In cm6 there is an option that allows you to change the rendering color that the LCD emits as a way to save battery. Does anyone know of an app that will allow you to accomplish this in any rom?
Changing the rendering color of the LCD on the EVO will not save battery life, because it's not an OLED display.
Thanks for the response. On to other ideas to save battery ...

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.
I'm thinking of getting the SGSIII now that it's out in black. I had the white version earlier in the year but returned it as I wanted to wait for black
I keep looking on the internet to see and find out if the latest version of Cyanogenmod includes settings to calibrate the screen but haven't really found any evidence to support or confirm this. I know there is sometimes confusion when using the word "calibration" when it comes to android, as users want to calibrate the accuracy of the touch sensors more so than the display.
In iOS, there's a fantastic tweak in Cydia called "Color Profiles" which allows the user to calibrate the colour of the display (system-wide, that includes gaming, video, apps etc). You get white balance, gamma, temperature and black level control
Is there any such option in Cyanogen mod; now or in the future? It would be great to have full access to RGB controls to calibrate an OLED screen
Switching to AOKP for a few days revealed that we can do much more with mDNIe beyond color saturation. the mDNIe settings in AOKP allows you to make the images (video, 2D UI and even 3D gaming) much much more sharper. I believe it used MSAA making the edges sharper and more pronounced. I liked it and saw that since MSAA is a natural ability of our screen, I was wondering where I could manipulate these settings in touchwiz. Touchwiz only gives you control to change color saturation but what about filtering? Is this KERNEL specific?
I've searched all morning for an app that would allow that but I wasn't able to fine one online or in the store so I was wondering if someone knew of one OR if anyone knew where the syntax was in which file, allowing you to manually change the settings.
Thanks
What's your lcd display?
1) dial *#*#64663#*#*
2) Version Information
3) Check under "TP:"
Mine is EBBG
Also, is there a way to adjust color temperature? I wish we had the color temperature settings for warm or cool displays
EBBG, too.
I like having on the night light mode all the time. I don't like the blue color all phones have.
Same here and I also think it's a little bit cold. But having night mode on all the time? Way too warm for me....
I had this also and my colors here is somehow slightly warm compared to my xperia z lcd

You can set the intensity. It's better for your eyes (or that's what they say). And you get used to it in a few hours But it's personal preference.

How to set intensity?
Just go to settings/display/night light. There is a slider there.
I also placed a shortcut in the quick tiles so I can turn it off if I want to and get to the slider.
If you get root and Kernel Adiutor, (maybe necessary to flash new kernel), you can set through kernel native RGB, saturation options, etc. It's called KCAL color calibration. There are posts at xda with even different profiles (think like 'how to turn lcd into amoled'). I don't have the A2, but since reviews complain about blue tint and lack of display calibration as in MIUI I thought this could be the solution for AO.
I also complain from this ****, I compred color temperature to my friend's phone (with miui)
And I found a huge difference in color temperature!!
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.
