I searched around the forums and did not see anything else posted about this. I just bought the WiFi only Xoom and am very happy with it, except for the fact that the bottom edge of my screen is darker and dimmer.
To clarify a little bit, I mean the edge of the screen thats next to the ports on the bottom of the Xoom. Normally its impossible to notice since I usually hold my xoom in landscape and there is the black bar at the bottom. If I open a pdf file or ebook, and then view it in portrait mode, I notice a darkening of the screen along this edge. It kind of looks like a shadow or a very slight black blur. The darkness is not that exaggerated but once I noticed it, I could not stop looking at it when reading.
Now I normally go on a witch hunt for problems with new devices when I first get them. The more I pay for them, the harder I look. I thought at first I might be doing this with the xoom and kind of blowing this out of proportion, but last night I was showing it off to a friend and he noticed it before I even mentioned it.
Does anyone else notice the darkness along the bottom, or do I just have a defective panel? Its easiest to see if you put your brightness around 80% and then display something that has lots of white, like a pdf or ebook, and then hold it in portrait mode.
I will post pics of it when I get home tonight.
i've noticed on all the xooms i've looked at too, including the one i bought. someone once replied that it was defective, but i think it's actually how it's made.
most people's eyes may not be sensitive enough to notice this i suppose.
I hope this is not the case. This might be a deal breaker for me since I need a device that I can read on a lot.
Can anyone else verify this?
Mines not like that. I'm using the Verizon one. I use it in portrait often.

i just exchanged my defective one (had wake issues) for a new one and guess what - dim bottom too.
that makes 8 xooms i've looked at that have the dim bottom. it's only noticable on white/light bg and if you don't have your menu bar covering it.
i picked up the wifi xoom yesterday and noticed it when togglieing the bottom right corner setting button (battery indicator). When looking at this the entire right portion of the screen dims. Other than that, it is not noticeable.

This is a purposeful UI effect (what you are talking about, not the OP).
For the OP, I looked at my Xoom diff brightness levels, angles, orientations, etc, cannot see any dimming. 3G model. Not very helpful, I know.
also, if you look at the top of the screen (landscape mode) at an angle you can see the light source. the lighting just isn't even. i'm positive that if i look at anyone's xoom i'll see it since the back lighting is made the same on all... unless they switched mfg's in production like the evo4g's did.
Well thats a real bummer. I think I might just hold onto mine for a while and maybe try and do a warranty replacement later in the year if they fix this issue.
Did you notice any 3g models having the dim bottom, madsquabbles? Or for that matter, has anyone noticed this on the 3g model?
I first noticed it on the 3G. thats when I posted my first question.
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...
Sent from my Nexus 10 baby!
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.

I would love it if you would come back and post if the replacement has or does not have the issue.
Hello,
I have received Google Nexus 10 and it seems like the seal was broken, which suggests that somebody else has already used it (or at least unpacked).
I guess that the only known "big issue" is the light bleed. Could somebody tell me, step by step, how to determine it? (e.g. how to load all black screen? What brightness should I use to check it?). I am trying to judge whether to keep the tablet or not.
Thank you for help,
Theriel
Try using an app like this LCD test:
https://play.google.com/store/apps/...DEsImRlLmxhcHBlLnRpbS5hbmRyb2lkLmxjZHRlc3QiXQ..
go to the pure black and then play around with the brightness (set it to max).
You'll almost certainly going to see some but this should help you decide if it's a deal breaker for you.
the darker the room the better aswell! if you are in a pitch dark room and only see little light bleed at max brightness then have a little smile to yourself and enjoy the nexus!

