Gorilla glass is marketing at its best - Galaxy S 4 Q&A, Help & Troubleshooting

Hello. I have managed to scratch my precious S4 screen just after using the phone for a week. Yeah I do have a mild case of OCD (at least what I think is mild ) considering that I do use a pouch for it I wonder what is the point with all those videos showing off the impressive Gorilla glass x. Of course the second I noticed it I applied a screen protector. So much for Gorilla glass..

If you want a pouch....buy a kangaroo.

As everyone will tell you Gorilla is scratch RESISTANT NOT SCRATCH PROOF.
The ads that demo how tough Gorilla glass is show them using coins,keys and knives on the screen mainly. These are "softer" than the layer on the glass so it doesn't scratch.
Sand however is very "hard" so it can easily scratch Gorilla glass. If you got sand in the pouch and it rubbed on the screen it will definitely scratch it.
It's actually a very good product and is more resistant than other glass but it isn't indestructible and the manufacturers don't claim it to be.
Sand is a screens worst enemy.
P.S Why did you post this in Q+A?

Had my S4 for over 6 months with just the case in the picture. I check my screen every now and then for scratches and marks. I literally can't see a THING on that screen and it's very impressive. I'm pretty careful with my phones but my last phone, HTC Mozart, had a much softer screen. Seriously, you might be used to it now but old displays were a LOT more sensitive than these new screens...

Dropped mine with no cover on concrete twice. Landed screen down both times, no scratches, no issues at all. What did you do to the screen? As said above it's scratch RESISTANT. Sand and other abrasive substances will scratch it. Sand has eroded land masses over time when you think about it.
I always have to ask this as there are a LOT of clones about, is your device a real s4?

Screen easily scratched?

Anyone else notice that their screen is easily scratched?
I think I'm pretty careful with the phone and not have it in my pocket with other items like keys, change, etc. but I already have 3 small scratches in a little under 2 weeks. I was hoping to wait for a static cling screen protector but I'm thinking I should just get a wet, Invisible Shield, type one in the meantime since it seems to be easily scratched.
Is there gorlla glass? That's why I didn't buy a screen protector for my epic 4g, but I ended up getting scratches even though I keep it away from keys and change and stuff.
Apparently, fine particles of sand, quartz, etc can scratch the screen,which is bs because my hero got ONE noticeable scratch, and that was only from when I dropped it in the train tracks.

It's glass, so no. Nothing in your pocket should be sharp enough to scratch glass, including your keys. Plastic will scratch easily though.
No gorilla glass on the nexus s
I'm looking to get a screen protector too but just not sure which to go for. I usually go for the £4-5 ones from ebay but I'm guessing that's not going to be good enough for the nexus s.
I haven't seen a lot show up yet on the market and those that have don't get great write ups. Seems a protector is a must though.

You sure its glass? The Nexus S or the Hero you're referring to?
I never trust a screen on a mobile device, which will inevitably be dragged across and impacted by many things over its lifetime pretty much regardless of how careful you are (sharing pockets, being pulled out of holsters, being dropped, et cetera), to remain pristine when left as bare glass/plastic.
I know so-called gorilla glass is supposed to be extremely resistant to scratches, but if you want to be able to polish off your device and not see any defects on the screen after months or even years of normal use, I really think it's wise to invest in some sort of screen protector. Which one you have is less important, since any incident that punctures your screen protector is pretty likely to break your phone entirely (unless, like the people at Zagg, you enjoy taking a router to it).
the nexus s DOES NOT HAVE GORILLA GLASS.
that is 100% confirmed, there is no gorilla glass. However, the screen itself is glass, not plastic.
With that said, a screen protector is STRONGLY recommended as it is just normal glass and not gorilla.
The curved screen is suppose to help against drops, so if you drop it the entire screen won't hit the ground, therefor it shouldn't crack, or get scratched as easily.
Honestly everyone should buy a screen protector or invisible shield for their device, or keep it in a case/pouch
My captivate has gorilla glass and I have no scratches in the glass. I do not even worry about putting my phone in my pocket with my keys. I hate screen protectors so gorilla glass is a must for me. I don't understand why they went with cheap parts on the nexus s but google did the same thing with the n1.

nexus s has gorlla glass....100% http://www.androidcentral.com/gorill...o-korean-style
but i got scratches only on back cover......don't like a quality of plastic !!!!!!
Even if the Nexus S does have gorilla glass (I have no idea if it does or not), wouldn't the oleophobic coating on it be vulnerable to getting messed up regardless?
My Nexus One is seven months old and there's no sign of any scratches on the screen.
According to this post Nexus One doesn't have Gorilla glass: http://www.google.com/support/forum/p/android/thread?tid=3bc418e9a4869ba8&hl=en
What I want to say is that the Nexus S can be up to Nexus One's scratch resistance, even the lack of Gorilla glass.
No Gorilla Glass on the Nexus S. I don't have a single scratch on my N1 after a year. My Nexus S got a scratch within a week. I think its less scratch resistant. There is a video on youtube of a guy trying to scratch his N1 with his keys unsuccessfully. I am usually always super careful with my phones but I think the curved screen got caught on something. Don't leave it to chance - if you're worried, get a screen protected.

If you think your gonna get it hurt, by a screen protector, even a cheap $3 one will save your screen.
If your really worried, go all out and get an invisible shield.

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

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 ???

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.

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.

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

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.

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
Don't understand why more people aren't using tempered glass screen protectors
