Possible screen issue? Or not... - Samsung Epic 4G Touch

So I bought the phone a few days ago and love it (coming from tmo's vibrant). Yesterday however I started noticing something with the screen that I'm not sure if it applies to all of them in one way or another. When you pull the notification curtain down there appears to be a few discolored (darker) vertical lines that are noticeable where it should be solid gray. Depending on the brightness there more visible and vice-versa. I found a thread on the European version of someone reporting the same thing. The lines are definitely more visible with dimmed screen in low light conditions.
Anyone notice a similar deal?

I have the same issue every now and then. Especially when i open the market, not really a nuisance though.

Yeah I noticed it there and on the xda app as well. Just wondering if that's a defect or not, if so I might exchange it. I could still run in to the same issue though..

Screen defects?

After a few hours of playing with the VZW Nexus, I noticed a thin, vertical line of pixels that are lighter than the surrounding area. It's really noticeable on white to gray screens.
Has anyone else noticed such a defect on their display? Would VZW exchange it? I probably won't be able to get to a VZW store until the weekend is up, and I'm worried that they will assume the delay means that I caused the issue.

I think that's just an artifact of amoled screens in general. AFAIK, SGS2 had the same issue.

Are you sure? What I have looks more like stuck pixels; a line of pixels that are firing at a consistently higher brightness than the others. I had a Droid Charge before this phone and never had this issue.

The Charge doesn't have the same screen, it was SAMOLED+, the Galaxy Nexus is just SAMOLED.
That said, I'd need a better idea of what you mean, or how you're testing it. But I don't think I see it, and I'm pretty picky about my display.
I am a little disappointed in the odd washed-out look it has, almost like the gamma's too high.
Anyway, Verizon would probably exchange it, but you'd probably need to call in and have them ship you one. Going in-store you'll be fighting with stubborn sales reps who aren't getting a single dime of commission off their time with you.
My first unit had that, my current one doesn't. Try for an exchange, mine is perfect, but took two tries.

Is there a way of fixing it, like how you used to be able to fix old tv's with a magnet?
i have the same issue... and i can`t make an exchange because i bought at USA and know i`m in BRAZIL. =/ have some way to correct this problem??
thanks
Judging by the crickets chirping, looks like the only thing you can do is exchange it.
Has anyone had any luck with replacements? I get the vertical/horizontal line issue at lower brightness, but even at higher brightness solid colors look somewhat grainy.
I had a vertical line and some random spots with pixel problems. It wasn't visible during the day, but at night those pixel were darker than all the rest. Got a new phone within a couple of minutes in the store.

To exchange or not exchange, that is the question...

So I purchased the CDMA Galaxy Nexus last week and love it. I'm coming from a Nexus S and while I think the S had a better screen I think the Galaxy's is great nonetheless.
Either way before I purchased it I lurked these threads and saw that a few of you were having screen related issues. So upon buying the phone, I promptly installed a few screen tester apps to check mine.
I found mine to have quite a few imperfections while displaying an all black screen. Blotches and lines to be exact. And so I asked Amazon for a replacement.
The replacement ended up having fewer imperfections than my original one but they were still there. And not only that but it seemed that the colors were more faded on the replacement one too. So now I have the two phones here and don't know what to so.
Should I keep my original one and stop obsessing, should I send the original one back or should I just say screw it and send both back in hopes for a better third unit?

No opinions/suggestions/advice...? Anything? ANYONE??
Exchange, not exchange...get an iPhone, maybe?

The franco.kernel app has handy color control options, imo thats about the best thing its good for, it eats the hell out of battery and I get random reboots once a day since flashing it.
The nexus s has better screen than the galaxy nexus super AMOLED HD lol u clearly don't know what ur on about the blotches and stuff is normal on a amoled screen if it is displaying black
If it isn't noticeable under normal use, just stop obsessing about it. I've noticed on a flat black or dark grey screen there are a couple bands (nothing major) but I can't ever notice them in normal use. Its just not worth my time.

