Upper part of screen is darker then the rest? - Nexus 10 Q&A, Help & Troubleshooting

I'm really picky about my device screens and I've been noticing that the top part of the screen in landscape is darker then the rest on white colors. This is especially annoying in portrait. I've asked a couple people if they could see it they say it's not there but I swear that it is. I was just wondering if anyone else has experienced/is experiencing this. Thanks!

IMPORTANT: Screen

So can anyone confirm that the striations or lines on the screen are normal??
Im talking about when you pull down the notifications bar there are light lines that come down vertically and soma cases are horizontal.
Please let me know I got 30 days with it. thanks!

my first nexus s had darker whites than the display model at the store. I would recommend comparing yours with the store display or another persons nexus s, I think this is the best way, since we cant physically see how your phone screen looks. good luck
Are you referring to the gray section where your service provider is listed? Or the very dark area where the notifications are listed?
If I stare I can see some lines in the gray area.
I do see a slight grid pattern in the power control widget.
No I'm talking about grey section where your messages show up

I don't have a Nexus S, but I have a Galaxy S i9000M which has a similar (if not exactly the same) screen. If I bring up a screen that is a solid colour, I do notice some imperfections like you describe. They are hardly noticeable though.
Weird. My nexus doesn't have that and I would know, I modded my nexus 1 to be pretty much like gingerbread 6 months back, massive burn in.

actually no.... mine doesn't have any lines or defects.
the only lines are the horizontal ones separating the notifications.
I think I know what you mean. My N1 on certain backgrounds has very faint grey lines. Not always visible, even on white web pages

Why would that cause burn in more than anything else?

Yes, I can see it. I can see it on any AMOLED/SAMOLED phone I've ever come in contact with. It's the nature of AMOLED screens unlike most LCD screens. With AMOLED, each pixel is individually powered, and it's impossible to have each pixel (or subpixel) be identical, which leads to slight differences in output and color reproduction. An LCD screen is backlight by either florescent tubes or recently, LEDs, which produce an even backlight (usually) where the colors are controlled by filtering each pixel, rather than having to illuminate each pixel.
Anyway, I only really notice it when the brightness is at the minimum and it's very dark in the place I'm using my phone. If I crank up the brightness or if I'm in a well lit area, I don't notice it at all really. Although if it's VERY obvious, you might have a screen that's significantly lower quality than average... it happens, bad QC or something, exchange it.
Oh, and if you stare at a plasma TV long enough you'll notice the same thing... similar technology, each pixel illuminated individually.

Screen problem

Anybody else notice about half an inch of pixels on the bottom of the screen are slightly darker than the rest? When I have it in portrait orientation it is noticeable on the left or right.

I can't say that my unit has that problem.
It's not really easily noticeable, but in portrait mode I can see a difference between left and right. It's a faded gradient.
Sent from my Xoom using XDA App
Nobody else notices this problem when viewing a white screen in portrait?
This review seems to suggest that at least one other person has the same thing as me:
http://www.cnn.com/2011/TECH/gaming.gadgets/02/24/review.xoom.ipad/index.html?hpt=Sbin
"We did notice a slightly discolored band running down the edge of the screen on one side, but since we can't compare it to other Xooms yet, we don't know if this is a problem with our review unit or a more general manufacturing defect."
Nothing like that in mine
Honestly, its just the Xoom's crappy screen. Some people notice it, some don't. Some are more sensitive to it, some aren't.
Just like the blur on LCDs, the flicker of CRTs, and the flicker of overhead lights in retail stores.

Issue: Vertical lines of glittering dots on N4 screen

Hi,
This is my first post on xda and I am sorry for making this about an issue. But this is the first time I didn't get the solution by searching.
Since today morning, I can see vertical lines of glittering dots on my screen when viewed under direct sunlight. Its there even when the screen is off, and is as if a row of pixels have become shiny and are reflecting light. It is visible only under direct sunlight and viewed straight on, and keeps moving in left right direction.
Its not the digitizer pattern under the screen, but these dots do seem to appear along the vertical edges of the digitizer grid
I got the phone just two weeks.. And was extremely happy with it. No yellow patches, no significant earpiece buzz, some issues with microphone but that's something a lot of people face. Dont know if glitteting was always there and I just noticed today or it happened all of a sudden, but this thing has really given me a big jolt.
Phone is a white nexus 4, rev 11 build 513k. Running franco kernel with stock rom.
I have this as well and was never 100% sure if it was just the construction of the screen or my screen protector. As you say, it's only visible to me at certain angles in direct sunlight so hasn't really bothered me.
It's normal.

It's the digitizer pattern. Learn to live with it. Besides I feel it makes the phone look super hot.

This info is correct.
What you are seeing is the digitizer (used to detect touches on your screen)
Unfortunately there is little you can do about it as it is fused to the screen.
They are only really visible under direct sunlight so it's not that big of a deal. Mine look like tiny light blue dots
Sent from my Nexus 4 using xda app-developers app
Thanks everyone for the quick replies.
Just to clarify.. I am not talking about the checkered digitizer patterns which are visible under sunlight only when the screen is off.
What I am seeing is a single row of glittering dots, which moves on the screen and is there every time I am viewing the screen in sunlight, both when screen is on and off. The digitizers are visible at an angle, this is visible straight on.
Now when I am viewing something on the screen and I see rows of glittering dots moving about.. I get somewhat disturbed.
If it is expected behavior I have nothing to complain. But to put my mind at rest.. I'll try snapping a photo and uploading it tomorrow morning for you to take a look.
The dots are normal.

