First of all, I'm going to throw out a quick FYI fact: The One carries a 1080p display on a 4.7inch screen. The sheer resolution of the display increases the chances of getting a dead or stuck pixel. The ~469 PPI on the One also means it'll be slightly more difficult to spot these defected pixels.
Definition of dead vs stuck pixels:
Dead: These pixels are black and only visble on a bright background (preferably a white one). These pixels remain unlit (no green/red/blue pixel lights up)
Stuck: These pixels are essentially stuck on either red, green or blue colors and can be spotted on a background that is any color but of that the pixel is (if the pixel is green, you should be able to see it in a red, blue, white, or black background). These probably stand out best on a black background.
It's generally viewed that stuck pixels have a higher chance of repair-ability through flashing colors (white, black, red, green, blue) in succession on the display through an app.
I just want to know how much these defects affect HTC One devices as HTC has had some pretty bad issues with dead/stuck pixels in the past.
I, myself, have a dead pixel (unlit -- black) on the bottom of the display (barely above the "u" in Beats Audio when you boot up the device). It isn't bothering me too much, but I'm weary as to whether I should keep my unit as this may diminish future resale value..
Do you guys have a dead or stuck pixel on your unit?
p.s I'm not sure whether this should go under the "general" section or "Q/A", but I'm not looking for a specific troubleshooting Q. If it needs to be moved, please report the post (or move it if you're a mod).

Mine stuck pixel is white-ish yellowish colour and can only be seen on a black background with the brightness quite high.
When I first got the phone however I didn't have this problem, so its happened over time, I have since sold the phone so I can get a 64GB version
I though i had a stuck white pixel on the notification bar at the top of the screen, after a bit of investigation it appears the stuck/white pixel is actually a defect in the stock wallpapers
can anybody else confirm this???
it look like jpeg compression has removed the stuck/pixel though you can still see the location.

I had one stuck (white) pixel but it disappeared after using a fixer a few times
the suspected white/stuck pixel still shows on the stock wallpaper, but as i said when i take a screen shot, it`s on the screen shot , so it`s a defect in the wallpaper.

You should use one of the dead/stuck pixel fix/detector apps from the play store, some free ones are good enough
I have used a dead fixel finder app, and no stuck/dead pixels show up on any color that i can see
It`s just strange the htc wallpaper has a defect that looks like a stuck white pixel.
thanks

Do you think HTC would replace a unit based on dead pixels, and how many would be the threshold?
I have 1 dead pixel visible on white background, but each time i have to search for it couple of seconds even if i know the location, so it is not so bad...
If a WHITE pixel only shows up on a BLACK background, is that a stuck pixel or a dead pixel?

I had a single dead pixel and T-Mobile replaced my device. Not sure about HTC's policy, but I'm sure it's similar.
sadly got some dead pixels, the shape of the outline of the moon, though only i notice it hehe, my brother wich is a freak in those things and he didnt notice
I plan to leave my bad pixel until just before the warranty is up then I'll get it replaced and sell a like new phone for the HTC Two lol
Thanks for the heads up about the "pixel fixer" apk. Looking at the images, my phone is defect free. Rock on!

I have sent mine for a replacement today because of the dead pixel and a small darker spot on the display. HTC support said they are replacing defective units(dead pixels) 30 days after buying. Hope my operator will give me another one in the next few days.

I was browsing through the gallery just now and noticed a dead pixel. Or what I thought was a dead pixel.
When swiping through the gallery, there is a picture of a pink flower, followed by a black and white photo of a man. The b&w photo is portrait. I had the phone in landscape mode.
In the black space in the top left, I noticed a red dead pixel. I swore and carried on swiping.
Next was a landscape picture of a dog, but I noticed as I continued swiping that the dead pixel was still there.
Next is a skater in portrait mode...and the dead pixel is gone!
I swipe back, it comes back.
Swipe forward, it's gone again.
Anyone else's do this? I had to do it in a dark room to notice.

