Color temperature calibration? - Samsung Epic 4G Touch

Does anyone know if there are any working ways to adjust color temperature? I think most methods require a modified surfaceflinger library. My screen is sickeningly bluish green.
Thanks.

Sounds like a bad screen. I'd take it back. Mine is very balanced. Super saturated but very balanced.

I agree, my first one had a bad screen and a dead pixel right in the center, the screen quality on my new one is better all around and I wasn't even expecting there to be an improvement

Thanks for the suggestions, but the other ones I've seen don't look any better in terms of their greenish-blue color cast. I've read it's typical of AMOLED displays. I just want a way to adjust white balance like CM has.

...and I've discovered the answer. Chainfire3D's Pro version has support for Custom color "nightvision mode". Basically, exactly what I wanted. It works perfectly! Do yourself a favor and get this and drop your green and blue levels down a tiny bit.

You just saved me a two hour drive to get a new phone. Great find.

Different display colors?

So, anybody else have a chance to hold two E4GT's side by side? My wife and I are both trialing units, and mine has a much more pronounced bluish tint. I remember reading something about variability with Super AMOLED Plus screens, but the significance of the difference surprised me.
It's not that either one is so much better or worse, but they sure are different...

Settings>Display>Screen Mode. One of you could have messed with that setting. There are three basic settings that change the picture settings on the phone. Dynamic, Standard, and Movie.
I remember reading from someone who calibrates screen colors who tested this phone.
When new, screen has green tint as it ages it gets blue tint , movie setting has the most neutral colors.
My screen has green tint you only notice it when comparing another phone LCD or with HDMI on your tv
Edit I forgot I noticed my pictures have a green tint but that problem bad white balance ,compare a picture or the same screen with another good phone et4g has green tint in pictures too

Actually yes. My buddy has one too. Our screen settings are the same. Set with the same settings, and same wallpaper, his blacks are deeper and more defined and colors much robust. Both screens set to standard under display type

Why do I like the screen color of my Evo 4g more than the Epic 4g Touch?

I dont understand why these newer screens just look worse in coloration to me. It seems like all these new phones have a blue or green tint to the screens. I went to look at a Epic 4g touch in the store today because I love the form factor but the screen doesnt look as good to me. Is this fixable with some sort of calibration? Or is the hue always there? I want a new phone but I dont know what to do! I like the screen of my old one more!
What say you XDA experts! Looking forward to your responses!
I think you're 100% right. I remember comparing my old G2x screen to the display unit at the sprint store and being quite turned off by it. It even took me a few weeks to get used to the "bluish" color of the Epic... however.. I do so love that deep black. Wow.
Aagghh! So there's just no way to fix it? Seems like the only neutral screen these days is the 4gs

Check out "Screen Adjuster" by Netman in the market. It let's you adjust the RGB values of the screen, as well as the contrast.
Watching videos on the GS2 is very hard on the eyes if there are a lot of dark scenes... Most of the detail gets lost because of the deep black, even with the brightness turned up to 100%. This app lets me crank up the contrast as well so I can actually see detail in dark scenes.
Essential free app, in my opinion. It can be set to autorun at system startup, or you can run it on demand (that's how I use it).
Any way someone could post comparison screen shots? Would be interested to see how neutral one can get it. Also does using that program cause more battery drain?

There's a setting to adjust the colors to make it less saturated. Lighter colors especially white will never be pure white, then again there is no true black on an LCD

So it wont ever look as white as my evo 4g? Agh. I think I'll just wait for a Tegra 3 phone.

Before I used the program, I could watch 2 full-length movies streaming 3G via Netflix and still be at 45-50% battery. After I started using the program, my battery usage didn't seem to change, at least not that I've noticed.

My screen has never looked this awesome...

