I've seen a lot of youtube videos of the galaxy s II and from what I can tell, the screen is still oversaturated like the original galaxy s, with the same blue tint on white backgrounds. Any chance this would be adjusted, or even have a user-adjustable option, by release? I'm guessing a majority of people outside of forums don't care and prefer the gaudy colors, like how they crank up the color on new TVs and everyone's face looks red, because buyers prefer it. But an option would be much needed for those not so inclined to the heavy colors. Another thing I would want is a lower brightness setting. LCDs get washed out but AMOLEDs can handle lower settings and still have good contrast. With that, the ability to adjust the minimum and maximum threshold for the auto-brightness instead of one predefined setting, as well.
I doubt Samsung (or any other manufacturer) would let you modify that much in the settings. The phone is not a monitor, however I certainly see the possibilty of changing those options (or at least some) once some kind souls will start messing with the firmwares and kernels.
*cough* supercurio voodoo color *cough*
If it involves *cough* hacking *cough* I think I will have to pass. And yes, there are less industrious people around here as well.
i am pretty sure that the sgs 2 will have the same same over saturated colours and the tint(looking at review videos).i am not a fan of amoled i do like its blacks but the over saturation does my headache i prefer ips to amoled any day. if it was not their Soc's i'd never have bought sgs.

Or the Nexus S general forum. Fingers crossed.
A challenging task for the devs here ...........
I only see a blue tint when I tilt the angle of the screen. It doesn't take much to see it and becomes more extreme the more it's tilted. Looking straight on is fine. I didn't expect there to be perfect viewing angles but tilting just a little the blue tint is really prominent. Easily viewed on a pure white screen.
Great phone, though I want to use the device to watch videos and two things bother me: the blue tint when not viewed straight on and the over saturated colours. The colour green is very oversaturated much to the point where I think there's green in the videos showing up that shouldn't be there! I know you can adjust the colour tones, that include warm, cold and natural. If the image looks too yellow/green then the cold setting looks a bit more natural on some videos. I would have preferred a proper configuration for adjusting the complete colour balance.
The screen is wonderful but is let down by these two things. If it's something that can't be helped then that's the way it is, but it would be great to have more control over the colour settings and if the blue tint is really a limitation of the type of screen/glass, or the first batch of phones have an inherent fault with the screen?
On thing that is also off is the gamma curve!
greys become dark too fast, shadow details are crushed, even though the screen has the potential not to do this. On the contrary, with such black levels, the panel should be able to show more shadow details.
I suspect this is a battery saving choice, rather than a screen limitation. I'd rather have an accurate gamma though.
Google will need to allow custom color profiles in Android soon!
My Galaxy S has much more natural colors than the S2 that I just bought. I can't stand the disney colors! Hope some developer will be able to fix that soon!
Is it just me?
How come you guys say that the SGS2 has bluish tint? While when I compare it to my SGS(speedmod) and my friends SGS(voodoo) my SGS2 has a yellowish tint to it? I'm a bit confused. Anyway I've bought it and my only complaint is the sound. Voodoo control plus please!
There is some degree of control (not much though) over the saturation in Settings > Display > Background effect.

The easiest way to see this is to view a white page/screen. Look straight on and then begin tilting the phone in any direction. The blue tint becomes noticeable and more extreme the more you tilt it. I wouldn't have a problem if it was only noticeable at extreme angles, but I do see it if the viewing angle isn't straight on. For phone use this is fine, not so bothered. Not so good when watching media.
Regarding the tint,
Also when i purchased the phone in may the gray was going into pink!
On later updates colors seem better! aswell i rember i posted a request in chainfires 3d drivers tread were i ask the guy kindly to add support for custom rgb mode nightmode tones...
So from his application if u play with nightmode function you can tilt your color as u like!