This sounds like the dead pixel may be in the photo rather than the phone.
If you only get a dead pixel on specific photos, but cannot get the same result on any other screen on the phone, then it is probably the photo.
Take a photo so that the image is black (photo dark piece of cloth) if resulting picture has dead pixel, it is phone screen and you have a dead pixel, but one pixel should not cause too much problem.
With LCD screens, normally there is a percentage of pixels that can be faulty before it is classed as defective under warranty or sale of goods act.

if it was porn pictures, then the red dot is god's eye watching you
If you see a red pixel illuminated against what should be black, you could have a stuck subpixel. A "dead" pixel implies the inverse; a black pixel where there should be colour.
On the photo of the man in black&white, with the phone rotated landscape, there are black spaces either side of the photo as it was taken in portrait.
On my phone, these black spaces are pure black.
When you display a picture with colour that occupies the space of the pixel in question, you wont notice it. Each pixel has three smaller subpixels that make up the colour; a red, green, and blue one. When the stuck pixel's nextdoor neighbours switch on, you won't notice the problem. The problem is that this pixel won't turn off.
If you want to return the phone, I'd make your mind up and do so as soon as possible while you still can - but perhaps using the proximity sensor thing as the reason, as most manufacturers/shops won't accept dead/stuck pixels as a return reason unless theres several of them, or if they're right in the middle of the screen.
Best of luck mate.
I'm not sure if you're understanding me. It's actually ok, just not when looking at that particular photo! I'm just trying to understand why. It's fine everywhere else, just not on that photo. But its not the photo as it doesn't move with the photo when it swipe.

Yep - very strange. I think you have full rights to write HTC about this and ask for explanations.
Hey,I know apart from dead pixels,there are some other 'bad pixels' like colourful pixel(sorry,I translate it directly from Chinese,that's what we call them.There must be an English name.) and white pixel.Different kinds of bad pixels behave various from different colours of background.That's why you can see them in some situations while some you can't.We often test 'bad pixels' of screens of laptops with several colours of background when shopping.
Maybe you could give this a try as well: http://www.appbrain.com/app/com.jscreenfix.android

Hello all. I have a weird problem about some pixels on A501 screen: when the screen is on and the background is black, some of them will show "bright"... but not white, i'd say some sort of pale gold or very light brown, but again not white. With other backgrounds (red, blue, green, white) those pixels acts as normal, not being distinguishable from the others.
Is there something I could do? The issue is a lot more noticeable with 100% screen brightness.
Update: I sent the tab to service repair, and they sent me a new one. Guess what? Same problem again, right where it was on the old tablet!!
Definetely they are not stuck or dead pixel (I can say that because of the color of the pixel)
I was thinking, since I use a Tucano Youngster Case (http://www.tucano.com/shop/youngster-for-10-tablet-pc-1.html) which has a magnetic clip on the back, could this be the issue?? I'm going to try to take a photo at this pixel and attach it here.

Unfortunately pics won't show my pixels, they're just too small. However I tried passing another magnet (more powerful than the one on the case) both on the screen, with a direct contact, and on the back, where the case's magnet is located, but no other pixels got damaged. So I don't think the magnet is responsible... Does the iPad folder case has a magnet in direct contact with the screen too? If that's the case I believe that magnets don't affect screens at all (imagine iPad's owners complaints?).
What do you think?

Well, when I set my background as black, on this one and two other Android tablet I had, it sometimes show a short brown/gold line on the top left of the screen. Most of the time its not there thoough. So it just seems to be a software thing. Although I do not have any problem where pixels appears randomly throughout.

Can you get a pic, so I can try to say if we're talking about the same issue? However, my pixels are always there, even in the "Acer" and "Android" boot screen... so I doubt it's a software issue.
Just a heads up... Yesterday I got my 3rd Iconia, and guess what, same problem again. I think I will just live with it... but I'm extremely annoyed.
Does anyone knows what kind of problem can this be, with gold-coloured pixel only with black background?
You should load up the Screen Test app that sets all pixels to red, blue, green, black, white, etc. in sequence as well as displaying several resolution and gradient screens and see how those pixels react.
I bought one A500 that had bad Wi-Fi but all pixels were perfect. Exchanged it last weekend for a second one with working Wi-Fi and all the pixels are also perfect. I don't see any gold pixels.
I'll disagree with your statement "Definetely they are not stuck" in your second post because if they are always gold in all screens they are indeed stuck. Not stuck on white or black but still stuck on that one color.
Does this happen on all home screens or just one? I hope you can post a picture of some sort because I don't know where to look to see if mine has the same issue but, running Screen Test, I don't see any incorrect pixels in Screen Test.

