Nice screen on the Skyrocket, but the color is off, particularly white. It makes reading an ebook miserable. Fortunately, it's easily fixed.
First go to Settings/Display and uncheck "Auto adjust screen power". (Thanks to Shmegmaking for that tip!) This won't change the color, but will prevent the display going way too dim by itself while reading black text on a white background. it will use extra power though. But if you read text on a white or light gray background it's well worth it.
Second, correct the white balance. It's WAY the heck off. I used an Eye1 Pro Spectrophotometer to measure and correct my Skyrocket's white balance. You can just use my numbers to get the same result. You have to download & Install "Screen Adjuster" by "netman" from the Android Market. Then use these settings:
Red +31
Green +12
Blue +0
Brightness 100%
Contrast -0
Go into options and check "Autorun"
White is dead on with these settings; reds, greens, and blues (the primary colors) are much closer to correct.
EDITED TO ADD:
The main problem with the above settings is that grays are too warm. (Red) the Skyrockets display is not linear so compromises are required. The above settings give perfect whites and very good bright colors. Grays and less saturated colors tend towards red however. The Settings below will get mid level grays and colors to a very good level. Whites and bright colors will be a bit cool (Blue) and dark grays and dark colors will be a bit warm (tend towards red.) But overall, this is as close as you're going to get this phone I think. (Until somebody comes up with an app that allows gray scale calibration.)
Red +24
Green +9
Blue +6
All else the same.
NOTE: they took into account the screens inaccurate color when they did the stock wallpaper, so it doesn't look nearly as good with these settings. Pictures and whites look MUCH better though.
Some people prefer a cooler white for reading. If you use the top numbers, you can try changing Blue to +8 if you find this is the case. (If you use the bottom numbers you should be golden.) Less would be good; if you go too much higher you'll start getting further away from accurate colors. Some e-readers--like cool reader--allow you to adjust the color of the background in the app. That would be preferable to changing the settings I've given for "Screen adjuster". That way your pictures and videos will retain accurate color.
The screen won't be quite as bright with these settings. I think they tuned the screen for maximum brightness in the store, the same as they do with TVs. Kind of like using "Dynamic" mode on a TV, it gives a lot of "Wow" factor at the store, but after using it for a bit you notice the colors are wrong.

I'm going to look into this
I think it shows promise but the red push was hurting my white levels too much.
Your whites were too red with this? Which set of numbers were you using? With the top numbers the whites should be dead on, with the bottom numbers white is very much on the blue side. What were you using as a white reference? I've only got the one phone, is it possible that Samsung QC is so off that individual screens vary that much?
With the top numbers, dark gray goes to red too much, with the bottom numbers dark grays should be a bit red, whites should push blue. It's the best compromise I could come up with.
Everything looks completely inaccurate with either set of numbers/settings. I think it really is like someone posted above, where it depends on your individual screen.

That's going to be true regardless. The Skyrocket--and all Galaxy SIIs--are notoriously innacurate with colors. The bottom set of numbers should give you cool whites and warm darks. If you adjust it for accurate darks, white is WAY the hell off. That's the factory setting. If you adjust whites for accuracy, dark grays are WAY red. By adjusting the mid level grays--the bottom numbers--you'll get warm (reddish) grays and cool (bluish) whites. If you read black text on a white background, or read web forums with light gray backgrounds and white text, the factory settings are completely out of left field and unuseable for many. The bottom set of numbers corrects that enough to be pleasant to read with at the expense of reddish dark grays.
What would be great would be if someone made an app that let you adjust the color at different gray levels. Then you could get a far more accurate gray scale calibration.
Came up as not compatible for my device.
Nevermind my density was changed
I wanted to make clear, this isn't my app... I found it on the market and used my spectraphotometer to get the settings is all.