So, the other day I purchased a Datacolor Spyder 4 Pro screen calibrator. Being a photographer I want all my (primary) displays to look as natural and true to what my eye sees as possible.
So I decided to try calibrating my Gnex screen. I don't know any good way of doing this so I had to improvise, what I did is I first took screenshots of the entire calibration process and came to the conclusion that it simply shows 5 images: one solid white, black, red, green and blue image and measures it to define the accuracy of the uncalibrated screen. Then having told the calibration software that the screen has built in RGB sliders (the gnex doesn't I know, but I ticked the option anyway, you'll understand soon why) it then gives me a screen where it measures from a solid white image how much bias there is in either of the channels (red, green and blue) and gives a clear diagram overview, the objective is to adjust the RGB sliders of the monitor to make the 3 bars align (thus having no bias/tint in either channel for a natural reproduction). What I did here is that I used the color control feature available in various custom kernels (I'm using franco) and adjusted the color multipliers until' I my calibrator reported it being even and natural. I also used the RGB Gamma for some minor fine tuning.
I returned to the home screen and WOW, it's looks better than ever, grays are perfectly natural with NO GREENISH, CYAN OR PURPLE TINTS anywhere! Whites aren't perfect, leaning more toward a bright light gray, but worth noting I'm having only 31% screen brightness and I'm not sure if AMOLED can achieve a pure bright white image without a ton of cyan bias.
---
Tl;dr
Long story short, I got an hardware screen calibrator and used it to assist me get the most natural values with the color control in franco's kernel and it just pure amazing with none of the tints that the gnex is known for having.
My final values:
NOTE: These values may or may not look good for you, every AMOLED screen is different and needs different settings, these are simply the settings that worked for me, what's best for your device might be completely different!
Multipliers: 233 175 210
RGB Gamma: 1 0 1
Trinity contrast: 0
OMAP gamma: 1.0/disabled
Are the multipliers in order as RGB? Because these settings just make my screen look orangey
First thing, thank you for post:good:, i had looked for somebody to do a true calibration ever since i bought my gnex, having been spoiled before by my nexus s slcd screen, which was an excellent batch, so moving to the SAMOLED HD, for me, wasn't as great as i had hoped.
Still even after trying all the presets and fine tuning it still is slightly off.. (annoying thing with these screens not being all the same and being so different on quality, so you can't simply just input the color values and get the same result).
Anyway i like your numbers, they look pretty god on my screen.
Off topic: I'm probably wrong, but i think read somewhere that going over 200 on the color multipliers was supposed to make the screen more susceptible to burn in?

Thanks for the reply. They should be in order indeed. Note that every display is different so it may not be what's best for your individual device. Additionally, AMOLED screens I believe is said to wear/fade quite quickly compared to LCD with use and also due to the way the actual panel works in our screens each color channel will fade with different pace, effectively leading to unbalanced colors based on what you view on it; For example if you view a lot of red colors, the reds will start fading and thus everything will look a tad cyan-tinted. Finally there may be a difference in the kernel you use and the version of that kernel.
Simply put, unfortunately it's not guaranteed that what looks best for everyone else as each screen is different.
Oh, another thing I noticed; Screen brightness actually affects the color balance pretty largely. Higher brightness means less greens and more reds/blues.

And thanks to you for your reply. I actually believe I've heard someone that had used hardware to measure up the best settings for a natural 6500K color balance, but as I replied above, each screen is different and thus they were slightly too much on the blue/cyan end for me. To be honest, most settings I've tried that others have claimed to look great have always been too much green or too much blue. I've tried to adjust after my own eyes and gotten pretty close to what I believe to be good colors but always there is some kind of flaw, so I'm quite surprised to be honest I was able to get such a good overall result.
As for the color multipliers, I've heard it too but I have never seen anyone confirm it, so I'd call it off as a rumor. The burn-ins I've seen using values around 150-200 previously only apply to bright contrast colors and fades away within 2-3 seconds at most and 31% screen brightness is rather low I'd say.
---
On another note.. I just want to add that this isn't necessarily a full calibration but just an attempt to reach the most balanced color values. When it comes to gamma and contrast however I'm not sure it's really possible to mimic that of an LCD screen due to the way AMOLED handles blacks and produces very vibrant colors.

