Green tint

Do you have the problem that your screen has a slightly green tint?
It is possible to get rid of it by using apps like "filter your screen" (just add more red and even more blue). But there's no comparison to tools like voodoo color (v1 and gamma correction) on a galaxy nexus/s.
"Filter your screen" biggest problem is that it kills the good black level performance on an oled, contrast is lowered too much for my taste...
Do you guys know some better alternatives (even with enabled root or other hacks)?

It's a screen problem, not caused by the software. But it is possible to get rid of it porting a kernel module called "ColorControl" which was used in many Galaxy Nexus' custom kernels.

Yes during my Galaxy S days i used to have vodoo colour which used to make the screen look amazing, waiting for supercurio or anyother developer to port the option to galaxy note2

So you have the same problem?
As far as I know ColorControl is just a port of voodoo color from the Galaxy S1. So it should be possible to port it to the Galaxy Note 2 as well. Otherwise I'm going to return this nice device with that sh***y display. I will never buy a smartphone with an amoled display again!

Bad luck that you have got a faulty screen

Yesterday I went to a store here in Germany, and the Note 2 there had the same color cast.
I really like the Note 2 but I hate its display. This is embarrassing for Samsung!

Exchange your device.

Looks like this is screen problem, I have perfect white color. Try to test it from *#0*# menu (type this combination at phone app)

Got my replacement today: Gues what?! Exactly the same...
At least the build quality is much better.

I've noticed the same green tint that kind of goes away the brighter the phone gets. My eyes adjust after a few minutes though and I can't really see it. I would really like to get a colortemp/hue adjuster though.

Too bad you guys got faulty screens, as i have slight blue tint on my screen but i absolutely love this! I had One X 6 months and i would never want to change this display to that on One X, this is the best display i've ever seen. I guess it's just me then...

I always smile when I see you.
The phone is bad with out your touch

I think the color calibration is totally off on this phone. They chose to calibrate it this way, and it is out of my hands so it doesn't bother me because I love the device. Videos look great when I want to watch them.
Color is all relative because you cannot choose the color of the ambient light around you, so you are never seeing the pure color unless you are in a controlled environment. So why get hung up about how inaccurate the color looks on something in comparison to something else that's not bouncing the true color you're looking for?

Does the screen have a bluish tint in the whites similar to galaxy s3?

have they improved it? I can't find any close picture comparisons.. Thanks.

Looks better, but still there. I guess they're doing it to increase screen life or something, but absolutely hate that.
Once I installed Perseus on my Note II, I could hardly believe I'm looking at the same screen. Looks even better than iPhone 5 after calibration

yeah, but note 2 doesn't have pentile, doesn't it have a superior screen?

It does, yeah. But you can still see the bluish tint there. SIII/IV it's more greenish isn't it?
I have no idea why Samsung doesn't use RGB instead, is it because it isn't yet available for high PPI full HD screens?

I believe posters on here claimed cost reasons. too bad.. I prefer the overall design and build, screensize to handset ratio of the s4, but like the htc one screen..

That might not be apparent in normal vision though. S3 has noticeable graininess, but the pixel density on S4 should pretty much settle that IMO.
And I don't know if they took the screenshot with adobe RGB mode or saturated standard mode.
I love SAMOLED, but just wish if they could switch entirely to RGB. Wouldn't mind paying a few extra bucks either tbh if they implemented that on Note 3.

I don't think they can manufacture FHD 1080p yet. At least not in the amounts that the GS4 would demand at a reasonable price.

Yup, two issues: sharpness and color. It looks like the higher resolution overcame the less sharp drawback of pentile, but color tint looks is still there. need to verify what color mode the phone was in though.

welll, just got back from store. htc one's have multiple dipslay with different WB. but the s4 definitely had better WB in my eyes.

Why is this thread even open ? Amoleds will always have a bluish tint. LCDs always have better whites but suffer on black levels.

if you read my response, you'll see that the One has a more bluish tint than the S4.

Ink spots in S4 ?

A friend of mine used today a S4 and says it has some Ink spots.
Anyone else have Ink Spots?
.

You mean like these on the SGS3? I'd be surprised if the SGS4 didn't have them. The N2 did. My N2 may or may not have them because I've never looked at its display on a solid grey background with brightness turned down to zero in a dimly lit room as I don't typically use my phone on a solid grey background at zero brightness in a dimly lit room. There are always multi-page threads in every Galaxy with a SAMOLED display's forum talking about the "ink marks." Yet other then in the situation I described its never affected anyone in everyday use. People that this is going to freak out shouldn't buy a SAMOLED display.

What Barry said. Those blotches are pretty much standard. If you go "looking" for things, you could see backlight lines on perfectly white backgrounds on LCD too if you're REALLY looking for it. The thing is none of these are even nearly noticeable on daily usage. And neither do they interfere with your usage tbh.
That said, if you're buying the phone to view an entirely black image in a pitch dark room with low brightness, then avoid any AMOLED devices

GS4 has greatly reduced DC Bias. Much better contrast than the GS3 and Galaxy Nexus.

I remember having them on my old SGS3. Really annoyed me so I feel your pain.

