Green tint?

Just got my VZW galaxy nexus, and im loving it so far, but have noticed something odd: toward the top of the screen (about 1/4 of the way down from the top) there seems to be a very slight green tint, noticeable only when looking at a dark background (like the settings menu).
It's kind of hard to explain, does anyone else have something similar on their phones? Is this normal for amoled screens or should I ask for a replacement phone?

i believe it has to do with it being a pentile screen... well, 'HD' pentile, but still..
i'd say if you try an exchange, make sure you the test the other in store first.

can anyone with a galaxy nexus please post a photo of their phone on the settings menu? (scroll all the way down)

Pretty sure the setting menu is a background gradient with an intended color shift.
But yeah, mine has a blueish/greenish hue if I tilt the phone away or towards me in portrait mode. Straight-on, I don't notice anything.

yeah i am talking about viewing straight on

mine has this greenish tint slightly at the top right screen...
that settings menu then scroll all the way down is normal.. the color is not as dark as the top. I'm seeing greenish tint when on white background

I have a very light greenish tint on the right side of the phone on white backgrounds with text when at low/automatic brightness. The green goes away when I bump brightness to 40%+.
Did you try that?
Oddly, when I ran pixel checker, the pure white background has no green tint to it at all.

Yeah, at low brightness I see a tint/haze but at full brightness, everything looks beautiful.

Welcome to the world of pentile.

I see the same green tint on my screen. I thought it was normal, but I compared it to another unit today and saw that my display was both dimmer at the same brightness level and had a greenish cast and different color temperature than the unit I was comparing it to. I'm not sure if this is within the normal variance for these displays, but my phone certainly looks worse to me than the one I compared it to.
Both units also showed a green/blue tint when viewed off axis but with greater discoloration on mine. The second unit showed almost no discernible tint when viewing a white screen straight on unlike mine.

i have the same problem. Sometimes (usually after a power down and restart) my entire screen is very dark and has a, very obvious, green tint to it. I compared my phone to my girlfriends at the same display setting and the tint is very obvious (especially when i'm viewing menu, text messages, browser). When i adjust the brightness it seems to make it less obvious, but still there. However after certain power down and restart this "green tint" seems to 'go away' only to either gradually re-appear or just happen when my phone self adjusts to "automatic brightness" setting.
p.s. my phone also, had another minor issue of random re-start when listening to music (via google music) and adjusting the sound effects option. After that restart my phones display was significantly tinted and dark. Weird, Either way getting a replacement unit tomorrow.

Mine has a very slight green tint on the left hand side of the screen when at the lowest brightness and viewing a white background.
I normally have the brightness bumped up a bit, but it still bugs me when I have it low
EDIT: Checked pixel checker, has the green tint. I can definitely see it on the keyboard as I'm typing this though

I took my unit in to Verizon today for an exchange. New one doesn't have as significant of color shifting or banding issues.

yeah i got mine replaced the next day, all good now. No green tint, reduced banding, and much better viewing angles (the first one heavily tinted green or pink colors when viewing it from the right or left side, respectively)

Alright, got a replacement today.
No green tint that I can see, almost no banding and the colors don't change like, at all when I tilt the phone.
Now my nexus truly is perfect

Sorry, I find this very hard to believe. *ALL* pentile AMOLEDs change colours like crazy when you look at them at a sharp angle. It's a characteristic trait of this kind of display.
Pics from various angles or it didn't happen. ;-)

Tab S 8.4 Screen homogeneity issues

The reasons why I purchased a Tab S 8.4 were its awesome screen quality and high grade processor. For the later, the poor touchwiz optimization and the average gpu led to disappointing results. But well, the screen IS awesome !
Or is it ?
At first, I was truly impressed. But after some web browsing and reading e-books, something felt wrong with the colors homogeneity. On white backgrounds, the right part of the screen in portrait mode would tend towards a yellowish tone, while the left part would tend toward purple tones. Nothing obvious, but quite annoying when noticed.
After trying around with different backgrounds, it become more obvious with certain colors. The one used in settings background for example: The left side of the screen is deep blue, the right part is much lighter.. and greener.
Further investigating the issue, I figured it is most obvious when watched in the darkness and using dark colors: RBG such as R:0, G:10 , B: 20 or even R:20, G:10, B:0
Did anyone else notice similar issues ? Would you guys mind trying to create a R:0, G:10, B:20 (#000A14) background and check the result on your tab S in a low light environment ? On mine, it results in an obvious gradation from dark blue to green.

Attaching some pictures. The rendering is not the best especially in the darkness, but the issue remains clearly visible.

There is something very wrong with your screen. Return it.

I second that, that is not normal

I concur with the others, get it replaced.
AMOLED screens can fail for any number of reasons (pixel death is the main one) , if yours is showing problems get it replaced now rather than live with it and have a more serious problem later.

