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.

Although this video makes me think that either this guy had a diamond in his pocket or he's extremely unlucky. Or lying...

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.

Gorilla glass and Gorilla glass

A major plus with the SGSII is the Gorilla Glass on the display, but the million dollar question is what it has on the camera lens?
I love not having to worry about the screen on my Nokia N8 (also Gorilla glass), but am always wary about the camera lens which is "scratch resistent mineral glass" although it's generally recessed in its housing enough not to be a real issue.
Looking at the SGSII videos and pictures, however, it looks as though it will rest solidly - and directly - on the lens cover of the camera in the back (and of couse that's not part of an easily replacable component like the battery hatch).
So - are we going to be able to put our phones down face up without worry?

You shouldn't worry, scratches on lenses isn't really a problem. The reason is a because of how optics in lenses/cameras work. The surface on the lense is so far from focus that a scratch on the lens isn't projected on the lens as a scratch. Of course, a big damage will cause visible effects though.
I'd really like to add some links with info, but I'm not allowed, really a pity that new users cannot prove their information.
But try to google:
kurtmunger dirty lens
and
tech arp lens elements for scratches
for some info

Isn't the SGS and ALL iPhones supposed to have 'Gorrilla Glass'? iPhone's shatter like no-one's business; is it a lie? Like the cake?

Depends how you abuse a phone. iPhones shatter because they are small and slick and have hard metal around the edge that directly transfers impact force to everything else because it is the frame of the phone (plastic or metal that is attached to frame would dampen the impact somewhat) Also I think it is the back of the iPhone that shatters, and that glass is not as good as the screen glass.
tjtj4444: great first post. I agree 100%, small scratches are not visible to the image sensor when focused on something far away. A finger smudge is worse. So I hope those lenses are oleophobic

The camera cover on the Samsung Galaxy S2 is suppose to be depressed behind the phone. I don't think it will be vulnerable to scratches and severe damage. However, as in the case of all tech-gadgets, over the years of ownership, there should be visible signs of wear and tear. If these signs of wear of don't appear over time, then I have to say, you must be a very careful owner, lol.

I'm none too worried about an odd scratch, but more of multiple scratches. I remember being crushed when my Samsung i900 arrived with two scratches on the lens, but they never affected the photos.
On my Desire, however, I got so many scratches that they caught enough light to have the same effect as grease on the lens. Fortunately with the Desire, I replaced the battery cover multiple times and eventually just popped the lens cover out of one.
So, no, an occasional scratch won't ruin it forever, but multiple, repeated scratches will.

Gorilla glass isn't even that good honestly. It seems to be great for demonstrations where people actively try to damage it with keys and stuff but when you use it in the real world, stuff like sand and fine debris can easily mess the screen up.

On the forums here, someone stated that their LG Optimus 2X screen shattered and he is looking for a replacement, he eventually found the necessary parts, but my thought is that if it can shatter with just a drop, whats to say that this is a one time occurrence? Although there is no doubt its stronger than mineral glass and Apple's Glass.

Im not so sure about that; I had my Captivate for about 7 months and nnever used a screen protecter.
I dropped the phone multiple times from various heights along with bumps, bangs,and stuffing in pockets.
Not a single scratch; the phone looked like hell too, However if you cover the body you'd think it was new.

i used samsung omnia hd for 1 and a half year without any screen protector. and when i sold it, not even a single scratch wwas there. gorilla glass really works

Is there any official confirmation of Gorilla Glass?

Yeah, it definitely works. The flooring in my bathroom almost has a sandpaper consistency (yeah, lovely, I know, but it's a rental flat), and my record of inflicting damage on my phones is nothing I'm proud of, but I mostly blame that da%& flooring.
And, yet, I must have slid my Nokia N8 face down across that thing like 4-5 times and there's not a mark on the glass (the anodized aluminum is another matter unfortunately).
I'd be gutted if it turned out the SGSII didn't have Gorilla Glass. Last thing I need now is another phone with a grease-magnet screen protector.

I am sure Gorilla Glass is great but does it TRULY protect it against scratches from daily use?
Thats what they said about the iPhone but you do end up getting it scratched.
Perhaps Invisible shield for the back and sides and go bare in the front would be the optimal way.

You have to distinguish between scratching the actual screen versus scratching the oleophobic coating off. The iPhone has had the coating since the 3GS so it's a lot easier to scratch it off than to actually scratch the screen.
I've had a Vibrant (Gorilla Glass with no coating) and a few Nexus S's (no gorilla glass but oleophobic coating) and I abused the crap out of the Vibrant but it stayed flawless. The Nexus S... had the coating come off but if you clean it well you won't notice until you grease up the screen again, then the lack of coating becomes apparent. Even still, it stood up pretty well and it feels amazing compared to a screen without the coating.

So a screen protector is not needed or to have it is just a benefit?

If it has Gorilla Glass, I will definitely be going without a screen protector.
Sure an added layer of protection wouldn't hurt, but it comes at the cost of a plastic protector that attracts more dust and grime, detracting from the touch, feel and appearance of the device.

i'm sure it will have gorilla glass.... that seemed to be the trend with this past gen of samsung's Galaxy labeled phones

Of course we know it's got Gorilla Glass on the screen, but anyone know about the lens?

