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. ;-)

Yeah, I was exaggerating, but compared to how bad it was with the other one its crazy. Very less noticeable than my first one

Pink hue in white pictures

Is anyone else having a issue when they take photo's that in very bright white area's there is a bright pink color? It has now happened with two sets of pictures I have taken, One picture that has the sun in it actually has a dark pink dot right where the sun is... Is this a setting, common or should I take my phone back? the phone is only a couple days old

Lens flare? (Very common) but the colour is something like purple...
Can you show us a picture?

Bad "backlight" uniformity?

Hi all,
Had my Pixel for a few days now and noticed what I thought was a new gradient in the background of posts in the XDA labs app, I checked the screen using one of the grey test colours and found that I'm getting a dark cloud over the bottom right hand side of my screen. I tried taking a photo with my old phone (Moto X Pure) but the camera isn't good enough at low light for it to show up, I'll try and get a photo with my DSLR when I'm back from work later today. In the mean time some quick googling has shown it's very similar to the "Dirty Screen Effect" described here: http://www.rtings.com/tv/tests/picture-quality/gray-uniformity-dirty-screen-effect-dse
Had anyone else noticed this? Do you think Google would RMA it? I've not really been bothered by the blue shift on my device so I'm slightly concerned that I might end up with a worse replacement if I do send it back
Cheers
Michael

It's a tough call, you have to ask yourself if you can live with it or not. Does it show up a lot during normal usage? Or is it just with the XDA labs app and similar applications in a low light setting with your brightness turned to like 0-10%? Or if you can see it at all times regardless of brightness settings you can contact Google tell them of the screen issue and get a RMA. Check out the replacement and compare the blue shift to your current and see if it also has the same issue as your current device. If it's better in both regards send it back, if the blue shift is a bit worse on the one and you can tolerate it and it doesn't have the bad back light uniformity you could keep it. That's what I would do personally, best of luck!

Yes, I have a similar issue. My first device had severe blue tint at any angle and Google would not replace so I returned and and reordered. The second device had only slight blue tint and is not an issue but of course has the uneven grays. The right side of the screen is much darker and there is also a dark spot around the sim tray area on the left side. I sent Google pictures and they are sending a replacement. It's only noticable in low light, looks fine at higher brightness though.

Ah I didn't realize they sent you the replacement first. That makes it a much easier decision. I'll still try and add a photo of it in the OP later today but RMA seems like the best choice. It's noticeable at lower backlight brightness and since it's winter here in the UK now the auto-brightness often drops it down to a level where it is noticeable just in normal daily use.

I get a VERY slight hint of that on a dark gray background at 5-7% brightness in a totally dark room but other than that very specific condition it's uniform otherwise.

The photo as promised unedited straight out of the camera (USB C OTG is neat). It's not quite this bad in person, if you imagine the light grey is the same shade as the dark grey in this image and the dark grey as being almost black then you get the idea, but it does show the difference between the two and it is clearly visible with the naked eye in a dark room.

Woah! Holy crap that's pretty bad. I would RMA that bad boy right away.

Screen quality and uniformity

Hello,
Are you satisfied with the screen quality? Mine has a yellowish tint at the bottom.

I don't see a yellow tint

You mean like this?
https://www.reddit.com/r/Huawei/comments/9wqfrw/help_has_anyone_experienced_this_lcd_backlight/
If yes, then yeah I have that too :/
Not too thrilled about that

I have something similar bleed, but it's only visible a very low brightness, like very near to 1%, I'm using display tester app to see it, with auto brightness in dark room isn't obvious.
Regarding a yellow tint, I think that my bottom half display as a slight warm white, it depends of brightness and the room light, angle that I watch the screen.

Subtle purple edge tint in very low light? (S20+)

Anybody else noticing an extremely subtle light purple-ish haze on the edges of extremely low light photos - i.e. where the dark/black areas are in a low light photo around the edges?
It's subtle. It's a reach to see it at times. But this is an expensive phone, so I'm going to nitpick... It reminds me of the old issues with the HTC One M7 and some older Motorola devices, though on a much more subtle level. I'm probably crazy, but I know I'm seeing it at times.
Snapdragon S20+ here (Verizon variant)

Ok, so I realize it would've helped my first post with some photos and additional info. Please keep in mind, I love the camera on this phone 90% of the time, but this 10% is an issue that reminds me of the old days (per my first post). I have two sets of photos... First are the originals, uploaded, and added into Photoshop with a black "frame" to help you see the haze better. The second set is a photo from my iPhone of what those photos look like on my S20's screen. Reality lies somewhere in between the two. The second set over-emphasizes more than what I see on the screen, and the first set mutes it too much. These photos are night mode photos, which I realized after my first post helps to accentuate and show the issue.
Ultimately the problem seems to be how the software and/or sensor are handling the extremes when you have a bright light source as the focal point, and dark outer edges (again, reminiscent of oooold devices). Anyway, the photos are attached. Hopefully that help clarifies it a bit more. It's nitpicky, as there aren't many scenarios where this would come up. But it's a $1k+ phone... I feel like I'm allowed to be nitpicky.

Is it always on the left side of the phone screen? i.e. always on the top of the phone? or does it change to either side when you rotate the phone (could be on the top or bottom sides)? I have not observed this purple thint issue, but your third photo shows that it is extremely bad.

No, it's more pronounced on the left there due to the lighting in that situation. But if you look at the fourth picture you can see it's relatively even on both sides where things start to darken.

I'm not saying it's normal, I too suffered from the HTC M7 syndrome but in those specific photos, is the purple haze coming from a TV light on your left? Is there any tv screen running when you took the pictures?

No - no TV's on anywhere. The purple haze is coming from the especially dark areas.

Just checked on mine s20+ exynos, other than very minor green tint no issues, if i were you i would replace it asap - something isnt right

I bought an unlocked S20 (+ was too large for me anyway) and tested it last night in the exact same spot and exact same scenario, and very little haze at all with no purple. I can see what it's trying to do - it's trying to lighten up those darker areas, but for some reason on that S20+ it was making it purple-ish and just plane ugly. It doesn't look "great" on the regular S20, but it's at least not purple and clearly just trying to lighten it up. S20+ is already on its way back for the return.