Among three tabs they were in different numbers and position... however they were between 3 and 6, and in the middle (vertically speaking); horizontally, instead, i found them twice on the right half on the screen (volume keys up) but this last iconia I have right now they are on the left. I also managed to get some photo, I'll post them later.
EDIT: Unfortunately I forgot my camera's MMC at home... will get back there in 10 hours and post the photos. However I ran Pixel Fixer during the night (an app which alternates red/blue/green/white screens very fast) but the pixels were still there this morning.

I ran through all the colors in Screen Test and found only ONE bad pixel across the entire screen and it's only when the pixel is supposed to be blue; it's black instead. That same pixel is correct on all the other colors though.
Otherwise, at full brightness and on any color, they are all on correctly and off when the screen is set to black. I don't see any other colors as you describe.
If your screen is doing something similar across three different tablets, maybe it's something you are doing but I'm not sure what it could be.

I have one single white/bright pixel on the left side of my screen as well. I just got my nexus 10 today, so that is kind of frustrating. I was wondering with the PLS display a white pixel means a dead pixel or a hot/stuck pixel. I am hoping it is the later one, since in most IPS displays a dead pixel is black, but I am not sure if the same rule applies to the PLS display.
Does anyone knows if there is a fix for it or if it's dead for good?

I just got my warranty replacement yesterday. Noticed last night in a dark room that there is a small stuck blue pixel in the virtual soft button area, really an eye-sore. My first device had a hole in the backlight that looks like a big spec of dirt, so not as bad as that, but still irritating. I always seem to have the worst luck with ordering electronics (went through 5 sensations going around the warranty system )
Does anybody know of a way that it might be possible to fix this pixel? It's only visible when there is any blue or white on the screen above it. So if I download that pixel fix app and set the background color to blue, that stuck pixel screams, but if I set it to black or gray, it's not visible at all. It's only on if something above it is on. Almost like it's a short in the signal or something. Anybody know of a way to fix it? I've tried the pixel-fix it apps to no avail, albeit I haven't tried for more than 5 minutes.

Pixel fixer apps don't really work, some may report success only because it is an intermittent pixel fault that will just come back or would have fixed itself anyway. If it was as easy as flicking through a serious of colours the manufacturers of LCD panels would do this already as it costs them loads of money in throwing away panels with faulty pixels.
Some pixels will fix with gentle pressure, but often will just come back.
I'm sorry to say the only option is an exchange.

I'm getting a red pixel that shows up randomly. Either by the notification bar or navigation bar. It goes away if I touch the screen. Is this something that could get worse?

You have a faulty pixel that corrects itself sometimes when given a little bit of flexing as would happen when you touch the screen. It is unlikely to spread to other pixels, but one day the pixel may become stuck red permanently or may just fix itself for good.
It isn't uncommon to have pixels like that, although with improvements in manufacturing it's getting rarer. If you think it will annoy you, you have little option but get it exchanged.

Didn't realise you were a mod
Its a strangely behaving pixel too. It only shows if there are a lot of blue sub pixels activated on the screen. Example, if the entire screen is blue, the stuck pixel will scream, but if its red, green, or black on then rest of the screen (dark video or picture or something) the pixel is black. Unlike any stuck pixel I've had before. Only stuck blue if the rest of the screen has blue... And if the pixel is supposed to be showing black. If it's showing white or gray, it'll function properly, but if it's supposed to be black, it'll be blue.

The pixel is visible (bright, white maybe?) so it's not dead, just stuck.
And no, stuck pixels are not fixed under warranty unless they cross over a certain threshold (a certain number of them over the whole screen, or another, smaller number if they're all close to one another).
But it's not the phone's fault, almost all screens develop these over time. My old screen had 2 of them in under a year.