Thanks... Yeah I understand calibrating the gray scale, etc... I might have done a few calibrations here and there. The lower range of the gray scale will indeed push red with these numbers. There is currently no way to calibrate the entire gray scale. To get whites (The top end of the gray scale, above 180, 180, 180)) to a reasonable balance, the low end (below 100, 100, 100) is going to push red. If you want more accurate dark grays, (bottom end of the gray scale) your whites (top end of the gray scale) are going to be way, way off. So much off that many folks, myself included, find them intolerable. By calibrating the middle of the gray scale, (127, 127, 127) you get tolerable whites and tolerable dark grays. If you don't care how far your whites and light grays are off, then you should leave it stock. If you want a better compromise for the whole gray scale, the bottom numbers are good.
A proper gray scale calibration would allow at least 4 calibration points, 20 ire, 40 ire, 60 ire, and 80 ire. Without that, and as horribly unlinear the Galaxy S2 variants are, you have to pick one point to calibrate. Stock they pick around 20 ire it seems, so 60 ire and above is ridiculously far off. By picking 60 ire to calibrate, 70 and above is reasonable and 40 ire and below is reasonable, but does push red. It's basically pick your poison. Stock is calibrated for darks, I've given numbers to calibrate for mid level grays and another for whites. Whichever looks best for you is what you should use.
Yeah, I just received my Skyrocket yesterday and I noticed right away the whites are incredibly washed out with a blueish tint and I was worried something was wrong with my phone...I guess it's a universal 'problem' with these devices. It sucks to be honest, but I will live!
This worked great for me. Thank you. Huge improvement.

As it seems there are a few threads on auto brightness and color issues, i figure i should do the best i can to explain how it works on the S4, and mobiles in general. I work in Television/Film and have been shooting for almost a decade.
ANY QUESTIONS, feel free to PM me, i'll probably ask for very specific photo's (ISO/WB and other data) so i can help you in a professional manner, and i'll try to reply within 6-8 hours. No one should live with a bum screen!
To fully understand what im trying to express, load the attached image onto your phone, and on a bright sunny afternoon, print out the attached image on a small piece of decent photo paper, grab your phone, and find a room in your house that has only fluorescent lights and close any windows or shutters.
Look at the photo in the sunlight; note the colors. Now go inside to the fluorescent dark room, note the change in what the colors look like, and that white is still pretty white (thats your brain), then turn your camera flashlight on (LED), and note the changes in color again (some reds may look purplish or greens bluish), but white still looks kinda white (should look very light blue). Now repeat and look at the print out versus the same image on your phone screen; it should match best under 6500k lighting, but still be off (thats a printed image vs monitor thing though). Also depends on your printer ink type (dye/pigment), color space, etc etc etc. Your eyes take raw data in, but your brain does the magic, and says 'nope, thats white', so you perceive it as 'white' or 'white enough' and you 'know' it is meant to 'represent' white.
Hardware - This includes an ambient light sensor. The way these work is similar to metering systems in cameras; they measure the amount of light hitting a photodiode. Even in high end (DSLR) cameras, sometimes the light meters are junk. On cell phones, they are typically pretty crappy. The iPhone 5's have excellent ALS (ambient light sensors) and they ramp up/down smoothly; much better than any other device i've used.
The way the ALS works in most devices is simple; there are several photodiodes, each tuned for a specific spectrum of light. Say two for 3200k, two for 6500k, two for whatever else, etc, and they basically average the reading, apply a curve, and adjust the screen appropriately. They do NOT accurately measure color temperature very well, and 'see' brightness only in limited spectrums, meaning their idea of what 'bright' and 'dim' is may be vastly different from the human eyes' perceived 'bright' or 'dim'. Also, the 'curves' applied don't match up that well with how the human eye perceives brightness; its really amazing we can fake it as close as we can, really, but most of the magic lies in your brain.
Lighting - this is kind of tricky; and i don't feel like getting into it too deeply, but what you perceive as 'white' is mostly dependent on your brain; not your eyes or the lights around you. Think about reading a book (a real book) inside a library under fluorescent lights; the pages are white, even though the color temperature might be 5000k or 6500k. Now that same book outside; thats 5800k. Now under some old incandescent lights; that might be 2800k. Yet you know it SHOULD be white. Thats your brain. And thats reflected light; its based on the ambient color temperature around you; so reflected light 'looks' white or blue or whatever.
Your phone screen (galaxy S IV) is basically white balanced at 6600k , so it will appear most white when around lighting around 6500k, which is on the bluer side of daylight/cloudy and indoors.
Screen Mode - The Galaxy S IV has a feature that allows it to dynamically change based on the ALS, or can be overridden by the user, which mostly affects color gamut, and either amps up contrast and saturation while shifting hues slightly, or flattens them to a more realistic (usually most people prefer high saturation/high contrast images) image.
Sampling frequency - i have no idea what the ALS sensor samples at, or any definitive specs on the exact sensor and how it interacts with auto brightness, its priority, etc (yet, ive emailed Samsung and i wouldn't mind coming up with a simple app to adjust this if i can figure out the sensor specs and their software). But certain lights (fluorescent mostly) flicker at either 50hz or 60hz depending on their AC current, which may, at times, interfere or give bad readings to the ALS depending on the ALS sensor reading timings (again i do not know exactly what those values are, i suspect they are long as my S III and S IV typically react about a half-second behind lighting changes).
DETERMINING IF YOU HAVE A BAD DISPLAY
All together, it works pretty darn good, if a bit slowly, but there seems to be a lot of confusion and people wondering if their screen is bad. The BEST and EASIEST way is to go to any cell store or mall, and compare YOUR screen and the SAME image to another S IV, with the same settings. The best settings for this are to turn power saving OFF, turn off ALL power saving apps, turn auto brightness OFF, turn brightness up ALL THE WAY, go to 'settings', 'display', 'screen mode', and change the setting to 'movie'. Compare several IDENTICAL images or pages. Then change the 'screen mode' to 'standard' and compare the same images.
While doing so, be sure to check out images such as the one i provided and make sure the colors match, grays are grays or at least the same slight caste of pink/green/etc, and while doing so, TILT THE SCREENS at various angles together (level surface, side by side, tilt to 45 degrees at the same time on all 4 axes), and look for discoloration or bleeding; if you see big differences between two or three other phones and yours, you got a bum screen. I haven't seen a 'bad' one yet, and i made the poor AT&T guy open up five of them and let me play with them (AMOLED also has jet black splotches with full blacks in a fully black room; i wanted the screen with the least noticeable splotches).
Thanks for this. Question though. When I pull my keyboard up to type on something or if I'm in a YouTube video and I tap the screen to bring up the progress bar the color shifts dramatically. I've tried many settings and it always does this. Also tried it on another s4 multiple ones did the same thing...

