to is small, but when I use my Focus outside you can notice it (even on the black theme). I tried taking a picture, but it wouldn't come out.
Would it be possible to exchange it for another Focus at AT&T if I'm still in my 30 day trail period?

You'd have to talk to them, but I doubt it. Usually physical wear and tear isn't really covered. But couldn't you return it and then buy another one?
I'm assuming you got the scratch when the phone landed screen-down on the floor mat of the car. There are usually tiny rocks and some are bound to be more solid than the glass, thus the tiny scratch. So 'unlucky' then, I suppose.

guess what happens when you drop your S2 face down on a gravel road

I dropped my GS2 on a gravel road from about chest high, glass side down. I picked it up and the screen was completely dusty and horrible looking and I said UhOh. I got a microfiber cloth and wiped off the phone after blowing as much as possible of the screen. Got it all wiped off, and in direct sunlight at every angle, not a single scratch, blemish, pit, nothing lol. I have a slim gel on the phone, but the screen is naked. Whew!

Cool!
Peep peep.

It's called Gorilla Glass for a reason - gorillas are well known for their high resistance to being dropped by humans onto gravel.

I liked that someone experimented with Gorilla Glass

Swore I was going to read chest pains followed by back to back heart attacks until death.
Glad to hear it's ok.

WINNING ^^

Yeah I decided to forego the cases and the screen protectors after seeing some videos (not produced by screen protector sellers).
I was using Reallook but it got to slimy and even carrying the phone in my pocket with keys, only the plastic edges gets a little nicked. My Captivate's screen never had a scratch and I am the most un anal person when it comes to worrying about scratches on the body of the handset. Under everyday conditions the glass really is scratch resistant and I would say scratch proof in a pocket with keys.

Gorilla glass is good stuff......The "screen protector" makers are so scared of it they are posting questionable videos on YouTube of how "easy" it is to scratch. "fear" is a great advertising tactic and sells a lot of things. In fact the glass is amazingly resistant to scratching.
I would be more worried about the interior circuitry shock on a drop than the glass.

As long as HTC is in business, the screen protector people will be too. You can look at an HTC screen wrong and scratch it.

You are very lucky. Its a different story if you drop it in the sea or fall in with it in your pocket
Put it this way I've got a very expensive piece of gorilla glass for a coaster. Ohh and a spare battery that I'm too scared to use :-(
I must admit I got a zagg invisishield screen protector and it is awful. Wonder why they bothered ohh try money.

I dropped a galaxy S1 from about waist high onto concrete. it bounced about 5 times before come to rest face down.
The LCD screen under the glass was cracked into 20 different pieces. But the glass itself - not even a single scratch. You had to hold at it an angle to see the broken lcd pieces. So while the gorilla glass is strong, the screen inside itself is pretty flaky, so dont be droppin it!

Yeah Thats what I am talking about....The glass is like Pyrex...maybe even stronger. The interior parts are the issue with drops. That's where those thick soft silicone cases help out but I don't care for cases as the ones that could really protect the phone make it too bulky and the thin cases are a waste and only prevent scratches and nicks around the edges. I don;t worry about those. Never used the same phone for more than a couple years if that long. The back cover can be folded in half and if ever needed replaced easily.

That's nonsense, they scratch just as easily as the sgs2, I will let you decide how easily that is since most htc devices also use gorilla glass

"Both Gorilla Glass 3 AND Dragontrail X are used for Z3C's display"

I've received an answer from official Sony support staff over at the Sony Mobile support forums, on a thread regarding which type of glass is used for the Z3C. It turns out that for the display, both Gorilla Glass 3 AND Dragontrail X are used. Unfortunately, no info on the rear glass:
"For the display glass we use both Gorilla 3 and Dragontrail X but i'm afraid i don't have any detailed information about the rear glass."
http://talk.sonymobile.com/t5/Xperi...ss-is-on-Xperia-Z3-Compact/m-p/838927#U838927

Is that a "and" or an "or"?
So those who have Gorilla glass breaks easily but harder to scratch.
Those who have Dragontrail scratches easily and harder to break?
Which? I heard users saying it is easy to scratch and easy to break! Perhaps, they are talking about the Z1 or Z2.

If this is true I think I may have gotten the Dragontrail version because I have been pretty careful with the phone os far and already have a small scratch on the upper right. I think I would choose scratch protection over drop protection in the end because scratches are drive me ****ing nuts.

So if yours is a Dragontrail, use PET film. If Gorilla glass, use tempered glass. Problem solved!
Just need to know about the backside. To date, no one makes a tempered glass for the backside.

Why PET for Dragontrail?

For those with true balls, give us a scratch test, attempt to scratch your device and post it on you tube LOL

Just received mine. If you squeeze the phone in the middle with your thumb and index finger, there is some flex. Almost feels hallow.

That's completely normal.

Agreed. I am going to have a Case anyway if I
get a Z3 C and would prefer Corning GG 3 or GG2 as a known performer versus Dragontrail
which has a cool name but what is it ?
Godzilla Glass and Dragontrail sound good but give me GG3. Corning Gorilla Glass.
And give me a gel case with outer shell and I will add glass screen protectors front and back.
The Manager at Sony Store Miami which does not have Z3 or Z3 C yet mentioned " Tempered Glass " for the back as what Sony calls it.
Thanks for posting your experiences .