We've seen this yellow color issue reported by a few others. Looks like Samsung let a few diseased horses out of the barn. I concur with the others. Return it.

Thanks for your feedback, guys.
I'd like to highlight the fact this issue goes completely unnoticed in most scenarios. A friend I showed it on white background didn't notice it at all, in movies/games/pictures I don't see it at all. I only felt it while reading, and even then it was not obvious, just a persistant feeling that led me to further testing.
Only the extremely dark colors seem to be affected, and even then it's only noticeable in the darkness. I will go back to the store tomorow and exchange it for a new one, but I'm wondering if the issue isn't widespread and simply went under the radar as its effect is hardly noticeable in 99.9% of the situations.
Did anyone else check at an homogenous R:0, G:10, B:20 image in the darkness with their tab ?
I personnally used Moon+ Reader's background color settings for testing purpose, pretty easy to set up.

New Tab S, same issue
I changed my Tab S 8.4 today for a brand new one. Same test, same issue: the background is still not homogeneous. The issue is visible in the darkness on dark colors such as the one used for the settings menu, which seems naturally gradated from deep to lighter blue on my screen.
Could someone else test and reproduce the issue on their tab ?

I have tried to reproduce what you're seeing on my 10.5 and honestly I can't. I'm not going to say the white is always 100% pure white but it's close enough. At the same time I'm trying to avoid looking for something that's not there for my Tab.

Maybe you can go into Settings / Accessibility / Vision / Color Adjustments and see if your calibration is off. There is a test there where you arrange tiles by color gradation and it adjusts your screen. I am having none of the issues you mentioned, but my 10.5 Tab also passed that test with no color adjustments required. Give it a try.

Test completed successfully. The calibration is fine, and the issue is not noticeable during the test. The issue is actually not noticeable in most usages, I only see it on homogenous very dark color backgrounds (the 10% darkest colors), and while in a dark environment myself. In most common usages, the screen looks fantastic and flawless.
Unfortunately, I often use my toys in my bed in the darkness. AND I am concerned about a possible defect that would get worse over time.
That said, tests on similar colored backgrounds on other AMOLED screens (PS Vita, Galaxy SII) lead me to think this could be a global issue with AMOLED.

Lol, to those of us with a perverse sense of humor we would refer to that as a hanging curveball.
Whatever issues you are experiencing I would take that over LCD light bleed any day.

Dear Friend. Like you I am very sensible in that point. I have a lot behind me and I can tell you, that homogeneity is something we can not expect from all types of modern displays, except the pro ones with a special function that takes care about this issue. Any screen has such issues, the question is just what type of and the intensity differs. The lower the light in our environment the more sensible our eyes get. The longer we stare into the screen the better we see all color details. Worst case scenario is a totally darkened room. Your eyes won´t get more sensible than in such a situation. Especially AMOLED displays will show the strangest kind of irregularities you would never see normally. I remember the Tab 7.7 -- in a dark room the screen was over and over covered with black circles. Wow ! The Vita shows strange textures instead. It is horrible.
My advice to you would be to start trying to avoid using your tablet or any display in a dark room. Turn a light on, it will be nice for your brain and eyes and you will not see the described things. It´s just a matter of habit, nothing else. You will get used to it and probably feel very well with it. Anyway there will still be the green haze.... Not to talk about the yellowish etc. stuff.
I returned the Tab S for a MiPad and it´s much better, really nice homogeneity (compared to other actual devices).
I had 4-5 iPad Mini Retina and all of them have horrible yellowish/blueish tint.
I had 4 iPad Airs, 3 were horrible in a similar way, now the 4th one is okay, I finally had luck.
I had 2 Galaxy 12.2 - the first one yellowish in a quarter, the second has just a slight, short yellow stripe on the bottom border.
I had a Kindle Fire HD + HDX - both with bad, ugly green spots at borders and corners. Also partially yellowish.
Once I held a Galaxy Tab 3 in my hands that was actually flawless. I was shocked. It never happened again. Was from a classmate.
Today I guess it was a mistake since I could not test in in a home-at-night-environment.
I checked dozens of Tablets in big stores here - guess what I found ???
Look at the iMacs .... Horrible yellowish tint. Horrible. It´s a shame.

I use my Tab S 10.5 in a dark room with some regularity. I've never experienced any of these odd artifacts you guys are discussing. My black screen is just black. Colors look right. White is white. I think its a fallacy to claim that all amoled screens face these issues. The amoled screen on the Tab S is the best most advanced amoled screen ever created. Problems from older devices shouldn't apply here.
Please remember based upon other user input, Samsung did seem to have a run of defective screens on these tabs they put out.
Here's a quick video test taken in a pretty dark room (it's daytime here). As you can see the screen is just black. There is absolutely no reason to avoid viewing your Tab S in a dark room. If you are not seeing the solid black I have demonstrated in this video I suggest exchanging your possibly defective unit.

