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!

Problem with my SuperAmoled Plus Screen!

When i received the phone today (around 3pm uk time) after an hour playing around with it i noticed 3 dark thick lines on the bottom half of the screen (on a gray background) i thought nothing of it at first and continued to use the phone.
Only just now i thought there must be a problem so i displayed a full white image and you could really notice those 3 thick dark lines. I then changed the screen brightness to max, min then back to auto and it was gone... BUT! when the screen dims a bit just before turning off i can see those 3 thick lines again just for those few seconds before the screen turns off.. it doesnt really effect me but it annoys me that they are there.. plus there might be problems with it in the future. I'm gonna go to my local Carphone Warehouse tomorrow and see if they can replace it.
I just want to know if any one else has had this screen problem.
Thanks.

Do the lines correspond to anything that is on the screen often like the keyboard or some sort of widget you have on your home screen?
These SAMOLED screens suffer from image retention and possibly burn-in. I've noticed it on my original galaxy as well as the Nexus S. As long as the lines go away after a few seconds it should be nothing to worry about. If you notice them there always then that could be a problem... usually the easiest way to see them is on a flat gray background.

oh boy, its too soon to be having any burn in. might be another issue.
my nexus one has burn in of the status bar at the top. and i can see a burn in of my entire keyboard on a white image. after more than a year of using the phone, oh well. but the status bar burn in was there within the first month.

the lines are:
1: just above where the 4 icons are at the bottom of the screen
2: where the page numbers are (dots)
3: just below the other 4 icons (widgets)
Thing is that these lines are solid and have no breaks in them.. so i dont think its the 3 points i gave above this.

I know it's too early for burn-in but some screens (might I say... all?) come from the factory with some sort of flaw. None of them are perfect and most have flaws so imperceptible that most people wouldn't notice. Every nexus S and Galaxy I've seen had some sort of area or line or multiple lines on the screen which were a bit different color, not as bright, or something along those lines. Some are worse than others, and I noticed the flaws right after taking it out of the box brand new. (I've been through about 6 Nexus S's between me and a few friends).
It's not really the same as a traditional LCD/LED screen since there's not a big backlight. Each pixel is individually lit and some may have specifications that are just on the edge of within manufacturer limits. There's almost 400,000 pixels on the screen... the chances of all of them being created identically is slim to none.
If it bothers you I say just take it back and get an exchange, showing them the problem area on the screen. Just hope your new one will be "less flawed" =)

Yeah, The last phone i had, had problems with the camera.. i went through about 5 of them and i ended up with one that was the same as the first one i had.
Can you guys have a look at yours?
Just open up a pure white image and check.. if there are no lines wait till it dims the screen and check again... thanks.

Did you put a screen protector on it???

which screen protector did u get? so i know not to buy it =)
edit:
Also ill post the results tomorrow if any one is interested.

take a screen shot of the problem? might not show but worth a try, then post it.

if it is really faulty, you should contact the seller to replace it.
I am really sorry for you, I will personal be mad if my long waited SGS2 comes with a super amoled plus faulty screen

well i dont have a good quality camera. You might of seen it before i changed the brightness settings but now that i have its kind of faint and you can only see it when the screen dims..
Gonna go to carphone warehouse now be back later

well before i went i called up all the carphone warehouses near me and none of them have stock.
I was told i only have two options:
1: go to a carphone warehouse and exchange.
2: go to a carphone warehouse and get a refund then order it online again.
So i should get a new one by tomorrow.. or atlest on friday.

no poroblems like that with mine. Screen is freaking perfect. On a side note i liked doing this test because I love staring at the screen.
Drooooool

well.. i went to a carphone warehouse.. and they had two instock. I exchanged it.. screen is fine but.. now after i got home i can see a mark/ dig inbetween the screen and the bezel (where the gap is)
again it doesnt really effect me but god.. now that i know its there.. i notice it so much that.. i might exchange it again Y_Y
This happens to me every single time i buy a new phone >.<... trust my luck!

well well well.
Went to lakeside since the one near me closed at 7pm.
Changed the phone again and this one had the lines on the screen and a dig in the silver bezel. She gave me another phone and the screen was perfect and there are no digs on the silver bezel...
In 2 days iv had my hands on 4 different S2's lol..
Last phone i had i also had 4 of them cause of XXX problems.. thought i was gonna beat it today and have 5 XD

Geebuz wept! I'm getting mine in from the UK tomorrow. I hope for hell sake it doesn't have imperfections. The ship back to the UK would be a disaster and if that one has a dig in the bezel upon return I'd blow a valve!
FINGERS CROSSED MINE IS PERFECT

as far as i know. this is the grid pattern on the super amoled screens. however. because of the poor QA/QC of the screens, some of those grid patterns are more visible than other area of the screen.
the whole super amoled is about lines on a grid pattern. if you notice more deeply, you will see that you also have those " lines " some where else on the screen yet they are not visible as the one you noticed.
i had to go through 4 galaxy S1 to get a good one where the pattern isnt "visible " through the whole screen.
its a defective unit. mainly poor Qa/QC. if you can live with it, it wont do you any harms. or get bigger. if you cant, then change it.
or and make sure you dont have a dud phone with piss poor yellow white on high brightness or pink gray on low brightness. because thats also a defect in super amoled screens.