Those rectangular shapes are part of the IPS screen, the dots are part of digitizer.
That's totally normal, I've had it with every touchscreen device I had been in contact with. Xperia Neo, Xperia Ion, and Nexus 4.
Great!!
Now that everyone has hammered it down my head that it is normal, when I checked it today it didn't look that bad except when I see dots bounce around when I am typing
Guess a lot of it is psychological.. :angel:
So I am gonna drop this now and accept that this is expected. Thanks everyone for putting my mind to rest.

[Q] screen banding?

I just noticed horizontal screen banding on the top portion of the screen.
best recogniced in stock background pictures.
also, in phone dial screen and music app, settings, there's very noticable banding right under the blue separating line.
anyone else have this problem?

Yes, I'm having the same issues when I see it on a grey screen. I'm going to end up bringing mine back and try another one. The first one had no banding but it had white lines going through the panel as you were looking at a grey screen. Hopefully I get one that has no issues.
No banding here, post better reproduction steps to get better feedback
What do you mean?

The way I do it is that I download a light to dark grey picture and look at it in the gallery and make it full screen and I can see a different shade of grey line going across the phone.

Also wanted to know if this happens with my issues can it be a software issue to where its not telling the screen the correct color that it should be or is it just a bad panel?

I've noticed banding on mine as well using Lagom test screens. Took some pictures with comparisons to other screens.
well, i went back to the store and exchanged my g2 more than 5 times
all had bandings
i'm pretty sure they hate me there now lol
i guess i'll have to learn to live with it
sigh
I'm getting my LG G2 in a few days so it's this issue just how the phones screen is or is it something to return the phone if mine has it too
Sent from my HTC6500LVW using XDA Premium 4 mobile app
i mean, you won't notice any bandings if you don't look really close enough
I have very, very sensitive eyes
Banding? Do you mean the little dots in rolls and columns all over the screen? It it's that then that normal.
I went to the lagom link posted above and saw none of the banding or apparent moire pattern of the screens posted above. However, on a white bacground i notice a very subtle banding of discoloration going across the screen horizontally in portrait orientation. It's subtle and a non-issue to me but I guess this might be what the OP is referring to.

Just to note, the moire is an effect from the camera not the screen.
Thanks for clearing that up. No pun intended. I went to that link again and tried to notice the banding to no avail.

Stupid question, but in the dial screen, could you be mistaking it for the drop shadow of the tabbed navigation bar? I know I did at first. There's a strange amount of separation between the tabs' bar and a very thin drop shadow. Pretty strange graphic design if you ask me.
I dont think so. I do know that there is a shadow right under the blue line.
If you look at the screen close up at night, you will notice some bandings. It is too much and sudden colr shift to be a shadow.

Horizontal white lines

Has anyone noticed faint horizontal white lines running across graphic images? I've noticed this most in widgets or picture thumbnails. Tried to take a screenshot but they don't seem to get captured. Very thin lines - like just a pixel or two in width. Sometimes changing screen and coming back makes them disappear. Often if I move the screen by swiping they disappear (even with a very small movement) but then reappear as soon as I let go. Don't think I've noticed on previous smartphones; wasn't sure if this was a byproduct of the 1080p resolution.
Running stock, unrooted.

In certain lighting, I see what looks like a dot matrix all over the screen, but from what I've heard, that's normal. Not sure what exactly that is though...
I can see it the clearest when the screen is off. I think it is part of the screen tech, not the resolution, but I could be wrong

I cant replicate your problem, sounds like you my friend may have bad screen. I would request a replacement at your closest vendor.
And the dot matrix on the screen is part of the screen, essentially it is part of the touch system that you love and cherish!

I'm sure you can if you hold them a certain way in the light, you will notice it. I know on my Bionic it is visible but can only be seen if held the right way in the light with the screen off.
htc incredible was a flagship phone and had it.

Hmm... might check on that. Got the phone at Best Buy - not sure how good they are about replacements. Problem is, the issue is kind of fleeting. What I mean is these lines are not static. Even when I see them it looks like there is a touch of flashing going on, and the slightest screen swipe makes them go away. Sometimes they stay gone and sometimes they come right back. I wish I could do a screen capture - maybe I will have to just photo edit some lines to illustrate what I see

no but really, the inc was an awesome flagship ;D
and at the time i think HTC was one of the few phones that did the dots still..i remember the moto x didn't have them. i don't even know what the point of them is
I can see them on mine, but only in certain light and at certain angles and when off. I never see them when using it.
Finally got around to taking a picture of this with a separate camera. This is the weirdest issue! I can't capture it with a screenshot. It only happens on some images, and even those sometimes the lines disappear if I rotate the display. I tried doing a factory reset but that didn't help. Doesn't seem to be a hardware issue because I don't see it anywhere else except certain images (probably like 5 - 10% of them). Not app related - I've seen this happen in many apps that have images. This attachment was done in the Play Store app, on an app preview. Also seen it on Feedly, Android Central, Gallery, etc. Can't figure out what is going on!

It is the digitizer. It is what registers your touch

Did you ever find a solution to this?
I'm seeing the exact same lines after having a broken screen replaced.
me too, on my recently bought ebay G2 (VS980) - i think screen and digitizer are fine. i think it has something to do with the graphic card or rastering memory as it only happens when there is a high computational demand on display apparently? happened with two separate firmwares - one stock and one non-stock - so clearly it is not a software issue (i guess)
I'm pretty sure it's the screen. I had my screen replaced again and the issue is completely solved.
