Dead Pixel on screen - Xperia Z2 Q&A, Help & Troubleshooting

Hi guys,
Today during looking at facebook, I noticed a dead pixel on my screen.
Only one but still visible, it's a small grey dot on white background and other colors.
I restarted the phone and tested screen via service menu.
Does Sony accept this stuff to fix under warranty?
If yes, will it be free?

In general, warranty (of any manufacture) accept this only if it is more then 2.5% of screen area affected.
Since its only one dot, it will not be under warranty,

[Q] Found dead/faulty pixel on screen of sk17a

So I noticed a dead/faulty pixel on my sony Erricsson Xperia mini pro sk17a night. On the most bottom, right part of the screen of you look at it portrait. This pixel flashes whenever I scroll down webpages nut flickers often even on the home screen. Either that or its really dim. It's just one pix I think.
So is anyone else getting this or just me?
Also, to fix this I go to my phone service provider to get it fixed right? Since its Rogers and it said they will fix it for free or something. I have not rooted or done anything to void the warranty.
Exactly the same problem.
I have exactly the same problem on SonyEricsson sk17a . Did they fixed it ?
There's a screen test on service menu: dial *#*#SERVICE#*#*, go to Service tests and test Display. It will go to a color every time you touch the screen, press back to exit. There you can see if its a pixel problem and wich color the pixel is stuck in (or dead).
Then you can take it to SE for repair (warranty of course).

Yes I would do the same.
10x.I'l give it a try.
I also contacted with SE's support. Just waiting for there reply ( to be honest it looks like a software issue ) . When there is static image on the display , it is OK.
Hello guys,
So what happened finally with that issue? Was it software problem finally? I have the xperia Mini ST15i and there is a dark pixel on the very left of the screen and it's only visible when there is motion, but not in static images of any color!
Please tell me what happened with your case.
Thanks!

Make a test in service menu as said some posts above.
If pixel is indeed buggy, take your phone to shop, should fall under warranty.
Its the screen's issue. If im not mistaken companies keep the 5 dead pixel policy. Not subpixel, but pixel.
If a subpixel is faulty (i think) you cannot see one of the three RGB subpixels, If the whole pixel is faulty you get a white dot where the pixel should be. So from what i understand you have a faulty subpixel, therefore the company itself wont hold it under warranty but your Service Provider might.
Pixel problem .
From the support center here in bulgariq , they told me , that they will forward this issue to SE .
No response till now . My problem was ( and still is ) identical . Pixel is OK on all the colors, except when there is moving image ( than it is not , white , gray or some other color .Than the pixell i just black (dead) )

I think I have the same issue, my pixel is ok in all colors, but when there is moving image (for example scrolling in browser) even in white color, there is a dark dot flashing.. when the scrolling stops the dot dissapears too!
Is it the same as yours?
dead pixel
Exactly the same behavior.
Same here... A pixel in the bottom of the screen, it works good, but when I scroll, the pixel turns black :S should I send it for the warranty?

Dead pixel issue
Try to send it . I wil contact them again and will try to point the problem more precisely. It is strange. It is not dead subpixel because it shows all the collors correct. I think the display controller is not OK. not the display itself.
so do you think that is the display driver? Or perhaps the build 0.62? Do you think that's good idea to return to a previous build? Is it possible to fix the issue?
I mean it could be graphics driver software issue as well.

Androids do not have such problems. At least never happened any problems with graphic drivers.

I mean its not the screen for sure because this flickering pixel is only obvious in scolling for example.. also its located on the very bottom of the screen. its close to the XPERIA logo and light on the right. if the refresh rate is high it flickers fast so its difficult to see it.. when its static image there it dissapears..
Ofcourse it is an issue of the screen... You have a faulty subpixel. Maybe on non scrolling occurences the color is stabilized with the remaining 2 . This isnt windows/linux/mac, you dont upgrade drivers as you would on a computer. And no its not your GPU. If it were the gpu it youd be going haywire in random parts of the screen not just a specific 1x1 pixel area

To be honest I don't know if its a subpixel thing.. For example when Safari is loading, even on a white page, this pixel is flickering. When it stops loading the page, the pixel dissapears..
Have the same issue with my Xperia Mini ST15, I have a stuck pixel in the middle of screen (yes... that sucks) but it's only visible when the screen is showing a black color, its a shine pixel.

Stuck/Dead Pixel

Hey guys,
in the last couple of days I noticed that there are quite a few 30-50 dead or at least stuck pixels on my screen. It really bugs me, because I'm kind of a perfectionist. They are all in the same color. It's a light grey or white. Due to that they're only visible on black surfaces.
Is there anything I could do about this? I already tried to run a stuck pixel fixer, but nothing changed. Ran it about 10 hours. Is the warrenty covering this? My phone is unlocked btw.
Hope you guys can help me. Thank you!

Basicaly Yes, because you had more pixels than the minimum requirement for most of brand or trademark
but you must notice two thinks, first the phone must never to be drop or schoked or any trace about user damage.
Second one, Normaly the phone lost all waranty if you unlock it but normaly if you put the phone with the stock recovery , stock rom and lock again the bootloader, that should be ok for the technical support.
Same here matey, allot of dead pixels around the vertical edges of the phone. I had it checked out and people tell me it's dust. I did get a nod from HTC to send it in for repair. It's covered by warranty

I notice today, it's ghosting is not that much but I can see the lte signal bars and battery icon while using the phone in landscape
I have the G5,and I have backlight bleed along with icon burn in. I called,but the only thing LG would do is fix my phone and it would take a month. I can not do that,I need my phone for work. Why can't I just get a replacement ? From what I've been reading its a fairly common defect with the G5. Any advice on how to deal with them ?

