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

Hi all,
Has anybody else noticed a yellowish tint to their screen, especially when displaying lighter colours, white, light blue etc?
This only seems to be the case when looking directly at the screen. If I look at it from any sort of angle the yellow tint is not there.
Any info or confirmation that others are experiencing this too would be much appreciated. If this is a hardware issue then I will return my phone.
Thanks all

Sorry to bump this, but I assume the lack of replies means I'm alone with this issue?
Should I get my unit replaced or is this a software issue?
Thanks
Mine is quite yellow too against my S2. Decided it must be faulty and it's going back.
Going to stick to my S2 with Cyanogen as it's much better...
When I go into my settings screen it has a yellowish tint in the bottom half of the screen where the top half is black.
When I go into my app drawer the background is black as it should be.

The gradient in the settings background is a feature.

I have not noticed any yellow screen in the settings menu myself.
I have been reading that the Galaxy SII had similar yellow tint problems when released and that it was corrected with a software fix?
I'm more worried that this isn't a hardware fault more than anything, software faults don't worry me too much as I'm happy to wait for a fix...comes with the territory when owning a smartphone
Think I will be returning my handset, the yellow tint combined with the volume problem is doing my head in!
I have been watching a few you tube clips and i don't see much yellowish tint on theirs but then again it does go completely black in the app drawer.
It really doesnt faze me as much as the volume issue though.
is it a problem or a feature?
I don't really know what to say, but let me give you my 2 cents.
First, AMOLED screens are all different for some reason, and I can vouch for this as I replaced my Nexus one 9 times for power button and various other issues, and each time the color temperature was different. Some were warmer (with a red tint) while others were cooler (blue tint). If you swap it, you might get a better tint, maybe even white if you're lucky.
Second, the Nexus S also had a tint problem (yellow tint) just like yours. The two display models at my BestBuy both are VERY YELLOW compared to my HTC Sensation and look really bad, but it might be because their screens were ruined from being on for so long. There was a post on XDA in the Nexus S forums who said he swapped until he got a "white tint" but then Google actually updated the Nexus S with different Color Settings and totally washed out his screen, while yellow tinted ones actually got better. If Google releases a color patch, you might not like it, but I don't think they will after the backlash from the Nexus S one.
tl;dr Get it swapped, it's a hardware issue. Swap until you get one you like, you paid for it, you deserve it.
Oh geez here go again, i thought the yellow tint was going to die with the galaxy s ii, guess not, it's alive again on the galaxy nexus , i swapped my galaxy s ii because the yellow tint was too distracting, in low "backlight" the white looked yellow , the one i got is less yellow but the colors dont pop as much as on the first galaxys ii i had

You're going to want LCD if you want perfection, but you'll give up great blacks and thinness+battery life, not to mention the phone entirely.
Keep swapping, took my 9 tries but it was worth it for my Nexus One

I've got the same 'issue'. While I understand it is a feature, it really looks odd/very greyish, especially on auto brightness.
BTW I'm starting to like that yellow tint. It really is helpful when browsing the Internet, because it's more pleasant for the eye.

Got mine today. The yellow tint was the first thing I noticed. I know it's fixable, but it's annoying.

OMG, is it really as bad as in this video?
The Galaxy Nexus screen looks so yellow compared to iPhone 4S display
It looks like he has auto-brightness enabled on the Galaxy Nexus.. it looks yellower unless you turn up the brightness.
The whites on the iPhone 4 are ridiculously clean and white, no phone compares to it. The blacks on the Nexus are also ridiculous and no phone (except other Super AMOLED phones) compare to it.
Take your pick, better whites, better blacks. The iPhone screen is still tops, but it's small. I have an iPhone 4 and a Nexus (just sold a GS2).
If I compare the screens side by side, then yeah, the utter blinding white of the iPhone 4 makes the Nexus white look kind of eggshell white, just not as bright or crisp. But using the Nexus on it's own and it's fine, white looks white enough when not being compared to the iPhone. The colors on the nexus are much more vivid and true to life than on the iPhone.
Nexus also has crisper text than on the iPhone 4 believe it or not. There is no perfect screen, all have +'s and -'s, you just have to pick which +'s you like best. For me it was the insane resolution, size and color accuracy of the Nexus. It's plenty bright, just not plenty white when compared to the ifruit.

iPhone doesn't have Roboto
definately noticed the yellow tinge... bloody Samsung!
actually the yellow issue on the GN appears to be because of the colour profiles that have been set in a similar way to how google updated the nexus S and altered the colors.
in AMOLED screens overtime the colours actually fade and become less vibrant now blue usually goes first and is at a much faster rate than the other colours.
considering that this fading occurs perhaps they deliberatly make the colours a bit 'warmer' to offset the blue fade time.
this was also interesting:
"Color balance issues
Additionally, as the OLED material used to produce blue light degrades significantly more rapidly than the materials that produce other colors, blue light output will decrease relative to the other colors of light. This variation in the differential color output will change the color balance of the display and is much more noticeable than a decrease in overall luminance.[63] This can be partially avoided by adjusting colour balance but this may require advanced control circuits and interaction with the user, which is unacceptable for some users. In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors. More commonly, though, manufacturers optimize the size of the R, G and B subpixels to reduce the current density through the subpixel in order to equalize lifetime at full luminance. For example, a blue subpixel may be 100% larger than the green subpixel. The red subpixel may be 10% smaller than the green."
its quite possible that the tints that are experienced on oled devices are probably deliberate to offset the problems with oled technology.
So, anybody else have a chance to hold two E4GT's side by side? My wife and I are both trialing units, and mine has a much more pronounced bluish tint. I remember reading something about variability with Super AMOLED Plus screens, but the significance of the difference surprised me.
It's not that either one is so much better or worse, but they sure are different...

Settings>Display>Screen Mode. One of you could have messed with that setting. There are three basic settings that change the picture settings on the phone. Dynamic, Standard, and Movie.
I remember reading from someone who calibrates screen colors who tested this phone.
When new, screen has green tint as it ages it gets blue tint , movie setting has the most neutral colors.
My screen has green tint you only notice it when comparing another phone LCD or with HDMI on your tv
Edit I forgot I noticed my pictures have a green tint but that problem bad white balance ,compare a picture or the same screen with another good phone et4g has green tint in pictures too

Actually yes. My buddy has one too. Our screen settings are the same. Set with the same settings, and same wallpaper, his blacks are deeper and more defined and colors much robust. Both screens set to standard under display type

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.

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!

The apps like whatsapp and xda premium and fb for android all these apps have white background bt it looks off white in my phone?? I have a sgr I have compared both the devices in sgr it looks pure white than my note 2 n7100......
I m on stock Indian rooted odex firmware XXALJ3 4.1.1??? Is there any solutions for this? ? Not only pages I think white colour only looks off?? Anyone one else observed this?

If you are talking about yellowish tint of white colors, yes its a screen defect that samsung cant get rid of.
I also have that yellow tint as well as many people. You arent the only one. There are some people replaced their phones but no luck still there. It has something to do with amoled production.
Also you will realize that if yiu tilt the phone slightly and look at the screen from angles the whites and gray colors will look normal without tint. This obviously shows its a production thing.
There are other threads with same problem as yours that you can read. Just search...
It's a problem with amoled screens unfortunately. All of them have it unless a kernel is used to adjust the screen.
Have you tried disabling "Auto adjust screen tone" in the display options?

It has nothing to do with that....
It's normal man. LCDs have awful "grey" blacks, with brilliant whites. Samoleds have deep, rich blacks, and tinted whites.
