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

Lighter vertical line of pixels in landscape

Hello everyone, today I've noticed that on landscape mode my GN has a lighter and brighter vertical line of pixels on the left side, if I turn the phone on the left; if I turn the phone on the right it doesn't happen and everything is fine on both sides. It is really annoying me and I can't say if it is the first time it happens or this kind of issue has been always there. It can be noticed only with white or light backgrounds and in EVERY photo, if brightness is switched to max it is hard to see but with automatic or half brightness is pretty clear.
I tried to screenshot it but I'm afraid this is something hardware since it doesn't show on screenshot.
Anyone else with the same problem?

Is it green? I have a similar issue. I think it's a case of screen burn.

I think I have the same issue. Don't know if I should go and get a replacement. It also only shows on white background while browsing.
EDIT: The captured screenshot doesn't show this, so no point in uploading it.

Took it to assistance. It'll be back in 10 working days and since I don't have something not even similar to replace it I'm stuck with an old Sony Ericsson W205...what a nightmare!

At least you can replace it. I am from Israel and I bought the Gnex in the US directly from Google. I noticed this problem a day before I went on the flight so I didnt have much time to replace it. But it doesnt much bother me. I know that those Super AMOLED screen have too much problems... Just live with it right now.

i have the same issue right now.
For replacing the GNex i had to go in a samsung point or they come to my home for took it?

I have the exact same issue on my Galaxy Nexus. The same row of pixels (along the top-edge). It's not visible in portrait mode because the notification bar is black and the pixels are switched off.
Here's the kicker: since this afternoon, the row of pixels are switched on even when the background is black. They appear as a faint line and become brighter when there's a background image. I put the phone under a magnifying glass and there appear to be three such rows, not one. It could be the pentile matrix playing with my eyes since the pixels are too small to see even with a (low power) magnifying glass, but there's definitely more than one row.
Anyone else?

Can you post or link a picture? I mean under a magnifying glass, just to see how it looks like...ehm not sure if it is possible though

I am having the same problem on mine too. There are these streaks that runs across in landscape or portrait. it's more noticable in a grayish white background. It's very easy to see with a screen test app that shows one color on the whole screen. Lately, I also notice the very top and bottom line of pixels like would lit up brighter. For example, when i touch the context buttons at the bottom, bottom pixels of the buttom would lit up bright white.
Edit: clariification, it's the same lines of streaks if held in portrait, it would go across. when in landscape, the same streaks goes to to bottom.

I also have a lighter vertical line of pixels on the side of the screen when in landscape. The interesting thing, though, is that it is on the left, regardless of whether my phone is in landscape with the power button on the top or the button. either way it's on the left of the picture. So I don't think it's a hardware issue. More likely a calibration issue?
I also have horizontal banding of slightly different shades in portrait on grey/white backgrounds (eg: facebook app). These become harder to see the more brightness I turn up.

Yep, have it too...
Now I'm deciding whether to go to the Service Center....
Other than that small line, the phone is perfect so i guess i won't bother..

I got the entire screen replaced by Samsung Italy. 100% hardware issue

i have the same issue... but i think it is not "burn in", it is just a pixel line brighter than the rest, in my case it shows all the colors as it should, just brighter.

Strange...

A couple of weeks ago I noticed the topmost line of pixels of my Gnex is miscoloured or brighter than normal, and yet sometimes displays correctly, usually when black.

I noticed it's on the bottom too. Maybe some backlight problem or something... But sometimes it changes colour due to shades changing, it's like in half shades it's shining more and in other half it's darker. Like some software compensating. There's other colours, but blue looks differently.

HTC One M8 backlight bleeding problem?

I got my HTC One recently (last Friday) and it was a perfect phone! no problems whatsoever...
Yesterday i was playing with the phone with a colourful background wallpaper from HTC and i noticed light bleeding from the top (hold it in a angle and you can see a light bar shine through like this:
http://forums.androidcentral.com/at...een-issues-uploadfromtaptalk1367129491252.jpg
It isn't that big of a deal but for a phone that costs over 500 euro's here in my country.. you expect that it is build properly and backlight bleeding on a phone at this price!?
I compared 4 HTC's in the store and they all got the same problem

GPe dims the edges of the screen, so it's harder to notice if it's there. I haven't ran sense in a while so I can't tell either, but I can't notice this light bar effect on my phone either. So it may just be that batch of phones.

