Hey guy,
So a friend of mine had a strange problem with his htc desire
Last night while reading some stuff his displayed color changed,
first thing i noticed was the rly pinkish tint, everything was slightly pink Oo
noticed this Thread but that wasnt the issue here
hope u guys can see sth, it seems its only 8bit color depth, 256 color
since some pictures are getting some rly ugly "blocks" in it
Well my question is, is the display broken? should he get a new one?
can a new rom fix this problem?
Thanks in advance
Kemo~
Try resetting brightness to auto.
we did that already, the pink tint increases with lower brightness
we also did a hardreset of the phone nothing changed
When i take a picture with ddms.bat it looks normal
its rly strange :/
Is it an LCD (slcd) or AMOLED Desire?
Its an amoled

The AMOLED screen on the Desire has more red pixels (not quite right, but the easiest way to put it) then blue or green. What this means, is that the screen of the Desire is inherently tinted red. This is mainly more noticeable when the brightness is at low level as the color spectrum on a screen uses light to adjust the colors. With less light, the red has more of a bleed through effect and becomes noticeable. I really don't notice it unless it is at VERY low light or I have the screen with a white background and next to a device with another high end type of display such as the iPhone 4 or the Galaxy S which don't have the bleed through effect... well, with red anyways... they have the effect with blue.
Strange... I've seen oled displays look like that after only a year but that's in very rare cases. They wear out but not just like that if it happened almost insantly.
Did you look at the display just when it happened, did the other colors just sort of fade away or did they go in a snap?
it happend in an instant, an no i didnt have a look at it when it happend
but it seems the display is broken
well he gonna replace it, lucky he still has warranty =)
Thanks guys for the replies
Cheers

Anyone else notice this when the screen dims or you lower the brightness pretty low? It looks fine at full brightness.
I'm on my 2nd phone, swapped my last one due to a camera issue. My first phone didn't have this tint
I've heard OLED-based displays have inconsistent while balance, especially at varying brightnesses. I use Chainfire3D's nightmode to set a custom color. Totally worth it.
So I've had my Galaxy Nexus for a few days and for the most part love it. One thing that surprises me is that the screen... The screen's quality was one of the main reasons I bought the phone, but whenever the screen is mostly white or a light color, it just looks... bad. Like it isn't one uniform color, it's almost a grid. The lower the screen brightness, the worse it is.
I'm just wondering if this is a fluke or if everyone's phone is like this, and this is just an effect of the pentile display or something.

I'm seeing it as well, my old phone's TFT screen looks far better at low brightness.
The nexus looks grainy due to the pentile as well as a brownish tint at lowest setting.
I've very worried about this. I'm the type that COULDN'T STAND the pentile on the Razr, like, return day 1 type of can't stand it.
Is the nexus considerably better as far as the grainy blocky pentile? I heard the resolution makes it a lot better. Is this true?

I haven't seen Razr in person, but Bionic was terrible.
The Nexus' isn't anywhere near like that but for someone OCD like me, I've found it slightly annoying - but not enough to not recommend it based on the screen.
Like Nexus S, Google choose too warm colours also for GN. Anyone can notice the yellowish effect/tint in white background even with brightness set to max level. So dont worry our screens are fine... f#...n google has made this choise.
Supercurio said today that he will try to fix that and also boost up the brightness.... also paul will give it a try.
Well done Google for ruining the best display out there
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

Hallo friends, i read lot of about problem with this kind of display( pentile matrix)
I have vertical and horizontal banding too. But this one is something what is bothering me much more.

That's nothing to do with the Pentile Matrix! Definitely a defective screen, return it to the store and ask for a warranty replacement. The 'banding' is more to do with the AMOLED screen technology rather than the Pentile, as it was present on my SGS2, but is generally only visible under certain conditions (background colour/brightness).
Regards.
Is it visible on colors other than grey?
Sure, on blue background too,sometimes on white.(poarws photo with blue background) It depends on brightness.
More visible at white background with high brightnes.
More visible at blue and grey background with lower brightnes.
It does have to do with the Amoled technology, but I doubt it's a defective display. You can try to exchange it to see if it really is defective or not.
I have some vertical and horizontal banding only with lowest brightness at the white background.
With maximum brightness no lines or whatever
AMOLED has a few imperfections here and there, so it's not surprising. But if it's bothering you too much exchange it for another one, it could have less prevalent issues.
Just performed a test using screen test app my screen looks great.

How high is brightness with test screen
Mine is fine too but 60 percent and more.But this one issue bother me pernament ( no matter if 30 or 70 percent brightnes)
Tuesday iam going for a new piece, hope that will not be affected worse than mine
Try viewing those shades of grey on your phones, it's usually the most problematic color. Use a low brightness setting (around 25%) at a dim environment.
This exists on all OLED screens. Its the exact same on my Nexus S. It has nothing to do with pentile matrix, but OLED.

Yes i had nexus one galaxy s galaxy s II so i can compare,nothing like that before that.
50-60 percent of brightnes
I have the Galaxy Note and it has the same panel as the Galaxy Nexus albeit at 1280x800 instead of the Nexus's 1280x720. (Super AMOLED HD with Pentile sub-pixel arrangement)
My screen is great. The whites are brighter than they were on the Nexus. The Nexus displayed whites with a yellowish tint especially on low brightness. Plus I can't seen any banding on the screen and I have tested it on White, Red, Blue, Green and Grey backgrounds.
Im getting a new Galaxy Nexus in a couple of days. Since this unit is from a later batch I hope that there is no banding on the screen too.
Funny, I have a similar issue to Delarock's on my Galaxy S2, manufacturing date is 19th of October. I'm still thinking whether to replace it or not since since it's only visible on dark'ish grey, I couldn't replicate it on lighter greys, white, or any other color at various brightness settings.

the same on lowest brightness...
so I always set up my phone to the hightest brightness
Hard for me to get a good photo but you can see the same problem on my NEXUS S screen. Its just a characteristic of OLED displays in general.

Really similar to the screen on my new Galaxy Nexus. I didnt notice the diagonal right away but that is certainly more significant. My screen a rosy hue in the bottom half and especially the lower left.
I'd love to see a similar picture of someone who says that their screen doesn't have it.
(Click for 100% crop)
So are some of these screens defective? Or is it really just the nature of the beast?
How does one tell what manufacturing date their device was made to? Would I be able to go to a store and exchange for a datecode that shows no banding issues?
I am having the same issue ... another thing I notice is weird issues with the camera while in a dark room. If I have my camera on in a low light room, I get this weird "dancing" of black blotches in the really dark areas of that room.
I like all solid black wall paper, I find the fastest easiest way to get it is to turn off the camera flash, put my finger over the lense and take a pic. Worked for every other phone I have but the GNex. I get a weird blotchy image ... now I am on GNex#3 (other 2 I returned for different issues) and I have noticed this camera thing on #1 and now #3. With the first one I assumed this was normal ... but after going from the second one to the third I see a HUGE difference in screens. With phone #2 I was able to do the phone/black wallpaper with no weird distortion. Now the really strange thing is that that same pic taken with the second phone (that displyed pure black on that device) shows up blotchy on device 3.
Hope this makes sense to someone lol cuz reading it back I sound crazy.
I just hope the folks at the Verizon store don't give me a hard time trying to get another one!
