On a Verizon gs4 I've had issues with black's being displayed since doing a screen replacement. The darkest areas of the screen appear more pixelated or appear to tear at the edges. I've used another screen to test but with the same results. I've also changed ROMs, several times, with a full wipe in between with no changes. Im wondering if this maybe a problem with the connector or the mobo itself. However, is there a way to check the display pin connector for correct volts and what would those be? Any assistance or tips would be awesome! Thanks

That photo is correct. The grey pixels are shading. At least from what I know

Perhaps that wasn't the best example image. I've attached a few screens you'll notice the dark areas almost losing resolution. Doesn't happen on same video source on diff device... stumped

Hello XDA,
I've searched around for this problem a bit, and it seems this issue hasn't been brought up anywhere. If it has, then I apologize.
The S2 has an awesome display with great colors, blacks included, but I noticed this issue one night when I was watching a film on my S2. When the display is showing black/dark images you can clearly see what appears to be glue smudges all over the screen, especially along the rims. It is only noticeable when there's little to no other light in the surrounding environement. Increasing brightness seem to worsen the problem.
It is hard to describe and very difficult to capture on camera but I made an attempt. I can't post links yet it seems but here's an imageshack url:

The image was taken with a Canon 450D with 20 sec exposure (hard to focus when it's that dark I'll tell you). Edited slightly in photoshop to cut down the size.
Here you can see the general color of the screen (gray-ish) and some of the blotches of (what I'm guessing is) glue in the back. If I had to guess I suspect the blotches might come from the capacitive touch layer of the screen. Is this an issue or is it to be expected on phones like these? It's not a major problem but it's actually quite annoying when you're watching a film/youtube clip/playing a generally dark game or whatever. Should I return my device? I've used it for just about a week and a half.
Thanks in advance for any help.
i have this too, its the AMOLED display. you can turn the screen off and on and you'll see it go off n on. not the sgs, but amoleds generally. my omnia HD had this too (1st gen AMOLED)
the blacks are not 100% black i say
Im having this too, nothing to worry about this as it doesnt disturb the beautiful display of this mobile.
So I've been looking closely at my screen lately wondering if it might be defective. Gradients seem to look bad on all SGS phones, but the gradients on my phone seem to look extra bad. They don't just look banded, they look similar to JPEG artifacting as well.
Not only that, but in certain games there's almost a visible "film" over the screen, but under the glass. The best way I can describe it is an unchanging group of lines or artifacts on top of the actual screen itself. This is quite noticeable in person, but is probably going to be hard to see in the video I post due to the fact that I'm recording a screen. My suggestion is to take a look at the bottom left-hand corner. It's most noticeable there.
The image I posted I just noticed today. On the Netflix login screen, the red beside the email and password boxes is a lot brighter than the rest of the red. This is significantly more noticeable at low brightness, but still noticeable at regular brightness where I took the picture.
Is this normal or do I have something wrong with my screen?
Thanks!
EDIT: I took another video and another picture where everything is far more apparent.

OK, I have seen several threads here, concerning image retention problem, sometimes marked as screen burn. So I thought we could collapse into one general thread on this subject.
So, LCD screen does not have image burn problems. Image burn is name for persistent effect. What we have with our Primes is image retention. This effect is caused becouse liquid crystals in LCD gets used to its certain possition...
For example, if you have some bright background, and you leave it unchanged for about 10-15 minutes, than run some grey screen picture, you will see "ghost" of the background image in the app.
This effect can be seen in many screen technologies. S-IPS and AMOLED are widely used ones on tablets and mobile devices. They both suffer from this effect.
There is actualy big chance you won´t even notice that. Prime turns it screen off after some time, and when you use your device you are probably actually doing something, meaning you are dynamically changing the screen, so image retention has no time to take place.
In everyday use, problems could occur when you use SW keyboard for a long time, or for example game menu controls, etc.
The most important thing is, this is NOT PERSISTENT. Image retention of this type should dissapear after while, you can speed it up by either turning screen off or displaying plain white image for a while.
I believe none of our tablet displays are immune to this. In fact, even glory iPad 1&2 displays are not immune. Neither was my HTC Diamond screen. (Yes, pretty old, but it has nice VGA screen). Sometimes I get navigation cursors retained after reset, even for few minutes (on my HTC Diamond)... So I believe we just need to live with this effect. Most of the time, you won´t even notice it.
But we can share our experience. I have not notice any image retention untill today, when I needed to discharge my Prime more quickly, so I maxed brighteness (IPS+ on) and leave it in home screen on for about 15 minutes. Than I started YouTube app, and on its grey load screen, I clearly seen ghost of my homescreen background. I immediatelly retried lauchning YouTube app, but it was all gone. If curious, or if you want to replicate this, my homescreen image is the default with tree, most yellow-ish like I believe autumn sunset version

Think that is the root of your ghosting issue there, would not call that normal operation at all to leave it maxed out for 15mins. The display is super bright and I dont think even outdoors you need max IPS+ to adequately use the tab.
Well, if I am right, it sould have nothing to do with brighteness level. Like I said, it is different effect, it is not burned. But maye thrucomming light intensity has some effect on the crystal polarisation...
Thanks for the post, I get this effect with my Nexus One as well. The notification bar from having the phone in portrait mode shows itself at times in landscape.

