I have noticed another HORRIBLE crap with my screen - I can see how white|gray color suddenly changes a bit to green.... and back again to gray|white. Seems like a controller keeps changing white balance or gray point cyclically. It is mostly seen when you pull down notification panel and look at it for a minute. The pattern of tint change from green to gray goes like for a 5 seconds each 5-10 seconds. And it is noticeable. Especially when you read the web page that is evenly lit with the light color. It distracts a lot from reading... Like your eyes suddenly find an obstacle and jump over it and all because of slight change in gray point tint.
Does anybody see the same gray|white point floating?

I would be happy if it were so simple... I tried everything before posting here (auto adjust, auto brightness, different levels of brightness) - the problem persists.
Hello everybody, I have the following "visual effect". It happens roughly 50% of the times the display switches off. It doesn't matter if it is by it self, by the power button or by a software button. In the very moment when the display switches off, a greenish dot in the center of the display flicks for a split second, along with a same color vertical line trough the whole screen. Obviously it is not supposed to be this way Beside this issue, there is no other problems with the display or the phone( for now). What do you think about this? Thanks in advance
Sounds like a screen off CRT effect, check you tube to see if that is your problem
Isn't the CRT effect a horizontal white line ending up in a dot?
I genuinely think the OP's screen may be defective...
Sent from my GT-N7000 using xda app-developers app
do a lcd test and check if all pixels are working ok
Unfortunately it is not a CRT effect, although it looks a bit like it. The difference is, that the line and the dot( little spot) appear simultaneously for a fraction of a second. In a daylight it is hard to see it, even more it happens just 50% of the times, but not every other time. Its somewhat random.
The *#0*# test do not show much. No dead pixels. On blue you cant see anything, on green and red I think I see a little bit darker spot in the center of the screen( where the dot/spot appears), but there are such darker sports and elsewhere on the screen.
BTW, I noticed recently, that when the screens dims a bit shortly before switching off, this dimming happens not so smooth. How should I say it... it happens on a several steps, although the whole thing is done in less then a second, it is not so fluid. Is it supposed to be this way?
Thanks for your help guys
have u tried flashing a different rom stock
I am on the latest German stock 4.0.4, tried several others, including 2.3.6. .Currently with Hydra kernel. No difference whatsoever. I think the auto-brightness doesnt work so good. When set on fixed value it dims more fluidly.
if u on stock rom and not rooted then take it to a service center
Is anyone having any trouble with setting screen mode to vivid?
When I switch to vivid, the entire screen becomes very orange, to a degree that something is clearly wrong. It looks like the blue light filter is turned on, even though it isn't. And turning on the blue light filter makes it much worse. It's like there is a single application of blue light filter permanently active, and then a full second layer being added when actually turning the blue light filter on.
This is coming from someone who generally runs Warm1 or Warm2 settings on my TVs and monitors. This isn't just a warm white, this is distinctly orange. Changing back to natural brings the white levels back to a normal level that I would say is pretty neutral, if not slightly warm.
When set to vivid, changing the white balance between warm and cool does almost nothing; the change is so subtle that you have to actually flip back and forth several times to notice it. And changing the RGB in advanced settings does absolutely nothing.
A couple other facts to note:
- I do not have any type of screen protector; the one that was on the phone out-of-the-box has been removed.
- This isn't just related to the angle at which I am viewing the phone; it is consistently orange from every possible angle.
- Blue light filter, night mode, and adaptive brightness are all turned off.
Is anyone else experiencing this, or is it just on my end? I have restarted the phone several times. I would really like to avoid a factory reset if possible.
i find mine to be more warm in natural mode however is been known that the screens on the S10 are much warmer than s9/n9 due to the reduction in blue light
if in vivid mode - please access the manual setup maybe the red is setup to max or something
Check that you do not have night light also selected in the drop down settings, as the s10 already has blue light filter reduction.
Mine was like that originally. Had to install Play Books and then turn off it's version of night mode. Seems that even though I didn't install it on this phone, it's night mode somehow still carried over.

As I said in my post, it doesn't matter what I set the RGB values to, they make no difference. And the whites look just fine in Natural mode, so it's not the screen, it's a software issue.

As I already said in my post, the blue light filter is turned off. It's off in the quick settings and off in the actual settings. I can turn it on and it doubles the problem; turning it back off returns to the normal problem.

I've never used Play Books before. Installed it just now and there's no night mode in it.
So it looks like the bug is tied to setting a schedule for the blue light filter. This morning the overly orange effect was gone. It seems likely that the setting somehow carried over from my previous phone and stayed separate from the one on this phone. Unfortunately, this probably means I will need to factory reset because there is no way of accessing this second schedule.
I won't be the only person that has carried over data from a previous phone and used a scheduled blue light filter. I hope Samsung fixes this in an update so that others don't have to deal with it.
In Play Books, open any free book and click on
then disable the schedule and hit turn it off now if it's on
Edit: screenshots aren't showing up for some reason. Anyway open any free book, tap in the middle of the page to bring up the menu bar at the top, tap on "Aa" and then night light settings. Set the schedule to "None" and hit end now if your screen is currently orange.
My wife has never installed Play Books, and that still fixed it for her.

