Screen Calibration for Colors

Is it possible to change the screen color calibration other than just changing from Dynamic to movie / professional modes?
The biggest thing that bothers me about the Note 3 is that whites appear a cool blue, and not white especially on web pages and Facebook. Is this something that is possible to fix with a calibration or kernel or something?

There was a kernel for the galaxy s3, note 2 and s4 that had a very deep settings menu for color calibration (perseus kernel), but it only worked on exynos based devices, the dev said it was not possible for him to do the same thing on the ones with snapdragon because of a driver issue.. I will wait sit for this, at least you have a cool screen, mine is green and horrible. Let me suggest "filter my screen" on the play store , its just a filter, and it ruins pure blacks, but with it on the whites are decent now.

Thanks. Does anyone know anything else that may work?

Open the settings menu, tap the device tab and scroll down to accessibility. Turn on "color adjustment". Now you are suppose to tap the color box that closest represents the box shown. You can repeat this process over by pressing menu.

I there a way to enable ambient display like the note 4 ?

Is there a way to enable or port ambient display like the Note 4 ?

Issues i hav with my rog 2

its been 20 days i got the rog 2 and things i find annoying are
1. the whole screen flashes green when FPS is scanning my finger (MKBHD also discussed this in his review)
2. when you double click the power button a yellow border flashes around wallpaper on lock screen ( this only happens when you have two different wallpapers for lock screen and home screen )
3. when i open armory crate and exit, it automatically becomes default home app.
4. i disabled some google apps (chrome,duo,youtube,photos) but these apps are automatically enabled and updated every morning.
5. lastly RED TINT

i think u have played with some option from the developer mode go there and try to turn things off and see how that goes
if not then a factory reset could do something for u if its a developer option thing

Firstly what firmware version you on? Maybe more details would help
1. I don't get a screen full of green, but the screen is slightly brightened with a greenish brightness. I assume this is the issue. Most phones (inc Oneplus phones) with optic FPS do this as the bright green FPS light also partly turns on other oled pixels. Some other manufacturers lower the brightness of the finger print sensor light, which then has the effect of inaccurate print reads. I dunno, I like how fast the FPS unlocks the phone, its one of the quickest - if the slightly brightened screen is the sacrifice, I'm ok with that :good:
2. I can't replicate this
3. I can't replicate this
4. Why do you need to disable these core google apps?
5. Red tint is hardware - its been slightly improved with the latest WW-16.0631.1910.35 firmware, but this oled screen has a dominant red gamut - every oled screen has a dominant colour (either blue, red or green) so just have to deal with it. :good:

some users on reddit also reported that there home app is changing when they open and exit armory crate,
i use firefox and youtube vanced instead of chrome and youtube so i disabled them and i dont use duo or photos app either. i dont understand how these apps are getting enabled on their own and auto updating every morning? what kinda black magic is this?

Question Defekt screen?

So I bought my S21 Ultra last Friday. I lie with my mobile in bed late at night with brightness at its lowest with "dark mode". Notice that when I have dark gray backgrounds and open the keyboard, horizontal lines appear (thin light lines). They disappear as soon as I close the keyboard.
Someone who can test if you see the same thing?
So If I sent it back to samsung I can say that i have asked owners and they dont have that problem.
1 set brightness at minimum
2 darkmode on
3 120hz on
4 high contrast on keyboard
5 total black rooms
6 open play store and press search so keyboard appears
7 now I see thin lines (which disappears completely when I close the keyboard)
It looks like this

If it is application dependent (appears only when the keyboard is active), it might be a software alrifact.
Also, please bear in mind that OLED displays, when set to minimum brightness, might have a problem with displaying uniform colors. You might see clusters of tens of pixels that are just a tad bit brighter than the ones around. I've noticed this with every OLED display I have used in the last decade or so.

Ok thank you.
Yes it's only showing when i use the keyboard.
My old note 10 plus did not have this problem.

Different screen, different version of Android and Oneui, maybe even different keyboard, keyboard version or theme.

check app named Display Tester https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&hl=en

What model, carrier and software build do you have?
Software build: (settings > about phone > software information - last 4 digits of SW build number)
Is this happening in all the apps? or just the email as shown in the picture?
try it on safe mode and see if it still happens. maybe you are using a third party keyboard?

Display issue at 120hz and low brightness
My note 20 ultra has vague gray horizontal lines when displaying a gray background at the lowest brightness when running at 120Hz but it disappears at when the brightness increases or when switching to 60hz. Is this normal for AMOLED displays ?

Strange no one can test it so when i send it to samsung and maybe get a new phone and the same thing will show on that one to..

White balance settings S20 FE Exynos

Hello everyone,so yesterday i recieved my new S20FE from my service provider. At first glance it seems to be a decent device. Anyway,while setting up the phone,i found that the "white balance" controls under the display settings,dont appear to be changing any colour aspects of my screen at all. No matter how i adjust the Red,Green and Blue control sliders,the the screen remains exactly the same.
Am i doing something wrong,or have i missed something? When compared to my Sony Xperia XZ2 which also has white balance controls that actually work,i may add. The Samsungs screen appears very dull and the whites are more of a cream tone than actual white,which frustrates me. Has anyone else had issues with the colour adjustment on their S20FE and is there a way to get my whites from cream to actual white?
Any help or advice would be greatly appreciated.

@Trace.Oneil I have the 5G snapdragon version and tested Vivid screen mode today. it was so garish that had to try adjusting the RGB values underneath. that too made ZERO DIFFERENCE on my phone.
I quickly went back to natural.
PS, I can't remember much about it but I've heard there's a 3rd screen mode that's hidden and can be activated with ADB. maybe look that up.

Thanks,i actually found that online and gave it a try. Although there are some differences between the modes,the RGB sliders still dont work with any of them so you cant fine-tune your screen to your preferred colour settings which is a total waste. Why even include it in the software build if it does'nt work.

I was wondering if the other modes take too much power and that's why they were hidden.
maybe that could apply to the slider ?

I doubt it would be a power issue. The mode to me that is the most intense with colour,is Vivid and that is not hidden. I think Samsung forgot about the RGB settings to be honest,and that is probably why they dont work.