In my experience 100% of AMOLED displays exhibit this behaviour, i.e. both Tab S 8.4 I've had! The first one (exchanged because of unhappy whites) had it so obviously that it looked like a diagonal gradient fade to one corner. The second tablet shows it as a slightly patchy screen, see attached photo which looks worse than the reality.
This is only visible in a completely dark room with the display set to its darkest (or close to), displaying a very dark image (my photo is of the spec. you mentioned - hence blue/green colour). To show this I needed to use an exposure of about 1 second, if you use less the image will appear black, likewise (probably) if you try to capture it as a video using normal ISO values in camera, the camera won't pick up the background.

All I can say is that is seriously messed up. My screen looks nothing like that and just as pitch black as in my video. Considering black pixels in amoled screens are basically turned off, they should be utterly and completely black and devoid of light. Am I misunderstanding and your picture is of a blue background?
All other dark colors should be solid without strange light effects as well.

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).
Obviously under these circumstances an LCD would appear as a (relatively) bright grey !

[Q] Question about ambient screen

Hi, i was thinking of buying either a sony smartwatch 3 or a moto 360. Do all of you guys prefer the 3? Tge thing that has stopped me from buying the watch is the ambient screen. Based on your peraonal usage did you find the yellow tinge that noticeable? Do you have any pictures that you can show me just so I know its not going to be an issue for me. Also ive heard that the smartwatch is good for running? Is this true because thats what im looking for. Withthe ambient screen is there anyway to change the diaplay conditions so that that it is less yellow if I root rhe watch? Thanks for the help

yellow screen?

yes, you really should buy the SW3. I did it, and a friend bough the moto360, and he told me that he had a serious lack of battery, slow watch and so on. The SW3 works perfectly, has a great battery and the ambient mode is really good. On my side, i didn't notice any "Yellow-ish white". Definitely the best watch out there.

See attached picture....I like the ambient best on the Sony SW3 with a white background and black letters/time/text.
The background in ambient looks like one of those old LCDs and is very easy to read from all angles even in an office with less than perfect light conditions.
When you have a black background with white text it does look slightly yellowish, not bad in my opinion.

How did you flip the ambient mode? Typically it's white on black and yours is showing a black on white. Thanks

I created it with Intellicom. You can define the ambient background independently. I also own watchmaker, but unfortunately cannot specify the background for ambient mode there....unless someone tells me how to do that...I contacted the developers but never heard back. Maybe if several SW3 owners raise their voice we get that feature in watchmaker (which otherwise is a great tool).....

Invert it! Getring more white on ambient uses more battery.

Just add a square shape, enlarge it to fill the screen, move it to the bottom, make it whatever color you want* and set it to display when dimmed only. There's your ambient mode background.
*As MickeZzz has pointed out, although you can set the color to whatever you want, it will probably be displayed as one of four shades of gray (white, light gray, dark gray or black) in ambient mode. But the point remains that you can use a white background in ambient mode.

Aren't we talking about two different things here? The transflective screen doesn't require power to be readable in all but the dimmest light; that's true. But it's still not like an e-ink display, which can continue to display an image after power is disconnected. Doesn't every non-black pixel on the screen draw some power, even in ambient mode? Maybe the drain is small enough to be insignificant, but I don't think it's zero.
Please correct me if I'm wrong about this!

No. The Sony one is a transflective LCD. LCD use the least power when displaying white. Black requires LCDs to draw power to change polarity to filter out the backlight...hope that clarifies things.

I made a simple test in watchmaker to show the difference between bright and dimmed screen. I simply added two pictures in watchmaker and put the display mode to always on the pictures that I used.
In dimmed it seems to only display four different gray colors.

I'm not trying to dispute you, but I am trying to grasp this, especially since finding an earlier thread here, in which it's pointed out that the unpowered state of the display is, in fact, black. That would seem to suggest that black uses less power, but I realize it's not necessarily that simple. Do you know of any references that explain this?

I of course could be wrong with respect to the LCD in the SW3, I am only repeating what I have read about LCD a long time ago....
Best is you try for yourself - I have not noticed any significant difference (clearly not a scientific study) and I like the contrast better when the background is white.

Thanks. I've experimented some, too, but haven't noticed a significant difference. Your info may very well be correct, of course.

Just got my S9, but why the screen tend to be more yellow ?

