[Q] Why so many dead pixel phones out of box - Galaxy S III Q&A, (US Carriers)

I have not gotten my Galaxy s3 yet, but i am beginning to become a bit concerned with the number of reported dead pixel phones out there. I don't want to drop a giant chunk of change on a phone that may not have any dead pixels at first but quickly starts gaining them as soon as the phone drops out of warranty.
Does anyone know what has been causing these phones to ship with dead pixels already?

The simple answer is: Super Amoled Technology

Question to add to that. Planning on buying this phone. However want to make sure I don't have any dead pixels. Is there a program for it or do I just need to bring my magnifying glass to check the screen?

yes, if you dial *# 0 *#.
From there you can click on the color (choices are red, green, blue)
it will fill the screen with that color and from there you will see a dead pixel if there is one.
Just did this on my vibrant and it still has no dead pixels. phew

there is an app called screen test..

@ caffeinated chris I just love this!
"...yup. and now I owe over a hundred dollar fine for flashing a rom while driving"
I have not been caught....yet!

dead pixels on your vibrant?

Anyone else randomly get a line of dead pixels across there phone? Any idea what could have caused this? Or if it can be fixed?
I have had this phone for over a month now and don't really want to have to return to t mobile for a "like new" phone. This phone is in perfect condition, I have had it in a silicone case with screen protector since it was out of the box.. And has never been dropped once.
Any ideas for me?

Fortunately, no, I don't have that problem. But, I have seen cases where a scratch on a screen will show a 'rainbow' effect seeming just like dead pixels. Not on this phone, though. Knock on wood.
I have a little rainbow line in my Vibrant but I dont know if its for the screen protector and i dont want to remove it
Called cc and they are going to send me a like new.. Seems like its all I can do

sorry to bring this back from the dead, but I have a single dead pixel in my vibrant screen as well.
this sucks, bc i took all that time to root my phone and got it running with the rom and kernel of my liking and now i have a dead pixel in the screen that bothers the hell out of me.
i have tried running strobe light, and also pixel fixer from the market with no luck...
people with dead pixels should all post in here so we can compile a list.
I had the problem of the "rainbow line" that I thought were dead pixels. Turns out it was indeed the InvisibleShield screen protector as others have suggested. Removed it, put on Real Look, problem is gone. Screen is beautiful.
no i can confirm I def. have a single solid dead black pixel... i have tried everything, but no luck.
I am going to wait until next year, and let this phone get all mangled/used and then call CC before the 1yr stock manufacture warranty is up and get a brand new device...
sucks ill have to go through all the root steps again, but a 500+ dollar phone should not have dead pixels in less than 2 months of ownership. (SAMOLED is not perfected yet? shortage and new 5.5billion $amsung factory????)
i think we should sticky this, from what i can tell from searching and scouring google - many owners are having similar issues with dead and stuck pixels...
some are able to fix, but most are not.
it would be nice to see just how many vibrant users are having this issue, or SGS users across all carriers for that matter? (vibrant seems to have the best display, as ive had them all side-by-side).
Mods, Admins? can we get this going?
phones aren't any different than tv's or monitors....you get dead pixels on occasion over time
1 dead pixel isn't going to kill ya, live with it or get a refurb replacement

Dead Pixels...

So I work for Sprint, and I just got my replacement and come to find it has 2 dead pixels. I'm within my 30 days but what you guys think? keep replacing until I get one with clearly 0 dead pixels? anyone else get bothered by 1 dead pixel or what.... the first evo 3-d had 4 dead pixels.
yes, who the hell wants to have a screen with dead pixels? I certainly would not pay for that.. others have returned it.
I am going on my 4th evo but for hw related problems such as locking, not charging etc. if i got one that had a deal pixel.. it would go back to HTC/sprint.

yeah me either....id like to see these dea pixels if u can post a PIC.....also i thought someone said that theres an app that can detect if u have dea pixels.....anyone know what its called?
I would not keep a phone with a dead pixel and i didn't, went through a few of them. to me it's a defect, what's the reason to not return a brand new device if it has a defect. but on the other hand that might sound like i am spoiled, the phone still works the same even if there is one dead pixel.
Yeah, to me, a dead pixel is a defect. I would not pay $200 for a brand new phone and settle for it to be in less than perfect condition. You can download "Dead Pixel Test" from the market. It just displays solid colored screens, which make it easier for you to spot a dead pixel.

yeah its in the Market called "Dead Pixel Test" it goes through all the colors to see if you have stuck or dead pixel's. I haven't see any yet and have had 2 E3D's.
I have a stuck pixel, on green. It's really only noticeable when using the camera. I'm going to exchange it since I can, otherwise it's something I can live with.
ive never had a phone with a dead pixel..or maybe i've never noticed it..hmmmm

Probably the latter.
My recommendation is if you do not see it, don't go looking for it. Odds are you will probably find 1 or 2 but if you do not know it is there, then who really cares.
Also, the pixel is not dead unless it stays black. What everyone is seeing is a stuck pixel and it is very common on these screens.
My first 3D had a stuck pixel. This one all pixels are good but there is a big-ass speck of dust under screen. I hate to do this, but I'm gonna have to go back and either have it cleaned or replaced. On another note...my 3G is kicking ass today with the stock EVRC Home and Roaming settings in my living room! An average of 5 tests 1090kbps D/L 410kbps U/L here in Tacoma, WA...not bad! Hope this lasts!!
So today I got my 3rd replacement and it actually has more dead pixels then the 2nd replacement... The 2nd one I think im going to keep since its 1 pixel on the screen and 2 on the bottom near the buttons... I don't want to keep having to do return kits and fighting for credits... its harder for us that work at sprint because we don;t get the exchanges in-store everything is online...
boy do you have that right... if you don't see a dead pixel don't go looking for one!
many years ago I bought a hans g monitor from newegg that was on super sale... so cheap it sold out fast...
so everyone was reporting anywhere from one or more dead or stuck pixels. the people with the stuck pixels were for the most post able to fix them by gently massaging them. a few had the pixels stay stuck. others had dead pixels.
I personally have a few in a horizontal line. they are stuck in a dark grey which could have really been much worse.
but after so many years, the monitor with stuck pixels is still worth they price I paid. sure, we paid good money for our phones, and I do expect a product that is one hundred percent, but if the pixel is out if the way or isn't easily noticed, why not keep it?
then again, our vision is concentrated in a much smaller area so it might be really bad. but either way, while curious I won't be checking for damaged pixels! cause that might just drive me insane because you can't un-see what you have seen lol

3 dead pixels here I think, but you only see em if you staring at a lit screen with nothing on it... And if you doing that then you just tryna find a complaint

I am still up in the fence about returning my phone because of one tiny stuck pixel.
I think the question is, how many EVO's would I need to go through to get one without. I am guessing a lot more people have stuck pixels that just don't know about because they haven't found them yet.
I think the odds of getting a perfect screen are probably far less then getting one with stuck pixels.
As the 30 days grows closer this decison is becoming harder and harder and I keep talking myself out of the return thinking I might get something worse but I am just not happy with non-perfection!

Maybe you exchange the one you have now and if it has problems you should return it and wait for the next hardware version. Maybe it will have less problems.

So I bit the bullet and went for the exchange.
I am happy to say that the new device has no dead pixels! What is does have a the slightly crooked screen but I would have never even known what that was if not reading it on here so I can live with that over dead pixels.
Also, my screens colors seem so much better on this one. Maybe the misaligned screens are the ones with the whiter whites because it definitely looks better?
One thing I found weird was the lock screen was set on the weather one. My first one was not...It was definitely an un-opened box and I didn't even think about till hours after when I was like, um I didn't change my locks screen and it had the weather one as default.
Anyone, much happier with this one....

I will tell you but in all honesty if you haven't found one, I wouldn't go looking for it.
In the market if you search pixel, there is something called dead pixel test or something like that. It cycles through different colors. The most popular culprits will usually show on the black screen.
Go into a dark room and turn the brightness up. What you usually will see are bright white spots on the black screen which would be the stuck pixels.
Only the strong hearted and non OCD people should do this....Although any OCD person probably won't be able to control the urge to search for it now.

Got my transformer, two small bright spots on the screen

Two small pinpoints of white light on the screen. Are these dead pixels? Stuck Pixels?
I'm guessing that either way I should exchange it. So, apparently Asus is going to be having quality issues?