My burn-In started today, usually the status bar was Burning, In a couple of hours now it is starting to burn anything that stays a couple of minutes on screen.
Now it has Status bar along with Nav Bar and anything that stays on screen. This is starting to piss me off.
Plus it fades away if I leave the phone intact but has soon has I start using it the problem persists.
What does screen burn mean, please?

Means that after certain time of having an app open or given the situation status bar or Nav bar starts to have ghosting or clear images of something that you haved opened on your phone. You can see this images with a complete grey image if they are soft. If they are burning really bad you can see them from any dark colors that you have on your screen.

Manufacturing Defect?

Just got the new Redmi Note 4 (64GB+4GB) yesterday and spent half my day setting up the phone and transferring all of data to it. Some time late in the night I did a reboot and while the phone booted in the first boot screen that is, a completely black screen with Mi logo on it, I noticed a few coloured spots ranging from the bottom of the screen to the top. Once it booted up, I went into the gallery and opened up a completely black wallpaper, turned on the brightness to full and zoomed in the black portion of the wallpaper and again saw those spots at the exact same place.
Is this a manufacturing defect?
Thank you for your help.

Have they gone away? The screen is known to have temporary burn in that goes away after like 5 hours
I also noticed these spots on my screen. Is it a hardware or a software defect? If it's a hardware defect, Xiaomi should address this asap. I can't have a brand new phone with burnt dots on screen.

Just checked again and there are still some spots. Majority of them seem to have gone away. Will check again in a day or so.
I don't have any spots on my screen at all.

Have you flashed any Roms since you got it? Could you be running a buggy vendor/reseller ROM?

Haven't flashed anything yet. Got the phone yesterday. Contacted Xiaomi service centre, waiting for their response
dead pixels. xiaomi phones have always had dead pixels at least in all the phones i have used. redmi note 4g, note 3, mi4, the 2 replacements for redmi note 4g all had 5 or 6 dead pixels. sometimes they are not visible until you forcefully try to look for them. 1 or 2 dead pixel is fine and i used to freak out earlier but now i have accepted 1 or 2 dead pixels whenever i buy a cheap phone. only my mi pad had no dead pixel. almost all brands have 1 or 2 dead pixel and that can be ignored but more than 5-6 can't be ignored imo.

No, they are still present. I actually don't have a lot of time to go after Mi for a replacement. But I might go and talk to Mi service centre this weekend
Stuck pixels spotted
Hi
Even i have more than 30 stuck pixels,
some are small and 4 pixels are big among them and they are Cyan blue colored.
Same problem here. But my wife's phone doesn't have it. Same model
Please raise a complaint to Xiaomi and get it replaced at the earliest. Sounds like dead pixel issue.

Dead Pixels on the screen

So after month of owning this phone (SD version), yesterday I noticed that there was green pixel on dark backround. After a while of looking at black picture with max brightness, I noticed several small red-blue-green dots all over the screen, which weren't visible on other backrounds. I have already sent it to repair centre (free screen replacement). I just wanted to ask, is it frequent problem with RN3 or I was just unlucky? Is there any side effects of replacing the screen?
I'm using this device for about 6 months now and i haven't seen even one dead pixel in my phone till now, but I haven't noticed even one dead pixel on the screen till now...
So, I guess you were unlucky and your device had this problem...

Can you check it on dark room, with dark backround and 100% brightness? Just want to make sure Also, I think I was unlucky too, I hope replacement screen is better.

I have rn3 sd version.
and I noticed 3-4 dead pixels on the screen
it cannot be seen on regular usage. hardly can be noticed when lcd test (dark screen full brightness)
I think many rn3 phones have same problem. many users just have not noticed yet.
it's common and expected, for the price you won't get the best panel, i also have 2 stuck pixels, one green and one red
Yeah I got one too and maybe 2-3 more...but not visible in normal usage.
Happened after like 5-6 months.
hmm, it seems that many are having stuck pixels, mine just had too many and it's free screen replacement anyway, so Thanks for replies guys.
I bought it from china so hope it works well long enough...its not an option to send it back

I couldn't spot any dead pixel on my phone....
I guess I'm the lucky one then:fingers-crossed:
Some of my friends have the same device and they also don't have any dead pixels...
Well, see if your replacement panel also have the same issue...
Edit: I don't think that's a kernel bug as many users including me are on Radon and none of them reported this issue...
I have a unusual red fingerprint that barely visible on the bottom part of my screen.
You can only see it on still black screens and you will have to look carefully to see it.
It is a comment problem to LCD screen my all phones have dead pixel except Redmi note 3

Yeah, I'm pretty sure thats not kernel related (I haven't flashed any custom kernels anyway). I hope replacement screen will be good.
I had a orizontal green line at bottom only on miui.
On aosp doesnt exist.
My phone has several blue and green patch, when I purchased never noticed it till 1 month. After that I got screen replacement when I visited service center, Now my phone creeks.. If grabbed hard its back panel creeks.
I don't blame, Its a cheap company and cheap phone. But performance is good.

Creaking is actually common on RN3. Althought mine didn't (well, I was using a silicon case) and I don't think screen replacement did that, unless service center did a bad job at it.

Actually back panel is rubber glued. (The speaker and upper panel) I think when they open up phone, for screen, they removed rubber glue, so now it creeks against plastic..
