Screen is not white. - Samsung Galaxy Note 10+ Questions & Answers

I have my note 10 next to my note 8 and the 10 screen is not very white compared to my N8.
Anyone else notice or know how to fix it?

Make sure the blue light filter isn't on

Could be the blue light filter or screen temperature and/or screen mode.

Go under Display then Screen Mode and change it from Natural to Vivid. That should brighten your whites a lot more.

My blue light filter is off. But for some reason while using Vivid screen mode, the screen becomes more and more yellow after 6PM. On natural this doesn't happen.
Has any one observed this strange behaviour?

You have your blue light filter set from Sunset to Sunrise

It's the panel it seems Samsung have adopted a less whiter or warmer(?) one this time round, as all note 10 pluses I've held mine next to at stores etc are the same. My one plus 7 Pro is considerably whiter...

It's not a bad thing, I can assure you most Note 10/10+ have different screen calibration.
I have 3 S10 5G and the white looks different on all of them, lol. As a matter of fact even the native ONE UI dark mode looks different on all 3 units as well

This is clearly not a calibration issue. As I said this happens only in the evening time as if blue filter kicks in eventhough the filter is off. During day time the screen is white as usual.

Mine gets warmer when I go into Moon Reader Pro., its nice and cool white everywhere else on the phone And before anyone asks, yes BOTH blue light filters in the phone settings AND the moon reader settings are OFF.
I read somewhere that some people fixed it by going into Google books and apparently the blue light filter is turned on there and affects other apps. Dunno how much thats helpful since I didn't have G Books installed and when I did install it, the option was off but oh well

Checked that too. It is off there as well...

Hi there,
I was also wondering if there is another way (than the native tool) to adjust color temperature to set perfect white

Settings» Display»screen mode» vivd» move slider a little bit to the cooler side. Then go to advanced settings: turn down red, set green to about half and leave blue at full. Or adjust to your liking.
I've been making these adjustments since the note 8 but the note 10 seems more on the red side than normal.

Just did a factory reset, and this issue is gone. Probably something wierd happened while restoring from Note 9 backup.
Sent from my GM1917 using Tapatalk

I had this issue too, at 8:30pm, and it affected Google Photos and Samsung Gallery.
I had a OnePlus3 and had the bluelight filter set to 8:30pm.
My fix was to go into Google Books, open a book, click on Aa and turn off the filter. I never use Play Books, so it was very perplexing.
Therefore, I'm convinced this is a hidden Android system setting that is no longer accessible and carried over from the Android restore process. I'm happy to be rid of the problem though.

It is a well known fact that restoring from an older or former device often results in certain conflicts, as the settings and other componets are different between devices, this I've heard since my note 3 days

Screen Brightness Dynamically changes...

Hey everyone,
I've been playing around with my new phone for a few hours now.
So far, I love it!
However, I have noticed a strange bug. The browser seems to be dimming webpages.
To see what I'm talking about:
1) Open google.com
2) open the tab viewer
3) click on the google tab - it expands to fill the screen
4) as soon as it fills the screen, the page immediately 'dims'
As it is filling the screen, the background appears nice and white. However, once it completely fills the screen, the background immediately dims to a darker white...
VIDEO
Google Bug Report
https://code.google.com/p/android/issues/detail?id=23765#c0
OK, this isn't just limited to the browser. It happens on pretty much every app with a white splash screen. I.e. opening Facebook. The splash screen is nice and white, but when the content loads, the white background becomes dimmer and more gray...
Does anyone else know what I am talking about? I'm on 4.0.1 if that matters.

The phone dims purposely. I. Don't know if there is a setting to stop it though. I believe it is powersaving feature. Touching your screen resets the time for dimming and screen off though.

I'm not talking about the 'about to go to sleep' dim. This is a very slight, almost unnoticeable, dim when the white animation completes. For example, say I open an app that has a white splash screen and a white background. The app opens with the very white splash scree, then as soon as the content loads, the very white background 'changes' to a more 'off-white' or 'gray' color...
Can others please chime in? I really want to look into this bug, but I need to know if it is limited to me.
This is crazy now. Open google.com on the browser. Then tap the search bar (on the webpage) to bring up the keyboard. The white background of google.com becomes whiter when the keyboard opens. Close the keyboard with the back button, and the background becomes dimmer again.
Even the status bar partakes in this "dimming" action, so it is not limited to the web page.
WTF?
I see this too, it looks like it is caused by dynamic contrast adjusting the contrast based on the picture.

Thanks for your reply!
Anyway to keep the contrast the way it is when the keyboard is open? The whites look so much better that way...
I noticed this on my old Droid Charge as well. Maybe it's a Super AMOLED thing?

