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

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.
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.
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?

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

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.
Sent from my Nexus 4 using xda app-developers app
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...

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.
Dear Friends,
In peripheral vision, I can see a the 6p screen flickering slightly. Mostly only noticeable on bright white and green screens on full brightness (without auto brightness adjustment)
Can you please do me a solid one and check it out on your device?
1. Turn Off brightness adjustment in Display settings
2. Set phone to full brightness
3. Load a completely white background (chrome browser starting page or any screen testing tool)
4. Hold the phone centrally close to your face and look at another object in the room while viewing the phone in your peripheral vision
5. Look back and forth at the object in the room and at the screen to see if you notice a slight flickering or restlessness in the screen
The flickering is very faint and hard to notice in peripheral vision but it is definitely there. I tired the same with an iphone 6plus and the iphone screen (my brothers Iphone, I'd never buy none) definitely has no flicker at all. It's very steady.
The screen is also not as bright as the iphone 6+ but I think that is well known.
I'd like to know if it is standard with all nexus 6p's and if it bothers you at all.... maybe I am just obsessing or maybe not and I need to RMA the device which is a huge pain in the ass.
Thanks!
Thomas
I do not have this issue at all. There are two possibilities, there is a defect with your device OR you are sensitive to the refreshing of the display. However, most modern displays have a refresh rate of 60Hz or higher (I assume the Nexus 6P and iPhone 6 are 60Hz, but I cannot find that info) so it's odd you haven't experienced this with other devices.
My best advice is for you to get your hands on a different Nexus 6P to see if you have the same problem. If you can't do that, I would suggest you try to see if you notice it in any other displays. Maybe go to a store and try it with a Samsung Galaxy S6/Note 5 as those have a similar AMOLED display, whereas the iPhone is LCD.
Thanks for your quick feedback. I am really surprised that noone has noticed this. I am looking at the device straight I don't notice it either it is only in peripheral vision that I can see it but even then it is very hard to catch. I think that indeed it must have something to do with the refresh rate of the screen.
Maybe other people can give it a try ? I have a gut feeling that it is an "issue" in all Nexus 6P devices but that most people don't notice it because it takes a very malicious mind to see it. Maybe it's because the device is brand new and the screen needs some time to "break in" or "adjust" ?
I just want to make sure that I don't have a defective device.
Thanks everyone

I have heard of that before, but you're seeing the issue on super high brightness. Perhaps try it on a lower brightness to see if it worsens.
PWM (Pulse Width Modulation) is used for making the display darker. For example, say that a phone has a 60Hz refresh rate, meaning all of the pixels update 60 times each second. To make the display dimmer, the pixels are on for a shorter period of time in between each refresh. For maximum brightness, the pixels are on for the entire time between each refresh. Thus, when the display is dimmer, some might notice flickering as the pixels turn on and off.
Billy, again, thanks for your response. I will give it a try.
The best way I can describe it is that the effect is extremely subtle; so much, that I don't notice it looking directly at the screen but it translates into a sort of "nervousness" of the screen in general because you are left with the feeling that the screen is constantly moving and not really 100% steady. I am not sure if it is something I can/will get used to over time but I am willing to give it a try for a few days.
I am also almost certain that I don't have a hypersensitivity of some sorts but rather that all Nexus 6P phones have this issue just that most of the people don't really notice it.
I'd love to hear from others about if they see it
It's normal, it's caused by PWM. I don't notice it much on my 6P,my Note 4 had it much worse. Some people are more aware of it than others and seem more succepatble to seeing it.

So you are saying if you really pay attention to it, you WILL notice some of it for ANY person, right?
I have a Galaxy S6 and I have not noticed it there. Does that mean that the S6 is not using PWM ?

I think the S6 uses it also but some phones seem worse than others. As I said, I can see my 6P a little but my Note 4 was worse, I could see the flicker all the time.
I just checked my S6 for the issue (side by side with the 6P) and I can say with confidence that the S6 does not have the issue AT ALL. The screen does not flicker in peripheral vision and as a result appears steadier and calmer in general.
If i hold a video camera over each screen I can see scan-lines moving diagonally upward in regular intervals/spacing which both phones, however the lines are stronger and more visible with the 6P Screen. Which in my humble option explain why I am noticing this effect. I am just not sure if something like that warrants the effort of returning or swapping out my 6P
It doesn't really bother me but knowing that maybe other 6P devices have it less makes me think because I shelled out 699€ for it....
What would you do?

Does it get worse on the 6P when you turn the brightness down? How about on the S6, if you turn the brightness down (which should exemplify the PWM issue) does it have the same effect as the 6P?

Thanks for asking. When I turn the brightness down on the 6P it gets better; the effect is not noticeable anymore when it's set on 50% brightness. As soon as I have it on 100% I can see it from the corner of my eyes when set on a white background.
The question is really if I can expect it to be different on another 6P or if all the 6P's have this level of subtle "flickering" if I may call it.
I suspect the latter... and from this point of view it doesn't make sense to swap it out. if you are able to notice it ever so slightly on your device then changes are that it is present on all devices and that the 6P just has it more than for example the Samsung S6 because on the sammy I can't notice it at all, even on full or low brightness for that matter.
As you've said , if it were a PWM issue, It would worsen with low brightness, correct? In my case it worsens with high brightness. So what really is it then?
Quick question... Under normal day-to-day usage, you look at your screen out of the corner of your eyes and have the brightness set at 100%?

You're asking the right questions here and the answer is no to both ?
However I hope your can understand my concern because in the beginning nothing is more important than having a flawless device to my very rigid mind.
Also im worries that the screen in general is not calm as compared to other models such as the s6. Basically that since the flicker is present I might still perceive it even when looking straight at the screen.
I decided to order another 6P to be able to compare the 2 and see if the issue persists on the new device. Depending on the outcome I will keep one or return both. The flickering is really evident and IMO unacceptable for a device with this pricetag.
I am not sure if this is the same thing, but see the flicker in the attached video. It's at 5th,10th and 15th seconds. But then I checked it on Galaxy S4 and see it there as well. I don't notice it in any other screen. May be NBA app is causing it.

I have been searching for someone, anyone, who has this issue as I do. Everything you said previously, I experience as well. I've had a 6p since November, and the flickering was there from day one. It's easy to notice at >50% brightness on white or greenish screens. Less so on red and blue. It's something I've gotten somewhat used to, but sometimes it really bugs me. Have you had any success with trying things?
I have recorded the screens of the 6p and 5x. The difference and flicker of the 6p is clear.
