Screen Problem with Blacks - Samsung Galaxy S9+ Questions & Answers

Guys I'm having an issue during video playback. When there is a dark scene the blacks of the display are so deep they're crushing the details of the scene and the picture looks almost like a pastel drawing. There is also severe colour banding in dark scenes.
This happens on Netflix, YouTube, native video app, etc.
I've tried changing the colour modes to no avail. It also happens regardless of brightness settings.
I didn't have this issue on my S8.
Anyone else having this problem? I'm wondering if it's a hardware problem or codec issue.

video playback too dark and oversaturated

Hey
Ive compared video playback of the s3 with my gnexus and it was really bad.
The whole video was oversaturated and too dark. In the dark areas there is no detail.
The display mode and videomode configurations are complete crap and made things even worse.
Everything else of my galaxy s3 seems good. So i dont know if its a general problem or just my s3.
Hope someone can help me fix this.

Change screen mode in settings / display. Maybe try natural.
Brightness for the video player is managed inside the video app. While the video is playing hit menu then scroll down to settings and adjust brightness there.

Adjust the brightness within this video itself solve the problem.

Yes like in the video but the gakaxy nexus dont has this problem. And the gnex has also an amoled hd.
Making the brightness higher just helps a little bit and the warm cold or video mode natural mode configurations are awful.
And the biggest problem is that dark areas of the video are just plain black with no detail. Brightness can be fixesd by adjusting it manually.
I think its an calibration problem but i dont know how to do it. -.-
Is the video in 720p? Everything I watch in 720 looks perfect

Blotched video playback

I am sorry if this issue has been answered.
Whenever i try to watch a video on my S6 Edge which contains some grey or dark scenes, several blotches are formed on the grey or black colours making the video really annoying.
I use my phone for a lot of video playback and this issue has been persisted ever since.
If anyone has a solution to this please guide me
Thank you.

Dark scenes difficult too see in movies

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)

: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.

Hdr issue?

On S9+ exynos while i play the hdr videos on native player, youtube and even on mx player the colors don't really look that punchy to me and the whole screen switches to basic color mode when the video is played.
My screen mode is on adaptive display the resolution is set to wqhd+ and video enhancer is on
Anyone else having this issue ?
Yes. Almost the same here. Except mine flickers on and off randomly or when I bring up YouTube UI.

Have you tried playing the video with native or mx player?
Got two units one S9 and one s9+ both Qualcomm devices and both preform the same as you state, like yellowish tint or washed colors (only on HDR videos no matter what I used Netflix or youtube), I compared with my S8 and it looks stunning I think this is a software issue and Samsung should be aware of this

Contrast and screen brightness changed in direct sunlight

Hey, guys! I observed today that something funky was happening with the contrast and colors on my Pocophone screen. The black/dark background in apps like Youtube and XDA, both with dark themes and black or dark grey backgrounds, was getting light grey. Also, the contrast of the text seemed to change.These things happen when the top of the phone enters in direct contact with sunlight. If I cover the sensor with my finger, the screen gets back to normal. It appears to me to be an option to make text and content more visible in direct sunlight. Have you observed the same thing on your phones. What's your opinion? I'm using miui 10 Global Beta. Thanks

I noticed too. Seems a display feature
Neither this is bug nor faulty screen. That's because of Auto Contrast in display setting. Anyways you can change it.
yep, it's a feature... use standard contrast
Happens even when set to standard contrast. Cant seem to be able to fix it!
Set it to increased contrast, it solved the issue for me
