Are any of you experiencing light bleed like the ASUS Transformers are experiencing?

I did with a dead pixel... I called Samsung and they will repair it.
But what about light bleed specifically?

yes.... check out the other threads.. people are reporting them with lots of tablets. The black bleeds yellow.
I just sent back my Transformer, and preordered this tab. The sleep issues and the light bleed are no worth getting that device. I tried to talk to tech support and they told me to take out the battery. that I could turn it over and pop it out like a laptop battery. Then they told me basically that if I didn't charge it for 8 hours it wouldn't work. ASUS Tech support was a nightmare. Samsung was a little slow with updates to my captivate... But I still love em. If this has a little bleed I wouldn't be too worried with it. It's the nature of backlite LED screens. It even happens on high end monitors and TVs. Until they come out with something else... It's going to be an issue. you just have to keep sending it back until you get one that doesn't bother you... that or turn down the brightness. In order to get it to do it you really need to crank up the brightness and walk into a dark room. IMO that's not to practical for normal use.

I didn't see that black /yellow bleed thing. I would like to see that. I would just send it back.

Light bleed usually only visible in the dark with dark screen backgrounds. I saw a review today on YouTube from mobile tech review and when they show some movie clips you can faintly see bleed lower right and right side.
this is what I was asking about

I haven't seen that yet. Where the colors are messed up like that.
Luckily no dead pixels and no light bleed.
my limited edition tab has backlight bleed and a dead pixel, I wonder if I can even get it repaired or not...

Yes you can...search some of the other threads for the io support link.
Bought a retail version at the Union Sq Best Buy here in NYC, one spot on the screen (less than a square inch) would show "liquid" under the screen when depressed (I noticed it when I was wiping my fingerprints from the screen). Exchanged it hoping to get a grey model,but got the white one again.
Well that one had a slight light bleed on the button left corner and was only noticeable when the honeycomb controls disappear.
Today I exchanged it for another one, and it looks like a keeper.
No light bleed or dead pixels, at least none that I can see. Hardwarewise my tab seems perfect.
Model GT-P7510
Mines the new 32g model and I don't notice hardy any bleed at all on the screen... even after carefully examining the edges and trying to view at angle to see under the bezel I don't see anything I would call a bleed issue. Actually also having an Ipad I love screen on the new 10.1
I have both and I have absolutely no bleed and dead pixels on the GT.
Sent from my badass Galaxy Tab 10.1.
same here, no bleed and no dead pixels. I can actually us this as an snooker reader now. the TV and load don't get dark enough. I read with red text on black. even at fu- brightness there is no bleed.
I have light bleed in the bottom right corner. I noticed it right off the bat. I'm exchanging it tomorrow. Let's hope the next one doesn't have the issue!
Yeah, thought mine was perfect, then noticed in the top right corner there is a spot about 1“ square. Didn't notice it until I booted up in a room with dim lighting. I might go exchange it out.
I bought a new Note 10.1 at Bestbuy yesterday. Got it home and was enjoying it until I watched a movie in letterbox in a dark room and noticed a "white glow" coming from the bottom left hand corner and shining across about 1/5th of the screen. Never would have noticed it in a normally lit room but in the dark was quite annoying.
Anyway, check yours and make sure it doesn't have this problem. I returned mine and got another one that did not have the glow.
Great :/
Any dead pixels? Just got mine also today, but have yet to open it... crossing my fingers, lol
Ugh, just opened mine and checked it... I also have light bleed in bottom left corner, but even worse at center top of screen as well. Also found a small curved line of dead pixels, shaped like a letter C that is very noticeable on a white background. This sucks, taking it back for an exchange.
I will say this, definitely a very fast snappy tablet, but the low screen resolution is unfortunately noticeable. :/
How can i check for lightbleeds btw? dead pixels i know how to, but lightbleeds, no idea.

Just watch a letterbox movie and look at the corners. There will be some slight glow present but it should be even on all corners and not look like someone opened a door from a lighted room to a dark one.

Exchanged for another, a bit of a pain, they had 3 employees trying to find the dead pixels...
The new one has almost no light bleed, very slight in the bottom left corner, not a big deal though. However I did find one dead grey pixel... weird though, it only shows up on certain shades of green and dark gray. Can't see it at all on a white background and I guess that's what's important, so I'll probably just keep it.

Yes the problem with employees looking for defects is that they are looking at it in a bright room. Also, if it is BestBuy there is an excellent chance they are also idiots.
They make some apps for LCD screens that try to fix dead pixels. You may want to see if they make one for Android.
I'm gonna do another exchange on Tuesday, the dead pixel is driving me nuts, lol.

