Off-Color Screen Streaking?

I haven't come across anyone else talking about this... lately, I've been noticing that the screen on my Epic seems to have some sort of issue displaying grays/tans/off-whites, and I can see darkish streaks on any image that has those sort of colors.
A perfect example of this is the Tweetdeck app's gray background. I have already traded in for a new Epic from Best Buy because the screen had really obvious darkening that shouldn't be there on the left side of the screen when I used that app, and I thought it was just a bum phone.
But with this new one, I've recently noticed the same sort of streaking (no big spots like before though, just thin lines).
What's really strange is that it almost looks like it is something UNDER the screen, not an issue with the SAMOLED screen, but it only happens on those colors, so maybe it is.
I'm still going through the process of deciding if this is enough to bring it back again (it obviously doesn't hurt functionality), but has anyone else experienced this?

If you're displaying a non-constant grayish background, positioning of the pixels in the PenTile matrix can produce unexpected patterns and even colors (the N1 could hbe coaxed into displaying a rainbow with just using white and black pixels strategically arranged.) On a steady background though, it shouldn't be a problem.

So this is just the nature of the device's screen matrix? Would the PenTile matrix's "unexpected pattern" be unique to each device? Cause it always looks the same when it comes through, as it was with the massive darkening on my old Epic.
I have to say I can sort of see it even on solid gray screens (via the Dead Pixel Detect app), but it definitely is one of those "I'm really looking for it" sort of situations. I'm not looking at solid gray screens with NOTHING on it all that often.

I thought I was the only one. My second phone had it bad so I traded it in for a new one. This one seems to have it as well but not as bad. I notice it most on greys like when I pull the notification trey down. It is most apparent on the lowest brightness setting and solid colors.

I too am having this issue, and like you all, it only shows up on grayish backgrounds or the like. Is there any remedy for it? It's only a minor annoyance...

Perhaps one of you who is experiencing this can take a macro close-up and post it? You should have no irregularities on plain gray backgrounds.

The only camera I have at the moment is the Epic, but I'll see what I can do tomorrow.
It looks like I may be returning this one regardless... the screen on the left side is starting to lift out of the plastic bezel.

I'm also having this issue with my screen. It's pretty annoying. Does anyone know if there a fix for this or is it a pure hardware issue?

Screen marks only noticeable on low brightness dark screen

I have a relatively new (1w) sgs3 and have notice that in the dark room when screen has a darkish grey too off-black background solid colour (even on the stock notification background) and with tge brightness on lowest setting,then there many blob marks in the screen.
I ran a pixel checker which is fine but this appears like a defect in the glass itself. I'm not using a screen protector yet.
Can anyone else notice these blobs, some of which are as big as 3-4mm diameters?

Its completely normal on Super Amoled screens. I have them but it doesn't bother me since it only occurs on black screens. FYI, there was already a lot of topics about this already...

Haven't seen it on the SIII, but on the SII I have, this would happen with screen filter on lower brightness. I think that it has something to do with the level at which the pixels fire optimally. If they are under fed, essentially, the inherent flaws in the screen matrix (as in any manufactured item) become visible where they otherwise wouldn't.

I know this has been beaten to death, but it varies from phone to phone. My i9300 had a lot of blobs. My second one only really has one noticeable one. My i747 is almost perfect. It has little dots, but they are spread out and pretty much near the border of the screen. I wish it would have been the other way around...

please search before posting this topic has been discussed in great detail in another thread.

common on super amoled hd panels.

Same issue too. Checked with Samsung and they said it's common for the screen. Only occurs in black pictures low back light and dark room and it doesn't bother me

Nexus Screen quality at high brightness

Hi,
So I opened my nexus 4 today. From what I had seen on YouTube and read was that the screen was superior to galaxy nexus. It is from every angle but I do have a question about its quality on medium to high brightness.
On medium to high brightness I can make out vertical lines of pixels, I suppose, like on my 1366*768 15.6" laptop. I think that there is something wrong because any colored background including the virtual buttons have vertical lines that I can distinguish at mid to high brightness. Even the white block or discs wallpaper can have these lines. Can someone please confirm or deny these vertical lines? Is this the screen technology or just this specific phone that I received?
I have nexus 7 and this has been perfect in every sense. Its not as high resolution as nexus 4 but the pixels are a result of both horizontal and vertical lines colliding resulting in no highly visible vertical lines.

I am not seeing anything out of the ordinary on the two wallpapers you mentioned at max.

Yeah, I didn't know the exact term for this but it does happen. Even on whites not just background or menu. So is it almost every n4 or just a few unlucky ones because I am trying to figure out what I should do next.

It happens at medium to high brightness...Just put the brightness at high and then close in a little bit to the screen and your will notice that on those 2 backgrounds specifically the discs one. Also another way is to open up settings and then look at settings logo on the top left and you can see the blue part with vertical lines.

Again... Not seeing this. What happens if you reboot your device. Do you see it right away?

Yeah. It might takes it a few seconds but those vertical lines are so obvious. How are you not seeing them

Hmm... I'm not seeing any vert lines on max brightness... Am I crazy/blind!?

I don't see anything on mine

Look the gradient in setting very hardly and you will see them. But Nothing on white,or collored wallpaper. Just on this gradient and on grey wall paper.

Mine seems perfect as well, no vertical lines at max brightness

So many people not seeing it. Maybe it was a bad unit. I don't know how to explain it but once again I will try. When you turn up brightness all the way up the screen is bright but the way the pixels are packed they look like bunch of lines put together.
Think, shredded paper put together again to make a piece of paper. Open up a page of blue background and it should be apparent unless mine was truly a bad unit. If even then no one sees that effect maybe it was the unit that I got.
Also I'm not talking about the settings gray background lines. That'd just the wallpaper which looks like 8 bit that someone mentioned. Looks the same on nexus 7.

Not an issue with the phone
Guys, this is an issue with the wallpaper itself, not the phone. Please close these threads.
The pictures and wallpapers you see this on are simply not rendered for the high resolution
and dynamic range of the Nexus4 screen.
The Nexus4 screen is much better than what the picture was drawn on.

You will not see this if you're watching something like the Transformer's movie. I believe what Minddroid said is right. It is an artifact of the crappy image used in the settings screen.
Take a screenshot and put the screenshot on any cheap TN panel monitor and you'll see the same thing (though it is not as obvious because the monitor is a TN. If you have an IPS, it'll be more pronounced. Try displaying the image on an iPhone 5 screen and you'll likely see the same thing)
I initially thought I had problems with my display due to there being gradients on the bubble live wallpaper...but when I took a screenshot and put it on my TN monitor, lo and behold, I see the same thing.
They need to move to high-resolution images....but they won't because majority of android owners are still on low-end phones. Lol.

I see a white banding from top to bottom, size about the ON/OFF sliding button in the Setting screen, and in the position of those buttons also. I think this is a defect but it's normal as many Nex4 suffered this issue. Only noticeable when brightness is 100%

I don't have this issue, I think you should RMA your device.
Sent from my Nexus 4 using Tapatalk 2

RMA to have an other device with maybe more important issue ? Hum ...
Actually I have thse line, but i see them only at high brightness or special grey wallpaper or color. it's not very powerfull but not as important as headphone issue or speaker noise.
I'm guessing that a lot of people have these line but not seeing them.
(sorry for my english lol)

RMA is impossible when you buy an US version and you're in Vietnam. Waiting too long for the device and got some sort of imperfect product Anw, I love it, and I think most of people don't notice these lines
Set 100% brightness and use some gray background such as Settings screen, Chrome without any tab and you would see them
Sent from my Nexus 4 using Tapatalk 2

Yes, I can see them and I my eyesight ain't even that good. It's definitely not a wallpaper issue, I compare my nexus 4 to a ipad with same wallpaper at max brigthness, you can make out these vertical line on the nexus 4 but nothing on the iPad, you can't really see it unless you look for it. Most of you will say don't look for it, well what is seen cannot be unseen. Also nexus 4 probably have the worst IPS Display ever, vertical line, screen flickering, gamma issue, somewhat washout color compare to other IPS display, and worst viewing angle then other IPS display. Don't get me wrong, it's still very good, but not great like people make it out to be.

Yeah, that why iProducts are more expensive than the others. My display has 1 band of vertical lines that are a little bit brighter than the others, some kind of backlit issue, but never mind as they are only clearly visible on 100% brightness.

Nexus 4 annoying visible IPS sensors

Hey guys,
I've had my nexus 4 for a week now and I am super pleased by it. The phone runs like a dream.
The only issue I seem to be having is that I can see the IPS sensors even with the screen on!.
I'm talking about the little transparent-gray squares all over it, not about the super awesome dots that you can see with direct sunlight.
This is flipping me out!
Is anybody else having this problem with it?
I can't appreciate the beautiful screen because of this.
Also, when displaying single color frames specially dark ones, like on the clock app , the colors are not really solid.
I get this vertical stripes that are approximate to the color but not quite it.
Im posting a screenshot but I don't think that youll be able to notice it since it may be a hardware problem.
Sent from my Nexus 4 using xda app-developers app

That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Question to the OP. Do YOU see anything wrong with those images, or is it a hardware problem? I can't see any difference between your screen shots and my phone.

Damn it man, now i see them too -.-
I went to the clock app, and i can see some stripes on the left but mine are vertical.

Haha Dude that's the digitizer. Don't worry. It's all cool.

Chill out people.. Its just the digitizer that you can see, so close to the screen for better touchscreen responsiveness. The most likely reason you can still see it with your device screen on is that you have your brightness too low.. Put it up

even amoled screen are also the same

When I first got my Nexus4 the weird screen was the first thing that popped out at me. Between the visible digitizer matrix that glints when it catches the sun wrong, to the odd rectangles that can be seen behind the screen I was initially bummed and thought about returning the phone. It doesn't even bother me anymore
This is my 8th android device and the first one that has a funky screen like this, but it really isnt a big deal. Under 95 percent of conditions it looks really nice

I have been able to see the digitizer on every single capacitive screen i have ever owned.

@David_Azar I have to agree.. initially I was disgusted by how prominent the digitzer pattern was, I've never had ANY screen show it as much as the Nexus 4 does.
However, the vertical stripes you're referencing is commonly referred to as "banding". I have this on my Nexus 4 as well, most visible on grays (especially darker grays).
I have been doing some research and I believe the banding issue will reduce over time. If you check your screen when displaying a white background at max brightness, such as gmail or chrome browser, you should see a slight yellowing of the whites. It appears this can be due to the adhesive they used to glue the digitizer to the screen not curing completely. After several weeks of use, the heat from the processor will help cure the adhesive causing the yellow to disappear after a while.
I cannot say for certain that it will completely resolve the banding issue, but I have noticed that the worst banding is in the areas where the yellow tint is most prominent. I have also been testing my display every day to monitor any changes, and I am happy to report I do see a minor reduction in both the yellowing and banding (I've only had my Nexus 4 for five days so far).
Give it a couple of weeks, run some intensive games to get the processor to heat up every day. Keep brightness at max for the next few weeks and let us know if you see any improvements.
As for the pattern of the digitizer in the glass.. it's not going anywhere so get used to it. I don't like it much either but it seems to be less prominent once you start becoming used to it.
Good luck, let us know how it goes

Hey man,
Curiously enough I've never had the yellow tints everybody's complaining about. I'm used to The digitizer matrix ( rectangles) buy at first it was really weird. I was coming from a non HD display ( a RAZR Maxx) so naturally, I expected that my N4 would have a perfect screen.
I've had my N4 for almost two months now and the banding has not reduced. I made some research over the last month and I found that with some kernel settings for saturation the banding is reduced. I'm not sure if it is really reduced or the clear gray tones that have the banding just don't appear anymore because of the saturation.
The Trinity kernel reduces this a bit but like I said, your screen will look life a f*** ing AMOLED.
Right now I'm using the kernel provided by the 123 FAUX CLOCK project. I'm using the LG factory presets and for the most part I'm really happy with the screen. If you or anybody else comes up with a different solution, let others know on this thread.
Peace brothers.