It's called "mura" and is present on every Samsung device I have owned (GS2, Note, GS3, Note 2)

Yep, every single SAMOLED device, Samsung or not, has it AFAIK. Degrees might vary, but it's there.
http://forum.xda-developers.com/showthread.php?t=1365032
There are some members saying that apparently applying heat reduces the effect, not even gonna try it though. It is not that noticeable on my Note 2 even on low brightness/pitch black screen on pitch black room. S II users were the ones who had real torrid time with blotches.

Yeah, definitely don't try this. Can't remember where now but someone had this complaint about their Note II and went and used a heat gun on it. Suffice to say that "tiny annoyance" turned into a "I've got to call and get a replacement and this is going to be an awkward conversation". No idea if he got it replaced under warranty or not.

I didn't know.
Now i'm well informed, and will buy my S4 on May. :laugh:

I've had that on my SGS2, the screen was gorgeous so no worry.

I don't think even there are some black spots, anybody can recognize them
The black on S4 is tooooooooooooo black, much much much deeper black than Note 2
I can still see the luminance on Note 2 in dark room, not S4

Yellow tint issue on S4's screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?

Mine doesn't look like that, sorry. But I have lag. ):

Is it just in Chrome?
Try Chrome Settings ---> Developer Tools ---> Uncheck 'Enable Tilt Scrolling'

@raqball nope this is found everywhere, even instagram and facebook.

Ah, no clue then sorry..

@raqball can you do a quick check with yours, similar to the one I did and let me know what you get ?

Go to settings display screenmode and use something else other than adapt display. Im currently using dynamic and my tint is gone.
ATT S4 Rooted. Beastin.
4.2.2

I had it on standard all this time (including screenshot) .. Putting it on dynamic gives the same result :

Damn I was hoping it was that because it fixed it for me. Maybe a hardware issue?

@stevehkim I'm not sure tbh .. thanks for the suggestion though. It's quite annoying after I realised that it exists ... Didn't bother me before I noticed it :\

I found an app called Screen Adjuster but its not really efficient.

I had this with my S3 and got used to it. I was told in those forums that this is just how these AMOLED screens are made.

My display is perfectly white though... Side by side comparisons between the Note II, Microsoft Surface RT (perfect white display), and a Sony HDTV. My S4 beats or meets them all.

Can you post a picture comparing your screen to a laptop's screen ? I just want to see how different it looks. Also, do you suggest I return it to the store and get another one ?

I would return it rather than regretting it later. It defiantly doesn't look right.

Acer 24" LCD Monitor vs S4
I'll do one of my Surface or TV later.
I made a Pure White image to use for testing on the S4, use it instead of Chrome which uses a grey color in it's UI and for some reason the S4 screen brightness dims on Chrome automatically (and you can't change it). Download it if you want to do comparisons again.

welcome to xda? o3o
I get more red than green, but it is only when I tilt my phone at a certain angle towards a light source - one which wouldn't allow me to see my screen properly anyways. It doesn't bother me at all during normal use though d: Sorry I can't give you any helpful information haha

Thank you man.

What I saw on my and other notes is there is slightly blue or green shift when you look at angle. It doesn't bother me.. Not like flickering of brightness control....

Truth Behold, all AMOLED screens have a tint. Some will have pink tint, others will have a purple tint, some will have green tint, whereas others will have yellow tint. The tint should only be moderate, anything excessive is sure to be defective. These are inherit problems in AMOLED displays, some will not notice the tint as everyone's focal vision is different. Most unboxing videos from Day one will show the tint without the Reviewer's comments. The only reviewer that seems to comment on the hue is Erica Griffin. The newer AMOLED panels are still a lot better than the years before. Enjoy your Note 4.
Make sure your display is set to Adaptive Display for best results.

The custom kernel I'm using on my galaxy S4 has colour tuning built in. Are there not custom kernels for the note 4 that have this also?
Same with my old S1, and my old S2
Have a look through the custom kernel threads.

Are you suggesting its just how the screens are calibrated?

I don't know the cause of yours. The cause of mine is that the phone is a year old, and the blue pixels wear out faster than red and green, but tweaking the blue fixes it.
Just tweak the green down a bit on yours if you've got a kernel which can do it.
My screen looks horrible without tweaking the blue, and totally perfect with more blue added.
Edit: wait a second... It's perfect when looking at it straight on? Because that's normal if it changes a little when you turn the viewing angle. Only do calibration if it's got a tint when looking at it straight on.

Every Note 4 Owner has a tint somewhere on their display, whether its a pink tint, purple tint, blue tint, yellow tint, whatever the claim is; this is due to the fact of how these displays are calibrated. Viewing the screen from a particular angle usually corrects this, has nothing to do with the subpixel and life expectancy of certain colors on these latest AMOLED Panels. The Blues and Greens are now engineered to last long equally together in the current Note 4. The tint many are describing is to do with the gamma correction. Color accuracy is there, though based on the manufacturing dates the area of tint will vary. I was able to confirm this on '4' AT&T Note 4's all having the same pink tint in the same location. The AMOLED Panels in the Note 4's are far superior than its older gen panels.
It's good to know that there is a mod to adjust the amount of tint. Wish Samsung could have done this job on their end.