I'm not sure... Contrast is pretty bad when the screen is predominantly white. However, as soon as some darker colors are introduced (menu/keyboard), the whites brighten up and contrast improves.
Could this be because the all white screen draws more power than a screen that is only partially white?
Go to a mostly white screen (i.e. Google.com) and slowly pull down the notification bar. You will see that the white of the webpages gradually becomes brighter... This is really bizarre...
Good way to test is type in about:blank into the browsers address bar for a full white page.
My gnex does it as well I've never noticed it before but now I can see it its going to annoy me

It originally annoyed me. However, I probably will get used to it in a couple of days.
I was originally worried that it was just my phone doing this (due to the lack of replies on this thread). However, now that is seems like this occurs on all GNs, I'm pretty relieved
Whatever, this screen is gorgeous when displaying colors. Black-on-white contrast could be better (i.e. black text on an all-white webpage), but it is good enough...
I'm still wondering if it is hardware or software that is causing this. If it was software, I would definitely like the higher contrast white all the time...
Mine also does this D:

I think the galaxy s2 and other Samsungs like the note do this, but it is by design from the setting which can be turned off. It supposedly is for power saving of bright colors.
My question is any GSM nexus user seeing this? Cause I attempted the steps in this thread in a dark room and dinr notice any issue whatsoever. Is this a Verizon version issue where maybe all lte versions have this enabled to conserve power?

So then we should be given control over that. The stock GSII had lots of control over the screen color, and power saving features.

Pink stripe down middle of screen

On my E4GT, when I turn the display brightness really low with my ScreenDim app, and then look at something (e.g., a PDF file) which fills the screen with a white background (and black text), while being in a dark room, I can see that the middle third of the screen is slightly pinkish, forming a pinkish vertical stripe, instead of white.
Does anyone else have the issue? If you want to try to see if yours has the issue, you can use ScreenFilter and turn the brightness really low, or you can use the free ScreenDim Trial and set to 25% or a bit lower (in Easy Mode). I'm wondering if I should return the phone to the store, or if they're all like this.

LOL, good for you for being persistent AR.
I tested this for you on mine and I'd say mine is a little over half on the left side as what you described.
Edit: Title is a little misleading but your initial comment about the whole left side of the screen seems to be correct.
Sounds like a symptom of the application. I have not seen a single et4g with a pink line/screen come through my service and repair centers.

This is something you wouldn't normally see in a stock scenario. The lighting app allows for drawing the screen down below 25% and the discoloration is very faint. I wouldn't probably have even noticed it unless I was asked specifically to look for it.
I don't think AR was pointing it out as a problem. He was probably just curious if anyone else could duplicate it using the same setup (well, and to make sure he wasn't really having an issue too I suppose ).

No, I don't think it's a software problem. The app lowers screen brightness to the lowest level allowed by the OS and then draws a light gray overlay over the screen. The device isn't rooted and the app uses standard documented apis. None of this should produce a nonuniform effect like this stripe. In theory, the same issue should come up if one turns the brightness to a minimum with the OS settings and them loads a light gray image. I'll see if I can produce it.
Also, you only see the effect well if you are in a quite dark room. But since I like to read in the dark, this matters to me. If all units have this, I'll live with it. But if it's only mine, I want it to be fixed.
This issue is one of the reasons I haven't rooted: I may need to return the unit.
You are right. I would want to know if it is my phone or not before I make a decision to have it replaced. What if the replacement phone not only has the same issue, but a couple of new ones as well?
Here's a test that doesn't require any special app.
Turn off automatic brightness and set brightness to minimum.
Then view this test image with the browser
http://pruss.mobi/test/A0.jpg
Zoom until it fills the screen. Go into a dark closet or other windowless room without lights. View the screen from different angles. To me, the discoloration is most visible if I view it in portrait mode, straight on. It disappears if I tilt the screen side-to-side a bit. Here is an attached copy:

The other issue my screen has is that if I view a 100% black image, and go into a very dark area (when I tested this most thoroughly, I was in a closed, windowless garage at night), and let my eyes get adjusted to the dark, eventually (after a bit of dark adaptation) I see an gray glow from the screen, with many irregular small patches that are completely black peeking out of the grayness. This is a very small aberration, but it is noticeable when outside at night running an astronomy app.
Interestingly, after a couple of months the problem seems to have decreased. Or my brain is screening it out.

How to make screen display black like screen is off?