Just an FYI, I've read lots of posts by SGS owners who got scratches on the screen just by carrying the phone in their pocket. I don't doubt any of the reports by posters here, but Google "I scratched my Gorilla glass" and you might not be so confident.

Where are all the "trying to scratch the SGS2 screen with a butcher knife" videos ???

Where are all the "trying to scratch the SGS2 screen with a butcher knife" videos ???
Samsung went to great lenghts to make the screen both scratch resistant, and finger friendly (meaning oil resistant, using a very special coating). They are advocating a non screen-protector use. So, where are all the videos of people showing us it is indeed scratch resistant ?
(to think of it, I haven't seen any durability tests done for the SGS2, which kinds of make you wonder...).

you make one, I am not going to, I already found out the hard way gorilla glass does scratch (luckily not on my sgs2 though)

They are not saying the screen can't be scratched, rather not easily. The knife test was always used as a proof that a screen is indeed harder to scratch. But I haven't seen any test like that for the SGS2...
My fear is that the very special coating they put on the screen (the coating that makes it oil-resistant and such a joy to slide your fingers on) IS scratchable, and will not survive a knife test.

That coating must be rubbish, as i think i've rubbed mine off wiping the fingerprints off. everytime i pull it out my pocket now there always a big smudge on it.

Yeah the fingerprint resistant coating scratches VERY easily. There was a thread somewhere here that had a guy posting about trying to remove a scratch with a polishing agent. He did get rid of the scratch but ended up removing the outer coating aswell.

Second that, i used it the first day without any screen protector and it was smudged all over with fingerprints. My hands were clean, i'm not a car mechanic Next day i bought a screen protector, at least that will protect it from scratches, since i can see my fingerprints with or without a screen protector.

I leave these advance test to more experienced and much more brilliant individuals.

I literally cringed when he went to town with the screw and then the paper cutter.

If Samsung offered free replacement for scratched screens, I would burn my screen protector right now!

Are you kidding me ?
1. He DID scratch it eventually !, look at 3:02 minutes.
2. This is not the S2 device, rather the S1. The S2 has a special oil-resistant coating, which the S1 does not have. There is question whether this new coating is more sensitive to scratch than the Gorilla Glass itself.

Scratch resistant doesn't mean it's scratch proof. Everything can be overcome when countered with the correct amount. Gorilla glass does help preventing scratches but it is not the ultimate armour against scratches.

SGS II Camera Protection?

I had my first hairline scratch for SGS2 within 4 days of usage. Probably the Oleophobic coating it had which is more prone than Gorilla Glass.
I hurried to get a Screen protector but what about the camera?
Nobody in the forum seemed to be concerned about giving the 8MP's a decent protection.
Anyone here use a old SP on the lens or leave it as it is?
For a scratch-phobia user like me, probably not leaving chances to luck.

Once I fixed a piece of a screen protector (which corresponded to area of the home button) on the camera's glass but it made my pictures terrible, specially because I covered the flash also. then I removed it. However it was one of the cheapest screen protector. A crystal clear one might be a different story.

Isn't compass showing towards your camera all the time?

I bought the SGP Ultra Capsule case for SGS2. It makes the phone about 1-2 mm thicker so when you put the phone on a flat surface the camera stays intact. Same goes for the screen. I've never used or even liked phone cases before but this case is awesome, my friends didn't even notice my phone had a case It also comes with a Crystal Clear screen protector so you can cut it to make a piece for your camera.
Oh and about the screen. The SGS2 screen is made of Gorilla Glass and has oleophobic coating. Oleophobic coating is not a glass type but coating, something that is added on top of the glass. And that coating doesn't scratch so you can't say that SGS2 is more prone to scratches due to the coating.

Yeap you're right. It should be the scratch-resistant (not proof) gorilla glass. I must make it clear that the scratch is a negligible hairline that only shows when screen's off.

Worst money spent on a SP.

enough with cheap screen protector.
Try brando ultraclear and you won't regret it (brando don't pay me).
jokes aside, i had a pleomax screen protector with anti fingerprint treatment that work but the colors were bad. With the brando now i have the fingerprint but the colors are perfect and it's like there is not protector on the screen.

thanks man!
right now there're a few major downsides to SP for SGS2
Anti Fingerprint SP
+No Smudges
- Rainbow speckled display can drive some people mad when the purpose of SGS2 is it's beautiful AMOLED display. I mean, whats the point? Lol.
Crystal Clear SP
+Almost Naked SP
- Smudges.
Note: I am not too sure the extent of smudges on SP affecting user experiences.
But in short, with respect to thread's subject, I find many people have really unique ways to Sealing their SGS2 from wear and tear and by far the Magnet cover is the most creative and unique.
Solutions to SP for Camera
1) Get Martin Field's SP. They come with Camera SP. But they're only ones to do so.
2) Get a cheap crystal SP
3) Use a expensive SP just for the Camera SP.
Afterthoughts
I can't seem to abandon the thought of leaving the camera's glass Naked. I feel so uneasy when I lay it on the table, not knowing when some loose staplers or sand strikes/scratches.
Meanwhile I leave it to my case' thickness to safeguard my camera's glass for the time being...

"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.
http://www.evolutivelabs.com/blogs/news/11840361-gorilla-glass-2-vs-3

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.
