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

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

These colors gave me a headache... So Brilliant
I just tried the latest Samurai kernel with Voodoo Color and I am not a fan. I know a lot of people love it but personally I don't. At first boot your phone is dim. Then you have to download an app to set the colors. I tried several people's suggestions and didn't like any of them. So there is constant fiddling to get the colors the way I would like. Plus I had to turn my display up to about 35% when normally use about 15%. That has to eat up more battery, as well as constant adjusting. Then between the kernel and Voodoo app I am down 30 MB of RAM then what I normally have. I know for gaming it is probably the shizzle but for just a phone and browsing, not needed.
I flashed back to Samurai 2.08 and phone looks great still, lower screen brightness and actually is faster. Not sure if that is the kernel or lack of voodoo color.
Just had to get that out. I am sure this will open up a pros and cons discussion of voodoo color. I guess this would be a first edition of Kenny's Blog...LOL.

I dont really care much for it either. Whenever I start up a rom with a fresh voodoo kernel, the screen is piss yellow. I have tried a few different setting suggestions, but the screen is always way too blue. My friends drewl over this super AMOLED screen without doing anything to it.... i kind of agree with them.
Meh I tried it, thought itd be sweet, but not really lol. Using chainfire is better (Nightmode). Voodoo color is fun to mess with, for a few minutes XD

I agree. Didn't see significant benefit to having it either! (On the Epic) I think it can make a huge difference on other devices though, from images I've seen. Not to knock the Voodoo team as their work is awesome.
I AM a fan of CM7's RenderFX (and widgets) that can make the screen go all green or red or low cal night mode (and more) - each with a single toggle - is pretty damn sweet!
My feeling on this is if you need a program to custom tweak the nominal display colors as if its a high end digital cinema: maybe you got the wrong phone.

I like it, it makes my blacks blacker, and my whites whiter... as for the resources it takes, that I do agree with, not that it takes a lot, but 2.0.8 was a little quicker for me. I keep my phone at about 5 - 10 percent brightness all day. I think it looks nice though, personally I feel it is better then stock. And if you are getting the yellow stuff on boot, or on dim, probably have the wrong settings.

@kennyglass123
I've been tempted to post the same thing, but I assumed I must be doing something wrong because everyone else seems to love Voodoo Color. I tried every combination of settings that have been posted (including those above), and though they may add some punchiness, the colors always seem to be very unbalanced/inaccurate (either too blue, or too yellow, or too something else I can't put my finger on). I also tried dozens of my own combinations, just can't get it set to anything that doesn't end up bugging me after a while. Oh well, I'm going to follow your lead and flash back to 2.08 for a while and see if I miss Voodoo.
I like my phone really dark, and that might not be for everyone
Some of this may be due to inevitable inconsistencies in these screens of ours from their factory days. But I find VC to be preferable even at defaults. Colors seem much truer and the nasty bluish tint over much of the screen is lessened.
I love it. Not sure what it's doing for everyone else that doesn't seem to be causing a problem here.
Here are my settings, took me a bit to get my screen to where it looks best for me:

Wow.. are you reading my mind? I flashed it and ran for a few days. Even a very non-technical co-worker saw my phone and asked if my screen was going out since the colors looked weird. She always commented on how beautiful the screen looked.
Had to crank up my screen brightness turning off auto-brightness as well which is killing my battery.
Soo..what's a stable Samurai to go to? I'm not interested in voodoo, oc/vu, just plain ole I want my daily driver to work.
2.08 is the recommended stable replacement according to Earthbound.

I wouldn't call it a problem, just like I said, not a fan. I tried several suggested settings and no matter what on some screen something always seemed off. That and having to crank the display brightness up is just not for me. I am real happy with the beauty of the stock colors. I see the potential for the voodoo color but it would take too much work and adjusting until I would be happy with it.

