Screen streaking/unevenness?

I haven't seen this mentioned anywhere else. Does your ET show (mostly) vertical streaking/unevenness when displaying a solid, light color? Is this something related to AMOLED, or is my ET defective?
Edit: I just realized this is dependent on screen brightness...the streaks are only apparent at the lowest brightnesses.
Thanks.

Screenshots would help others see what you're referring to.

I get this when my screen goes off and on

I have to mention that the first one i had, was like this, but it showed like a dark spot in the center of the screen, btw screenshots wouldn't show this problem because is actually the hardware" Screen" In this case.
So i went ahead and brought it to the Sprint Store where i bought it from, and asked for a replacement due to the Screen hardware defect, they kept *****ing at me telling me, that they have to keep it for a whole day, to do "Tests" Im like... well its a hardware issue and i have taken the phone and hardreset it, making the phone as if just out of the box, and showed them the problem again"btw the phone comes with a Gray and Green pure colored background images that you can show to them, that it isn't an Image that you had Altered" , and they can see that it is the screen, and its what i showed to them, and thats when i got my replacement, When i got this one, i saw it again, and it had a white spot... also had various streaks coming from the Top of the screen, went int he second day and got me another replacement, but before i left the store, i stayed about 30 minutes in there, testing the phone out, and downloading all the apps that i had in the phone before. Also Good way to notice this problems( defects ) is dimming the screen all the way, and changing the background to gray, which is a default wallpaper.
This screen didn't have any of the defects that previous ones had, so im a happy camper .
So now what i'd recomend if you can, is replacing/exchanging the phone until you get one with a decent screen.

I get this too when my brightness is turned down. It's most visible on grays. Like the background of the market. It only appears when the brightness is turned down low. There is also this app in the market called "screen test" which cycles through different solid and colored backgrounds. that if you did take it in you could show them that. This issue doesnt really bother me but I have TEP plus there is a one year manufactures warranty so if it gets worse I'm not worried about it.

I finally got around to taking a quick set of comparison pictures. Sorry for the poor quality, I took them quickly with my phone. I also tried to purposely take them out of focus, so moire patterns from the actual pixel grid wouldn't confuse things. I have a feeling this is how all *LED based displays are.
I use the app "Colors" to quickly get a solid patch of color. I encourage a few people to download it, and browse through a few colors (grayish or dark tones - light or bright colors aren't affected as much) and see if they have it. "Grr-ey", "Mighty Slate", "Kind Giant" are good ones to test with.
Things are much more noticeable when the brightness is set low.

Not sure what you're talking about. Do you mean the 3 dots on the bottom? Those are the 3 bottons which correspond to the back, home, and multitasking buttons. Pretty sure its a bug that they're showing on the lockscreen. And pixels are a lot smaller than those dots
And if pixels are physically broken/malfunctioning on your device, we can't see it in a screenshot

Sorry didn't notice the screen shot turned out bad but no not talking about the home button etc. The top right portion and all the black above the home back and app button is what I actually see. The background will be there dim and then just random black chunks and squares appear such as they show in the screen shot
Rolled out from my Gnex Prime

PS obviously it does show up on the screen shot as its right there and yes I know pixels are smaller however there is a pixel like pattern as every blacked out area of the screen is in those pixel like squares
Rolled out from my Gnex Prime

Here's a new one. Again notice the black blotches on the bottom left and center top. I noticed this in the clock app when I dim it. I've also noticed a blacked out streak in the gray background when I load up gta3
Rolled out from my Gnex Prime

That looks like the background picture used. It's probably of low detail.

The background is the standard galaxy nexus wallpaper the same one found on half nexus reviews and I'm pretty sure the nexus reveal as well. Normally the background looks nothing like that and even when I dim the screen in the clock app it never looks like that until the screen shot. The main point I'm making are the black blotches in the top and bottom that appear on many apps randomly
Rolled out from my Gnex Prime

here's more black blotches hard to notice on the screen shot though
Rolled out from my Gnex Prime

Okay, bro.. my advice would be to exchange it. It doesn't matter if anyone here notices it, really. If it's bothering you, that's all that matters.

.... wait is this a joke? Like I said. If you're having trouble with your screen, the defects will not show up in a screenshot. You have to take a picture of the screen with another camera lol.
Obviously something is bugging you on the screen. Return/exchange the phone if it bothers you that much.

I'm just curious if anyone else were to go to the same things if their phone does it as well. If its on most phones I'm not going to worry about it but if its just mine then yeah I switch it out. I'd just rather not switch it out for a new one that has the same issue as well as all the other ones people have been complaining about on theirs as mines been pretty good

Thats fine. But no one knows what you're talking about if you keep posting screenshots. We cannot see the problem with a screenshot...

(Erased frustration)
Rolled out from my Gnex Prime

I apologize for the rant. I just checked using my computer and the blotches don't show.... :/ I'm confused lol my phone even shows the blotches in the screen shots when they are tiled in the gallery however I can zoom in and move the picture around and the blotches remain. But each picture has dif blotches and they each remain on the screen for that specific picture dispite zooming and moving. Sorry idk how to describe it really
Rolled out from my Gnex Prime

I guess for example on the gta3 shot with orange letters the blotch is a line from the left screen going to the center. I can zoom in completely away from that original spots and the blotch remains in the same spot on my phone. Swipe to the side for my next screenshot and the blotch is in the new location and remains despite zooming and moving. That a little better? :/ again sorry for snapping its late I'm crabby and don't like noticing faults in my phone ha
Rolled out from my Gnex Prime

You need to either take a picture of the screen with another camera or no one can help you because we don't know what specifically you're describing.
It is clearly frustrating you strongly. You should exchange it.
There are several other threads on screen defects, maybe you should browse through those.

