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
Ever since I got my Xperia M the display has had blueish tint and bad color reproduction but I acknowledged that is a problem with every Xperia M. But beside that, when I look at the display from an angle, on a white background, I can see a gray line appearing from top of the screen and a gray circle in the middle. Again, it is visible as an effect when looking at an angle, cannot see it when looking directly at it. I also have a bright pixel on a black background. Are these also negligible, common issues or along already bad screen I've got a defected screen? I am very disappointed in Sony anyhow.

I'm pretty sure I saw this post somewhere b4... anyway for bluish tint - get the white balance app from @xperiaz2 (Yes, you need root and the bluish tint is due to the colour temperature, its at around 10k+, the norm. being around 6500k) Gray line appearing... pretty sure you're having a defected display and about the bright pixel, display is defected. Yes you got a defected screen (The bluish tint is not a defect though) so just bring it back to where you bought it and they'll replace it for you! (If the warranty is still live)
Well I posted on Xperia support forum trying to get help there, too. Or just an insight of what could that be and what could cause the problem. Anyway, here are a couple of pictures taken with a phone. The camera couldn't get that grey line properly but it appeared as a shadow from the top of the screen probably because as I said it's like an effect when tilting the phone, not a still colour. http://imgur.com/3Ae2rdr http://imgur.com/Nyv2maS
I suggest you to bring it back to the shop, that problem isn't present on mine.
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.

I though i had ocd with phones but that just doesnt bother me in the slightest. Cant really tell unless you force yourself

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.
My moto 360 seems to have a grey ish patch above the bezel which is visible on a white background when the watch screen is dim. I'm wondering if it's a defect or if other people have the same thing - here are the best pictures I could get: http://i.imgur.com/qYIo84F.jpg [1]
http://imgur.com/qYIo84F,rTPm5jY#1 [2]
Look just below "Sun 9" and above the bezel, and the white looks muddier, almost grey. It's more noticeable in person. It's always like that on a dim brightness, when the brightness is high it looks perfectly white.
Do other people have this too?
I believe I have a very very small spot kind of like yours. They are typically caused by uneven pressure on the LCD screen. If mine has a spot like that it is just above the flat tire, I can't always see it and nobody else can. I have no stuck or dead pixels so it doesn't really bother me.
Hi all,
Had my Pixel for a few days now and noticed what I thought was a new gradient in the background of posts in the XDA labs app, I checked the screen using one of the grey test colours and found that I'm getting a dark cloud over the bottom right hand side of my screen. I tried taking a photo with my old phone (Moto X Pure) but the camera isn't good enough at low light for it to show up, I'll try and get a photo with my DSLR when I'm back from work later today. In the mean time some quick googling has shown it's very similar to the "Dirty Screen Effect" described here: http://www.rtings.com/tv/tests/picture-quality/gray-uniformity-dirty-screen-effect-dse
Had anyone else noticed this? Do you think Google would RMA it? I've not really been bothered by the blue shift on my device so I'm slightly concerned that I might end up with a worse replacement if I do send it back
Cheers
Michael
It's a tough call, you have to ask yourself if you can live with it or not. Does it show up a lot during normal usage? Or is it just with the XDA labs app and similar applications in a low light setting with your brightness turned to like 0-10%? Or if you can see it at all times regardless of brightness settings you can contact Google tell them of the screen issue and get a RMA. Check out the replacement and compare the blue shift to your current and see if it also has the same issue as your current device. If it's better in both regards send it back, if the blue shift is a bit worse on the one and you can tolerate it and it doesn't have the bad back light uniformity you could keep it. That's what I would do personally, best of luck!
Yes, I have a similar issue. My first device had severe blue tint at any angle and Google would not replace so I returned and and reordered. The second device had only slight blue tint and is not an issue but of course has the uneven grays. The right side of the screen is much darker and there is also a dark spot around the sim tray area on the left side. I sent Google pictures and they are sending a replacement. It's only noticable in low light, looks fine at higher brightness though.
Ah I didn't realize they sent you the replacement first. That makes it a much easier decision. I'll still try and add a photo of it in the OP later today but RMA seems like the best choice. It's noticeable at lower backlight brightness and since it's winter here in the UK now the auto-brightness often drops it down to a level where it is noticeable just in normal daily use.
I get a VERY slight hint of that on a dark gray background at 5-7% brightness in a totally dark room but other than that very specific condition it's uniform otherwise.
The photo as promised unedited straight out of the camera (USB C OTG is neat). It's not quite this bad in person, if you imagine the light grey is the same shade as the dark grey in this image and the dark grey as being almost black then you get the idea, but it does show the difference between the two and it is clearly visible with the naked eye in a dark room.
