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!

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.

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

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!
Do you have such stains? I hear this is normal among AMOLEDs.
welcome to mass produced (aka economically viable) OLEDs...
Some patterning or colour patching is inevitable even from new. Blue or Grey backgrounds tend to show patches up more. Very low brightness shows a greenish cast on the left of the screen too.
It took more than a decade before LCDs could be produced in volume with a very low dead pixel yield.
We have a dozen GS2s at work and they all have minor screen issues. From new. They do get worse or even change position over time (many months) as the pixel level elements shift in luminosity.
Also note that if the phone is warm, the effect lessens.

Thank God I don't have dead pixels. At least this patch I got is visible only on dark-gray / medium-light (so-to-say, idk) brown. I'd rather have that than dead pixels .
Actually, if I start Screen Test, the patch is visible on ALL colors. On blue/red/green, it is less visible. On white, it is most visible. Also, when displaying full whites, the color is not homogeneous. Vertical and horizontal lines seem to be present ALL ACROSS the screen. These lines are visible on white, yellow and such colors.
At least I don't have ghosting effect and the whites are actually white, not yellow - as it was on Gingerbread (yeah, software problem, eh?).
So... the patch appeared to have vanished after running the fix (which rapidly ****s four colors) for half an hour, because the screen was a bit warmer... and as it cooled down, the patch has shown its face again. Oh well...
the galaxy note and s2 super amoled screens are prone to burn ins, very common, you need to eliminate risks involved.
Turn off auto brightness, lower the brightness level, shorten the time youre screen stays awake for, and if youre using themes, avid the blue themed ics ones, although they look nice, the blue themes are one of the biggest culprits of the burn in issue and before ya know it youve got a battery image burnt in.
i notice it looks like you have a blue theme or something, my mate had same issue, what can ya do, its a pain and well probably all suffer it, whereas htcs dont have the issue, they just suffer dead pixels a lot, but hey, id soone have slight burn in than dead pixels i guess

F*** !
MIUI uses white & orange. Are those colors dangerous, too?
I mean... what colors should I avoid the most? Besides blue - I get it, it's bad (again, F***).
Anything that turns the RGB elements hard on (!). So high brightness only and white is worst as this is RGB full on, then pure red, pure blue, pure green. Cyan, yellow and magenta are less risky. In theory.
In practice and the real world, just keep the brightness down a little and you'll get years out of it. And save battery - the screen is THE major power consumer...

+1 absolutely right, follow these simple rules and all should be good.
White requires all three elements (RGB), right? Blue = B. Which one should I stick to...? My logics tell me blue, but I hear AMOLED's blue color is so pure because of a compound from algae (rofl) and it wears off more quickly (if any of that makes sense).
Cyan, magenta, yellow... Yeah, I don't have that on AOKP, lol. And neither would I want a yellow theme. Magenta would be nice, though.
RGB... hell, those are the primary colors. How about we use black, with polarised glasses? That'd be a good deal, since I wear glasses, lol.
Seriously, guys, what do YOU do to make sure the screen doesn't get damaged over time? Don't tell me you're using a yellow-black theme. And setting the screen brightness to 50% or more is required outdoors, so...
-----
I just went to a showroom today. Seen the Galaxy Nexus there. It's on, with the brightness set to maximum, 12 hours a day, and it's been like that ever since they put it there - more than 3 months. Seeing anything strange here?
well, as a rule i dont have wallpapers that have bright vibrant colours, i find it annoying and painful on the eyes, and if you have shortcuts on the homescreen it gets to looking messy, so i stick with dark colours, to be honest most of my wallpapers are black or almost black and my brightness is set at around 20%, and i dont struggle to see it outside in sunlight or anything, but this is just my prefernce, im sure everyone has different tastes, i think you should just enjoy your phone and use it how you wish, but try to avoid having it too bright, it should be ok.

