Weird scratches beneath the screen

DAMN IT!
Got some weird scratches/marks beneath the screen.
It's only visible in low light surroundings, and on a black background, but it's very very ugly.
When I made this thread a few similar posts came up.
Apparently it's a known problem on the S2 and note too http://forum.xda-developers.com/showthread.php?t=1335423
I can't make a picture of it right now. Will try tomorrow.
Somebody made this to explain what it looks like.
Mine is like this, but much worse

I'm going return it tomorrow, and hope they give me a refund, so I can buy another one straight away (and check it off course). And hope I don't have to wait for 3 weeks for the repair/replacement

Is it there when the screen is off?
If not then it's not scratches. I think its an AMOLED thing. I notice it when my SGS2 freezes on a black screen. But not there when powered down or back up again.

Exactly. When i first saw my sgs1 under direct sunlight i thught that was broken. Later i discovered that the lines ias seeing was the circuitry under the screen. You can see iy under direct sunlight when the screen is off.

I don't see any spots or ink marks on my GS2 at all. But seems like a lot of the GS3's are having these spots.
Some have exchanged their phones for those with a lot less of of those markings.

It's only there when the screen is on, but it's actually visible in daylight now I know it's there.

I read somewhere that this is a residual issue caused by the bonding glue they use t to attach the glass, they should fade as the glue dries, but keep any eye on it and nuke 'em if it doesn't!

Yeh galaxy nexus has a similar thing its the amoled display some of the pixals are not turning fully of, I think that was the conclusion .
But only noticeable in very dark room with the screen black and when your eyes adjust. Could be wrong without a pic I can't say.

I think its an inherent flaw with AMOLED panels. It looks like patches of the screen do not go as dark as the rest of the screen.
Some screens are brighter than others in general though, among the same phone. This Nexus was brighter than another one I had at the same time, at both lowest and highest settings, and had less black dots on black screen, presumably because the screen was brighter overall.
Doesn't mean to say I won't check for the problem before I purchase though

Well I exchanged it for a new one.
This one is flawless
I'm glad I bought it in a physical store now vs online!

Yep I have the exact same thing with my SIII but not as bad as yours. What did you do about your SIII? Did you return it? I notice it mostly on a black background whilst watching films/videos mine isn't really that noticeable on my SIII but still pretty annoying.

DSLR Photo Illustration of visible screen burn + ink marks issue

Hey xda members,
just had a bit of spare time so I decided to make some photos of my GS2 while displaying a totally black screen.
Normally you can only see these "effects" when you're in a completely dark room while looking at the GS2 being the only light-emitting source through its display.
Note: The actual purpose of this thread is to educate those people who can't imagine what burn-in/ink marks look like in reality. That's it, just plain visual information.
So I hope this isn't an issue even if there may already be a similar thread
I made some of the photos with the roomlights turned off and others with a very dim light.
The photos were shot using a Nikon D3100 DSLR with long exposure/high aperture settings.

As you can see in the first photo (below), even if the GS2's display shows a completely black image, which should result in a black display (OLED = pixel off) it shows weird marks and still emits a tiny amount of light.
In the second photo I have marked all the relevant weird spots (including screen burn-in caused by grey status bar [see below, marked by arrow])
The OLEDs in the burn-in area seemed to wear out faster because of the static grey shade it was displaying all the time thus resulting in this permanent color change in the affected area.
This burn-in was apparently caused by this theme which I was using for several months. As you can see, even the status bar in a dark grey shade can cause burn in.
A couple of more photos (with different white balance):
See below for photos in full resolution:
Hope this helps in any way and gives those people an impression who can't really imagine how screen burn-in can be caused and how these display issues (ink marks) actually look like when you capture them properly.

Very interesting indeed. Thanks for the great images, it's certainly an eye-opener to one of the main drawbacks of S-AMOLED screens.
Regards.

Roughly about nine months, bought it in October 2011.

Hope this is no news? Every AMOLED burns in (like crazy). Been doing that since the first models were on the market.
Every SGS2 has it, whether people say yes or no. On my SGS2 it was clearly visible after around six months. Knew it beforehand so it was no biggie/surprise.

Yeah, also knew it before buying but I never thought the burn-in would look like that so I thought I'd share my experience with the world
While it does look pretty bad on the photos, you can't really see these issues when the screen is turned on with decent brightness, so it's no issue for every day use, but it would be interesting to know how the burn-in looks like if you use your phone for example 3 years.
Still, it looks already really horrible after 9 months of use when you look at the photos. I hope the OLED-technology makes a giant leap forward in the next years so one day these display issues will be a thing of the past.

thanks for the images, i find it disgusting to have that burnt in on a topline expensive phone in short time.
this is my first amoled phone so i dont know what to expect after a year or so, its bad for those who keep thier phones long term, would like to see how the screen is in 5 years time
is it bad when you watch a movie?

Well, it depends while watching a movie. Sometimes I can see the burn-in in movies with a lot of dark scenes, in other movies this issue is not apparent.
Either way..since I discovered this issue, I cannot ignore it anymore which doesn't mean it annoys the hell out of me but still it's a pity to see the phone 'degrading' already after not even a year and spending a lot of money on it.

Screen burn in

Within 3 days of owning the note i have burn in already how is this possible. when the brightness is on the lowest setting and your on a screen with a black or grey background you can easily see back scribble marks all over from when i was in s note just drawing lines everywhere playing around. Its not like i drew them and just left the screen on for a day to burn it in either

The best thing you can do is go to the service center or return the phone where you bought it.
Samsung Service is really good and they replaced my hard bricked Galaxy Ace's motherboard for free under warranty.

i asked amazon but i dont want to return it and be without a phones for 2 weeks. they told me i should buy another one then return this one for a refund. the notes on amazon are not fullfilled by amazon now so if i get one through another dealer and theres a problem i just dont feel like dealing with them for a refund

Well, even if you returned it to Samsung for repair, you'd be without it for a few weeks, so your choice really is quite simple.
Put up with it, or return it.

