How often is the "dead pixels" problem?

Hi guys!
I'd like ask all of you how often is this problem in Hero series?
I bought one a month ago and it has some stucked pixels, but I heard that the chance of getting even worse phone is bigger, so I decided to keep this one, because these dots are practically invisible during the common work with the phone.
I can see one or two if I set the brightness level to full, but thats my second question- how many of you use brightness on full or you do prefere to keep it on automatic? I discovered that on manual setting the phone loses light sensor function, am I right?

A couple of dead pixels here too... But can only really see them when I boot, so it's ok. So far...
p.s. I use half of the brightness. Full brightness i s great to show off but sucks up too much battery!!!

A few can been on boot on my phone too. Not really a big deal though.

From all opinions I got (plus from the other forums)- here is the statistics:
38 people don't have any/ 34 do have this issue...
Not good for HTC...

Hardly an exhaustive sample! Plus, you're more likely to get "positives" based on the thread title, because it's far more likely that people with dead pixels will read it!
That being said, it is *very* common, and not just on the Hero. You don't need to google for long to find that the iPhone has similar issues.

Yes, you are right, but still.. even those people with this problem are enough evidence that it's something wrong with the quality control. I am not saying that it's happened only to HTC Hero, but it's a big problem in general and I don't agree to give 400+ boxes for getting stucked/dead/bright and so on pixels. This is just kind of thinking, and when the manufactures realize that it would be much painless for us- the clients. It's all about the quality control- in general- monitors, TV's, cameras, laptops...esspecially when the items go above define price. You get it what I mean..there is no room for joking with the clients. Ok, I am gonna change the device- once, twice, three times, but where goes the starting point that has made me convince to buy exactly this model? Nowhere..the same with Iphone, Sony Ericsson, Nokia... We are living in 21st century and the perfection is tide connected with this time..or at least that's my point of view...

The issue is that the yield of 100% "perfect" LCD displays is actually quite low. As this article states (under Quality Control) it is economically prohibitive to throw away otherwise perfectly good LCD panels for the sake of a few dead pixels.
Unfortunately, as it currently stands with LCD manufacturing methods, for us all to be *guaranteed* screens free of any dead pixels, we'd probably have to pay an awful lot more for our devices since many screens would end up having to be thrown away.

Dave

Ive got none however I do have a little light leak in the top right of the display

I have 2. But I dont think they're dead pixels but dust that's visible on the black background with booting. Cannot see them at all with normal use.
If they were completely dead pixels it might have been more nasty.
It's in the nature of fabricating lcd displays. And has been a problem for a long time. Anyway, with my Hero I can't be bothered about it.

If you have stuck pixels, try JScreenFix. Its free from the Market. worked for me!

i had alot on my first device.. i traded it in.. this one has 2.. they only show up during booting.. so i guess its not a big deal

I've had a couple of Heros by now:
1. very visible dead pixel (centered in market search field) -> returned
2. Really large gap on top side of display glass -> returned
3. happy until after 3 months suddenly loads of dust appeared below display glass -> returned
4. dead pixel in prominent place -> returned
5. I'm very happy again. hope that dust will stay away from underneath the display glass.
So, my personal record so far: 4/5 Heros are flawed (3/5 Heros on arrival).
That's really sad as it is such a great phone otherwise.

I've posted about this before, if they appear as bright white specks when brightness is up full (such as during the boot animation) then it's dust, not dead or stuck pixels. You can open the phone up and remove them. I've seen it on multiple handsets, turned out to be dust every time.

In my case the first pixel was permanently green, while it was a red pixel in the second case, definately not dust. (I think these are correctly called hot pixels, not dead ones.)

i hab a dead pixel on the first day after i bought it. But i went to the T-Mobile shop immediatly and they changed my hero with a new one without any problems! With my "second" Hero i dont have any Problems till now. Seems like there are 2 generations of displays!
*edit*
my dead pixel was near the upper left corner and it was totally white. actually you could only see it if the rest of the screen was red or black. but as it was a mistake i changed my hero anyway!

Screen littered with white stuck pixels. HTC policy? Warranty?