There is actually a post/study about this :
http://forum.xda-developers.com/showthread.php?t=1124669
Does anyone know if there is a way to adjust the display's color saturation and color balance? While the screen is eye popping to look at, the colors are not accurate. They are distinctly warm and oversaturated. This is great for looking at icons, but not so great for photographs. I know the international Galaxy S II has something called "background effect" where this can be set to 3 presets with varying saturation levels. But this option is missing on the AT&T SGS2. I found an app called Screen Adjuster in the market, but that only lets you increase saturation or change color balance by increasing the intensity of the Red, Green, or Blue values. There's no way to turn them down.
So has anyone figured out a way to adjust this? Thanks.
bump. also hoping to find a solution for this but not having any luck yet
+1 on this.. I am a professional photographer and I used to use my I4 to present my portfolio. As of today I can't do that, or I have to do re-do my portfolio specifically for the SGS2's display. Which I really don't wanna do.
"app called Screen Adjuster in the market"
Thanks for this! At least with that the color temp is somewhat fixable, but overall colors are still terrible. As long as Samsung insists on locking these devices into torch mode we're just screwed. It's a shame that this didn't ship with several selectable profiles like the regular version (although I never seen it so dunno how good that implementation is.)
Working on hardware calibrated monitors all day and then looking at this phone is a bit jarring.

I totally agree! My wife's iphone 4 looks way better with photographs. To me, photos on this phone look cartoonish.

This would be great. Caartoonish is exactly what it it. However, we need to keep in mind these displays are far from professional grade. I won't argue that some software could help bring a small level of 'professionalism', however.
I just read around the web that the international version of this phone has Settings, Display, Background Effects to calibrate?
------------------------------
Well I checked out Screen Adjuster and it has the ability to change R,G,B values along with the brightness and Contrast ... so that's enough to for me to use me Eye-One Pro to calibrate the screen. I just need to put grayscale and R,G,B targets to the phone.
This should work just fine
can you post your settings when you calibrate it?
I also found this
Calibration Hack for Nexus One
Which I am now using. Since it has the grayscale bar built in. But this one requires Root access as you need to put the apk in to the /system/app.

Great find! Do you know if CM7 is a requirement for this? This may be the best option for color correcting the display.
I just realized that with Screen Adjuster, you can change the color balance by adjusting the relative values of RGB, then turn the Brightness down to compensate for the elevated brightness levels. Without turning down the Brightness, the black pixels are no longer black. So it's a pretty decent solution.
Just got Screen Adjuster, are there any recommendations for "optimal settings?"

I'll look into this - I'm surprised you find yours too warm, I think my phone is a little on the cool side - without a doubt bluer than my Infuse.
If it's supported by the I9100, I can probably find the relevant kernel interface.

Problem is... just like calibrating a TV/Monitor is that it doesn't have High Bias and Low Bias R,G,B. High Bias changes the whites and Low bias changes the black.
Also, unless you plan on using your display at a constant brightness level, you will get color shift in the lower end of the spectrum
For what I have done is create an 18% gray jpg and a 82% gray as well as a 50% gray.
ON MY display the whites is on the warm side... but there is nothing one can do about it, because the apps just don't have those value to change
ON MY display the blacks are also very warm...
I WAS able to use my i1Pro (spectrophotometer, unlike the cheap colormeter) to get it pretty damn close to 6500k in the Black and Mid-tone.... again nothing one can do in the whites.
I am 90% happy with the results (I'm anal, but I can't do anything with the whites!)
My settings might get you close to 6500k (most likely not.. because ever display is different, and from what I see here some are too warm/cold..etc).. My settings are to use with Calibration from the Nexus One thread, and they are set up to have a warm mid-tone
Red: 627, Green: 623, Blue: 665
Mind you that I also am using CM's 7.1 with the brightness custom level set to my likings...
But it's night and day difference (if you are looking for realistic color representation). A lot of untrained eyes like the eye popping colors, while a calibrated display is much more subdued.