Good to know, thanks. If the issue comes back again tonight, I will try this.
I think there is some hidden night mode in android which Play Books ties into. My wife's old Pixel had a night mode setting in the settings app which she had set up, and the new S10 night mode looks entirely different. Think copying settings and accounts over brought the hidden night mode settings over, and Play Books is just the easiest way to access that hidden setting.
The Play Books trick worked. Thanks guys!
Exactly like @lightmastertech said, the vanilla Android night mode settings are hidden but still active, and it carried over from my Pixel 3. Play Books allowed me to access this menu (odd that it's still there, 100% intact) and disable it.

Google's gonna get a lot of downloads for Play Books now, lol. Only app I could find that accessed the system night mode an not its own filter overlay. Glad it worked for you man! ?

I have a s10+ and just noticed I have the same exact issue. I posted earlier on the s10+ forums.. Natural looks much cooler
Nevermind.. the playbook trick worked. I came from a pixel and had the blue light setting turned on much earlier than my s10+. Thanks @lightmastertech @Sevael
Wow, just wow. Ran into this tonight for the first time because I wanted to try out the Vivid colour mode. What an amateur oversight by Samsung to not prevent the stock night mode from running. For those that want to have access to this setting without Play Books, you can use Quick Shortcut Maker and just search for Night Light, then launch the returned result. It will put you right into the stock Night Light mode.

Can you now change the color temperature after play book trick? I cannot still change it.
I just had to bump this because of the absolute cavalcade of potential issues that can cause the screen to appear tinted. I've googled this for almost a year now after only noticing the yellowing of my screen when in Google photos. Then the random tinting was happening at sunset and every forum pointed to blue light, vivid setting, night modes etc... To find this elusive setting in play books of all places, to fix an issue that's plagued me through my last 3 devices, to the note 10 I'm on now, and it's finally fixed. Thanks. Thanks a lot.
I have only just bought an S10, and I have the same issue as OP. I have installed play books and followed instructions on this thread, but can't find in on play books night light settings set the "schedule" to "none" and hit end now.
Thank you so much ! Same happened to my FOLD - You solved it for me !

You are a genius - I had this happen to my new Galaxy Fold - it suddenly became warm and dim and I couldnt figure out what happened - Searched forums and found your solution - This must be pinned in all SAMSUNG forums
Thanks !

Did you find out the solution?
My note 8 is 1 and half years old now. about 2 month ago, it start to have an issue that the screen will become yellow and blurred if turn off the screen and turn on again within 5 seconds. when the screen become yellow, the brightness of the screen will drop, also the text on the screen feels like got a shadow effect. Not related to night mode/blue light filter/google book night mode etc, all tested on/off and no use. and recent month it become even worse, when the phone become hot it will also become dim and yellow. any solutions?
the dim and yellow effect even visible when the phone restart and show the SAMSUNG boot animation. when dial *#0*#, check the color, red looks like orange, green is ok, blue looks like purple...

You need a new screen unfortunately. That's not going to go away it's going to get worse.

I agree! Sounds like the display has developed an issue.
well, it seems so, have to replace the display. but the display actually can show the colors well -- when it's cool, and when you press button to activate the screen after the screen had been off for at least 5 seconds.
if there can be a software solution, disable the dim color mask when the phone is hot, then I can save the money for replace the screen...
After lots of research, I finally found a solution, but its temporary.
Download & Install ScreenDimmer (Dims Notification Too) By Etsang From Play Store.
Keep the auto brightness off, and device brightness @100% (Or Above 50%), install app, give permissions and change brightness from app according to your usage, thats it.
I think red tint is a software bug, not a hardware, because at last the motive is to decrease the brightness (dim the display) without red tint. App is also doing the same. The only difference is it has no red tint.
This works but if advise against using it. It records your inputs.
More to your point of it being a software bug, I agree. I wats always under the impression that they could fix it by adding blue in software based on the light sensor input. I noticed that if you put your phone in grey scale (in notification tray) that the grey for the icons in the tray that are toggled on, are actually grey while the other have a red tint. Normally the toggled on icons are blue when not in grey scale. The fact that it can show grey properly under these conditions as well as the one you described shows software could address the issue.

Oh wow it works but im gonna wait for asus to fix it.
Yeah, actually the brightness mechanism of oleds and LCDs is different, lcds just have a backlight led that would get brighter or dimmer pretty straightforward, but OLED's case is different, getting brighter or dimmer means showing different frequencies of the same color so our eyes can see that color brighter or dimmer, thats why when you turn the brightness of an oled panel down you still dont feel the way you do with a lcd
Long story short, this tint issue is most probably caused by wrong calibration of different brightness levels but still, i would take my hopes up with asus...they dont have a good history of customer support at least in their mobile phones section
Btw, thanks for the app and thumbs up
happy to hear this is a software issue. I am sure Asus will fix this with an update.
I knew this was a software bug long time ago. Since I noticed even night mode did same problem too. That's who I found out this is software defently.
