I just picked up a Galaxy Nexus from WIND Mobile.
I have to say, the one thing I dread the most about AMOLED is the black/bright contrast. My eyes are very sensitive, and whenever I see something bright against an intensely dark background I get halos and it's very difficult to focus. For this reason I prefer LCD screens where the blacks are slightly grey. Nonetheless I decided to make the leap to the GNex because I like a lot of other things about it.
Do you think there is any sort of hack that could make the AMOLED look a bit more like an LCD? I realize this would affect battery life but basically what I'd like is to hack the colour space so that black becomes maybe 1-5% grey. I remember on CM7 there were hacks that could apply filters to make white into a more salmon-pinkish hue, a warmer white, etc. What I'm looking for is the reverse - leave the white alone but make the blacks greyer.
Anyone think this might be possible?
I don't know a specific solution, but here are some options:
If you're rooted, francois kernel and app can adjust the Gama levels, affecting all colors, but may help.
App Log graph can adjust your auto brightness levels.
Yes I am rooted.
Does increasing the gamma change the black levels? If so that could help.

It seems to depend on the app. Some apps have a gentle dark grey gradient in the background. But the stock taskbar, even at full brightness, is just as black as the same part of the screen is when the screen is off.
Not trying to be a comedian here, but have you gotten your eyes checked lately?
Seeing halos is linked to several severe eyediseases or wearing wrong/none correction.
+1. Yup.

Fair enough. Optometrist says my eyes are healthy but I have large pupils that don't contract very efficiently. As a result I get halo effects at high contrast even when using proper vision correction. It's not something that poses a health threat otherwise. But he did advise me strongly against laser eye surgery as there would be a high risk of halos getting worse.
So that's me in a nutshell.

Super dim is a root app and it can lower the brightness below the normal values

I'm not looking to lower the brightness - I know how to do that already. I'm looking to decrease the contrast by making the black levels greyer.

Hey all!
I've noticed that when my screen is a bit dimmer and I'm viewing whites like on Facebook or even in the xda app the coloring seems "dirty" and it isn't a clear white. Does anyone else notice this too? Is this expected?
Sent from my Galaxy Nexus using XDA App
I have noticed this as well and keep my brightness manually at about 35% to prevent it. From what I understand it is normal for this screen technology to display whites like that when the screen brightness is low.

I would like to see what people are using/tweaking their color profiles to...right now I am at:
Red -10
Green 0
Blue -2
And I am pleased with the results
Feel free to chime in...who knows we may stumble onto a kickass combo (albeit each phone is'nt 100% identical)
-8 0 8, but kernel calibration dont calibrate white color... still very yellow tint.. very bad
I'm using the latest franco, but where can I find the color profiles setting?

Its In the app you buy from the market...just do a search for Franco...

I'm assuming that tint was there when you first bought the phone right? Which means I must really test the phones in the shop for this tint before I buy it.
I'm using 2 0 -5 as someone else posted when it was first released.

What do the number values correspond to? (i.e. gamma/tint/saturation, etc?)
I've been trying to get the app for a couple days now and it gives me an error everytime

If it was a unauthorized to sell error, try it now, Franco was getting authorized by google and they wouldn't let anyone buy the app while they were doing that.
@fronc - IIRC its gamma
Can you post before and after screen shots?
sure..give me a lil bit...what are you wanting to see a screenshot of?

Changes the color brightness.
I get this weird problem when setting green very low: when the screen dims, it goes very green...
Yeah, I'm still trying to figure out what exactly this does...or at least what the use cases are of modifying these values.
I bought Franco's app to support him and for hotplug.....but haven't had the courage or motivation to mess with the screen settings.
What's the benefit of messing with these values?

+1 if I even set it minus one it'll go green at the lowest brightness.

This is simple: this mod controls the RGB gamma values. If you give it R it will give some extra Red into the scree, G for green and B for blue. You can range between -255 and 255, and with experimentation there's the possibility to get the best color profile. It's as simple as this.
But it is not possible to change brighter tones and whites without completely screwing up dark and mid tones. This was possible with voodoo color
-10,2-2
That was just a random choice, but I plan on testing new things.

I am also experiencing a green tint when the screen dims (if I lower the green value) I hope this can be fixed because the gamma on my screen is way too high and lowering all the values makes it look much better!

Same issue. Any time I mess with color values the screen goes green on lowest light settings.
I'm not sure if this is just my phone or its like this on everyone else's phone.
The screen has a general yellow tint throughout the entire screen when viewed in portrait mode. This generally is ok with me if it's even throughout.. However when I turn the screen clockwise to the landscape mode, and there is a clear white band without any yellow tint approximately a quarter of an inch wide on the left side of the screen. If I reverse the orientation such that I turn the phone 180 degrees to the other landscape mode there is another white band but this time only an eighth of an inch or less.
You can test this out opening up the browser to Google since there is a lot of white in that Web page.
Please let me know if it's just my phone or an issue with the nexus in general. I've also tried different rooms and kernels without any differences.

It's defective. Some color misrepresentation is normal, but white bands are not.
Thanks for the reply, I'm not sure if it's a software issue as the band is not there in portrait mode, and only in landscape. And that also changes from landscape in one orientation as compared to 180 degrees in the other direction.

In my eyes yellow tint is what you want. Blue tint means the display is of poor quality,

Preference. Cooler displays and warmer displays. I prefer cooler.
Problem isn't cooler or warmer display. It the fact that when I turn the screen to landscape there is a section on the left that is pure white without the tint.. And it not there when it's turned back to portrait mode.

I see. Well it sure sounds messed up.
Understand it could be a software issue but any sort of banding can't be good might be better if you just sent it to the service centre

You can fix the yellow tint with franco's kernel.

I was also having this issue but after I flashed MiNCO ROM this issue disappeared.
I suggest you to try this ROM it comes with Franco kernel.

Has any of you tried this app yet? maybe its useful to get rid of the yellow tint of the nexus 4? It was made by Francisco Franco

Judging by the reviews it should work. I know im getting it once i receive my N4.
It does work. I just don't know what each setting combinations look the best.

I don't notice yellowing yet. Guess if it appears, I know how to fix it now. Since it looks like software, why isn't this fixed?
Can someone post their settings for this app. Black's are too light and colors not as vibrant as when using cm calibration settings on the previous nexus'

This is a different type of screen. Blacks will not be as deep nor colors will it be as saturated as super amoled. As far as settings I use 255 190 255.

I use Fauxclock. It's got CPU/GPU clock and voltage control, in addition to color (and gamma, when ROMs/kernels begin to support it). You can also select an IO scheduler.
Basically it does all the same stuff as Voltage Control, SetCPU, Incredicontrol, and N4 Display Control, but it's in one app so it's overall cheaper.
I went to a Best Buy today and compared my N4's screen directly to a Optimus G. I didn't actually think my screen looked yellow at all until I compared it to the Optimus G. My N4's screen looked terribly yellow, was less bright, and had worse viewing angles than both of the Optimus G's my local Best Buy had on display.
Based off the first post in this thread for the GNex, I set my Nexus 4 to settings of:
182
190
200
I haven't tinkered too much but this seems to make things a bit better.
Has anyone else experienced the screen turning very yellow, almost brown, when viewing from the corners of the device? I am pretty unhappy with the viewing angles on the phone, especially after comparing it to the Optimus G, which is supposed to have the same display.

Do you think there is a limit set on the brightness maybe a dev could unlock that limit to make the phone more brighter

This app puts an overlay on top of your screen, so it doesn't really "change" your display colors. Also: the overlay should disappear when you try to install an app because of the security issues with having one in place when trying to install an app. I believe Lux and other similar apps do this too.

The screen settings definitely do not change when you attempt to install a different app.
Why do you say this is just an overlay? It is baked into the kernel.

I've gotten accustomed to oled and prefer it even over higher end lcd panels. Especially on this GS4 as oled has really come a long way. I like using the "adapt display" as it gets super bright in outdoor sunlight, brighter than any other mode when on auto-brightness. The colors look good without too much over saturation