No dice. Thanks anyway.
Guess this bad boy is going back...
I got a replacement Prime yesterday and thought everything was perfect until I opened my web browser to google, which is pretty much all white and noticed a bright spot like you are describing in the title. Mine are definitely NOT stuck/dead pixels. I know because I returned my first one in part because of stuck pixels. It's almost like these pixel(s) allow slightly more light through than the adjacent pixels. Sort of like light bleed but not at the edge of the screen. I can only see it on white or very, very light backgrounds. It disappears entirely on darker colors.
It is unfortunate but I will not replace this again for a third time. It goes away unless my Prime is charging or docked (which I assume is because it is similar to the tablet being plugged in) and can only be seen on an all white background. I will never use my tablet plugged in, I charge it at night when I sleep, and the limited amount I have it docked is not an issue since it only shows up on an all white background and seems less noticeable than a dead/stuck pixel. Honestly, a smudged screen is more noticeable/annoying. Since I don't use my dock much it will probably end up having a dead battery anyway which means I really wouldn't see it much, unless the battery in the dock is required for it to function while attached, I'm not sure but will find out. Thinking about it I guess it probably does need to be charged for the ports and everything to work unless it leaches off the tablet. Who knows...I'll test it at some point.
It is kind of strange though and I really dislike trying to justify a flaw to keep a $500 device but whatever. IPS screens have some nice benefits but they seem to have a lot of flaws too like bright spots, pretty bad light bleed and more stuck pixels than I am used too. I went back and forth in my OCD head so many times about how many times I would exchange or return this device before I get one that is pristine but if I return it there is nothing else that interests me.
Asus had quality issues with their past Transformer and to think the 1080p tablet will be any different is ignorant.
Anyway, end blog. Since that's what XDA is now

If it's only 2 pixels and they are not directly adjacent, it's unlikely that they will take it back as that is deemed an acceptable tolerance for dead/stuck pixels. I think you need to have 5 or more total or 2 directly adjacent.
Pretty much all manufacturers use this guideline I believe. I hope I am wrong and you do get to exchange it.

I had one dead pixel on my Xoom and Best Buy replaced it without even turning it on to verify
I had two stuck pixels when I first got my Prime. Running pixel fixer apps didn't fix the problem. However, both of them have "unstuck" themselves after a few days of use. If you have some time before you have to return it, you may want to wait a little.
EDIT: Check that. I just ran a dead pixel test and only one of the two unstuck itself. The other one is so unnoticeable to me that I haven't seen it.

Same issue here, bottom right of the screen, small patch of white light in the browser window about an inch from the corner..
Not sure whether to return, the rest of the tablet is awesome!!
I just got another one and about 7 dead pixels the kind you can see on
Black screens and also slightly a bit of light bleed where the headphone jack is

what to check on the Nexus 10 to ensure it's perfect

Hey guys, as we know, the very first batch of any device likely will have some flaws. Hopefully this won't happen to the nexus 10. Anyway, Im a very picky consumer so I have to ensure my device is perfect. So I will list some of the things we need to check when the item arrives. feel free to give tips etc..
1/ Check the screen to see there are any dead pixels/ discolored area/ uneven white screen/ yellow or pink spots
2/ Light bleed
3/ any scratch on the body
4/Buttons are all good.
5/ Speakers
All I can think of so far..
also would want to check if the cameras, radios, ports, battery and other such components work properly, along with checking along the seams of the tablet to make sure it is solidly put together.
Microscope... check EVERY pixel.
I also have a few questions. It has to deal with the snap on cover if anyone got those (if they are out). When you unfold the cover does the screen light up like the iPad does with its smart cover. And also can the cover be used as a stand or does it just fall over? And how bad is the lag on Chrome compared to anyone who has used Safari on an iPad. Thanks. I'm hoping to switch from my ipad to the nexus 10!
Add couple more
1. Check GPS
2. Pixel check can be done with https://play.google.com/store/apps/details?id=com.ossibussoftware.deadpixeltest&hl=en

Well in my case they'd be replacing the screen whether they intended to or not. If I had to, I'd just order a new one, then send the old one back in its place and say I changed my mind. And that just if they didn't want to exchange a clearly defective product. Up to them, but either way I'm going to make it right for myself in the end :good:
With 2560x1600 x3 sub-pixels (=12.288.000 pixels) you will very likely not get a sample without a single defective sub-pixel. Doesn't really matter either, a stuck sub-pixel at 300 DPI resolution is so small that it will be hard to find even if you "know" where it is.
My tab 10.1 and GS3 first batch were flawless. I expect a pretty close to perfect initial batch here as well. This isn't Asus or HTC.

