Defective Screen Help - Nexus 7 (2013) Q&A

So I had my Nexus 7 2013 for about 1.5 years. It was not until now, that I realized that there is a dead pixel in the middle of the screen. It is really noticeable in dark backgrounds, such as black. The screen just displays a giant red dot, very obtrusive. Since my warranty from Asus has expired, I was wondering if anyone knew how I can go about resolving this?

The information is a bit less to work out with. Do you have ghost touches or unresponsive screen in the middle or just dead pixels ? Add some more details and quote me back for a reply!
If you live in US, i have had from many people who delivered their nexus to asus and they replaced the screen for free actually. So give it a try.
Good Luck!

Hi,
The tablet still functions fine. Touchscreen and all works perfect. It is just dead pixels which show in the middle of the screen. I do not live in the U.S., so I am not sure how I can go about repairs.

I am afraid that is a hardware issue. I remember I got my nexus tablet in the UK from US on August 2 or 3. I had a bit of a defected piece. I wrote to ASUS UK and they replaced it for me and helped me fix it. Maybe you can write down to ASUS in your region and see what do they say and quote me back about it ?

What kind of dead (or stuck) subpixel is this?

I have an odd pixel right in the middle of the screen. When I run Dead Pixel Detect (which you can find in the Market), it is lit in the following ways:
- on a white screen, it seems red;
- on black, it seems black;
- on blue, it seems blue;
- on red, it seems red;
- on green, it seems black;
- on yellow, it seems red;
- on cyan, it seems black;
- on magenta, it seems magenta.
Does anyone know what kind of faulty subpixel(s) this is about? Is it a dead green subpixel?
I think it's just a stuck pixel because if it was black all the time, then it would be a dead pixel. Try JScreenFix from the Marketplace and pray that fixes it:
try http://www.appbrain.com/app/com.jscreenfix.android
Well, I'm sure that it isn't a dead pixel indeed but it seems to be a dead subpixel. :-( I already tried that JScreenFix app but it hasn't made any difference so far.

Technically, I think it may not possible for an AMOLED to get a "stuck pixel" like you would get on a normal LCD screen. The fact that you are getting a red pixel on a white screen, most likely means that the G & B (as in R,G,B) are dead.
Traditional LCD screens produce different colours by passing a charge through a kind of lens that twists producing different colours as the light passes through it. A stuck pixel happens when one of these lenes gets jammed and stops twisting, which is why you can sometimes fix them by flashing loads of colours on the screen rapidly, it sort of rattles the pixel loose.
If you've got a pixel that's displaying the wrong colour then it's broken rather than stuck.
I am not sure what else you could try to fix this... is it still under warranty? Realistically, I think having it replaced is your only option.
I have exactly the same problem a 'pink' pixel on the screen which is mostly visible on light backgrounds. Did anyone try to exchange it for this reason? I bought it from t-mobile UK.
I know that in the past they would need a certain number of pixels to be faulty before they would change anything (tv-s, monitors, etc.) Is this true for this phone?
If they dont then just say it has a different problem, most operators send out the replacement and pick up the 'faulty' one at the same time.

Thanks for the explanation!
Well, I bought it 5 weeks ago so it should be under warranty although it is rooted. I can hardly see the dead subpixel (even though it is in the middle) so I'm not really concerned but I might consider contacting HTC customer service anyway.

No problem bud, although, if i were in your shoes, then i would unroot it and send it back for replacemet while still under warranty. Afterall, you paid for a product that should not have any defects, and something like a dead pixel to the screen would annoy the hell out of me

Yep, I'll probably do so. The only thing is ... my Desire was Vodafone UK branded, and I unbranded it when rooting. However, there is no full RUU available for Vodafone UK handsets. However, in my opinion, HTC should not care about that since it's a hardware defect ... but no one seems to know their opinion about it.

[Q] Yellow screen burn at bottom of screen

Guys, over the past few days I have noticed at the foot of the screen in the centre there is a yellow line (approx 1 to 2mm thickness) appearing which looks very much like screen burn.
It can only be seen when a lighter colour is present but it is there no matter what you are looking at.
When watching movies it is horrendous as your eyes are constantly drawn to the yellow thick line.
Question being has anyone else noticed this?
Sounds like a faulty panel to me

Impossible to see if you do a screen grab. The grab would not show the screen burn.
The only way to do it is to take a photo of the G3's screen and I don't have another camera at hand with me this weekend.

