[REQ] App to tweak Saturation in SGS2

Hello to all!!.. is possible to find an application to tweak the saturation of the SGS2 screen!!?... it has the worst color rendition I saw in a cellular screen, I work in photography I can not even show the pictures in my telephone!!... I like this phone but with the screen of the iphone, miles away better.
Best regards!

Thanks for your feedback, the only problem is the Saturation slider, it does not work on my SGS2 and that slider is the most important
Besides that, that application is not done in good way, the RGB sliders has to modify de levels of color not the levels of brightness as the application do.
Moving all the sliders to the left has to decrease saturation not brightness as it does in a wrong way.
Regards!

I`m disappointed too with the screen colours.If I take a picture of white walls it seems to have a white-green colour.In my old HTC HD2 with HyperDroid-CM7-2.3.7,the white was brilliant white.If I put the same picture that I taked with the HTC in my SGSII,the white looks a lot greener.Is there a fix for that problem?

The colors of SGS2 are pure crap, I dont understand why there are lot of people interested in develop a firmware but they forget this part that is really important, you pay lot of money for a phone that gives you crap colors, totally biased and has no possibility to calibrate them.

Totally agree...My old HD2 with 5MP camera takes a lot better photos than SGSII.The problem is RGB calibration of the screen,not the camera.

Yes, I refer to the color rendition of the screen.

+1 for this... couldn't find any screen tuner/gamma adjuster/saturation adjuster or whatsoever for i9100 that work in ICS...
And my screen is way too blueish... and color is washed....

The gamma should not be modified, if some app is modifying the gamma is doing the wrong thing, it should modify RGB values or saturation remaining the brightness constant.

Hmmm, i thought it was gamma thing also... since I hate the blueish tint... I prefer warmer color.... >,<

What you are looking for is the Kelvin temperature to change, changing the gamma curve will change the behavior of brightness and color and that is not the way.
The controls that should have the telephone are real RGB controls without modifying the brightness, Temperature and Saturation, even better Contrast (but it should not change the colors), with that controls you could calibrate the screen the way best fit to you.

Maybe that's the control that included in CM9...

Over saturated

Is there any apps or anything that could help tweak the saturation? everything is ok in general use, but when viewing images they are way too saturated.
I've tried the screen mode. It's either too saturated or too dull. I need something in between.
Thanks

If you're rooted, have you tried STweaks? It offers some control over saturation. I'm using Samsung's Standard display mode with saturation at around -5 or -6. Most test photos match up pretty well with my color calibrated laptop display now.

[Q] Screen settings

Hi all. I've seen this feature in the first note and now I see it again.
Adjusting tone save the energy saver based on image analysis
Is this option really make a difference?

No 10 posts so sorry for link

I always have it set to off. I had it on but never noticed any difference. My guess is that if you are looking at a very colorful image, prolly the screen will lighten more up or over-saturate the colors to look nicer. Maybe even the brightness who knows.

According to a cnet article:
" There's another adjustment on the Note 2 to that significantly affects picture quality. Samsung applied the cryptic moniker "Auto adjust screen tone" (AAST) to a check box at the bottom of the Display menu. Uncheck it and the phone's full light output capabilities are unshackled, nearly doubling its contrast ratio and improving its ability to compete with ambient light. Turning off AAST also improves color accuracy slightly. "
Seems like changes the colour tone of brighter colours to reduce their brightness.
I keep it on since I like milder screens.
If you prefer low brightness and want to save power , keep it on.
If you find yourself using high brightness often, turn it off.

Thanks you for info.

Auto Color and Sharpness based on enrivonment luminosity

So, I noticed the screen changes its colors and text sharpness based on the environment clarity. Altough this seems a nice feature for using the phone on sunny days, the effect brings a strange oversharpened effect on the screen text. Not really a big deal, but I don't like it much.
Is there a way we can disable this feature? I've already tried going into "Settings > Display > Contrast & colors" and changing to "Standard", which should keep the contrast constant, but it seems the option isn't really working. I've restarted the phone and it keeps changing the colors and sharpness.
I made a video for you to understand what I'm talking about.

Thats samsung super amoled boosting brightness nits to increase readability,and its normal, it does happen in all super amoled screens including samsung note 8 and etc.
So it cannot be disabled as far as i know its in firmware of display.
But when you are in direct sunlight i think sharpness or color dissortion is not much of a sacrifice to increase readability.
Would it be better if you wouldnt be able to read whats on display ? dont think so.

For a second i thought my display was faulty but then realized its only for better readability. Not that I particularly like this but the sacrifice is worth it. For now haven't seen a toggle for it yet, but I hope xiaomi gives it in the next update.

Are you sure it is a feature of the display itself? Cause the brightness remain constant, what changes are the colors (contrast actually) and the sharpness...
And yea, like I said, it isn't a big of an issue, I just wanted to have control over it, but I can live with it haha.

I had this on my Galaxy S9+ and somewhat annoying under sunlight, though not as noticeable as on Mi 9 SE because of higher resolution and DPI. The only way to deal with it on my S9+ is turn off auto brightness and slide the brightness down to a manageable/readeable level.

Well my auto brightness on the mi 9 se is already turned off, and this keeps happening, so its actually unrelated to the brightness, more like a separate feature.

Have you tried disabling auto-contrast feature? It helped me.

How to turn off adaptive display? White balance and RGB settings not working?

Does anyone know how to turn off the s20's adaptive display feature? (I'm not asking about adaptive brightness.) I'm on a US snapdragon, unlocked, regular S20. Thanks!
I am referring to:
"Samsung's adaptive super AMOLED screen optimizes the color range, saturation, and sharpness of the picture depending on what you're watching or doing."
https://www.samsung.com/us/support/answer/ANS00063051/
The vivid/natural, white balance, and advanced RGB settings mentioned in that link do NOT seem to impact the adaptive display feature. (And in fact, white balance and RGB settings don't seem to do anything at all... If anyone has thoughts about why THAT is, or how to make them actually have an effect, I'm interested.)
I have tried turning off dark mode completely, turning off the video enhancer, and turning off the dark mode on wallpaper, but the problem persists and impacts things like apps and pages in Chrome - basically everything.
If I look at my task switcher, app screens will often look the way I want them to in the preview, but when I click on one, after about a second the display adjusts and changes the image to something brighter, whiter, and less what I want. This is true whether adaptive brightness is on OR off.
I'm trying to use a screen filter to manually set the screen to the settings I need, and it feels like the screen is fighting the filter and countering it, and I think this business with the adaptive display optimizing color and saturation could be the problem. Or if you have other ideas for the source of the problem, I want to hear them.
Any help is appreciated!

they removed the option to close adaptive display since Note 9 starting from s10 it is always on and can't be disabled

It was something like attached picture on Note 9

Ah hah! I think I figured out a solution to my problem (which was that the whites were too blue and bright and vivid as compared to everything else on the screen, no matter what settings I used on Twilight or another screen filtering app). For anyone who comes after me with a similar issue: the native blue light filter doesn't JUST turn on/off - it has an opacity setting which you can find and adjust by clicking on "blue light filter" in your display settings menu, to the left of the on/off toggle switch. Turning it all the way up (to the right) tones down the whites and blues without impacting the rest of the colors on the screen, which for me at least creates a much better color display ratio.
