I was wondering if there was a way to adjust black level (contrast) on the g tab? There only seems to be brightness in settings. The blacks are a little washed out looking espcially since I went to a gingerbread. Any way we can manually set this up or is it something hardset in a driver? If there is acccess to RGB settings that would be a bonus. It would be nice to color calibrate the tablet for photo display.
thanks
Wondering the same
It looks like you cant put it brighter than the max it comes with
First off, grovelling apologies for what is probably a painfully newbie-ish question - I am entirely new to Android phones. I have tried searching - came across this thread, for example: http://forum.xda-developers.com/showthread.php?t=1124669 - but haven't found much in the way of practical solutions yet. This may conceivably be more of an "Android question" than a "Galaxy S2 question" as well, I'm not sure....
Anyway: one of things I use my phone for an awful lot is watching videos. What I'd like to be able to do is get the the display a little closer to a properly callibrated TV - so the whitepoint should be somewhere near D65, proper white balance across the whole grey-scale, the gamma somewhere near 2.2 across the scale, primary colours not too saturated, and so on.
The main problems at the moment seem to be that the white point is pushed quite badly towards the blue, and that the green primary colour is oversaturated (this is in line with the findings in the thread above). So my question is: what can one do about this?
I've investigated the "Display" settings menu, and discovered the "auto-adjust screen power" option which (again, according to the thread above) improves the gamma (reducing black-crush) at the cost of somewhat reducing maximum brightness. I've also spotted the "background effect" option; setting this to "Movie" makes colours a bit less over-saturated, but green saturation still isn't right. And within the standard video-playing application I've got the "colour balance" set to "Warm", which helps with the blue push a little, but not enough.
Are there any other display adjustment/callibration options that I've missed? Are there any apps which allow the display characteristics to be tweaked? And are there any 3rd-party video-playing apps which allow more precise callibration of the overall colour balance without compromising playback performance?
Both the INT version and Sprint's version have a setting called Background Setting in the display section of the phones setting. There is three settings Normal, Movie and Dynamic. I liked having the ability to switch the contrast and saturation pre-sets when I trialed the sprint version but cannot do this on the AT&T.
Is there any way to Mod this functionality back in?
Thank you
Actually its called "Screen mode" on the international version.
I like it cause photos look 100 times better when the saturation is set to movie mode.
I went to set this on my dad's new AT&T gs2 and it wasn't there.

Is this something that could be easily added back in? I have no idea why att would remove that functionality.
Hello,
I'm just looking for some real user feedback on the display quality, specifically the color temperature / accuracy. Detailed reviews posted outline indicate that the "white point" performance of the G5 is relatively poor, resulting in noticeable blue tint for white backgrounds.
1) I understand that there is some amount of screen adjustment provided by through accessibility settings. Can anyone confirm if this helps to reduce any blue tintedness or if there are other mechanisms to do so?
2) Can anyone just provide feedback on the screen performance in this regard?
Thanks.
I have the unlocked RS988 model, and yes the display is a bit "cool" for my liking. I installed Bluelight Filter and was able to use one of the color filters (brown) set to 8% which has helped.
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.