So what is light bleed that matters?
I know the OP's question is on testing for bleed, but want to respond to help those wondering whether what they're seeing in their tests is normal or a defect that a replacement unit might solve . . .
Starting with a couple of suggested definitions:
'Light bleed' is a significant unevenness in screen lighting/brightness that's irritating in normal use – like scalloping along the edges, or being a lot brighter or darker on one side. Separately, let's call it 'black glow' when what's intended to be jet black on a screen doesn't appear completely black.
If you search the Web for 'light bleed' and the name of any major tablet, you'll find plenty of references to this. When examining your tablet, for context do the same with your laptop, LCD monitor, and LCD TV, for all are subject to the same concerns. No screen technology is perfect. Lighting on all LCD screens varies somewhat depending on the angle you look at it, and some level of 'black glow' is normal too.
Looking at your all-black screen in a dark room with the brightness turned up can be a useful test to verify problems if you find concerns that affect normal usage. This is a worst-case-scenario video test, and when you test your other LCD-screen devices this way, you are bound to see 'black glow'.
A lot of cell phones (mostly Samsung) have AMOLED screens that don't need screen backlighting & thus don't have 'black glow' – each pixel is a light and blacks can truly be black. But these screens are limited to smaller devices – the largest are two lower-resolution 7.7" units; you can't buy a 10" AMOLED tablet. With LCD's, note that the larger the screen & the higher the resolution, the brighter the backlight (really, it's on the edge) needs to be.
There are definitely defective units out there, and some that aren't as even as others. Hopefully this adds context to the discussion and will help folks new to the issue decide whether their unit is bad enough to be worth exchanging . . .

Mine is faintly noticeable all the time with auto brightness on. I asked for an RMA and it was 2-3 times as bad. I think I will keep this one. As of now looking at it really bothers me, but I know in a few months once this device has some wear it won't matter to me. However I am still debating on attempting to receive a refund and possibly buying it in the stores in a few months. Hmmm lol.
Thank you all for your informative responses.
I am attaching the pictures of my case. I guess I will have to return it - although you cannot see in the light and with non-black background, it is pretty annoying when the background is black and the ambient light is a bit dimmer...
What would you do in my case ? How does this case compare to your cases?
Thank you,
Theriel
my orignal device has servere light bleed on the left corner and my replacement device has servere light bleed on the right corner... 3rd one is on the way, please Google, give me a acceptable screen before the world ends!!
I do not think there is any point of returning it. It seems liek light bleed is inherent in the design of these tablets. I have two right in front of me, the second one has even worse light bleed. I shall be keeping the first one. Does any one know if they will charge my card for the second one. It seems like they charged me card, then a days before I got a second nexus 10, they removed the charged.
I was expecting a courier to pick up my old nexus 10. But no one has. Any one else in the same situation with 2 nexus 10s?

They will place another hold of the price of the device until the rma'd unit has returned to them. It would take another 7 days until the hold is released from what was explained to me. So at the moment for me they have 1k of my money on hold because the original is in route to them now and I had just ordered the replacement for the replacement!
You will have to setup a pickup or go to the nearest UPS facility to return your defective unit.

Yes, I was thinking that. But they do not have any of my money on hold. They did but then it was returned back?! Keep checking my account. I thought they were going to organise the collection of my old devise. Seems like i shall give them a ring. They may charge my card again!
So... what do you think about my case (see photos in the previous post)? How does it compare to the "average Nexus 10" you have/have seen? Is it "ok" or "one of the worst cases" or... ?
I am not sure if it is not worth waiting 2-3 weeks for a new tablet, as opposed to holding onto a defective one for a few years...

