Hi,
now I have replaced my HTC TITAN by a new one, because the first device had a big and good visible dead pixel batch (2x2 pixles). But the new device has again some scattered dead pixles in the upper 1/3 of the display. They are only visible with a full black screeen, full brightness and a really dark ambience (I've used the Display Test App from Marketplace). The pixles appear as very small green dots on the display, maybe you need a magnifying glass. They are not visible on a white, green, blue or red background, only on black. Can anyone confirm these green pixles or do I have to replace my device again?

I just checked my titan with display test, it is perfect, you should get another replacement
Sent from my htc titan using XDA Windows Phone 7 App
hmm... Just seen, that this problem might be on other S-LCD-Displays, too. That's not a TITAN specific problem. I think there are only a few subpixels not working properly. I try to get another device -.-
Hope there is one left in the store I bought it, the have ordered ten devices and got only two...
Good luck! I am also a Titan owner, and so far, I dont have any dead pixels. I will keep an eye on it though!
Hi,
thank you for keeping an eye on it.
There are rather subpixles, which are not working. My girlfriend's Mozart has the same problem, but it jas only one red subpixle which is not working. Broken subpixles are hard to see, so if they don't bother me, I will keep my TITAN for now.

Same dead pixel with my titan too
Hi @zyclop
I brght HTC titan yesterday and same case is with me also. There are two minute dead pixel (you can say quarter dead pixel bcz they are too minute) and visible only in black background as green color. Any possible solution for it?
PS : I am fine with it as far as it remains two .. Could any one confirm if there is any chances for it to get multiplied in near future?
hi...ive checked my titan too...no dead pixel so far...try to become a replacement phone again....on contract they must replace it!!
also Titan owner now dead pix in here

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,
Today I've noticed a little white spot only visible under white/light colors background.
This picture isn't very clear (it is much more visibile than it seems) but I think it gives an idea.
Any one with the same problem? My phone never fell, doesn't have a single scratch and I always carry it inside the leather case.
Since I bought it through expansys do I have to send it back to them or can I go directly to an official repair center here in Portugal ?
I have the same, in similar(or the same) place. It is just slightly brighter spot.
Also ordered it from Expansys, but I am not going to send it back for replacement now. Do not want to loose my Leo for few weeks, I just love this phone
I have a similar white spot on my screen too. It wasn't present when I bought it. I can't understand what generated it.
I Too
I had the same problem. I bring my phone to service. They replace touch display with new one (I have 2 year warranty ).
I have the same problem. Sent it back to seller and now waiting for almost 4 weeks for repairs.
fortunately i have no that white spot...
Same problem here, sent it direct to HTC and they replaced the screen.
it also happened to me.
i had that problem, the only difference is i know where i got it from. i was sitting on a seat and the phone was put under some pressure and the screen stuck to itself thats the only way i can describe it. then it poped back out and left that strange white mark where it had stuck to itself, so thats a lesson to me (and you) do not under any circumstances have your phone in your pocket when sitting down. i had it repaired under warrenty and every things ok now, i make sure i dont pressure the screen at all now!!
Have a look at this thread (in which there is another as well):
http://forum.xda-developers.com/showthread.php?p=5668097
i had the same problem. just got it back after i brought it in and they replaced the screen. i didn't even begin to try anything myself. now it'd perfect again.
good luck!
cheers, ftrippie
I have a white spot to, right in the middle of the screen, and its the backlight that comes thru a lite more. Nothing that bothers me though since it's not really a defect - unless you don't want it to be, of course.
I sent my HD2 to the service because of the white spot....They told me it will take between 3-10days (I suppose it is the standard response).
Now let's wait....
I had a thread about this too. Very annoying so I emailed HTC and they told me to send it to a service centre for repair.
The problem is that I bought mine on Ebay and after they have the serial number they've told me it was bought in Czech republic so it has to be sent there.
I don't fancy doing that really - what bloody difference does it make which centre it goes to? ALL of these phones are still under warrantee so it shouldn't matter!!
Mine was assembled in Czech republic too but this is happening for all HD2 sold here. I will call Monday to check if they should replace the screen here or they have to send it there.
Today I've got back my HD2 from service after 12days.
They changed the screen and made me a rom update to 1.66.479.2.
Im having the same problem, the CPU is causing it. when you have "overheated" your phone, you can see it. I'm having a very cleary seeable rectangle in the screen. currently im E-mailing with HTC Support for Replacing the screen, or the whole phone!
This is exactly the issue I has, white blurry patches started appearing on my screen, with one in particular very prominent. I re-flashed the network firmware off the memory card, removing the HSPL and returned it to O2 for repair. I got it back 8 days later with a brand new screen.

