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.

[One (M7) Q&A, Help & Troubleshooting] slind:
I have now carefully examined 12 HTC ONE devices, and none of them had a perfect screen. Every ONE had at least 15 dead/stuck pixels, if you really count every one of them. This is so frustrating. Most of them are visible on black backgrounds, with brightness above 60% and indoors.

They came from different batches and carriers / selling points. What troubles me: if I really look at them for about 4-5 seconds, I can see the area around them flicker. Some of the pixels change the color in a repeating manner. And the quantity on this one is increasing. Was using it for 30 minutes: one dead pixel - after two hours it was four of them and now it's seven. All of them look green/flickering on black.

I can only assume that each and every device has them. But people don't seem to look carefully enough. I don't want to look for defects to feel unhappy, but this screen quality is nothing but a joke.

Dead and stuck pixels

I've just unboxed one and yes it has one black dot. It may be one layer deeper than the pixels but it is certainly an obvious black dot. There is also a bright (sub)pixel which changes depending on which angle I look on it (classical stuck pixel) and there is also a cluster of 2-3 elsewhere.

I'm on a contract now with three.co.uk and I am taking it back as soon as I can. The guy was very reassuring that if I have any problems with the screen then they will replace the phone. Weather this can go on until I find a good one remains to be seen...

Not a good unboxing experience, although I have somewhat anticipated this trouble.

[One (M7) Q&A, Help & Troubleshooting] 9a6or:
I was back at the shop first thing next day (today). The dead pixel (or at least black dot) was confirmed and I got another one which I sat down to check before leaving the shop. Unfortunately on 100% brightness and black background it had a stuck bright pixel (just pulled down the title bar). I was at that point passed on to the manager. He tried to blame it on software which an update may fix but I rejected that straight away as this is a hardware problem. He then brought out another box... which also had a stuck bright pixel. And then the fourth one also had one! Then he realised that we cannot go through all the boxes and that he should contact his manager and HTC on Monday. Fair enough, my standpoint was (is) that having now been through four units with bad pixels I've lost my confidence in the HTC One and I'd like to cancel my contract. He suggested that we should wait until he checks with his manager and HTC. He recognises that there is a problem, as he saw the bad pixels himself, but he needs to make a case for cancelling my contract. I gave him my contact details and someone will ring me on Monday (of course this is unlikely to happen so I'll have to chase them). I've checked the unit I came away with more carefully at home and in fact it has six stuck pixels. I am now waiting for how this pans out next week with the faulty HTC One resting in its box to keep it "as new" and "unused".

For those with some experience in this,

what are my chances to cancel the contract?

I haven't even opened the SIM card because the phone does not meet my expectations. Only verbally though but to my first question the shop assistant said that they would replace the phone if there was a problem with the screen but this route doesn't seem to work as all their units were faulty. I think they will try to give me another handset (Xperia Z, iPhone 5) or perhaps sign me up for the Galaxy S4 due out next week. The problem is that I don't need those phones: the Xperia Z is slower and I can get it for less now at Tesco Direct SIM free with 28 days return policy, iPhone 5 is simply no, and the Galaxy S4 has an AMOLED screen with burn-in problems likely.

I'm sure in the HTC factory they have a pile of perfect screens, a pile with a few stuck pixels most people will not notice and a pile that goes to the bin. If they can send me a 100% handset with zero problems then I am happy to go ahead otherwise I want to cancel the contract.
[One (M7) Q&A, Help & Troubleshooting] kinetic758:
Yikes! I was contemplating heading over to the Sprint store to exchange my One due to a green stuck pixel (there's about 3 more stuck pixels that are less offensive). After reading this post, I'm wondering if I should just stick with this one.
[One (M7) Q&A, Help & Troubleshooting] BenPope:
It used to be the case that for TVs and monitors the manufacturers quoted a defect rate for which they don't allow return. Something like 1 dead/stuck pixel in the middle and 3 on the edges. I'm not sure what has changed since then, it's obviously harder to manufacture smaller pixels, as well as an increased pixel count and smaller pixels. That's not very satisfying, but it seems that people are getting replacements with just one stuck pixel now.

I guess over time these things tend to improve because most companies employ quality control procedures.
[One (M7) Q&A, Help & Troubleshooting] mr_sock:
Yes of course. You can check on the spot to make sure it doesn't have the same issue.
[One (M7) Q&A, Help & Troubleshooting] gsw2:
That is really interesting, thank you. It would be interesting to see HTC's policy. My One just arrived this morning, a day before the actual release date here in Aus :) I'll report back with if it has stuck pixels or not, fingers crossed, I don't think I could live with even 1 stuck pixel, wherever it is.

An fyi, my S/N is HT34Axxxxxxx.

EDIT: Just an update, I have no stuck pixels, at the moment at least.

Just came back from Sprint to swap out my HTC One. Thankfully, the new handset has zero stuck or dead pixels.

