Color Banding - Galaxy S II Q&A, Help & Troubleshooting

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.

[Q] Disabling screen sharpening

Hi,
I'm kind new to SGS2, coming from a Milestone background with mostly CM roms (kabaldan is an amazing XDA member!)... it's a very different world indeed... =]
Right now, I got my SGS2 for 2 days, already rooted with CF and just returned to stock KE4 kernel to compare/test battery life and other stuff before choosing a kernel to stick... I'm liking the device a lot, it is powerful and compact, maybe it could replace my standalone music player too (O2)... but one thing really catch my eye in the device's screen and it is hard to ignore, the screen sharpening that happens in the, otherwise beautiful, samoled+ screen... is there any way to disable this "feature". I know many of you may like it, so I'm all for choices, but specially working with feature films and images/display background, this kind of effect (sharpen) really bothers me.
So, if anyone has any info about changing/disabling this effect, I would really appreciate.
Tks.

[Q] i9100G dISPLAY DIFFERENCE !

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.

Video quality improvement with custom ROM

Hi,
I have using Prime for more than a year now with stock ROM (rooted). The colors especially white looks faded/washed out. Will there be any change in the color/display with custom ROM? or is this dependent on the screen? I am planning to install a custom ROM
does the colour look fade out in other apps?
for most things i would want to say no, cause that would mean your display is dying out... but the asus tab is a bit weird....
i find it when the battery is low it starts fading out like you said
so you might have some like if you install a new rom on it

[Q] Whites not white

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 .........

There exists such a forum HERE.
So is it hardware or software? Any ideas?
You can flash http://forum.xda-developers.com/showthread.php?t=2190293 and use the white balance from the Z / ZL phones, shows up then under Display

Yep, works fine ! I have a 16GB Wifi, on 370 rooted, UB. Same setting as I have on my Xperia Z for white balance.

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!)

What theme is this?

Anyone able to tell what theme this is?

That’s High contrast theme II. It’s free.

The only ones I see are "High Contrast Theme" and "High Contrast Theme: Sky Black."
Sky Black is close but it doesn't seem to be the same one. I realize if it costs money you probably can't share the link, but could I see a screenshot of it in the Galaxy Apps theme store?
Edit - it is Sky Black after all.

I think it might actually be Black Onix by Gabriel Santana, as I have it on mine and the colours used on the settings screen match the purple/blue/turquoise in that picture from android central (and the theme's wallpaper seems to be the same as seen in Michael Fisher's video).
I do like the Sky Black too though.
Black Onix is it! I thought Sky Black looked ever so slightly off, and I use a different wallpaper anyways.
That said, I prefer the Messaging look with Sky Black so I may stick with it for now.
Thanks!
