My first unit head a stuck green pixel. Swapped it out and got a handset with zero stuck or dead pixels.
The new handset does have a hot pixel on the camera sensor, however, but I might just live with that since it only shows up in low light shots and is located at the edge of the photo.
No dead pixels. No stuck pixels.

Hot pixels tend to disappear through time anyways same with stuck pixels. The one we should be worried about are the real dead pixels.
People tend to mistook stuck pixels with dead pixels.
Dead Pixels = Always black in color
Stuck Pixels = usually not the same color as the other pixels(Sometimes it's changing colors rapidly)
But they just fix themselves through time.
I had a dead pixel on my developer edition :-/ sending it back.

Really? I didn't know that hot pixels (camera sensor) can fix themselves. I was always under the impression that these get "mapped out" at the factory, but then other hot pixels can develop after the fact. I do recall that my Nikon D300 developed a hot pixel, however I haven't checked to see if it's gone.

Only had the phone for a few weeks. I see one minor blue dead pixel. Kinda of hard to notice but my OCD caught it.
Anyone else experience dead pixels?
So because I have one does that mean that more will come? :O
Guess I'm the only one?
I've had one dead pixel but I don't even notice it anymore. Maybe that pixel was reborn lol.
If you're lucky you might be able to return it and get a replacement.
blue blue pixel isn't a deal pixel but a stuck pixel

Download jscteenfix from the market. It may help get your pixel unstuck. Good luck!

Sweet; I'll try it out.
I don't have any dead pixels, but I have a minor screen defect that is similar to what a stuck pixel looks like, but it is only visible from certain angles and under certain lighting conditions, so I decided to live with it. It kind of looks like the distortion that happens when a drop of water gets on a screen, but only about the size of a pixel.
Hi! I have a question about should I be worried or not. Phone is two days old, and I have noticed, when I turn off the display, one pixel shows for a microsecond (it just lights up for a sec) on a black screen. I taught that may be some "dead" pixel, but examining the display with dead pixel app, there is none. Just that one little pixel when turning off display.
Should I be worried?
Thnx!
I would say no. Unless you're a paranoid and you think your phone could explode, you don't have to worry about it if you still have your warranty though, you can ask for a replacement
Try a couple different dead pixel apps, and if it passes on multiple apps then you have nothing to worry about...

Thnx! No dead pixels on any app. I noticed that sometimes on my boyfriends sgs+ also multiple pixels light up on turning the display off. So it must be that samoled reacts that way sometimes...
Hello everybody.
As said in the title, my question is :
With Amoled, is it possible to have a lit dead pixel ?
Thank you for your answers.
Have you tested on your phone for dead pixels ? or just speculating ?

Dead pixel means permanently unlit.
Stuck pixel means permanently lit.
is there any way to fix stuck pixels?

By running an app such as Pixel Curer or Dead Pixel Detect and Fix located here:
https://market.android.com/details?id=com.xllusion.app.pixelcurer&feature=related_apps
Or
https://market.android.com/details?id=com.htc.chris.blackspotdetect&feature=also_installed
Though removing the dead/stuck pixels is not guaranteed it's worth a try running the above programs.
The only other alternative is buying a new screen.
Best of luck.

I personally would not risk it....bandings are not as bad as dead pixels.
Dead pixels, sure. But I wouldn't expect an AMOLED screen to be able to have a stuck pixel, in the traditional sense. It it had a pixel that stayed on, I would expect that to be an electrical issue, via a short somehow causing a pixel to get charge when it shouldn't. Stuck pixels on LCD screens are essentially a mechanical issue. The apps that fix them do so by switching those pixels rapidly until they get "unstuck". There is no mechanical action to an AMOLED screen. If a display somehow had a pixel that was always lit, I don't see how any app could fix that.

Banding is generally a software issue, not a hardware issue.

Hi,
I have noticed that there are some stuck pixels on my HTC One screen by accident when using camera in the dark.
Has anyone else noticed stuck pixels on their device?
A 'stuck pixel' as opposed to 'dead pixel' is a permanently lit pixel (white in my case, clearly visible on black background) on a LCD display.

I thought I had two stuck pixels, but it seems to be a slight flaw in the glue between the glass and screen. For example, if the brightness is set to auto so that it dims in a dark room, I cannot see any dots. But if the brightness is high, and then view in a dim room with a black screen displayed, I see two dots. Those dots change in brightness depending on the angle I hold the phone. You may have real stuck pixels, but I just wanted to mention this weird phenomena that can look like them.
I have a very similar thing to what Jonstatt described. Sounds a lot like stuck pixels to me. On my third handset for this reason.
I'm considering contacting Phones4U with that issue. There should not be any display defects on a brand new, quality handset.
I did my third exchange this morning and finally got a flawless unit. Well worth it, and I would agree that there shouldn't be any pixels stuck on a brand new handset, especially if you are going to have it for 2 years!

yea i got a stuck one as well. It's in the last row on the far far left side of the phone so not noticeable but I know it's there ...
Shouldn't get this on a phone this expensive.
On the other hand my as well as many others on the forum's S3's screens were pretty horrible so i guess it's hard to get a perfect one.
Where are your pixels located ? is it enough to warrant a return ? thing is i got mine from phones4u in the UK but i'm in France now so wondering if I should send it back to HTC ?
edit: DAMNNNN just did the black picture test, so now I have at least 5 stuck pixels, wtf???
Pixel Fixer
there's an app in Play Store by the name of Pixel Fixer or something like that. There are a few free versions you could try identify if there is any dead pixels and it'll try to fix them. It worked for my old Motorola Defy, it might work for the One.
EDIT: sorry, it fixes stuck pixels...dead pixels are, well, basically dead...can't do anything about those.

Dear god not again.
This was same thing had happened with One X launch. I had to return 4 devices back to HTC to get the one without any dead pixels, or screen separation issue back then.
This time I have Developer edition on pre-order. If this one has dead pixels, I am simply going to return it and wont bother again. I am not going through the same thing I went with One X again in my life.
Na pixel fixing apps don't work for me
Man this is a real shame, might wait a bit for better versions to come and return this one to HTC even though i don't want to, such a great device.
This should not be happening on a high end phone like this. Gaps, dead pixels and hissing noise...
I have 7 dead pixels. This is crap. Wondering now as lots of people have this issue if HTC are cutting corners to make extra profits.

I have a small trapezium of stuck pixels, show up on green and white as bright, right on the edge on the left, about 3cm from the top of the screen. I'd say, given the pixel density on this screen, mine is a cluster of at least 4.
I debated internally about it for a week as it wasn't that noticeable, and the phone is otherwise free of the other common defects, tried pixel fixer apps as I'm certain it wasn't there on first turn-on, but have contacted the Three store who will replace. Here's hoping my 3rd (technically 4th) HTC One will be my perfect one.
I will be checking it in store for bulges, pixels, hissing, camera and so on haha!
So sad. Also keep pressing 3 dot menu when trying to press spacebar is so annoying.
Mine is going back and getting s4. Wanted a change and regret it.
Sent from my HTC One using xda premium
I've got a single dead pixel on the RHS about 2/3 of the way up the screen (in portrait mode). Can't decide whether to live with it or send back to affordablemofiles for replacement. Pixel fixing apps had no effect.
Spent ages in phones4u picking out a phone with no dead pixels, took three box openings.
Now found I have two bright stuck pixels! It's going back!
With one I bought online & returned previously, 4/4 have had pixel issues.

I haven't noticed any stuck/dead pixels. But that's not to say there aren't any.

