Color temp

Hey guys, does anyone know if there is an option to change the color temp of the screen? I remember hearing the sgs2 had a feature to change it built-in. The color temp is a little too warm in my opinion. It might be on purpose to conserve battery but I would prefer it to be cooler (the whites are too yellow).

On my SGS2 I had an app called Screen Adjuster. It would let you change RGB settings. That might help, if it works with ICS. Other than that I know some ROMs for the SGS2 had different screen "modes" like Dynamic, Movie, etc.

Did the app work well for you? I'll give it shot man, thx.

On the SGS2 it worked amazingly well. Made the colors less saturated and more realistic. Of course, that's with the SAMOLED+ screen I think. I'm not sure how it will work with the Nexus screen. Different technologies, right? If you search the SGS2 threads for "screen adjuster" you can see some people's recommended settings for the SGS2. Maybe you can use that as a starting point and work from there? Good luck.

Yea I'm not sure how it'll react since the nexus uses a pentile arrangement while the sgs2 uses rgb. I've actually gotten used to it and don't mind it at all now. Haha go figure right. I guess my eyes just needed to adjust from switching from my vibrant with voodoo color which looked noticeably cooler.

Sorry to resurrect a dead thread, but I thought it was worth nothing that I tried the Screen Adjuster app, and while it worked for adjusting the calibration/color temp of my screen, it seemed to make my phone VERY laggy. Does anyone know of another app that will do the same thing but apply the settings permanently in some way without having the run the app in the background? Maybe with root?

Is my screen dying?

Hi guys.
I am on francos kernel with aokp m4. I know a lot of new features include LCD density, gamma and colour tweaks. I never messed around with any of those, because first of all I don't even know what most of that stuff means, and second I don't know what the benefits/downsides are to making those changes. So I left it alone.
I downloaded francos kernel updater and afterwards noticed very slight changes in colour. Everything below the halfway point of the screen has a different hue to it. Like a lighter hue. Its so hard to explain but its there. I deleted the francos kernel updater and it went away.
During the day I don't notice any of it, at home however it seems like it comes back. I then looked at Rom control for Aokp m4 and made sure all those settings were at default. Even then I notice it.
Also, this is gonna be hard to explain as well. Imagine diving the screen into thirds (vertically). I can literally see a line 1/3 down from the top when the screen is off. Its not as scratch or anything but I can see like the pixels. I have to take a torch to it but it is clearly visible. What is it? and does anybody else have it?
Second, 3/3 down in the screen (when it is on) I can see a transparent line (not when the screen is off, only when on, so it is a software thing?) and everything BELOW that is of a different hue.
Funny thing is I never noticed this stuff before, and I've examined the phone closely before.
I would take pictures but they wouldn't help you guys are gonna have to use ur imagination on this one lol
Any ideas?

Ha i have that line as well! Top third of the screen, about 2 pixels wide and going horizontal across the screen. Can only see it when the display is off. Shows nothing when on. I dont have your other issues though.
Install dead pixel detect and check each color and see what you find.

The color change is a kernel tweak. Try to flash GLaDOS kernel and your problems should go away

You can edit the colour settings yourself on Franco kernel with his app.

Thats the thing I have edited them to default, I've even gotten rid of the app. It seems like it goes away but comes back :S
Which is why I half think I'm seeing things but I swear the colours look off. Does Aokp build 28 have any of colour changes built in? I know you can change them, but like I said mine are set on default. Does it have any automated changes?

Just edit the colours til you find something you like.
There is a thread somewhere with peoples colour settings in it.
Give it a go and se if you can sort out your problem.
Here is the link, only a few different ones but give em a go

[REQ] App to tweak Saturation in SGS2

Hello to all!!.. is possible to find an application to tweak the saturation of the SGS2 screen!!?... it has the worst color rendition I saw in a cellular screen, I work in photography I can not even show the pictures in my telephone!!... I like this phone but with the screen of the iphone, miles away better.
Best regards!

Thanks for your feedback, the only problem is the Saturation slider, it does not work on my SGS2 and that slider is the most important
Besides that, that application is not done in good way, the RGB sliders has to modify de levels of color not the levels of brightness as the application do.
Moving all the sliders to the left has to decrease saturation not brightness as it does in a wrong way.
Regards!

I`m disappointed too with the screen colours.If I take a picture of white walls it seems to have a white-green colour.In my old HTC HD2 with HyperDroid-CM7-2.3.7,the white was brilliant white.If I put the same picture that I taked with the HTC in my SGSII,the white looks a lot greener.Is there a fix for that problem?

The colors of SGS2 are pure crap, I dont understand why there are lot of people interested in develop a firmware but they forget this part that is really important, you pay lot of money for a phone that gives you crap colors, totally biased and has no possibility to calibrate them.

Totally agree...My old HD2 with 5MP camera takes a lot better photos than SGSII.The problem is RGB calibration of the screen,not the camera.

Yes, I refer to the color rendition of the screen.

+1 for this... couldn't find any screen tuner/gamma adjuster/saturation adjuster or whatsoever for i9100 that work in ICS...
And my screen is way too blueish... and color is washed....

The gamma should not be modified, if some app is modifying the gamma is doing the wrong thing, it should modify RGB values or saturation remaining the brightness constant.

Hmmm, i thought it was gamma thing also... since I hate the blueish tint... I prefer warmer color.... >,<

What you are looking for is the Kelvin temperature to change, changing the gamma curve will change the behavior of brightness and color and that is not the way.
The controls that should have the telephone are real RGB controls without modifying the brightness, Temperature and Saturation, even better Contrast (but it should not change the colors), with that controls you could calibrate the screen the way best fit to you.

