Auto Color and Sharpness based on enrivonment luminosity - Xiaomi Mi 9 SE Questions & Answers

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.

[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.

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...

How to dim the GN screen even more?

I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?
Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.
Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.
CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.
i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.
Thanks for all the ideas. I went with the easiest one, Screen Filter.
AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.

[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?
h t t p://imageshack.us/f/202/20130221221021.png
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.

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!

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.

I totally agree that the default is over-saturated and the natural setting is washed out. You can use ADB to get hidden display modes, which may be more to your liking.

Interesting.
As I understand it the phone uses the correct ICC profile for what you're viewing.
The human eye is notoriously inaccurate when it comes to display calibration especially gamma correction.
I've tested cam to display throughput on the N10+, it's dead on. I run it in natural setting.
If I need more saturation I use some Provigil

As you infer, colour interpretation is very subjective.
So, to this end, using the ADB or other profiles is perfectly legitimate to tailor to an individual's needs. Irrespective of scientific measurements.

Actually what I'm saying is even the people who's color perception is in the top 10% can't dial in color correction by eye.
The other 90% don't have a chance.
If the device isn't factory calibrated correctly or if the display is defective these additional profiles aren't going to correct the issue.
It's nonetheless a cool hidden setting that may be useful. Unfortunately it's not easy accessible for shifting on the fly. Setting the display to anything other than natural will likely end up being an eye sore.
