I know where you're coming from. Just tried latest trinity today and whites had a purple tint. As annoying as it was i decided to stick with it a little bit and now i can honestly say i'm getting used to it and going back to other kernels with other colour settings is going to be really difficult. I can see it as a nice white now, where other whites seem yellow/brownish.

Different colored Gradients?

I've noticed my device has a different colored gradient than on most others I've seen on here.
For example:
In settings and after enabling hw acceleration in certain apps such as the xda app.You can see an obvious difference when compared to the settings menu on this video. http://www.youtube.com/watch?v=E2g_QhlvmaY&feature=youtube_gdata_player

Well apparently my screen looks like an LCD screen. None of the colors pop and the blues look grey. I've noticed the galaxy nexus phones that have the gorgeous display have the blue gradient and a darker non cyan blue for wifi and cell bars as well as the dialer. If your phone has the grey gradient and the wifi is cyan from stock. I suggest you take a closer look at your display.

I'm not really seeing the issue here. The gradient is supposed to be grey, not blue. The fact however is that the GN screen has problems with accurate color reproduction and the samples that you linked seem to have a lot of blue/purple color noise.

So what you're telling me is I'm one of the lucky few to get a good GN? Because before purchasing this phone I saw many video reviews for it and all of them had that blue gradient...not a gradient like the picture above you but still blue.

grainy screen.not a warrenty problem?

hi all xda members..as some of you might know that some galaxy nexus as purple tint and/or grainy screen.. well mine has a grainy screen at low brightness then at high brightness my screen looks like it gets burn in.. i sent it for repair and they said they cant see the fault or ''we could not replicate the fault mentioned''
are they stupid or??

From what I've gathered from reading around, this is the nature of our displays. However there are some mods out, that may help the grain and purple tint.
I think the thread was in general.

i seen it i think but nothing really about grany screens. its only noticable on white and grey backgrounds.its really annoying...

I think it is normal for pentile. But I can only notice it on lowest brightness and even then I must admit I kinda like it. Looks a bit like paper and the grain seems to be a common trend now (YouTube background for example)

Well, I've checked play store now and you are right - seems to be noticable on all brightness settings. Still though, it is normal for pentile.
But I think mine is really bad? Or am I just over reacting?

you can use the CM9 gamma values. I can tell you some good ones.
Tell me and I'll try some when my phones back please
Sent from my EPAD using xda premium
Maybe take some pictures of it when you have it so we can see how bad it is.
Gamma are
Color Multipliers
Red .66
Great .66
Blue .89
Color Gamma Tuning:
Red -10
Green -100
Blue -2
DSS gamma set :
Either 1.2 or 1.4
These bring out the colors way better. You will still get the grainy and purple at 0 brightness. But who looks at there phone at that.

Been using that for a while, while I was using ICS CM9 or AOKP. Now I am on Jelly Bean and I have been using Franco kernel. Screen still looking good.

Lit black screen

Hey guys, question. On a black scree , I noticed the screen is not pure black, it has some light. Only noticeable in dark rooms, even if the screen is on minimum brightness.

That's normal. The device is designed as such to reduce transition time

I'm guessing there's no way to make it completely black?
I used to have a SGS2 and I really liked the blacks, without that light (at least not as noticeable)
Is there any difference? Battery or something?
Anything????? I can't be the only one that wants this
Amoled already shows black as 'more black' than tft displays. Currently no tft/oled technique exists that will display black as actual black (like when the screen is off) afaik.
Having said that, I really like the black on my gnex. Dark enough for me.

White looks yellowish

Hey guys, I don't know if its me but my screen is weird. My whites are really off in that they look yellowish.
I'm trying to tinker around in color control on franko kernel updater with the blue, red, and green but it hasn't changed the whites. I having touched the gamma things though..
Anyone know how to solve this?

go into gamma and increase blue
You need to adjust the multipliers.
Flash the trinity kernel & admire its beauty.

Nope, the blue gamma doesn't change it. Everything except the whites became a bit more "white" but the white pixels are not as white as before.

+1 for Trinity
Colors look amazing. I was wary at first but from the first boot after flashing the kernel, I fell in love. For me, I have found a significant increase in battery life compared to the stock kernel as well.

Mbh had it, adjust multipliers.
If you remove red+green or increase blue it'll become more white.
Adjust gamma to remove tint in the shadows after that.

I'm tinkering in every what way possible. Now I'm thinking its hardware problem. But I'll keep trying.
BTW, I am running Franco 240 kernel. I was on trinity, and it was better, but Franco increases my performance and battery life significantly.

I have the same yellowish screen, flash Trinity like everyone said and boom, white is white.
I'm using the trinity kernel with the liquid smooth ROM and my screen looks just as good as my coworker's SIII does. It is truly amazing how much better it looks...
Anybody know what the color control setting difference is between the two kernels?

Should only be in the defaults, unless....
Check if Franco includes omap gamma (preset tables) over my Contrast.
No it does not good sir..

Yea they support both omap gamma as well as your contrast settings
I am running liquidsmooth beta1 with Franco 240, the smoothness and battery life is so much better and its not a feeling. I experienced both kernels long enough to know the difference.
So I just need to know how to fix this colour shenanigans. There is just too many possibilities with the options but I haven't stopped trying.

Franco and Trinity, in my experience, both have good color settings out of the box. Franco's colors look a bit more natural to me, as Trinity's are a little "blue" to my eyes. There are a few other threads with users suggesting various color settings. Get Franco (which you already have, aparently) or Trinity and try out some of the combinations suggested. Some are quite good.
Here's one thread on the subject: http://forum.xda-developers.com/showthread.php?t=1521195
Best of luck
Thanks buddy. I'll try this out and report back.

[Q] How to fix yellow tint ?

My Note II's screen has a yellow tint. Whites are not pure white, but kind of yellowish-orange. :crying:
The thing is though if I tilt my device either way, I can see pure white.
The screen colors are way better on my old Galaxy S2 w/ SAmoled+, and I can further tweak the colors by using a custom kernel with screen tuning support.
Is there anything similar for the Note II ?
Not yet, but you Could try "Filter your screen" App from play store.
Sent from my GT-N7100 using xda premium
Thanks, but none of these apps are good because they simply add a filter on top and also affect blacks.
Guess I'll just wait for custom kernel color tuning support

Is there still no kernel and/or app that can change color profile of the Note II?
The kernel from this thread can do it, here's a link to my post explaining how:
