[REQ]Tint of display?

Is it possible to change somehow the tint of luminescence display? Make it more warm or cold. Display in my SGS has a very cold shade, a lot of blue. I would like to add a little red to align white.

It's a characteristic of AMOLED screen. As you use it longer, the blue tint will start reducing.

Though that doesn't change the fact that the possibility to change or affect white point and/or gamma of the display would sometimes come quite handy. The color temperature of Galaxy's display is indeed quite high, yet it is so good picture-wise that this becomes an issue (ie. when viewing photos).

Just open any movie with the stock video player. Go to Settings and then Colour Tone. It will affect the whole system.you have 3 options warmer, normal and colder. Hope this will help

That's a great tip, thanks! Even though it's most likely just a bug
So you obviously can alter the display's color temperature system wide somehow. I wonder if this could be made into an app with customizable warmth settings... Too bad I'm not a programmer...

And speaking of the devil...

Menu - settings - 3º option
It appears blank on my phone, but leads you to temperature settings
The screen has a blue reflection when off. I also tested it playing the same video on the phone and on my laptop (300 nits LED screen) and the video on the phone was defintely more green-blue.
This is more noticeable on low brightness setting, try it on Kindle app, test settings, you have a slider for brightness. You'll see how low brightness leads to a blue-green tint, not neutral gray.

if some one could could develop an app for the sgs that does this i would pay.

settings menu is only available if you start the videoplayer app and select a video to play within.
if you start a video from the gallery, there is no option

Is the galaxy s i9000 different in this respect from the samsung vibrant. My vibrant does allow me to adjust color tone in the video player, but IT DOES NOT change the color tone of the WHOLE SYSTEM. Once I exit out of the player, everything is back to blue. Also the warm tone in the video player looks fake, just applies red on top of the blue, looks weird.

Decrease brightness

Especially at night the screen of the phone is to bright for my opinion.
Is there any app to decrease the brightness of the screen?

Screenfilter
On market + free = Awesome

What a brilliant little app. That is exactly what I've, been looking for...
Superb!
The only remaining thing I'd like would be a way to turn the screen negative too, so that I can flip bright white web pages to being black background instead. Happy to have the distorted photo colours this would induce.
Although thinking laterally, the better way to solve this in the browser itself might be with local css style sheet over-ride, (if it was possible?).
The negative screen mode would still be useful to flip other bright white apps though. Of course ideally, the screen would be negative inverted as well as having this screen filter available too, so that you could convert background to black and still also reduce brightness of text.
Anyone know if such a feature exists, or could be created easily?
Thanks
Mike

SIlly mistake

You don't need an app, just run your finger left/right on the notification bar to increase/decrease brightness.

the minimum brightnes is still too strong in dark, therefore is screenfilter needed

Lowest you can get from the notification bar is down to 8%.
With a few different brightness widgets you can get down to 0%, which is still blindingly bright and not much darker than 8% to be honest... especially at night in a dark room!
This "screen filter" software lets you make the screen much darker than 0% by adding a grey lens over the whole screen for when you want it darker. It works really well.

Wow i didn know screenfilter exist. *Rushing to check it out*. Finally no more blinding light when in my bedroom.

don't set it all the way down lol

[Screen Tune Settings] for Balanced Color and Saturation!

Possibly the largest complaint I have with the Galaxy S2 is the screen color balance.
Im guessing they did this for the wow pop factor that is so common when you're shopping for TVs. Yeah, looks cool when you first see it, but after a while, its bugs you. Well, it bugs me. The AMOLED screen has insane contrast ratio.
So after some mucking about, I got the color balance the best I could get on my phone while still keeping the contrast ratio the same. I avoided filter apps such as Screen Adjuster. Its not perfectly balanced, but Its Waaaay better from how it is stock. My settings may not work for you, but will give you a starting point to tune yourself.
------------------------------------------------------------
Requirements:
1. Touchwiz Rom or AOSP like CM10.1/CM10.2 (Pretty much any ROM will work I think. I did this on CM10.1)
2. Dorimanx Kernel (Important, will allow you to do some fine tuning) http://forum.xda-developers.com/showthread.php?t=1617219
3. STweaks. This is to access the kernel features. On the latest kernel 9.37, this app wasnt included in the kernel. You can find it in the play store here: https://play.google.com/store/apps/details?id=com.gokhanmoral.stweaks.app&hl=en
-----------------------------------------------------------
How to: CM10.1/ CM10.2 (AOSP)
1. Go to "Settings"
2. Click "Advanced"
3. Go to "Screen" tab
4. Click on 'Mode"
5. Set the mDNIe Mode to "Natural"
6. Now open the "STweaks" app
7. Go to "Screen" tab
8. Uncheck "LCD REDUCE POWER"
8. Set "Blue Color scale" to 132
9. Set "Red Color scale" to 132
10. Restart Phone
11. Profit?
---------------------------------------------------------------
How to: Touchwiz
1. Go to "Settings"
2. Go to "Display"
3. Change the mDNIe Mode to "Natural". I don't know exactly how to get there; I haven't used a touchwiz ROM for over a year... I forgot. But its under Display... somewhere lol (if anyone can tell me how to get there, ill update the post)
4. Now open the "STweaks" app
5. Go to "Screen" tab
6. Uncheck "LCD REDUCE POWER"
7. Set "Blue Color scale" to 132
8. Set "Red Color scale" to 132
9. Check "mDNIe Sharpness Tweaks"
10. Restart Phone
11. Done.
----------------------------------------------------------------------------------
Now the screen settings may not be perfect for everyone. But you can tune it using the color scale. The goal is to make the grays too look actually gray. Tune it so there is no shade of yellow, blue, green or red.
I tried to match the gray present in the Messaging app on CM10.1. Worked for me.
All credits go to the Devs who made this possible.

Will this work on Apollo Kernel 4.9? stweaks descriptions says it's for siyah kernel only? I'm running Neatrom lite.

EDIT:
Using the Screen Adjuster filter, install button on application installation panel doesn't work. Hence not recommended.

I use check. Lcd reduce, and set blue to 123 in stweaks.
Screen set to standard. Natural look awful

I havent tried that kernel. STweak works with any SII kernel that allows you to make some kernel tweaks. Its a frontend app.

For those not geeky, staying away from rooting may try an app on playstore SCREEN ADJUSTER apk. Worth trying though the adjustments required in my case were very minimal, increased marginally blue, red, reduce brightness a bit and lower contrast.

I mentioned screen adjuster in my OP. Although it allows you do tune color somewhat, the major downside is that it decreases contrast and lights up black pixels. this can decrease battery life. But I agree, If you are staying away from Kernels, than it works okay.

Nice. I Tuned the screen as close I can get to my Nexus 7 (2013). The i9100's screen is way supersaturated. But, I understand, to each their own

So, settings from first post is tuned to look like an nexus 7. Colors seems to pale forme then !!? I will try to set my s2 according to my Optimus g.

Good post, but one problem with this is that although it fixes the greyscale, the whites still look awful at anything other than full brightness perhaps. There is still way too much green, and I suspect Samsung made it that way due to OLED degradation issues with the S2 having a RGB pixel layout.I managed to fix the whites by modifying the excellent Galactic Night app made by arpruss, however I had some SOD issues that I suspected had to do with the app so I gave up on it.

If someone is interested I've developed an App called "ColorModeChanger" to change saturation and color mode of AMOLED screens. You can visit this XDA thread: http://forum.xda-developers.com/showthread.php?t=3154845

Here is my settings.. RR 5.5.2 rom. This setting is for cm12 based ROMs and looks great.

[Q] Screen Mode: Standard VS Professional Photo?

I've been trying out Professional Photo mode for awhile now but it just seems yellow-ish.
Standard seems to be okay.
Does anyone else have similar issues?
I was told that Professional Photo mode is more color-accurate

That mode has a larger colour space meant for certain professional photo apps. For movies, and everyday normal life use Movie mode. If you like exaggerated colours go for one of the other options.

Adapt Display Yes.
Auto-brightness No.
I use a Black Background on my Homescreen with White Text (DashClock) and it looks yellowish in either Pro Photo Mode or Movie Mode

I have tried professional photo as well, but somehow went back to standard mode. But for reading books, professional mode is nice as the screen looks warmer.

