[Q] Gorilla Glass?

Anyone know how scratch resistant the Epic's screen will be?
If its weak, I'd like to manually try and replace it with Gorilla Glass.

Manually replacing the glass sounds kind of risky!

You should realize that gorilla glass and products like it are much more brittle than standard glasses. While it can with stand scratches, it doesn't favor well in drops and impacts to it. Why not just use an invisible shield or other protector? Much cheaper and easier.

Trying to replace a screen that's made for the phone with a screen that's NOT made for the phone isnt gonna be easy or pretty.
when it comes to a drop/impact that would shatter or splinter the screen, it either will or won't. Having a case and protector on the screen helps. But if its from more than 2 feet, most likely the screen will shatter regardless of the type of glass.

My Hero has survived far more of its fair share of 5 foot falls onto asphalt with only minimal scuffing to the plastic case, there are no screen cracks, and no screen scratches either. If the Epic 4G is anything similar, it should be fine with both. Although I would like to note that, at least for me I would worry more about problems with the keyboard after the phone has been dropped, as was the case with my Touch Pro. Just my 1.9 cents.

One of the benefits of super amoled is that the screen is attached to the plastic/glass cover. It eliminated the dust and glare problems but it would most likely be impossible to replace it.

One of the great things about the HTC "chin" phones is that it's impossible to directly impact the screen on a flat surface like a floor or sidewalk without completely breaking the phone open. That's how it is on my G1, at least. Say what you will about the aesthetics, but I find that to be fantastic practical design.

When I went to the T-Mobile store to see their version, they intentionally dropped it and banged the screen HARD like 5 times to demonstrate how tough it was. Not a scratch. I wouldn't worry about screen durability.

Not gonna happen...they sell the display phone they drop to the customer ..lol jk....
Overall though I had plenty of LCD phones and I dropped them..threw them from room to room and never had any damage...I remember at one point I dropped my phone every day for like 6 months..but then again maybe I'm one of the lucky ppl :/

Take a look at the Galaxy S brutal tests and judge for yourself.

Flinch indeed!!, I thought " The Cove" was bad.

What's with all the gorilla glass stuff lately? As previously said gorilla glass isn't suitable for the Epic 4G because of the Super Amoled display, on top of this Gorilla glass is very scratch proof but at the sametime it's not meant to be dropped.

Glass
Yep its tuff glass

WTH would you bump a 7 month old thread?

My Epic fell out of my pocket screen first onto a rock when I was getting out of my car a few days ago and didn't have a scratch/crack or anything on it.
The silicon case, however, got chipped.

As long as he did, I wanna say I'm pissed at how easily my Epic screen scratched. Weak.

Does froyo make the glass faster?

I demonstrated Gorilla Glass to a coworker of mine last week, when I whipped out my keys, attempted to scratch and jab the hell out of my screen while he winced and told me to stop because it was painful to watch.
Side note: I live just an hour or so from Corning, and I've been to the glass museum there. Wouldn't think a museum about glass could be particularly interesting but it's actually worth seeing.

I have some scratches on my phone already lol

I have scratches too. I have always used screen protectors, love this phone without them, and am still very careful.
However, one day in my purse, got about 3
Do you think this means they would cover the screen under warranty? Definitely did not abuse, so . . .

most likely not a warranty issue. After all, it's not the phone's fault the scratches appeared
/sarcasm
I had someone come into the service dept. once with their nice new honda on the back of a tow truck wanting honda to pay for a new engine. They drove their car into a really deep puddle and ingested some water and siezed it up. They were screaming 'warranty' blah blah... the service manager said as politely as he could "it's not honda's fault your car went into a puddle".. I ran into the bathroom and laughed my ass off.

