Auto WB issue! Video Link showing dynamic changing in light sources: http://www.youtube.com/watch?v=0F0x1wkt5EU
This ones to all you SGS2 owners...
Today whilst takin' pics of my son, i noticed whilst pointing the camera down at my cream coloured carpet a pink hue was clearly visible in the centre of the shot. I took a snap and the hue was on definitely there... this was during the day time with only ambient light from my large bay windows...
slowly panning up across the room towards the window it seems to fade away, but directly at the light surface its unmissable...
I double checked the shot on my partners DHD, her shot was completely pink, very poor camera!!
Anyone elses S2 suffering from this? a quick google search shows this has also been an issue on other handsets such as the Nexus One and Samsung Focus...
Cheers,
Dickie
This is very important.
Can you make some photos and upload it?
if someone more have the classic tint pink of cheap cameras like other HTCs I am going to cancel my order inmediately.
Here are some untouched Macro shots taken in my backyard in fading light with the Galaxy S II, was a bit windy so the flowers kept moving:

I don't know of any sansung Focus.
Can anyone shoot to white walls or cloudy sky?
It is the faster way to see if the camera have the pink tint.

The shot! 8mp default settings

just to add, this has been the only time ive noticed this issue, shots taken across the room show no visible signs of this, just the straight shot...
tbh, with the quality of all the other shots ive taken, its not a deal breaker for me, this phone still blows away any other ive used, and i don't find blank white walls/carpets interesting enough to take photos of...
Dickie
That sure looks like something I read about some HTC phone a while back. I'll need to check my phone to see. I wonder if it's software or hardware related.
after some testing i believe this is a software issue, specifically with the AUTO White Balance setting, as i point it to the cloudy sky out the window it looks perfect and when switched to incandescent it goes away!!
like i said before, i don't make a habit of shooting my carpet or my white walls very often!
Dickie
EDIT: when switched to Daylight mode, it also goes away, although it makes the carpet look orange for obvious reasons... Definitely a White Balance issue, the lighting and colour of the carpet requires the correct setting as opposed to the Auto mode, outside or with good lighting the Auto setting is fine! as far as i'm concerned, panic over! lol

That it isn't a white balance issue, it is a hardware problem. HTC got the same problems on a lot of devices before, and they tried to hide it tweaking the colors, but that doesnt solve the real problem.
If I were you I will return the phone for another one.

then why when i switch to the correct WB setting for the lighting i'm in does the issue disappear?? the issue only arrises in Auto mode under certain lighting conditions. just took a white sheet outside on Auto - No issue!
Dickie
Maybe in a non-auto mode they know the color temperature that software will apply to the image and then they can tweak the pink tint of the image, but with an auto mode that changes dinamically the color grade they cant adjust the pink tint.
I really dont know, but all of the pink tints problems in all other phones are hardware related issues, I don't know why this is going to be different.
i get exactly what you are saying, but i'm only going by what i'm working out on my device...
at the end of the day, like i said before, its not a deal breaker for me, and ive not had a single issue with it in other lighting conditions...
Also, ive just walked around my room allowing the camera to adjust dynamically, and it does disappear!! i have a standing lamp on, a small window on the opposite wall, and the large bay window at the front of the room, the pink hue is not permanent and is just the Auto WB not being perfect.
Its even visible on video, so i'll upload a vid of the pink disappearing as i walk around the room and the light changes dynamically! Auto WB issue for sure!!

A pink hue like you describe usually means infrared contamination, and happens on any camera to varying degree. Some black clothing in direct sunlight suffers the most.