Actually deterioration is a problem with normal AMOLED screens. Samsung uses PenTile configuration to mitigate that in the SAMOLED and SAMOLED Plus variants. More info in the following interview with a Samsung engineer:

I put in these values using the Trickster app and my screen looked absolutely rubbish. There is no option to enable/disable Omap gamma in trickster, could that be the reason for the bad colors?

He's right, smartass, the screen shot is just the source of color, no matter how you calibrate your screen, every screen shot looks the same on other devices. We can only notice with real eyes contact.

Every screen is different, what looks good for me might look rubbish for you unfortunately :/
Also because someone asked for a before/after...
Now this will be highly unscientific and hard to reproduce but here's a before/after example (clicky for larger image):
Also advised you look at it with a good desktop monitor, and bear in mind that cameras are not perfect in any way so even if the camera settings used were identical and white balance set to match as closely as possible, it may not look to you as significant in terms of differences than it is to my eye. Nonetheless I can certainly see a difference especially in the gray and white tones.
The before example is not the stock kernel but simply the reference settings of all multipliers set to 200 and RGB gamma all set to 0. I believe this should be fairly similar to what stock kernel shows.
Still looks orangeish to me so I lowered red down to 220. But thanks anyways. I always love testing these.
A screenshot won't show screen adjustments...

[Q] White balance tweak ?? (SM- T705)

Can you explain to me how i can do the adjustment?
Do i need to root the tablet or from the menu? (The only tweak i found from menu is the color profiles : amoled basic, amoled cinema, etc) I have a sony xperia phone and it has an option to adjust the white balance with a slider!
Thanks..

Today I got two 8.4 Tabs, both wifi only versions in my hands and I was impressed, that the white color was different. Sadly, the whites on mine were a little bit more yellowish, warmer, and a little bit dirtier. Is this normal for samoled?

my experiences tell not all screens produce the same color, some are yellowish, while others are slightly blue, which can make white color a bit grey, etc
once i wanted to buy a note2 but i found its so bluish and therefore no deal
so each time I buy a phone, esp amoled, I will check the screen (and other things of coz) before I pay
I currently have 2 Galaxy Tab has 10.5 inch at home and deciding which one to keep. The main difference between the two is that one has a newer build date and love one screen seems to be a little more orange brown tint to the white versus the other tablet seems to be a little more blue yellow intent. Other than that perform identically however I did notice that when I run the CPU temperature app that the one with the yellow blue tinted screen seems to run a few degrees cooler most of the time except when using Chrome when where the other tablet seems to run several degrees cooler but only when JavaScript is activated.
One little trick in addition to adjusting the temperature using the adaptive display were changing from AMOLED basic to Evelyn cinema to make it cooler, is to go into the accessibility settings and then go into divisions section and then go into the area where one can do a test of their color as if they needed adjustments because of their own visual impairment. If you run that test and intentionally miss order the color tiles, and then will activate the option to allow you to adjust a slider which can further give you A white screen that seems to be somewhere in between the really blue display and the really warm AMOLED basic

Old thread i know but i just wanted to thank you for that tip Canadoc. I've been struggling with the excessively warm image from my Tab S for a year now and while putting it into "Cinema" mode fixes the white balance it also destroys the contrast by making all subtle dark detail just disappear. This accessibility method has given me much nicer whites without affecting the contrast other than removing the orange haze. I assume the colours are going to be slightly different now but i can't say i've noticed anything there. I wish the Tab S had the same display options as the Galaxy S5 has where you can choose the cooler white level without hammering the contrast too. Maybe it's something Samsung do in order to protect the lifespan of the blue sub-pixel?
So thanks again
When the tab s 8.4 came out the screen quality was a bit variable, but it's been months since I have have read of anybody having a problem, see if you cab get a replacement.

Mine's the 10.5 and this is the second one i got which was exactly the same as the first one in screen tone.
I always wondered if third-world country`s got B-C grade stock, as the consumer protection can be poor or non-existent, maybe it`s cheaper for the re-seller to buy this lower grade stock with screen color problems ect, I dont know?