Simple science, my friend. Steel, on the hardness scale, ranges between 4 and 5. Our Gorilla Glass is nearly a 7 (typical glass is closer to 6). Unless you go at it with hardened steel (like a high-quality kitchen knife) the glass won't be scratched.
People often wonder why their screens develop small scratches anyhow, and it's usually because of sand in their pockets. Sand tends to contain quartz, which is slightly harder than glass (even Gorilla Glass), and as such, can scratch it.
So while I'll take out my car key and scratch the hell out of my Epic, you wouldn't catch me putting sand on my screen in a million years.
Wikipedia has a pretty good chart of hardnesses. http://en.wikipedia.org/wiki/Hardness_scale
Also, Corning has some documents with plenty of graphs comparing it to standard glass here: http://www.corninggorillaglass.com/literature

They could just use normal gorilla glass with a 1 micron thick coating of diamond. But yea, would still be expensive as hell, not because of the cost of the diamond but due to the manufacturing process taking forever.

The problem with diamond is that it's very brittle. The hardness scale is typically inversely proportional to how brittle it is. I agree that diamond coated something would be virtually scratch proof, but I would think if you knocked it just right, it would shatter.
Going back to keys on the screen. I always laugh when I hear people doing this. I usually ask people how sharp they would have to make their fingernail to scratch glass. It's the same idea. People assume that because something is sharp, it will scratch anything.
Having said that, I would be careful about trying to scratch the screen with keys, not because the keys would scratch it, but there could be something sticking on the keys that could (not likely, but not unheard of).
I have a visible scratch that's about 1 cm long, and it annoys me. I think it was on the night stand, and I slid it off to hit the snooze for my alarm. Later that day, I noticed it, so I must have had some kind of grit on the night stand. Ugh.

I thought diamonds were the hardest substance because of the way the molecules interlace? Wouldn't the density of the molecules make it less brittle too? I can understand if there was a lot of space from one to another, but not when its all packed together...

A diamond is a crystal, and the atoms are in a very rigid structure that has very strong bonds. Because the bonds are strong, it's difficult to separate them, so it is also very hard (i.e. something that has weaker bonds would not be able to break the strong bonds, so the atoms in steel would break apart when rubbed against a diamond and not be able to scratch the diamond). The problem is that these strong bonds make it so it is very inflexible, which in turn makes it very brittle. In this case, the density of a diamond doesn't have anything to do with it.

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...

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=_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.

Before I rip off my screen protector....

So i really want to see if the screen protector is causing my touch issues as shown here:
http://www.youtube.com/watch?v=M1fijZt9-B0
But don't want to rip it off if its not going to fix the problem. Can anyone confirm whether or not this is the case?

Bit the bullet, ripped off the screen protector, all my touch screen issues have been alleviated!!

Screen protectors are a myth. I have a nexus 7 2013 and S4. Been without a screen protector for months on both, not a single scratch. Hell, the S3 I gave my wife (and she ain't as careful with hey phones as I am), not a single scratch. The fortified or gorilla glass on modern devices work quite well under normal conditions. Don't be doing extreme sports or outdoor activities with your N7 and you will be good.

Actually, I would like to believe that. However, the scratched up screen on my old G2X (Gorilla Glass) begs to differ with you. Within ONE WEEK of getting my Nexus 4, it had a small scratch on the screen. I put a screen protector and haven't looked back. My N7 now has a screen protector as well.
Thing is, they're scratch RESISTANT not scratch PROOF. If you're getting no scratches, then great. You don't have a source of sand made of harder minerals than Gorilla Glass. A lot of us aren't so lucky. Dirt around here apparently does have "hard sand" in it, so the slightest bit of dirt in my pockets, and the screen gets scratchy. Thus, screen protector.
Many people don't like screen protectors because of lousy installation. Properly applied screen protectors should be invisible. Getting one properly applied can be troublesome. I watched a friend of mine buy the expensive ones at T-Mobile and had the rep do it. He had no clue what he was doing, and tried to pass one off on them with DEBRIS under it claiming that would go away on its own. They made him redo it again, and the second time, the edges were damaged and ugly where he put his fingers all over it. I have properly applied ones on my phone & N7, and you can't even tell they're there unless you look closely at the edges.
Making a blanket statement based on nothing more than your own personal experiences that screen protectors aren't necessary is hardly scientific or valid. Maybe for you, they're not necessary. Some of us are a bit more OCD about not having scratches on our screens and choose to avoid that with screen protectors.

