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...

Just hoping for a fix for it
The white balance can actually be calibrated by changing the calibration levels of the LEDs sitting under the screen
Lets hope for the best

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.

I bought the s4 the first day it came out, after using it for couple of days i started noticing weird stuff on my photos, especially on low light photos... i went to att and one of the rep said its a known issue its called "elephant effect" im into photography and i havent heard that term before, he also said that it will be fix on the next update... so i went home and did some research about "elephant effect" unfortunately i cant can find anything related with my issue... i also did some pixel peeping and im 100% positive there's something off on the display of my phone.
Sample photos
These photos are just screenshots
You can see those weird artifacts on the pictures, i also compared my screen display to my coworker's phone and my phone was way off...
What i would suggest for those who wants to buy the new s4 or currently users, is to check the display by taking a photo on a low light and do some pixel peeping...

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.
(Sorry for the bad image compression, my screen doesn't have the extreme banding in it!)

I tried that and it made little to no difference on my phone. I went to the AT&T store on my lunch and compared my phone to the display unit. My phone has a noticeable difference. The rep at the AT&T store suggested I take it to the local repair depot... I've never been there before but I hope they don't try to pawn a refurb phone off on me to replace my 17 day old S4. I'll let you guys know what I find out.

Hi my s4 have a yellow tint, i compare with other s4 and my s4 screen have much yellow in white screen, is faulty? Is possibile to fix it with gamma correction?
I'm using Waze app every single day for about 1.5 hour.
in the past when i had galaxy S4, after 2 month of daily use, i noticed on white pages i still see all the static banners and buttons of waze.
baisically, using Waze in daily basis, burn-in my screen in the static area of the app like the up and down banners, speed meter etc...
Can it happen also in my new galaxy s8+? what to you think? did the amoled technology haven't changed a lot in the past 4 or 5 years?
There is a new feature in Waze called battery saver, it dims the screen when you are over a certain speed and a certain distance from the next instruction, that might help with it.
Though to be honest I use it for about the same amount of time everyday and don't even think about any burn in, its definitely not something that I've noticed happening on my phone so far

Definitely can still happen on the s8+. I'd recommend not having your screen excessively bright while static images are on screen if you can help it. It's a pain but this is just an unfortunate trade-off with these beautiful screens.

It's not a trade-off. It can happen with virtually ANY type of display. LCD, LED, OLED, etc. No mobile phone display is immune.

I'm sorry if you dont like it but its the truth. I absolutely love the Samsung phones so I'm not against the phone. I've had the Note, S3, S4, S5, S6E, S7E and now the S8+.
I'm the first person to correct somebody wrongly bashing these phones but in this case it is what it is mate. Its well documented and accepted as fact that screen burn in on Amoled is more prevalent than some other display technologies. You need to be a little bit more mindful with Amoled if you want to keep the screen looking nice with heavy use.

Based on your first response you obviously didn't grasp mine at all whatsoever. I wasn't comparing Amoled directly to any other screen technology but the fact remains that the prevelance of screen burn in is generally higher than other screen types in general. That's not just conjecture on my part.
Its accepted fact. Also I'd appreciate it if you dropped the childish, rude and flippant attitude towards me. I was simply responding to your straw man argument.

There was one week where I used it excessively. And I kept the screen full bright. When I saw the screen burn in with the arrow of waze navigation. I started looking up on the Internet to solve the burn in issue somehow. That's when I found out that it's a common issue on amoled screens apparently. And the only way to solve it was to send it back to Samsung for a repair or replacement.

Yeah unfortunately its one of those things that you just have to be mindful of, even when you're not on full brightness.
I was pretty lucky with most of my galaxy phones especially considering how heavily I used them, although my S7E was an exception.
I still have the phone and after just 13 months you can clearly see discoloration on the screen and admittedly very feint burn in on UI elements ie. the status bar. The screen discoloration is pretty bad and perfectly matches the YouTube app, where the video is playing up top and the static white comment section below put uneven "wear" on my screen. I'm now trying to make a habit to watch longer YouTube videos in fullscreen to avoid a similar result.