No, it's nothing like a dead pixel.
It's more like a yellow stain that progressively gets darker the longer the screen is left on.
I contacted Clove who would send it back to LG for them to look at.
In the meantime if I change the Home a Touch Buttons to Black it covers up the Yellow stain whenever a screen uses the touch buttons.
It's when you are either looking at photos, watching movies or playing games where you don't have touch buttons displayed that you see it.

I have had this on devices in the past, its certainly a faulty screen.
Yes, I definitely agree on that.
Okay I should return it for repair but I would find it murder to be without the phone.
So far it is limited to the area of the touch buttons and like I mention if I change to black you then don't see it a lot of the time.
I'm seeing if I can live with it..........

Just as a warning, when I have had this on devices in the past it is something that gets worse over time, the yellow area will spread, its probably worthwhile getting it fixed now to avoid having it become a bigger problem in the future.
Have you spoke to clove yet? Surely they might just swap it out rather than force you to get a repair?

Yes I spoke with Clove and was quite surprised they would send it back for repair.
At the time I had had the G3 for 18 days.
As such seeing as being without the phone is going to be a nightmare and it's not spreading or getting worse for the time being, I'm mulling over my options.
Fortunately money is not a problem. If it gets that bad I would rather buy another and set up the new G3 in the presence of the faulty G3 then either give the faulty one away to a member of the family which I do with all of my phones and let them decide what to do....
I have the exact same problem. Found this thread googling for it. It's almost right in the bottom center. Looks yellowish and it's driving me nuts. I'll probably hold off exchanging for a while since I cannot afford to go without a phone and have no way to backup everything until someone unlocks the boot loader.

Well, if it's any help to you all I can tell you is it doesn't appear to get any worse.
Yes it's there and more prominant when it gets hotter but it doesn't appear to be spreading or going darker.
At the moment I am still living with it.

Dead Pixels

I have about 5...does anyone else have this issue?
I have 2 dead pixels
Pristine and unblemished here. Sorry for your loss.
I've got one dead pixel. Not too worried about it though.

I have another watch coming, I'm going to check that one and return the one with the most dead pixels.
One, but it just went away. Lucky me.

Haha no loss here...just seeing if others had the same experience. Thanks though!
Just picked up mine, one dead pixel.. Apparently the first batch is mostly defective
None.
I have 1. Google Play is in the process of replacing the watch. I reported it to them the day I received it.
Really disappointing to see this issue be so common.
i received two silvers from motorola today... two stuck green pixels on both, same mid/upper left location.
I have about 4 dead pixels, best buy is going to replace it. They ordered me another one and I'll just return my current watch when it comes in.
Numerous dead or stuck pixels all over. Just got it today, contacted Motorola (bought it straight from them) and got a full refund, a return label, and a 10% promo code to purchase a new one.
I had one dead pixel. Just returned mine yesterday.
So, a buddy of mine ordered ours together and we both wound up with dead/stuck pixels: His had 2, mine had 5.
We don't want to be without them and potentially get stuck waiting for a couple weeks, since we got the silver ones and they seem to be in high demand, but I think we might just have to return/exchange them. It sucks because if his Best Buy wasn't closing down relatively soon, we could hold on to our current ones until the new ones came in but they have orders to the store disabled meaning we'd have to return them right away and ship the replacements to his place.
This is why I rarely, if ever, buy first gen/first batch electronics.
Hmmmmm I have one dead pixel barely noticeable but it's there.. Tempted to exchange it but don't want more dead pixel there.....
None here, pristine. I'd go insane if I had dead pixels. Dead pixels are the worst to me. My eye gravitates to them every time. I have a few on my work monitor and it drives me insane but they wont' buy me a new monitor and its out of warranty.
I traded 3 total.... Every one had 1 or 2 idea pixel..... I gave up.....
So, to see the dead or stuck pixels is everyone setting the brightness on 5 and going to a black screen (such as the about screen under settings)?
When I do this, I see a few pixels at the top of the screen and one in the lower left that appear to be stuck? However, without turning up brightness and being in a dark room on a black screen, I see none. I also can't see the stuck pixels on any other screen except for the boot up screen or this black about screen.