Totally agree. AMOLED has issues in terms of a few production defects, but nothing major.
If it bothers you in daily use, exchange. If it is only noticeable when you look for it, stop looking
Thanks for the replies guys
Yes, IMO my Nexus S's screen has more vibrant colors than the Galaxy's. But that's not to say that I don't think it's gorgeous still. It may be due to Voodoo colors or who knows. I use the tweaks in Franco's app by the way, and that has made it much better.
My main concern over the blotches is that it could be an indicator of a possible early screen failure. Probably not however, I'll stop obsessing.

Like the other person said, it is normal to see blotches on a full black screens when in a dark room. Some spots are darker on the screen and sometimes you will see lines. Not a big deal to me.
There are some kernels that allow you to change the colors which will give you a great improvement. Like someone mentioned Franco's kernel and also lean kernel.
If you install AOKP and lean kernel you can control the colors right in the settings menu. For Franco's kernel you might have to by his app for that. Not sure you you can change the color's within the Rom.
I also believe CM9 might have color settings built into the Rom with the stock kernel...
If you mean some lines and pixelerror like thingys on black dark screen than I can tell you:
I'm with my 3th GNex now and all had this "errors" but I can't see them on daily usage; just when for example I'm in a completely dark room and brightness is on 0% and then it's kinda hard to see it too...

Should I worry about screen burn in?

I'm considering getting the S3 but Im worried about screen burn in. I'm the type of user who uses the lowest brightness possible. Should I worry?
I don't think burn ins are a concern with these screens. I left my screen on on a few separate occasions displaying a single image for over 7 hours each time with no problems so far.

I wouldn't worry. You need a still image to be up for an extrenuous amount of time. It is possible though, but you'd almost have to try. I haven't seen any posts with users with screen burn either.

Does using the lowest brightness possible reduce the chances of this happening or it doesn't matter?

Use auto brightness.. and set the screen to turn off when your not looking at it.. my S2's screen was messed up but so far with this phone nothing

Yeah, you never see much complaints about it but it's definitely possible. I'm going to guess it's less possible than previous version of the AMOLED displays. On my samsung infuse after 2 years of using the AOSP android keyboard, I could somewhat see an imprint of the keyboards keys whenever a dark-grey image is displayed on the whole screen but it was extremely minor.
You will get some burn-in with AMOLED after a few years no matter what. Pentile AMOLED (in the S1 and S3) is also superior to the AMOLED+ in the S2 for longevity, or so says Samsung.
My 2-year old Captivate has some up top where the notification bar is, and on the bottom where the keyboard is, and where the high-contrast black&white WordFeud game tiles are that I always play.
The burn-in ghosting isn't THAT noticeable, though, unless you're viewing mostly white images or webpages.
S3 do have burn ins just to let you know. Download screen filter and lower the filter to 10% or maybe 0% and you will see imprints. or download dead pixel test and the second color will show also all your burn in.

Also be in a dark room. Since in daylight you won't see the result.

Thin green line at the top of the screen

Anyone experiencing thin line at the top of the screen it appears green at black background and as a brighter colour on different backgrounds
I'm wondering is it software issue or rather hardware one

That just started happening to me too...I think I've just gotten used to it - though it's still annoying. I haven't looked into/researched a fix yet.

Can you post a picture? This seems very odd, I'm not sure if it's dead pixels or some other kind of glitch.

Is brightness control (or whatever it's called in the rom you're using) enabled perhaps?
It seems to come and go, worse at certain times. Right now I can barely see it, but I will post a screenshot as soon as it comes back.
Sent from my Galaxy Nexus using xda app-developers app
If it's hardware issue the screenshot won't show the line at all but if you can truly capture that line in a screenshot chances are it's a software fault.
Same here the line doesn't show up in screen shot
Could anyone who's experiencing the issue could post which Rom and kernel you been using?
I'm using modaco prebake and Franco kernel

You're right nothing showed up with the screen shot when it came back last night. I'm running the latest Bugless Beast 4.1 with the new radios.

I've checked new Ron same issue
If you will go to landscape mode and watch a video probably you'll realize as me that the line is at the top and bottom of the screen. The u can notice that when you press navigation keys as well

Are you on a custom ROM and are you sure its not the battery option selected that shows a green line across the top of the screen? It changes depending on your battery percent.
I haven't really played around with better battery stats because I get pretty good charges out of the battery, but played a video earlier in landscape and the green line stayed in the same place - thinking hardware issue.