I work for a carrier and never in my 14 years have I seen a LCD screen burn in I have however seen multiple AMOLED panels with burn in especially demo phones (yes on all day rolling content but so are the LCD models) this is a risk with organic displays to his point is true it is a trade off whichever way you sugercoat it
Wow! So i watch a lot of youtube and i never really watch videos in landscape mode....well i went to google something and the pages background was all white i noticed a line across the screen its barely there the top of my screen is white the rest of the phone is a slight off white is this a burn in? The reason why i mentioned youtube is because when i measured this line i kept my finger nail there to match the youtube video in portrait and sure enough that line matched where i kept my finger nail on that line wtf man lol is this now a permanent issue i never go full brightness but i admit im on youtube videos heavy...smh i thought id never have a problem with this s8 plus I've had it since launch

That's always the main issue when using Amoled displays. It's just part of the technology unfortunately. They look great, but they are basically an organic technology that degrades over time. They can degrade unevenly depending on what you're viewing/doing as you have witnessed. Navigation bars and status bars are usually the first to be noticed. I usually disable mine and use gesture controls for this reason.
P.S - Get ready for all of the Samsung/Amoled fanatics that are going to tell you that it is impossible and that you're using your phone wrong. [emoji6]

Oled displays generally heal over time by themselves from burn-in if it's not too much marked, clearly if the fixed image pattern that caused it will no longer be displayed on the screen.
Many apps are available on Google Play that could help shortening this healing time, for example:

Oled displays generally heal over time by themselves from burn-in if it's not too much marked, clearly if the fixed image pattern that caused it will no longer be displayed on the screen.
Many apps are available on Google Play that could help shortening this healing time, for example:

LCD burn in, or image retention does go away. Amoled however, does not. The only way to make it "go away" is to degrade the other pixels the same amount as the others. If the navigation bar for example is where the burn in is, the only way to fix it would be to let the screen stay on on the opposite pixels so that they will degrade to the same level as the others. Amoled technology is an organic technology, which means that each pixel is slowly dying each time the screen is on. If some pixels are used more than others they will die faster. It's just the science of the display.

Wow! So i watch a lot of youtube and i never really watch videos in landscape mode....well i went to google something and the pages background was all white i noticed a line across the screen its barely there the top of my screen is white the rest of the phone is a slight off white is this a burn in? The reason why i mentioned youtube is because when i measured this line i kept my finger nail there to match the youtube video in portrait and sure enough that line matched where i kept my finger nail on that line wtf man lol is this now a permanent issue i never go full brightness but i admit im on youtube videos heavy...smh i thought id never have a problem with this s8 plus I've had it since launch

Lol, reminds me of antennagate and when Steve Jobs said "You're holding it wrong"
Yeah... leaving static images on amoled on for extended periods of time is never a good idea.
Google should know better than this too. They should force the UI to fade to black when a video is playing in portrait.
My S8+ got burn in after about 2 months. It was also having other issues. But anyway Samsung replaced my display under warranty. Been a few months since and this one isn't having that issue.
just like mine
I got the same freaking thing same burn in as yours the line is where i watch the videos im surprised it also happened to you. The top line is more whiter.
Always on Display = Screen burn in
So just to be on the safe side, it would be better to disable the AOD (always on display)?
Anything black on your screen, helps decrease burn in.
Personally, I never use AOD. Maybe I am being over cautious?
duplicate post
Top is whiter bottom is darkish yellower
Same thing is happening to me and same circumstances with s8+. Occasionally youtube glitches and goes fullscreen in protrait making the whole screen black and keeping the video portrait which is cool but that rarely happens to me.

The aod moves around. Sammy has made this feature nearly percect mine is used every day for about 5 hours a Night and no burnin anywhere....

If you're actually referring to my post about how to show an amoled screen burn-in on this forum, before posting you should exactly understand what is being discussed...do you know what a burn-in is???
If not, then forget my comment, but in the future please explain yourself more clearly so we can understand whom and what you're referring to...
I see that you're a first time poster here on xda-developers... maybe this can help you:

Hi
I've been trawling through the forums for a couple days now to see if anyone has come up with a solution to, or a reason why Samsung doesn't leave the proximity sensor on while the always on display is active anymore (since the Note S10).
I know the sensor has been moved behind the screen. But it seems to function in the same way it used to. It still blanks the screen during a call, if I hold something over it up to about 20mm away. Just not with the always on display.
I'm currently using aodNotify as a sort of workaround. But would much prefer if the always on display just worked like every other damn phone!
Does anyone know the reason why Samsung has disabled this? Uses too much power? I Don't know.