As we know, SA screen is self lighting not like traditional LCD screen that needs background lighting , so it is possible to make display black as 100% pure black, in the dark doesn't even see the screen is on.... I have seen a picture comparable with IPS, SLCD... etc, which in the dark place you can't even know the screen is on when it displays black...
I just don't know what value set to make it happen, anyone has any idea?

What exactly are you trying to accomplish? Sure you can do it, but I can't imagine why on earth would you want to make the whole screen black. You can't use a black screen, may as well just turn the display off.

Still not sure why you want to do this, but you can get pretty close by viewing a all black pictures in photo gallery. I think there are also pixel tester apps in the market that can display a full screen of one color.

The reason most people are trying to figure this out is because it will save an abundant amount of battery life if less led's are being used when the screen is on.
I'm a little confused as to what you're trying to do, but some roms like AOKP you can turn off the nav bar. In which case, just find a totally black picture (or make one in paint) and view it in the gallery
Im using an app called no wallpaper from the play store. As far add I can tell it does just that, gives you a setting to have nothing as a wallpaper, pure black.
nope... i tried to view whole black picture , but still there is some background light like displaying grey when i place my phone in dark place , i can't set it 100% black like screen is off. can't figure out how is RGB and gamma setting
i know it is non-sense , but i am just curious about it...

I do not believe there's anything you can do about it. Even the amoled displays will have a very faint background lightning that can be seen when it gets dark. Amoled displays have very nice blacks but they are not 100% pure black.
I think that photo tricks you. As traditional LCD displays have much more background lightning going on. That photo is obviously exposed so that the little light that comes from the darker one has so little light coming from it so the sensor on the camera couldn't capture it with such a "quick" exposure that was needed to accurately display the background light from the LCD displays.

Very accurate post here. Here's a great video from XDA TV that talks about the differences:
http://www.xda-developers.com/xda-tv-2/truth-about-mobile-device-screens-xda-developer-tv/
There is a thread here about the GNex screen which, in a photo, shows that the leds dont turn off completely when it wants to show black. There still is some amount of light coming out.

Yep, just tested it with CNA. Turned off navbar, statbar, dock, used pure black wallpaper. Phone looks like it's turned off under normal lighting. But in a completely dark room there is a dim, gray, 1280x720 rectangle.

Notification LED

I cannot get the Notification LED to work. I mean isn't it supposed to blink when I get new emails? I tested it with the lightflow app and it works in that test, but other than that I don't know how to see it blinking? Could it be broken or I'm doing something wrong?

You may try to config the Email app or gmail app, if the led work with low battery ( blinking red) then it should not be hardware problem it just that mis config in some app s
I'm having the same issue.
I can confirm that the LED is functional, through third party apps that turn it on manually, but I have yet to receive a real notification flash. Fortunately, that looks to be more of a software issue which should be easily resolved.
Same issue on my end.

I finally managed to have it working! In Lightflow app, in notifications for example I chose gmail then for inbox under LIGHT tabI changed notification LED color to white and at the bottom of the same page, change the state of pm8xxx-led LED to: "Flash - Hardware controlled".
Now when I get new emails, the LED flashes! But its weird that by default this doesn't work.
Is it a single color or is it multi-colored? Only white is working for me.

I've never had any device with a notification LED before. Would it be possible, for example, to have the LED light up when charging is complete? That's about the only thing I'd want to use it for.

Yes, there are third party apps that let you customize this.
so selecting a differed led color with lightflow is pointless, huh.
So it's not an RGB led like the Galaxy Nexus, Nexus 4 and Nexus 10 ones?

No apps have been able to access other colors. This has led (hah) to speculation that it is not a RGB LED and only supports white. This is what my leds classes on my Nexus 4 (which has an RGB LED) look like:
And this is what the Nexus 7 looks like:
As you can see it's missing all three primary (for light) colors. Ignore the spotlight one, I believe that is the flash next to the camera. If we are to trust that the software is reporting accurate hardware then unfortunately it is only a white LED and will not be able to be adjusted.
EDIT: Looking at iFixIt's teardown pictures we can clearly see that it's a single color LED.

I'm having the same problem, assuming it will be fixed with a software update.
By making tweaks in Lightflow, I was able to get it to function when I receive emails.
However, it is very dim. Nothing like my SGS3, which is bright enough to be noticeable and actually alert me. I can barely tell that it's flashing on the N7, so I don't see much usefullness there. Not to mention a case will make it a completely moot point.
Is the LED supposed to light up while the tablet is turned off and charging?
How can I tweaks in lightflow to make it work

I was able to get the notification light to work for an email only when the screen is turned off. if I'm using the tablet & get a notification, it won't light up, but if the screen is off & I get one, it starts blinking.
my led light only flashes when the notification initially comes in, and doesn't flash at all afterwards, not sure whats up with it, would have assumed that it would blink again, but when I tested it earlier, it glowed once, then nothing for the next 2 minutes that I stared at it.
I thought my LED was 'busted'. Seems to work occasionally with gmail but not with other applications. It's also an extremely slow pulse. I miss it usually.

