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
Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B
W
Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Not sure I understand you cpu98!
Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.
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.
Not sure where to ask this, so here goes. Picked up a Z Play for my wife and it's great. Then picked up a Z for myself and while it looks and runs great, there seems to be a definite green tint to the screen when viewed off-center. And I don't mean 30-40 degrees off, but as slight as 5-10 degree off center, in any direction and it has a definite green tint, regardless of brightness setting. Previous AMOLED phones for either of us never had issues until extreme angles, and her Z Play is far better, not turning green til about 40-50 degrees, which is what I would expect.
Is this common or an issue? It's only been a few days, so I can go change it if it's a known issue of any kind. I guess I can also go compare it to display phones.
Mine doesn't appear to have this issue, perhaps a slightly noticeable change when 40° off but not at 5/10.

Me neither, nothing remarkable happening when tilting it in either direction.
When the Moto Razr XT910 was new, there were many reports of varying panel quality problems, such as strong green or yellow tints
They did get new phones when they returned them, as it was a quality issue, could be the same thing now.
If I'm not mistaken, those with lots of green had field/cloud faults when viewing a black image in a dark room at full backlight, as they failed to reach zero brightness.
It was described as the pixels leaking electrons to surrounding pixels.
Viewing angles on the Z is worse than my old Moto X 2014 for sure, but it's probably due to the smaller pixels.
Nothing beats the old HTC One M7 though, that thing never faded, but it had an IPS screen.
However, in standard colour mode, it's heavily yellowish to reddish (some would call it warm colour temp)
In dynamic it's closer to white, but with a strong nudge to the blue spectrum.
Can't wait to get the custom colour temperature setting with Android 7.0!
How well do you know your fifty shades of grey? Rate this thread to express how good the Xiaomi Redmi Note 4's display contrast is. A higher rating indicates that black is true black, rather than a very dark gray.
Then, drop a comment if you have anything to add!
Contrast is decent levels.But there is a pinkish tint on my display which looks ugly
Not pinkish but a slight reddish tint but nothing major gets quickly adjusted to ur eyes
It's good, but when you are in really dark environment (like under blanket in the middle of night lol) blacks are gray.

Yep, even TN LCD's will still glow in the dark. It's because LCD displays have a backlight in the back that is always on, then the Liquid Crystals on top of that can let light through or block it. Then a polarizing filter because liquid crystals only orient light in one direction and without that you would only see white light.
And by having 3 differently colored subpixels for each pixel, colored red, green, and blue, the primary colors of light, it's able to show a couple of million of colors.
Because the liquid crystals only let light through, not produce it, the white backlight's always on. If it's always on, even when the liquid crystals are blocking all the light, some light from the backlight will come through, making the screen appear greyish or blueish, especially in a dark room.
The only modern type of display to produce true blacks is OLED. Many phones tend to have AMOLED or Super AMOLED displays which are just a type of OLED.
OLED displays have little LEDs made of organic materials that produce their own light. Because of that, if an OLED display shows something black, all the pixels will turn off and no light is produced, showing an actual black image with no glow.
OLEDs also have no ghosting, which happens in LCD's because the liquid crystals can't change their orientation immediately to display a new color.
Unfortunately, while OLEDs do sound like the better choice, they are very expensive to produce compared to LCDs and also, the blue OLED subpixels tend to lose their brightness faster than their red and green counterparts, shortening the life of the display. There are some methods to prolong their lifespan like using a 4th white subpixel, but I've only seen it on very expensive TVs.
I have my original Vita from 2012 and I can see that the blue subpixels have lost their intensity because whites look a bit yellowish now. Makes sense because a brighter green and red will make yellow.
I hope that wasn't too long but I wanted to explain about the different types of display technologies and why most screens glow in the dark instead of showing the color black
not to mention the burn in issues that amoled displays have.... thats why I prefer not so deep black over the burn in.
It's not true black for me considering Xiaomi haven't used an OLED or AMOLED display.
