hi s6 edge is my first amoled phone and i noticed that while using it i could see sometimes white lines on gray backgrounds and after few seconds they will slowly become gray. is this normal for amoled?
i tested it by using the amoled burn-in fixer and the black line in the pic after pressing hide ui become a light shade of gray then slowly become gray

Sounds like a hardware defect; however, the picture you shared looks like the black line is just a UI element of that particular app.
Could you share more pictures?

yes it's part of the app but if i hide ui the screen becomes all gray but the black line a leaves white or lighter shade of gray line that slowly disappear after few seconds.
this happens even while browsing the internet and using apps white or light gray shades lines appear in other parts of the screen if i suddenly change the background to gray like my home screen.
it's like the pixels are delayed when changing from dark black colors to gray. now i changed my wallpaper to default so i don't notice it.
i tried to take pictures but i's not noticeable, my old phone camera it's not good.

Please look at the picture http://img51.imageshack.us/img51/3360/img4165kv.jpg.
It shows my desktop wallpaper on SGS1 on the left and SGS2 on the right. The top left part of the wallpaper looks fine on SGS1 but it turns ugly dark green on SGS2. Please notice that the other colors (pink, light green etc) look very similar on both devices. I set the brightness on both devices on equal level. My SGS2's screen displays like this only dark colours, bright colours are fine. Similar thing happens in AOSP/CM9/10 settings panel to dark grey gradients - it turns kinda dark green and ugly.
Here's another example: http://img23.imageshack.us/img23/4066/img4166a.jpg. AnTuTu background on the SGS1 (left) doesn't look so dark.
Am I the only one experiencing the issue? Do your devices display equally bad dark colours as mine? Could you post photos of your CM9/10 settings panel or AnTuTu's main screen?
I am kind of just curious about this, as I have searched the net and have found no one who has experienced the same problem.
I have a Blu Touch Book 7.0 plus, and plan on making do with it until the right phablet comes along at the right price. About a week ago I had it in my pocket as I helped to unload some heavier packages from a truck. It took some impact while in my pocket, I didn't think it took any meaningful impact. But then I turned on the screen, and everything seemed to have a blue tint. On closer examination - it didn't have a blue tint per se, but black was being displayed as blue; opaque black was opaque blue, semi-transparent blacks and darker grays and what not resulted in a blue tint. But whites and most colors displayed perfectly fine - i.e. for example, the Google home page looked completely normal. The display damage is evident even on boot, as soon as the manufacturer logo pops up before the bootanimation.
My workaround for the time being is to use a screen filter that places a semi-transparent white image over the screen, which gets rid of any hints of opaque black with about 48% transparency. It results in faint colors of course, but the colors are at least accurate with no blue tint, and the screen looks almost completely normal from the certain viewing anglea. Interestingly - the absence of opaque black seems to result in a lighter load for either the cpu or the gpu; previously the phone ran very smooth but if I had Dolphin (or another resource consuming app) open, and turned the screen off without pulling up my home page first, the screen would not always turn back on right away, either I would have to long press the power button or wait up to several seconds. Now, regardless of what I have open, I can toggle the screen on and off without lag.
So is this damage to the gpu? The screen itself? Does anybody suggest a better work-around?
Appreciate it.
Are you noticing that when you use Stock Gallery, Netflix, and YouTube apps, rendering a completely black picture or video doesn't show pure black. Rather it looks like a blotchy black. It bother me so much since this is an AMOLED screen and I know that when an OLED panel renders black it shuts off every pixel rendering black so a plain black image should turn off the screen completely. But in my case I see blotchy black screen and this is only noticeable when you're in a dark room. Please tell me you also experience this. Otherwise, can somebody explain why? Do I have a defective screen? Thanks!
Videos and pictures in lossy formats won't have a perfect color information, the system will try to interpret it the betst as it can, mostly resulting in the screen showing strange patterns instead of a plain black picture.
This app will create a lossless black picture, you shouldn't see any difference between screen on of off.

I don't see any light bleed for that. However, it's just weird because when I did a screenshot and open it on my stock gallery app, it again showed a blotchy black. But when I open in Google Photos, it is completely black. Also, watching this completely black video in YouTube also shows blotchy black. https://youtu.be/XIMLoLxmTDw
screen replacement

I don't think this is a screen issue. I've used Mate 10 pro for 2 months and haven't come across any issue. And I found the mate 10 pro screen is very solid. If you want to replace it, that would be very difficult.

Did you try it at minimum brightness in a dark room?
Edit:
I mean maximum brightness in a complete dark environment.
So is it pretty obvious , or does ghosting usually happens on low brightness on every AMOLED display or is this phone only suffering from this ?
(I saw ghosting while I was horizontally scrolling a black picture of a gray background).
Can anyone confirm this for me ? ( Not a huge issue though , it doesn't happen after the brightness is increased)
Try with this image in lowest brightness
Zoom in and move it left and right you will see a trail of weird color trailing the black circle.
its normal for amoled displays
almost all amoled screen leave purple trails when switching from pitch black to some other color pixels.. don't worry about it
Ya when scrolling in app drawer the icons looks like wobbling.
Yes this has been the case in my Realme XT as well. When you have black background in the app drawer and there is any app icon that is dark you see the icons changing their shape while we scroll.
Even in YouTube when you turn on the Dark Mode and there is any video that is pitch black you may see it leaving a trail when you scroll through the feed. This is more often when screen is in low brightness. Is this issue for all other phones with Amoled panel or only with Realme XT ?
Amoled panels basically has the lowest response time in any display technology format except "Ink Display". Every individual pixel lights up individually from switch off (black) to on (any color). Higher the brightness means higher the color spectrum shining into your eyes and thus it let you see no ghosting while at peak brightness. It's still happening but we dont usually see that clearly. Ghosting is very natural phenomenon of Amoled technology. Also these budget Amoled panel tends to big fan of burn out. So make sure you are using live wallpaper that changes or moves (stock one that comes with the ColorOS is good enough).
Hello. I have a question regarding the display of dark grey at low brightness. Noticed this using the google web page in dark mode before going to sleep with all other lights dimmed or off.
I also noticed some burnt in segments of the screen like nav bar and status bar at the conditions described above.
I am attaching the dark grey filled image I use to distinguish the problem. Can you please test it with your S21 in dark conditions and fullscreen and tell me if you see same noise and smudge-like artifacts?
I must say I tried to go to BestBuy and Target to compare it to other S21 by myself, but obviously it didn't work because there are too many light sources in the store and it's too bright to see that.
I also tried to make a photo of what I am seeing in completely dark room, but obviously it's less informative compared to human eye.
Thank you.

Maybe I am not very discerning but screenshot_* shows no anomalies on my S21. The file_000 however does have a visual imperfection. It's the file itself and not the screen because the "smudgy" area moves as I scroll and grows when I zoom. So it's an artifact of the file. It does have some subtle grey coloring.

The File_000 has anomalies because it's a photo of a screen producing artifacts, when the Screenshot is just filled grey and should be clean of any artifacts on a healthy screen. I must say when I open the Screenshot using gallery and in fullscreen, and try to move it left or right until previous or next image border shows in the gallery, I can see the artifacts and smudges remain static because it's screen defect but the image (screenshot) is clear of any imperfections. Thank you for trying though.
It is normal since a few years, Xiaomi since the Mi 8 and has it Oneplus since the 8 series and now Samsung.
It has something to do with the newer generation panels.
