Hello
I found 3 blue big stuck pixels, 1 tiny white stuck pixel, and minor light bleeds with a significant but little leakage at the back button spot. All of these were found under dark room when displaying black. Unfortunately I got no camera good enough to shoot under the dark condition.
The tiny white stuck pixel is nearly invisible. About 2 to 3 pixels big.
Light bleed bothers me a bit but it is almost unrecognizable in a normal usage.
Blue stuck pixels are the weird ones (they too are invisible in normal usage). Even though they are relatively big, they can be only seen when displaying black. Cannot be seen in any other colors. What would these be?
Also I bought my nexus7 in the eBay. This means that I have to pay for shipping back if I want a refund. Also there is no guarantee that I am not getting a worse one.
Should I ask for an exchange or keep it?
Thanks

Hi there,
I just got my T-Mobile SGS2. When I look straight at the phone screen, I see whites that are yellowish, as if the color temperature is bumped up by +2000-3000K. Tilting the phone 5-10 degrees to the left or right shows proper, much colder whites, as one would expect. The same nice whites can be seen if I tilt 20-30 degrees up/down.
Perhaps I would not have noticed this problem had I not played the with international version of SGS2 - the whites on that phone are just stunning anyway you look at it. I went back to the T-Mobile store and all the SGS2 phones there the same "issue". The guy in the store thinks that is how the colors should be...
Am I going crazy here? Is it normal to see this yellow cast with a straight viewing angle? Can someone confirm that their screen shows fine whites at any viewing angle? I'm considering sending the phone back for replacement, but it'd be futile if this slight yellow cast is indeed normal...
Mine is like that too. I think its just a quality of the amoled screen, cause I've seen it on other amoled phones too. You get used to it.

I've checked out/toyed around with close to half a dozen handsets since they came out a couple weeks back and I have yet to see one that has a yellow tint. Every one I've seen has had a blue hue/tint, some approaching a grey cast while a couple others almost like a light mint green. Unfortunately AMOLED screens have the hardest time reproducing white as there apparently is no such thing as a true white LED.
Sounds like the one you got did indeed come a lot warmer than most which tend to me on the cooler side. I wish they would have a factory setting much like most flat panel TVs have for setting/adjusting color temperature to your liking. The blue tint really bugs me but I guess over time you just get used to it. Same would go with yellow too, just have to get used to it. I suppose you could keep exchanging phones as some lucky few out there seem to have gotten handsets with a good color temperature where whites actually look white, but who knows how many times you'd have to try that. I'd bet most places wouldn't be too willing to do that for a customer though.
I'm looking at a yellowish tinted XDA now. Totally dark in my room, auto backlight could be the issue...

I got my galaxy nexus this morning and I have to say, this screen is awful. I'm not sure if it's defective or they are all like this. Everything was fine until I turned the brightness down. I loaded google.com up and the white on the page looked like it had colored dots in it. It's not white at all. After looking at it for a while, it appears to be some type of image retention? Do these type of screens get burn in? When I flip to landscape the area where the 3 bottom buttons are is worse in discoloration and I can make out the button images. It's not too bad but this thing was $700 and plus it's only 12 hours old... I don't know if I should return it?
Spray neutrogena sunblock on the screen...make sure its spf 100+!! No more burn! Oh wait!...
Seriously, you may just have to exchange it.

Other people have reported image retention too. It's 'normal', unfortunately.
I got it to my plan is to just wait a few months/weeks and wait until batches with perfect screens will ship then I will return my phone. So I get hopefully one with perfect screen. Trying to get one with a good screen now looks like playing russian roulette.
Hello,
My screen yelleow tinte

You might want to take a look at that thread. It probably is not burn in, but perhaps color tint and banding. (At low brightness, the whites will seem grey and have a sort of linen look to them. Many screens have also red/green discoloration.)
Here are samples about the screen issues:

Long story short, get it exchanged - however, there is a high likelihood that the new unit will suffer from the same issues.
I exchanged mine and this one doesn't have blue streaks vertical lines or dots.

If you see vertical streaks in it, exchange it. My first GNex had some very noticeable streaks but my second one is fine. The 'linen' look on light backgrounds when the screen is very dim is going to be on all of them from what I can tell. That seems to be a quality of the SAMOLED screen used on the GNex. If it is uniform, then it's it no big deal and 'normal'. You should not have to put up with the vertical streaks, though.
Hello, I have trouble with my Nexus 7 2013. I have got new device a few days ago and I found dead/stuck pixel at the bottom left corner of my screen. For me it looks like dead/stuck pixel, but after several tests I am not sure.
I can see it only at max brightness (at lowest or medium it is almost invisible) and ONLY at black color.
If I will turn a little bit my device it changes color for green, red (at least I think it looks like red or green) etc.
I did several tests with that app: https://play.google.com/store/apps/details?id=com.htc.chris.blackspotdetect
And I cannot see that pixel in any of those colors built-in app, except on black color (it is clearly visible on black background).
My question is: is it dead or stuck or anything yet pixel?
Thanks for any help,
best regards