R U sure its burn in..its look like "screen bleeding" to me..
Sent from my GT-N7100 using xda app-developers app

daft suggestion but have you tried cleaning the screen?
it doesn't "burn" like a crt so you shouldn't see it when dark if there was a problem.
could it just be grease marks?

yeah its not the screen its clean as could be. i downloaded a screen burn-in tool and when it cycles through the colors and gets to red. u can see where the marks are but there blurry almost like they were bleeding. but all other colors u cant see the marks. but if i open up a black screen and turn the brightness down u can clearly see the black marks from when i was just scribbling lines on s-note. its def in the screen its not marks its burnt in

heres another pictures taken in the dark with a greyish background with the lowest brightness

Don't worry about the black dots, because that's a common problem for amoled screens. I also have it on my s3 that I have changed 4 times because of this problem. But sometime you can be a lucky and get one without this issue.

Ink spots in S4 ?

A friend of mine used today a S4 and says it has some Ink spots.
Anyone else have Ink Spots?
.

You mean like these on the SGS3? I'd be surprised if the SGS4 didn't have them. The N2 did. My N2 may or may not have them because I've never looked at its display on a solid grey background with brightness turned down to zero in a dimly lit room as I don't typically use my phone on a solid grey background at zero brightness in a dimly lit room. There are always multi-page threads in every Galaxy with a SAMOLED display's forum talking about the "ink marks." Yet other then in the situation I described its never affected anyone in everyday use. People that this is going to freak out shouldn't buy a SAMOLED display.

What Barry said. Those blotches are pretty much standard. If you go "looking" for things, you could see backlight lines on perfectly white backgrounds on LCD too if you're REALLY looking for it. The thing is none of these are even nearly noticeable on daily usage. And neither do they interfere with your usage tbh.
That said, if you're buying the phone to view an entirely black image in a pitch dark room with low brightness, then avoid any AMOLED devices

GS4 has greatly reduced DC Bias. Much better contrast than the GS3 and Galaxy Nexus.

I remember having them on my old SGS3. Really annoyed me so I feel your pain.

It's called "mura" and is present on every Samsung device I have owned (GS2, Note, GS3, Note 2)

Yep, every single SAMOLED device, Samsung or not, has it AFAIK. Degrees might vary, but it's there.

There are some members saying that apparently applying heat reduces the effect, not even gonna try it though. It is not that noticeable on my Note 2 even on low brightness/pitch black screen on pitch black room. S II users were the ones who had real torrid time with blotches.

Yeah, definitely don't try this. Can't remember where now but someone had this complaint about their Note II and went and used a heat gun on it. Suffice to say that "tiny annoyance" turned into a "I've got to call and get a replacement and this is going to be an awkward conversation". No idea if he got it replaced under warranty or not.

I didn't know.
Now i'm well informed, and will buy my S4 on May. :laugh:

I've had that on my SGS2, the screen was gorgeous so no worry.

I don't think even there are some black spots, anybody can recognize them
The black on S4 is tooooooooooooo black, much much much deeper black than Note 2
I can still see the luminance on Note 2 in dark room, not S4

Edge Viewing angle issues?

So after a few days of use, I started noticing that I was unable to see the "People Edge" tab on the right side and while reading pages that were not exactly black in color, it looked like the 'edge' part of the phone looked as if I was looking at a TN panel sideways... So I compared this to my wife's phone and sure enough, it's a problem. On max brightness, I definitely don't get the same colors or anything of that nature, and it's significantly "bluer". Here are a few images for your viewing pleasure. I contacted the local VZW store and they said they'd exchange it once it comes back in stock (within my 14 day period).
** Note ** I did mess with all display settings and the color issue is not correctable.

You'll see the greyish look to it on the edges.. it's driving me freaking crazy. I paid $800 for a ****ing phone so I'm being picky.
If any of you guys are having this issue and within your 14 day grace period, return it and get another.

You're wasting your time if you return it, because the new one will have the same thing. It's a limitation of the design. The only difference is that on some phones the edge "shadow" appears more green, more blue, or more pink.
My S6 Edge had it and so does my S7 Edge. You'll stop noticing it after a few weeks.

My wife's does not have this issue at all, so I don't think that's true... if the one they exchange it for has the same issue, I guess I'll eat the $35 restocking fee and never own an 'Edge' phone again :|

I have never seen an "Edge" phone without this to some degree, but chances are you'll end up with it on the exchange device. Just go look at the demos in the stores
After a few minutes of Googling I again found the official Samsung article explaining this. Took me weeks to find last year when this issue was driving me nuts..
http://www.samsung.com/za/support/skp/faq/1076253
Your device is not faulty. The colors on the curved screen may look different depending on your viewing position.
The slight green tint in colour at the edges of the Galaxy S6 Edge display that you may observe on occasion is due to a phenomenon called WAD (White Angular Dependency) which is due to the inclined curved surface of the S6 Edge screen.
For an AMOLED display, the WAD phenomenon results in the colour white sometimes appearing to have a Green tint, or on occasion a Blue or Yellow tint when viewing the AMOLED at an angle. But when viewing directly from the front or side the colour will be as expected.

Same applies to S7 Edge.

Interesting, thank you very much. Yeah, guess it'll just be a return.
I'm very peculiar with my eyes. I can't wear glasses with my astigmatism because of the odd shapes I see so I doubt it'll just go away.

I would encourage you to do the exchange and see if the new one is slightly better (the tints are all a bit different). Maybe it'll be less noticeable? But then again, the new one might be worse to your eyes. It's a lottery