Did you try the other color profile?
im running Marcus's rom, which comes with sam 2.06.
I tried flashing the new sammy colonel last night, and aside from the fact that the colors looked piss yellow, it was really laggy.. to the point were i reflashed the rom to get 2.06 back.. didnt really see that coming
Also, Im not really sure what everyones talking about with the "blueish" tint of the stock colors. I held my epic up to my GFs Moto Atrix, expecting to marvel at how much better my samsung screen looked, only to find that (even on the stock, non-VC colors) it looked piss yellow compared to her moto.
So, aside from not wanting to have to eff with the color settings, the main kernal right now that has it, apparently, hates my phone anyways

Ok , I have two epic s, one is refurbished so I'm sure it has some mileage on it.
side by side the differences are noticable. Exactly the same except voodoo has brighter, blue tinted whites... A little better darks. I will post pics today.
the voodoo epic does look pretty damn nice, but in the end, its all about personal preference.

Only on 1st boot and look. Then I saw everyone using the 2nd profile and tried all the settings I can find. There was always something off, one was too blue, one was too warm, one was too brown, and all were too dark requiring at least doubling my normal brightness setting which uses up more battery.
I would spend time tweaking my TV a little but don't want to keep doing it for the phone. It is awesome that it is better than sliced bread for a lot of users but just not for me.

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.

The purpose of this thread is so people who have the green screen can open and see how their laziness contributes to their problem.

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.

Calm down. I wonder, if voodoo color just doesn't work they way you want it to, after messing with the sliders and you still aren't satisfied.. wouldn't it be best just to leave it alone?

I have installed Paranoid Android on my Note and noticed that there is severe clipping in the CM9 UI elements. Even the default ICS wallpaper , the one with the"rainbow" coloing stripes show severe clipping on the lockscreen. It looks just plain ugly. And since most of the CM9 UI backgrounds are a shade of grey, there is severe clipping of these grey elements to a purplish pixellation and to black. You can notice this if you take the settings page in Paranoid android or any other CM9 based ROM (assuming most CM9 based ROMS have the same default theme) Look under the status bar where the grey background fades to black and you may notice severe pixellation like issues at that area. Now, go to advanced, screen settings and MDNIE mode, you will notice that the clipping keeps changing when changing modes but its still there in every screen mode.
How many of you are experiencing this? Assuming a majority of the people who run Custom ROMS run a CM9 based ROM, why isnt this issue reported anywhere? I'm asking because, the issue is plainly visible in these grey areas and UI elements making the visual experience really bad. And why is Gamma Control disabled in these CM9 kernels? I believe lowering the gamma would solve the problem.
I've noticed that CM9 kernels have the worst clipping whereas in other stock based kernels, the clipping is comparitively lower, closer to the stock kernels.
So once again users of CM9, please do report if you face this issue.
CM9 users please report back because I havent seen anybody talking about this issue in any of the CM9 related ROMS thread. People seem to ignore an issue which stares back right at the face even in ambient lighting. Why havent this been reported?
I dont have much idea about who develops CM9 kernels for the note. How can we contact the CM9 developers and let them know of this issue and request to enable Gamma Control within the kernel?
Somebody please help me out here. Because its been a month after I bought my note and I've been struggling and doing my best to find a solution to this horrible clipping. I had got in touch with GSMArena and got this issue published, yet Samsung never responded, I tried kernel after kernel and realised that the intensity of the issue varies from kernel to kernel. I've seen that whomever I ask about the clipping in this forum says they have it but then everyone seems to be happy running different ROMS and in these CM9 based ROMs which look as close to stock Google ICS UI have severe clipping all over the UI and yet people dont seem to bother.
So what can I conclude from this? Is this an isolated issue or are all of you Note users who have this issue just keeping silent and living with it?
I do not mean to spoil anybody's peace or anything. I clearly dont know how to get in touch with the CM9 devs for the Note, somebody help me if possible. And if you feel that this is an isolated issue, do let me know otherwise. Because, when the basic UI shows severe clipping, the whole user experience is spoiled and nobody wants to live in fear with bright UI elements and bright wallpapers dreading the clipping if anything at all has to be dark. We paid a premium for this device and even Samsung seems to ignore. I have the SGS3 and there is no clipping on it but just that everything seems darker on the GS3 when compared to the Note. This alone shows that Gamma is a culprit here and I could just sell away my Note and just live with the GS3. But that doesn't help anybody who is facing this issue and wants to see a solution. Even I personally like the note more than the GS3 and I want to keep it but for this issue. Not everybody has the money to jump to the next flagship every now and then and for the people who spent their money on the Note doesn't have to "live with it" just because they decided to buy it without knowing such an issue existed. Not every store lets you try and trial their devices before buying them.
Samsung has even seemed to ignore the EMMC issue even after claiming they are "working on it" I dont see anything productive from Samsung's side as even a device which was previously unaffected had the affected kernels pushed to it via an update. So basically if it was not for people like Entropy who works day and night for that issue, Samsung could keep replacing motherboards for every random wipe a user does. They basically want to sell the note until the Note 2 and then this wouldn't be their problem anymore. Problems like the emmc bug is a MISTAKE from Samsung's part and they should be ready to repair devices even beyond warranty as the user may have only done the most harmless thing, i.e to reset the device to factory settings.
So, coming back to topic, how do we get in touch with the CM9 devs and enable gamma control on these ROMs? Most ROMS have gamma control under MDNIE settings which is greyed out, most probably because the kernel doesnt support it. This is the best I can do for the people who are affected by the clipping issue as I'm not a developer. This issue isnt an isolated case in my opinion and affects every Note I've got a chance to see.
It might help if you actually posted requests in the cm9 discussion thread? #commonsense
Seriously after reading TS long posts still*cannot figure out his problem
please post shots to show your issues
I have been using CM9 roms since build 2 and do not seem to notice such issues or maybe i am blind ?

