On my TP, I have what looks to be just a single pixel towards the center that stays black all the time. However, when the screen is on but displaying all black, this little bugger shines bright white. I've tried running various apps that switch between colors and it doesn't seem to help.
Does this sound like something that can be fixed or that will go away, or does this point to a bad screen? I actually spoke with HP's support a while ago and they said they would be able to take it back under warranty and "fix" it (I assume I would get a different refurb back). I'm not sure now if I should just go that route -- I just hate to have to redo everything I have on it, plus I don't currently have any cracks in the plastic, etc.
Is there a stuck pixel program for android?
Yeah there are a few that I tried
https://market.android.com/details?id=com.htc.chris.blackspotdetect
and
https://market.android.com/details?id=uk.co.technicalmargaret.game.pixelfixer
I've left these running for a few hours a couple times, but no luck. I can't seem to figure out exactly when the pixel will shine white. It usually happens when the screen is black, but I tested it again and it's not all the time. I'm starting to think I'll either have to try to get it replaced or live with it.

I just noticed there that mine has one, it's not very noticable, I can only see it on a black background, but meh, I'm not tooooo pushed! Would obviously prefer if it was normal
If the pixel is black/grey, then the pixel is dead, and there is no reviving it unless you get a new screen.
If the pixel is green/red/blue/yellow then you can try to revive the pixel using a pixel fixer.
mine's a greeny sort of colour, will try fix it later XD
Turn you touchpad completely off and see if you can see this thing without it being on. I had to have my touchpad repaired because I had large chunks of dust between the glass and screen that displayed similar behaviour.
I recently noticed stuck/dead pixel on blue background on my S3. On white,green and red backgrounds it is not visible but on blue it is. Here are pictures,is it fixable?

Hard to say -- I would try to run one of the pixel fixer apps and see if that works. If the pixel is stuck on a color, it has a better chance of waking back up.

An S3? Those are not LCD, but organic LED screens. I don't think they can be brought back to life with the pixel fixer technique

Yesterday i bought a HTC Hero (my first one). When i turned it on and toke a good look at the starting screen (the one that says Hero, and HTC), i found a white pixel, probably dead or something. I went back to the store to get a new phone. This was not a problem at all and i got a new Hero. Now again, when i turned on the phone and toke a good look at the black screen, i also found 2 pixels with a other wierd problem:
The pixels also turned out white when i looked at them in a specifica angle. Just to be clear, i am watching on a black screen (starting screen). If you look at the screen and not in a specific angle i cant spot the pixels directly, but when i tilt over the phone slightly they show up and are 2 little white dots.
After i found out i downloaded the Detect Dead Pixel app. This app can create a black screen, the same screen as the home screen. When i use this app to spot the pixels again they are way less visible than on the home screen... I can spot 1 of them a little bit if i look at the screen in a certain angle and i can see a little dot, but i cant see them that good as on the home screen. They are not visible on other colors, only black.
I really dont know what to do with the phone now ... does anyone know what this is? im a bit concerned. Thanks!
After a bit more research on my phone i firugred that the dots really arent that visible. Maybe its just dust under the screen? When i put on a black screen using some kind of Android app i can not spot them. If the pixel is lazy or dead it should be clearly visible on a black screen right? for the lazy one then.
Anyway, i spotted a other problem on a black screen:
A brighter spot on the top part of the screen (like someone is pressing on it a little bit). Is this a problem ? im deciding if i should return the phone again..
Well its entirely upto you mate - i dont know what contract you've taken out but you may have that phone for 2 years. If your not entirely happy with it i'd take it back while you still can.
Issues with the screens rarely correct themselves.
My first Hero had around 10 dead pixels and i got it replaced as i wasn't happy with it. I now have one with a perfect screen and i'm really happy with it!
Well i just returned to the store and got another phone. This is the 3th one, and it still has problems, even more then the previous ones ....
On the boot screen there are about 10 very very tiny white wierd points visible ... im getting a bit frustrated here. What is this with all the screen problems ? :S
looks like they got a bad batch in your shop... have you considered powering up the phone while you are still in the store? might save you same time and way...