They use Both but you won't know Which is on your phone, like the z1c had Both jdi display and another lowcost brand so by chance you could get a superbright display or a not-so-good one.

Or they use none of both and Sony support just has no clue whatsoever

After 5 days I have absolutely no microscratches. I still put it in my pocket with other things (not keys though). In addition GG 3 also gets scratched by harder materials like sand, glass, concrete. If you have sand in your pocket or mineral dust it will be scratched if it's not made of sapphire glass (which would be scratched by diamond)...

I've had my phone for 7 days now and I checked under the bright lights at work and I have a bunch of micro scratches on the back, very disappointing. My phone is carried in my pocket by itself, or set on my desk so I have no idea where such scratches could come from. It's only on the back though, the front looks fine, so maybe they're using some inferior glass for the rear.

I think gorilla glass 2/3 or dragon tail doesn't really make that much difference....
I read somewhere the key is the strength retention after the glass has been scratched. I think Gorilla 3 perform better to retain that strength. All of the glass has very similar spec.

Don't know if this deserved a separate thread but will post here as well.
Today I woke up and realized that my screen is broken. One think line. My guess that is happened yesterday cause phone touch was acting up in the evening but it's hard to see without much light.
My phone is in case, has a stock screen protector and was never dropped or impacted.
My guess that this is low quality from zony's side. Reminds me the crack that reviewers had on their back plate in one of the first review videos.

It's a smudge magnet. But my finger glides very smoothly on it and it's easy to clean. Usually it "cleans itself" in my pocket so when I take it out after having a walked around for a while, the screen is usually relatively clean.

Gorilla glass is a bit of a joke isn't it?

Apparently this stuff is indestructible, however I've never dropped my phone, never put it in a pocket with any coins or keys etc, it's always by itself, yet I have two sizeable scratches on my screen.
Anybody else having this issue?

I've scratched every gorilla glass phone I've own. Most of the time it happens when I just have my phone in my pocket.

People underestimate the capabilities of dand particle. That is actually the real horror. This is why i have used a screen protector on everz device ive owned after my htc one x. Onthe n4, g2 and g3.. Not willing to risk scratches im rrally picky about that

I totally disagree with your point. Whether its gorilla glass or not, the glass has to come to contact with something to get scratch on the surface of glass and in your case gorilla glass without you aware of it.

Yup, I always end up scratching it with normal usage, but I don't mind anymore, I don't like constantly trying to pamper my phone haha

Never scratched a phone screen, never buy screen protectors.

I took a fork to the Droid X screen and tried to scratch the screen with all I had. There were very slight thin lines but the screen looked great for the most part after such abuse. This was the original strength gorilla glass. None of my other GG phones have had scratches. I've had a good experience with them.

I have never used screen protectors and my previous device was s2 which I had it for 3 years without even a single scratch
Needless to say I'm so careful and I don't even let my screen get dirty by touches and leave it for a while. Because I don't like the feeling of touching a dirty surface.

Gorilla glass is basically polycarbonate plastic. Polycarb scratches easily, as anyone with modern glasses will attest to.
But in my experience, the scratches are very faint.

I've got a deep scratch. Only had phone in pocket. Not great.

Rubbish

I always use a screen protector. Considering their cost and what you risk if you don't use one (irreversible damage) I don't see any valid reason to not use one.

Mine has severe erosion from a simple smooth cloth protector that that a little fold in it. And that after the first week with light usage (just work and home where it just sat on my desk).
Never seen such a bad glass, the old S2 has survived much much worse and still has a flawless screen.

Why first thing I always get is a tempered glass screen protector, and I try to have one put on before I even leave the store.
I can attest to the tempered glass screen protector. . Had it on my Note 3, my little kid threw my phone against the wall, glass screen scattered but the phone screen was perfect. Replace the glass screen protector and you're good to go

Question about the glass on 6P

Anyone know about whether the 6P use Gorilla 4th gen glass or not? Since I read some review said it does, but nothing mentioned on official site.
If it use Gorilla, I probably just leave the phone naked, it's so sexy with any case or film.

every smartphone since 2010 has used some form of gorilla glass. your statement is confusing to me. glass is inherently soft, therefore scratches are inevitable. i'm not sure GG4 will have much impact on daily usage.

Really? I thought the GG4 is some sort of anti-scratch. I used screen protector on all my phones before, however I took it off from my G2 last year and so far so good. Without any film it feels better imo

AS I understand it, gorilla glass is very strong when faced with direct face hits, thus resistant to scratching. As such it becomes weak to forces from the sides which makes it more likely to shatter. The newer versions are more resistant to shattering but that still is their weak point.

The nexus team confirmed GG4 when they did the AMA on reddit

Use a tempered glass screen protector. Looks good, feels good, protects the actual glass. Film screen protectors are dead to me.

Glass display on smart phones are not soft. Glass is a ceramic. The problem is that dirt, sand, diamond, etc is harder and that can scratch glass.
Gorilla glass just does a treatment to harden the surface making it more resistant to scratches and leaving the internal glass "softer" so it can resist drops and impact that shatter.
