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!

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.
Hey all, I had my g tab in my bag in a case in my locker for a couple of weeks. I pulled it out today to mess with it, and all of the true black colors have this Matrix-like green appearance to them. It's not any particular pixels that have become stuck, it's the way the device displays the true blacks. I tried all the market apps for pixels, and the colors work just fine, however, when the black and red come up, the green fuzzy pixels are displayed for a few seconds, and then become corrected. I'm not really sure what to do. I was going to take the back off and check for disconnected wires, etc, but thought I should ask xda first.
Thanks

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
I'v noticed a burn in signs somewhere in the middle of the screen (later I'll take a photo), its looks like a little shadow, darker...
Seen it only when I used RGB screens...
There is something to do (without replacing the screen)?
I'v heard about 2 options, donno how much its safe or will effect:
1. Using Jscreenfix - most for stuck pixels (its not the situation) but maybe it will do something after running few hours
2. Use blank white screen for few hours while the phone is on.
some says with full brightness, some says with low brightness, some says it will burn in the screen and will cause more damage....
Do you have any experiance with these 'methods' or any other tips to get it fix or halfix?
Thanks!
Are you using a non-oem battery? I order one from eBay (yes, I know ugh) and it was a snug fit and caused dark spots on the screen from the pressure.
Mine has a dark spot too, right in the middle of the screen. Looks almost like a shadow. I noticed it the first day I purchased the phone, within 2 minutes of first turning it on so its not burn-in. Its more noticeable for me on white screens like the google search page. I seem to recall one of the many cell phone models I've owned also having this problem. Maybe EVO?
Personally it doesn't bother me but I could see how it would drive others nuts.
I can personally vouch for the jscreenfix when you have issues with stuck pixels, however i dont think it will do anything for a burn in or dead pixel. I had a cluster of 4 or 5 pixels on an old blackberry of mine get stuck and played that jscreenfix for hour or two and it brought them back. But like I said I don't see that helping with a burn in though, if that is your issue.
Here's a picture of this burn-in, bad quality but can't miss the 'shadow' ...
@jrebo - I'm using the original motorola's battery.
Any chance it will 'fix itself' or there is nothing to do?
What about the option of using a white blank screen on with low/high brightness ? will it make it worst or its possible help?
Thanks!
I have a white spot in the middle of my screen and I've been using the oem battery.
Sent from my MB855 using xda premium
Why these dark spots / clouds appears anyway?
Seems like its happening at lots of smartphones...
I have a Nexus One which have a top notification/status bar burn in - maybe because it was on the stock rom with the white bg and set to be shown all the time.
But here its looks different, as you mention - cloud / smoke / dark spots...
Still not sure if keeping the phone on with full white BG will do the job or will **** it up more.... also not sure what brightness should use with this white bg...high or low...
@jrebo - about the replacement battery you bought, after how much time using this non-oem battery you've notice these dark spots ?
I'm considering to buy another battery from ebay (there is no other place here to buy oem batteries for photon) seems like there are some 'OEM' batteris (HF5X) out there with tag price of ~10$, not sure if its real or knockoff and what problem could it cause...
screen burn in can not occure on lcd and plasma displays since there is no phosphorous layer that the colors are being shot through... however there is something similar but its not permanent... pixels of other colors are not releasing there charge so they end up not going back to their neutral state. To cure this issue you get any one of the apps out there that run your screen through random colors every so often or leave the phone off and with no battery for a few days that will get rid of the immage permanence that you see. if that area on your screen is showing a cloud that does not match your current wallpaper than there is some other issue going on. and to cure that i have no clue lol
Hello, I own a i9100 and I have some burn-ins at the top of the screen that replicate some buttons of a browser or something, and some burn-ins at the bottom as well. I have read that leaving overnight an app that's constantly switching colours, with full brightness, could help a bit on that. I also read that leaving a blank screen (white image) on the same conditions (overnight, full brightness) would help as well. My question is, how true these both things are? I don't want to end with a bigger problem than the one I currently have. The burn-ins are most viewable at Blue, Red, and Black screen colors.(like if I put a background with one of those colors on it)
Never had any of these on my S2,but from my experience with the galaxy s plus,these tricks won't work.None will to be honest.It's permanent.This shows how immature amoled technology is.Learn to live with it or replace the screen if that bothers you much.
what a sign you got there...
Lucky you. Mine is not THAT noticeable if you're using it normally, but as soon as you open something with a plain color on it, the burn in shows itself on all its glory. So right now you can't tell if leaving the white image all the night or the thing switching colors will damage my screen more?
mwehehe
Well,back then when I tried every method you described above on my i9001,I didn't noticed any improvement nor any further damage.Even after running those for 10h+.So I assume it's safe.Can't say the same for the S2 though,have no problems with it.
