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.
So i have a bright (white) pixel on the screen...
It's really visible on BLACK and little visible on BLUE background ( not visible on Red or Green background)
the pixel's visibility does change when i change the screen brightness
so is this a dead or stuck pixel.... how fixable is it?
Sounds like a dead pixel.
Cant be fixed. If there is only one then they wont replace it. You're stuck with it(no pun intended).

I've got one as well but is only really visible above 50% brightness on a dark background. Unfortunately the pixel died about a week after I got my S but I've managed to ignore it most of the time. Having such a high pixel density helps a lot.

Please don't post Q&A in the general section.
If any thing you have to say can end in ?????
Then it belongs in the Q&A section.

yeah i have one too, visible on white screens but also on most of the other colors.
They said that they fix such things only from the 4th pixel
Too bad, I have been through 4 Xperia S phones. Two from yellow tint, one bad battery and my latest which has no issues. None of them have had a dead pixel, so I am surprised to see so many.

Is exactly the same to me, in the top of status bar (touch firmware 6, ABAE and 12w16). I hope to be the first and last ...
On my Xperia U I have one green stuck pixel. It amazes me the Sony quality control check. This is my third SXU. First one 4-5 stuck pixels, second one totaly dead and then this one with stuck pixel again. Sony service center and retailer didn't want to acknowledge the complaint. They told me that one or two defective pixels is acceptable.
as far as all my reading goes, the dead/stuck pixels are always claimed by manufacturers that these are "within specifications" whenever there's 7 or less on screens (TV, monitor)and 4 or less on mobiles (as their screens are small).
on my experience on TV though, you can forget about dead/stuck pixels if there's 7 or less. the most important thing to test is the backlight bleeding, check leakage of light on a black screen (that is screen is on displaying a black image). that is more important than few pixels which you will just neglect in time. the backlight bleeds, this you can never forgive.
now for mobiles, its very rare they would have backlight bleeds. so there, we can focus on the pixels. i think this would be more noticeable on large screen phones (4 inch up) or low pixels per inch density. from hereon, its best to test the phone before paying for it, display a black image for backlight bleed check, then colored and white screens to check on dead/stuck pixel. don't ever pay until you're satisfied. its very hard to return/refund/argue when you paid already and noticed the bad thing. unless it happens after you leave the store. so again, its best to thoroughly check it before paying, and of course fully warrantied.
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:
Hi,
I just received a new S3, and I'm noticing what I would call a couple of dead pixels: on a white screen (but also red & green, on blue it is not noticeable/ I cannot judge) at any brightness, there are two distincs points (I would say, pixels) that remains black.
When magnifying the zone with a lens, I can notice the defect is circular with the size of few pixels (<10) with lower luminosity then the rest of the display, with the center emitting no light.
Anyone with the same experience? How this is evolving with time: starts working? worsen?
One pixel is towards the border and just the second (in the center) bothers, but effect is very small and noticeable only when you know it is there.
I took the phone on Amazon, so with great flexibility for returning it, but I got it on .de (and I'm living in .fr) because of the great price (359€) and it is a bit annoying returning it.
Thanks for the feedbacks

I ve has 4 S3's, all brand new, 2 out of the 4 had dead pixels.
the one i currently have is dead pixel free, i cannot stand a dead pixel.

Well, that's certainly one of a kind....
So noob, just send it back. No biggie It's Samsung's fault for having appalling build quality. So just go into the store and scream your head off till you get a new one, or preferably an s4 for inconveniences.
I just noticed a dead pixel in the bottom right corner of my HTC Rezound. I've had it for over a year, and it just showed up, is that normal?
Is there any way to fix a dead pixel?

i have one when i got the phone lol. its not noticeable at all unless i go on the internet on my phone and look at full black image full screened
but you can get dead pixels from dropping your phone and something hits the screen, which can happen with monitors and tv's ect... dead pixels are permanent, only a screen replacement can fix this
have you dropped it recently? idk if the screen can just start dieing in random spots though lol
You may be able to unstick a pixel by rapidly cycling it on and off. I think there are some apps in the market that will do that. It doesn't always, or even usually work, but it's worth a shot.
hate to say this....but with the high dpi the rezound has, its probably more than one pixel if you can see it. I have used the dead pixel fixer app on the market and its nice when you need to set the screen all black or another solid color.