The white balance can actually be calibrated by changing the calibration levels of the LEDs sitting under the screen

ok, do me a favor, I would prefer if you had either a prosumer camera you could use, or better yet a DSLR you could borrow that i could guide you through how to take two shots of the differences with all the important variables locked down so i can figure it out for you. I believe the screenshot feature ignores the 'Screen Mode' settings, as it should (you wouldnt want a screen mode dictating recording colorimetry options), so it does require real photos to figure out.
Have you changed the standard 'Screen Mode' setting or left it at 'Adapt Display' or 'Dynamic'? Those will keep changing it; Professional photo and movie are more flat, but they do not change. Again disable power saving mode, power saving apps, turn off auto brightness, (in this case set brightness to where you want it) and check it out again; if it doesnt change colors, (which it should not), you have no issues; its a normal 'feature' of the device. The idea is to limit all variables. Try that and PM me the results. If the colors no longer shift, the issue was 'adapt display' or 'dynamic' Screen Modes. Auto brightness/powersaving mode/power saving apps should only affect brightness; we are only disabling them to limit perceived changes.
To try to trouble shoot this, change screen mode to a static setting like 'professional photo' or 'movie' in Screen Mode and turn off auto brightness, turn off power saving and turn off all power/battery saving apps/etc, bring up a Youtube video and play it, then bring up your keyboard and see if the color shifts (it shouldnt if you have changed Screen Mode to Pro Photo/Movie and disabled powersave/all battery apps/auto brightness). Then let me know if that fixes it via PM.

problem is most calibration settings/programs and methods i know of are non-pentile and are mostly software fixes for what ive used; AMOLED is different PenTile (RGBG) than what i tried to fix before which was Motorola Atrix 4G PenTile (RGBW, red green blue white), CCFL LCD is way different (more what im used to, as well as LED LCD and even IPS is easier as it is still RGB), and all the curves software etc are all proprietary to manufacturers. Granted controlling just the R/G/B/G LED's would help, but getting the curve right and correcting might take longer than the Galaxy S V arrival. I spent months calibrating all my gear; most of it is 2-3 years old, and at least 6-12 months old before i get it all settled and can rely on it for a given job. Usually i rely on calibrated displays, knowing my own color limitations, RGB histograms, vector scopes, etc (i have a very slight red/green color weakness, but extremely sharp vision and i know how to work around my limitations).
I actually emailed Samsung about this for as much information as i could get (not much so far but im digging). I have a friend playing with LUT curves on his S IV and he says its a close second to the iPhone screens for AdobeRGB in 'movie' mode, which i happen to agree with; its pretty flat, but the contrast on greens is still high, which again is a PenTile RGBG specific issue; we are both vets of backlit RGB panels. My friend also works with the same company i consult/represent; it took him almost three months to properly calibrate LUT curves between a single sensor and a simple 480P CCFL LCD display, and that was with full manufacturer support. Colorimetry is a science.

