yellowish tint?

Does anyone else have a yellowish tint on their sgsii? When I tilt the phone a little bit the display seems to be more white. Anyone experiencing this?

I have it too and have tried 3 different ones

I can see what you mean, didn't notice until you said something. It's very slight (at least for me). I don't know of any apps that can change the color output of the screen, but this is something I would think a root would allow us to change considering you can see a "whiter" color when you tilt the phone, we should be able to reproduce the color balance (I would think).

Okay, thanks for feedback I thought it was just my phone. Cause my friend has the epic 4g touch and he doesnt have this issue. Hopefully this will be "fixed" when we have root.

I hope so too but honestly I'd rather have this than too much "white" and end up with a blue-ish tint.

is it very noticeable?
or does it only seem like that from some angles?

It looks like its white-white and not blueish white when you angle it.

You can see the difference in colors and its from any angle

I have the yellow tint as well. Ironically it's only when looking straight on the screen. Tilt slightly to any other direction and whites look perfect. I recall the Nexus S I played with had some tint issues with white as well.

Mine has a yellowish blue-green tint that shifts when I move the phone. It bugged me at first but I barely notice it now.

Tbh, All SAMOLED screens have this effect at least my old captivate did.
Wait until supercurio messes with our phones He fixed that issue for me on the Captivate. I'm pretty sure he's going to able to work his magic on our phones as well.

Turn off autobrightness and set it to 40% and it should be less obvious.

yup it's a common side effect of all the SAMOLED displays
it's less obvious when you have the brightness at around 30%

the only phone that doesnt is the nexus s.. because google made the color a little yellowish in an update. Maybe its the rom, or maybe i dont notice it anymore, but beastmod v3.6 seems to have white whites

[Q] screen Issue(terrible blue tint)

When i tilt my Nexus ever so slighty any direction the entire screen turns blue. Is this an issue that can be fixed with a software update or just a bad screen. Thanks for your help in advance!

Sounds like a bad screen, haven't heard of anyone else having that problem, take it to a Verizon store and show them and they should give you another one.
sent from my new love, the sexy Nexy

I have a similar problem, except that the screen appears to me to have a yellow tint when looking at the screen from head on and only appears normal when I look at it from an angle. I would prefer mine to be like yours, as it sounds like the blue is brighter overall.
Are you using a custom kernel? A couple of them do have more blue than the stock ones.
The screens on these devices do seem to be be extremely variable. I am now on my third GN after having had my original handset replaced twice and each screen has had a different defect. None of them showed colours properly. I have checked with ones in my local store, and they do not seem to be affected, which makes me wonder if this has to do with certain batches. Sadly, my carrier will not allow me to exchange mine for one in the store because I bought it over the phone. I'm now going to try going through Samsung to see if they are able to exchange it for one from a different batch.
With my old Galaxy S, I used Voodoo Control to get the colours just right.
If a similar tool becomes available to calibrate the colour on this screen, I'd be more likely tolerate this problem.

I've got a slight blue tint when I tilt mine as well. Is this normal?

Sounds normal to me if it only shows up when you're tilting the phone and it doesn't stop you from clearly viewing what's on the screen

The blue tint is just what happens with this screen. All the units I have used(including my current one) only do a small section of the screen, not the entire screen. So, if it is going over the majority of the screen then it is a bad unit.

Note 2 screen defect on pure black screen in darkness

On my Galaxy Note 2, if I display a pure black screen in a completely dark room, I can see that first of all, the "black" is not really black, but somewhat pinkish. And second of all, there are "really black" dots and lines across what is supposed to be "pure black" but is somewhat pinkish (like i said). Also, this effect, of having a darker line, can also been seen with say, dark blue on screen in a completely dark room.
This effect is not noticeable when white or other colours are on screen. I'm really sorry but I can't show you a picture of this because obviously a screenshot captures the digital signal and not the physical output and I don't have a good enough camera to take pictures of what I'm saying in complete darkness.
Is this a defect or just an unavoidable "feature" of Samung AMOLED screens?

you did not use the search function: i personally wrote a huge amount of posts regarding this, also in the note1 section!
search for "black blotches" or take a look at my posts. really lots of them are about this!
in short:
its manufacturing dependant and its luck of the draw to get a "good" screen!
samsung lives with this as not many customers complain(ed) about it, as most of them do not even notice it!