Got it in in my bottom right corner... very minimal though

Wow, that's massively anal lol.

mine was the whole top screen.. but it doesn't matter, that's just HTC right..? They're known for the screen bleeding, haha..

I've been having this issue on the bottom of the display. It makes the nav buttons look funny and full-screen content is washed out.

Here's mine. Italian H3g branded:

That light bleed above is probably a bit excessive bit you guys have to realize that all LCD screens are going to have some light bleed. You can usually make it less noticeable by using a lower brightness setting. If you are really anal about the slightest amount of bleed you should really be looking into phones with AMOLED displays. That said, if the light bleed is washing out the nav bar at reasonable brightness settings you should try to get it fixed or replaced.
My M8 has some bleed on the top left corner at normal brightness and I'll notice it across the entire top if I go full brightness in a dark room. At normal brightness it doesn't bother me at all.

With Extra Dark Screen, Light Coming From Right Side and Bottom Right Side?

So, when my tablet is on, but the screen is super dark (basically black) there is some faint light coming from the right side and toward the bottom right side).
Is this normal? What is this?

That is called light-bleed. Many LCD devices suffer from it. It's usually only apparent when the screen is black. I noticed mine when I first got my tablet(s) but you get used to it... and not many situations arise when your screen is full black, except for some extra dark video scenes (for me anyway)

Is it a defect? Is it normal? Do they all have it?

Screen Bleed?

Does anyone else have a little but of backlight bleeding on the bottom right of their 10?
Oddly enough it isn't visible on a black screen, only colors. Grey seems to be when it is most visible, such as the calculator app.

I think I might have a very slight amount of bleed. I never would have noticed it though unless I was looking for it.

Hmm, interesting. It's definitely not enough to warrant an exgange or anything in my opinion.
Still kind of annoying though.

Almost all LCD screens have some form of light bleed. My G4 has light bleed around the edges, if you're in a dark room with moderately high brightness. Not noticeable any other time.

I suppose I'm surprised only because the M8 that I had exhibited zero bleed.
Like I said before, not a huge deal, just a bit curious.

I just noticed some light bleed on the exact same spot: lower right corner. Is your display a Tianma by chance? Can it get worse over time? To be honest, I didn't notice any bleeding on the M8 or M9 either, so I'm a bit surprised as well.

Light bleed should not get worse over time.

Either I'm blind or I don't have any bleed.

I'm kind of dissapointed of HTC quality. All my android phones are/were HTC but I think that their quality is getting worser. Month ago I've decided to buy HTC A9, first unit had crackling earpiece. Replaced it and the second unit already had burned spots on the AMOLED. Then I've decided to spend some extra cash and replaced the second A9 with HTC 10. The first unit had 2mm white spot 1cm above the fingerprint scanner. The screen was also a bit dimmer and at full brightness the LCD grid was clearly visible. There was also a gap above the earpiece from where I was able to see the headphone jack internals, so probably a few rain drops and the phone is bye bye. The second HTC 10 have some gaps here and there but nothing major...they'll fill with dust and durt over time, so there will be no gaps .and yes the there is backlight bleed in the lower right corner also smaller amount bleeding on the entire lenght of the upper part of the screen. I've noticed the bleed right away when I was still at store, but honestly I have never seen LCD without even small amount of backlight bleedind and also I gave up on finding the perfect HTC A9 or HTC 10 , so I'm keeping the second one and I'll try to forget about the price paid.
....I don't think that matters, but yes mine display is Tianma.

same here, fa67 black, tianma 2 weeks old
whiteness on the lower right (it seems bigger in calc app), above home button, but gently pressing and holding between scanner-home button disappears that.
i think there is a small gap in the screen, but this annoys me

Neither here, I have a Tianma panel, but I am struggling to understand where the light is bleeding?
Front of my phone is black, so screen is up against front black bezel, where would it bleed to ?
any chance for a photo example?