Weird, I use Ocean HD (beautiful live wallpaper) mostly since I got mine on a charger 90% of the time and discharge it fully every 2-4 weeks. Maybe I forgot to mention a setting or it is a defect of some kind (software or hardware).
Worst case you could reset your phone to default and immediately set it to Movie mode to see if your clean phone already has these problems. Hope you get this resolved soon, and by simple means.

maybe it is something wrong with my eyes. Standard is definitely more blue whereas Pro Photo and Movie are more warm in color.
there's a switch when I reboot my phone from Blue hue to warm.

Yes, after a reboot it starts at a default screen mode setting and after a couple of seconds it checks your settings and then changes it. I noticed this an hour or so ago on my Note 3.

The default is Adapt Display, which on your homescreen exaggerates colours, so my blue underwater Ocean HD screen looks even more blue. It switches to 'normal' blue.
I just checked some more settings, but are you by any chance using Power saving mode or any of those other fancy settings? Having owned 7 Samsung Galaxy devices by now I always immediately make a round through all settings and switch off everything that is useless (to me). I hate stuff like auto-brightness, which may be great in a car if you use the phone hands free.

hmm I use power savings mode but only Limit CPU and Disable Haptic Feedback. I unchecked Auto Adjust Screen Tone too (it supposedly saves power)
Do you use Lux to adjust brightness?
hmm. mine is a black background with just DashClock in White Text. it gets a little yellowish.
In Standard. it is like mint white.

I would disable Power savings etc. for now to see if it helps. I remember some option with "Lux" in it, but really I just disabled Auto-brightness and adjust the brightness level in the notification panel.

I gave it a try before but it still looks kinda warm/yellow. it is not like there is a yellow tint/screen but the screen just looks warmer.

I've actually never seen an Amoled with Perfect white color.. always a bit to the warm side..
I tried both Movie and professional mode, don't like them at all more yellowish/greenish on the white
especially when comparing it to an IPS LCD screen... then the NOTE 3 is very warm and a tiny bit greenish on white (standard mode) only really visible when side by side with example LG G2...
But then on the LG G2 skin tones looks a bit pale, and with to blueish/cold
so it comes down to what you prefer
I'm a bit torn between them... but when it comes down to choosing I think i prefer the Note 3 screen...
Remember NOTHING IS PERFECT

[Q] Issue - Yellowish color screen after flashing arymod 4.0 and Flex_Lollipop Rev2.1

Yellowish color screen after flashing arymod 4.0 or Flex_Lollipop Rev2.1, also tried 3 different kernels: LP_Xplorer_Rev1.7, darkqueen latest and perseo matergold. Still can´t get rid of this yellowish tint when the screen gets dimmer.

A photo would be good, I guess?
So you have only two options, either flash Stock ROM and have the display as it was, or you can use the app Screen Adjuster and turn up the Blue channel to neutralize the Yellowish effect. Remember, with that app you will just be masking the tint, not get rid of it, well not fundamentally.

Thanks for the help, I've also tried that app but the problem is if I neutralize at lower dim when brightness goes up the colors are messed up again. I´ll post screenshot.
I was going to post screenshot but it doesn´t show the problem and I don't have a secundary camera to take a photo.
xinfinityoO said to try and use synapse "Tip for the people with yellowish color hue
Go to synapse / screen and enable mdnie control , there you change the "Digital edge enhancement", try every sharpness value."
But color still messed up

Oh okay. Then you will have to ditch either the ROM or the kernel, I can't be sure which one is causing that (or maybe this is intentional), look for which one says stuffs about display tweaking, should be mentioned under the details of either the ROM or the kernel.
And screenshot won't capture that actually, a photo is needed, from a camera. Screenshots from all the Note 3 of the world will look all same.

I thought there was way to upload a synapse profile or something that could neutralize this. Everything works like a charm and at high brightness there is no yellowish issue only when it's dimmer.

Oh Synapse, no idea mate, have stopped using that buggy piece of software a long time ago (no offence).
