[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

That's what I am thinking but before I contact Clove tomorrow it would be interesting to hear if this is an isolated case?

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.

[Q] Nexus 7 (2013) touch screen!?

Hello,
I'm a new to this so don't be mean.
My nexus 7.2 receives a grayish blueish smudge right down on the bottom middle of the screen probably on the 3rd quarter of the screen. Every time I apply medium pressure to anywhere the on bottom half of the screen the discoloration happens. Is this normal?
Thanks

No, that's not normal. Only thing I could think to try would be to try a kernel that allows you to change color and hue of the screen. If that doesn't help it sounds like you either might need to find a new screen and do a self repair or send it off for a fixing. Can't recall anybody else ever mentioning that. Unless somebody else has a better idea though, I think that's your only two options.

Does it look like a light bleed or something? I realize you're new and they might not let you post pictures and stuff, but it's hard to say without seeing what the screen does.

It looks like pressure is accumulating upward at the single point, creating a grayish hue. I guess to be an example, when you press hard on an LCD there will be a rainbow hue next to or on the pressure point. But mine is always at a single spot.

Yeah, I think you have a display/hardware issue on your hands. I was just playing Dungeon Hunters last night in landscape and was hitting both sides of my screen pretty intensively and saw no color changes. If it's bad enough, you'll probably need to send it in for repair or try the DIY route. Sorry, not much else I can think of to help with your issue

Okay thank you for the input. I just have one more question, since the pressure seems to accumulatting in one spot, will that crack my screen? Because the color part is minor and I do not mind that slight discoloration. All I really care about is the chance that will crack my screen.

I doubt it, not unless you dropped it or something where you think you may have caused a weakness in the glass itself. You gotta remember, on all these device there are multiple layers to the glass itself. I'm guessing there might be a small defect in yours between two of those layers. Do you remember it happening after you did something or did it one day just start happening. If it's the latter, then definitely a manufacturing defect. If it's bad enough, if it were me I'd do some research and see how much it'd be to replace the screen. Depends on how long you were planning on keeping the tablet.

I broke my Nexus's screen and digitizer two weeks ago, I got it replaced by a company and that is when I noticed that grayish hue. Should I go back and ask them about it, because I plan to keep my tablet for a while. Also, as I said before I don't mind the color, I just want to know will my screen crack eventually from the increased (I'm guessing) pressure accumulating in that one spot.

I would definitely go ask them. Being that it is a replacement screen I'd go get either their professional opinion or another. Ideally ask them about it and then get another opinion. In a normal situation I'd say no to your screen possibly cracking, but there's something obviously wrong with the screen. I would say it shouldn't but I'd take it back and get a second opinion just to be on the safe side if it's not too much money.

Thank you for your replies.

Replacement digitizers are of various grades. There are those that work but didn't pass QC because of minor defects. These sell at lower prices. It's true that the LCD surface is harder to crack than the digitizer. But it lies on top of another much thinner layer that would crack as readily as the digitizer given undue pressure while handling it. The people who replaced should definitely be held accountable whether it's their fault or the manufacturer's. Hold them to it since if it's a tiny crack now, it's bound to expand with time..

All good here with Lollipop AOSP !!!

I went in and asked them about it. They told me since I broke it and had it repaired, not everything is going to be 100% and that funny looking grayish thing from pressure is the result of them putting in a new screen.

Would that grayish thing really cause my screen to crack? What should I do?

Well then, aren't they saying it's their doing that's causing it? I am not a technician, but I've replaced quite a few. I did it for fun, and a chance at learning what it's made of. Nothing you experienced was supposed to happen with a functional combo (even a B grade unit) , put in place carefully. They're supposed to have the necessary skills. They charged you for it. It doesn't cut it when their reply is that they don't measure up to the job, unless I'm missing something here.
Depending on the tape they used, removing the screen would more likely than not break it. But it's their responsibility. They chose the vendor, and they installed it, and now it has a defect. I'd contact the BBB if they refuse to fix it for free. It's an issue of implied warranty.

Faint lightning bolt visible on screen at all times?

I've tried searching around but couldn't find anything. But theres a faint grey lightning bolt on every screen. I can even see it right now whilst typing. What does this mean and how do i fix it?

need more info.
where does it go from to?
horizontal, vertical or diagonal?
best of all a screenshot!
If straight line horizontal or vertical then more likely pixel problem with screen, could be hardware or software. If diagonal/zig zag etc maybe a cracked screen... hard to say without seeing it.
There's an app on play store to fix dead pixels etc that might help, never tried it myself though.

