Who makes the screens - Nexus 7 Q&A, Help & Troubleshooting

Hi,
I'm just wondering who makes the screens for the Nexus 7. Is it one manufacturer, or more than one? I bought a 32GB N7 a few weeks ago. Except for a little bit of screen lift on the right side, it's been fine. It's not enough for me to return it. But I also noticed that the screen was a bit yellow, with more yellow on the right side than the left.
Anyway, my wife really likes my N7 and her birthday is coming up, so I bought her one from the playstore. I took it out to set it up for her, and noticed that the screen is completely different. This screen is not at all yellow, and seems to be much more even than mine. But I've noticed that when light reflects off of it just right, I can actually see the web of sensors right below the glass. It's obviously most noticeable when it is off, but it can also be seen when it is on. It pretty much requires a light to be shining directly on it. On mine, if I look really carefully, I can see rows of little dots, but no web (not sure that web is the right word. Looks like a web). When off, if I reflect light off it indirectly, the LCD reflects back blue. On mine, it reflects back more greenish.
They both look exactly the same when viewing images. I can tell no difference at all. But like I said, when viewing white, mine is more yellow and uneven.
Anyway, just wondering if there are multiple manufacturers, and if not, what could account for the pretty big differences? As an iPad owner since the first one, I am used to multiple screen manufacturers.

Call the manufacturer ASAP mine had screen lift and i didnt notice until my screen randomly broke one day and the crack was right were the screen lift is. now the lower right portion of the touchscreen doesnt work and im using and external keyboard and touchpad. to answer ur question though i have no clue who makes them.

Dark patch on screen

Has anybody else noticed a dark patch on the edge of their screen? Along the top side of my screen, I can see it going off white when browsing a website in portrait mode for example.
It's like the back light isn't working properly there or something. Anybody else got this, should I get a replacement?
It's not hugely visible but it's noticeable on a white screen at any brightness level
Idk, it's up to you. I have light bleed in my right hand corner that is always visible, unless your in a well lit room on 0% brightness. I can't decide whether or not I want to send mine back though because of how common these backlighting issues seem to be.
Yeah. Mine is flawless otherwise. Its so barely noticeable I think I'll just get used to it.
Same ha ha, other people can't even spot it when i point it out to them on auto-brightness.
Yes, I noticed mine right away, but like others have said, its hardly noticeable. It doesn't bother me at all...

Same thing here. Most noticeable on a solid white background. I'm starting to think it's not a lighting problem but something to do with the way the panel is manufactured. If I hold the tablet in landscape so it's perpendicular to my face with my eyes lined up with the camera, the brightness is even across the panel. As soon as I tilt the bottom towards me, the brightness falls along the top edge. Makes it seem more like a viewing angle issue related to the way the layers are assembled or maybe a difference in pressure on the panel along that edge.
I decided to live with it because it's very rare that I have an app running in full screen that puts a light background across that area.
Same issue for me as well

I had the same issue with my first unit, did RMA and got second one. Second one had the exact same issue. Finally decided to get refund. The play store customer support said that there were few people reporting it already. This might be a design issue as well- the way device is tapered differently at the edges(backlight might not be aligned properly), two strong magnets near camera etc. Just speculating.
Dark patch here too. RMA process underway. 1/3 of screen has yellow tint. Noticeable when reading on white background. Annoyance.

Keep us posted on the replacement device!
Same problem here. I received my Nexus 10 yesterday and notice dimming primarily (exclusively?) along the long edges. While reading a web page with a white background in portrait mode I found myself wondering if chrome was adding a gradient to the edges for some stylistic effect, but realized that made no sense. I observed the same problem with Firefox, and then I installed a screen testing app and observed the dimming with a solid white screen.
It sounds like this is probably a manufacturing/design error. Now I have to decide whether it's worth the rigmarole of exchanging the device, probably to no effect. I guess this is the risk you take when purchasing a device sight-unseen.
If you bought it from a store it would still be unseen, since it would be in the box. I had the same problem with the iPad 3. It took me three exchanges to get one with an acceptable screen. All of them had dark, blotchy, yellow patches. By all accounts it's due to the adhesive glue they use. We shall see what the replacement brings. Order is currently at the 'pending' stage.
I also have this on my screen. Right side when in portrait mode. You can't see it in landscape, which is weird. My wife and I have decided to keep it, though, as everything else about it is perfect. Plus, this defect, if you want to call it that, does not detract from our enjoyment and uses.

To clarify, I meant that I'd never had the opportunity to use *any* Nexus 10 in person. Had I done so, and noticed the dim edge, it would have at least raised the possibility that there was a design or manufacturing issue.
Speaking of which, I examined an in-store Nook HD+ display unit yesterday and what do you know: it had the same dim edge issue.
By the way, where did you hear about the adhesive glue explanation?

