Hello, is there any way to change the screen temperature of my device after rooting it? The blue filter of this tablet is very bad, as it does not change the relative values of the colors, but overlays a layer of color over the entire screen, thus spoiling the contrast and making the black colors horrible.
If you can provide any information about this, I would really appreciate it.

just picked up the tab about an hour ago, and just started playing with it... so far, so good
the one thing that stuck out at me so far is the color... it's at least 300-500K too warm, and waaaaaay to vibrant...
is there anyway to tone it down a bit ?
I couldn't find a way to adjust/calibrate the color on the device. I wanted my photos to look correct ... so I created an action in Adobe Photoshop that correctly adjusts the photos before I download them to the SGT 10.1.
Below is a copy of a post I made on the post processing forum on fredmiranda.com:
A little work allowed me to create a Photoshop action that will take images from my normal calibrated NEC 2690 work environment and apply a transform that preps them for use on the Galaxy Tab 10.1. In case anyone needs to get images looking good on a tablet, here is what worked for me.
In Photoshop, I created three adjustment layers.
1. Hue/Saturation - Reduced saturation (this was to overcome the highly saturated LCD on the Samsung).
2. Curves - I adjusted the individual RGB channels in the curves adjustment layer to get the right color balance on the tablet.
3. Exposure/Gamma - I reduced the exposure slightly and adjusted the gamma value to offset the gamma on the tablet.
Then resized the image for the small screen and applied appropriate sharpening.
I standardized on using sRGB for output. I left the original images intact ... this action can be used to create a a custom set of images for display on the tablet.
The good news ... I ended up with a beautiful tool for sharing images.

thanks
i guess that's the workaround...
not sure i like having to work around the color issue, but i guess it's better then sitting in front of a booker explaining why the model looks like she just took a bath in orange juice
I think turning off Auto adjust screen power in the screen settings helps the reds a little. There is also an app in the market that will let you adjust the RGB but for the life of me I can't remember what it is called. I uninstalled it because it made the launcher laggy but other than that it worked OK.
Found it: color filter service is the app. Its 99 cents.

will definitely try this app...
rgb controls would be ideal, and will allow me to use a colorimeter...
thanks
Does anyone know of a kernel that allows icc management of screen color?
Always loved this tab but the saturation sucks and the red it way down making things look purple instead of pink or red.
I remember this thread with the G3, http://forum.xda-developers.com/lg-g3/themes-apps/super-amoled-contrast-g3-display-t2817248, and noticed the setting exists for the G4 as well. It's under Accessibility > Vision > Screen Color Adjustment.
Has anyone played with it to improve color and contrast of the G4 screen?
I gave it more contrast by dragging the circle from the middle of the top down over the first blue candy. Tried to keep the same colors, but more contrasty. It's hard to adjust accurately.

As per the link above, already discussed.
Not worth it, ruins the display clarity and accuracy. it's not a true enhancement.
Hi! I have a 9506 variant, with a screen with slight color difference across the screen from top (cooler gray) to bottom (warmer gray).
I know, there are many such cases on samsung's amoled screens, and I also found that Cyanogen has a screen calibration, which can change the temperature for the whole screen. But is there a solution to fix not the whole screen, but partially, according to each screen's characteristics (user adjustable)?
You're probably looking for a screen filter app with adjustable overlay.
Though I don't think there are many apps with such a feature, as there aren't many requests for partial screen overlays.
Try CF.lumen. It was designed to adjust color temperature on the fly.
I have a custom image on my Always On Display screen but, despite being a simple black and white image, it is a lot dimmer than the rest of the items like the clock and notification icons. They seem a crisp white while the image is grey which loses some of the thinner lines in the picture.
Is there anyway to alter how it displays custom images?
To be clear, I'm not talking about overall brightness, I understand how that works with auto-dimming. I mean that the picture is greyed out and dim compared to the other, system, elements like time, date, etc.
Thanks
