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 have a problem with their Atrix flashing a yellowish flash rather than a bright white when taking a picture or using it as a flashlight? I was wondering if it was just my phone that had a bad LED flash or if it's all Atrix..
Mine is yellow also.

mine is yellow but i'm more concerned about the flickering when on a flashlight app. warranty time if yours does the same.
I think the yellowish tint is intentional to mute the buttons. My Fascinate buttons were bright white and really drew attention. I like the muted off white color.
edit: I mis-read the thread and posted about the led backlit buttons, not the LED flash... my bad. However, there are threads about the yellowish buttons!
Yeah i prefer the yellow, i had the bright white on my nexus one and it always washed pictures out.
Yes my flash leds are yellow as well I think this is standard.
I honestly like more the yellow tint than the insane white of other phones. Gives a more natural color to the shots.
Hmmm good to know this seems to be standard. I took some test pics and looked very odd to me. Maybe it was a combo of the off screen colors and yellow flash..
My Atrix is yellow but my girlfriend's atrix is white... I will show pictures later if there is any interest...
It is a common belief that SAMOLED has no backlight, which is true. However, the screen IS powered and hence there is SOME energy that generates a teeny tiny amount of light.
This can be checked by using the *#0*# and doing the Vibration test where the screen goes totally black.
I'm talking about a VERY VERY faint and very uniform glow from the screen.
Try waving it in front of your face if you don't see it.
Report back.
Hi,
Yes. Even I have noticed this when I am using the cell in night and in a completely dark room. I am not sure about the SGS 1'S screen, but in the S2 I have seen a very faint glow which is present in the backs even when there are other elements colors present on the screen. It's my opinion that there is some amount of backlight that is being used for the black.

Both the i9000 and i9100 have a faint glow when nothing is being shown on the screen
I havent seen any glow just how "teeny tiny" are we talking about here?? If you keep reasonable distance from the screen then it is perfectly black. Watching a video with black bars in a completely dark room the blacks are literally indistinguishable from the bezel.
so far i had 3 galaxy sII devices the last one was the white color
all of them had the same thing ur talking about in complete darkness
Yes both the i9000 and the i9100 I own have this, you can also spot it while just turning on the phone before the boot screen, but I only notice while in a dark room or at night.
The faint glow is there because the pixels do not totally power down when displaying black. The screen is designed this way to give better response rate. No one wants a screen that ghosts isn't it

You only see it on a fully black screen. As soon as there is anything on the screen your eyes compensate for the light and you lose sight of the black. Try it as the OP suggested and you'll see it.

Okay so we are talking fully black screen.
So while watching videos, playing games or having a black wallpaper(with obvious widgets or icons on top) the eyes would perceive it as pure black as I have experienced.
So for all practical purposes the contrast is infinite. OP you shouldnt worry about some glow on a fully black screen. I can tell you for sure that even in totally dark room lets say you are in the ICS app drawer you will not be able to see any glow between the icons, it would seem like the icons are flying in the air. The magic of SAMOLED.
Yes, there is a faint glow. But its only noticeable when you're in a completely dark room and your screen is showing only black.
However that does not in any way mean that SAMOLED+ doesn't have perfect blacks.
The glow is there only because the pixels aren't actually powered off (at least that's what I think)
The contrast ratio is still infinity.
The OP made this thread to prove a point, just checked and YES there is a faint glow in complete darkness.
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 )

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.
Hi,
When I am using the flash indoor and it is dark , my pictures have a blue tint. I can see it already when the flash starts, just before taking the picture, that my screen has a blue tint.
I have noticed that , if I don't use the flash indoor and it is dark, I still have a very very little bluish tint but negligible.
When I take a picture indoor , but it is bright, , and the flash is set to on ,my screen doesn't become bluish and I have a "normal" picture"
Any idea what to do?
Daniel
Hi,
could it be that the blue tint comes from the LED being kind of blue? Not to sound sarcastic, but I think this could be the answer to your problem. Because when you look at the LED when switched on, you will realize that it is not pure white, but just a little bit on the blue side, that's at least my impression...
Check the white balance option in the camera settings, it's probably set to daylight or something, change it to auto or flash. Obviously the latter if you are using flash at that moment in time.

I had a thought that if it wasn't the white balance then it might be whatever colour setting you have the phone's screen set to. Try changing the display mode to something else then view the photo's again.

Settings -> Display -> Screen Mode
Try changing it from whatever it's currently on to something else, then check the photos again, repeat this with all the screen options. There could be a screen calibration problem with your phone on one of those settings.

Thanks but I have tried this already before and there is no difference between the 4 modes and the blue tint.
I think that my S3 has a little blue tint because I have compared it with a friend and there is a difference when viewing an application with a white background.

Sounds like a faulty screen then, take it back and ask for a replacement.
And you are absolutely 100% sure your finger/thumb/whatever is absolutely no where near the flash? As that is by far the best explanation for this and common reason for this. Just check anyone on Facebook and look at their mobile uploads... You'll see lots of photos with blue tints and it's because people take photos with their fingers to close too the flash reflecting light back at the lens.

I find that is the issue for me also, I've noticed it happening when in a room with a TV on for example.
The GS3 has a hard time picking the right WB, it would be nice to have a WB setting for the cool White LED the flash uses.
Maybe a simple piece of scotch tape placed over the flash (with a light yellowish tint) will counteract with the blue tint.
I tried this with some painters maskingtape, the yellow paperbased tape. The pics aren't so blue anymore.
The only problem is finding the right yellow tint.
Maskingtape is a tad too thick and it interferes with the range of the flash.
ahh yes, my friend vs my sgs3, we did a flash light comparison. my i9300 version infact has a slight blue tint to it compared to his neutral tint (att version). I can confirm the blue tint is in fact a real thing

rosco swatchbook on amazon. just ordered the small one; i'll experiment and pick what works best on a neutral white sheet of paper. i'll cut it out and sandwich it between my phone and it's case right over the led.
ridiculous oversight on samsung's part not to white balance the flash's led. pisses me off that i have to resort to this on a flagship phone.

I am on yureka . i can easily confirm pic is bluish because flashlight is bluish. How to solve this. Some other camera app has two type of flash one tourch and other is default flash. Tourch light gives good pictures. How to make a tourch flash by default.
The bluish tint could possibly be how you perceive the image on the screen of the phone.
For example, I just took a photo on my i9300 and can clearly see that it is in the blue spectrum when comparing the photo on the i9300 against real life.
I sent the photo to my HTC M9 and on that screen it looks more like the original real life with no bluish tint.
Therefore I know the camera is good and taking colours correctly but my screen on my i9300 is what seems to be giving it the blue hue.
