I got a replacement phone because the headset speaker died on my original one. I don't remember having this issue on the original phone. Can you guys take a picture of a white wall or ceiling in medium light and see if you have this problem. Otherwise I might have to see about another exchange.
Also, it seems that this has been a problem since the i9100 was introduced but I don't remember it before.

that's a light issue, not a camera issue. turn your flash on. besides, when is there ever a time that I need a picture of the ceiling?
(by the way, I checked this on 3 phones, the ones in my signature, and it does it on all 3 phones. Then I turn on my flash on the gs2 (since the other ones don't have a flash) and it goes away. in order not to get it without your flash, you have to be in more natural sunlight)
You've never taken a picture of something white before?
The ceiling is just an easy example.

I have, but if it's outside I don't get this red spot. And if it's inside, I don't get it either if I use the flash. I don't see that as a bug in the camera. My wife is a photographer. This is coming from her. It's the light.

I also just took some pictures of things around the house that are on a white background. like pictures on our wall. I took some with flash, and some without. Now it appears that this red spot for me only shows up if the picture is completely white and I don't use the flash. If anything else is in the picture, it's gone - with or without the flash. Seems like a non-issue to me.
Read up on how to do a white balance for your camera.
As you go further out from the optical center of the camera, the angle which the light makes with the normal to the detector increases. This in turn means that, toward the edges, there's more chance that a light ray will travel through more than one of the colour filters, resulting in a color shift at the edges.
Here, it looks as though the camera white-balance has fixed a colour shift around the edges, at the expense of the center shifted to pink.
Phrases to google if you're interested: "pixel crosstalk", "bayer filter", CFA.
All smaller imagers are prone to this; they're simply too short for the optics to be close to telecentric (i.e. all rays hit detector at 90°). In a scene where there's a better range of colour and lighting, you likely wouldn't notice any problem at all. If you do, then cell-phone cameras aren't for you

I can't see the banding all the time but when I do it's very annoying. I'm going to try and post some pics today. Is it normal or can I get it fixed?
No one at all has this problem or has heard of it?
what do you mean by banding? describe it properly
in my case specifically i can see faint gray horizontal lines going across the lcd on my phone about every quarter inch. it is especially noticeable on a white screen. i emailed the ebay seller and they stated that it was normal and i would not be able to return or exchange the phone since it was sold as new. i emailed LG about it and they said it would cost anywhere from $40-$100 if it was actually a flaw. like i said in the first post, i'm going to try and get some pictures up soon (hopefully in a couple hours after i get some sleep) to graphically show what i'm talking about.
DarkKnight62, if it helps in any way: I have observed this on my screen too. The faint gray lines made me believe text lines were burned in the LCD screen, but that would have been pretty much impossible, since I don't read that much on my phone. I can only see this effect when I use the screen as a flashlight - white background and 100% luminosity and it doesn't bother me at all.

even I read a lot on my phone but I keep the brightness lower than the lowest default. so I dont have this problem.
I think, It's due to surface dithering. See our phone is not 16m colors its 256k so the colors that are missing are to calculated and displayed and that's why the horizontal band if the we set no surface dithering (custom roms mik) the banding just vanishes but the quality of display is reduced. All the linear gradient colors are no more gradient.

I do have this gray lines horizontally and vertically if you see the phone far and carefully only in white background... when its near, the lines just dissapears to my eyes, (like if they get used to the display)
"gray horizontal lines going across the lcd on my phone about every quarter inch"
I don't think he is talking abouth the lines between pixels.
can you post a picture so we can understand what are you talking about?
@DarkKnight62 I had a same problem. If you are using francos kernel (and/or roms that have it integrated) it's more visible - very noticeable on wallpapers with smooth gradients. Try switching to stock or mik_os CM7 mod 6.5.4 stable (which is great)...
@soberspine This is example:

Hello everyone,
I noticed that at night when I have a black background i can see dark spots that make you notice the color is not uniform.
This defect occurs when all these conditions are verified:
- Completely dark room and eyes accustomed to the darkness for a few minutes
- Completely black screen (like the one in the test screen by typing *#0*#)
- Minimum brightness (but can be seen even at maximum brightness).
In practice, you see lots of little dots of different sizes and shapes, always black as the background, but not the rest of the uniform color (as if they were the signs of glue that is below).
During the day with light are virtually invisible, at night using it would not normally notice, but as soon as the screen remains black for a few seconds (for example when loading a video from youtube), here they are appearing and are really annoying.
I got my phone last week, I would still be time to ask to replace it, but I'm afraid it's a problem of all devices and maybe even put the risk of receiving a worse one (with dead pixels, circles on the screen, etc.).
Someone else has ever noticed these spots? If you have not noticed could you do a test under the conditions that I outlined above?
To understand whether it is a problem of all (in which case I would avoid to let me change) or just mine.
I still have 2 days to apply for replacement, thanks!!
P.S: sorry for my bad english
Same on mine, and a lot of them... not really visible that much only with blank black screen... and sincerely when do you use your phone with nothing on the display ?
Im pretty sure those are manufacturing imperfections in the amoled production process and we cant do anything about it, im pretty sure all phones have it to some extent.
Same here... I think that its bet to just get used to it, that what i did anyway..

Yes, I have the same problem too! Just got the white version of this phone. I also noticed that mine looks like there's a small fingerprint smudge underneath the glass. These don't bother me, but what really bugs me is this faint faded line that runs up and down the screen. It looks like burn-in or something. I can't see it unless I'm playing a certain video with gray backgrounds. Should I swap it out or keep it? The one I have now has no dead pixels, but I'm afraid the new one would...
Hmmm so we all have this problem, any other witness?
Yeah same thing i was thinking im only one
/problem with all oled screens
same with mine..its a flaw by samsung. unequal distribution of glue to stick the glass and capacitive layer
Same here ...
At first I was a bit worried because I also have an LG Optimus SOL E730 with amoled, and it does not suffer from this problem.
So, the only thing that comes to my mind, is that samsung did a crappy job on this phone.
One more thing: When the screen is black, the LG appears as if it's turned off, the Samsung, on the other hand, is a little lit.