Actually LCD panels can get screen burn, I have had two LCD HDTV s that had it. But those were first gen LCD HDTV s.
You shouldn't see anything like it on LCD screens of today. If what your saying is true then why isn't the status bar in ICS (or honeycomb) ghosting for everyone?
I've done some tests recently after finding this issue on my Galaxy Tab 7.0 Plus. It was VERY dramatic on that tab. Only a few seconds on one screen, change to a screen that is mostly gray and the image persistence was there for quite a while. And it was a strong persistence. Not just a faint image. You could easily read text and see images. The pictures in the following thread show it.

But after having this issue, I ended up testing some other tabs I have. I've seen the issue on my Kindle Fire's (I have 3 of them). I have a Lenovo Thinkpad Tablet and have not seen the issue there. I also have a Transformer Prime and I do see it faintly on the prime, generally on the right side of the tab when holding in landscape (with power button on top). I also see it sometimes on my 30" Dell IPS monitor.
I guess the point is, it is more common than you think. But some screens may exhibit the problem more than others. That Galaxy Tab 7.0 Plus (that specific one) exhibited it far worse than anything else I've seen.
I've decided not to worry about it. If it's happening to yours and it happens very quickly and doesn't go away quickly, perhaps your display is worse than the norm. But I would expect all of these displays to show some level of image persistence. Return it if it bugs you, but accept the fact that they all may have this issue to some degree.
Thanks to the OP for this post.
I got my hands on a Razr x910 and it has screen burn. what are my solutions for this? Can i order a screen from someplace on the web ? what are my options?
please post a picture, i ve never seen a problem like this in a so short amount of time
Do you mean like black dots when the the screen is black?
I thought only plasma screens have burn marks
There are a couple apps that can attempt to reverse it, like Display Tester, fixes the burn by scrubbing the pixels with white and black nars, try it, couldnt hurt

here is a picture of the burnt screen. its a yellowish tinge in the screen. whenever there is a white or light screen you can usually see them. However it doesnt effect games/videos, so its not to bad..
I ran that display tester and no luck!
I'm not even absolutely certain that's screen burn. AMOLED is kind of notorious for... inconsistent... colors (especially whites). And the RAZR in particular has some artifacts that are especially visible in the dark. They don't impair usage generally. But then the display I'm on typing at the moment isn't the best so it's hard for me to be sure how bad it is on your screen.
EDIT: scratch that, looked closer and I can make out the launcher icons at the bottom. That kind of sucks, actually.
its not to bad, and again only on light screens. I am always going to run a dark background so its unnoticeable. But when i run into some extra money ill just buy a new screen This place http://www.repairsuniverse.com/motorola-razr-lcd-screen-replacement.html
seems legit for a not bad price.
Might want to turn down your screen-on time as well. The only other RAZR I've seen like that was the demo unit at the Verizon store & its screen is on all the time.

Whiskey Tango Foxtrot... I've never heard of this on a mobile device, a tablet, or a laptop. Although cheaper LCD TVs (like my POS Westinghouse) can have it happen. An impractical solution would simply be to leave it off for a few days. But, that's not going to happen with a phone. If you can find a video of static... like a TV screen on a channel with no signal... and can have it run in a repeating loop, leave it plugged in and run it over night. The random white/black pixels will clear out LCD burn in. It might take a few sessions.
There's an app called JScreenFix that can be used to exercise the display as well. This issue was a problem on the first generation Fascinates. The samoled screens would retain the image of the status bar clock or the whole status bar.
Technically, it's not burn-in I guess, it's more like pixel degradation in certain color spectrums.

hello all,
i have an LG G2 and I noticed there are weird horizontal lines showing on my screen as shown in the picture (lines showing across the picture with pants)
does anyone know what this problem is?
Can't recognize any lines, but if you think that there is a problem you should make use of your warranty and get that thing fixed. Can you see the lines in all circumstances, like e.g. playing games, white background, black background etc. ?
Cant see anything... Maybe its a problem of liquid spill lr something... Better to get it fixed with service centers
Does it show up all the time in all the apps?
Its because of the amoled display, 99% of amoled displays have either these kinds of lines, or little black stains, and can be seen with black backround, the lowest brightness, and under a certain angle dont worry

G2 has a LCD. (http://www.gsmarena.com/lg_g2-5543.php)
@op Get it checked at the service center. I would also have a look at another G2 just to make sure.

Display question...
From the tiny picture, it appears to be an issue with the poster of that pic, and not your device, unless those lines are moving with sceeen scrolling and can be seen in other images.
Aside from this, it might just be 'that' image, and not a true problem.
Take a pic with your phone's camera and view that image, if you see lines on your image, then you probably have a defective screen, as the capacitive touch screen overlay does not cause these issues on their own, they have no direct connection to the screens, they are overlaid onto the screen, and not a physical part of it.
I see the lines. There's one in the first thumbnail and several in the fourth one.
I have the exact same issue on my phone after having a broken screen replaced. Did you ever solve the issue?
