What the hell is going on here?
I am unable to feel it on the surface of the screen so I assume it's on the inside, from an angle it kinda looks like mercury with a slight metallic look to it.
No screen protector on, the phone has not been dropped.
Looking for some answers on what it could be and if it's fixable.
Thanks!

SORRY DIDN'T KNOW I POSTED IN HARDWARE HACKING, COULD A MOD PLEASE MOVE THE THREAD TO THE CORRECT SECTION?
hello,
amoled display assemblies, like the one you have in your phone, are made by fusing together the amoled screen itself and a protective gorilla glass panel. They use a special UV reactant glue to secure the bond in such a way that when looked from above the glass cover remains transparent and the glue layer is practically invisible.
What happened in your photo is ..well, kind of unfortunate. For some reasons, the glue between the glass and amoled panels got damaged/unglued. It doesn't feel to the hand since it's actually underneath that surface of the gorilla glass panel. Unfortunately, i don't know any user DIY way to solve this problem. For what i did encounter with amoled screens, this type of damage mostly occures when exposing the display to high temperatures. This - coupled with some manufacture defects in the targeted area, results in this kind of problems.
Normally in order to solve this problem, the phone would need to be sent for repairs and it would either be exposed to UV light to try to reglue the panels or have the gorilla glass removed, replaced and the glue reapplied.
Please take note that some repair centers don't have this type of UV equipment and may suggest a display module replacement altogether. That's very expensive, about the price of a second hand phone.

Thank you so much for that very informative reply! :good:
I hope that my warranty will cover this.

I thought the galaxy s2 had gorilla glass? Got two tiny scratches on the screen, kinda pissed because the phone is so new there are no screen protectors available.
I keep my phone in a pouch in my pocket, I thought this gorilla glass was unscratchable????

Loads available .
Sharp object is the probable case of scratch but odd as its in a case .
jje
a key in your pocket might not scratch the screen, but some grains of sand for example can really mess with it.
even gorilla glass doesn't help against sand grains.
I keep repeating this... but you most likely scratched off some of the oleophobic coating, not the actual screen. It may look like scratches in certain angles or under certain light, but I bet you it's the coating.

So really hard glass covered by an easily scratched coating. If true, is there an easy, cheap fix? If not, then sounds like a screen protector is a good idea, even if the glass itself never scratches. Which kind of defeats the purpose of the Gorilla glass and the coating.
Nothing is unscratchable, unbreakable, unbeatable. GorillaGlass has the advatage of being resistant to the "usual" sources of scratching, but dust and sand are tricky bastards, that practically surrounds us and our precious phones.
When I first got my galaxy s, as careful as I was I still managed to get a few small scratches on it within the span of a few days. The only way to see them was when the screen was very clean and there was a direct source of light on it. Looking back it probably was a bit of sand or something sand like.
I ended up getting an sgp ultra clear protector. I would really recommend it once its out. But don't worry about small scratches. As long as you don't notice them when the screens on will be fine.
I think I'll end up cleaning my pockets religiously once I get my s2.
I think we all want to keep our babies scratch- and fingerprint free. With protectors, cloths and cases we make our best effords. On the other hand, not many of us keep our phones for more than a year (I had my SGS for six months before switching to the SGS2). So, for whom are we keeping the display in mint condition? The next buyer? I'm not saying that we all should throw our phones in pockets full of sand, keys and rusty nails, I'm just saying that common sense will keep our displays away from serious harm. To get annoyed over scratches that are only visible in bright, artificial light is probably not healthy.

I understand. I have a Gorilla glass phone and have always used a screen protector. Mostly because I read many user reports very shortly after the phone came out about getting scratches for no apparent reason. I can't know if it was the coating or the glass itself that got scratched.
My point was if they coat Gorilla glass with a more easily scratchable film, and you have to cover it with a protector anyway then the purpose of the hard glass and the oleophobic coating are both pretty much defeated. Unless you prefer to go naked, have less fingerprints and put up with the scratches. There really needs to be a coating that's as hard as the glass.
I use a protector because it's easily replaced, so new surface cheap and simple anytime I need. Without it scratches seem difficult and/or expensive to fix.
I agree. But it becomes somewhat ridiculous when we're just stepping up on the screen protection ladder. So, we have GorillaGlass, which is protecting our display from scratches. Then we're putting on a screen protector to avoid scratching the scratch protective glass. And just in case, let's put the phone in a leather case or a pouch, so not to harm the screen protector. It's like having sex wearing three condoms; you will be safe as hell, but the feeling and the experience will be practically non-existent.
I was almost certain that the whole point of Gorilla Glass was to provide a stronger glass to prevent the screen from breaking upon impact - say, dropping the phone.
I've seen a billion iPhone 3GS's with shattered screens (wtf teens?!!!?).
Gorilla Glass is supposed to stop that from happening. It will scratch as easily as anything else.
Thanks for the feedback, one question tho. I've read that you can get rid of scratches on glass using some Cerium Oxide paste, has anyone tried it?