Honesly, i don't expect the screen to be yellowish like that, but it is a bit yellowish only if i view it 90 degrees directly. If i view it from the side, the screen shift to blueish colour
Your guide is so useful since i am a new Samsung user, thanks

What phone are you coming from and what other electronic screens do you have around? The S9 is calibrated to 65K (see color temperature) and can appear yellowish if you are used to other screens that defaults to higher color temperature (including most iPhones/iPads). In that scenario there is nothing wrong with the screen and your eyes will get used to the new white pretty quickly.
On the other hand if your screen appears severely yellow compared to other Galaxy S9s' (e.g. check store models) then you probably should 1) get yours replaced from where you bought it, or 2) contact Samsung tech support.

Thanks for your reply, i come from Xiaomi Mi4i, it is cheaper phone by a large margin, but i don't know why the white seems nicer. Oh and i have another question , when i tilt the screen to the side, the white switch to blueish colour and it seems nicer than staring at the phone on 90 degrees, is that sAMOLED thingies ?

As to your latter question, yes that is an AMOLED thing. As to the first, do this simple test: Go to a room with no direct sunlight and no other electronical screens, where you can just look at the phone's screen without distraction. Use the phone for 10 minutes or so @50%+ brightness as you normally would, without worrying about 90 degree tilting. Do your eyes see the whie as yellow? Or have your eye adjusted to the new screen and white now looks white? If the latter, then your screen is likely just fine.
If you want to see what yellow-white looks like, try "Blue Light Filter." That thing does turn the screen yellow. (maybe you have it enabled now and that is why you are seeing yellow? )
---------- Post added at 03:00 AM ---------- Previous post was at 02:38 AM ----------
I have no first-hand experience with the Mi4i, but judging from what I can see in videos its color temperature is at least at 7500K, meaning it has blue-ish white.

hi im having the same problem with my s9 brought it yesterday and youtube videos look horrible discolor yellowish

had that issue with my first S8+. compare it with store models to check. my replacement was much better. now I have the S9, and it's definitely not yellowish. it's such a good white balance actually. so if you're not happy with it, exchange it while you can.

Thanks for all of the reply appreciate it, i check to the store and... turns out it is the same white as mine, still like the bluish white on my former phone. Compared to the note series, the note has better white. I tried to change the screen settings to cool, but it appear greenish. @lopri Thanks for the research on Youtube, respect for the additional research

I already calibrate the screen to cool, to overcome the greenish, i turn down the red and green color, now it is better but still can't resist my old phone blue-ish white.
When watching video on youtube it turns orange-ish, it might be because the video enhancer <- Now this is the problem

Before i got the phone, i have an impression that it would have a very great display... , but now it feels -- only good, but not overwhelmingly great like the review said
"· Record small Shifts in Brightness and Color with Viewing Angle, including White."
http://www.displaymate.com/Galaxy_S9_ShootOut_1s.htm

Adjust the display settings. Put display warmth to the highest then reduce red and green to a quarter.

it's possible the store display also has the same issue. mine is bluish white. I went through the same thing as you with my former S8+, in that even changing settings to cool, didn't make much difference. the replacement I got after confirmed that it was the display itself.

Yep, comparing the S9 and S8 side by side the S9 has a yellow tinted screen. The whites aren't as clear even after adjusting the colour settings.

Color saturation & accuracy

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the Xiaomi Mi A3's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!

I think Xiaomi Mi A3's display is over saturated, so colors appear much deeper than they really are. It looks good but not that accurate.

The colours are super-saturated and that's a bad thing. You'll notice it when you put a phone next to it and open same picture on both phones.
This really affects you if you post images on social media very often

So, is there a way to desaturate the colours? And by how many % to make the phone show the real colours?

Stock ROM has no native option to calibrate colours. You can install any custom ROM that has the option. I use Evolution X. It has a live display option where you can calibrate the display manually.
RED 83
GREEN 88
BLUE 100
The above values makes the screen look so much better, with much more accurate colours. Images from GCam now look a lot better.
If anybody has a better option or different values that work better, please let me know.

I used these values:
RED 83
GREEN 85
BLUE 85
Setting blue to 100 made my screen more bluish which was looking strange to me, these settings works fine for me.

Is puts me in a tough position. am really Confused i have been just thinking to be active on Insta.
Now if we are not seeing real colors on A3 what's the Fix for that?
Also any know what color Combination iPhone Uses?
Edit: After Browsing a Lot there are some users claim that the saturation is Not that high some are saying it is. Different people different comment :/
Can anyone Put Side by Side? amoled to amoled to see if there is something high or not?

I think you got used to IPS, in my opinion A3 screen has good color reproduction; I had many Samsung phones in my hand, so I got used to AMOLED color saturation; it would be way better if A3 supported sRGB profile though, while I don't think it is bad, it could be better.

There's a sRGB profile mode in Developer Settings
