Hi guys, I am having a problem with my Galaxy S9 Plus. When I open a PDF in Night mode, while scrolling there is some deformation on the screen - in the video (link shared below), there is a grey frame which deforms and 'shrinks' while scrolling up and down in the PDF.
I've explained the issue properly in the video (jump to 0:27 in the video) whose link is given below. Kindly help me out in solving this issue as soon as possible and please check if this issue affects your device or not. Thanks.

Mine is the same; I think it's normal AMOLED behavior: https://forum.xda-developers.com/pixel-2-xl/help/lagging-black-pixels-scrolling-dim-t3696188
My guess is that it takes longer for a completely black pixel to turn on than for lit pixels to turn off or change their brightness.

And I don't need to 'dim' the lights to reproduce the issue, as it is mentioned in the link you've shown. It feels really strange and unexpected from an expensive device like the S9+.
EDIT: To be more precise, the grey frame deforms and SHRINKS in size while scrolling.

Every Samsung Phone with Amoled screen has the this same issue! Nothing new!

I have a Samsung Galaxy Tab S3 and it's great but I can't figure one thing out. Which is the screens contrast. Dark scenes in Netflix or VLC player are too dark and hard to see. I tried different brightness settings, with/without blue light filter and the other color correction option for cinematic mode but nothing really works properly.
Is this an issue with the tablet or is there another setting to change the contrast or something?

I also noticed this with Netflix. Was hoping that turning up the brightness would help but it doesn't.
YES, YES, YES, I am shocked this isn't widely reported, I couldn't find almost anything about it and I've been searching for quite a while.
First of all it is really crazy that popular apps like plex or netflix don't offer any capability to change the brightness of the video played. No, we don't change the colorspace, black levels, bla bla bla.
I DID find eventually a solution (the ONLY one that works, a bit clumsy as it is): http://phandroid.com/2016/03/22/twilight-app-reduces-dark-contrast-on-samsung-galaxy-s7/ (yes, it's for the S7 and yes I did notice there the same issue, which makes it even crazier that it isn't something widely known and fixed).
I just picked up an S3 last night and I'm having this same issue. I watched the opening scene of The Defenders on Netflix, and I could hardly tell what was going on. Rewatched it on a proper display, and you're clearly upposed to tell it's Danny Randy much earlier in the scene, but I had no idea in the S3 until a blue light was clearly shining on him from above.
I used Twilight on my Nexus 7 because it lacked a night vision mode, ala blue light filter on the S3. I'm not sure how that can really help. Surely other people have found more elegant solutions to this problem? I've opened up other media files and they're all simply too dark. I get it's an HDR screen, but surely it has a mode for non-HDR content!
Do oled display have a blue light problem, I though it was only really a led thing.
John.
Might be an inconsistency with the displays. I have no problem with mine. Not getting any lag either but running a heavy debloated rom also. Battery life could be better. It's stupid you can't turn off the Wacom digitizer when s pen not in use. On my note 4 when I lost my s pen battery life was terrible because the Wacom digitizer stayed on. Should be an option in settings to turn it off. If anyone knows how please let me know. I don't use the s pen very often.

Try switching from "adaptive display" to "oled cinema".

Switching to modes other than Adaptive Display just gives me seemingly the same shade of yellow....
I have tab s2 and you can't change adaptive display. I wouldn't have bought this tablet if I'd known about this issue. Very annoyed.
I actually have the issue on my Samsung Tab S2, that the colors are really "hard" and lots of color information are missing in the video, details are lost in dark areas. Is there some fix for this or is the screen just too bad on the Tab S2? I know the Tab S3 has a HDR screen, and the S2 not. I dont have any HDR screens actually, but I can put color range to "full" on my desktop PC, which will en-light colors a bit, making details more pop out in dark areas (though black isnt fully black anymore if so).
Any color profile other than basic is mostly unusable, too much saturation. Still dark areas lack lots of information. Is there no way to fix this? I tested this actually
https://phandroid.s3.amazonaws.com/wp-content/uploads/2016/03/Screenshot_20160321-154452-400x711.png
and it helps with the details in dark areas, but it also makes the black bars of movies in Netflix and video players not black anymore but gray.
So from what i can tell, it's only a stock rom problem. As the screen looks amazing running liniage (best screen in the house). But I've recently decided to go back to stock debloated, as I think its running a bit snappier than liniage 16 or 17.
Has anyone found a black level fix for stock yet? (preferably not a screen tint app)
Touch the left hand side of the screen when watching netlix and a brightness slider appears