I keep getting a force close after I install the apk. What version did you use? The app installs fine and will open but when I try to adjust RGB, I get the forced close. Thank you!
My prime has always had this issue since I got it and has seemed to stick thru resets and new firmware. It looks to be a gamma issue washing out light colors. Any idea what I could do or need replacing?
AOKP has some gamma options, don't know if work though.
Sent from my tf9001 with XDA XD.
up your device to performance mode, and max brightness. see if it looks better. ive noticed the auto settings from asus dont just change brightness and processor voltage. it seems to change the OLED power. on power saver its obvious on mine.
all icons looks muted, hard to read. turn to performance and its sharp.
dunno
You know what? Changing to performance actually changed the gamma a bit and its much better looking now. That's crazy, I had it on balanced. I'll test it out some more and see if its good to go and see if I can get some shots of the difference.

Hi Guys, got the v10 (h969a) since a week.
After years with amoled, i expeted to find a very cold screen color temperature with the ips.
Well, it' not as yellowish as my note4/s6.edge was, but it's not so white as the g4 is.
I think it's not related to my model, if you search for comparison v10 vs g4 on youtube you see the differenc..
So, is there an effective way to make my screen whiter??
I've found tons of app that apply an overlay, but it's not a good solution.
I need something more effective.
Thanks indeed for your help guys.

Hola!
OK, at some point I will finally update the calib.cfg file again. But for now here are the settings I am using with a KCAL enabled kernel to remove ghosting from my screen as well as drasically improve contrast and colors.
I use Kernel Adiutor:
-------------------------
Under 'screen' section >
Screen Color (This kills the ghosting a lot of users are experiencing as well as removes the blue tinge the screen has):
Red = 250
Green = 250
Blue = 235
Minimum RGB value = 35
Saturation Intensity = 27
Screen Hue = 1520
Screen Value = 112
Screen Contrast = 132
---------------------
I have been running it for awhile and it looks fantastic and I have not had anymore ghosting. It also makes the screen look similar to my Note Edge when I first got it. Contrast is improved a LOT. Colors are better. They are not over saturated. Very close to natural. Whites are white and not blue (at least on my display) etc.
Please let me know your results.
-helf
Works good here!
any way to change these values without root as I updated to the new tmobile update and atm there is no root method

I don't think so, no. These require a kernel with KCAL integrated. You can kinda adjust the screen values without root by going into settings > general > accessibility > vision > screen color adjustment > manual
But that's about the best you can do beyond nonroot screen filter overlay like cflumens supports etc
Thanks Helf. with this tweak, the display looks great!
by ghosting you mean image retention right? if that is the case, well this is awesome! Thanks
A little bit over 15 hrs and no ghosting. My only beef is how the blues look but it's a good configuration overall, easy on the eyes.

How do the blues look? I need to put the phone with a color calibrator and check it. Mine look pretty close to natural when I eye ball it. I'll keep working on it

You're doing a great service for us all. Blue's and greens come off slightly dull like they could use a little saturation but if it's at the cost of prevent the ghosting effect i understand.

hm. The colors in general are probably a little duller. The vibrancy and contrast and all is usually cranked up on phones Samsung is especially awful about it. People like the 'pop' though. I just compared several shades of blue and greens with the screen at max brightness using the camera app, the colors are almost dead on to my eyes. Granted i have to manually drop the ISO a couple notches because the phone wants to automatically crank it too high (like true-to-life brightness/colors around my work desk it wants to use an ISO of 600 and ISO 200 was real world accurate. heh).

You have spectrophotometer? I would love to see some values to use, but wouldn't it be different between devices? No panel is exactly the same, or?
I seem to remember that being reiterated quite a lot on various display discussions I've followed in the past.

Just tried it as well on H918 running WETA with stock kernel and it installed and activated properly but nothing changed. Tried a few different configs and reboots just to see but nothing. Thanks for the share though. It'd be just what I'm looking for if can get to work
Is there any chance applying these changes would cause auto brightness to stop working? Possibly it's coincidence, but I changed my screen settings to exactly how it was in the OP, and since then I've noticed auto brightness no longer works on my phone? I don't see how making these changes would cause that but I figured I'd ask here to be sure, or to see if anyone else has the same problem.