I've noticed a greenish hue on the bottom half of the screen. It's most visible at low brightness and greyish/darkmode backgrounds. Not visible on amoled-black backgrounds. Present both in 120hz and 60hz, and both vivid and natural screen mode. Intrusive enough that I notice it several times a day.
Anyone else have this problem? Is it software or hardware-related?

YES!!! I've had this problem since getting my S20 Regular on Saturday. I got this replaced from the store yesterday, and the new phone has similar issue, although it's not that apparent. What I also see is that in Light mode, the white is warmer at the top and cooler at the bottom. These hues are just inconsistent across the system, be it the Settings menu or different apps. Here's everything I've done to eliminate the issue but failed:
Cycle through all combinations of resolution+refresh rate
Switch between Natural and Vivid colour settings, including changing colour temperature
Turned off Adaptive colour filter from Dark mode settings
Disabled 'Use sRGB picture colour mode from Developer options
Force Dark mode from Developer options
Simulated Monochromacy
Performed Factory reset
Got the OS reinstalled at the Samsung service center
Apps in which I was able to see this issue in:
Most system apps like Settings, Messages, Dialer, etc.
Discord (especially in the channel menu)
Falcon Pro (Twitter app)
Gmail
WhatsApp
Telegram
Reddit sidebar
Gboard (dark themes with Key borders on)
Apps where this isn't an issue
Twitter
Discord (AMOLED mode. This doesn't change the side menu which is still grey)
I'm attaching pictures comparing my first S20 with an M30s that also has a sAMOLED screen. The green hue is visible in the dialer app in the first pic, and how this green hue distorts greys is visible in the 2nd pic in the hamburger menu. The S20 becomes lighter towards the bottom whereas the M30s remains consistent for the most part.
My current S20 doesn't show this behavior in the Dialer app (it mostly seems pitch black) but in the other apps, I can marginally make out inconsistency, and in this case it becomes lighter from the right of the screen to the left. Even in Gboard with a true dark theme, some of the keys appear lighter than others because of this.
I'm gonna try to get this replaced from the store tomorrow, but good to know that someone else is facing the same issue.
Had the same problem. It was really annoying. Every gray background had a strange green hue. You can also some a hue on other colors, but it’s not turning into green in all situations.
Yes, also on Ultras and plus. I returned the ultra because of it and got a plus. It is a lot more bearable but I have to confess that I ordered another Plus to see if it is better.

Did you get yours replaced?
I thought I could live with it but it is also getting extremely annoying on dark backgrounds that I had to turn off dark mode indefinitely. I think I'm gonna fight with Samsung to try to get a screen replacement at least (in a couple months when they get their shiet together) since it is not acceptable on a $1400 phone. I should have waited before selling my note 10+

Had my s20 about a week, tested my screen with At tu tu apk. OK.

No, I send it back to Samsung. Don't want to mess around with problems like this, when I spend that amount of money.

Having the same problem on the top half of the screen
Galaxy s20, exynos
So I just had a new software update (ATCH), and I'm happy to say this issue now seems much less pronounced! Still a slight discoloration under specific conditions, but definitely a significant reduction.
I can not confirm, that ATCH is making it any better on any of the devices I tried (Ultra, 2*plus). It made no difference at all, IMO.

Same here, no difference after the update. Clearly a hardware issue unfortunately, otherwise all phones would have the green tint in the same spot
I might a spoken too soon, as once I enable "blue light filter" the problem returns full strength. Though the update has made certain backgrounds true amoled black (such as in settings and dialer), which reduces the problem in these apps.
Yes, I haven't noticed any change with this update, which I installed 5 days ago.
Hello, Yes i noted it from first date. It was clearly visible in Phone, Messages, Notification centre and settings app and every Google app in dark mode. After last update it's OK, but for example Samsung Health or Feedly side menu it's horrible. Unfortunately Samsung store is closed because od quarantine.

It's apparently an issue with the devices manufactured on February-earlier. Most of the S20 devices made in March do not have the issue or have a less exacerbated green tint.
On number 5 I can say that it is finally bearable. It was manufactured on the second of march. I did not check with the rest. I only opened them, handled them delicately and checked them. All were terrible.
is this the problem with s20 exynos or s20 sd865?
Personally, I can only talk about Exynos. I would, however, suppose that it is through all kinds.
