Dead Pixels - Xperia Z2 Q&A, Help & Troubleshooting

Has anyone found dead pixels on their Z2 got mine Saturday and already had it replaced once for this issue and the replacement has the same problem

Cant find any dead pixels on mine. Come to think of it i always got lucky with stuff like that. Not a single dead pixel on any device i ever had.

2, one really noticeable, one is faded

Sony warranty states that 2 dead pixels are acceptable. Fortunately, my Z2 has none.

I've sent mine back for a replacement with one dead pixel and overheating issue. Bought it last Friday, already gone

I found one dead pixel on mine, but I'm ignoring it for now.

OK. I have one stuck green pixel on the top right. Is this a common thing with xperias? Does anything actually work to fix them? My phone is ULB so I can't get it replaced.

Try display tester pro. No guarantee but worth the try

I had a Z replaced at least a dozen times due to dead pixels, eventually got a Z1 which had none but now it looks like Sony is plagued by them back with the z2

I've tried a few apps to fix it. Its only barely visible when on full brightness with a black background when its close to my eyes. No biggie.
Is this pretty common with Sony Xperias?

Every phone manufacturer suffers from these problems not just sony, I remember it was a common problem with the nexus 5 when it got released, if it's only 1 dead pixel then it should be much of a problem, besides I have heard you need at least 3 dead pixels to get a replacement

do you guys check for dead pixels with a magnifier? As now with these high dpi screens it's pretty hard to identify "one" dead pixel to me... maybe mine has but i don't think i can notice it without a magnifier lol

I only noticed it on the black screen in the dark. It doesn't bother me, it's only one pixel.

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.

+1 and you work for sprint. I work for a bottled water company. If I got a bad bottle or my cooler wasn't working correctly I'd want it replaced asap.

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.

A pixel of my Galaxy S2 just died...

Ok this is like the 5th fault I have with this phone and I am almost all over Samsung. A dead pixel suddenly "appeared" on my screen. At first it was all nice but now checking *#0*# and clicking the green option the pixel is just dead(black) on red/blue I don't have this problem. Still on all backgrounds the pixel seems like red(especially on white backgrounds). I have photos(taken with DSLR) that show that it didn't have a dead pixel at first... But now it suddenly popped. Any good reason for this? I've had the phone for only 3 months.
Probably running the phone too hot for too long, just claim it on warranty and attempt to get a Korean one thye are better than the chinese version.
it's korean... and it's driving me mad..
If **** happens, keep getting it replaced. Hopefully then Samsung will learn about quality control LOL
not a tech or advanced in knowing about these kinda things but have you tried taking it back or speak to someone at a service center of Samsung near were you live?
your under warranty so check it out

send it back were you bought it from...or call samsung customer service and get a reference number and send it in...your under a year warranty so your not paying anything for it at least you will get a new screen or better yet new replacement
Nooo, mine JUST developed a stuck/dead pixel.
I tried Pixel Fixer... no luck. :/
Once I had a dead pixel on my iphone I know, but well.
What I did was to "massage" the part of the screen where the pixel was dead. Not hard of course, but strong enough to make pressure.
It could be that the screen lifted a little.
It worked for me.
I have had some success on notebook screens doing that, but the S2 has a solid glass screen and it will not work, as the faulty area need to be pressed.

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?

return son!
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

Nooooooo dead pixel :(((((((

I thought I was in the clear with prime issues as I had none for over 3 months but I just noticed today I have 1 dead pixel (( its only noticble in whiteish backgrounds but its really annoying and I can't send it back cuz I've had it since the beginning of January. I can't even see it in non white backgrounds though. Is it even possible to fix this because it just happened today? Also by serial number starts with b not c so its one of the early models

There are a couple of apps in Google Play that might help. They play a pattern of shifting colors repeatedly over either the entire screen or a small area. This can sometimes help, although I think it's more common for stuck pixels (i.e., those stuck showing a single color) to be fixed compared to dead pixels.

I second this! Pixel Fixer on the market did the trick for a stuck pixel I had on mine.
Well the pixel only shows as the colour white. also pixel fixer didnt work
Are you sure it isn't LCD mura and not a dead pixel? Do a quick search for LCD mura and you'll see what I'm talking about. I have LCD mura, which is only visible on white backgrounds, and it appeared after a few months of ownership.

Well i dont think its lcd mura. Its a pixel upon whiteish backgrounds that shows up contrastingly to the white. Under other colours, its very hard to notice but it is still there

Man! I noticed the very same thing while on holiday last week. Couldn't believe it.
My Prime had 3 dead pixels out of the box. It's a C3 and other then the pixels the device functions flawlessly...I'll probably just wait and see if anything else goes wrong as I don't plan on unlocking the bootloader anytime soon.
Got mine right before the year end or around that time, one of the first models. Just noticed today that it has some stuck pixels, a few in a spot somehow. Trying some pixel fix apps, but it might be stuck. Damnit, need to RMA already? It's 3-4 months old...this is why I didn't want to unlock the bootloader yet. Asus quality, I've done nothing to the tablet to make this happen, yet if I had the unlocked bootloader they would have blamed me and probably not fix it since it has a void warranty. Even though it seems like a hardware defect. Stupid.

I also have a similar issue with mine, 3 bright pixels that only show against white backgrounds. I am waiting till they get these devices more stable before RMA, which everybody should be able to do even if you get it in January, since it is covered under the hardware warranty.

Dead or Stuck pixel?

So i have a bright (white) pixel on the screen...
It's really visible on BLACK and little visible on BLUE background ( not visible on Red or Green background)
the pixel's visibility does change when i change the screen brightness
so is this a dead or stuck pixel.... how fixable is it?
Sounds like a dead pixel.
Cant be fixed. If there is only one then they wont replace it. You're stuck with it(no pun intended).

I've got one as well but is only really visible above 50% brightness on a dark background. Unfortunately the pixel died about a week after I got my S but I've managed to ignore it most of the time. Having such a high pixel density helps a lot.

Too bad, I have been through 4 Xperia S phones. Two from yellow tint, one bad battery and my latest which has no issues. None of them have had a dead pixel, so I am surprised to see so many.

Is exactly the same to me, in the top of status bar (touch firmware 6, ABAE and 12w16). I hope to be the first and last ...
On my Xperia U I have one green stuck pixel. It amazes me the Sony quality control check. This is my third SXU. First one 4-5 stuck pixels, second one totaly dead and then this one with stuck pixel again. Sony service center and retailer didn't want to acknowledge the complaint. They told me that one or two defective pixels is acceptable.
as far as all my reading goes, the dead/stuck pixels are always claimed by manufacturers that these are "within specifications" whenever there's 7 or less on screens (TV, monitor)and 4 or less on mobiles (as their screens are small).
on my experience on TV though, you can forget about dead/stuck pixels if there's 7 or less. the most important thing to test is the backlight bleeding, check leakage of light on a black screen (that is screen is on displaying a black image). that is more important than few pixels which you will just neglect in time. the backlight bleeds, this you can never forgive.
now for mobiles, its very rare they would have backlight bleeds. so there, we can focus on the pixels. i think this would be more noticeable on large screen phones (4 inch up) or low pixels per inch density. from hereon, its best to test the phone before paying for it, display a black image for backlight bleed check, then colored and white screens to check on dead/stuck pixel. don't ever pay until you're satisfied. its very hard to return/refund/argue when you paid already and noticed the bad thing. unless it happens after you leave the store. so again, its best to thoroughly check it before paying, and of course fully warrantied.
