I've found something odd with my screen, and although I intend to do an exchange on my S3 I figured I'd share it here to see if anyone else has seen it too.
What it seems to be is that a couple chunks of pixels go entirely black when their section of the screen calls for being black, while the rest don't. I'll try to show you what I mean:
This is a shot of my screen, running a screen test app on an all-black image. It's extremely hard to get a picture of a dark screen in a dark room with a cheap point-and-shoot, and you'll have to ignore the stuck pixels on the camera's CCD, but the red arrows point you to the bits in question (I've also turned the contrast all the way down, and brightness all the way up, in photoshop because otherwise the spots weren't very clear... and still aren't in focus... but in person these are easily visible as two dark spots in an otherwise gray background when you look at the screen in a dark place). You'll want to view it at full size, and again I'm sorry the image is so blurry but viewed in person the "blobs" in the image are in fact crisp edged vaguely tetris-block-shaped pieces of total blackness surrounded by dark gray.
For comparison this is my girlfriend's Sprint S3 screen shot with the same camera under the same conditions and with the same photoshop effect applied.
If you want to see if yours does the same thing, download "Screen Test" from the market, turn the screen's brightness up all the way, change it to the black screen (the second testing screen), then go into a totally dark room. You may have to look just off to the side of the device to see them at first, but once you've done that and seen the spots you can't un-see them.
Lest you think I'm being overly picky (although I would argue any defect in a device I paid $550+tax for is one defect too many) it IS possible to notice this even under normal usage conditions. I kept seeing a spot on the Facebook app every time I would reload a page, and every time I thought a piece of something had gotten onto the screen, but before I could wipe it away it had disappeared. It may be a minor annoyance, but it really bugs me, so I'm going to exchange it. I figured I'd document it before I did, though, just in case anyone else had seen the same things.
A lot of people have this issue, including me. But since I literally never see it unless I'm using Screen Filter at a low percentage, it's not much of a bother.
The only time I see it is when i play draw something.
Screen blobs....
They have plagued Samsung screens for a while now.
The sad part is.. from my experience with the blobs, Even with a device that doesn't have them they eventually show up.
Found on the following
My s3
Galaxy note (over 6 tested)
Galaxy s2 (a few tested)
Galaxy s2 skyrocket (over 6 tested)
Even the galaxy note 2 I recently examined
They all have them

My search led me here! I myself noticed this tonight while I was watching Underworld Awakening in my bedroom with the lights off. I have a nice blotch on the center right and a few spots scattered throughout the screen. Looks like I will have to unroot and watch this out:/ what a pain.
Here is my screen shots may be hard to see from these pics.l but its definitely there.

I haven't seen this mentioned anywhere else. Does your ET show (mostly) vertical streaking/unevenness when displaying a solid, light color? Is this something related to AMOLED, or is my ET defective?
Edit: I just realized this is dependent on screen brightness...the streaks are only apparent at the lowest brightnesses.
Thanks.
Screenshots would help others see what you're referring to.

I get this when my screen goes off and on
Sent from my SPH-D710 using XDA App
I have to mention that the first one i had, was like this, but it showed like a dark spot in the center of the screen, btw screenshots wouldn't show this problem because is actually the hardware" Screen" In this case.
So i went ahead and brought it to the Sprint Store where i bought it from, and asked for a replacement due to the Screen hardware defect, they kept *****ing at me telling me, that they have to keep it for a whole day, to do "Tests" Im like... well its a hardware issue and i have taken the phone and hardreset it, making the phone as if just out of the box, and showed them the problem again"btw the phone comes with a Gray and Green pure colored background images that you can show to them, that it isn't an Image that you had Altered" , and they can see that it is the screen, and its what i showed to them, and thats when i got my replacement, When i got this one, i saw it again, and it had a white spot... also had various streaks coming from the Top of the screen, went int he second day and got me another replacement, but before i left the store, i stayed about 30 minutes in there, testing the phone out, and downloading all the apps that i had in the phone before. Also Good way to notice this problems( defects ) is dimming the screen all the way, and changing the background to gray, which is a default wallpaper.
This screen didn't have any of the defects that previous ones had, so im a happy camper .
So now what i'd recomend if you can, is replacing/exchanging the phone until you get one with a decent screen.
I get this too when my brightness is turned down. It's most visible on grays. Like the background of the market. It only appears when the brightness is turned down low. There is also this app in the market called "screen test" which cycles through different solid and colored backgrounds. that if you did take it in you could show them that. This issue doesnt really bother me but I have TEP plus there is a one year manufactures warranty so if it gets worse I'm not worried about it.
I finally got around to taking a quick set of comparison pictures. Sorry for the poor quality, I took them quickly with my phone. I also tried to purposely take them out of focus, so moire patterns from the actual pixel grid wouldn't confuse things. I have a feeling this is how all *LED based displays are.
I use the app "Colors" to quickly get a solid patch of color. I encourage a few people to download it, and browse through a few colors (grayish or dark tones - light or bright colors aren't affected as much) and see if they have it. "Grr-ey", "Mighty Slate", "Kind Giant" are good ones to test with.
Things are much more noticeable when the brightness is set low.
Brightness manually set to minimum:

You may be right my screen has the same effect :-(
Sent from my Galaxy SII using XDA App.
My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.
unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that
All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.
Im quit perplexed about this so if someone with experience can explain

i posted this a lot before but i want to know, there is some grain visible in bright angles, and actually i have two of those white spots visible at angles, one of them is pixel size the other as you can see in the pic is quit few pixels size
but it doesn't show on black, very minimal on blue, shows on every other bright color
whats is itexactly, a dead pixel would be black and appear on white, a stuck pixel would be white and appear on black, dust would appear under sun light or flash light when the phone is turned off
but its not any of those, is this imperfection to the screen glue or dust in the glue or back light bleed?
The grain i assume is just glue imperfection but this white dot is driving me crazy it's mid screen and ruins the nice view angles of the One X, the screen is fit well actually
I tried pixel fixers but no luck, right now i'm trying to leave JScreenFix running for two hours
I have one of these, I think it's just a hot pixel. I emailed Clove and after seeing a photo of it, they said HTC won't replace for one bad pixel. Same thing as yours, only visible on white screens at odd angles, can't see it when looking at the phone straight on, and can't see it all on anything other than bright colours. Wish it wasn't there, but it's not a big deal to me, the rest of my phone is fine. Let me know if a pixel fixer works for you, haven't had luck so far. But I haven't noticed it lately.

a typical hot pixel should appear on all the time even dark background, anyway no luck with JScreen except that the device crossed 55degree lol
Got the same issue. Send it for repair today, it bugs the hell out of me. If they wont replace my screen for i'm gonna ask a refund.
I just noticed that I have one as well. Not sure what to make of it really, could be a lot worse but its pretty peculiar. Anyone managed to shed some light as to what it is or been able to remove it? Or if HTC will repair it?
I have one in the middle of my transformer prime, irritating but prob the least annoying type of screen deffect. Only noticeable on white backgrounds

Hi,
So 3 days ago I bought the galaxy 3 (new from a private store) and there's a really weird problem with the screen..
U can see in the picture I added the "C" like shape and the dot underneath it..I'm seeing it when I play games, use the camera and so on..It's there all the time but its visibility depends in what the screen is showing.
If u know how to fix it without me having to replace the device..your help will be most appreciated.
Guy's I just transferred the pic' to my computer and the "C" shape+ dot wasn't there (meaning that the problem is in the internal side of the screen)so I took my old SGS1 and shot the SGS3 screen
How can a new member upload a picture???

You know, I have some some shadows on my screen as well. They are only visible when I'm looking at the screen in low ambient light... So I notice it if I'm watching a movie at night in the dark, or, as you said, taking photos in a dark place.
The shadow looks just like if you push on a computer's LCD screen... I wonder if the Gorilla Glass covering is imperfect and pushing on the screen?
In my case it doesn't look like a pushing problem, it's way too symmetric and there's no "pushing waves", the color is not consistent with the "pushing effect"…
I don't think there's something I can do about it except replacing it…it's funny because I really have no clue what on earth could cause this…
Upload it to imgur then post link.
That's a know problem, rare though.
I have one little line on my phone only visible in the dark on a black background.
I think it's called ink spot or something like that.

hey there guys. am having multiple issues in a 1 week old Note 2 which i noticed very recently.
first issue being , strange fade outs near home button, (tried cleaning screen with everything from water to specs lens cleaner,it's a permanent thing..... and looks like it is under the glass )

Second issue is non-aligned fade outs on front cam and sensor
third issue is , there are few pixels on left side of screen that do not blend in with other black pixels around them(except for videos where color is similar to pull down menu on home screen).it doesn't move either.it's in a permanent location. it can't be seen under proper light and only appear on more or less lowest screen light setting with ambient light off.this issue however doesn't occur with any other color of video,they blend in perfectly.it's similar to note 1's black crush issue,but on a specific spot
sorry but this is the best pic my cam could get. you have to look very carefully
Last issue is, S pen doesn't work on lower right side of the screen. like on the very end in the corner. it works fine in other 3 corners.
I know i sound extremely paranoid.... but i love this device so much ! would love perfection. should i take it to service center? will be pretty darn hard to explain the issues though. and can i expect a replacement ? on the side note, i got it from India and no carrier.
Thank you for reading

Hey,
I dont have ANY sort of fade outs anywhere. You should definitely have it checked. As for the S pen....even mine doesnt work all the way down to the end on the lower right but does go to the end of corners of remaining 3.

and no ... no screen guard is on.it's whitish cuz of moisture and oily hands,can't help it in India's climate and tired of wiping the screen every hour. but those fade outs are permanent thing.
i do plan on getting screen guards soon after taking it for warranty though.