Yeah. OP is TL;DR complaining about some "severe" issue I've never seen and no one else has.
As to gamma control being disabled - I should remove that from the settings app, as that's something supported by the I9100/I777 display driver but not ours.

Oops..I'm sorry for the long post. Its basically about the severe "black clipping" which has been affecting the Note since release. This issue is best seen when displaying dark shadows in images and videos. There were many threads discussing this issue. And GSMArena had published this issue in their news after I mailed them about the same.
What I wanted to tell was, I feel this is caused by the Note's screen having the gamma cranked up quite high and I believe lowering the gamma would resolve this issue.
The default CM9 theme shows severe clipping in backgrounds and UI elements. All the grey backgrounds, (the default theme) clip to black just below the status bar.
Even all the videos which have dark shadows are totally blocky due to this and the clipping makes them literally unwatchable.
I had reported this issue to GSMArena
http://www.gsmarena.com/samsung_galaxy_note_plagued_by_display_issues-news-4513.php
I wanted the Gamma Control feature which is presently disabled to be enabled in the CM9 kernels so that we can tune down the Gamma to eliminate this clipping
The same issues existed on the GNexus and was fixed with the Lean Kernel which had Gamma Tuning.
So once again, in short, I'm talking about the "Black clipping\crush" on the Note when displaying darker shades of colours.
All the notes have this problem, and we need to access to gamma control but as supercurio said it won't solve all the problems of the black clipping and banding issues

Satishp, i know what are you talking about. Just take a picture of your note and post it here. Of course, you won't use a screenshot feature but a camera.
I sold my note bc of the black clipping issue, but now I cannot buy an s3 or HoX cause their screens are just to small, that is, narrow. Gonna buy Note again and hope some solution will come out. It is too bad to buy a phone for its screen and get a crappy quality. Issue on s3 is solved with lowered gamma. Comparing with the Note, s3 has much darker screen. Sometimes too much.

Huh?
Everytime I turn my screen on I smile at how awesome it is..Hell it seems even better now that I have been using cm10 but i think thats just because its brightness seems to be overall set higher.

