[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.

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.

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?

Gorilla glass- good stuff?

So, any thoughts about gorilla glass? Today my 2week old dvp shattered. Yes, I dropped it. But, I've dropped phones before with no damage .
I ordered s new one while I fight to get a replacement. Low expectations on that. However I'm thinking my expectations on gorilla glass may have been too high.
Anyone with s more correct expectation level willing to reset mine?

technically your gorilla glass didnt shatter you had a bad drop and the glass layer under the gorrila broke. trust me ive taken a hammer to the top layer and nothing. if you drop the phone with the screen facing down then your ok. but drop it on the sides or the back and you can get the layers under the gorilla to break

no, it shattered. Top, bottom, and every layer in between. I cut myself on the pieces falling off. I do have a pic I'll share later. I thought it landed face down...loohed like it. But the break pattern indicated more towards the edge. Funny thing though, I was also holding my hd2 at the same time..both dropped togethr. One on top of the other. Both broke, indicating the drop was similar to what you day.
The Dell shattered completely, inner and putter layers. Only a tiny part of the screen is alive. The hd2 has cracks, but is usable.

I dropped the phone glass first on a pavement, it had a screen protector. Though the screen didn't break nor are there any scratches but it did get a pin point dent on the glass
I guess if they are not sure about the amount of RAM they put in this phone who is to say if this is a real gorilla glass.
Just curious, the hammer thing you did, was it on a DVP?

I read an article somewhere that said that gorilla glass is only strongest when it is at the center and it is not as good at the edges.

I've seen all Gorilla Glass demo's done hitting it in the middle. I've seen just about every single break happen because of edge damage.
This should be addressed IMO.

My DVP has scratches all over the screen...Scratch resistent my butt..
Good thing I'm getting my replacement today

i keep my DVP in my pocket all the time and the glass doesn't have a single scratch.

personally i got one scratch from keeping it in my pocket and several scratches from this one time where i dropped it
and engadget had several scratches on the venue
so some people get lucky and some dont as far as gorrilla glass goes

I had the displeasure of owning the DVP and thought the glass was atrocious. The curved design made it hard to scroll smoothly. And godforbid you try and wipe away smudge prints and dirt - this was a task in itself. However, I dropped it face first from 1 and half feet and not one scratch.

I abuse my phones and the best to take my abuse was my Dash 3G. The DVP is comparable. Only 2 light scratches and i got my phone a week before christmas and did i mention i abuse my phones. They are kept in my pocket with keys and such. Even the chrome trim has held up nice. As for the curved glass i like it.. Very tactile, and easy to use. maybe its my big hands but I like it, even the keys are spaced well and robust. Again, i have huge hands and the on screen keyboard doesnt work for me, but the portrait works well.

I've dropped mine a few times, not a scratch. Just yesterday, my car holster decided to let go of the dashboard, causing the DVP (with a little extra weight attached) to faceplant into my shifter pretty hard. No problems there either.

got my phone a few days ago, dropped it my first time today and the glass shattered
what can I do? I am very disappointed in myself....
I cannot find any replacement parts, I cannot find any repair shops for it... should I sell it as is, or call dell? IDK what to do... it still works fine just has a very ugly screen

a cracked screen is considered out of warranty (I think it also includes any physical damage as well...not sure about that part though)

Well no one ever said Gorilla Glass wasn't glass... It is tougher than normal glass against scratches, but it isn't scratch proof nor is it shatter proof.
Remember it is still glass and that means it will break under the right conditions.

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.

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.