All do respect, but what are you exactly doing with your devices? I know full well that these devices are not meant to be rugged by any stretch of the imagination. I treat them very gently. I'm just as OCD about scratches as you are. That's why I take the upmost care of these costly devices and treat them very carefully.

Once your screen meets any small amount of sand and your screen has micro scratches you may change your tune. It's OK to go without a protector if you don't mind these hardly noticeable scratches, or the feel of the glass when the oleophobic coating finally starts to wear off. However, for those of us who want to avoid this problems, a good screen protector goes a long way. I know that when I resell the device that it will be in mint condition. Besides, a decent, properly installed protector will be unnoticeable.

All "due" respect.... if you research Gorilla Glass you will see that it has nothing to do with "rugged". It has to do with if the material that contacts them is harder than the coating, they WILL scratch. Keys/etc are softer and in theory won't scratch it. However, many of the minerals in common sand/dirt are HARDER than the coating. So even a tiny bit of dirt can cause scratches. If you don't have that problem, then you keep an exceptionally clean environment, and/or the dirt in your area doesn't include those harder minerals.
Do not presume how another person does or does not take care of their devices. I am EXTREMELY careful with my devices. The fact is, gorilla glass CAN scratch. With my G2X, it was most likely when I was doing gardening and fished my phone out with dirty hands a few times, leaving dirt in my pocket that then scratched the screen. These things happen. Thus, you take precautions. You could either NOT ANSWER YOUR PHONE without washing your hands first - or you get a screen protector. The scratch on my Nexus 4 I have no idea how it happened. It happened right after I bought the phone, and is almost invisible but is there.
My devices tend to look in very good condition even after lengthy use. But even the smallest of scratches on the screen bother me as I'm a bit OCD about it.

Actually, I would like to believe that. However, the scratched up screen on my old G2X (Gorilla Glass) begs to differ with you. Within ONE WEEK of getting my Nexus 4, it had a small scratch on the screen. I put a screen protector and haven't looked back. My N7 now has a screen protector as well.
Thing is, they're scratch RESISTANT not scratch PROOF. If you're getting no scratches, then great. You don't have a source of sand made of harder minerals than Gorilla Glass. A lot of us aren't so lucky. Dirt around here apparently does have "hard sand" in it, so the slightest bit of dirt in my pockets, and the screen gets scratchy. Thus, screen protector.
Many people don't like screen protectors because of lousy installation. Properly applied screen protectors should be invisible. Getting one properly applied can be troublesome. I watched a friend of mine buy the expensive ones at T-Mobile and had the rep do it. He had no clue what he was doing, and tried to pass one off on them with DEBRIS under it claiming that would go away on its own. They made him redo it again, and the second time, the edges were damaged and ugly where he put his fingers all over it. I have properly applied ones on my phone & N7, and you can't even tell they're there unless you look closely at the edges.
Making a blanket statement based on nothing more than your own personal experiences that screen protectors aren't necessary is hardly scientific or valid. Maybe for you, they're not necessary. Some of us are a bit more OCD about not having scratches on our screens and choose to avoid that with screen protectors.

The. G2X had gorilla glass 1. The N4 has gorilla glass 2. The N7 2013 has gorilla glass 3. They made a huge leap forward with scratch resistance with version 3. Unless you're taking your device to the beach, there's no need to waste money on screen protectors.

Gorilla glass not tough enough on Axon 7 :(

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 ?

My wife's S7 edge fell a foot and the screen shattered in 2 places. The worst piece of **** I've seen.

A five foot fall onto a wooden floor would crack most screens unless the phone was in a rugged case.

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.

Pure tungsten is ductile. polycrystalline tungsten is brittle.

Interesting, I'm seeing tests on youtube for iPhone 6s and Galaxy Edge being drop tested without any major issue from as high as 10-12 feet. I will RMA it with ZTE but was surprised about it not surviving it this little fall.

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.