Corning says increased scratch resistance is one of its features, as well as the break resistance you mention.
http://www.corninggorillaglass.com/faqs/all?page=1
"Gorilla Glass is better able to survive the real-world events that most commonly cause glass to scratch, chip, or break."
http://pdf.directindustry.com/pdf/corning/gorilla-glass-product-information-sheet/12631-67069.html
"High resistance to scratch damage"
But if they put an oleophobic coating on it the scratch resistance is nearly pointless. So you're rationale could make the most sense.
I agree that sand can really mess it up. My S2 has a scratch on the screen which can only be explained by sand from the beach. Even though I never brought my phone to the beach, it may have gotten inbetween my Samsung leather flip case somewhere, sometime, somehow in my shorts pocket.
I keep my phone away from small change and keys and all of a sudden, there is a small 3mm scratch near the middle to the right.
Honestly though? Everything about this phone is better than my old Motorola Milestone (which has been to many beaches), but the Milestone's glass touchscreen seems more durable.
So note to everyone with an S2 in a case: apparently sand can destroy the screen.
Wow i just noticed today ...I got the screen at the perfect angle of light & my screen is riddled with 1 inch scratches
I treat my GS2 like my baby ...it only goes in & out of my pocket
This is what made me to literally throw my iPhone in the garbage & I stopped developing for iPhone ...because of there marketing lies
I am developing a website to expose Samsung of all there lies ....it is probably totally true that Samsung endorses/pays/ gives people free devices to make YouTube videos .....To mislead people into thinking that Gorilla Glass doesn't scratch .....a crock of [email protected]%t !!
If I put my device in a series of angles I can see......mmmmmmmmmmmm 2 very, very tiny scratches. It takes like 10 min in proper light to spot them.
BTW: I did try to scratch it with a couple of keys back in may to show off; nailed it.
Actually rethinking ....I shouldn't be so hard on Samsung ...there maybe other factors involved ..that are sensible
& Corning/Gorilla glass is manufactured by Corning ...so it's not really "assumed" Samsungs fault for claiming that it is unscratchable !
But was wrong .....its Corning that claims there glass is unscratchable ...lol
Yes sand would scratch for sure ...but is it only sand !? ..or other rock particles ....metal doesn't seem to do anything ...maybe depending on type of metal ....winter road salt ?
Ehhm a key ..i think is way to blunt to scratch .....it could be from hitting the metal rivets on front jean pockets ...when sliding it out of my pocket ...but those are blunt also
Or so i either have sand in my pants or diamond particles :silly:
I found one big brown particle behind the digitizer. I wonder if there is any safe way to remove it. Do I have to disassemble the whole tablet?
I'm sure its not dead pixel because the brown particle is visible even if I off my tablet. Pretty annoying because it's almost 1mm in terms of width and length.
I wonder any of you guys out there have removed the display before. Thanks!
Most companies will replace a device for dust under the LCD glass. This is considered a manufacturing defect.
Does it really help to have a screen protector on STR? My nook is always inside a case, and always have some finger smudges on the screen, which does not interfere with reading the screen content.
Would it make the screen harder to use, such as in a resistive screen? I know it has IR technology, not resistive lcd, but it is good to know...
I have a screen protector, because I have cats and dogs who're lurking around my nook, and I'd hate to see them scratch the screen. I'm not using any case for it. The film does not affect the touch sensitivity in any way...
thanks for the info, emarusceac.
I can see dogs and cats and stuff being a problem. I just have an old NC sleeve laying around that works. If you can stand the wait, ebay is cheap Turns out the NC and NST width is the same...
emarusceac,
what sort of screen protector are you using?
Hi mh127,
I'm using a basic anti-glare screen film from ebay.
The nst is the first touch screen I have not used one on.
It is perfect now, the matte should hide small scratches, it gets used more lightly than phones/tablets, it is light (less damage if dropped), and it is cheap!
I am going to buy one.
I must warn you that it's VERY hard to apply it smoothly. I mean you'll get some air pouches caused by small particles, those bubbles won't go away no matter what you do. I prefer bubbles to permanent scratches though....