Regards, Matt
I'm just uploading a video to Youtube 720p - WB AUTO
You can clearly see the pink hue fading in and out as the phone auto adjusts to the varying lighting in my home, namely Incandescent light fittings, Fluorecent light fittings and daylight outside.
If i set the camera to a setting for one of those lighting conditions specifically, there is no issue in said condition.
I will update this post when its uploaded with the link - THIS IS NOT A PERMANENT HUE CAUSED BY HARDWARE - ITS SOFTWARE STRUGGLING WITH THE LIGHTING CONDITION!! - phew!!
Dickie
EDIT: the hue becomes very apparent after pointing the camera and any of the light sources directly then quickly moving to a white surface, it then gradually adjusts away...

not sure its the same buddy, it appears in the centre of the image and fades out, i'm 100% certain that this issue is WB/lighting condition related, 10mins and the link will be up if your interested...

I can't agree more there, you should have seen the same shot on the Desire HD, the carpet was entirely pink!! not just a spot in the middle..
Dickie
BTW I just checked my phone and observed the same situation as described by Dickie. After checking for myself I'm certain it's software related. They may need to tweak their auto white balance algorithm.
Please see link above or in OP

Hi,
I just got my i9100, but when I adjust the screen brightness to 0-20%,
the white color will become yellow tint obviously.
Does anyone have the same problem??
or it just happens on my i9100 ???
If it is common, any apps can fix it??
Please help.
Thanks.
Mine is whites are pure white at any angle even at the lowest brightness.
Can anybody else see the yellow tint, if they can it must be a faulty display or maybe you need a firmware upgrade, I dont know.
Hi.
Good luck reading this:

It could be a defective screen. There are some settings that effect the color temperature of the screen. Play with those to see if it helps.
Under Settings>Display>Background Effect, see what's checked and play with the different choices to see if it helps.
Under Settings>Display, see if Auto adjust screen power is checked. Toggle it back and forth and see what that does.
If it still yellow, exchange the phone. If anything, whites tend to run toward a blueish not yellow tint.

I think s/he's saying its the entire screen. That's been reported a few times. Sadly, there seems to be big variations in the color temperatures of the screen from phone to phone.

yes, that is the entire screen, not just part / a section of it.....
the color tone become quite yellow for the whole screen when the brightness is set to 0-20%, but when I set it to >20% brightness, seems there is no such problem.
I think the quality of Samsung screen is very various ....>.<
So i better to exchange for another one?

You should know that it may even be worse...
Do you have the possibility to get another phone for comparison?
I'm returning a SG2 because of it's low brightness and slightly over the top blue hue from viewing angles.
I compared it to my SG2 and it's solid whites from all viewing angles and twice the brightness of the faulty one on the lowest brightness setting.
Checked the settings, made no difference. Compare to a number of SG2, and then you'll know if your phone has a problem with its display.
Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