I have done that, but as i said, its only really visible in a dark room with screen brightness on 100%. I have checked the phone in the store and it just wasnt visible. When i checked the screen in a complete dark room i spotted the little things again. Looks more like dust to me =\
If your brightness is 100% you should see that one single pixel immediately.
Try making an image in paint (480*320) with a black background and a single white pixel. Open that image on your phone. The dead/lazy pixel should be just as bright as the one you drew.
Also the brighter spot is normal. It's called "backlight bleeding". Every lcd screen has this 'problem'.
They are not clearly visible, i think they are smaller then pixels, but they are countable on the bootup screen. When i tilt the screen them seem to change color (might just be dust). Green etc. I dont know what to think of it, come on. A wrong batch shouldn't be the problem if its dust, then its just a assamblation error. But 3 in a row?
I'm getting a bit pissed
It's dust or a fingerprint blocking a very small subpixel. Can't you just wipe it off? But I suspect very tiny scratches.
idk whether this is possible, but it might be dead subpixels. that would explain why they are smaller than a full pixel...
Does anyone know if that is possible? it sounds like a good explaination. Dead sub pixels could be the problem. They are smaller then pixels, but beg enough to be counted (i can count over 13). Little white dots on a 100% brightness black screen.
It must be dust, its a common question among hero owners. Most of the time the things they see is dust. It would be crazy if all new hero's have up to 10 or 13 dead pixels.
Ok well, here's what happened next:
I returned my phone again, god my cash back, bought a new one at a other store, SAME problem. Swapped it for a new one again, same problem!
Got my money back and i completely changed my mind of buying a Hero.
It is not dust. Its a perfect white dot, and definately some kind of pixel issue.
To bad..
Are you sure you're not being pixel-paranoid?
When reading all of this it sounds mostly like small dust particles under the screen. And looking at the number of phones you have tried, chances are you also got one with a real dead pixel (hot pixel, always on).
But I also think you are obsessed about it. My phone also have one dust thingy somewhere which I found just like you did (pixel tester, black screen). Smaller than pixel and less bright though.
I never notice the thing under normal use, unless I really go searching for it with a black background.
So you might make it bigger than it really is and miss out on a really nice phone.
Then again, we all have our own quality standards and its good yours is a high one!
I have had a tiny dead pizel since I bought my phone. Only really see it on the bootscreen.
I was always more bother by the light you can see coming from under the keys at the bottom and near where the lcd meets the keys.
I also have 3 dead pixels but they aren't that irritating.
I also discovered them when booting up the phone, but for me, they are sea blue (all three)
Maybe it is 2nd hand stuff HTC uses on their phones?
i have about 7 or 8 dead pixels too. it doesn't bother me too much anymore... only notice it in a completly dark room on the boot up screen... probably a common problem with the lcd screen the hero uses
All Hero's have this, or will have it inevitably:
The screen does not connect fully; there is a rubber-border between the glass and the metal frame surrounding the screen.
Look from the right angle, and you can see that there is a small 1/10th mm opening. Dust will come through here, and it will get on the screen.
HTC will wipe it off free of charge of course.
It is NOT a dead pixel; these can be seen from any angle, although the color changes a little but because of the viewing angle.
Call HTC and say you have dust under your screen, they will fix it for you, free of charge.
Hi,
I have read a great deal about Super AMOLED plus screens having the best blacks because they physically dont turn on the backlight, saving power.
Now i have noticed, When viewing a black screen in the dark, there is actually a fair bit of light leaking through. even though it is "black light" (like on an LCD)
Can anyone else confirm this, or explain it?
Thanks
Its as black as black can be for me.

Perhaps the black wallpaper is not a pure black, instead it's a combination of colours to make it appear black.
I really can't see it in mine, but I've always wondered about this when looking for a black wallpaper. It's actually hard trying to find the darkest black using a PC, and wondered how you can really tell, as all black wallpapers would be a combination of colours.
I think it would be great for the power saving on the SAMOLED screens if you had an option to select "no" wallpaper or colour, so the background would automatically not actually turn on, using zero power.
This would guarantee you are using the purest BLACK and ultimately ZERO power on the background of your SAMOLED screen.
How does my theory sound
No Wallpaper and Colors apps in the Market will do a pure black wallpaper.
Use a microscope. lol
Actually it is a nice way to do it. Go to hobby town or somewhere and get a cheapy 10.00 microscope and you can look at the actual pixels. Not only can it help you here, but its always rather interesting to see.
Also, keep in mind that even when black, it still does have a little power in it, even if very minute, and still allows light a little bit, even if just in very very very very very minute amounts.
Ohh! Someone else has this to!
What happens is if you look at a pure black in the dark yolu will see almost white / grey areas, and it is not the image it is the same for everything that is 100% black , but is less noticible when something else in on the display, I also have a dark spot in the center of mine when it's on min brightness, Might send to Samsung, Or ask Vodafone they seemed to have a dodgy batch of phones.. this will be my 3rd
So I think it's a defect? The first phone I had didn't do this

Yeah, I already sent my first GS2 back for screen problems, I dont want to have to send it back again and live without it for another 3 weeks. Also, I have subsequently flashed custom roms, so I would prefer not to.
If it ends up breaking, I'll just get the screen replaced when it happens.
Instal lcd test from market. When you see black,its like the screen is off...try it...

