Colors on Android 2.3.4

After updating to 2.3.4, I notice that (to my eyes anyway) the colors seem to have been adjusted again. As we all know, Google messed with the color temperature in 2.3.3 to the chagrin of many. Complaints of yellow screens abounded. Mine had a slightly yellow tint to it as well, however it seems gone with 2.3.4.
I have always felt the best, most accurate colors available on the Nexus S were achieved with Voodoo. It appears that 2.3.4 matches it.
Are my eyes deceiving me, or are the colors really better? Anyone agree?

removed i was wrong

Something definitely seems different. Maybe a little brighter.

removed i was wrong

i couldn't tell any difference from 2.3.3. they look more natural, perhaps with a very (and i do mean very) slight blue tint. the whites are in-your-face as before, but i found it really difficult to read the browser before, now, it's not so bad.

The colours have changed, are better and look more vibrant. I'm happy again.

I have 2.3.4 and my yellowish tint is still here. Not a major concern to me but just figured I would share.

Yellow tint is still there. No difference in colour temperature.

Colors did not change.
However, I think the colors on 2.3.3 were fantastic, so.... you might not value my opinion much anyway

Display issues still not solved
I wonder when they will fix this issue.
I want the yellow tint to be removed. From what I read voodoo kernel fixes the issue. So I have 3 questions. Can somebody answer them?
1. Is it possible to root without wiping data?
2. Can I flash voodoo kernel on 2.3.4?
3. To test voodoo kernel do I need to root the phone?

1. Yes

I agree with this too. They're more natural this way. Yea, even though they've lost their saturation, but that's the whole point.

Until someone shows me a side by side comparison I am standing by my statement "the screen colour definitely changed" other than that, I don't know because I cannot really tell that well, I cannot say for the better or for the worst, please does anyone have two Nexus S devices to compare?

It's not true. You do not need to compare devices side by side. You only need to look at the source code which DID change between 2.3.2 and 2.3.3 but DID NOT CHANGE between 2.3.3 and 2.3.4.

People the colors are the EXACT SAME from 2.3.3, I don't know what some of you guys have been smoking LOL

If you guys really want to see AMAZING colors then do the following.
Flash Netarchys kernel (made for 2.3.4):
http://dl.dropbox.com/u/20870695/Netarchy Nexus/netarchy-nexus-1.3.0.8a-cfs-2.3.4-signed.zip
Then download Voodoo Control from the Market.
In Voodoo Control enter these settings (taken from Voodoo Colors thread) and then restart your phone

red: -55
green: -55
blue: -49
RGB Multipliers
red: 2689467840
green: 2883763840

edit
i take it back they are the same...was hard to tell because i did a fresh install of 2.3.4
But just installed kang CM7 nighty 2.3.4 update over my configuration with custom launcher, icons..ect that i have beeen using for a while and its quit noticeable

[SETTINGS & QUESTION] CM Color tuning, post question and settings here

Ok, i started this thread to discuss about new CM9 feature: the color tuning
The feature, with build 14, has become mature and then here we can share our best settings
Remeber that screens aren't all the same so colors can varie from phone to phone, but generally there aren't much difference
Please use this thread only for CM color question
The general cm9 thread is here
All other question will be ignored
so far i'm using
Red 0.917
Green 1
Blue 0.944
red gamma 11
green gamma 12
blue gamma 11
Setting must be with this format
Red
Green
Blue
Red gamma
Green gamma
Blue gamma
but i'm not 100% satisfied, so i'm working to get better possible

hi there...before i start fiddling with it..can u help me understand what each slider do?
Also..right now the CM colors are perfect but there is a lot of noise in darker pictures how can i correct it without making the overall picture yellowish?
thanks!
currently using
.591
.591
.591

First slider's series concern rgb adjustement, the second change the gamma of each color
I'm trying to understand how it works properly
With these adjustment you can mix red,green and blu and try to have best looking possible color
If you set all color t same setting would be few useless, we must try differents level to have acceptable black and white, which are the extreme opposite colors
Maybe someone can help faster than me

As I wrote in the CM9 General thread, your settings look amazing erto90.
I tried messing around myself but I don't have the eye for this stuff.

Ok thanks, but i opened the thread to share our settings
I've reached my settings after 15m of trying but i think we can do better!
So, guys, share best settings you can!

So messing around again with this, I just put gamma to 20 on all colors, using the color settings in OP, and I am really liking it.
Edit:
Red gamma 11
Green gamma 15
Blue gamma 11
Looks good too.
All at 20 became a bit weird after using it for a while.

My settings with balanced white and black:
0.868
0.632
0.688
3
6
5
Not perfect but looks for me realy good.

This is my settings, were made by a photographer friend of mine...
0.5
0.438
0.581
-14
-10
-7

My settings for yellow tinted screens such as mine.
0.680
0.573
0.884
-16
-20
-17
That's made to avoid the green bug at minimum darkness and to try to keep acceptable dark greys.
Sure it's still quite saturated but anything with more gamma turn the grey too bright...
Though I have to say it's better than Voodoo hack, perhaps because the MDNIE are disabled (they lighten the greys and turn them red on Samsung roms).