My screen is littered with white stuck pixels. Best visible with an all black image and 100% brightness. I don't know if they were there from the start. I guess I was too excited with the HD2 to even notice them at first.
Now I have at least 7 of these stuck pixels and 2 of them are only 2mm apart.
I can't find the policy regarding dead/stuck pixels anywhere. Not on the HTC site (I live in the Netherlands, Europe) nor here on the Leo forums or even trying google.
Does anyone know the dead/stuck pixel policy HTC has in Europe?
I bought the device on december 12th.
It would also be nice to use this thread to find out if more people are having this problem with the HD2.
Thanks!
EDIT: Added a poll. It might be nice to know how many of you are suffering from dead pixels to get an idea of the quality of the HD2 LCD screens used.

From what I've read in another thread, someone spoke to HTC when they had 1 dead pixel and HTC said they'd need 10 before it was a warranty issue. Personally, I think it should be an issue if there's any dead pixels, especially when the thing is only a month old!
Get in touch with them and see what they say themselves.

I'm waiting for an answer from HTC. They are not that fast..
I also read that thread, but to be honest I've never heard of so many pixels needed to be dead to be covered by warranty.
The title of that thread states only 1 dead pixel (which is normally not covered by warranty), so I thought it would be a good idea to open a new one and check out the experience of other xda users.

Found this for the Asia Warranty, and it states on page 4 of this document, http://docs.google.com/viewer?a=v&q...&gl=uk&sig=AHIEtbQJk8yP96b-ddibr9YKV3EYPCjKXg
14. Due to the complexity of liquid crystal displays on handheld devices, dead or bright pixels
may sometimes occur. If the following occurs within 14 days from the date of purchase, then
you can ask to replace the LCD at our authorized service centre.
(a) 3 or more dead/bright pixels (*) anywhere on the liquid crystal display.
(b) If there are only 2 dead/bright pixels, then they must be within 5mm of each other.
(c) However if the conditions listed below occur, then this warranty is null and void.
(*) ”Dead pixel” – a pixel on the liquid crystal display (LCD) that shows no light at even
when it is supposed to.
(*) “Bright pixel” – a pixel on the LCD that shows only 1 color (usually white) and no other
colors at all.
What (C) refers to I don't know.... the 2 conditions below are knackered pixels! Give them a ring - on laptops it was 6 or 7 accross the screen, or 3 or 4 towards the centre. I wouldn't tolerate that many on something like a phone, as you're looking at the entire screen all the time.
Good luck

Again a different answer. I hope HTC replies soon.. Someone on tweakers.net told me they look at a % of dead pixels. I think I will give HTC a ring tomorrow instead of waiting for an e-mail.

Wow. I had four of these, the last one I sold still sealed in its box but the other three were perfect with regard to not having dead pixels. How unlucky! If I were you I'd return it for one of the numerous other faults, never mind their dead pixel policy. Say the SMS fault is the issue, or the crackling call quality (if you have it) etc.

Those faults are something to try indeed if they reject the pixel claim.. However the sms issue can probably be fixed with a hotfix.. Can't say anything yet about crackling call audio, didn't use it to call yet. Still playing with it and awaiting my soft resin case + screenprotector
I just noticed another white pixel.. So that is a total of 8 already.. Seems like they are all suddenly appearing (not that I'm paranoid, but I didn't notice any white stuck pixels before and I would swear there were "only" 3 yesterday morning when I first noticed..)

Ok, I gave HTC Netherlands a ring and here is what they said:
There need to be at least 4 dead/hot/stuck pixels present, OR
There need to be 2 dead/hot/stuck pixels at a maximum distance of 5mm from each other
So I brought my HD2 to back to the store I bought it from and they have sent it in for repair/exchange. I don't know if they will replace the screen or the complete handset, but I pushed them quite a bit to replace the entire handset (it's only a month old and I don't like the idea of it being taken apart already :S) I'll keep you all informed.

Good to know.... hope yours comes back fine!

Thank you! I hope so too! Good thing is that they (the store) also filled "in perfect condition" in on the RMA form. Sent back a Nokia once and it came back all scratched up and I couldn't fall back on anything to prove it wasn't scratched when I sent it in.

Indeed

I have a UK Tmobile HD2 Ive only had it 2 weeks and had noticed a white pixel appear a couple of days ago and now I have spotted 2 more (bottom left, middle and top right of the screen) and I can also just about see 3 not very visible RED stuck pixels.
I will be taking the handset back in to the store tomorrow to see what they plan to do about it, they will probably send it off for repair but i will ask for an exchange although the store does not have any instock.

my HD2 suffers from a dead pixel too.
Luckily it's only 1 (and i hope it won't get any more).
I have my HD2 a week, and yesterday i first noticed the dead pixel with brightness on 100% and a white background.
Hope they do something about your situation, because that many dead/hot/stuck pixels isn't fun anymore, and the worst part is you can't hold your eyes of it once you noticed them.

