S8 Black Crush / Gradient Banding issue - Samsung Galaxy S8+ Questions & Answers

My S8 Plus is having Gradient Banding (Black crush) display issue. Darker areas looks pixelated & light grey look like greenish. There's no black crush during AOD screen.
I tired resetting the phone & flashing firmware again. Nothing changed. S9 had this same issue but a software update fixed it.
Let me know if anyone fixed this issue by downgrading or using a custom LOS rom

OnePlus display color temperature/white balance

Hi,
I want to get more cold color temperature. Also overall white balance - everything seems to be too warm and yellow. I can't change this using CM color Hue setting, because it doesn't change white balance, it only makes all colors to be weird. Also I found display when using revovery (for example , twrp), screen seems to be more cold color, no warm no yellow and they say Color OS has colder display too.
So it this some kernel related setting, etc? Some kind of hidden system configuration (build.prop or similar files)? How can I force colors to be colder, how can I change white balance. This is because that yellow colors are very annoying for me. Did you experienced the same?

Major Screen Problems

Hey guys I've noticed a screen problem with my Samsung Galaxy S6. On my phone I can only detect it when using a black background/any image that is black. So I was swiping through my homescreen, and noticed a a color shift that would cover the sides of the icons. As I swiped back and forth through the different screens. I figured it was maybe the launcher I was using(I'm using nova launcher prime beta). So I switched back to the regular Samsung launcher and experienced the same problem. It's not a big deal but I think I'm going to get it replaced.

Actually I think I have the same issue. It particularly shows when scrolling in apps with dark (black) elements which border to another dark - but not black - (e.g grey) element.
For example in the 'relay for reddit' app with the night OLED skin enabled. The usual list background is black, while already visited links have a greyish background. if you scroll through the list, you notice that color shifting. I just did a quick video to demonstrate the issue. It is very difficult to see there though .

Is that a singular issue which would be solved by a replacement or is it a general problem? As this issue only is visible when black pixels become lit I assume it is a general AMOLED issue :-/

Adaptive Display changing white points in different light.

Hey guys, I was using my phone browsing the web when suddenly the white point changed! The screen turned slightly purple and I think it is due to Samsung's adaptive display and my purple LIFX bulbs.
Here is a video link: https://www.youtube.com/watch?v=ujVIFA5LESQ
Any one notice this with their S6? Its running Marshmallow if you guys were wondering.
After seen your video , i tested , and with the purple color in the background , the white colour get a little bit darker , when u look in recent apps it becomes again white. tried with other colors and white didn`t changed.

It's a Chrome issue. I use Bromite, which is based on Chrome, and the issue started with the latest version.
It's quite irritating, but it will likely be fixed in the next update.
I too had the same issue. As someone mentioned in a different thread: disable wide color gamut in chrome flags. That fixed it for me.
Yeh, I to have seen this chrome tint issue...

Grey Color Issue with 90hz

Does anyone notice that the dark colors especially grey get significantly brighter when using 90hz compared to 60 hz. It's very annoying and can be seen when using the dark mode on WhatsApp or the dark mode of the phone and pulling down the notification shade. The greys become way too bright and the display seems washed out:crying:
Grey looks normal to me, Oxygen 11 has more grey element which i personally like
