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.

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!

Week old nexus one, already dead pixels.

Well I received my nexus one about a week ago and I absolutely love everything about it...
Unfortunately I've just noticed two dead pixels on the screen. One top left and the other bottom right. Both about an inch in from the screens edge.
I've seen a lot of posts of people complaining about clicking edges and dust under their screens but I'm pretty sure this is not dust. The specks look identical to each other and are tiny in size. They are mainly visible on light/white backgrounds.
Unfortunately I live far away from any of the Google supported countries so doing any kind of exchange is going to be really difficult :-(
Anyone seen similar issues? Any suggestions?

There's a coupla apps on the market to check for dead pixels.
All they do is flash up white, black, red, green, blue so you can see what pixel is stuck. It might be worth trying one of those just to make sure they are actually dead pixels.
If they were working before, they might just be stuck pixels, and alot of toggling between colours may unstick them.

But if it was a stuck pixel then you would see it lighting up on dark backgrounds but these are only noticeable on white or bright backgrounds.
BTW I have already tried the market apparently and no joy.
Has no one else been noticing these?

I had one stuck pixel that appeared a couple days after i got my phone
but i fixed it and it came back like 5 times.
But knock on wood its been 4 weeks and it hasn't come back.
Mine was weird it would only show on the lock screen and it was very random but once i swiped to unlocked it went away so it wasn't that bad.
If i were you I would return it especially were its two pixels and software isnt fixing it.

When you say u fixed it what do you mean?
Just to clarify, the dots on my screen look dark like there's no light coming through them. That's dead not suck right?

OLED have very deep blacks so its hard to tell if its stuck on black or if it is dead
...anyhow if you cant fix it you should return it.

Man returning it is a such a mission as it was bought in Singapore and I'm not even there any more...
I suppose I could find a way to send it back there and then from there back to the US.... heh. The problem is that I only received the handset about a week ago so if these kinds of problems have been reported since the launch whaat says the replacement wont have the exact same issue? Which would then be a massive waste of time and money ;(

Thats the problem i even set up an RMA to return mine but had a gut feeling i would regret it. So i canceled my RMA and prayed the pixel would eventually not stick anymore.
I didn't want to take a chance of getting a referb phone with other issues.

I feel your pain EVERY device that I get now days that has a LCD screen ALWAYS has at least one dead pixel. But to my surprise my Nexus One is 100% fine .

Stuck Pixel Desire HD

Hello, i'm sorry for create duplicate thread from http://forum.xda-developers.com/showthread.php?t=1093995 because i did't get any answer, so i decided to open new thread at this subforum, because many ppl look at it
few weeks ago [3 may 2011] i bought a new desire HD
and today, i realized there's a stuck pixel at the top right panel near the clock, the panel gray and the stuck pixel just colour almost same, take time and focus to realize it.
i create a new thread because all other threads of the stuck pixel didn't give me any solution
and this stuck pixel not just stuck in 1 colour
but,
when the screen is white, the pixel is red
when screen blue, its blue [dissapear]
when screen light purple, its light purple
when screen black, its black
when screen green, its blue
idk if the pixel really gone when its blue or purple, but my eyes are normal i guess..
JscreenFix tested, 1 hour, no work
tapping, scrubing, massage method, no work
is there any other method that you recommend?
i didn't root the phone yet because it still in Warranty, and i guess if i bring it to HTC Care, i won't get a new unit, but a new lcd, and the mechanic sure open the phone and broke the void sticker..
any suggestion?

If you have tried all the above I would phone HTC and try and get it replaced...
Good luck as some people have problems replacing phones with dead/stuck pixels as they are allowed a certain percentage of dead/stuck before its deemed a fault

The HTC didn't want to replace it, but i contact the shop where i buy and ask them for replacement, but still is there any other method that someone had test it and work?

I'm not suggesting this, do it at your own risk, don't blame me if you brake anything!!!
There is a way of "unstucking" the pixel by pressing hard on your screen(so I've heard, never had a dead pixel in my life=>never tried it). It looks like that your pixel isn't actually "dead"(it would only shine in one color(white) or wouldn't shine(black) if it was), but rather "stuck"(again, so I've heard, and didn't do any research about it, how and why is this happening, so there's a big chance I'm wrong).
If they won't replace your phone, and you don't really want to try exotic stuff that might break your phone(like pressing hard on the screen/dissassembling the phone and poking the screen from behind with the screwdriver/yelling loud at it), there isn't really anything that you can do about it, except get used to it...

I've had a stuck pixel on my Desire HD since 4 days after i purchased it, which was at the beginning of December. At the time, i tried everything i could to fix it but nothing worked. So now i just learned to live with it.
Btw, i really recommend to not try push/massage on the screen because the glass on the DHD does not flex. If you apply enough pressure you could shatter the glass (considering it's not gorilla glass).
So if JScreenFix doesnt do anything then im afraid nothing can really be done, unless you decide to disassemble the phone yourself (i dont recommend), or brake your phone purposely so HTC will replace it

It takes 3 dead pixels to replace it with a new one, here were I live. I have one on my DHD, but it's in the down right corner, can't even see it, noticed it by accident when i was watching a video that was cropped so it had alot of black around it.
Otherwise, don't see it-don't care
I've even had a dead pixel on my Philips monitor, for 1 year, and then it just dissapeared. And it was a red ugly one, right in the middle of the screen, very annoying.

I've had a stuck pixel for some time now. It's bright red and in the middle of the screen, i just lived it. I barely notice it. Only when i look for it do i find it. I'm tempted to say 2.3 fixed the problem for me but it could just be that i changed my wallpaper from the live sense one to a black one.

[Q] Display fault. Hardware/software?

So i recieved my Galaxy s2 the other day, as a replacement for my HTC HD2 which was in for a repair with a broken screen - apparently it was 'unecconomical' to repair - but i certainly wasnt complaining!
Awesome phone, had it for two days, rooted it fine using Odin and superoneclick - fantastic tool..
After rooting i re-flashed with stock kernel again.
All was absolutely fine, i was using my phone without problems until a few hours later (yesterday evening) when after putting it down for five minutes and picking it up again, there was a pixel wide horizontal line running across the screen.
They are not dead or stuck pixels, as they change colour with the background- they just appear extremely brightly, so stand out from the rest of the display.
No amount of adjusting has resolved this, rebooting/hard reset etc. the line remains prominently running from the right side, and slowly fading to the left.
Ive searched online but cant see any issues with screens like this, just dead pixel lines and stuck pixels.
If anyone may have an idea on whether this could be software related problem or hardware related would be great to know your thoughts.
Cheers, Alex

I would be taking it straight back . I got a couple of sgs2 handsets back in may when they were 1st released and i had numerous screen issues. i got one a few days ago an my friend got one yesterday and the screens are pretty much bang on (tiny tiny yellow tint if you go looking for it)
No lines , no dead pixels , beautifull screens even with the slight yellow tint
I hated my 1st screens so there are defo some bad ones knocking about and some that are literally 10x nicer to look at
Like i say take it back buddy
Good luck with it and let us know how you got on
Also pictures of the problem could be interesting

Yep I definitely will...
Just whether to un-root and reset flash count first or not - probs a good idea im thinking.
Aside from that i agree its a lovely display- ive heard about the yellow tint but noticed it on mine.
Will try and get a pic up before it goes back..
Cheers for the input!

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.