Your one looks bad!
@OP: It seems the question should be whether your screen looks great to you in normal use or not. If lighting evenness irritates under normal use, *then* the dark room/full-black screen test can confirm what you're seeing. Is only time you see a funny pattern when testing the thing this way?
We can't really know if a picture taken with a typical camera in a dark room really reflects how you see the image; most cameras normally crank the gain up 'till there's some kind of funny colored image. My screen is a bit brighter in the lower right when running this test -- which I see as nothing more than an interesting detail about how the backlighting works, it's completely irrelevant to me in normal use. If your picture really does reflect what you experience, and it affects normal usage . . . yep, it's worse than mine.
The easiest way you can get context for what you're seeing is probably to run the same test on any laptop or tablet you can get ahold of -- makes sense that you don't want your tablet to come up short when compared to what you see first-hand on other LCD screens. That's probably a lot better way to decide!
So the Nexus 4’s potentially quality screen has crappy screen issues. There. I said it.
What I mean is that it’s a GREAT screen in some ways (resolution mainly) but it’s let down by what seems to be noticeably poor quality/manufacturing.
Why do I say this? Well, it’s been my experience that the Nexus 4 (in general) has a chronic problem with significantly poor screen uniformity for both colour and brightness. I ordered my first phone on the 13th December 2012 and as soon as it arrived I was pretty excited at finally getting a new phone (upgrading from Galaxy S1 the N4 is a beautiful beast).
When I booted it up and started using it I immediately got a sinking feeling as I realised that the bottom third of the phone had a slight but easily noticeable yellow gradient tint to it along with the left edge and the right edge was grey/dingy about a half a centimetre in. The left side and bottom third were also noticeably brighter than the right side of the phone. I’ve illustrated this in the attached pic. It’s all fairly subtle – but it’s definitely there and is easy to see.
Since I use (like most people I guess) quite a few apps that have white or solid colour backgrounds (gmail, currents, google books, email, messaging, chrome etc) – this lack of uniformity really made things look crappy in a not spectacular but just “sub-par” way unless I was viewing something which was a picture or video or filled the screen where it wasn’t noticeable.
So I called Google Play and told them about the problem and they arranged for a return.
When I got my replacement I booted it up and immediately, even before getting past the X logo animation noticed a big spot of light bleed at the top right. *Very* easy to see and my heart sank.
There on in I opened up the Mail app and closed the keyboard so I got a nice, mainly white screen. Again I noticed the same issue with the yellowing tint to the bottom and left but this time it was *more* noticeable.
To cut this long story short I’ve now sent back 3 devices for this issue, about to send back my 4th and my 5th should arrive tomorrow. I’m not holding out much hope.
I’ve seen this exact same issue on about 4 other Nexus 4’s in shops in the UK (Carphone Warehouse, O2) and while there looked at the HTC One X, iPhone 5 and the new Lumia phones from Nokia running Windows Phone 8. Those phones in particular (with LCD screen tech too) didn’t have these issues *at all* as far as I could tell. In fact the HTC One X screen looked to me to be flawless, as did the Lumia 820 and 920. If I could put the screen from the One X into the N4, I would. Sadly, not gonna happen. Sadly I don’t want the One X but do want an N4. P.S. I know LG manufacture their own displays.
Now I’m NOT claiming to speak for ALL N4’s (why I’ve started this thread) but I do believe that it cannot be a coincidence that ALL the N4’s *except one* showed this issue. I believe that LG simply manufacture the screens in such a way that they invariably have these tinting and brightness uniformity inconsistencies and that because most people don’t care, they don’t care.
********What I’d like is to ask if people with an N4 they’re happy with could do the following and provide the following info:
*Open the Mail app and close the keyboard (press down arrow at bottom). Look at the white of the screen and see if there is any edge or part of the screen that is noticeably *brighter* or *more yellow*. Are there any areas of the screen that are noticeably darker or duller? Do this for different brightnesses (low and fairly high). What do you see? Any yellow tint? Any inconsistency in brightness? All ok? Perfectly even?********
TL;DR: I’ve had 4 Nexus 4’s from Google Play all with the same yellow tint and brightness uniformity issues. Very noticeable. Not acceptable to me for a device that displays a lot of white “pages” and solid colours. Other phones (that I don’t want) do not have this issue (annoying). Please can you give feedback from your phone.
PLEASE NOTE:
Other threads discussing the “yellow tint” issue invariably attract trolls in their varying forms.
DO NOT reply to this thread if you simply want to say any of the following:
1) I don’t see a problem with mine therefore I don’t understand what you’re talking about.
2) I don’t see a problem with mine therefore you’re imagining a problem with yours.
3) I don’t see a problem with mine therefore you’re expecting a “perfect” screen and they don’t exist.
4) There are more important things in life to worry about. (A: I’m not “worried”, screen uniformity is important to me, get over it.)
5) I see a slight yellowing but I don’t care therefore you shouldn’t care. There are more important things in life to worry about.) [see above]
The attached illustration is slightly "exaggerated" to make sure the effect is reproduced for all screens. Not by all that much though.
UPDATE: 31/01/2013: Well I've received *another* N4 replacement today and lo and behold the exact *same issue*. With this one I'm going to wait it out at least a week and see if it improves. I *really* want an N4 as in every other way it's truly a great piece of tech. Pray for me guys!
Re: [Q] General poor screen uniformity - brightness and colour - Feedback Please!
My screen has no discolorations or brightness unevenness that I can see.