At BB now, just exchanged for 3rd and opened it before I left. Lo and behold I see a dead pixel in center of screen, lol. They're bringing out #4 now... :/
Update: #4 also had 2 dead pixels, unreal! They're bringing out #5, last one in store, lol
For those wanting to check their screens you can use ES Taskmanager from one of the android stores. It has ascreen checker that fills the screen with solid colors to help find dead pixels and to check color purity. You can use the black color in a dark room to test for back lighting bleed.
I like this guy's:

Btw, Gnote #5 was a winner, no dead pixels! Amazing I had to go through 5 of them, new record for me. They hate me at that BB now, lol.

Thanks for the tip. No dead pixels - checked twice. I'll check for bleed tonight.
Note to everyone. Any tablet will have some small light bleed when looking at a totally black screen; however, it should be consistent between each corner and edge and very slight. If there is a noticeable glow that extends 1 or more inches you may have a problem.
Lol, yeah i know BestBuy HATES people returning stuff and they must have been pissed you blew through 5 of their new tablets. Man that is some serious quality control issues from Samsung. These guys are getting sloppy.
Well the 2 tf700s i returned had lightbleed real bad. This one has it at the top. So bummed out. Will have to return this one now.
2 transformers and soon to be 2 notes.

I have some light bleed in both of the bottom corners. They are clearly visible on 100% brightness in a completely dark room while displaying a black image, however when the brightness is set to 0% I can only just make out where the bleed occurs. It's almost a yellowish hue and spurts off the edge of the display a few millimeters. Now with auto-brightness on and just using my device it doesn't really jump out to and when showing it to others they couldn't even spot it when I told them to look for it. I just wondered if others were having this issue and if it was worth it for me to try to RMA another one. Funny thing is I just turned on my old 7 inch galaxy tab 2 and it has some bleed, but its not nearly as noticeable. As someone was saying I just wonder if a larger percentage of these have light bleed then those that don't.

IMO, if you have to sit in a pitch black room and crank the brightness up to 100%, then I would definitely keep it."Too much" is hard to define; many ppl here will RMA until they find a "perfect" unit.
I've heard ppl say that not all devices have bleeding, but in a world of mass produced products, screen bleed is just a side effect of consumer demand.
My family uses both Apple and Google/Android products. This includes 1st gen iPad & 1st gen iPad 2, and 3 android tablets made by HP, Asus, and now, Google. They ALL have screen bleeding. (HP being the worst of the five)

True, and like you said a lot of them may have it. What I don't want to do is order another and have it be worse. I just wondered if it was common and if those that can make it out in everyday use are going to return it. With that said mine can't be too bad as it isn't visible on any other color than black.

I would keep it sounds like minor light bleeding for you. It's normal to have some light bleed anyways. I've had it on all my devices (IconiaA500, Galaxy tab 10.1, Prime, Infinity, Note 10.1). If its visible for me even during the day then it would bother me and I would replace it.

It is visible during the day with auto brightness on, but it's only because of the black bar along the bottom. It is only just visible in lowish light with auto brightness on, so I don't know if I should send it back. The only thing I don't want to do is send it back and get one that has it worse.
First of all, I love this tablet. The only complaint that I have is that compared to my 2 previous 2012 Nexus 7s (now sold) and my Nexus 4, the new Nexus 7 I just received yesterday has a rather different color temperature. Whites aren't white -- instead, it has a yellowish tint to it.
Are any of you guys experiencing this, or is this just an LCD panel lottery that I lost? I'm wondering if I should swap this one out at Staples, return it and wait for the next batch, or if this is a normal characteristic of the JDI panels used in the 2013 Nexus 7?
This is really confusing to me, because in the AnandTech mini review, the 2013 Nexus 7's white point average is 6940K while the original Nexus 7's is 6215K. So my new tablet should have a cooler/more blue color than my old one, but instead it's the opposite and looks warmer/yellow.
mine is like yours so I just think its that way but I prefer it actually
I'm seeing a lot of green wash into whites/browns with mine, and poor black levels (too bright.)
The effect is more pronounced if there's a lot of green in a photo to start with.
I've posted photos comparing what I'm seeing on this device with what I see on a Note 8 in some of the other forum threads on this device.

