In some apps that have black gradient i can see a few spots and even quite a long line of dimmer pixels at certian black levels. Has anyone else seen this? is it a defective screen? Should I go compare it to an in store model and see if the same spots show up?

I have the same thing. From what I've read/heard it's the Pentile screen at work.. I'm still going into. The store later today to verify.... Once you see it you won't be able to shake it out of your head.
I first saw it late at night with all my lights off and I was close to the screen...now I see it all the time.

Hey everyone, I bought my HTC One S used, and at a discounted price because of screen burn-in. The burn-in isn't noticeable at higher brightness settings, but when there is a dark background applied, or when the backlight is dim, you can clearly see burned in areas.
Has anyone had any success using any burn-in removal techniques with apps like Display Tester?

What exactly is screen burn-in? Is it the same as the screen has different color depending on what angle you are looking at it? My experience is when i look directly on my screen, it show some yellowish in white background, but when i tilt it forward or backward, the white becomes white with no yellowish color. And when i turn it sideways it become pinkish.. do you think my screen is busted? Or is it what you call the screen burn-in?

^-That's a good example of what a screen burn (or is it image retention?) looks like. Found this image on Google just for the purpose of an example, it's clearly not from an HTC One S haha
My friend who uses the HTC Sense clock has developed minor screen burn from having the clock widget in the same place since day one of his phone

TC is probably referring to ghosting. Kinda like

or to a lessor extend but more common

Notice the faint icons? As to fixing it, I don't believe there is a way other than replacing the screen. It happens when an image is displayed without movement. It sort of "burns" into the screen, and when viewing something else, its slightly visible, thus "ghosting"
As for the yellow tint you see in the whole screen, I believe some displays are just like that.

tbh i wonder what would happen if you attempted to burn in the color inverted (dont do it, lol)
But most likely a new screen, which isn't too expensive.
If you had a big enough discount, it'd be no problem.
Hi, I am planning of getting one of this beast. After reading on the internet about possible amoled screen burn in after using it. Could somebody share his/her experience regarding this? Is burn in screen real problem or small problem with this device? Thanks.

Never heard of screen burn in issues with amoled screens. I've had the original Galaxy S for over two years and have had no issues.

I have very, very faint screen burn in at the bottom of my 7.7 where the status bar is. Can only really notice if I'm looking for it on a white screen, but more obvious on a red screen. I believe the only reason it happened is because I took it out in the sun with me one day and put brightness up to 100% for like 90 min while browsing/reading because before that my screen was flawless. I'd say if you can keep it at low brightness you should be fine. If you're rooted I'd get a hide bar app. In contrary to all this though, my Note II has no burn in whatsoever and I leave that thing on auto brightness.

Thanks for the heads up man!
My Tab is an ex demo unit and had some massive image burn in due to it being left on while on display with the screen overlay still on the unit, so i had the big O and the smaller icons burnt into the screen, i only really noticed them when viewing solid lighter back grounds, and as i have used the tablet more for the purpose it was meant to be used for rather than sitting looking pretty on display the image burn has all but disappeared, can only really pick up traces of the burn if a really look hard enough
Here is link for tab 7.7 screen issues.

It has been already discussed before, and my question is has Samsung fixed the issue yet? Most of them say is a manufacture defect. Or maybe it just Amoled technology at infancy.

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
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.

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!)

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?
So after using the phone for a week, I can see a faint line in the top of the screen which I find quite weird since I haven't used the phone at max brightness nor had any static images for long periods of time. I'd just like to know if this is something other people have experienced with their devices? There's also a slight green hue with white screen which is absent at the bottom of the screen. I only noticed it because of a black wallpaper that showed that there's actually a constant notification bar in the launcher screen.

Ok so you assume that this definitely is a defect? Too bad.. it's really really faint, but since I've seen it, it's always there. The home button from AOD is the most notable, varying by the brightness.

Is it burn in or ghosting?
If you are unsure about if your display is burning in or showing ghosting or both, use a full screen gallery app like QuickPic. Get a gray image and view it. With ghosting you will immediately see the navigation buttons but they will fade (scroll about to a few other images to help it fade), if they don't fade, well the display is probably burning in. You can easily download the checkerboard pattern with a google search.