It's not only about the company behind the product, it's also about math/probability.
Hint: Try counting the sub-pixels on the Galaxy 10.1 or S3 and compare to the N10.

not really...I guess it's a matter of luck. I bought my S3 in june and after 3 replacements, I got the satisfying one.
One thing concerns me the most is the screen. It's true that it's hard to get a screen without any dead pixels considering the huge amount of pixels. well, I really hope this won't happen since if I ever find out just one single dead pixel, it would turn me off really bad even if I normally can't see it. But you know, it is there... haha

I forgot to include the legendary GS2 as another first batch flawless device. It might be about luck sometimes but generally you can deduce when it is safe to buy a first batch.
I use two methods that I feel pretty good about.
One, like I said, my GS2, tab 10.1, and GS3 were all flawless first batches for me. I realize that using just myself as a sample size is pretty shady statistically but if you look at the posts of complaints of the GS3 in May/June, they are far less than most devices.
Two, we know for a fact that Samsung is not only a manufacturer, but one of the if not the best manufacturer. Sure HTC and Apple are moving away from them, but it is not because of the quality. People trust their factories and manufacturing processes so unless the Nexus 10 uses some fancy new manufacturing process, Samsung already has the wisdom and experience and chances are, they won't need to make many changes to the manufacturing process like others might.

I'm not so sure we should expect the majority of units to have dead pixels. I deal a lot with high resolution 2560x1600 computer monitors and very rarely do I encounter dead/stuck pixels. You're right that they would be harder to notice because of the high pixel density, but I'll use pixel checker and send it back if there's an issue. Just because it's a smaller screen doesn't mathematically necessitate pixel issues. The 13in retina macbook pro has almost the same pixel density and of the few I've tested, none have any pixel issues.

Are you really spending maybe 15-30 minutes (if that's enough) to check each display in a dark room with dark-adapted eyes?
I'm asking that because as an example my Nexus 7 has 1 stuck blue sub-pixel almost smack in the middle of the screen, I know where it is and I still need about 10-20 seconds in a dark room with a (mostly) black screen to find it again - in daylight it's just plainly impossible to locate it. On a Retina/N10/WQXGA display this will be even harder.
It's my personal opinion that a lot of the people posting here how their displays are perfect with zero errors just never see any of their stuck/dark sub-pixels. They're really that hard to find unless you have bad luck and get a completely broken pixel or a cluster of broken sub-pixels in close proximity.

Whatever brings more happiness into your live ...
My personal view on sub-pixel errors is: if I have to search for them to see them ... I don't really care about them.
A full stuck/dark pixel (or anything that catches the eye) is a reason to send the device back though, no doubt about that.

I tend to do that anyway for light bleed... That's my worry. My Nexus 7 has pretty bad light bleed, and i'm okay with that because it's a cheap tablet, but I won't be happy if the Nexus 10 has bleed like that one. I can deal with a minor amount around the edges, but it's really annoying if it extends to the center of the screen, etc.

Not really true. My monitor is 2560x1440 and I promise you, there are no dead pixels. Granted it's 27", and the Nexus is only 10", it may be a little harder to see, but throw up solid color backgrounds and you will probably see it.

display dead?

Hi. I have noticed a small dots (a lot of them) on my screen especially prononuced when the background is black...has anyone seen this yet? I am still on 4.4....
Looks like a chunk of dead pixels.
Did they just suddenly turn up? If you didn't mess with your tablet, this should be covered by the warranty.

Hi. No i am extra careful with my tablet and despite being an year old it is like new...and not rooted everything is stock...i didnt noticed it until a few weeks back but it is difficult to notice it because it has to be black background...but they dont look like dead pixels as they emit a different color in games...very odd...it seems i will have to contact a repair center or i might wait for lollipop to see if it will magically fix it but i doubt it
It's quite common. Send it back to Sony. There's a thread about it in the help section that I posted in
Had the same issue here. It took 4 days including shipping.
On the bright side, you might end up getting a new tablet
Looks like you have a galaxy forming inside your tablet. Keep an eye on it, if you see the specs disappear from the center of the cluster, it means you have a black hole growing in it, and you need to take the tablet to Mt. Doom ASAP.
