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.
Hi guys!
For this test I used a set of keys and a cutter.

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.

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'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.
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.

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 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.

Looks like Gorilla Glass on Axon 7 is not tough enough, I broker my screen this weekend. Was in museum and phone fell from my hand onto a wooden floor of museum, and screen is shattered. Although it is functional and working, the screen glass is broken. I think I'm bit less impressed with the screen toughness of this thing. A phone fell from hand roughly 5 feet above ground, onto a floor and it shatters the glass. Am I covered by Axon 2 year warranty on this one or I need to get it fixed on my own ?

Agreed. It's "GLASS", not iron. And hard glass is difficult to scratch but is brittle. Do people not understand hardness? Lol
The harder a substance is the more difficult it is to scratch but also the harder something is the more brittle it is.
Tungsten is a very hard metal... But people don't realize if you drop a pure tungsten ring it most likely will shatter. Same concept.
If you want glass that isn't super brittle it will scratch easier. If you want glass that won't scratch it will be brittle. Until we find some kind of super glass this is how it will be.
That's pretty much result as expected.....
You can RMA but they probably charge you a deductible as it would consider an accident.

Much of it depends on the angle of impact. I know several people who have cracked their Galaxy Edges on fairly benign drops. Almost everybody I know with an iPhone (not that many) have at least one crack in the screen, but since it doesn't impair usage they often just keep on using the phone.

Exactly. A drop is not a drop and the angle is much more important than the height.

Never heard about that nor learned about it in college, but that's also probably one of the reasons I stopped going because they don't really teach you anything nowadays. Anyway I digress, the harder a substance is the more brittle it will become.
I mean look at Diamonds, the hardest substance known to man and yet it can be shattered quite easily
interesting comparison

People don't understand Gorilla Glass. It's not about how strong it is, but how scratch resistant. And believe me, Gorilla Glass 4 is REALLY scratch resistant. Everyone could possible break when dropped on a wooden floor.
Do you come under the 6 month screen repair?

Which is why I'm glad the Axon 7 uses it instead of the easily scratched Gorilla Glass 5. I don't care in the least about shatter resistant, I don't drop my phones, ever. However I do want to be able to use my phone without an oil magnet (aka screen protector) so it's super important to me that it be scratch resistant as possible. That's why I'm hoping there will eventually be sapphire screens (though it seems unlikely). I was pleasantly surprised to hear that the A7's camera lens is covered by sapphire.
Seeing as how the Axon 7 design is very similar to the htc one m8, this gripe is justified, if you ask me. The lack of edge to edge glass creates a buffer between the corners of the phone and the edge of the glass. I dropped my htc one m8 flat on concrete, more than once, and not a scratch. I was hoping the Axon 7 would have the same type of durability.
gorilla glass is not shatterproof just like Moto Droid turbo 2/X force/Z force . these phones have such a great shatterproof glass. have a look https://www.youtube.com/watch?v=-V2r_9Um2Tw
All of these iphone screens are cracked:

That is not shatter proof "glass" it's plastic. I know because I just sold one.