Is there a software to fix stuck pixels??? I have spotted a red point which can be seen only in some applications with black background. But it isn't seen in a totally black picture.

Any update on this?
i live in NL and curious to hear if its fixed for free.

Black dead pixels?
Are dead pixels black or white? I have few in a small area after I bought it used a year ago. They haven't spread but does anyone else have this problem?

i am on it too .... a blue pixel only on black font.....

New Note - Dead pixels

Bought a Note yesterday from phones4u, had to go through 4 of them before I found one without any dead pixels on. Just summat for prospective buyers to look out for, check the screens before you leave the store. Well worth it though, awesome phone

Just FYI, in the UK, if an item developed fault within 21 days after purchase, the customer can demand either a full refund or exchange.
I'm not sure if full refund works on contract phone, but customer have the right to exchange a faulty phone for a new one from the store within 21 days.
P.S. Enjoy your Note, I had my since Nov and still loving it. This come from someone who change phones every 3 to 5 months.

Yup, well the one I got now is perfect, I reckon they must of had a dodgy batch as this was apparently the first one of a different consignment.

Try going into a dark room and put a full black background and see if you notice any dark splotches. There are some Android wallpaper like No background I believe. This is a common problem with SAMOLED HD devices from what I've read. Don't know if you can get a replacement for that.
EDIT: Oh yes, what Note did you get Ceramic White or Dark Blue?

No, that is somewhat of a feature of Amoled displays, however, it's a damn sight better a display than the one on the galaxy nexus. I had one of those before this and I'm reasonably impressed with this one.
Oh! I got the blue one

I also went through 3 with handtec....all with dead pixels...

5 days into ownership....dead pixels

What does a dead pixel look like? I get mine soon also and never owned a AMOLED screen before.

I have had a single dead pixel since it arrived 5 weeks ago (white 16GB). But I don't care much because the pixels of the Note are so small that I don't notice it 99% of the time even though it's on a rather central position. Only rarely when I watch movies that make the screen go very bright for a while I happen to see it without searching for it. But it never bothered me when browsing the net or reading mail although I can see it on a white background when I look out for it and know where it is. I have had a SGS I for ~20 months before which didn't have any dead pixels.

Hopefully my white Note doesn't develop any dead pixels like my GS2 had before after a few months.

New units with light bleed.

Anyone recently purchase a new unit that has no light bleed or does this problem still exist?
Sent from my Galaxy Nexus using xda app-developers app

I purchased a unit two days ago that turned out to have 1 dead pixel and an additional two dark "spots" which i assumed were a small group of dead pixels bunched together (maybe 2-3) and some lightbleed on the top of the unit. Additionally, it had somewhat of a "bump" along the side of one of the edges of the tablet, so if you placed it in landscape on the table you could make it rock back and forth (rather than standing still and sturdy as it should). That was a unit from the CCO batch, so I'm guessing December 2012.
I exchanged it for a new one yesterday and this one is FLAWLESS. I have NO light bleed, NO dead pixels or dark spots, NOTHING. This thing is absolutely perfect. No screen lift, NOTHING. I'm literally so happy with it. Worth noting is that this flawless one is from the CBO batch, so November 2012 I'm guessing. Absolutely flawless.
I guess I was unlucky with the first one since the CCO batches should be the best one's as they're the latest.
Both were the 32GB Wifi version (no 3G)

Cool! Thank you. I have a 32 gig that has some light bleed that I thought I could ignore but I can't. Selling it on craigslist. Then probably getting another one from Walmart for an easy exchange in case its defective.

I wouldn't hang myself up on light bleed; it depends a lot on how bad it is. Most of it is bareable imo, but as with all faults, you can never unsee them once you've seen them. If you aren't happy you have every right to get a tablet you are happy with I'd be much more hung up on dead/stuck pixels. Those things are literally in your face 24/7 once you see them once.
Good luck!

Dead pixels?! Nooooooo

Just to clarify, it's a stuck pixel not a dead pixel. My bad...

