Suddenly, my display colors shifted to a greenish tint and everything looks washed out and dull now. I did not drop my phone, the screen is not broken, and it still has the original screen, and the phone was never opened for any service. I dialed *#0*# and checked the green, blue, red colors and they looked normal and equally strong. This is clearly a software issue. The issue is less noticable on max brightness, but very noticable on low and medium brightness. Today, the screen colors randomly returned to normal but the screen started flickering. Any ideas?

Anyone notice a strange dynamic shimmering/interference effect on darker backgrounds at low to medium low? It's almost like the screen is picking up analog interference. I have not tried to capture on camera. Pull up a solid color (grey, like the google now background, or white) and set the brightness to min.
Anyone else's tab have it?

I have it on my current Galaxy Tab 7.7, it is very visible especially on backgrounds with gray color
On my previous Galaxy Tab 7.7 it does not have this problem
I have no shimmering or any other issues with my screen. It's perfect
Got lucky for once, hope it stays like this.

It primarily happens at minimum brightness, solid color (white screen)
Can anyone else check their tablet for this issue?
I think I have this issue, is it like a random slight colour variation every so often? I keep thinking I am tripping out
Sent from my GT-I9100 using xda premium
I have the same problem, on minimum brightness, mostly on grey colored areas on the screen.
the only time i see this is when their is some oil from skin on the screen. it looks rainbowy.
aboslutely nothing that looks like shimmering otherwise.

Tested it at night in the dark. Auto and minimum brightness. Solid red, green, blue, gray, black and white colors. No shimmering or any deformation on the screen.

Thanks for checking, guys.
My first P6800 from february this year has had this issue and I thought this is something oled specific. After my bag got stolen (lucky bastards) I was buying a new p6800 in august. These downtuned grey and green colours are now rock-solid on that new device. So obviously that is a little bit of gambling. quality control and yield of larger oled still seem to have potential...
Thread moved to Q & A section.
Got my OnePlus last night and generally I love it. But I have one showstopper that I'm hoping has a fix that I just don't know about. Is there something wrong with my phone, or is there a fix, or is the problem with me that I’ve become perverted by AMOLED?
See, I use my phone to read at night before bed. Lights totally off, and the black background is just not black, it's grey. My last two phones are a Galaxy S4 and Galaxy Nexus, both of which have AMOLED screens. From what I've read, the AMOLED has a very deep black because apparently the lighting is per-pixel, so the pixel is literally not even on when black is on the screen, right?
So when I read at night, the lit pixels are a deep amber orange, and the black pixels are...black. On the OnePlus, the deep amber orange is washed out (comparatively), and the black pixels are...grey. This is pretty much indistinguishable if there's any visible light in the room, but at night with all the lights off, it’s very obvious since I’m used to the AMOLED black. This shows up in both my ebook reader, Moon+, and in Chrome and Gallery when downloading a "pure black" photo. I even use a program, Screen Filter, to dim the screen down below the lowest brightness setting, but the black background is still too bright for me. And yes, it’s there without Screen Filter.
Again from my reading on this, I seem to find that LCD screens (which the OnePlus has) light the whole screen for their backlight, so this may be pretty much inevitable. Is this accurate?
I’d post a photo, but in the kind of low light conditions I’m talking about, no photo would show that kind of contrast. At least no photo I know how to take.
PS - This does not appear to be the "yellow screen" problem I've been reading about. The colors seem consistent from top to bottom. But I'm not very good at color distinguishing.
Any help is appreciated! Thanks!
You're just used to AMOLED displays, the blacks on those are much deeper because it's not actually lighting up when it's displaying black, it's displaying nothing at all. This is because there's no backlight, each pixel is made up of three LED's, so when it's displaying black none of those LED's are firing up. An LCD display is completely different, even when it isn't really displaying anything (black) it's being lit up by the backlight. There's nothing you can do about this.

What he said.... the OP can adjust his screen settings accordingly to emulate a "AMOLED" experience as previous phones such as N4,N5 has done this.
http://forum.xda-developers.com/showpost.php?p=54321008&postcount=6 try those settings it might satisfy the OP when it comes to blacks being blacks and not gray
I noticed that when I have Always On display at maximum brightness, the device turns on many random white pixels in the area that was supposed to be black, kind of simulating a LCD backlight.
It is noticeable by exposing the sleeping phone to a bright light so it will go to maximum brightness while Always On, then turning off the lights while the brightness is at maximum you can see the "backlight" (white pixels in the black area). As soon the phone adjusts the brightness you can't see it any more.
Here are some pictures, comparing maximum brightness, low brightness and also comparing to a S8.

Please note that by taking a picture makes it more evident, in reality it looks just like a LCD backlight, not a star constellation like in the picture. Even though it is not bad in reality I am concerned because this should not happen in a black screen in an OLED display right?
I tried replicating this with a regular image and I cannot, I can only see it while in Always On display.
Anyone else having similar issues with the regular Pixel 2? Or even in the 2 XL? I did not notice this happening when I had the 2 XL.
My blacks have always had that LCD type backlight look. I was wondering the same thing but I've seen others with it so I just assume it's the design. Not keen on it but it's not the end of the world for me
To me it only happens in always on display. If I have a black picture on my screen it doesn't show this "backlight"
I have been always using Night light before going to bed which makes the screen warmer. This is good for you before going to sleep, as blue light will disturb you. If you are new to this, search this topic up in the Internet.
So, recently I thought about using Reading mode (which converts the screen to greyscale) for night and what I found in the Internet is that this mode as well as Night light helps to fall asleep. However I was confused, as greyscale includes just shades of black and white, whereas white is the mix of red, green and BLUE. I conducted a little research using my phones and a macro lens.
I wanted to find out which colours are really being displayed when using Night light/Reading mode. I shot some macro photos of the OLED screen (OnePlus 7 Pro) and I did one shot of the LCD screen (Xperia S). Here are the results:

Night light:
#1 As you can see, on the first photo not only are red pixels involved in Night light but also the blue light is reduced.
#2 On the second image the difference is more subtle when the change concerns white light, however when taken as one the difference is noticable.
#3 On the third image there is the same story. The bluish colour is now dimmed and some more red is involved.
#4 Here I was viewing blue and red colour. After enabling Night light the blue colour dimished strongly and the red was even more punchy.
#5 This one is taken on the LCD screen - the same trend applies.
Reading mode:
#6 Here I was displaying pure red. After applying the filter, the screen turned into some shade of gray, which is the combination of red, green and blue. Thus, blue pixels got involved here.
#7 This is again a mix of red and blue. After using the filter, they turned to different shades of grey. So on the blue side the red pixels turned on, and on the red side the blue pixels turned on.
According to this, my guess is that Reading mode doesn't really help much when going to bed, as blue pixels are still turned on when viewing any colour (apart from black on OLED screens). What are your thoughts? Am I right or do I miss something?
I recently sent my phone back for a screen replacement. And the new screen is insanely greenish, not partially greenish, but greenish everywhere. After comparing it with other phones, I found that it was not a too-much-green problem, because the screen still looks off with green intensity reduced with Color Changer Pro. The problem is the screen's tint is off, which should be moved towards the megenta side.
And I saw that you get to manually control the tint on Xiaomi phones. There's no such thing on Samsung's One UI. I know you can control the color balance when you set your screen mode to Adaptive, but it's wayyy to saturated and like I said, reducing green intensity won't solve the problem.
So anyone got an idea about how I can change the tint of the screen? Thanks ahead.