Hey guys, I just got a replacement of my One (previous one had capacitative buttons' light leaking out of the rightmost bottom part). I just noticed that I have a stuck pixel in here (white) and but not black (which means it's dead, right?). So I was thinking to get a replacement again, but I'm afraid that the other one may have more stuck / dead pixels than this one, because I've read people complaining about multiple pixel problems. So, what do you guys say? Should I get a replacement or just wait for the pixel to un-stuck itself?
The only thing that irks me is that it's in the middle of the whole screen.
*BUMP*
Anyone?
There's a few apps that help with stuck pixels, they just flash the screen multiple colors until the pixel fires correctly.
I had 3 stuck pixels when I got this phone but within a week they fixed themselves

I did use this app, the impact of the stuck pixel have seemed to be lowered (ran the app 3 times for 30 minutes) as compared to before. But it didn't vanish completely.
Ignore it... I had my HTC One for 2 months now and when I got it there was no stuck pixels... Then within the 2 months usage stuck pixel are popping out and just disappearing within days of ignoring it. Some last for weeks but they all eventually disappeared. I only have 1 stuck pixel now on my unit where somewhere within the 1st month it manage to produce up to 6 stuck pixels.
Wow. I was just thanking my stars a couple days ago that my One was perfect. No gaps in the corners, no dead pixels, no faulty camera, no nothing. But it bricked and now I'm gonna have to get a replacement. Hope my luck holds out.

Just for the clarification; was it a white pixel? And if you increase the brightness of the screen, the brightness of the stuck pixel also increases?
Yes it is white sometimes changing color constantly I know what stuck, hot and dead pixels are
And by the way it's not noticeable on lowest brightness so yeah it's visible only on high brightness

Thanks a bunch, you saved me from getting my second replacement. I was just clarifying my concept of stuck pixel, and not judging your knowledge.
Oh yeah, and what was the average period they got fixed by themselves? How many days / weeks?
Like I said it's random... Only those I've noticed is 4days, 9 days and the longest was I think 5 weeks I always noticed the 5 weeks because it seems like 2 pixels got stuck which is side by side to each other so it created a much brighter white. But it got fixed by itself in 5 weeks estimate. Not sure how it got fixed though probably the constant video playback(I'm an anime junky) or must have cured itself because I'm always setting brightness to the lowest level.
If pixel fixers which changes color everytime does indeed fix these issues then I'm pretty sure it got fixed because of the video playback... Watching anime videos for 4 hours a day sometimes 8 on weekends is an overkill for constant color shifts.

Did you ever try pixel fixer? And that anime stuff is very interesting (changing colors). I used pixel curer for like 80+ minutes on my phone but the pixel doesn't even change itself from white or I think I might not be able to notice as it is so small.
Thanks for all the help, I am limited to 8 thanks / day, so as soon as 24 hours pass on, I'll thank you for all your posts.

80minutes is nothing compared to mine... When I watch an anime you can compare it to running pixel fixer for 4 hours a day And like I said it get's fixed in days or even weeks.
So running 80minutes of pixel fixer is not even comparable to what I do on my phone
xperia e stuck piel
I recently got an xperia e on orange pay as you go from my local carphone warehouse. Last night i noticed a blue/white spot on the screen. After looking at the screen closely more smailer specs appear when you tilt the device around but this one stays visible throughout. They are especially visible in the dark but not so much in sunlight. Another thing to note is that it only appears on dark backgrounds e.g. black.
I have tried a stuck pixel fixer for about half an hour but to no avail.
Since its only a few days old i thought i could return it to carphone warehouse but dose anyone have experience of doing this. I know, because i got my phone on orange, that i can not just replace it for no reason. However i would like to know would they try to fob me off by saying that they can't see them or saying there needs to be more of them to warrant a return. There are a few other things i could say to get a return. For example the proximity sensor does not work in the diagnostics app and there is "no signal" at my house Its hard to get a picture of it otherwise i would've included one.
So really my question is should i try and return it (in the uk we have pretty strong consumer laws (the sale of goods act)) or should I just ignore it and run the flashing light show for longer.
Thanks
James
I though i had a white stuck pixel on my notification bar, i took a screen shot, and it appears on the image, so it appears it is part of the stock htc one wallpaper. :laugh:
