My Brother just got his Galaxy S2 and when he started Angry Birds I saw the color banding there.
Its not an effect of the AMOLED, its in the software (else you wouldn't see it on the screenshots).
Here are comparison screenshots:
HTC Desire (2.3.3) (click for big version)
SGS2 KE2 (click for big version)
Can this be fixed somehow? Maybe with KE7 firmware?
Or is this a problem solely from Angry Birds?
hmmm
Ok so I ripped a background overlay from angry birds (the sun ray casting)
Can you run the attached and press switch button see if that is the effect of which you speak?
Edit: I also now think that it could be something to do with how the GPU uses ETC compressed bitmaps

16 bit option shows more severe banding. However the 24 bit colour also shows some light banding effect.
Strange thing is, when I open this page on my phone, the |HTC screenshot shows no banding at all... which seems to indicate an issue with how the GPU/ Driver handles the image in-app which causes the banding.
maybe this could work?

I don't have any colour banding issues really. Maybe only very few in blue mid-tones and very dark green. But not noticeable.
Usually is set to low colour mode by the developer/app. So 99% likely that it's not a fault.
What is the source of your informations?
Thank you btw!

me? my eyes? my devices, the fact that I set my apps to 888 or on some devices they default to 565? Not sure what you mean...
this colour bandings not on all sgs2's, im on my 3rd.... 1st 2 were fine n had no colour banding at all, but im on my 3rd now and this 1s awful, massively noticable on the nexus live wallpaper, the grass 1.... doesnt really matter what the colours are, this 1 has a really dull screen too...... gutted
Colour Banding
Well, my SGS2 was sweet until i flasha custom rom , now even with the same stock Orange UK rom the colour is fakked up!1111 it now feels like a cheap chinese copy of the SGS2.
Even at boot the Orange animation has 50% colour that it used to have.....
I have to say I never really noticed this (or at least let it bother me). I just fired up angry birds and can see what you mean. Annoyingly, I only just flashed KI3 to a mates SG2, else I could have looked at his to see if it is any different.

I am having this issue with my SGS2, but I don't believe it's a hardware problem. I took screenshot on a Moto device, and transferred the PNG image to SGS2. The gradient color is shown without any color-banding effect.
So I was reading some comments comparing the SGS II and Galaxy Nexus on a website and I read this comment.

basically everthing the SGS2 got dinged for was Gingerbread related, other than the screen. The screen isnt that big of a deal, they are both top of the line screens and its already been proven you can take the SGS2's screen and make it 720p.
What does this person mean? How can it be changed if the screen is 800x480?
Also, does anyone know how to get the saturation options from the international SGS II and Sprint SGS II to the AT&T SGS II? All the other saturation adjusting apps don't work right.

where did you read/find out that was possible? i strongly believe you cannot change the resolution, its hardware, not software. You can change the density, which will give you the illusion that the res is higher, but its not. and also, when you change the density, a lot of things on the phone won't be scaled correctly. if you can, please provide a link to find this info...

It has? Show us the proof then.
Note: Good luck finding this proof, as it's impossible to do this. Changing to 720 would require changing out the entire AMOLED panel. Also, remember the GNex uses a PenTile screen, so its subpixel density is about the same as ours.
Well because it was a comment on a article, I didn't feel it was necessary to include the link. I wanted to see if anyone heard of this as I thought that since it's a hardware issue, it can't be changed.
Do any of you have any idea about the saturation option I was talking about? Can that option be proted to the AT&T SGSII?

Already in S8 and I think Unnammed, or any Hellraised ROM. It's one line of smali in settings.apk

Thanks. I couldn't find anything about the Hellraised ROM you mentioned in regards to the saturation issue. Can you help me with what I need to do? I'm running CM 7.1 so I don't know if that causes any issues.

Guys If you see lower on the comments he sais there is an app for it!! I want to know more about this!!

Found an app on the market. It's called: LCD Resolution (Root)
made by: wemobs Labs
You can't use 'software' to put more pixels into 'hardware'.
Technically speaking Lcd Resolution lowers the screen quality. Say it takes 100 pixels to display one letter of a word. Lcd resolution changes the display so that same letter is smaller and now made up of only 80 pixels. Not as smooth edges.
I love the app. I have it running right now. Seems 192 is ideal for me. Makes my screen feel like it's as large as it really is. More screen, not just bigger icons.

