Dead pixel in screen?

So I noticed this when I bought my tablet and tried to disregard it but after 2 weeks its starting bother me. I'm pretty sure its a dead pixel and trying to decide if I should bring it back to office depot and ask for a new tablet. What do you guys think? I posted two pictures to show what I'm seeing. On the first picture, its right by the N in education. I know, probably seems picky but when I'm on a white page, its pretty noticeable.

Well, if it bothers you then you should return the tablet and get one that doesn't bother you, simple as that. I also have a stuck pixel on mine, but it doesn't bother me at all and thus I won't be returning mine.

a white pixel (stuck on) I would definitely return.
I have two miscolored pixels on mine that chose to not care about. It's common with TFT screens..

You can fix it........unless its a grey or a black dead pixel......massage it hard and try to move it towards the nearest side the effect is not instantaneous.......use an app called pixel fixer.....leave ur tab on charging while using that app......do both the methods and it would be gone in a week.....(worked for my phone)....

That's a horrible recommendation for an LCD that sits behind a gorilla glass touch screen. Unless you tell him to take the gorilla glass digitizer first he'll be risking breaking the digitizer before he ever gets close to the lcd!

Rubbing the screen doesn't work on devices with real glass displays, especially not gorilla glass. That method only works on displays where the glass is flexible or malleable (like computer lcd monitors or earlier/older phones).
To the OP:
If you're brave you COULD attempt some very gentle finger taps right above the area. I suggest trying to find a software fix though. If you try and try and it still sticks, then go ahead and return. I couldn't deal with that on my screen either.

Exchange it for another one NOW. You paid for it. You should have nothing less than a good screen with no stuck pixel.

Sorry to read this.
I'm the guy who's windshield and glasses are never clean enough, so a dead or wonky pixel would drive me nuts.

Thanks for the suggestions but I ended up just taking it back. Like a few of you said, I paid for it so I expect it all to work right. They took it back no questions asked. All is well in the new one

[i9023] SLCD screen bends under glass -> yellow stain

last night i was surfing some pages, when i noticed a yellow stain/spot at the right side, near to the top of my screen.
this morning when i looked at it again, i frist thought it was gone, but after some usage, it came back.
taking a closer look, i saw, that the slcd foil(?) under the glass has bend a little bit, what seems to be the reason for this yellow stain. i think it might be a heat problem, since it was gone this morning, but came back after some usage.
i also think it might have to do with using navigation, since my nexus really gets hot while using that.
anyway i will bring it to the shop, but i'd like to know if there were others experiencing this..
here two pics attached (the stain can't be seen that good on a picture).

You sure it wasn't dropped?

yeah, in all those 6 months, that i have it, i never dropped it.

I've also 2 yellow stains,on the left and the right of the lcd on my slcd i9023.I guess it has something to do with heat,because in winter when I've bought it ,it was ok,now in summer the yellow stains appeared.Next week I;ll send the phone to Vodafone service in my country,and I hope it will be exchanged.
Best Regards

That sucks. I hate dealing with hardware issues. Good luck getting it fixed.

After 1 week in service,today I've received back my Nexus S i9023 with a new slcd fitted.No more yellow staints,I hope it will remain the same a few month at least.
Cheers

hello, I am also having the same problem, the same yellow stain has appeared on my right side but i don't have the "warped" lcd as in the first photo... It is definitively a heat problem because i noticed the "stain" when i was downloading on wifi while plugged in and that part of the screen was far hotter then the rest of the screen...maybe some chip under it running hot.
The thing is i got the phone new 6 months ago from ebay so no warranty and my concern is, what guarantee do i have that after i change the screen, that the problem won't appear again? Does anybody know if there is a fix eighter for the screen now or something to prevent it from happening again to my new screen? Could it be a manufacturing problem of the screen itself?
It doesn't seem that this issue is common..Also does the spot spread?
Thanks for taking the patience to read and for any answers.

