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!

My brothers has cool whites and I have warm whites...yet our panels are both Sony...so I don't get it.
mine is also a warm-toned screen, nonetheless it looks great
I posted about this yesterday but it already got buried. Unfortunately you can either hassle with taking it back and hoping for a more blueish white panel or you can get used to it. I hated the look when i unboxed, I have the same yellowish tint on white. But im already used to it for the most part. There is an app on the play store called "Screen adjuster" that you can add some blue back in but its not perfect and it has to run in the background i haven't tested to see how much of a load it puts on the phone if left on all day. Also a good app to use to visually inspect the colors your panel is showing is "dead pixel test". So software can be used to help the tint, but as far as a permanent solution, I believe that would be up to HTC. Maybe some devs can do it eventually once we have s-off.
I've just starting to really notice this, and its driving me nuts.
The whites are not white at all, they are more yellowish eggshell (or as I like to call it 'light puke'). You can really notice it when your in natural light. I held it up to something pure white and you can see an epic difference.
Does this not bother anybody else? I forget, but don't some ROMs (for other phones) have options to change screen tones? Is this something that I can look forward to ? Or perhaps my eyes (and mind) are just playing tricks on me.
I dislike 'warm' tones a lot. I wish I gotten a 'cool' tone phone instead, I can handle the blue tone a lot better.
I wonder why this is I mean it isnt like amoled n the screens should be.the.same.... Maybe dim lights inside?
Root it and try chainfire 3d, it has the option to change screen tone in I believe the pro version. Added bonus, works with all roms to my knowledge. I haven't tried it yet myself as I'm completely happy with the tone on mine, but I used it on the og evo for a long time.

Thanks, I'll give it a try since I'm already rooted. I messed around with 'screen adjuster' and 'filer your screen' and neither seemed to do the trick.
EDIT: Looks like I'll have to wait a bit longer to play with chainfire 3d. Requires S-off (or probably just unlock bootloader). Only have root. But chainfire looks promising.
This was a problem on the One X for AT&T but most of them cleared up after a week or so. My advice would be to keep the brightness up for a while when using it.

We have two EVO LTE and one of ours is much cooler and blue and the other is much warmer. How do you check if the display type to see if they are different?
My screen is warm also. At first I thought it was the ZAGG HD screen protector that was causing that yellowish tint, but after I removed it, it was still there.
If anyone with two EVO LTE phones can post a side-by-side picture of the warm and cool screens, I'd greatly appreciate it.
TIA
Here is a picture. Its not the best quality so it might be hard to tell a difference. The difference is much more apparent in real life.
Supposedly its due to the adhesive. There is a thread about it in the HOX forum. My screen seems to be whiter than it was a week ago but that may be a placebo effect- I need to do another side by side comparison with my iPhone to tell.

I was dreading a problem like this. I can deal with blacks not being black (have to deal with it with the very nature of LCD) but whites... Yeah, they need to be white.
Here's to hoping my device doesn't have this issue. I will update this post with news.
get an app called screen adjuster
then increase the blue a little bit, to about 15 or so
woooooorks wonderss!!!
On my NS4G, there was a kernel mod developed by SuperCurio that allowed you to adjust gamma levels. I always ran my phone with very cool blue whites.
Maybe something like that would be possible for the Evo?
I think I have the warmer screen color. Things like this doesn't bother me at all. I've seen thread like this everytime a new phone comes out. After a few week your eyes and OCD levels will adjust.

You can def tell the one on the right is the warm though. I'm sure in direct natural light the difference is huge.

Same. I can deal with the black but not the whites. Whites need to be crisp and clean not yellow. I repainted all the eggshell whites in my house to pure white. To me it takes away the crispness of the screen.

Man you hit the nail right on the nail. I had mine set at 14 for the past three days. It helps but it still isn't ideal. Plus its consuming resources.
dont think its an adhesive bonding process still "curing"
i think the color temp is permanent.
hopefully a dev will allow color temp change because its a little awkward staring at my pc monitor, then looking at the phone's brown and yellow drab lcd tint.

This is what I am praying for. But enough people have to be annoyed by it for somebody to do something.
The best test is to open the settings menu (Evo white) and compare it against a piece of notebook paper (real white). Its gross.
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.
Basically, my S8 Plus' colour balance seems to look nicer than my M20Pro
I like my display a bit warm, even on the warmest of colours (In the settings) my M20Pro still looks extremely washed out and light / white.

Thank you for the response, just tried this, still not getting the same types of colours compared to my S8 plus.
tomorrow I'll get my camera out and I'll try to show what I mean.
Just adjust it to the way temp you like. I liked the colder temp. The screen makes the whites on the pixel 2 xl horrible
I like my display as white as possible. So I like it on the cooler side
I am a little disappointed in the warmth of the screen. Yes, OLED means perfect black - but the screen is otherwise quite cold even when the 'eye comfort' is set to vivid & warm. In fact, laying this phone beside my 1st gen OPO (which was a textbook 'cold' LCD), they don't really look all that different.
Obviously Samsung tends to go to near garish, eye searing ends of the spectrum when you have things set to 'vivid', but my 10" Tab 2 is so juicy your eyeballs explode and dribble down your face. I wonder if this screen is simply cold by hardware design or if it would be possible through software to make things warmer yet. It isn't a deal breaker, but putting this thing next to an iPhone XS (which is also considered quite 'cold', explained insistently as 'more accurate'), the XS actually looks somewhat more juicy than this thing. I don't want accurate, I want to get radiation burns from the ridiculous over saturation.

This must be a defect then because the display is better than the Note 9 and S9 plus when its not going green. If you really need an unnaturally warm tone, it should be perfectly doable in the settings if your phone isn't faulty.

What is it with people loving these horrible warm displays? Get an iphone x they have lovely yellow whites with truetone turned on. I wager you'll love that.
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...

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.
