Samsung device screen mode option not working after screen replacement - Android Q&A, Help & Troubleshooting

After replacing the screen for my galaxy j7 pro, all options relating to changing the display color are not working anymore. This includes Screen mode, Blue light filter, color adjustment, etc,... The guy who replaced the screen said it wasn't the original screen, so those settings wouldn't work. Is there any software or hardwave trick to fix this. The default screen mode on my phone was too saturated and blueish, rendering the purple color to blue, and that's annoying.
My phone is galaxy j7 pro j730g/ds (vietnam) and running official one ui rom

How to change color temp

Hi, yesterday I bought a S2. It's all ok but the screen... The white color, if I watch directly, seems a bit yellow (entire), on the S1 it's white! If I tilt up or down it finally shows white. I think the cause is the color temperature, on S2 it's warmer and on S1 it's colder. Is there a kernel or rom that can give you the possibility to change temp settings? I've tried to set brightness and background effect, it's still yellow.

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)
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.

Blue light Filter problem with apps on playstore

Hi ,
I have noticed a problem in blue light filter in apps available in market.
They ask for permission for drawing over apps. And the effect they produce is not similar to reducing blue color but putting a yellow/brownish layer, which makes black look brownish. When compared to the bluelight filter option given in the ROM itself , there is noticeable difference. The color doesnot look washed out. Black is still black. And the sharpness is maintained. Only thing is it lowers blue light emission from screen.
I have Samsung Galaxy Note 4 with Marshmallow and it doesnot have inbuilt bluelight filter. I want to stay with same ROM but am ready to root device if some application can actually modify contrast. I have heard that screen resolution can be modified with adb so i am ready to experiment color correction through that as well.
Hoping for a early reply,
Thanks

Galaxy Tab S7 Plus green tint display issues at low brightness

https://www.reddit.com/r/GalaxyTab/comments/idqrip/s7_display_issues_at_low_brightness/
I have same problem with my Galaxy Tab S7 Plus 5G at low brightnes - with dark mode grey colour looks greeen
Very bad for such expensive device
Leave the brightness up and use a screen dimming app, if the dark overlay on the screen is fine and does not show a green tint the problem might not be the screen itself and should hopefully be solvable with a software update.
This seem to be a common problem of (Samsung) (AM)OLEDS. I had to get three Tab S5e refunded because of this green tint and other low light problems.

samsung s9+ screen brightness

My s9+ screen suddenly had a lines and yellow color all over the screen and if i move the brightness bar down to 90% it get off lights.
When i play video or be under the sunlight It works fine without yellow color or lines

Is that applicable with any workaround solution ?