Please refer to the picture below. Do you spot any abnormalities with my SAMOLED+ display? The yellow tint is gone after flashing to 2.3.5, but the area in the lower left is still showing a lighter tone--like a right triangle; so does a small area on the upper left. Also, the brightness (as I've noticed in other S2's) is not evenly distributed across the screen. These problems are hardly visible in normal use, but it becomes visible in grey backgrounds, and notifications area, and lowest brightness in web browser. Please let me know, thanks.

so, what do you all think? Please let me know thank you.
Mine looks exactly like that: triangle in bottom left, splotch in top right, and whole left seems a little dimmer than the rest. I haven't installed any updates & bought mine in South Africa; where did you get yours? I was honestly under the impression that AMOLED was the technology to go for, but now I'm not so sure anymore.
At first I was going to ignore the lighting defects and the pink tint in the center of camera images as there aren't that severe, but now I've found my phone's earpiece probably has a problem too. It makes a crackly noise during calls that sounds like something's loose in the speaker, so I reckon it's time to send this one back...
Update: I got mine replaced today due to the speaker problem, and the new one has neither the triangle nor the splotch. It is still darker down the left side of the screen though, maybe even a bit more so than on the old one...
I had exactly the same issues (well, not exactly as mine were worse). I had to replace it twice. Now I have one without this issues, no yellowish border and little to no banding.
The guys at the service told me that if there is any problem now, I can get a new phone right away, but considering how many people have display problems, I would rather repair this one. It's display is suspiciously perfect...

So I am seeing some color issues with my SII
Not sure if it's just the way it is (because I am coming from the LG G2x which had the most amazing display you can ever imagine), or is it just my phone.
The funny thing is that even though I am attaching a screnshot, obviously YOU will not be able to see the issue (since of course, the pic itself is fine, and it is the display that makes it wavey...)
I am not even sure I am explaining myself the right way.
Wavy colorts, uneaven, almost cartoonish-like, smeary.
It is most apparent with darker shades
(U can't see it here)

Samsung's Super AMOLED Plus displays exaggerate colors and shades, and that is it's key feature. Not sure about your phone, but if you think something's wrong with your phone, go check with your service provider.

Thank you!!!
Found some info here, i wonder if mine is one of these....

I hope more members will have something to say, perhaps they have experienced this as well.
I was also thinking whether this can (hopefully) be a kernel issue or color calibration issue? I know that some kernels has effect on the colors, but I am out of my field here and completely wrong
The weird thing is that light colors are perfect. When GRAY or BLACK, it just looks bad.

I've got something similar to that.
It's not noticeable in a well lit environment but if I'm in a dark room and have a black screen on my sgs2, some blotches seem darker than the rest of the screen.
I wouldn't be too bothered about this if it was just one or two but there's one large one and a bunch of smaller ones scattered around the screen.
Thanks!
I wish I could upload a photo to show it, but (funny enough), my only camera is my phone's camera (a single student - what r u gonna do?!)
This is especially noticeable when I take a picture or when I use the Music app (pictured above), where there is huge smears of color going from the dark to the lighter.
I hate to even imagine it, but I think I will have to depart from my SII if this is something that isn't fixable. If no one else experience this, I will get a new SII
(i don't know anyone that has the SII so I have no one to compare it to)
Managed to take some pics
Hope U can see it:
Look at the bottom discoloration:
All menus with shades of grey and black present this issue (kernel problem maybe?)
NOTICE POWER WIDGET!!!!
Not sure if i'm not searching hard enough for old topics related to camera of sgs2.
i noticed that there are vertical lines/waves or whatever you call it when taking pictures. it appears on certain light conditions and surfaces. light brown/flesh and whites.
is this normal? if not, is it hardware or software issue?

anyone?
cant c the lines but may b lens is dirty or some thing on the inner glass
not me........... try wipe or flashing stock ROM and see again
Ya now I c it atifsh is right.an u can flash the camera firmware.
Sent from my GT-I9100 using xda premium
i think the lines are caused when you're under florescent/CFL bulb regardless if daylight or warm light.
this does not occur under incandescent bulbs
i have the same issue...
I took the phone apart, cleaned the len and the cover and still get the same result. The lines wont go away.
Someone mentioned you can flash the camera's firmware?
I've tried different firmwares aswell... CM9, MIUI, Hydrog3nics... all of them resulting with the same issue... I should try on a stock rom...
I would apreciate it if someone with a stock rom can take a picture of a white piece of paper with flash off under fluorescent light and please post the result...
Thanks again
The one i posted is already stock rom, stock firmware camera (dxlp7) under fluorescent light (office lighting).
I tried to reproduce it using ordinary fluorescent lamp and dont have this.
i think, might be wrong here, the problem is the interference (electrical or something) that causes this waves. i tried taking picture vertical still under the same lighting and don't have this anymore.
i just want to raise the issue again. i noticed that this is also present in gnote. yeah this is sgs2 section but i havent found any fix yet.
images here are from s2.
what's surprising is that lumia 900 and 800 have this issue. common denominator: amoled.
Have it Note
Sorry, i know im on the wrong forum (or i have the wrong phone)...
I have been searching for a fix on this issue. It is also present on my galaxy Note. Those lines are irritating, most of the time when im indoor and with so many fluorescent lights around the camera lines appear.
Hope samsung get to notice it and give us solutions.
here's another