All of the speculation and misinformation of this issue is really starting to get frustrating. First, the issue IS with the hardware. It may be possible to reduce it's impact using software but the fact remains this is a hardware issue. How do I know? I have replaced my Note's screen and the newer screen I have isn't as good as the old one.
The new one isn't awful, it simply isn't as good as the other.
2nd point - everyone will have this issue. It is simply an inherent problem with the screen hardware and it is completely implausible that there are 1 or 2 'perfect' screens out there. There will simply be variations. Some people WILL have better screens than others. For some people the issue may be completely unnoticeable and for others it will be glaringly obvious. Don't judge or hate on people because their screen is worse than yours and vice versa.
3rd the issue is MORE noticeable at lower brightness values than high brightness values. If you have your note on higher brightness values then you're unlikely to notice it. In my case, I can not see any clipping if I am in a lit room. The only time I can see it is when I'm sat in the dark with very low brightness. As I said above this will vary from person to person.
I have attached 2 photos below. One is a normal exposure where you can see the clipping is hard to see. Another is a long exposure which amplifies the issue more and makes it more noticeable (I used a longer exposure on my camera to show this). Fortunately it isn't so bad for me, but for some people my long exposure image is the reality unfortunately.
Standard: http://i48.tinypic.com/4uxnia.jpg
Long Exposure: http://i48.tinypic.com/5akew3.jpg
Why have we got a clipping problem and can software solve it? I believe it is highly unlikely that this issue can be solvable. I also think the issue stems from one simple shortcoming to the screen; the minimum brightness achievable per pixel. The problem is the jump from this minimum brightness to the 'off' (perfectly black) pixel is too great. There is no transition. Can gamma control solve this? I'm not convinced. I think the issue is more to do with what the lowest pixel brightness the screen is capable of. For the poorer people this minimum brightness will be quite bright. For others the minimum brightness will be lower.
If any devs know of a way of controlling pixel brightness on a level where it can be noticeably changed and if it is possible to reduce this minimum brightness then sure, it would certainly be a possibility. But I don't think this is possible.
Part of this might be a limitation of the HD Pentile AMOLED technology. But if you notice, both the Galaxy Nexus and the Galaxy S3 share the same technology. For people who argue that the S3 uses a different manufacturing procedure, Samsung has no where mentioned this and its just an assumption.
The GNexus had the same issue but was solved with the LEAN kernel which implemented a gamma control within the kernel. If you've seen the S3's screen ( I own an S3 too, So I've spent a good time comparing), you will notice that the S3's screen is visibly darker than the Note's screen. Images tend to look darker and this shows that the S3's screen has its gamma set to a lower value which eliminates the clipping.
More proof for you, lets take the gammatest image and view it on our PC. Most PCs use an LCD display and still you can see the greys gradually fading to black.
Now increase the gamma of your display from your display adapter's color settings and view the same image again. You will see that you can see all the way upto 1 and then black just like how the image is displayed by the note.
http://forum.xda-developers.com/showthread.php?t=1800117
Now view a 720p or 1080p clip on your PC with the gamma values still high, you will see the clipping in every dark scene. Try it yourself.
This shows that gamma calibration can correct the issue to atleast some extent.
Hmm. There appears to be truth in what you say. Unfortunately the Note is lacking somewhat in the developer department. And the few devs there are have other pressing issues to deal with so the question becomes who can implement gamma control on the Note?

Yup. Despite being pentile, compared to my I9100/I777 the screen is even more gorgeous.
I'm on minimum brightness nearly all the time. No clipping issues whatsoever.

Yup, and it's even better when you switch the screen mode to "Dynamic" (Advanced Settings).

I have the clipping regardless of which mode I put it in, apart from the clipping the screen is mint, which makes me even more pissed off when I watch a movie and a dark scene comes on, then the shade between black and grey turns into a lego block mess. I really cant beleive so many people are happy with it, half of u guys must be blind, I exchanged my Note twice, tested my cousins and my bosses Notes, all have the exact same problem. I even bluetoothed the gamma test image to a few in carphone warehouse , same with them, even the samsung rep I spoke to over the phone said the one they have in the office also has the issue. Total crap imo, Samsung total FAIL.

Please take a picture if your note displaying the gamma test image (blocks numbered 1 to 20) with stock gallery app in a dark room, screen mode dynamic, max brightnes with auto adjust switched off, I bet number 4 is light grey, then number 3 is black, if so your device has black clipping. There should be no abrupt drop from grey to black, it should be a gentle fade.
Thanks.
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.

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.

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!!!
