4.3 update bad color calibration and font atialising - Galaxy Note II Q&A, Help & Troubleshooting

I couldn't find people talking about this:
The update to Android 4.3 has changed the color calibration settings and they are wrong, even in Professional Photo.
I believe the calibration was the one intended for the new 1080p screens wich have other brigthness and different colors.
The result is that skin tones look awfuly orange in many pictures, and cyan and green are horribly oversaturated. Movie mode tones things down but looks totally dull.
Font antialiasing was changed too, probably for better results on the 1080p screens, but in the Note 2's 720p, all fonts now lost fine detail and look "bold" instead of "normal" typeface. That's not due to change in system fonts, it is system wide, web pages with custom fonts, applications etc.
It is a shame because performance wise, the new version seems quite snappy.
If someone knows a mod or something to get back the 4.2 color calibration and alter the antialising settings for fonts, please tell me :good:

Try devil's kernel with trickster mod or devils tools app. The kernel has colour calibration, I prefer devils tools but trickster has more colour calibration options

[KERNEL] [POLL] SpeedMod Color Tests

Hi guys,
In the next version of SpeedMod, I'll be making some changes to the color of the UI. In the JPX source code drivers, there are some new configuration settings which are interesting.
This kernel is based of K12F and should be stable. It is labelled K12G-TEST.
In this thread I will upload 3 different color settings:
Neutral
Warm (more yellow: use this if your screen is too blue)
Cold (more blue: use this if your screen is too yellow)
No color management
The purpose of this thread is to gather feedback from you about which color setting you prefer.
I realize that there are at least 2 types of screens with different colors - one which is more blue, one which is more yellow.
The file with "-warm" is the warm color version.
The file with "-cold" is the cold color version.
The file without "-warm" or "-cold" is the neutral color version.
The file without "-noc" is the version with no color management.
Reserved for future use.
On my friends SGS his whites are more like faint yellowish, on my phone its perfectly white.
So yeah there are panels that are probably poorly calibrated.
Thank you hardcore, i've never had problem with both version (normal and color) of any version of yours. So, normal is better i think
Have you thought about changing text color in CWM from green to blue or green like Amon-Ra recovery?

would be nice, let me explain:
purple: samsung (blue?)
green: zstupy
blue: hardcore (purple?)
red: supercurio
easy to distinguisch en you can tell by the collor what kernel you have

I'm perfectly fine with color versions developed so far...will I notice further improvements using neutral color version from this thread?

Haha... no I don't plan on changing it, and theoretically green is the best because Pentile-matrix AMOLED displays (like the one in the SGS) have the full resolution for green pixels, and less resolution for red and blue pixels.

Understood
Important is that it works always
I would try cold version, is it possible to have it at 256Hz?
Thank you hardcore
I also would be really appreciate if you could change the CWM color.
Maybe it`s not the best resolution on Pentile-Matrix-Displays but something special at all
I compared my SGS white level to my PC monitor (Eizo FlexScan S2431W), and I saw that it was a bit cold (blue).
Tried your warm version to correct it, but it seems too much for me.
To specify:
On low and medium screen brightness the screen is now too warm.
On full brightness, it seems OK.
Which makes me think that this matter is more complex than just adjusting one slider or setting or whatever, since the color temperature seems to change a lot with brightness.
On second thought I am not sure if my observations are 100% correct... maybe I'm just too used to a cold temperature...

Thanks for your feedback. So u find the warm too warm, versus your monitor.
Although it's a good basis for comparison, color balance is very tricky because it depends on the ambient light - if you are out in the sun, your display will seem more yellow (because sunlight is very blue). If you are indoors using warm lighting, your display will seem more blue.
The MDNIE software allows a certain level of control - at this point I can control the red/blue color balance which affects all brightness levels. This is similar to Samsung's own presets.
At this point I don't think I want to venture into trying to correct colors at different brightness levels - the source code also doesn't seem to offer that.
Mine is redish, installed your "blue" and it is just darker red...
Tonite I will install the new "no process" version, at least it uses less battery...
@hardcore,
Mention [POLL] on the Title.
Ooops, there is no Odin version this time...
Thank you for your good work!
However i prefer the noc kernel, colors are more natural, but it's my own point of view.
neutral here too
Please note that neutral and no color management versions are not the same.
Noc version has actually colder colors, from what I can see.

I voted for NOC, are you going to do an Odin version ?
Thanks,
The 'warm' version is PERFECT for my first generation UK i9000. Many thanks, been waiting on a colour fix for ages now!
Tony
For me the standard works best. The cool is too cold, and the warm makes the screen yellow. I find this strange because I was using the cool versions up until now. Is the color correction dial turned up a bit too much?

Edit the Registry here
I've actually tried this and there isn't a perfect way of accomplishing it. Changing the registry also changes other colors throughout the system and makes it strange looking. For example: the registry tweak in the thread the poster above me linked, has a tweak for the keyboard, but it is for the background color of the board. This color is also used for all the little sub menus (the things with the "..."). I changed mine to black because it does look better than the default grayish color (I tried changing it to white, but it just contrasts with way to many other things).

Colored darkness filters

I've been looking for apps that can apply filters to the color of what's being rendered on screen, I've found two apps so far. One is exclusive for samsung galaxy devices and the other is Chainfire 3D, which doesn't work on ICS. I was wondering if anyone knows of any apps or custom roms that can achieve this effect, basically make the screen even darker than usual by only displaying everything in one color. I know this is used for some OLED screens to save battery life, but it would be great for me in low light environments.
There's an app called Screen Filter but I'm not sure if you have the option to change the color.

[Q] Black Theme for Note 8.0

I see the note 8.0 has white background and black fonts on most menus, including music player and settings menu, how can i change it so it look inverted, i want black backgrounds and white fonts on all this screens like on S4.
Is there a mod? or a way to change it, i want it to save battery life.
Black only saves color on AMOLED screens since it turns off the unused pixels, that's not the case with LCD screens. So if you're hoping to save battery, sorry to burst your bubble.

like the other person said.. this is NOT a AMOLED screen, not going to save you any battery...
But if you do want to mod that stuff... you can root your device and get Xposed framework.. and there are bunch of Xposed mod you can do to customize your experience
Thanks, i didn't know that, in that case i rather have white menus, easier to read

Grayscale font antialiasing / reducing sharpness

I might be the only one (I didn't find similar complaints) but I don't like how S4 renders black text on white background. It's as if the "sharpness" setting was too high, plus I notice colorful artifacts coming from subpixel font antialiasing (for people not knowing what I'm talking about: forums.macrumors.com/attachments/screen-shot-2013-03-12-at-5-10-16-pm-png.402071/. In the past I didn't have problems with sub-pixel rendering, but the way S4 does it bothers me.
I tried changing screen modes and using custom fonts but nothing helps. After updating to Pie it's a little better but still not as nice as I get on my monitor or a phone.
So to sum up I would like to have two settings which I can't currently find anywhere:
- enabling grayscale font antialiasing
- reducing "sharpness"
The question is if the Modesty ROM or other roms have support for these settings, or they change the rendering engine?