it could be a dead pixel, but my advice is to return and get it replaced while you can because later it may be half of your screen or worse!
And I will Thanks for pushing my mind forward, I was afraid of sending it for warranty, but I have no choice.
Isn't there a number of dead pixels there has to be before you can send it to warranty/exchange it?
Hey everyone,
I got my black AT&T Note 4 earlier today. I noticed the lower half of the screen is slightly darker, and has a slight pinkish tint on a white screen.
I do notice it in some apps, like Kindle when readinga book. Top of screen is slightly brighter, and when background is white there's a very slight pink tint.
Is that normal? Or should brightness be uniform and no tint?
EDIT: I added a photo. It's not a good photo but you can see how one side is tinted differently. In the photo the brighter top looks greenish but in real life it's not green. You can also the slight pinkish tint in the bottom half, which is the left side of the photo.
I wouldn't want to comment based on the image you uploaded directly since how a camera captures a digital display is much different than what the naked eye will see. If the picture on the panel is not consistent and appears polarized in any way, I would consider that to be faulty. Get it replaced.
Galaxy Note 4 (pink tint lower screen)
Hi there,
I have also noticed a pink tint on the lower half of the screen on new Samsung Galaxy Note 4.
As i intend to do a lot of drawing on this device the tint is unacceptable.
I wonder if there is a way to calibrate the display?
I had this issue with my Galaxy S3 display. I had at&t exchange it.
Have this same issue on my Note 4. Posted some pics over in the thread on this topic for the Note 3 before I thought to check here. Basically there's a brightness and gamma gradient from top to bottom. The top half is perfect and the bottom half gradually fades to a point where you lose the first 8-9 squares on the lagom.nl black level test.
This one emphasizes the black crush, which can be visible in video content on a dark screen (and makes dark colored backgrounds fade to black towards the bottom):
And here's one on a white background. At first it seems like a white point issue (which I would tolerate since it's common on IPS as well), but it's a brightness gradient:
Between this and the fact that AT&T disabled the slider for auto brightness I'm a little frustrated with this supposed best smartphone display ever (I realize this second issue isn't Samsung's fault, but the auto brightness is unusable without that feature). I bought the phone at Best Buy which is mostly out of stock right now so an exchange isn't likely, assuming they even take this seriously as an issue.
My note 4 does not display this issue.
No issues here. Display looks very consistent.

Have you tried a dark background in a dark room? For me it wasn't that obvious until I did this (was messing around in Sketchbook). If the majority of screens are better than mine I'll definitely be trying to get a replacement as this is bothering me.
I just installed Lux to resolve my backlight issue and its settings menu background fades nearly entirely to black at the bottom.
*Edit: So far it sounds like this is an anomaly. You would expect places like Anandtech to report on it if they'd seen that amount of variation. I'm going to have a good time trying to convince someone at BB that this is a real defect though.
Erica Griffin talks about this issue in her Note 4 review, around the 20 min mark: https://www.youtube.com/watch?v=-OyNWrQJzMY
I got a replacement and it's perfect. No pink tint.
So, if you have the tint return it. Not all Note 4s are like that.

Thanks, that was quite helpful. I think in general it's easier to trust reviews on retail-purchased devices over mainstream reviews with PR department selected units.
I went to BB today and looked at the display units. All perfect, but then that's not surprising (every company gives their display/review units a second QC pass, even Apple). I'll probably head to the only BB in the area that has units tomorrow and see if I can do an exchange. As long as they don't make me sign one of those "no more returns" agreements I've heard about I'm willing to take another shot in the display lottery.

Good to hear! I'll post my results after my exchange attempt tomorrow. Aside from the gradient I am impressed with the display. Not as bright as LCD in daylight, but I was drawing on a black BG last night and noticed that it has deeper blacks than my Pioneer plasma.

Fingers crossed for you to get a nice one like mine.
Yeah, the blacks and colors are amazing on the Note 4. The whites are not as bright as the iPhone 6+, but they are fine and way better than whites on my Note 2. In all other respects the Note 4 screen is overall better than even iPhone 6+'s excellent LCD.
One minor disappointment is the very high resolution has made some emulators dog slow as they attempt to render at full resolution, i.e. PPSSPP and ePSXe using ogle renderer. Hoping the devs find a workaround, maybe rendering at half or quarter rest instead - that would still be higher rest than my Note 2 at full rest. :laugh:
What's the color of your device? Anyone have this problem in the white version?
my note 4 has pink tint
I have the same problem on my Verizon white note 4 but on top half of display. Replacement should arrive by Friday :/
You can replicate this by looking at the screen at an extreme angle, obviously the ones that see green and purple straight on are screen defects.
I have a white version and whites are perfect and too bright at high setting. I keep mine half way. The whites are better IMHO than the iphones. The colors more vibrant and, the sharpness is ridiculously sharp. I dont see how they can improve it. I only thing there should be a waynto adjust the color saturation, because basic mode doesnt do much on mine.
My Note 4 has the same issue. It almost looks like the while balance differs from top to bottom, but it is really the brightness that is different.
This is a photo of my Note 4 showing a solid colored image at #030303 (very close to black). It shows how different the pixels in the bottom and in the top emit light.
Image can be seen at 1x.com/tmp/uniformity_note4.jpg
Looks like crap.

similar problem
I have a similar issue, though mine is brighter on the right side than it is on the left. Very noticeable with dark background in lower light situations as someone else mentioned.
hey guys,
I received my OP3 on friday and it has very unequal light emission. in the middle of the screen there is an approx. 1 centimeter thick line which is darker. it is only recognizable at dark colors like grey blue etc.
Does anybody have the same issue with the screen?
is this normal or should I send it back?
Thanks
pics below (in real it is way more darker)

Pretty sure I don't have this - if I do it's too subtle to notice.
It's quite clear on your one, so it looks like an actual issue.
Send it back to the company.