Working in what way ? Mine works as in, it gets brighter or dimmer according to the light around me.....or are you wanting/expecting AOD to turn off when the screen is covered ?

Exactly, the former of what you said is all it* does when AOD is active.
In any case this is now normal operation possibly done to help save battery.
*I'm not sure that the proximity sensor is the ambient light detector?
I think what the OP is saying is that for example if you cover the screen whilst the AOD is on, it used to turn the AOD off before. It no longer does this.
Behavior started with the S10 series.

So if you had it in your pocket it use less battery?
Interesting.
On most other phones, and Samsung's prior to the Note 10. If you put the phone face down, or placed it in your pocket, the always on display would turn off to save battery. They no longer do this.
I wonder if there's a work around for this somehow.

It's not working on mine - is this feature removed on GW4?
Just checked my watch 4 LTE 44mm and it goes dark when placing Palm on it for some second's...
I guess mine has a faulty sensor. Old Gear S3 worked fine with palm turning off the screen. Not a very big deal though...

You're not alone - it doesn't work on mine either. I concluded that Samsung removed it/it's not a Wear OS feature, as it wasn't in the setup tutorial, and there's no setting for it. Although I have seen others like galaxys claim that it works, I'm not convinced...

Depends if you're in a hurry or not
Works on mine, too. The obvious questions are:
A. Is your always on display setting activated?
B. If yes, does your watch face have a dimmed view?
If a is yes and b is no, then placing the palm on the watch won't cause a change even if the sensor works. I had that issue for a while with a watch maker face that didn't have a dimmed view.

What if a is no and b is sorta, as auto brightness is on? *Edit*: Just checked with auto brightness off, still doesn't work. Are you sure your screen isn't just timing out as you try this?
If a is no, then b is irrelevant. If AOD is off, then the palm gesture should turn off the screen, period. The fact that the screen goes a bit darker proves that the ambient light sensor works, sure, but I'm unsure if that's the only sensor that determines whether the palm was placed on the watch. Might be multiple sensors?
Just saw your edit. I will test it.
Edit 2 after testing: my screen timeout is 15 seconds - the palm gesture is maybe 1 second. So that's not it.

Interesting. Thought maybe it might be related to using AOD, but nope, doesn't work either. Your's the regular Watch 4 or the Classic?
I use this feature a lot it works perfectly on my gw4
For me it works in both the cases aod on and off... Difference being with aod on it dims the screen and with aod off it completely blacks out the screen
It also silences the call and stops the vibration when a call is received

Classic.
I found in manual, that it should be working: https://downloadcenter.samsung.com/...210722/lock_or_unlock_your_device_d1e772.html
Not sure if watch reset could help, also potentially could be fixed with next firmware upgrades, unless there is faulty sensor

Reset didn't do anything - other than show me how poor the backup is on the watch, and force me to install SHM Mod again... I doubt it's a faulty sensor (as everything else, i.e., auto brightness, works fine) - maybe my palms are too translucent?
Works on mine when bought new and then now. In between I had issues. After buying the watch I tested everything. Then about two days after my screen protector order arrived. PLaced it on the watch and I thought all was good. Eventually this topic came up in another forum and I checked mine. It wasn't working. Whatever I did it just seems that the palm to screen off wasn't working as it should. So I did a reset, etc. Still not working. I thought, who cares? It's not really a feature I use everyday anyway but somehow for me that means there was an issue. Then as I was looking at the screen I realized there were some lifts on the perimeter of the screen protector. I removed it. Then I tested the palm to screen off. Not once did it NOT work. I let it go without a protector for a day or so and it was still working. Since then I didn't use the tempered glass protector anymore. I bought one of those film type protectors and now the palm to screen off is working.
Thanks @thephantom for the hint! Apparently it's working on mine as well, I just needed to put my palm much closer to the watch screen (in comparison to my Gear S3 where it was enough to put palm over the watch and not touch it at all), I'm pretty sure it should work for others too on GSW4, once you press your palm against the watch (touching the bezel with your palm with light pressure ) - it was just wrong expectation on my side from the other model...

Well, I'll be damned - that does work. In fact, using the ball of your thumb seems to work well, and every time.