That gives me hope that not all the displays used in the 2013s look like this. I ordered this one online from Staples, so I haven't seen another 2013 in person yet. I guess I'll head to Staples and Best Buy and look at the demo units and compare them to mine.
Edit:
Reading the other threads make me nervous about exchanging it now. This one has no dust under the screen, no dead pixels, no random reboots, the wireless charging works fine, etc. Aside from the yellowish screen, it's perfect.
I've seen what you guys are talking about with different Nexus 10s side by side. Had one where white looks like snow and two others beside it piss yellow looking white. I wonder if that's due to sourcing the display from different companies. My 2013 N7 arrives tomorrow so I hope it's not funky.
Just bought mine from my local Best Buy tonight. My screen looks perfectly fine. Also, no random reboots(was on it 4 hours straight), and no dust under the screen. I'll check it out again in the morning, but keeping my fingers crossed that mine is good! I didn't even know there were any issues with them until reading this thread
SwiftKey'ed from my White Sprint Note 2 using XDA Premium
Displays ARE different.
Get over it, guys.
With the Sony Xperia Tablet Z, many people also always complain about the display being too yellowish.
Some displays are too bluish, some have a reddish tint (like my prev-gen N7), some greenish (my SGS2), some yellowish (my Tablet Z).
That's how it is. Some people will shout: "But my Samsung has perfect white", bla... But this isn't true, either. Most probably their display will have blue tint, but they are accustomed to it.
If you want perfect colors, you have to buy Apple, and even then you can't be sure.
And now enjoy your Nexus 7,damnit!
I actually have a good screen, no reboots, (haven't tested wireless charging, probably should) but I'm not actually experiencing the yellowish tint. Try to download Dead Pixel Test by Ossibus Software from Google Play (only a 64kb app), launch it, then tap once to get to "pure" white. Post a picture (not a screenshot) of the tablet at that point.
EDIT: I've noticed that the xda app does have a yellow tint, but doing the dead pixel test reveals a pure white. This could just be xda.

yes, its a lottery. i compared 4 units now, all had different (from bad to worse) whites and contrast setting that effect the scroll blur, overall sharpness and black levels. there's definitely green push somewhere that comes of as yellow tinted screen overall depending on other settings of that particular screen or page you're viewing etc. keep on exchanging or wait for kernels with color control if they ever come that is.

Well, I've got an HTC Desire, and after every reboot, the display gets horribly yellow. Though, turning screen off and on resolves it. Thing is, displays differ from device to device. A friend has a SGS3 with overly cold display, the kind that made my eyse stare at it all the time
Then I look back at my Desire, and it looks yellow. But it goes off after a little time(the yellowish look).
What you should try is to lookat your N7 for longer periods of time, and you'll get accustomed to it
Perfect whites here.
Just wait. Custom kernels will allow you to adjust all of this. With my nexus 4 the colors were not ideal for me, flashed a kernel and choose from the many options of color settings. There will be something for everyone, no matter what colors you prefer.

we don't know that yet. nexus 4 color adjustments on kernel level were possible due to the exposed color controls. somebody needs to confirm if it's even an option with this device.

Definitely different white than my original Nexus 7. First thing I did was open Kindle in both, because I wanted to compare font sharpness, and I was struck by 2013 Nexus 7 looking yellowish compared to original, and thought I much preferred the softer look of the white on the original. Now, however, after using the new 2013 model for 2 days, when I compare the two, the new one seems white and the old one seems pinkish! So I think perception changes with use and familiarity.
I had far more noticeable white balance issues with Galaxy S3, and there was also a noticeable difference in white balance between Galaxy Note GT-N7000 and the AT&T LTE version.

I can't get used to it -- I have really low tolerance for this stuff. Especially since my Nexus 4 screen has good whites, and I'm sometimes switching back and forth between the devices. Or the 3 monitors on my desk that have excellent whites. It's too jarring.

Thinking back, my very first Nexus 4 had very pure whites. My current Nexus 4 is more yellow than that the first one. So for the Nexus 7 to appear yellow to my Nexus 4, it's got to be really bad.
Just to give an update...
I decided to order one from Amazon yesterday instead of exchanging the Staples one. I figured that buying from a different retailer would increase my chances of getting a different batch.
The old one from Staples was made in June 2013, while the new one from Amazon was made in July 2013.
Overall the screen looks much less yellow than my old one! So yes, LCD display lottery

so I don't think its a hardware defect more an software thing...
just to be sure i tested with an LCD/AMOLED screen tester app and when showing the black IT's ALL BLACK
I don't see any uneven tint in gray, white or any other color..... ONLY the yellow uneven tint on black background in settings, messaging...
I've had over 10 difference NOTE 3 in my hands trough work and the all had the same yellow tint

I notice it in the play store and chrome too...
I used to have a Galaxy Nexus which suffered from a yellow tint problem. I got several replacement units but they were all the same. My carrier refused to acknowledge it as a fault until a few months later when I saw a friend's Galaxy Nexus without the issue. I took a photo of the two phones side-by-side and sent it to my carrier. They finally admitted the problem and sent me a Galaxy Note 2 as a replacement phone.
I think that there are sometimes manufacturing issues with amoled screens. In my case, there was clearly an entire batch of phones with the problem.
The best thing to do is to go to a retailer (not the same retailer where you bought yours) and ask them nicely to show you a Galaxy Note 3 so you can compare the quality of the screen. Take a digital camera with you and if the units are different, take a photo of them side-by-side. Sent the photo to the retailer you got your phone from, or to Samsung (assuming you haven't tripped the Knox flag and if you have you might be covered anyway if you're in the EU) and ask for a replacement from a different batch.

Just Remove the phone from Power Saving Mode - The Yellow tint will go away