I ordered one. Was concerned that it would be tough to apply because of the high frame around the screen. Any tips how to apply well? You use a credit card to smooth the film down over the screen?
Oh one more thing. Has anyone tried removing one? Does it change or damage the screen in any way?
I have had several different screen protectors on my NST and none of them caused any damage when I removed them. I would note though that I have read that you must not apply a screen protector to the Glowlight, something about the built in screen protector and its light guide properties. I would also point out the one reason my NST has had multiple screen protectors is because they are so hard to apply without getting bubbles/lint between the screen and the film. The film I have on now I finally got applied without any bubbles/lint in the reading area, so it will hopefully be on there for a while. Make sure you are working in a CLEAN area and take great pains to get it lined up straight before actually applying it to the screen.
The NST doesn't need a screen protector, it really wont do much for the device, but if you really feel like spending the money for it go ahead.
The NSTG already has a protector built in, putting an extra one on would be like putting on an extra pair of latex gloves. It'll offer a little more protection, but it can get to be quite frustrating in terms of lost control. It's advised not to bother with a protector for the NSTG.
Personally unless you know you're going to have your NST in reach of creatures with claws, or lose objects with sharp edges the protective screen will do little for you. Even in those cases it's possible the screen would merely lessen the damage done rather than prevent it out right.
In regards to the NSTG and it's pre-installed screen protector, has anyone actually removed it? I've read lots of reports of people complaining about minor scratches and finger pressure marks causing the light to become very strong on those parts, wondering if removing the screen protector would fix that or whether it's instead a problem with the screen.

They claim there is one, I claim they lie as there is no visible edge of one. If there was you wouldn't get the light flares from minor scratches. Adding one may protect the screen but no idea what it would do to the light guide properties of the screen. If you ever have to remove it I'd worry what would happen to the light guide layer.
Because gadgets capabilities/sppecs increase rapidly & prices drop fast too, unless it's expensive I forget about screen protectors if the device is cheapish (got mine cheap) & if it will be outdated in a couple of years. Specially if it's not an outdoor device like my phone. Or if the protector hampers speed / functionality to some degree. Also personally I rarely scratch tab screens unless it's a phone, my phones/tabs all have protectors put on from day one, but not doing my NTSG. YMMV.
FYI, I thought this would be a good reference for people who have scratched screens. Original thread here. Has anyone found a better way to mitigate scratches?
a.mcdear said:
So my phone fell out of my pocket, screen directly landed on a rock on the ground. There was a nice scrape right in the dead center of the screen.
I found a product called 3M "Perfect-It III Trizact Machine Glaze", or otherwise known as "3M 06070". It is an aluminum silicate based polishing compound for removing swirlies from extremely high-gloss automotive finishes. The stuff is approximately $65 for a quart size from NAPA auto parts. For those who aren't aware, Gorilla Glass itself is an alkali-aluminosilicate, so this particular polishing compound is chemically compatible with the material the screen is made out of.
**Apparently Rezound is NOT Gorilla Glass (confirmed by Corning & HTC) but must have a very similar composition**
It works absolutely beautifully. I started by applying it with a polishing cloth and rubbing by hand, but I switched over to a polishing cloth Dremel tip in my cordless drill at low speed. Approximately 45 seconds worth of polishing the screen with the drill and scrape is hardly noticeable now. With a little more careful work, I believe it will be completely gone!
Unfortunately its expensive. $65/quart is really not that bad though, when you consider that most polishing compounds that are sold specifically for glass screen repair cost as much as $30 for 8 ounces, and in my experience are less effective than 3M 06070.
I hope this helps anybody with a damaged glass on the screen. Best bet is to just get a screen protector. Not having one is a potentially expensive mistake..
**NOTE**
While this does work on the Rezound, I would NOT attempt this on any other glass screen unless you can verify that it is real Gorilla Glass or some other aluminosilicate glass.
Alternately, if you prefer to simply replace the entire glass/digitizer portion of the phone, I have found one available online (for cheaper than this polishing compound too!) here at this site: http://www.gogotoshop.com/product_info.php?language=en¤cy=USD&products_id=4896