Same here. Thanks for the write up but I'm seeing the same thing.
I dim the display with the Screen Filter app for reading in bed and whenever my keyboard pops up (SwiftKey, TouchPal or stock) the entire screen gets a green cast. Under these conditions it is very dramatic.
I use manual brightness and turned off the Autoadjust Screen Tone setting
Some other apps exhibit a fluctuation in color cast when I put my finger near the screen which is double weird. :-\

yep, i have some old LG CCFL LCD monitors with a claimed 2ms (more like 6-10ms) response time from 2006; they were about $300 each back then. i also have a new IPS with 30ms response time; it is annoying.
also some pentile displays are slower between subpixels; my Atrix 4G had very slow blue white pixels (RGBW) so you had a weird dimming as well when scrolling through texts.
Settings, Display, disable Auto Adjust Screen Tone' as well, its a power saving thing i forgot to mention in the first write up.

Has anyone else noticed a color and contrast shift from the top to the bottom of the screen? In very low brightness settings my screen gradients from crushed black levels and a reddish hue at the top of the screen to a acceptable black levels and an more green hue at the bottom of the screen. I can try to get some pictures with my DSLR tonight to illustrate. I'll have to compare to other S4's in the same scenario. In every day use its not too noticeable, but while watching video in a completely dark environment with the brightness all the way down it now bothers me some.
Anyone have a similar experience? Thanks!
Yes I notice it. It fixes itself if you change the brightness with an app. so I'm guessing its a weird kernel thing. It only happens when the keyboard is up

I notice it with or without the keyboard. I use the Display Tester app to display a full screen white or 50% gray and now that I look at it, the red hue at the top of the screen is visible at all but 100% brightness levels. What app were you using to dim the screen, I would like to try it out.
Here is an exaggerated image I made showing the gradation (50% gray). The top of the screen would be to the left. Black levels get crushed at the top of the screen also.

The Z3 is using an IPS screen so the blacks won't be true black like what you get on an amoled. Pixels are not turned off, but rather dimmed. Also, since the Z3 uses blue leds instead of white, that could be why it shows a blue/grey instead of a more natural black. Don't have an exact fix but you can try adjusting your color settings to get your result. Best of Luck.
I have read somewhere that its by design and only seen on max brightness to make it easier to read something in bright sunlight
hey guys, I'm about to buy a new Z3, but i'm confused about colors,
I really like the white one, but I'm afraid that wallpapers will make a conflict with the white color of the phone , I mean the white bezels of the phone in the white version, will I face color mismatching with 'em among different situations/wallpapers.
so is that right ? if any of you have the white one please tell me about your visual experience,
opinions, people !
Find a white wallpaper that you like. Mess with white balancr in the display settings until you find the most neutral white. Personally I think xperia z3 is far too blue, and given that the blue pixel is the most important in preserving the whiteness of the screen, I find it best to preserve the blue pixel as much as possible. Which is why I turn the red balance almost all the way up and the green balance somewhere around halfway, until I find it's balanced to my liking. This way you get a softer and purer white, whilst retaining the life of the blue pixels. And if you find the right balance, you'll find it also matches your case. Do it indoors in a naturally well lit room, without a room light or lamp. Hope this helps.

ahem, up!
There are plenty of wallpapers out there. Just get the one what fits your color. White is the best as you wont notice any fingerprints where as black is a fingerprint magnet.
My display is green-tinted quite a bit, I didn't notice the exact problem at first because my display wasn't too warm or too cool, it just looked odd. I only realized it as I went to tweak the display options, reducing the green slider by about 80% brings my display to the correct tint, where the whites are the same as real life whites. Red and blue are correct in my display, those don't need any tint correction
My tint is really a non-issue because it can be fixed completely with the sliders, but it seems like a lot of people are having problems with their displays on the S8, compared to the S7. Have any of you had these similar issues, even small ones like mine?
'Real life whites', yeah but based on what? Most 'white' things arent white, they are blue tinted. Real white is quite creamy and slightly green to some eyes. Do you have any pictures?
My orchid had it bad. Took back for exchange and took three tries to get one without it. Bought at BestBuy, red tint that is.
I didn't notice anything yet that is close to "That's odd!".