Just for kicks, if you stop by a T-mobile location compare your screen with the display model and see if you can spot the yellow tint on either screen (on a white background)
I will update this thread with my phone's progress (or lack thereof if it stops improving).

I get banding issues also, more noticeable in grey backgrounds; but I can I see them in other colors if I look hard enough
I use a dark black theme to avoid looking at those bands

I can say this. I've had a ton of devices..latest was s3 and I'll just say I'm stoked to have IPS over pen tile. Just knowing HD was plagued by this alone was enough for me to ditch Sammy all together especially after seeing rgb on note 2 was no better. This is my opinion of Samsung's design ...I know why they chose it but I can't and won't buy another amoled until they get another tech in order. So now I say kudos on IPS but I'm surely a screen purest and I found these hardware screen/digitizer artifacts you speak of and to me its so much less noticeable. Your not alone. You just like good clean HD like me. Lol HTC one should be a nice one to check out...
Sent from my Nexus 4 using xda premium

That would be a little like kicking myself in the nuts. Nothing good can come out of that.
If I spot the yellow tints once, then I will always look for it. I hate doing that with the banding but it's an automatic thing.
I dunno why but it really bums me out whenever I have a problem with my phone.
Let's keep posting of someone finds a solution or something .

I've got the quite visible digitizer rectangles too. In anything less than a dark room if the phone is not on a perfect angle they are visible.
I can't really tell if "everyone's" is like that, or just some are "worse" than others.

Here's an image with them visible with the screen on (and at an angle) - difficult to take a photo of - but much easier to see with the naked eye.

Went and checked out an Optimus G today (Nexus 4 isn't actually released in Japan). Given that a Nexus 4 is just a remodeled Optimus G I thought it'd be worth comparing screens. The digitizer matrix is barely visible on the G I was looking at with the screen OFF. With it on you could almost see it at some angles. It is much more visible on my Nexus 4 which you can almost always see with the screen off and at an angle and often with the screen on.
I'm leaning towards my phone being "less than a perfect example of a Nexus 4" and not the "norm" at the moment.

they are much more noticeable in Rev 11 devices and they where barely visible in Rev 10, i am sure that there is a technical reason behind it

See that explains it a little more. Not sure I see the logic in putting a screen with pretty decent viewing angles on a device and then sticking a really visible digitizer on it though.
I've contacted the seller and I guess I'll wait and see what they say in regard to it.

[Q] G2 Screen issues?

I saw an interesting issue with 2 G2 Phones when I went to upgrade today and I wanted to see if others saw the same artifacts.
1.) When holding the screen under bright light, it looks like you can see "through" something and it appears like you can see a pattern of some sort either on the LCD itself or maybe some sort of polarizer. If this was the only thing I noticed it wouldn't have been an issue.
2.) When on a dark or black screen, you can see vertical "stripes" of dotted white lines. This was the deal breaker for me. I purchased the upgrade, they handed it to me and all I could see were these vertical stripes of white dots across the screen.
The other G2 did this as well. Were these a bad batch of G2s? Is this some sort of artifact of the IPS screen? I was coming from a Droid HD which had nothing of the sort but it isn't nearly as high resolution of a screen.
I ended up with a Note 3 because of this. It wasn't my first choice, but there was no way I could look at those stripes for 2 years!
Are any others seeing this artifact on the screen?
Thanks!

It's the digitizer. All G2's are that way I believe. Not a defect. Some phones you can just see it more than others.

OP let me get this straight, you don't like the phone because of the dot matrix you see when the phone is off and in direct sunlight?
You are right I couldn't live with looking at my phone while off for 2 years

It's when the screen is BLACK or DARK while the screen is on. I think whomever suggested the digitizer is probably right.
One of the artifacts didn't really bother me, I was more so fascinated by the pattern than anything else. To see that one the light had to be intense and direct (screen on or off) so very low likelihood of that impacting day to day use.
The artifact that really bothered me was, for lack of a better explanation, the white dots on the screen that looked like backlight bleeding through tiny vertical perforations in the LCD panel. I'm sure that's not actually what it was, but that's what it looked like to me. I'll probably end up with a G2 in addition to the Note, but I wanted to know if the ones I looked at were part of a defective batch or not.
Thanks