:cyclops: It's beyond what you're suggesting which is known :cyclops: but thanks for it
EDIT: I have now found a full workaround. First you need to enable Blue Light Filter. Then go to Settings > Accessibility > Visibility enhancements > Color adjustment > Personalized color, and choose all the colors in the correct order. If you do it correctly there won't be any change to the colors and Blue Light Filter will be "on", but actually not, which will override whatever Android is doing that's making the dark parts of movies way darker than they should be. So far I haven't found any cons of this workaround.
Original post:
Sorry to resurrect an old thread, but after trying to fix this problem for like half a day (lol) I think I found the best workaround so far. If you turn on Blue Light Filter and set its opacity to minimum, the filter will be barely noticable, but the brightness issue will be fixed.
One thing I noticed is that not all apps have this problem. For example VLC, Youtube do have it (you can even see the transition of colors and brightness for a second when exiting to desktop view). However Youtube Vanced doesn't have this issue, so I asssume the operating system does this dumb change of colors when it sees certain parameters in an app (maybe something in the manifest.json file?). It would be awesome if some more knowledgeable people could look into this issue, maybe they could find something about why YT Vanced has normal colors.
Has someone experienced "dancing blacks" with vertical or horizontal scrolling, specially in low bright settings?.(40 or below)
I have purchased an EU ver. Of V30 and i experience this behaviour every time i do scrolling with photos, desktop icons with black contour (like netflix) webpages with black línes or blocks... Or everything containing black colour.
When i move the photo, scroll across website... The part that contains black colour seems to dance on screen, it's hard to describe but it's something like jelly effect, the black part of the object, photo... seems slower and doesn't scroll accordingly. I went to a local store to check it on another unit and discard a faulty one and i saw the same effect.
Regards
That's the feature of all oled displays, nothing you can do with it except changing the brightness to the level it doesn't show any signs of this "violet trails"
i have that behavior too on my H930DS. no solution yet.
The phone regulates it's brightness through PWM, so that you don't have the same issue like on the g flex where the whole display got blurry and grayish when you turned the brightness down. Because the display shuts itself on and off many times per second (222 times according to a German review page), you see that when you are sensitive. Just set the display brightness higher, then you should be fine.
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

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.
Hi all, I've had my Mate 20 Pro for a few months now and I've slowly started noticing this weird sort of bleeding that seems to happen on my screen when I'm scrolling or switching between apps, particularly noticeable with apps that have dark mode on.
For an even longer time I've noticed that when on the official Reddit app (dark mode) for example and I'm scrolling down, the text becomes very fuzzy looking and the top of the text looks darker than the rest (or bottom if scrolling up).
Now the same thing is happening to images and app screenshot when switching between apps. It's become very noticeable now. Has anyone else experienced this?
I should note that this is on the lowest brightness settings. When I turn my brightness all the way up, I can't seem to notice it as much. My eye will only catch a split second of bleeding when scrolling past images.
I've attached a screen recording here gfycat . com/happyunhealthybeardedcollie but I'm unsure if you will able to see it or not. (I'm unable to post outside links or upload as I am a new user, apologies for the inconvenience).
Thanks.
Pretty sure it's OLED smearing

... and it is normal on this type of screens. Black color on these screens means powered off pixels. The time needed for these pixels to turn on or turn off during scrolling yields that smearing effect. This is the price we are paying for having screens that display black as it should be, i.e. total absolut black.
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.