Unfortunately, I did notice a blue stuck pixel that only seems to show up in the camera app and in photos taken in low light. I'm assuming this is a problem with the camera sensor. Probably won't do another swap since the pixel is located to the very right and I don't want to risk getting another unit with bad pixels.

[One (M7) Q&A, Help & Troubleshooting] Koga:
Yep -- I've got a dead pixel (black speck -- not dust) in the upper left. Sprint is sending out a replacement. Honestly I am not looking forward to it. From what I've read -- odds are the replacement will be worse and then I'll have to explain to Sprint that I'm keeping the original and returning the replacement. Sounds like a recipe for disaster. Oh well!

More to the point -- and like others have stated here -- it's weird because it's not just a single pixel.. It looks like a pixel, but it's too big to be a pixel. I don't have a microscope to determine how many are affected, or if there's actually physical damage to the LCD panel affecting a cluster of pixels.
[One (M7) Q&A, Help & Troubleshooting] livetag:
I have exactly the same issue - it cannot be a single pixel, it is too visible if you know what I mean. It may be 4 together in a square? I am unsure if I should return it but I also have a gap issue and the top edge of the screen is slightly raised hehe.

[One (M7) Q&A, Help & Troubleshooting] Ken4G:
I found a 3 stuck pixels on mine last night when I went to take some camera shots in the dark. The only time I see these white pixels is on a black screen with high brightness in the dark. I bothers me to know they are there and the phone isn't "perfect", but I'm not sure its enough to take back to ATT. Still contemplating.

For those that did take back to ATT, what did you do, just go to a store and swap it right there? They'll unwrap one and power it up for you to examine?

My wife's One also has one pixel, but it seems way brighter than my 3. With mine, you almost have to angle the phone a certain way to see them. You would never notice them in normal use.
[One (M7) Q&A, Help & Troubleshooting] lilfurbal:
Seems my HTC one has one stuck red pixel. It's noticeable at 60% and below brightness. For some reason it completely goes away at 100% brightness, can't see it anywhere, but it comes right back at 60%. Was unable to find information regarding stuck pixels going away at max brightness, this seems goofy to me.

I have no interest in exchanging it out for another or returning. This pixel didn't exist til a week after I got it anyway, so I could exchange for another that appears perfect at first then may get even more stuck pixels. Gamble, and a waste of time, and money paying to ship it back where I got it from. In the end, what works for me, is the realization that we do not live in a perfect world. Expecting any electronic device to resemble perfection is simply asking too much. I have yet to experience complete perfection, whether it through a $1200 ultrabook, $2,000 tv or a $200 phone. It will be replaced in a couple years :)

Also in my case if I want to watch a video without it being there I just bump the brightness to 100%... weird.

[One (M7) Q&A, Help & Troubleshooting] millicent:
Not sure if it is widely known, shouldn't hurt mentioning it again: for stuck or bright pixels try those pixel fixers. They really work. Had two pixels only visible on black background on more than 50 % brightness in a dark room. Even then they were only visible when looking from a side. 30 mins or so of those colored flashes seems to have fixed them both.

Recently posted about my replacement arriving with dust under the screen. I asked for a replacement because my original had what I thought was a dead pixel. Well, took the original outside today and looked at it in the sun. Turns out the problem with the original is not a dead pixel. It's DUST too! Smaller than the dust in the replacement, but dust nevertheless. Seriously, why don't they assemble these displays in proper clean rooms. This is nuts.

After reading all these posts, it looks like the majority of the units are defective, and the people who claim theirs are perfect, probably aren't looking hard enough because they don't want to find any.

Regardless, nothing in this life is perfect, so you might as well get used to any imperfections on your phone and claim that phone as your own!

Purchased my HTC One from the AT&T store on May 1st. May 3rd I noticed a dead pixel in middle left side of screen. The funny thing is it's only noticeable in low light conditions because auto bright turns the brightness down. If I manually increase the brightness to about 75% you can't see it anymore. I'm kinda anal so I might go in and see if they will replace it, but I might wait a few days to see if anymore go.

I have one dead pixel on mine no stuck. It's the first thing I check on my phones. It's so tiny you can hardly see it. Not even worth it to get it exchanged.

I've seen couple without any stuck/dead so saying all has them and the owners just don't know how to test for them is a bit ludicrous. I use the Dead Pixel Test app from the Play Store to check. Seeing as all units does suffer from this issue I guess I really don'y know how to test for them...

One important thing to add. Most people wouldn't post to say their device is perfect. Not because there are 50 people posting their defect means all suffer from this. There are probably 1000 more reading this saying "I'm glad I don't have this issue" and not bother to post it.

I'm always on XDA because I change phones every 3-6 months so from being on a ton of different device forums I can attest to this.

I currently own a HTC One and a Xperia ZL. From now going back to this time last year I've owned One x2, Xperia ZL, One X+, Optimus G, Note 2 x2, Galaxy S3, One X and Galaxy S2.

I have not had to return any of those because of defects, I either gave them away or sold them to get the next new phone (yes I have a serious problem).