After Repair Issues

Hi, I cracked the screen on my Nexus 7 (2013) and I replaced the LCD+digitizer. Now I have a big dead spot in the middle of the screen and it cuts out when I drag my finger across the screen.
Any help would be much appreciated!

This issue has come up enough times. Look for instance at THIS thread. There are so many possibilities as to why, it's impractical to generalize. In your case,however, I highly suspect the digitizer itself. But it depends on whether you replaced the combo, or the lcd and digitizer individually. While it's too late to mention it, you should've tested the thing before sticking it to the bezel. Some vendors would nevertheless consider a replacement if you can send it back to them. Good luck.

Dark stripe with low brightness

Hi,
I bought recently a new Samsung galaxy tab s4 and the first time I watched a movie laying on bed with the lights off (low screen brightness), I noticed a dark stripe on the screen...
https://m.youtube.com/watch?v=TqcpX6g0ciE
Well... Is this normal? I guess it's not. Should I return it?
Thanks!
I have this too on my Samsung Note 4. It is a common defect of AMOLED displays, where the temperature and luminance degrades the pixels over time, increasing the probability for burn-in.
You can try to find which app caused this, by matching up the dark area with the app contents. For me it was YouTube and 8 Ball Pool that I was using for long periods at full brightness --- when playing a fullscreen video or game, the screen will NOT turn off. I kept forgetting this, and went to the bathroom or kitchen leaving the screen on!
Did you buy it second hand, used? The previous owner or you may have likely used full brightness and showing a static image for long periods.
There is nothing you can do to fix it. The S4 is still a new flagship model so you may be able to get a replacement.
Well... I bought the tablet two months ago, brand new, and I have barely used it. Like... twice a week or so.
My sister has the same model, used it a lot more and it hasn't developed dark stripes.
I cannot find a match except, maybe, the Google search bar. I guess I will try to get it returned. I cannot accept this on a 500€ tablet. Should I know this before hand, I'd bought a Huawei tablet for half the price.
Or maybe I'm overreacting and I simply got a defective unit.

Thanks what was your brightness set at ? Man in the video link you posted the text at the bottom looked crazy bright ? On mine it looks fine please note i did move the image like you did my brightness is set at dead center on the second icon so about 25% or 30% ish (im guessing)
Also i set the brightness half way, and i do not get that black bar!
I had the same problem on the tab S3. Samsung text said it was a known issue, affecting about 30% of all screens. It is replaceable under warranty. Eventual getting through the first round of tech support, ask for support team to handle your issue. My tab S4 had the same issue, but it wasn't as noticeable. I accidentally folded into a fold-up couch and demolished it, whenever I got a replacement under AT&T insurance policy, the tablet I got had a perfect screen! I'm taking has best care of it as I possibly can, as it is literally the first perfect screen I've seen on the S Series tablets. It may be frustrating to deal with the 5 to 10 day turnaround time, but as an artist who actually works on Gray backgrounds quite often it was worth the effort.

Thank you for testing this on your tablet. Actually, the overall brightness was about 15-20%. But that was enough for a dark/dim room.

Oh, do you have any references for this?
Ouch. I can feel the pain of the couch event.
Well, my tablet came today from the tech support... They wiped the memory and cleaned some greasy fingerprint marks.
But they did not solve the problem. I guess they even tried to find out what was wrong.
I'm starting to be unhappy with Samsung...

No direct reference as it was a tech I was speaking with on the phone. Just ask specifically to be forwarded to support team. Then you will only be speaking with one service rep, and they will be in direct contact with the tech that handles your tablet. They can even ensure it goes to the repair center closest to you.
Well... I'm feeling like this story needs an end.
I actually send the tablet to the repair center and they changed the screen. The lady at the store were I purchased the tablet told me that the problem was a loose flex cable inside the tablet, but... Who really knows? The repair sheet doesn't mention that.
Anyway, the tablet is better now, but not 100%... It still shows a slight darkening towards a corner of the screen, barely noticeable under normal circumstances but that does indeed shows with test images. The good thing is that this is not a dark band anymore.
Thanks to everyone that participated in this thread