I've had tint issues with all three handsets. First two it didn't disappear after use. This third handset SEEMS to have gotten a little better after a week.
All three had light bleed. First one was least noticeable, last two including the current have two blobs of light bleed in the exact same places along the top of the LCD.
It's almost as if something during manufacturing (screw tightness?) has caused it on both handsets. They are both 212K and revision 11.
It's annoying me and I may do one final RMA once I see what this new wave of devices brings.
mine's fine.
I did what you asked, OP and I'm not seeing and unevenness, yellow tint, or brightness issues (aside from auto-brightness being stupidly low).
The only issue I have with my screen is poor colors. I have a One X and an iPhone 5 that I sometimes compare with my N4's screen and it's shockingly apparent that the N4's screen has colors that just aren't worthy of a top-tier device. The resolution is nice and all, but I like it when the colors are nice and accurate. It's most easy to tell when comparing images of people and looking at their skin. Now I'm no anthropologist, but I have a pretty solid grasp of what skin looks like. The One X is probably the best at representing things the way they look IRL, followed by the iPhone 5. I don't know if it's just my N4 or other people have the same issue. I've tried using apps to adjust the color (FauxClock with Faux's kernel, to be specific), but nothing makes it look quite as nice as my other phones.
I guess you never asked about the second part, but there it is.
I had that issue when I received my device, Used kernel setting to rectify the problem but after 4-5 days of use it gone away. Now device is perfect.
I recommend you to stay with it for 3-4 days before returning it and check.

Thanks for the feedback - very helpful. I got *another* one through today and it seems "better" by a bit than the previous one at least. I think I'll see how it goes. Good to know that it's not only me sho can see the difference.

All the phones I've had have been 301K and they've all had the same issue with yellow tint/backlight inconsistency in a very similar way. I'll have sent back 4 N4's if I decide to keep the current one! I think you're probably right about the screw tightness or some such other minor thing during manufacturing. It's not like a viewing angle problem. It does look like something to do with assembly in particular. Please do let me/us know how you get on and how things work out.

I had that issue when I received my device, Used kernel setting to rectify the problem but after 4-5 days of use it gone away. Now device is perfect.
I recommend you to stay with it for 3-4 days before returning it and check.

I used FauxClock on my previous device (sat here waiting to go back) and it did seem to improve the situation slightly - but then since the screen isn't uniform, it reduced the yellow where it was yellow but then made it too "blue" on the rest of the screen. I really hope that this yellow tint is a "glue" issue or something that will even out through repeated use due to heating/cooling - i.e. expanding and contracting which somehow settles things down. I'll keep this one about a week and see what happens. Fingers crossed!
Thanks for your feedback guys!

^ this is pretty much all I can say.
Every nexus 4 phone I handled had a slightly yellower screen at the bottom. For me its barely noticeable, not as yellow as it is in your illustration.
They all seem to have that same issue, along with light bleeding across the top edge.
You can keep RMAing if you're not tired of that .. But you will not receive a fully uniform no matter what.
If screen uniformity is important for you get one of the above phones you mentioned.

Thanks for the info, that's interesting to know. Out of interest, how many have you handled? Going by some comments on XDA and around the web regarding this issue, you'd think that the yellow tint was only on a handful of handsets and an isolated quirk, not as I suspect and you seem to suggest, a common trait of the N4.

Well,
I ordered three of them, all screens looked identical with the exact same issues: some yellowing at the bottom with a light bleed over the top edge (especially top right corner). I had to RMA 2 out of the 3 due to severe screen issues (screen flickering and dead pixels). Received 2 new units, screens have the exact same issue. I have 2 friends with N4s and their screens are like that too. It's almost not noticeable.

Does the light bleed appear like small blobs from the top edge?
My worst is the top left, about an inch in. Then there's another smaller blob nearer the right hand side. Little bit leakage top right and top left, but its worst along the actual taskbar.
I will take a picture tomorrow.