Mine is pure back at full brightness when seen in a dark room (no pinkish hue or any line that you mention). And Note 2 screen doesn't even have the infamous black clipping/crushing issue like its predecessors! Blue colour also good, no issues for me.
No, it is definitely not an AMOLED feature or drawback (never seen it on any other AMOLEDs either)! Of all other aspects samsung SAMOLED screens are known to have the deepest blacks (with best contrast ratio). Sure, it sounds like you have a defective screen, and my suggestion would be to get it checked up at SC for replacement.

i also have a similar issue on my note 2. a black screen is not completely black, but a brownish black. And i can see 3 (or more) dots which are completely black.. i can see this only in a dark room, so normally this is not an issue. But when i read kindle in my bed with dark background, this really bothers me. initially i thought this was some smudge on the screen. im sad to hear that other people are also having this issue..

I had the black dots on my galaxy s2 ... but not my note ... The screen on my note has none of that sooooooo happy about that it really is just luck of the draw ....

Same issue here. But it does not bother me that much, and if I get it replaced, the next one might have worse issues.
Sent from my GT-N7100 using xda premium

im only worried if it will grow in time. like a dead pixel in an LCD screen, if this phenomenon spreads to the neighboring pixels over time, then its a very bad thing... otherwise, i am not bothered at all..

We need this thread each time there is a new phone which amoled screen? ..
The sgs2 has this as well as the sgs3 the note 1 etc.
it's not a defect, it's a limitation of amoled screen production.

Sorry, what you say here its not possible! EVERY amoled 'suffers' from this ('cause it CANNOT display 100% blacks, due to it's active matrix)! If you won't see it it's because of a wrong method or your eyes!

vertical lines. blobs..etc

am i the only one that is noticing this? while its not as apparent as it was on t989, this phone seems to have blobs, vertical lines and other screen defects
link to the issue thread for t989
http://forum.xda-developers.com/showthread.php?t=1300133
ive went through 2 phones(one had physical defect) and both had this issue, so im going to guess its probably pretty widespread.
anyone wanna check their phones for these as well?
since blobs, lines are not acceptable on a 600dollar phone like this
To find the blobs/lines, look at grey background at night with no other lightsource than the phone itself.

Mine has a small line but it's like dead in the middle of the screen.

mine too, only 3 small blobs, and a line
the thing with these screens is that the oleds are controlled by a voltage regulator, and when you turn the brightness down the voltage regulator can't neccearily provide enough voltage to the screen, which causes the issue we have
i was hoping samsung would have fixed this issue by now..its a surprise that they havnt

just to add
this is the kind of technology samsung needs;

No, this is not black crush, the blobs and vertical lines are something else.
blackcrush does exist for these phones, but mura and vertical lines exists as well.

i wish i could
having had an T989(tmo gs2)
initially the screen looks like what we have now
just look again in a year, the lines will become so apparent that youd want to smash your phone
in either case, it would bother a lot of people when they us their phone at night.
not to mention that this is a 600dollar device, it needs to be flawless!

nothing does indeed, which is why im glad my credit card gave me a 2 year warranty on this phone
in either case, ive posted this so people are aware that this issue exists, should they take action against samsung

The 1st unit I had were free of dark lines; but I am confident that it had the mura effect as well but was much harder to find since the dots were concentrated on the edges (near the bezel) of the display; if you look carefully at all the T-Mobile note 2's, they all have the AMOLED issue. I did notice on my first unit extremely faint stains throughout the display just like in the demo unit (in black background), but the lines were not there and hardly any dots. However, the whites on my 1st unit were somewhat dull, not as bright as the demo unit at the store, and had a yellow tint on the 2nd half of the display, and a light pinkish hue to some extent at the center of the display in a full white background, and also had faint horizontal lines (only when looked carefully) at lowest brightness in a white background (which became worse and more prominent over time).
My 2nd unit, though it does have a 1cm black line in the middle of the display, with 3 or 4 dots on the top and bottom left of the display, the whites are true whites, and the display is much brighter than the 1st unit I had. No yellow tint to be found, no pinkish hue, and no faint horizontal lines at low brightness and white background! Surprisingly, the color and brightness uniformity are flawless on my 2nd Note 2 (throughout the display, white is white, even brightness) , compared to the '3' Galaxy S2's, '1' Note 1, and 1st Note 2 I owned in the past. Best of all, the build quality on my 2nd unit is also better, no squeaking bezel or back cover, and hardly any blemishes on the bezel. The light which was leaking through the home button is almost gone after a couple of weeks of use.
So far, it seems like my 2nd Note 2 is a safe and clear winner; really hard to find a unitform AMOLED display these days and my 2nd Note 2 just so has one.
Why send something back as a result of finding the slightest chance of a mura effect when you might get something worse in return.
Like many say on the forum, "I guess you can't get it all."