Maybe that's the control that included in CM9...

Yellowish tint by default? anyway to fix the color?

This is apparently NOT a problem. However, I would like to have some color fix on this.
I don't know if anyone knows what I meant
The One X screen compares to S3 or any other phone side by side, the one x had a slight warmer color tone, in other words, it's kinda yellowish.
it's truely visible on white screen.
I find this very disturbing, is there a way to fix this? I prefer a more natural and realistic color tone.
If you're gonna recommend an color fix app, can you tell me the input for primary color values to correctly fix it? I'm too lazy to fix it little by little lol.

It is going to be a colour fix app, but everybody has their own settings my cooler temp colour may be to warm for you or to cold. So you have to fiddle with it ti find your own settings that you like.
Give this one a try and see how it works: My Settings are alpha set to 8 and blue set to around 80ish or so.

[Q] Note 2 screen problem?

I bought my phone from an online store in Romania on February 22.I have warranty and other things, it was brand new. I kept the screen on full brightness, and Dynamic color mode. That's how I like it. I was aware of burn in so I switched colors with a display tester every 3 days or so. Yesterday I noticed that the spot where status bar is used to be in portrait mode is brighter than the rest of the screen when displaying blue, white and grey colors. Brighter not Darker. I searched on Google images and that doesn't look like burn in. It wasn't here until yesterday when I spotted it. It's barely visible with display tester but in Games videos photos and multi colored things it can't be finded, You need to look with max attention. I used Nova launcher to hide the status bar. I also heard that there are 2 different things, image retention which is fixable and permanent burn in. I searched for something like this but I don't seemed to find something good. I don't know what it is,I never browsed the Web without changing the pixels where the status bar is for more than 20 minutes. I heard burn in occurs in extreme cases. I don't know how this happened so that's why I'm asking you guys. I don't know even what to do it bothers me only in display tester, but otherwise the screen is perfect. Please give me an advice because I don't want to have a faulty screen.. Can it even be repaired under warranty for that?

No one knows what's the problem?

Maybe you could post a photo ?

Look at the top of the screen...That's actually what I'm seeing when looking on a blue test background.This kind of discoloration/brightness where the notification bar usually is when in portrait mode.This is not a screenshot or photo ,it's just a blue image that i modified to show about i'm talking about.It also happens on grey and white and cyan .I couldn't take a photo because i have a crap 7 MP shooter ,and one crapper 2 MP shooter on my old Galaxy Y.I tried them both but noone of them can catch thatstrange discoloration/burn-in/brightness
Xda don't let me to post links..That's the link without the X'es so delete X from this link to go to the image hXttp://i4XX4.tinypic.coXXm/2w4g39j.jpgX
I really don't know what this can be.

I have the same problem! I noticed it a few weeks ago. The bar on top, when in full screen mode, is slightly brighter/lighter compared to the rest of the screen. I can see it the most when using the browser. The screen looks slightly more yellow compared to the grayer (or something like that) bar. Remember the bar is not actually there, just the discoloration in its place. I have no idea what is causing this and I'm hoping it's not hardware related.

It ain't hardware if it shows up in a screenshot. Looks like the exact dimensions of the status bar, almost as if it's compositing it or it's shadow placeholder where it expects it to be. Try a different ROM, or install the Simplistic Framework and try changing the status bar's colour and transparency setting, see if it makes any difference.

I wrote that.It doesn't show up in screenshots.I edited a blue picture to look exactly like my phone screen.The problem I think it's the screen itself.And the reason for why I edited a picture is that as I said my shooters can't spot it.Any ideas?Also I use the stock ROM ,un-rooted..Everything stock ,including the notification bar.I just have a custom launcher wallpaper and widgets...

It shows up when you turn the phone in landscape mode as well. It remains on the side as a vertical discoloration where the notification bar resides when in portrait mode. I'm not pleased to say the least.

Exactly what's happening to me.

Made in china phones r crap..made in korea by samsung is gud quality

If you have the warranty the warranty, why not use it? Since the problem is from the phone itself.

This is same like what happen to OG note..i thought sammy already solve the problem when they using RGB instead of pentile on our note 2.. this is not good...
I check mine, so far nothing yet. But i afraid now!!

I also thinked that it won't happen on Note 2 too ,but here it is.I'll go further and I'll send it in the service ,after my holiday ends.This thread is good to maintain active because it may help people that also came along this problem

I always set brignest to auto and screen movie mode. So maybe it did save mine from that problem

My phone was on Dynamic and Full Brightness all the time.I love oversaturated and bright screens.LOVE AMOLED <3

Well I found a solution to the problem. It takes time to pull off and is still a work in progress for me but it's working.
I created an image that matched the resolution of the phone screen. I then made a rectangle at the top of this image that presents the exact size of the status bar and colored it white. The rest of the image was colored black.
I installed an app that keeps the screen on without dimming when plugged into the charger. Overnight I display the image I created with the screen set to stay awake and don't dim at full brightness. So what you see is a black screen with a full brightness white strip where the status bar is supposed to be.
This process quickly "ages" the status bar area and it slowly starts to match the rest of the screen. I've been doing it for almost a week and the difference between the two sections of the screen is starting to diminish. I bet a couple more weeks of this and the difference between the two sections will be gone.

I got the problem as well. And I'm telling as many people as I can because I'm annoying like that. Seriously, I hate the fact that I spent such money on faulty phone...Samsung galaxy note 2. <blech>
Unfortunately, Camera has stopped.