It's a kind of filter that boosts particular colours, quite like digital vibrance on your PC video card.
I don't like this, it gives more banding and tint in the dark greys.

Green Screen Syndrome

Its just a **** load of hyperbole.
Go into Voodoo Sound and scroll down to "Voodoo Color" and adjust the sliders.
NO ONE has the same screen/eye combo so what looks smexy for the kernel dev might look like a drunk heffer to you.
Personally my phone doesn't experience the green screen because I sat there and adjusted each value till I got the color reproduction I wanted (it may not be "true white" but I like my vibrantness ) so people, get off your asses and make your phone YOUR PHONE by putting in what you feel is the most comfty for your eyes.
If that's too much for you and you'd rather wait for the kernel devs to **** up their colors on their screen so that your BASE colors may or may not be correct, then maybe you shouldn't be worried about color and just stick with stock dull values.

Lol really? All I see in every rom thread is "my screen is green I flashed this kernel cuz I want voodoo color but I can't be bothered to read through 50 pages to see the fix". And the replies are all "SEARCH!!1!11ONE!!"
The purpose of this thread is so people who have the green screen can open and see how their laziness contributes to their problem.
I am all in favor of turning this into a settings discussion but the main purpose has been stated
Also, my settings are very inaccurate, not true colors at all lol but just raise your gamma a tiny bit and everything will be good

I see your point but i guess were just trying to get them to be less lazy is all haha, and voodoo color will depend on each kernel like shadow vs samurai but there kind of identical so pretty much same settings should give same results.

If by green screen, you mean the flash of green everytime I unlock my phone, then its not "laziness" that contributes to the problem, its the ShadowKernel. I am not going to raise my gamma settings so that the screen is completely washed out just so the green flash doesn't happen when I unlock my phone. I have been using voodoo color for a LONG time spanning multiple versions of androids and at least a half a dozen different kernels, and this is a the ONLY one that has had this problem. I have always used the "punchy" setting, and this is the only time I have ever seen that green flash.

I had the same green screen problem then I turned off automatic brightness and it stopped.

Its definitely your laziness giving you the green screen.
People moaned and groaned to bbelos about how he should incorporate custom settings into shadow so that they can have nice ass colors out the box, and on bbelos phone it can handle low gamma obviously which is why the gamma is so low and he put his values in and everyone expected it to lookk the same on their phones and couldn't be bothered with no type of personalization on their part.
If you can't manage to slide your gamma bars a little to the right to correct this problem, then don't complain when the fix is posted. You've obviously never bothered to mess with the sliders because if you did, you would've seen how much raising the gamma 2 values "washes out the screen".
Don't try to throw your $.02 in if you can't even bother to try it, otherwise your opinion is one sided and void.

Remember, samurai was a (very stable) hackjob kernel, pulling bits and pieces from every other kernel he can find.
I don't **** with samurai, but I'm pretty sure he has custom values set too, which will affect more phones than benefitting them

You're a blithering idiot who didn't even read my post. Making my screen look like **** isn't a "fix". I have run the "punchy" gamma settings on multiple roms and multiple versions of Android, and NEVER had a green flash when waking the device . . . . . until CM9 and Voodoo Color.
I like how my phone looks with all of the gamma settings set to -45. Yet you are telling me the FIX is to set them to -43? Hint, it still happens when the gamma is set to -30 for all values, and the screen looks significantly ****tier.
I do love how you make assumptions though and freely insult others based solely on your own arrogance. Its very cute.

calibrate the XZ screen for vibrant color

We all know that some of the color looks washed when we watch in a diff angle , also the head on looks sometimes may not look great since BE2 is not applied all time .
not sure if this works as I dont have a rooted phone ( dont plan to root till 4.2 ) can anyone test this on their rooted phone and post results and reviews please?

If you just want to deal with the view angle problem, set the system brightness higher (80% or higher), and set the brightness of the screen adjuster to 50%~70%, nothing else. Then the view angle will be amazing, but you will also find very little blue tint when displaying white color

Gpad screen gamma is too low

Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.
https://imageshack.com/i/nf96iaj
On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.

That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

I hope @dalingrin can cook something up to address both. He said he was going to work on something.

Yes it would be great if he did , though he's done so much for us already.

I see someone had developed a nude kernel for our devices. I welder off they can add support for gamma adjustment

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Gald to have helped would you be willing to try the kernel for the stock LG ROM?

Please take a look at the images below and compare
The tablet on the right is running my kernel and the left stock
You can see the differences on the first image as the deepness of the blacks
and on the second the highlights on the white

I just about to get this tablet, then i so this problem... ?

Be happy to. Have to acquire the device first, which will be in a matter of a week or 2