My first nexus 4 (rev 10) has perfect whites except the bottom of the screen would turn yellow after warming. All of the 4 RMA devices I've recieved (rev 11) don't have this issue EXCEPT all the rev 11s are calibrated horribly leading to the entire screen being yellower than my rev 10 unit. The screens are uniform, however, I just wish they calibrated the phones like they did with the rev 10.
The new rev 11s have a calibration problem while my rev 10 has a glue problem.
The new rev 11s also have a dimmer screen than my rev 10. I kinda just want them to send a perfect rev 10 to me.
Interesting because calibration issues affect the whole screen. If any part of the screen isn't the same "tint" as another part and its noticeable then this isn't something that can be fixed with calibration. Calibration can only save a uniformly "yellow" or "blue" tinted screen. To that end I wish mine was uniformly yellow. Mine is a rev 11 and I'm on my second day with it and hoping the bottom and left yellow tint fades soon and that it's just glue. I've tried Fauxclock and applying various screen tweaks with a previous similar phone and it helped somewhat but there's nothing can be done about unevenness in the tint really unless its glue and it dries.

Hey,
Thought we could have a thread to document Light bleed and how it varies between device (apparently).
Here's a potato quality version of mine: http://imgur.com/YzFs4uy
It's not too bad but I can notice it on dark screens particularly the bottom left corner and top right. Wondered if it's worth RMA'ing or if this is similar to what people have on theirs. If it's bad by the average then I'll return.
Just thought this could be a useful resource.
Wow, that's bad! Mine is barely notable, only on the top it is visible of the status bar is colored.
I've just started the RMA process for my Nexus 9 because of the light bleeding right across the whole top edge of the display (and because I can't increase the volume on it without digging a nail into the button!).
I though I could ignore it but with the way all the material design apps colour in the status bar they status bar looked like it was always a gradient as opposed to a solid block colour.
I was in two minds whether or not to RMA it or not but came to the conclusion that if I went today to trade it in at a shop (for money or in part exchange for another product) with the condition of the screen and the button I wouldn't even get the a top trade in value for it even though it's only 2 days old.
I'm hoping that the unit that gets sent out to me is in a much better condition.

Mind posting a photo? Didn't think mine was that bad really? Think the potato quality might make it worse.

How was it in comparison to my picture? Not sure if to RMA or not?
There is already a thread in the help section with quite a few pics and posts of people with light bleed.
http://forum.xda-developers.com/nexus-9/help/notice-light-bleed-t2927824
So like everyone else has notice, I have some light bleed as well, but I don't notice it unless I load a black wallpaper. I am not sure if I will return it or nor as I don't usually run a black black wallpaper.

Mine looks virtually the same as yours. One big patch of light bleed on the upper right (viewing in portrait mode) and 2 small patches along the lower corners. I'm on a White 32gb.
My advice is return for an exchange or RMA'ing, whichever you think is faster.
If bought locally, exchanging is the way to go.
I found a video on Youtube of someone claiming that his doesn't have lightbleed: https://www.youtube.com/watch?v=QrT0GAaPgoQ
Take this video with a grain of salt though because I think the camera he is using is on VERY low exposure to the point where you can't see the backlight.
Am I the only person without lightbleeds?

Maybe. I don't think i've seen an example of one without.
Lightbleeds are most noticeable on a black or very dark screen. You got a picture you can show us of your tablet?

Looks to me your a minority ? my 2nd unit comes this morning, see how I get on with that ?
I saw on reddit that several people are mentioning that this problem only exists on the White model. Any truth to this?

No, a fair few people with Black versions also complained.
I think I'm going to return mine, frustrating but for the money it shouldn't be hard to not have this non-uniform lightbleed
This is ridiculous.
I have the white 32gb btw
Mine seems barely noticeable so there is hope for those that want to do an RMA.

You RMA'ing?
Looking at the pics I'm glad mine isn't nearly as bad..there's one bottom left corner on my white 32 that has slight bleed but nothing like the ones you all have posted...
I have 32Gb white, but I don't see any extensive light bleeding on my unit, nor wobbling back panel... I'm extensively using my device for past 24 hours, watched video, news, web browsing, and haven't noticed any issues with extensive light bleeding. I'm not even noticing anything like on the pictures from previous posters.

Yes sir. Just drop it off at ups office. I'll get one later, I'm hoping it's just this initial batch that's detective.
Do we/you think we going to have this issue on 4G/LTE version of the Nexus 9, because I'm thinking of buying either the Nexus 9 or the nVidia Shield Tablet 4G/LTE