You clearly have a different issue if you think that.
I had my screen replaced due to this problem & now only 2 months after I have the same problem and getting progressivly worse. Not Happy.
I am lost without my phone, it was hard enough the first time, waiting ages as they didn't have any screens in stock!! nevermind the thought of having to send it off again for a second time!!!
Really bloody annoying but my new screen is starting to develop the same issue. As I said above I had my previous screen replaced because of this a few months back and now I can see some more appearing. I can only assume HTC use bad quality LCDs because I have a 2g iPhone which is nearly 3 years old and it has never suffered with this and hasn't been treated any different than my Leo.
I'm not amused but I will send it back again to be repaired, using sub-standard components will cost them more than me.
White Spot visible on light backgrounds
Same here - refer attached.
Have made background darker to highlight this white spot.
The white spot resembles a 'feathered effect' as opposed to a 'solid spot'.
Red circle shows actual white spot on screen (may not be visible when viewing from a monitor / notebook), hence my attached image with darkened area.
It is only visible on light backgrounds.
Just to mention, I sent in my HD2 to LEAF South Africa yesterday May 13 2010, who completed the repair the same day!!!
LEAF really are superb in South Africa and a credit to HTC.
Thank you Wayne Parkinson of LEAF SA who took care of the details (as always), and their dedicated Support/Repair Team who did the rest.
Beat that HTC Worldwide
My sympathies to those experiencing delays.
Just bring your device to South Africa.
(No wonder the FIFA World Cup was awarded to our neck of the woods!)
I have a similar issue only that its only visible when viewing a bright screen and at a wide angle I see some light spot, its impossible to see it when viewing the screen directly. Can you tell me if it a spot on the screen or below it, or some deffect on the lcd. If its on the surface of the screen how do I safely try to remove it.
Hi everyone,
Yesterday I bought a White Sony Xperia S, in the evening I was playing with ita and saw 5 dead subpixels on a black background.
Today I went back to shop, I got a new one, but unfortunately this one has 2 dead subpixels on it
Can everyone put a black screen on and check whether you have blue dots on a black background? I just wanna know whether it's worth it to get an exchange again. Otherwise I just keep this one or have a refund, have to think about that.
Regards!

Take it back and exchange it for another, and before you leave the shop check to make sure that there are no dead subpixels.
Yea, I would just exchange again if i were you.
I have currently that eclipse background on my phone, and I don't see anything like that, so you probably just got two bad phones from the batch :/
The eclipse background is stock, so you could use that easily as a test before you leave the shop next time.
Hate that
I hope you got your new experia, i have had success in the past pushing down semi-hard on the area where the dead pixels are and doing circular motions over the dead pixel to revive it.

thats one of the hidden problems of xperia range.......i exchanged 4 x10's and 2 arc and when i tried arc s and three devices had one stuck pixels each .......
sony's replacement policy states that 2 dead/stuck pixels are acceptable

I changed my Ray with one stuck pixel, just root the phone, delete the camera.apk, unroot and go back in the shop saying "the camera is broken"... It worked ^^
If someone would kindly post a picture of a dead or stuck pixel as I personally have never seen one and don't know what the look like.
Thanks
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..