UK here and bought from John Lewis. I've heard plenty of issues with screen temp on these ones so it's fairly common. Just using it this morning and thinking it perhaps wasn't quite as white as i'd like it and checked the settings to see if it was still in the proper mode and it was, switched it back to the old one and don't know how i ever lived with that brown tone!
Under different light sources it can take a few minutes for your eyes to adapt to the screen, so white can look a little off while this is happening, as the human eye will normally auto white balance anything you look at.
Does you screen when browsing with a white background at night, but not totally dark still not look perfectly white after a few minutes of looking at the screen.
Everybody seems to see colors slightly differently, and some not so slight, did you see the white/gold blue/black dress debate.

No it never looks like clean white to me unless i tilted it slightly back or forward and then i could see the tone shift to a cooler temp. I do keep the brightness down to under 10% most of the time and that doesn't help the white level either.
I can't say i ever understood the dress image, you can factually measure and define the colour on that one so i don't know why people were confused.
Have you had anybody else check your screen, do they see the same problem, though at 10% brightness the screen is never going to look really white, I always keep mine on Auto -5 , I have the RGB sensor set on Auto i cannot even remember what it`s really called as i have never changed it, but in Auto it is supposed to keep the whites looking white, what is yours set too.

Warm colours
My tab s 8,4 screen has a brownish layer, which makes whites mor brown and the colours less sharp. But when I put pressure on my tab, the "layer" goes away.

Anyway, i haven't had anyone else look at mine but i don't need anyone to anyway, it's a very overly warm tone. I've never used the RGB adaptive sensor thingy as it only works in a few apps that i never use anyway.

Do you see a much whiter tone when you choose Cinema mode? If so and you like it then you really should try the method in this thread to keep it without also cranking up the contrast.

Screen Calibration

Can anyone share their screen calibration settings? I wanna get the best whites possible. On my N9 I used to decrease the reds all the way to zero and my greens about halfway but this is a new phone with a different display and those settings aren't doing the same thing. So I just wanted to know what everyone was doing. Thanks.
I think natural mode supposed to be pretty much calibrated already and if you still wanted to tweak it more there is cool/warm white balance slider and rgb sliders.
There is whole bunch of tests here http://www.displaymate.com/Galaxy_Note10_ShootOut_1G.htm.

Natural mode can't be further adjusted. You have to choose Vivid to adjust RGB and color temp.
As far as best settings, it's difficult to say what yours should be. If the Note 10 is anything like the Note 8 or Note 9, you can lay four of them down next to each other with stock settings and they will all be different.
My Note 10+ seemed to have too much green tint and maybe just slightly cool. I left temp alone and just knocked green down one notch. But honestly, these screens are so close to perfect you can just leave it stock. Just play around with it, adjust it back and forth until it looks good to YOU. You're the one staring at it.
I have compared four Note 10+'s side by side, and all had different white points. Also, Natural mode was significantly greenish (maybe slightly yellow too) on all four devices. Personally, I feel like my Note8 has a better panel.
According to article I linked above and here again http://www.displaymate.com/Galaxy_No...hootOut_1G.htm Natural mode supposed to be calibrated and automatically switch between sRGB and DCI-P3 depending on content. (I guess sRGB for pictures and web, DCI-P3 for 4k TV) and can't be easily adjusted. Then there is Vivid mode which uses full color gamut, display is capable of showing and you can adjust it with sliders to your liking or calibrate using instruments. I can't tell you if all phones are properly adjusted at factory (probably not), but according to article the one they had was right on the money and mine seems to be fine as well. BTW the eye can be easily fooled and calibrating instruments are the proper way to adjust it, if you need it. Yet, it is my phone, I don't use it for pro use, so I adjust it the way I like it and mine is set as vivid and gray seems to be neutral gray as far as I can tell without any tinkering. YDMW.

One of the failings on Android, no color calibration.
You simple can't do it by eye and get all the parameters right.
It's fine for viewing but not editing photos until a company like Spyder steps up to the plate with a 3rd party calibration apk and tool.
Mine seemed best in natural mode with a slight amount of red added with an overlay apk and night mode turned at about the 10 or 20% level.
Lol, enough.