I actually have a slight case of burn-in on my phone, so I did some research on this. In short - our screen is AMOLED, and on it dead pixels don't manifest in the same way as e.g. an LCD. The screen simply degrades over time (never gets better), and parts of the screen that show the same thing over and over are to give out first.
There are apps that supposedly fix this, but I would't really recommend them. What they do is that they slowly wear out the whole screen, until the point all of it is equally worn out. Imagine this as if having a scratch on your table, so you decide to sandpaper the rest until it becomes invisible. Overkill, but I guess the only way if it really bothers you.
That's not to say this is a case of burn-in, the info given being so inconclusive. This would also imply that some form of "lightning bolt" stayed static on the screen for a very long time. Perhaps charging while the phone was shut down? Maybe a wallpaper or a daydream option? Who knows.

The last paragraph seems likely. I screenshot red and sent and the person didn't see it. But it's a faint lightning bolt right in the middle of the screen and is present no matter what I do.

Yeah, burn-in isn't visible in screenshots. I recommend that you download a flashlight app that lights the whole screen in white or some another color, and then carefully inspect exactly what you see. In the case of burn-in, this is going to be something easily recognizable such as a charging screen or the like.
Sadly, not much can be done here. You can always replace the screen as the most expensive option. You can download the AMOLED Fixer app and wear out the whole screen, but this is bound to reduce its life...
...or you can just, well, live with it. This is not really that big of an issue and simply happens over time, with minor annoyances for most users and more extreme for others.
Just for the info, where and when did you get the phone? Was it from a shop?

I bought the phone off a friend for super cheap as the charging port and battery were gone. I replaced them for cheap so I have a great S4, I noticed it whilst watching a movie. I don't think I'll be interested in replacing the screen. The cost becomes too much.

I can relate - bought it off also from a friend who seemed to spend a lot of time on Facebook and Whatsapp - so much, in fact, that the keyboard managed to burn-in along with the status bar. Doesn't really bother me, though, as it's barely visible most of the time. One can only blame Samsung for sticking with that technology for so long (I don't think any other manufacturers use it that much?). I would take a durable screen over a slightly better color quality any day.

Oneplus 5t - Screen uneven (feels like air is trapped underneath)

From the beginning I knew I loved the 5t - the curvature was simply perfect and I was really impressed by the stock standards that OOS implemented. Face unlock was unreal (as everyone knows), and the photos were decent enough that I didn't regret not buying a Pixel 2 XL. I mean, I saved a lot of money going the oneplus route (1st time, might I add).
But there was always one major issue - the screen sometimes felt uneven, like it had ripples in the display. I chalked this up to my imagination being wild and kept using the phone. But each and every day now I can't help but notice that my screen doesn't feel perfectly flat. My friends are split 50/50, some think that there is unevenness while others have told me I'm out of my mind.
So with all that in mind, please help me understand what I need to do to fix this problem, and does oneplus customer support suck as bad as everyone says they do?
1. Ripples under the screen or air bubbles - is this even possible? can a glass screen morph around bubbles (change it's shape) without cracking? The screen is perfect with no scratches.
2. Has anyone else felt the ripples or unevenness on their screens?
3. I put in a trouble ticket with oneplus - are they going to laugh at me because of the unlikely nature of this defect?
4. If I send it in, I'm concerned their technicians will do very little testing and just return the phone. It is literally in the same state as the day I bought it. Are the oneplus horror stories true, or overblown? Would they really return a defective phone? Google, when I had my nexus, would replace the phone even if they found out I cracked it with a sledgehammer. I don't expect the same from a smaller company, but I do expect a level of understanding to MY PERSONAL EXPERIENCE with the phone. If they have no empathy, then they're definitely not going to be of any help to me.
Sorry for the rant/long post. I hope to hear from xda users because I know you guys care about the details when it comes to hardware or software.
Thank you.

If you feel like something is wrong, DO NOT hesitate opening a ticket. Their customer service probably seen worse than that.
I don't have any of the issues you're experiencing, but I guess it could happen.

... you're not talking about the pre-applied screen protector, are you?

If you look at the screen at an angle you should see if there are uneven spots on the screen.

Why complain instead of get a replacement phone.
It's not like everyone else has the same issue.
Just make sure you don't have a screen protector on first, as that could be part of the problem.

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.

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