It's not backlit is the point.
Correct me if im wrong here but amoled is, by design, not backlit.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )
Sent from my GT-I9300 using xda premium
It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
Hey guys,
I havent seen a thread related to display issues. In 2 german Forums I found threads about various issues. From Color fade, to overall greenish tint or flickering screens.
Sadly I am very picky with display stuff and my Display isnt perfect either. I mostly use relatively low brigthness settings (around 30-40%) and on dark mode especially the settings menu has a color fade from dark grey to dark blue. This cant be seen on any other color.
Its easy to see in a dark room, the brighter the room the lesser you will notice.
To easier check: use telegram, with its blueish theme its definitely way stronger fading there...
For a phone thats 649€ in germany thats unacceptable for me. My P5 has a slight warmish but perfectly even colored display and thats what I expect from a P6.
What about you? Can anyone check their display if thats a common issue?
Hi,
i have the same issue, also a device from germany.
Even when booting when everything is white, I always have multiple changes between white and blue in the display.
I'm at work, I try to take a picture when I get home.
Please do, Id really be intersted. Sadly we cant do anything about it...
Anybody have the green ish tint on a black screen issue? Seen a few of those floating around as well...
Similar issues with my screen, also from Germany.
My first OLED screen had been with the Galaxy Note 1 and I hated it for its issues. Always bought devices with LCD screens afterwards.
The Pixel 6 is my first OLED phone since and it is having pretty much the same issues my Note had 10 years ago
Great phone so far (Android is still a bit buggy), but the display is quite a disappointment for me personally, at least for brightness levels below ~50%...
Is it just me or are most of these issues regarding the display coming from Germany? Please can people state what country the device was purchased from if they have this issue
Wow @Abnovitas thats really really bad. Sadly till now everyone seems to be from Germany...
I just finished chatting with Google's support.
They are going to replace the phone, but I'm still waiting for their email with instructions.
But first they walked me through some superficial settings (disabling Dark Mode and some accessibility stuff, like Color Inversion...) and then tried to talk it off as a normal property of OLED displays, which I didn't accept to this extent. But hey, that's probably just Google's policy.
Let's see if this was just bad luck in the OLED lottery.
For me its too difficult to take a picture with dark screen. The color change is slightly less than the picture from @man1acc
But i have problems with white color, it is light grey and i have green stripes on white, this is also very very difficult to make a picture.
Here you can see it a bit, but in real life it is much stronger
This is how my display looks like. Quite disappointing, Google has the same problems for years. But the phone itself is very well built, so maybe I will keep it. Bought the phone in Germany.
I have some rainbow effect which is mostly noticeable on white backgrounds. Hard to capture but found it is quite noticeable with an external light source. In this case my monitor. Anyone else have this or more importantly for a RMA, don't have it?
Pixel 6 when on a black background the right side of the display has a green tint shadow effect kinda worrying as it's not present on the left side and seems to only appear on darker backgrounds like when pull notification tab down or in a app (like xda) with black background very noticeable , or is this just standard now for Oled displays it's not the first phone I've noticed this over the years just curious if any pixel 6 owners see similar or should I get it exchange ? Added pic not sure if shows that well though

Not normal. Each pixel is controlled individually.
It maybe hardware or firmware.
Sounds like the display control matrix wasn't designed properly or is defective.

Unfortunately not true. If it's an issue with the display, a screenshot should never show it. But it can be visible when a picture of it is taken.
My Pixel 6 (right) was bought first day from the Google Store. I'm in the USA. It has a very strong dirty red tint at the bottom and a garish green at the top. Easily visible at 60-70% brightness and lower. Here it is compared to my Pixel 4a (left), shot on my 3a. Haven't had uniformity issues this bad since my OG Pixel (which got replaced).
Waited to chat with a support rep for an hour, chatted for another hour, and have an RMA device ordered and on the way.
Maybe are cross to dark side lol
That was a joke id never cross to the dark side lol and tint only seems visible when in certain dark mode apps and not actually navigating around the phone xda app is worse lol so don't think hardware issue tbh

My bad too, it wasn't worded as concise as it could have been.
who of you all has the problem with the green rainbow effect on a white background?
The mk III series was infamous for that.
The screen has a green tint in general, the white balance isn't perfectly D65. I still need to calibrate the white point. But there's no additional tint when I turn the brightness all the way down.
EDIT: After messing with the white balance I can see why they made the factory white balance so green. There is a serious bug and tinting the whole screen green hides the problem. Full thread detailing the problem here.
Not on mine
there's quite a difference between standard mode an creator mode. The former is more "cold" so with lower back light it looks like grey/blue but it is not a tint, just a dim colour
Pixel 4 had the green tint issue. If I recall correctly, it was related to the high refresh rate.
I do. It's super annoying. Aside from generally having a green tint, it's pretty bad at low brightness. It's very distracting
@zpk787 i had the issue, but it seems to have gone away after tweeking the white balance settings.
I have my phone set to standard mode with auto creator mode on for image quality, and then try your white balance to the attached image.

That's pretty interesting, thanks. I want to buy the 10 IV - skipped on the 10 III due to the screen issues, but there's nothing better on the market anyway and my current phone is way too old now so I'll just have to deal with it. Zenfone 9 is interesting, but it's gonna suffer from the same battery/heat issues as all sd 8 phones.
