Dead/Bright pixels problem?

Hi guys.
I'm interested to know whether Hero sets from overseas are experiencing this problem. apparently, users who bought it in Singapore (where i live) have this problem, and it's pretty widespread.
just curious to see if the problem is limited to Singapore or it affects other territories as well

Hi. I have T-mobile G2 in UK and I also have dead Pixels. As Fact I know people have this problem and It's not rare. I didn't send it back cos I Can live with it but i know people who sent it few times and still have received with dead pixels. Sad but its true.

i got 1 tiny little bright one.
annoying at first but i forgot about it after a couple of days. theres more important things in life to worry about. besides, most bright pixels right themselves after a few days/months...

i'd live with one or two dead pixels myself, but people have reported up to 8 dead/bright pixels, so it's kinda worrying

I do have around 8-10 dead? pixels but you can't notice them. One of them is bright enough to notice on black backgrounds and menus, but you hardly notice the other ones.
It's kind of weird though, they all appeared after 1-2 days of usage.

I have 1 bright pixel after 2 weeks using. The shop don't change the device with one dead pixel. Sad. In Hungary/Europe.

2 bright spots here. they are really tiny tho and i only ever notice it while booting which is not that often. no dead/stuck pixels on my hero *yay*

stuck = bright
sounds like someone needs to create an app for Android, like the apps to fix bright pixels on normal computer monitors, where u select the region on the monitor where the bright pixel is and the app constanly flashes different colors...sometimes rectifies bright pixels after a couple of hours.

i believe some of the bright pixels might well be enclosed dust ...

i have to say that i don't have ONE dead pixel on my screen. It's really great. My past device (xda orbit 2) also had another problem: dust gathering beneath the display. i don't have any issues with the build quality with my htc hero and i'm really picky too.
it's an unbranded german white HTC Hero.

If it was dust though, wouldn't we notice an increasing number of bright pixels as the days pass?

i haven't looked into this myself ... just quoting other people here.
the people in the other thread seem to have come to the conclusion it is dust enclosed in the assembly process. the seal around the displey seems to be quite good ... so no new specks of dust over time

Me too, I have 8 - 10 dead pixels but it hardly to notice them! you will notice them when boot the device.

i am not sure if mine is considered dead pixels but when the device boots up, the upper right side seems to be brighter than the rest of the screen (light shining out more from there)
however, once the device is booted up, it is no longer noticeable, maybe becoz the screen is not totally black. the only way thus far i can replicate this is to shutdown and boot it up.
does anyone have this issue?

Yeah, I also got the brighter screen in the upper part of it during boot, I think it is because of the backlight to the device so I don't think it's you really need to worry about.
But concerning the topic, I also experience dead/bright pixels during the boot up, around 3-4. I didn't even notice them during boot before I saw this thread and decided to take a closer look, not that a huge problem for me as i can only see them during the boot, and neither got I the patience to wait for it when it is at service.

first day with my hero from orange france and 1 dead black pixell !! RRRRRR

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.

Dave

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.
Regards,
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!

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.

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.

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.

Dead Pixels

Hi all,
Was messing about playing Ravensword yesterday, noticed during the loading screen that I have two, yes two dead pixels!
Shock horror, get me a replacement naow!
Lol.
But in all seriousness, has anyone else got any? If you do; what type of screen have you got?
I'm looking into mine now and will report back later.

Yeah I have heard others saying its a common HTC thing. The handset I have now has the issue where a tiny amount of light can come through the bottom right corner of the glass, but considering the flawless display I'm holding on to it for dear life
I work at CPW and checked through 5 units at my home store to find one without stuck pixels. They all had them. Wasn't until I went to another store I got a perfect one. Makes me think batch issues or sheer dumb luck!

I got 1st replacement from p4u and it's got one stuck white pixel which is visible when brightness between 10 to 60% approx but gone when full or lowest brightness I tried lots of apps but it's still there

Sent from my HTC One using xda app-developers app

I've seen numerous units with gaps and light shining through them. That is far more annoying then 1-2 dead pixels that are barely visible. But 14 ... c'mon - that is not quality control. Funny thing is: I had 5 out of the box. The other 9 became visible only after one hour of usage.

I have none that I can see, I'm not going to go looking for them as with a screen of this PPI you'll probably find some if you look close enough. At normal viewing range with Auto brightness however, I cannot see anything. what I am getting is a weird screen flicker every now and then when typing on the keyboard, I seem to notice it on greys but it could be my imagination so I'll just see. The phone gets bloody hot but testing a few devices at work apparently 42c is a normal battery temp when running some intensive games, so I guess I'll just live with the device slow cooking my hand.

That flickering is "normal" I'm afraid. Also appears on fixed brightness with mine.

I have at least 5, although 1 is clearly visible now that i know it is there. Another one is on the bottom corner so not visible unless you look for it.
The others i haven't seen in a non all-black screen. Not really visible
I'm on HT339W with PANEL_ID_M7_JDI_SAMSUNG_C2_2
Pixel fixing apps did not work

Had 2 Xperia z handsets with dead or stuck pixels so switched to HTC one, had 2 of them and both had clusters of dead pixels. Awaiting 3rd htc handset now.
QA definetly seems to have dropped on this years handsets. Had 3 of the flagships from last year (returned for various faults) and all were pixel defect free first time.
Going to stick with replacement HTC ones (for now) as it is a nicer phone than the Xperia. Would really like to just get a non defective handset and use it now tho, been 3 weeks of exchanges already as I have to do it all by post.

Thins is are you looking closely with brightness fully up and using white and black pages? You're going to have dead pixels when PPI is this high, luckily under normal use you wont see them unless there is a cluster.

Something people tend to forget is that with higher resolution screens come more chance for dead pixels. This phone has over 2.07 Million pixels (2,073,600). Dead/Stuck pixels are harder to detect with a ppi as high as this.
.00009645% of your pixels are dead.

Had my HTC one for 1 day. Purchased from affordable mobiles and have seven dead pixels, faulty camera, gaps too and bottom. Give me my amoled s2 back !!!! Problem for me know is I have micro SIM and my s2 is locked to 3 UK !!!!
Knew I should of waited for the s4 and this is my punishment.

I think these things come from first batches given the race with S4.
I will wait quality control calm down a bit their eyes.

Dumb question. I've had a couple of Samsung devices in a row and didn't have any dead/stuck pixels - other odd blotches, but no pixel issues.
Is this not possible on amoled screens, or was I just lucky?

Believe me or not but I got some kind of curse, since 15 years I buy tons of electronics and electrical stuff but only 5% of which turned out to perfectly fine and without any problem, almost every item I buy in the past have some kind of problem on arrival or it must be claimed for warranty

I'm getting panicky now, I'm on my 8th Xperia Z now because they all had, including this one, dead/stuck pixels!
I'm getting it exchanged for a HTC One, just hope that I won't be harassed by dead pixels! I'm only 21 and these pixels are making me age by decades, completely stressed out constantly exchanging phones due to pixel problems and having patronising blind turds in Carphone telling me they can't see anything!
