Hello
I'm new to android and just bought my s3 so forgive me if it's a stupid question
Whenever I watch a movie, there are two or three black spots. I feel like they are dead pixels. It doesn't show up on a white background nor on my ics inspired background but now I notice it a lot during a movie especially if it's a dark colored movie(darkness and all). Are these dead pixels? Is there a display app which I can use to display pure different colors and find out?
Thanks in advance

Spots? If what you are describing look like smears on the screen then no, I think this is an unfortunate defect with oled devices when black is viewed in really dark environments. My phone (not an s3 but uses amoled) exhibits the same problem and my PS Vita shows it very prominently.
A dead pixels is just a pixel (pretty much a dot on the screen) that is stuck in 1 color no matter what's being displayed onscreen.
There's a test screen, just dial *#0*#
However the black spots on dark background when your screen is on minimum brightness (e.g. in darkened rooms) are well-known issues plaguing AMOLED.
There are several threads around here describing them and their possible cause, and at least one developer has announced working on a screen tweak solving this and other typical AMOLED issues.
Yeah it's only noticeable on dark backgrounds with low brightness. I downloaded display tester and ran the dead pixel test and the smears were only noticeable if I looked super hard during a black background, not in blue or red or yellow nor gray. So no dead pixels right ?
Also thank you so much !

If you didn't notice any stuck dots, then your phone is good. As for the smears, pretty much everyone has them. I guess you have to be extremely lucky not to have them (that, or you just haven't noticed them yet so it doesn't bother you). The software solution pointed out above sounds interesting though. Will be watching that
About Dead/Stuck pixel on OLED Device Display
I have a S3 GT-9300 that I use daily, the other day I dropped it on a hard surface and a single shiny green stuck pixel appeared on the bottom left corner of the display, it was a bit of an eye sore really, But I'll share my simple FIX if its a related problem like mine was
I thought if the drop caused it, then a related solution may fix it, so I simple activated display and went to the home page.
then I turned the display facing my palm and held the device carefully at the top end and slapped it several times hard into the palm of my hand where the pixel problem area was. then stuck pixel went away...
I hope this works for you too :good:
Just bought a S3 weeks ago. I thought AMOLED display can go completely off when displaying just pure black . I tested it out with a full screen black picture. The display isn't going fully black it seemed like the display was ON with mild lighting. But the strange thing that I observed are some black spots(or random shapes) during this test. PLEASE REFER THE ATTACHED PICTURE TO GET A ROUGH IDEA OF WHAT I"M TRYING TO SAY. Is this showing something wrong about the display. What's your suggestion?
My suggestion is you search for the many other exact same posts before posting a new one, it's normal to see uneven black in low light.
I've noticed that my screen is rather yellow than my iPad or Xperia Z3C. Does anyone else have a yellow tint on their display?
In response to my dissatisfaction with the nexus 9's quality control (ie. light bleed issues) I've gone through 5-6 devices by means of in store exchanges, most of which have been 32 GB models. One device in specific, a 32GB White, i noted as having particularly noticeable yellow hue's. I had it for about 20 minutes before swapping, and compared it next to another device. Not only did the screen seem yellowed, but the displays output seemed to have diminished image quality when comparing to another N9 W32. I'm curious if this device has screen from multiple sources...

Several comments about this in the General thread. People are seeing with and without yellow tint.
EDIT:
I just tried my first N9 (white 32GB, October build) and yellow tint is on it--it looks "dull" next to my N7 FHD. It's going back due to a bent frame, but the tint would make me return it. I'll try one more.
Including here a couple of test images you can use to check for the Gluegate screen issue.
Test1.jpg -- Display this image with the brightness at full ina a dark room and check for green hues on the side
Test2.jpg - This image contains a combination of gray and really dark gray patterns which you can use to verify if its a gluegate issue or an oled uniformity quality issue on rendering certain colors. Display this image with the phone at full brightness in a dark room and try to swipe/move the image and see if the the green light also bleeds on the image dark bars.
Preferably download the images first and preview it fullscreen with your gallery/image viewer app.
Post your results.
Glue gate test
Hi,
Here are some screenshot of my display, with picture posted by you at 100% back-light. On other full black pics there is no problem but in test 1 pic. I can see some green light. What is your opinion. The device is an mate 20 pro lya-l29 with LG display.
I realy apreciate your reply.

I will let you think about it for a minute why it might be pointless to screenshot your phone when looking at display uniformity issues.

My bad.
You are right, I figured out just after I made the post. I have already post an answer, with some pics of the screen.
Here are some pics made with other phone to the screen

Some green light appears only on the pics posted by you. Any other black background for different display test apps stay complete black at different back-light levels.
I don't know what to do (to return the phone ore not?)
I have tried.
I have tried test1. Jpg
Result: there is green around the screen. At both sides and top and bottom.
Test2. Jpg
Result: the green is only visible in the light gray but not in the dark grey color.
What can you say? Thanks.

LG or boe?
LG sir.
Is the result of my phone gluegate or oled uniformity? Thanks
All this is too much hyped up i guess.
Lets not assume or generalise. There are huge number of batches and too many variations to pass such judgement

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.
Your screenshot isn't showing it so neither should the display!

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

Lol, read what I said again
At any rate... that's a dud.
Just for giggles and kicks, see if lowering the refresh rate effects that.

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?