Running stock Jelly been just noticed this today, have had the phone since June I think. Phone is always in its leather case/wallet with a screen protector so no phone damage.
And it has the same issue, green line or bright colors base on the background. just one line about as thick as the pull down notification bar. It got a bit better during the day, green line in portrait disappeared, now I just notice it when horizontal. but this is the first day.
Anyone send theirs in yet for repair?
I also noticed that on my GNex as well. Big probability that it's a hardware issue, like a line of dead pixels. Doesn't bother me much though, as it's so thin I sometimes don't notice it's there. But when my OC mode gets activated, it does seem distracting @[email protected]
Why not call Samsung for warranty repair? If you are under warranty, they'll let you know to send it in.
I called (888)987-4357 for my repair and they were actually really helpful. They're located in Texas FYI
Hi!
I had the same line. It can be clearly seen when the camera is turned on, or other apps in full screen mode. Line can be green, or red, or white.
Line appears for the first time when it was low temperature outside (-20 С, i think...), two weeks ago. I took the phone out of my pocket to read message, and saw the green line at top of display.
Now, if the phone placed in a warm room, the line becomes a barely visible. In a cool place it becomes clear visible.
Today I went to the service. They reinstalled the firmware, but the line is still on the display. They said that it is hard to see this line, and maybe they must to ask Samsung about this line. They are not sure that this line is a malfunction. At the same time, they are ready to replace the display (after arriving from Samsung's stock). Not clear for me...
I'll go to the service again in a week, and will report about result.
Good luck and sorry for my English.

I have the same issue. The Green Line on top appears when it's cold outside and normally its just brighter line which you can see only in landscape mode.
I think the only thing you can do is replace the screen
Going tomorrow to service and will let you know after

Hi!
I went to the service again. After four days my phone returned with a new display. The line has disappeared, everything is fine! :thumbup:
P.S. This repair was under warranty.

I have a strange line on the top but i never saw it green. It looks like a line of pixels with different brightness.
update1: just sent my GN to customer service
update2: came back with a new full working screen
I have only noticed this when i viewed the video file on the computer using VLC. When i took a shapshot of the video, and then enlarged the picture to fit on desktop i could see the green line. It is only one pixel in width, not noticeable otherwise.
Is this really a hardware issue if it is happening to every GN phone in the same location ? I think it is software based. perhaps to make up the right pixel dimension ??

Definitely a vlc software error.! Isn't vlc on android platform still beta?
Try another player and look if you get the same result. There are enough you can choose. MX player for example is a famous one.

[Q] Screen bleeding - anyone else?

When I run this app, and adjust it (using volume buttons) to run at 100% brightness, I get screen bleeding on the left and top right sides of the screen:
https://play.google.com/store/apps/details?id=com.joeleveque.backlightbleedtest&hl=en
http://i.imgur.com/fvf5Hos.jpg
The picture doesn't really do it justice, it's quite distracting when looking at dark images.
I was thinking of taking it back and swapping it for a new one. Before I do I wanted to make sure this isn't a problem with all units. Can anyone else replicate (or not) this issue after running the linked app?
You should return it.
I installed the app on my nexus 7.2 and the color was even through out.
I've got bleeds on the upper left, but I didn't return mine. Apart from light bleed, which is prominent and ugly in dark, nothing's wrong. So I've retained mine.
Fair enough, I'm wondering if it's worth bothering returning it now.
I have what I consider minor light bleed. I only see it on the bootscreen. I opted to keep it because the next one could be worse.

I should also add that I'm extremely picky

Have not seen any on mine. Admittedly, it would probably have to be significant before it bothered me, so I may have a minor amount and it just isn't noticeable. Also, I don't want to go looking for problems that don't affect me. I'd drive myself nuts!
I noticed today that my nexus had some light bleed. Should it be exchanged? I have no multi touch problems/random reboots/ghost touches/GPS issues or any of the other mentioned problems.