Today I noticed the exact same problem in the same part of the screen, and I also noticed the foil being bent at that part of the screen. Its perfectly visible under a certain light angle. Being on the exact same spot as your problem, I suppose that it is some chip under that part of the screen causing the problem. I think I also has to do with the fact that the screen is curved... anyway, I cannot return mine for a new one, I hope people in the local service shops will be able to provide me with a fix. Too bad that such a cool phone like the Nexus S suffers from so much problems (I also had the proximity sensor problem that caused screen to remain black sometimes when the phone rings without a way to see who is calling). I will go for one of the new nokia handsets.

Another one here with the same problem on the upper right corner...
I have the phone 8 months now and I am sure that yellow stain wasn't there from the beggining but now it's quite visible especially with white font for ex. when browsing... Also in a specific angle the foil of the screen in that place is visible too...

Same problem on the right corner on top. If its in guarantee they will fix it for free?

now after having my display fixed last october for free, since it's a known issue, i actually got a new stain after a couple of months..
but this time, it's on the left side and much bigger.. time to send it in again, warranty till next february..

I have the same issue, I am planning on getting it fixed as well. Good to know that it's a known issue and it's covered.

Same here, upper left corner...
Disappointed to read replacement parts are defective too...

exactly the same issue on right top corner, I sent my phone to warranty repair currently...

Top left corner here. Just hope i can find my warranty or else Im screwed..

Unfortunately i have just seen the same thing that's happened on our nexus s on my friends galaxy nexus.. i was planning to get one after my nexus s developed the spot but now i'm not so sure anymore..

Center left... the same problem!

upper right corner here. Noticed it in some very hot days that are passing now in my country. should I send it to warranty?
My worries, I got the phone in a promotion (huge discount) afraid that if I returned it they will give my money back and I can't get any similar phone for the same money (I really like/need this device)... in the other hand, it might get worse than it is and unusable

Are you guys running custom kernels?

Nope

Or exchange it...it is very common on GS2's and Galaxy Nexus...I've seen people post, they bought a Nexus from Google and they have gone through like 5 getting one that doesn't have the dark blotch problem. Some GS3's have it too, mainly international versions. If you got a bad one, take it back...run LCD Test and show it to them, they have to exchange it.
It's something with the glue not drying inside the digitizer/glass assembly

one of the reason why I have not bought a galaxy s3. I don't want to play the exchange game.

im like that too.... but this defect doesn't bother me as much since it is on ALL phones..regardless if people say they don't have it...they are lying or not testing it properly
it's almost like a guy who says he never masturbates....yea right! :laugh:

Oh crap.. i was thinking of exchanging my unit because it came from factory with a small hairline nick/scratch on the area above the line sensor. Everything else is mint except this part and it annoys the hell out of me. However, I don't have any small black marks nor blotches on my screen. I just tested with LCD Test and it is perfect. Now I don't know if I should exchange it now for risk of getting a bad lcd :/
Would you guys exchange it if you were in my position?

You have to use lcd test on black with maximum brightness, you have to be in nearly complete dark, and you have to let your eyes adjust to darkness. Otherwise, you won't see them. Even the capacitive key lights are bright enough to wipe them out.
It's really a nonissue, unless your phone is defective. Some people's phones are really defective, and they are even able to take photographs of those.
Normally, there's no way to see them in any real world use.

Touchscreen dead strip!

I've noticed just today that there's a dead strip on the touch screen. It didn't do this yesterday. The Nexus 4 was dropped once from 2 feet high, but that was almost a month ago and everything worked fine until now.
The screen still looks beautiful, no dead pixels, no cracks, and the phone is in a protective case with a screen protector.
It seems to me that the digitiser crapped out, but I'm not sure why it happened so randomly.
A funny thing though is that when I drag something fast across the strip it works. And sometimes it'll recognise a touch as a long touch or two-fingered touch along the strip. Weird.
I attached a few touch test photos to show the issue.
Hopefully there's a fix. Has anyone else had this problem? And if you had to send it back to Google, was something like this covered under warranty? What should I do?
Sent from my Nexus 4 using xda app-developers app

You can try to replace the screen yourself or tell LG/Google to send a replacement via RMA. They have parts floating around Ebay

How risky/costly is it to replace it myself? And does anyone know if it's covered under warranty? Cause if is, it'll be cheaper just to get a replacement from Google.
Are there other ways to check if it is indeed the digitiser? I've seen that sometimes touch screen problems are software related. And if that's the case, it'll be easy to fix.

And .... Out of curiosity, what does cause a digitiser to fail without the screen actually breaking?

Depends. If you follow the instruction properly, it works well. If you screw up, then Google/LG wont be able to help. A lot of people have done it and succeeded. There are great articles on the web. The price of a digitizer would be about $50-70. I MAY BE WRONG WITH THE PRICING.

In most cases no. Because it worked well and suddenly stopped working. Thus Google would say that its your fault. If you are somehow able to convince the Reps that it wasn't your fault, then there is some hope. I

Anything. The phone might have overheaten to the point that it flashed a certain section of a digitizer. It may also be a battery problem that escalated. If you feel that it's software problem, flash a ROM a see if it works.
IMHO You should send it to LG and get it fixed for about $140~.

This problem should be covered under warranty. If you honestly haven't done anything to cause this damage. (I'm also clueless as to what a user could do themselves to make just one section of the digitizer stop working)
Then lasting 5 months or less would not be considered reasonable and you should be entitled to a replacement.
Remember it is down to the retailer to prove that you caused any damage.
And if you honestly did nothing and it just crapped out on you then you should have nothing to fear in sending it back for a warranty replacement

That happen to my iphone when it got water damage. But if you did not do anything wrong, it should be covered by warranty.

Same bug here in Italy where I'm living now even if the the phone was bought last year on UK Play store. Problem is Google rep wrote me RMA can take place only in UK or any other county where N4 was originally available on Play store i.e. NOT Italy.
Does anybody know of a workaround to get the RMA here?

Yeah, I think the overheating might have been what happened to mine. I was using a blackberry charger and I think it might have overheated my battery and fried a strip of my digitizer.

Even i have got the same problem, i dont know who bumped this old thread, but please guide me to for a low cost workaround for my situation
No drop or glass break.. Dead pixel just one..

Hi,
Anybody found the reason for the issue, i too got the same issue; a dead strip exactly in the middle of the screen, My warranty is over already, so anyone has work around for this??

This looks like a dead thread, but Ill take a punt. I dusted my old Nexus 4 off the other day, which had exactly the same issue with the dead strip on the digitiser. I had tried replacing the screen and digitiser (I have up trying to get the original screen off the original digitiser). The issue remained, so I tried a full factory reset, but that also didn't work. I am now wondering if I should get a cheap motherboard, or try flashing the stock ROM again. Has anyone else had any luck with either?

[Q] Nexus 4 dropped and display blurred,

My Nexus 4 dropped from my pocket this morning. I was shocked but the Phone didnt switch off. No visible scratches,apparently there is no scratches at all.The Display turned blurred and there are green,red and yellow patters visible from top to bottom on the left and right sides of screen.Advise me what to do next .The display is looking like running a 800*600 resolution on a 1920*1080 screen.I want to know If the LG customer centre accepts this under warranty.I didnt contact them. .

This is just a wild guess, but something inside probably came loose due to the shock. Take it back to LG and tell them that you don't know why this happened. I am pretty sure that drop damage is not covered.

Warranty doesn't cover accidental damage

can they find that it is dropped

My query is will they be able to find that the phone has been dropped, because many users reported this issue in a brand new device. Proper context for the problem is vertical patterns appearing and the display is blurred.

Service centre people accepted it

I cannot understand what you are trying to say.Is your colours alone changed? My device resulted in vertical patterns of lines appearing on the display and the display is blurred.If the colours alone changed means you can re adjust it with display control,but better is go to service centre because there are chances of that happening again are quite possible.Some internel parts like the embedded digitalizer might have been became loose due to stock.If your phone has no visible scratches or broken glass,then you can go to service centre and say to them that "i dont know why this happened".