Well you should have checked if you are buying it second handed. Probably seller sold it because of that instead of asking for a change.

He said the phone was sold sealed, so the seller couldn't know there were dead pixels on the screen.

As I said in the initial post, the phone was sealed. Unless the seller was psychic it is impossible that he could have known.

Mine had a dead pixel but I got it replaced today.
Only noticed second day, its quite hard to spot it. But yes it's anoying.

Just to reiterate, I love this phone, which is why I'm more gutted than I would have been that some dead pixels have slipped though the production line as I really didn't want to have to send the phone off. I just wondered if anyone else has found any dead pixels a or if I'm just Mr Unlucky as I seem to have had a run of bad luck with HTC over the past few years.

Only problem is I only have a repair option as I didn't buy it myself and don't have a store receipt. If I did I'd just swap like you. If It were not for this annoyance I would be 100% in love with this phone!

I don't believe HTC are stating the phone to have a zero defect pixel display. The more pixels you push into such a small display the more chance of having defective pixels. Stuck pixels are worse than dead ones as they blink at you on a black background. Dead pixels you normally have to search for.
Believe me I would be just as upset as anyone if I found bad pixels on mine (fortunately not yet)....but I think its asking a bit much for perfection on every display out of the factory considering the pixel density and resolution.

That sucks man. Unfortunately for you that you only have those two options.
I would be so mad if that happened to me, but I generally buy from a store or online and get replacements easy.
Sorry man.

There is an app pixel fix or something like that. Try if it works and let me know

Had a few bad experiences with the One X last year but after seeing the One hardware I just had to give them another chance.
I must say, I'm absolutely in love with the hardware. It's beautiful. Only problem is that while playing Transformers on Play Movies I noticed that I have two dead pixels at the top half of the screen. I'm absolutely devastated as I thought this phone was perfect up to this point. I bought the phone second hand (albeit sealed) so don't have the option of an exchange. My options, therefore, are live with it or send it off to HTC and be phoneless for days or weeks.
I wouldn't have thought dead pixels would be noticeable on a screen with such a dense resolution, and they're not really noticeable on anything other than black - but they're REALLY noticeable there.
Have any of you guys got dead pixels? I'm a bit disappointed to be honest as I've had a tonne of iPhones and Samsung devices over the past few years and haven't seen a single dead pixel but with this and my One X from last year I've had two in a row with HTC.
Very disappointed.

Hi, can u take a picture to show us which area has dead pixel. Thanks

Dead pixel = Black
Stuck Pixel = Any other colour
You can't fix black (dead) pixels as they are broken. Stuck however sometimes can be unstuck and fixed, but again can get stuck once again. Its pointless asking for pictures as it would just be a tiny spec on the screen. Visible only if you zoom like 200%. Mine was on the top left quarter and was a dead pixel, so I got it exchanged the next day in store at phones4u.

I wouldn't bother, software never works 99.999% of the time, if ever.
The pixels are to small on the HTC One that if you can see them, then it'll be a small cluster and I doubt the dead pixel policy has changed so you probably can get a replacement.
I've seen a lot of these HTC Ones with dead/stuck pixels online, every picture I see of them has them and even the one at the shop has one too.

Hold on one second....since when can you get the HTC one? I didn't think it came out until next week at the earliest outside the USA

Not exactly. I had ONE dead black pixel and i could see it nice and clear on a white screen. Thats every time I was browsing I'd notice a dust like spec. Its not hard to see especially when you put it on specific colours. Again I had only one dead pixel not a cluster.

See the words I highlighted.... Doesn't seem to be a dead pixel to me. If that's really the case just ignore it. It will just fix itself in some time or just massage the part of the screen or use some pixel fixer on google play.

if you have one dead pixel, i say keep it. HTC has ALWAYS had problems with dead pixels. i went through 8 G2s (Desire Z) and only had one or two without dead pixels. one even had a display that looked like it suffered from burn in.

Why the hell would you keep it? Stupidest advice ever.
My first HTC One had ONE dead pixel. I exchanged it and got a brand new shiny one WITHOUT any dead pixels. So you're telling me I should've kept the faulty one and lived with it? lmfao..

HTC One is already available on hongkong? Cool...
If it is I could just cancel my pre-order with handtec, travel there and buy the HTC One. In the end I could save alot with customs & stuff.