I didn't even notice the tint until it was being reported. I lined up all my phones and just opened up a white page and u could definitely see more reddish hue on the S8+. I simply used the slider to adjust. Problem that I didn't know I had - gone.
slightly redish on top and right side. rest is fine. I'm not sure if I wanna turn it back in. AT&T said if I returned it it was a restocking fee. but can I just go to them and exchange?
Mine have the red screen tint even after the update, and if I try that fix and put it on cold and reduce the red, I see some rainbow effect on the edges, more proeminent on the left side and top, and it still have some reddish tint on low left corner, and that completely messes with my eyes...
I've had an S7 Edge and never experienced any of this problems, I was with it yesterday and it was amazing compared to this S8+. It's a shame that samsung have such a poor screens on this flagship.

has anyone else noticed this?
Weird Green banding in dark mode and low brightness
Did a factory reset for battery purposes and noticed this... didn't think i saw it before I reset it??
Soz for the bad pic but basically the left side has a big green tint

Some users have reported that in Reddit and SamMobile. I posted a thread a couple of weeks back here:
https://forum.xda-developers.com/ga...n-affected-t4153251/post83406075#post83406075
I have reported this in this forum as well. Mine is more a yellowish tint to the overall display. When you look at chrome or YouTube in dark mode, you'll notice the blacks aren't as deep. I have come across 3 different note 20 ultra with the issue which leads me to believe most if not all units have this even if not many ppl report it.
I saw it yesterday when its on low brightness and dark mode on. Even when watching prime video there is green tint though I brought whole green hue to 0
Any of my devices with amoleds look green to me. Must be 65 y.o. vision. Did the trick of turning down the green all the way. No dice.
I use a neat app from the play store called Screen Balance which is a Godsend. You can really fix the tinting with it. I like cooler colors without green and it does the job... but... the saturation and contrast in the Ultra just isn't up to snuff. I only notice it when I put the phone side by side with the Note 9. I have Screenbalance installed in both devices, and the 9 beats the Ultra firmly.
Thoughts or updates?

You don't need an app for colour filters, it's also in Settings > Accessibility > Visibility Enhancements > Add colour filter
And also in the same location > Colour Adjustment

All I saw was Add Color Lens but at the lowest number washed everything over with the chosen color. Same with color adjustment-barely any changes with the sliders even though I do have the green at zero.
That app is the ticket for me. It has various filters for different screens and the one I chose I adjust for *just* a hint of blue-takes out the greenish without putting a visible tint over everything. I do it on every device I have and for me, works great. Believe me, I've tried everything with every amoled and it's the most workable for me, and I'm anal about this stuff. :rolleyes

Ah I'm running the Android 11 beta so looks like they renamed a few things, but they're the same settings, yes I tried those settings too and got the same effect, I assumed that was what the app did too, looks like it works a bit differently to the stock settings method.
Great you found a solution anyway

I don't have the green tint issue thankfully, I did install it to have a look but the free version is limited to one colour and setting so couldn't explore it much, but have bookmarked it incase any future devices suffer from it, thanks.

Thanks for the "Screen Balance" app! This app seems to be the only one that gives the fine tuning for white balance without turning Vivid mode ON. It has significantly reduced the yellow tint on my N20 Ultra. I did notice however that it makes the text on screen a little bit less sharp.
I don't have the green tint either. Was all in my head.
Then again maybe not. Lol. I see it and don't see it at night. Regardless of 120 or 60Hz.

I did by going into visibility enhancements, personalized & chose the colours & voila natural mode is now much more white & saturated.

I did that also, but there was still significant yellow tint. The app helped me reduce the yellow tint quite a bit

Well the green tint keeps coming and going on mine.
Noticeable at low light and night time usage when device is in dark mode. Sent it back., I’m nothaving this issue hover over my head with no warranty after dropping over 4 digits on this device.

Interesting.....I guess I'm one of the few lucky ones with no green tint or I'm just not noticing it....let us know how your new one is !!! The only "problem" I've had with mine is a little speck of dust inside the camera module but its not on the lens so it doesn't affect my pictures ??*
