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.
What could be the cause of having none dead pixels and the day after my whole screen is filled with them.
It hasn't been in any situation that weight or pressure would harm the screen but for some reason i have those dead pixels all over the screen.
Any ideas ?
Anyone else had the same problem?
(it's away for repair now, i'll hope they fixed it)
u mean some bright pixel when in dark background? if is... mine too.. at 1st it doesn't have it. after i use a apps which is say maybe able to fix dp or lazy pixel... then i found that mine got more then 10 bright pixel... before that i dont have any...
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.
My solution to a stuck pixel
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*

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.
Hi, i've had my samsung s3 for about 20 months now nearly 2 years and so far so good.
however i have been reading that AMOLED screens eventually have dead pixels and ideally if you were to get them it's before the 2 year warranty window rather than just after.
My question is before you started to get the dead pixels and black spots on the screen did you find that it would go away for a bit then come back?
just now when i backed out of an app i noticed there was a big black mark dot on the screen.. larger than one pixel but maybe like 4-5 in a circle and also to the side of it a slightly discoloured pixels of red etc.. when i swiped through the windows where my apps were it all went away. was this just a glitch from what was showing on the app i was using (with black screen and red colours) or dead pixel potentially forming?
I have no idea what dead pixels look like when they're dying.. though i do know it's all black when they're dead.
is this most likely a glitch or have you guys who have had dead pixels before noticed something similar just before they died?
I've a Droid RAZR for 3+ years now. No issues with the display till now.
I think not all displays die like that..
Sent from my SM-N9005
I got a note 4 back in February but i noticed some dead pixels and the display is also very less saturated and contrast is very low. I replaced it still the replacement also has that dead pixels and less saturated screen.
Since i couldn't afford to wait again for replacement i decided to get to service centre.
I wanna know will i get my display replaced without any hassle and for free?