Galaxy S2 Weird Screenburn issue

Ive had this powerhouse of a phone for just under 16 Hours, Screen has only been used for around half an hour etc,
Ive just noticed some screenburn on the screen The four buttons - (Phone, Contacts, Messaging, Apps) are visible on the screen when I look at a grey-ish background (Such as the speedx initial bg). Ive been through 6 Galaxy S2s, Three of them had this issue - Is it me, or is this a bit weird? Phone screen on for only 30mins since it was factory shiny&new, and theres already light screenburn.
Is this a characteristic of SAMOLED Plus, or is this a faultly batch? (Im on my 5th replacement phone from Amazon due to various faults). It seems a bit weird, a phone thats cost near £475 inc has this kind of issue.
Thanks In Advance,
Aman.
(Picture attached, You have to look quite carefully to see the greyish outlines of the boxes)

It doesn't look screen burn as it looks coloured. it might be the app you are running has transparency.

afaik, OLED does suffer from screen burn like plasmas do - potentially, but not that quick!

Well, it can happen. After a month i started seeing the same thing when pulling down the notification bar. So it's not app related, cause i don't use other launcher, i can clearly see the shadow of the 4 icons for a few seconds when pulling down the notification bar. They disappear pretty quickly, i'm not that bothered about that.

Also notice even if you just got the phone the very first second the digital clock actually burns through the notification tray and slowly disappears, I think its a technology limitation on the SAMOLED+

hi i dont know if my post will help or not
put i have a samilliar proplem with my sgs2 screen
i have proplems with colors like grey and dark blue
i will attack photos for u to see if u have the same proplem with colors like me
and my phone is only 14 day old
i really dont know if the colors are normal or not
p.s: make ur display 60/100 to see the colors
on my sgs1 the screen was way better
the first two pics are of the grey color ( to see if u have the same like this pic open msg and write a messege there is an option to write sound messege click on it
it will show the same thing see if u have the same like me
and the third pic is of the home screen to compare see if there is something wrong with ur screen
also could some one please look at his device and my pictures so i can now if there is something wrong with my device
thanks alot in advance

Seems like a SAMOLED+ limitation as you say. I was just curious, it shouldnt bother me much whilst im using my phone normally.

If the screenburn gets really bad, I suppose i can always just use the 2yr Warranty I have on the phone to get the screen replaced. Waste of an invisibleshield though.
Considering the phone is less than a day old, the screen might go really weird in 2-3 months - Which is what im worried about.

I would have to agree that the S1 screen is was a better display even if did have a more jagged edges on the fonts.

I have a similar issue in the messaging app, but with the keyboard. If I 'enable'(/turn on/whatever) it then disable it, it's 'shadow' stays there for a couple of seconds. It is however not a permanent burn in, so I think it's just the screen's limitation and it doesn't really bother me as this screen is still by far the best I've ever used.

wouldn't that screw up video playback though? sounds more like a software bug

I turned the clock on the notification bar back to 24hr , as i read/saw the AM/PM can burn in as they are displayed a lot longer then the 24hr digits which move at least every hour.

I just discovered this issue last night. I had been noticing a few lines here and there on my regular usage and I thought it was just a defective screen. Through the use of Terminal's blue screen, I realized that it wasn't defective.
I have a car dock, and use PowerAMP in the car every day. As you can see above, those burn ins are the buttons in PowerAMP. I went to take a picture of my SGS2 with my N1, and while looking at the blue screen on my SGS2 through the display of the N1, I noticed the N1 had the issue too!
I'm trying to run JScreenFix now to see if it solves the problem, but I highly doubt it.
Will Samsung even honour the warranty for things like this?

I have an SGS1 of 1 year old and my SGS 2 bought in may. Side by side, I will never exchange my SGS2 for another SGS1. Screen quality (colours and details) is by far better on SGS2. No comparision
I also don't see any burn in in both devices (keybord test, status bar...). Maybe some defective devices around that you just should exchange

If you want to test your screen or anything on your phone type *#0*# into the keypad
If the burn don't show up on green blue or red then its something else

I also have the same issue. I can see shadow of the System task bar. It was quite vivid on RED and it shows as lighter blue on blue colour. And on white it became pale white. Bright yellow as well on yellow.
I've tried various things like put the screen on full brightness on Black and Red and blue but still have the shadow there.
I will see if i can get my warranty repair.