Excellent, thanks for the tip, it's as black as I'm going to get ;-)
This is my 2nd Evo 4g LTE,( the first one had a defective digitizer/logic board), and i noticed it had 2 very small white/red/blue/green dots whenever i watched a video with letterbox, or any video. They flash different colors depending on the color of the screen, for example if my screen is mostly black the dot would be white, if the screen is a bunch of different colors the dot would be red, green, or blue. I tried rebooting, flashing new roms, and even going back to stock android, still nothing. I ran one of those stuck pixel apps for around 2 hours and one of the stuck pixels at the top of my screen is mostly gone, but the the one in the left middle is pretty persistant and never seems to leave. I assume they are stuck pixels because they change colors, flash, and only show up on videos,some apps, and my camera. If anyone has had any experience with stuck pixels on their phone or have even got rid of some, any tips would be much appreciated. it isnt too big of a problem to where i need to replace the phone AGAIN, but it just ruins movies/videos for me and is very annoying. THANKS!
Anyone else having this issue? When I switch to the dark mode it's obvious the black level from one corner to the other is not the same.
A black saturation test clearly shows the bottom row visible when the device is rotated one way and then not visible the other way.
Anyone else getting this? I'm going to ask for a replacement.

Damn, that's almost exactly the same.
I just got a full refund for mine as the shop I bought it from had no stock for a replacement. Another one on the way from another retailer, hoping the display is in better shape.
The quality control on these appears to be a bit crap.
OneUI uses dark grey on the Tab S and Note10... There are many, if not infinite variations of grey that approach black. I do art, so it's easy to notice that #000000 was substituted.
SD_black is black, OneUI simply has a dark mode. Also black cannot be uneven on OLED, because black refers to an off state.

You're just splitting hairs.
Black can appear uneven on defective OLED displays. If you use a black saturation or black clipping test you can clearly see with the tablet or phone rotated one way that the bottom row is barely visible (which is normal), but rotate it another way and suddenly they're all clearly visible, they're only visible because that part of display is defective.
I have OneUI on my phone as well, there is no visible banding and black/gray levels (whatever you want to call them) are uniform. If you're seeing any variation then you got a bad display and you should get it replaced.
Similar here. But mainly noticeable in very low brightness especially with night mode on
With which app do you test it?

Display tester, first match on the play store. Find the black saturation test
Or you can use something like the below, loads of similar tests available on the Play Store or online.
https://www.avforums.com/threads/ho...el-on-oled.2204710/#lg=thread-2204710&slide=0
Replacement arrived today and it's even worse than the first one, instead of one corner it's right down the centre of the display.
Also found an easier way to highlight the issue, using the image tester select the burn in test and move all the sliders to the left, this should give you black. Then slowly move the green slider over, you'll notice some parts of the display become green when the rest remains black, at least up-to a certain point. Took the image below in good lighting.
The Amoled lottery. I had to go through many returns before I got a Tab S3 that didn't have unacceptable display uniformity and things don't seem to have improved a lot since then.
I guess that it's cheaper for Samsung to deal with the returns of customers who notice and care about this than simply having better quality control in the first place. Reviewers of course get cherry-picked samples so the quality of the display can be praised to high heaven.
Really makes me think twice about even considering upgrading though...

Is your display like that for every image with that gray scale? Or is it just elements of the UI settings, dialer, contacts etc when you have dark mode enabled?

you can even see it on on xda black theme.
But since this is a common issue maybe manufacturing level, I rather leave it like this, because I do not want to end up with an even worse one.

hi
hours ago i found that when a blank tab is opened in samsung internet (i am using dark mode in system as well as the samsung browser) i could see the uneven black on the screen. i tried to rotate it but still the uneven black was there on the left and right hand sides in landscape mode, and on the top and bottom after i rotated it. so it should not be the ui or one ui problem
i remembered i have read this post so i revisit it and found many of you have the same problem. when i bought this tablet i have check via *#0*# to see how the black was and it's perfect. i also checked with *#0*# before replying to this post and the black was perfect too!
i am too wondering what could be the problem. i think it could be the dark mode which does not use true black (pixel off) in fact

Yeah, It's not the dark mode, this issue effects everything.
If it was just One UI I could ignore it, but sadly it's not. Essentially you have different parts of the display clipping at different black levels, even the sections that are relatively good still look patchy.
Samsung screwed us all but it's OK because it's not a popular product so nobody cares, prime example of how useless reviewers are as well because none of them picked up on it, cherry picked parts from Samsung probably.

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