Mine has--I assume--the same dimness along the entire length starting about 1/4" from the bezel along the "top" camera edge. It is actually somewhat distracting when reading a book in portrait mode. If I flip the screen around so that the dimness is on the left edge, for some reason I find it much less annoying. Unsure if this is a warranty replacement issue though. I haven't found another Nexus10 to see in person yet.

It was all over the iPad forums when the iPad3 came out. Plenty of people with dodgy screens. Some reported success in leaving brightness turned up to max and plugged in for 24hrs etc to dry. But may have been placebo. It could also be an entirely different cause other than adhesive. After all, what do I know? In any case, mine's heading back, but the replacement is still stuck on 'pending'
I had a rare bit of luck. Somebody sat next to me on the bus yesterday evening and pulled out an oddly familiar black tablet. I explained the problem I was having and asked if I could examine his Nexus 10. His device had a perfect display, with no detectable dimming near the edges. So the issue appears to be a manufacturing defect, not a design flaw, and something that could in principle be solved with a replacement unit.
I called Google last night and have my RMA email. I'll ship it off this weekend.

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...

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

[Q] Very visible digitizer - should I return it?

Hey guys, I recently bought an N4 (304k) as a second phone. I know there are many topics about its visible digitizer, but I guess mine is worse than the average.
For example, when I'm outside in the daytime, and I'm using the phone, then I tilt it a little bit upwards (while the screen is ON), I can see the pattern all over it. Of course it is better with white backgrounds, but it's annoying, as I can only use the phone in one angle. Inside it's mostly good, it wouldn't frustrate me if it didn't look like this when I'm outside. As I read most people only see it while the screen is turned off.
Do screen protectors make it look better? Or should I return it (I've got 5 days to do that)? Honestly I haven't had a phone with this kind of screen, so I don't know if it's just normal. Thanks for any suggestions.
It's normal. In addition, at certain angles, it will glisten when the sunlight hits it just right.
totally normal. as @janedoesmith said, if you make the sunlight hit it at the right angle you can see dots appearing instead of those patterns as well.

Misaligned screen

So I have the edge since the 11th now. And every time I have the feeling that the screen is centered to the right side, I notice it extra with a case. As the area between the bezel and the screen is larger on the left side.
This afternoon I looked with an magnifying glass and indeed saw that this was indeed the situation. It is about 0.1 mm or so but oh so annoying. Luckily I can exchange it, however there will be only phones I stock around the 30th. Keeping mine thill then.
Are there others with the same issue?
The attached version is not my phone, but just an example to explain.
To better understand what i mean I attached a picture. I have the black version but you could see it as the black line on the right side of the phone is thinner than on de left, so the screen is essentially to far to the right..
not the best picture for judging...
But I know what you are talking, I have seen a few devices now and all of them were different in terms of screen quality and alignment!
for me, the worst problem is the uneven contrast (darker sides) on most of the screens. i own 3 devices now and all of them have display flaws. two suffer from a yellow tint when tilting, the other screen has a slightly darker left side... :|

I know. When my S6 comes back from warranty repairs I will try to make a picture. The S5 I have laying around can't focus clearly enough.
Well I hope I won't have a replacement with tint issues or such. Because my screen is, aside of the alignment, pretty perfect. Maybe I'm a bit nitpicky but I think that's justified with these kind of price tags.
I still have till the 30th to get used to it or exchange it. An order for a replacement has been made.
People complain about issues of screen color when tilting the device.. When are u ever tilting the device? U should be looking at it dead on anyways.
Honestly I don't see anything from ur picture, maybe ur just crazy.. If it is a little little misaligned who cares.. It's the curve part anyways..

The picture I used is just to explain what i mean with the black lines on my phone. Imagine that picture with no black line on the right of the phone, so the screen blends in with the white. And a bigger black line on the left.
That's what i have, but my phone is black so i cant put it on a picture to explain it.
I can really only tell in a dark room, but there is ever-so-slight light leakage where the glass meets the metal on the bottom of my S7 Edge. I see the slight leakage on the bottom-left and bottom-right. Doesn't bother me much, maybe a little, but my experience with smartphones is you'll be lucky to find one with absolutely flawless everything including screen alignment. It's often not worth exchanging for a new one, which may have other issues. Plus there's the whole issue of setting the phone up from scratch again. My device seems to be working fine (this is my 5th day with it) so far, so I won't be exchanging it.
After reading this thread I checked mine and its is misaligned like you described. I then went to Samsung and they checked and said that its normal. Now that I see it, its driving me crazy.

Same **** with me. My screen is also misaligned and its driving me nuts with this phone price i dont know what to do about it. I have s7 edge btw same **** all over with the s6edge. I really didnt notice it when using the phone. I noticed it when im checking out the phone looking how pretty it is then when i turned on the screen i noticed that the left side of my screen has a thinner black bezel and when i look on the right it has a little bitty gap.