I just wanted to confirm that the SGS2 sure can have a Burn In, as it was declared before as "Burn In Proof".
I noticed it while playing the recently released Game "Osmos HD". The game's color temperature is pretty blue-dark, and thats where I can see a slight burn in of the Task Bar.
Afterwards I checked my screen with various LCD Test programs and BAM - with low brightness I see slight burn in of the whole task bar. I can even see the signal indicator, the battery percentage and the spot where the clock sits.
But its only visible at very low brightness and a blue-purple coloring.
I called my brother, who has the Galaxy S2 as well, and he directly went and checked with LCD Tester as well. He, too, reported to me that he also has a slight screen burn in of the task bar, tho its very tough to spot. I guess, if you dont know its there, u wont notice it.
We both have our SGS2 models now for roughly a year, and the screens already seem to decrease in quality and stability.
I am a fan of Super AMOLED+ color quality and contrasts, but my 2 bothers and me have all the yellow tint issue, tho its not very drastic, and all devices start to get kind of a permanent screen burn in.
Its really sad to see that the otherwise fabulous screens already show its age. I hoped that Samsung learned from the SGS1's issues and user feedback, but sadly, it seems like they kind of ignored the fact that the Super AMOLED cant take much action...
My girlfriends Desire HD's screen (which was my phone before I got the SGS2) is still showing good colors. Sometimes I think about getting an LCD device again...

I think what most posters in this thread are reporting is Samoled ghosting, ie image retention for a few secs. Its not permanent, unlike burn-in, which some people may experience after some months of usage.

No, its not ghosting at all.
The taskbar image thats burned in is from MIUI. And since I am running either and Sammy ICS Build or Androidmeda for a while now, this image must've been there for longer than I thought.
As I said, I just noticed it yesterday while trying out the Osmos HD Demo. And its clearly the MIUI taskbar. Must be there for more than a couple of days already.

No screen burn on my Galaxy S2! Btw, been comparing screen to iphone 4/4s and Galaxy S2 screen way better! You have to have some sort of "telescopic" vision to notice resolution advantige on 4s... Who anyway reads webpages fully zoomed out? LoL... With magnifyng glass?? Contrast and colors advantige is huge on galaxy side....

For how long are you using ur Galaxy S2 now? Mine is running non-stop since a roughly a year now.
And yes, it seems like a permanent screen burn in on my end. Just checked again, same visibility of the probably weeks-old MIUI taskbar.

Will screen burn in be an issue like on the G5?

Being a big LG fan and owning numerous LG phones over the years, I think I join the community when I say the G5 was a flop. I enjoyed the phone over the last year, but it had many quirks that should not exist for a flagship phone. One of those quirks being screen burn in. I feel it started about the 7 month mark and is only getting worse. What worries me is that the new G6, which I very much looked forward to, has the SAME screen!!!! Isn't burn in just going to be an issue on that phone as well or is there more to burn in that maybe I am aware of such as phone temp, heat dissipation and so on?

LCD shouldn't burn in.
Are you sure you don't have a fault with the display on the G5?

I have read about it in multiple forums. Its possible its a fault in the display, but its not just mine.

It`s not burn in, it`s image retention

I have the same issue. Hoping it's not same for the G6.

I was have same problem on g3, g4 and now on g5. I change screen (g5) but same problem
Screen is "same" so i think problem will be on g6

I had a Nexus 5 for 2 years and never had image retention.
I deliberately avoid amoled, so the last half a dozen or more phones I've had are LCD (some of which the display will have been made by LG if not the phone) and never had image retention.
Even my Sony TV has an LG panel.

The last good LG phone was G2, others had burn in issue, I'm pretty sure that G6 will have it.
I know that the technical name isn't burn in but ir looks the same and happens to every LG G3,4,5,V10,20 soon or later.
PS: I was a big LG fan due G2 but got disappointed.

I had "always on" turned on, on my g6
can confirm the clock has burnt in

Anyone knows Nokia policy on dead pixels?

As the title says, i would like to know what is the policy of nokia about dead/stuck pixels on screen.
I got mine via a carrier some days ago, and yesterday i noticed 3 stuck pixels that wont go away, one of them is noticeable and the others 2 are noticeable seeing them very close to the screen.

Did you get answer. I also have one dead/stuck pixel on my screen, so i also like to know does warranty covers this.

By the way, does anyone know any brand with an acceptable quality control? I have tried almost everyone and each time I buy a new phone I am made to do a lot of RMAs until I find the right one. Dead pixel is the problem I find most commonly. Even a brand new S9+ I have just bough has got several dead pixels together.