If you applied it to the entire screen, would it even out the texture, even though it will "dull" out the entire screen? And how effective is it at removing scratches?
Like voluptuary said Lumia have that 3 layer anti-glare and anti-smudge coating on top of gorilla glass. Lumia's screen scratch resistance is really very poor because of this. In general it is very resistant, but sightless press with sharp edge will leave a noticeable mark.
As far as I know there are no cheap solutions. If scratch is really huge and annoying consider replacing the whole screen.
I managed to scratch my Nokia in 1st day of use by simply putting in pocket with keys. Never happened to my other phones (HTC Hero and Polaris).
I tried jewelers polish powder, aka cerium oxide. It worked pretty well for very light scratches, but deep ones are still visible. I used electrical drill and polish for about 1hr at 1000rpm speed. Just watch to not to overheat screen or it will break.
As a finishing polish I used Displex. All it does is applies protecting coating and removes all left over marks from cerium oxide. It's poor mans choice, don't expect miracles.
Also any kind screen polishing will reduce effectiveness or even damage that anti-smudge effect. So be warned.
Hi ist this actually the best glass polish?
Is this 3M "Perfect-It III Trizact "50077" or "06070" from 3M?
But there is also "3M Glass Polishing Compound" with the type number "60150".
With all the complaints of just glue around the edges of glass screen protectors, especially the curved edge to edge ones, has anybody though about trying to find and apply their own? I did a quick search for glue or adhesives for screen protectors, but all I could find was glue to replace actual screens, which were permanent bonding type. I'm thinking if you could just buy the adhesive yourself, apply to the whole protector, then pretty much all the pitfalls of current crop of tgsp for the op5 go away. Thoughts?
From what i understand it's a very thin layer of silicon.
Applying it in a way that keeps it invisible is the trick.
I've had similar thoughts btw

Trying to source the right one of those might be the best bet.
I haven't been through them all, but a transparent under 200um would be best.
tesa 61360 is 100um thick.
Tbh I wonder if a 5mm wide tape would be better than full screen. But I guess there's tapes wide enough to do all the screen
This is a really bad idea, these protectors are manufactured in a factory, if you go looking for some kind of adhesive and try apply it yourself it's just gonna look terrible, it'll probably be too thick, the screen won't be responsive enough and it'll be uneven. Forget it.

I didn't realize it was a strip of silicon. I was thinking more along the lines of some sort of spray adhesive. Low strength, optically clear of course would be ideal. Applying a strip would indeed be a bad idea.

Those are the very strips that come on screen protectors that people don't like though, the full face adhesive protectors are best as they don't let dust under the edges as much and don't have the rainbow effect, the protector only being adhered round the edges is the reason people get that rainbow effect.

Unless you get a sheet of that tape to cover all the screen..
My initial thoughts were just a slightly wider strip than the usual. That should give a better deal than what we've had so far..
I've seen something like this for the S8. whitestonedome.com protectors that fit perfectly.
They use a uv adhesive. From what I can research, the type of glue is called LOCA - Liquid Optically Clear Adhesive and needs a UV light to set. Now, I found one type called TP2500 that is somewhat cheap. But it's supoosedly used to bond the LCD screen to the glass during repair. I have no clue about the bond strengths involved and I wouldn't want a TSP permernantly bonded.
But then, heres what I'm thinking. I've seen Chinese TSP that overhang the curve sides slightly, but they offer a sealing liquid to "patch" that. And that sort of works. But from what I see on the reviews. It fails after a while. Weeks to months later the gap reappears. Rinse and repeat. Could we use a LOCA with a sensible bond strength to patch the gap until the time we want to remove it? Pretty much a poor man's version of whitestonedome.

Glass camera lens assemblies are glued together with a UV set adhesive. It is not a trivial task to separate these elements after bonding but it does make a bubble free bond and remains workable until hit with the UV. a search for camera lens cement should find several choices. Before high tech the lens elements were bonded with a balsam adhesive which also works.

I saw the loca glue, but from what I understand is that it is more of a permanent bond. I'm sure it would work well, but would probably be more trouble than it's work to remove it.
This might be worth looking into. From what I can tell, it's a a sheet of double sided optically clear adhesive. I can't find a listing for oneplus 5 and I haven't taken the time to see if any other phone models have a similar sized screen. Maybe something like iPhone 6 plus and then trim to fit?

The OCA tape is supposedly the more convenient cousin of the LOCA that's also used to bond lcd to glass. I would assume the bond strengths to be similar. Just less equipment required.

The videos available for the whitestone protector show that its possible to just peel it off. Considering that they also use a UV curing glue, I would suspect there is a low bond version LOCA. Or the lcd is just that fragile during repair that the special tools are required. More Google work might get some answers on that.
I did find the bond strength for the TP2500 though. 0.3 N per mm2. About 3kg per cm2. No clue if that is strong though since I have no frame of reference.
Moar digging.... There has to be a way to get the TSP to work on our phone...