I'll stick to the stock AOKP theme (blue, that is); but I will be careful not to raise the brightness above the point of 50%. And even if I do, I guess setting it to the maximum point for a few minutes (when the sunlight is very strong) wouldn't hurt...
Oh and mind archiving your black and dark wallpapers and sending them over to me? Please (I'm always happy to pile up such wallpapers)
Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )
Sent from my GT-I9300 using xda premium
It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
Just picked up an AT&T One M7, and wow, the screen temp is incredibly warm compared to my G2 and just about everything else I use with an LCD screen. Is there an app/rom/kernel (or any combo) out there that will back my screen away from the warm tint? Thanks!

The warm tint is supposed to be correct and true to real life colors and what you actually see. Why would you want to stress your eyes by making the colors unnatural and harsh? I wish more companies would make their LCD's this way instead of the artificial over driven blinding harsh colors.
I calibrate my Nexus 5 with the SpyderGallery app. You just need a Spyder sensor... It isn't really a calibration in the operating system. But it will show the right colours opening images in the gallery of this app. This helps me when showing photos to my clients.

I wish manufacturers would give consumers the choice. Clearly there's a variance in panel manufacturing and factory calibrations, even from within the same display supplier. To me, warmer, yellow screens looks dingy and dirty, and not what my eyes are used to when reading web pages. So the warmer temperature may actually have the opposite effect on my reading comfort. Nokia has begun offering an in-OS setting on WP devices that helps correct minor variations - and I'd love to see other OEMs follow suit.
One interesting thing that most people aren't talking about is the fact that Samsung's new displays are actually TUV Rheinland certified for significantly less blue light emission (advertised 42% reduction), while still maintaining optimal colors and picture quality.
To me this is a huge selling point. Most people probably don't care, but blue light is shown to cause significant eye strain, and slow the development of melatonin in the brain., destroying your sleep quality. Just curious on everyone's thoughts about this.
Here's some more info if anyone's interested;

https://news.samsung.com/us/samsung...rp-reduction-blue-light-emission-oled-panels/
Samsung discussed it at their event. Reviewers/Youtubers and tech sites rarely comment on blue light emission. You'll come across more articles on how to kill Bixby! The Honor 8X was certified too, but few speak about it.

Blue-light filters usually make things yellow, but I checked the s10/s10+ in a shop and the display is PERFECT, the white levels are incredibly pure and it looks cleaner than my XZ1's IPS which I thought would have unbeatable whites when compared to oleds, that's no longer the case.
I always hated OLED but Samsung found a way to reduce its drawbacks while creating a super accurate panel, if you want to buy one last AMOLED device while waiting for Micro-led to be a thing in mobile, this looks like a very wise choice.

They're still trying to shrink it for the average TV size, I hope it will come soon.
Did some more research on the Honor 8x, it appears they are advertising blue light reduction with their "eye comfort mode" which tweaks the colors you are seeing. While on the other hand, Samsung is pointing out the 42% reduction from previous OLED's still maintains the same colors you're seeing. So based off that, the S10 is capable of reducing exposure without software tweaks.
It also appears that out of the box, the S10 is defaulted to the "Natural" color setting, and provides a "Vibrant" setting, which does increase color saturation. I wonder if the higher color setting changes your exposure by much...

Did some more research on the Honor 8x, it appears they are advertising blue light reduction with their "eye comfort mode" which tweaks the colors you are seeing. While on the other hand, Samsung is pointing out the 42% reduction from previous OLED's still maintains the same colors you're seeing. So based off that, the S10 is capable of reducing exposure without software tweaks.

Then the Honor 8x's solution is nothing more than a software re calibration tweak, I'm glad the S10 comes with a hardware solution that doesn't impact viewing experience.
But yeah using Vivid mode will increase your exposure to blue light depending on the displayed colors, I wouldn't worry that much, it is in no way as dangerous as the exposure to TVs, Desktop monitors or even daylight.
Can someone link to a bluelight study that shows its harmful. I lost my ebsco access when I left college. I always thought this was an overreaction. I've been staring at cool temp computer screens since the 90s, and my recent eye exam says my eyes are still perfect.
I've found the press release, but no peer reviewed papers.

Glad to know I'm not the only one. I even wear reading glasses with blue light filter due to my extreme light sensitivity, so yes, totally big deal for me too
Pwm is for losers. Now Sony is also on the oled bandwagon.