Thanks for your reply, I also have a suspicion that it might be due to the fact that I used navbar to make the navigation bar entirely black, making the navigation bar "not to burn in" so to say. I disabled that and will see if this has any effect. I also disabled the home button on AOD. If it is burn in it is extremely light still, and only visible with gray backgrounds. I have a feeling that it might be fading away, or my eyes are just starting to give up fingers-crossed, the latter probably the better since I hate to be this nitpicky.. :silly:
Also I haven't read about anyone else suffering from this green tint/hue at the top of the screen. It's not so prominent when I lower the green values or when the screen is dimmer. It's this green stripe that sort of leaves this completely white gap between the bezel. Not very easy to explain but it is easy to distinguish with white backgrounds. It almost looks as if the panel isn't aligned properly and a line of pixels is "out of bounds". Weird if I'm really the only one with this symptom..

It's because that Samsung S8 and S8+, have problems with some wallpapers. I get a faint status bar on for examples some wallpapers, because of their aspect ratio. So if it's that, try out the inbuilt wallpapers as they don't get this problem. Don't get a flip, if it's not that you ment!
Try and take a screenshot. Just say Hi Bixby, take a screenshot.

I wish it was, though the green hue is noticable on completely white and grey backgrounds. I did notice what you mean though when I used a black wallpaper that had this weird bar at the top.
I get that too on some black wallpapers, but if i use a builtin black theme the strange oversaturated dark bar disappears.. and when I take screenshots the bar stays on the screenshot.. so it's not the screen having prob..

Yea, but I'm talking about whites now. With a solid white background the top has this green line, not with blacks.
try to screenshot it if the green line appears on the image when you scroll around..

if you zoom in on the left part you will notice a slight over saturated bar.. but on the original wallpaper there isn't.. it only comes out when I use wallpapers that are not built in on the theme.
Ok so now I stumbled across this thread on reddit https://www.google.fi/amp/s/amp.reddit.com/r/GalaxyS8/comments/682xmo/my_screen_is_a_little_uneven/
I have a strong feeling I'm experiencing the same problem, though at the top there is this white line that goes through the green area just below the green line at the top. Don't know if this splotchiness is a completely different issue..
Update on my situation, I sent the phone to service center through my provider. We'll see if they see what I see. It feels so bad to be away from my Samsung.. I hope they treat it well. Will update once I get updated.
I'm quite surprised but today I got an update on my situation. They swapped the screen and battery so my concerns seem to have been justifiable. I'm sorry that I couldn't replicate or get a picture of my problem.
Now received the phone, new problem arose. The so called "light bleed" that many have been complaining about, but for me it's literally everywhere. It's in the receiver, in all corners and all sides. Damn, such a shame to be sending my phone to service all the time.. Guess I won't be touching any curved screens anymore.
Edit, And to all those who say the light bleed is normal, I didn't have it before the service so I am certain it is a defect or misalignment of the screen.
Got my phone back from the service today. They said that the light bleed is normal and should be expected with "edge" screens. Yet as a precaution they swapped the screen again. Now I have to deliberately look to find the same problem, so on that behalf problem solved. What they didn't manage to fix is the uneven greens. The screen is quite uneven from top to bottom. Darker at the bottom, lighter at top. Really don't want to send this fixed again so I'm pretty sure I just try to live with it and see if it really bothers me with my normal usage, videos etc. I do know that this issue is really common with amoleds (speaking from experience.)

Thanks for your reply, I also have a suspicion that it might be due to the fact that I used navbar to make the navigation bar entirely black, making the navigation bar "not to burn in" so to say. I disabled that and will see if this has any effect. I also disabled the home button on AOD. If it is burn in it is extremely light still, and only visible with gray backgrounds. I have a feeling that it might be fading away, or my eyes are just starting to give up fingers-crossed, the latter probably the better since I hate to be this nitpicky.. :silly:

Um... That's exactly why it happened. You need to understand what "burn in" is. It's not burning at all. Simply that amoled pixels lose brightness and color the more time they are used. That's all. So if you have a status bar as black, it will not be losing its brightness but the rest of your screen will. So basically you burned in your screen. Really the screen is always burning in, the key is to make it burn in uniformly. That's why leaving AOD on without it moving would burn the time in, because the lit pixels are decaying while the rest of the screen isnt