All that does is change icon and text sizes by fooling apps into thinking your screen is higher or lower density than it really is.
Hi,
My sister has a White Samsung Galaxy SII (Me I have a black one). But my phone is brighter than hers. We are running the same ROM and kernel (CriskeloRom V34 and Syah 2.4.2) and the phone is set to auto brightess.
Any idea ?

Only if you have the same phone, it doesn't mean it's 100% the same. Every component is different, and so the ambient light sensor is also a little bit different and decides at your sisters phone to illuminate her display not as much as yours. maybe there are also differences regarding reflection or such things. but i think it will be caused by tolerances in manufacturing...
Thanks dude

Hi people, this is my second Galaxy SII, but this time i got the "G" model. i am well aware of the difference between the chipset difference and the slow cpu blabla.. but what really shocekd me was that even the displays are not the same ! i original galaxy 2 has a deeper and richer colors and i can change them from standered to dynamic...
same option in G version, but when i change the display modes, there is no effect of the image (the one they show on top for comparison) plus, i have version 2.3.6 By ODIN, where my original is still running 2.3.5 .
**** IF SOME ONE CAN CONFIRM ON THEIR "G" MODEL THAT THEIR DISPLAY MODE WORKS OR HAS AN EFFECT FROM SLANDERED >DYNAMIC ---- AND BY THAT WHAT VERSION ARE THEY USING, I AM HOPING ITS DUE TO MY PERSONAL UPDATE THAT IS CAUSING THIS DIFFERENCE OR IS IT JUST THAT SAMSUNG fU**ED ME OVER SINCE IM A ASIAN !
I checked mine, the changing modes make no difference in colors AT ALL. Even on max brightness. Let me check it on I9100.
Also, I disagree about the screen quality differences. The black levels in my I9100G are awesome, I cannot differentiate between black body of the phone and the black color on screen. Also, comparing it with I9100, the whites are also better, the whites on I9100 are more of yellow shade, whereas on I9100G are more on the whiter side. And the black levels are same.

Exactly ! Your black Color is so black just like the body of the phone ! That is the exact case with my i9100 ! I agree with you 100% . But on my G version is not the same case which is the reason im am posting this question ! As i mentioned the colors in my G model seem Dull and less intense and the black seems as if it is being"lit" as a black color compared to the true black in the i9100. Please Tell me what is you version of firm ware on ur G. I have 2.3.6 on it.
Hope fully i hope its just some Bug thats is reducing the colors of my G models
I am on 2.3.6 stock with no rooting. Earlier on 2.3.4 stock there was no color issues.

Hmmm... I got 2.3.6 out of the box... The problem's very well there... No change in colours from Dynamic to Movie... Same dull display
One update released for I9100G today in India. Let me update and check if this issue is fixed. In Malaysia, this menu itself is not there.
Hi i have just got this device and so far love it i just have a question if i look at a blank browser window i can see that white is not pure it has a sort of yellowish tint and if i compare to my ipad the difference is clear on the ipad the white is totaly white. Any one noticed this and how are your whites.
This is already widely known and discussed in various threads.

Have just looked at every thread in questions and cant find anything usefull about this issue i would like to know if i should exchange my device and insist on one with proper whites if they exist or if everyone has this problem and i will just get another one with the same issue
I notice this and me too was to compare this with my wife ipad2 notice specially the browser was yellowish but if the brightness is high it turn white. I had the same with my Galaxy S2 but in the settings you can change the screen scenario (CM10.1). For the browser I use UC Browser, you can set the brightness for the browser a bit higher to make the white more white.

Just downloaded and used screen adjuster from play store and set blue to 11 and yellow tint is gone with that setting whites are nearly pure white so i will keep device as im sure it will be sorted in a rom at some point
A few days I also tried Screen Adjuster, but meh! it's not good.
Slows everything down.
Try scrolling in a good (!) browser (i.e. not Chrome) without Screen Adjuster - buttery smooth and fast. Then activate Screen adjuster and see lags all over the place.
I f I wanted that I could remain with my old Acer A700...
Another issue is that Screen Adjuster is not running all the time; when you start an app, you will sometimes see that S.A. kicks in only a bit later.
There are screen calibration apps by Sony built-in in certain smartphones, also the Xperia Z. So there is hope (and we users must insist) that Sony releases such an app for the Tablet Z in the near future...
for that to happen we need a forum that people from Sony will see and read .........

that sounds great did install that on my experia z will give it a go and would appreciate if you could you tell me what settings you use.
Each display is different - so you have to try for yourself.
My display has a yellowish-greenish tint; saturation=7.5 and color=209 works quite well for me.
(Thanks for the tip, by the way!)