How's this? The bottom if the phone when in camera app and dimmed
Rolled out from my Gnex Prime

I recall reading that the thing with amoled screens is that they are able to completely turn off to display black. After flipping through wallpapers and apps I've noticed it only happens on dark ones. Perhaps the phone is being told that its a pure black space and to shut off the pixels there?

[Q] Would this qualify as defective?

My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.

unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that

All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.

White spot or white pixel on white, what is it exactly?

Im quit perplexed about this so if someone with experience can explain

i posted this a lot before but i want to know, there is some grain visible in bright angles, and actually i have two of those white spots visible at angles, one of them is pixel size the other as you can see in the pic is quit few pixels size
but it doesn't show on black, very minimal on blue, shows on every other bright color
whats is itexactly, a dead pixel would be black and appear on white, a stuck pixel would be white and appear on black, dust would appear under sun light or flash light when the phone is turned off
but its not any of those, is this imperfection to the screen glue or dust in the glue or back light bleed?
The grain i assume is just glue imperfection but this white dot is driving me crazy it's mid screen and ruins the nice view angles of the One X, the screen is fit well actually
I tried pixel fixers but no luck, right now i'm trying to leave JScreenFix running for two hours

I have one of these, I think it's just a hot pixel. I emailed Clove and after seeing a photo of it, they said HTC won't replace for one bad pixel. Same thing as yours, only visible on white screens at odd angles, can't see it when looking at the phone straight on, and can't see it all on anything other than bright colours. Wish it wasn't there, but it's not a big deal to me, the rest of my phone is fine. Let me know if a pixel fixer works for you, haven't had luck so far. But I haven't noticed it lately.

a typical hot pixel should appear on all the time even dark background, anyway no luck with JScreen except that the device crossed 55degree lol

Got the same issue. Send it for repair today, it bugs the hell out of me. If they wont replace my screen for i'm gonna ask a refund.

I just noticed that I have one as well. Not sure what to make of it really, could be a lot worse but its pretty peculiar. Anyone managed to shed some light as to what it is or been able to remove it? Or if HTC will repair it?

I have one in the middle of my transformer prime, irritating but prob the least annoying type of screen deffect. Only noticeable on white backgrounds

white spots while charging in off mode
I m facing some strange issue in my canvad hd...i seen some white dots on screen during charging in off mode..when cell is not on...the charging image shows..in just above i seen white dots...i thought it dead pixel...but when i on my cell ..this dots gone...no dots there...only in off mode charging...they shows..what is this..ny idea...
Or nyone facing this issue ?

Question Black bar issue

Hey guys, I've had the phone for about 3 weeks now. I started noticing it about a week ago. When I'm watching a youtube video at night for example or in dark environment on minumum brightness and pull the video down from the middle (when it shrinks the video itself and the screen gets gray on the edges) but don't close it, I can see a dark line where the status bar is. Seems that the youtube gray is perfect for the retention(?) to be seen. Does anyone else have the same problem or is it just me and should I ask for a repair or replacement? Sorry for the pictures, I took them with my old phone.
P.S. In case my explanation wasn't clear, when the yt video is on full screen, grab it and pull down and hold and you should see gray space around the video.
P.S.2. At first I thought it is a screen burn but after some research it appears that this issue is common on OP 8 Pro and is not image retention.
So is my phone faulty, should I book a repair or it's normal? Does anyone else have the problem? Tried changing to 60 fps but the bar is still there (

As the panel is made by Samsung, this is normal and it even appears even on the galaxy line flagships. It's a known tradeoff with having a hole punch and stems from the manufacturing limitation with their process.

Oh, I see. I've read that with the 9 series the problem is less persistent than the 8. Do you have the problem too? What's the chance that if I send the phone to repair the new display won't have it?

well that looks like the shadow that you can turn on and off in nova launcher, called "show shadow" but I'm not sure if you are using that.

Nope, I'm not. Also it doesn't make sense for it to display over other apps if it's the shadow. Anyways, I'm going to send the phone for repair.

I too have a faint row coming off the camera, it's alot less noticable compared to my 8 pro. There isn't any real way to deal with it as I read that someone RMA'd and had it replaced three times, all still had that "bar."

Is that woth the 9 Pro or 8 Pro, cuz I saw only one user of the 9 Pro complain about that bar. The problem is that I really don't want to wait a couple of weeks to get the phone back and don't want to risk the phone not being waterproof or arriving with any other issues. But you know that once you notice something, you can't just igonre it.

Was with the 8 pro supposedly, but still applicable to the 9 pro as it's a manufacturing limitation with all Samsung's OLED panels with hole punches. Some will be less noticable. OLED panels are not pressed and rolled like you see with LCDs. They are fabricated in ultra clean vacuum sealed environments similar to making computer chips employing lithographic techniques and methods in various stage of production.. as such they are subjected to the "Silicon" lottery and the quality varies widely between panels.
