Have any of you (Nexus 7 owners) experiences an uneven color temp/brightness across a Nexus 7 screen? I have searched threads in google but found no Nexus 7 owner mentioned about this but many iPad owners did.
My Nexus 7 is a C9O which was replaced a screen by ASUS 1 week ago (due to broken screen). I have noticed this problem 2 days after received it back. My screen is generally a "warm tint" (as most N7 are, I believe) but when I see a white or grey background (in ebooks or webpages) in portrait mode, about 1/3 of the left screen has a more cooler tone and it is gradually warmer toward the right. There is hardly noticeable when I watch movie or surfing most websites but it's quite annoying when I read e-newspaper or ebooks which are around 70% of my usage.
Note that this is not due to viewing angles since I tried to rotate the screen / change viewing angle and the problem is persist (on the "correct" side). I tried to use my DSLR to take a shot of my screen but it can't capture the uneven color temp just like eyes do.
I just want to know if this is normal for an IPS/LCD screen? Please share your idea / experience on this. Any way to fix it?
P.S. I am not an English speaker, really sorry for my bad English.
Just had my UK Note III delivered, and initially was blown away with the screen..
But when the evening came, and the lights dimmed, the screen auto brightness kicked in, and I've noticed some website backgrounds which are lighter shades of grey seem to show a slight cream tinge mainly around the middle of the screen..
I don't know if I'm being too fussy, the screen does seem 'warm' around the middle as well, it's much cooler at the bottom of the screen, where it seems to have no tint at all..
What's everyone else's like..

I just stumbled upon this thread. I have a similar problem and created a thread last night and included a picture.
Did you end up keeping yours or exchanging it?
Thanks!
I exchanged it, but the new phone was not perfect either. I then tried a few galaxy oled phones, like the note 2 and s4, plus a couple of note 3's in the shops, and they all don't have pure whites at lower light levels.
So, I've decided to just keep this, and very used to it. The large screen doesn't help, as viewing angles mean up close never looks perfectly uniform, so it seems a feature of Sammy screens.
The phone is just to awesome for me to get hung up over it. . Most people cannot see these things, and was surprised to see all 5 S4's I got my hands on looked identical, just slightly reduced due to the screen size.

There seem to be quite a few Note 4's being sold globally that suffer from serious screen coloring (color shifting) when watched from close to a normal viewing angle. To get an idea of the scale of this problem this topic contains a Poll.
This defect is most easily noted on a bright white screen (www.google.com, "Dead Pixel Test" app). Even at a slight angle (=20"-30" from dead straight) the screen will show a clear blue, green or red colored haze. The screen on a properly built Note 4 stays (close to) white, even at a wide angle.
Please let us know if your Note 4 suffers from this phenomena beyond a trivial degree or if it doesn't.
Also be aware to check for this defect BEFORE you root your Note 4, as Samsung will object or even prohibit you to exchange your device for a better model.

Thanks for the link! Was just going to add it in the opening post, but this also seems adequate.

I don't think there is such a thing as a "normal" Note 4. Every AMOLED phone from Samsung varies from unit to unit. I remember finding exactly the same differences between two Galaxy S3s where one had a tint horizontally and the other had a tint when angled vertically. Interestingly the phones with the greatest colour shift are usually the ones that go brightest when looked straight on. Either Samsung is making these phones in multiple ways from multiple factory plants....or for whatever reason using different materials (such as polarising materials) in the top layers of the screen.
Although I didn't check the tint on a second Note 4 I tried, I did notice that mine was obviously brighter at all points on the brightness settngs bar!
Either way, while bad uniformity is definitely a defect....I think this off-axis viewing tint is not. If it was a defect, it would exist with Note 4 only and not all the Samsung phones I have seen to-date. BTW my Note 3 also tints when viewing at an angle but a bit less than the Note 4.

I never had this phenomena with my 5 previous Note or Galaxy S phones, nor on my Samsung Tab S 10.5's. I did have multitouch issues on my Note 3 and 2014 Note 10.1. Seeing the screen of the Note 4 is plenty bright I don't care too much for the "more brightness" bonus, if it were applicable here. I compared my unit to a random store unit and in direct comparison I much preferred the store model. The white screen already looked a bit 'off' on mine, and the store model did not have color shifting at all.

What are the chances of both my Note 3 and Note 4 having the same "fault" though? My Note 3 goes bluish off axis, my note 4 goes greenish. Both screens are still perfectly readable at any angle, and only colours that noticeably shift are white/grey. Orange still looks like orange, red still looks like red.

I think it depends on the amount of color shift. My Note 4 has a clear blue haze even when looking at it close to dead straight. I watched a snowboard movie/documentary and snow went definitely blue with only a shift of 20-30 degrees.
It's really good news to know that many devices don't have the blue tint when shifting! If mine has it I'll definitely send it to maintenance. I guess repairing is better as I can look at the device at their facility and not accept it if I don't like the results.

It is really hard to be sure we are all seeing or evaluating this the same way. For example, if I display a photo with many colours, I see no shift at any angle. White is the most obvious and you need "lots" of it like a www.google.com screen to see it. I would say I am fine for 20-30 degrees before it starts shifting. I think you may have been a bit unlucky in happening to choose a snowboard documentary rather than Iron Man 3 or something like that etc! Then you might not have noticed it
I voted "No" because the poll asks whether the screen color changes at a "SLIGHT" angle. While mine does not, at a larger angle the screen does show blue tinge that increases with the angle.
I have this too, its normal?
I have the same "issue" actually it was the first thing I realized when I turned on the phone for the first time. I haven't even realized it with my previous used galaxy S5
It's probably caused by some coating layer. Nothing we can do about it, doesn't distract me much in a phone anyway. The screen is lovely apart from that, the black level made me almost cry when I compared it to my LCD TV. I so want an OLED TV now. Shame they are so expensive.
Mine does this:

Is this a faulty display or is it just the way this display works?
There are several factors involved,
- Amount of Oleophobic Coating which distorts the actual colors discernible by the viewer
- The Digitizer
- The Corning Gorilla Glass
- And the amount of bonding used to keep the AMOLED display adhered to its bottom layer (Remember: Organic by Nature).

I get all the colors green a little blue and a little red it actually seems to me like a [email protected] rainbow I don't mind it much because it doesn't distract me much but I will pay more attention in the near future before buying a Samsung phone again...
No solution to this feature?

It is not repearable by software or external means. Well, maybe a heater could do something, but I am not gonna try.
I sold my Note 4 and now have the Note Edge, which luckily has much less issue with color shifting.
While looking directly mine is red at the middle of the screen. While rotating, the red tint is appearing at the top or bottom of the screen according the rotating direction. Also Bottom part of the screen is also less white than top.
Forgive my not reading the entire thread as it's late and time is an unusually precious commodity lately...
My screen does develop an extremely mild hint of a color shift at slight angles, but I don't notice it unless I look for it. However, at extreme angles (at which I never view the screen, like greater than 75 degrees away from dead-on perpendicular to the screen surface) I do see not only greenish/bluish (almost like a faded teal) but also a magentaish hue. I suspect in my case it's a result of the manufacturing and tempering processes of the glass. LCD panels exhibit something similar when viewed through polarized sunglass lenses, but this is not the same: LCD panels have a nearly random-blob appearance where on this Note 4 it appears in bands running along the vertical (when viewed in portrait orientation) axis of the screen. At worst, I can make it greenish on the left side and magentaish on the right by viewing at around 70-80 degrees off perpendicular, so admittedly I have to hold the phone in such an extreme position to see this that I don't consider it a defect per se.
HIH.
I have the note 3 n900 and i notice that the white color on the screen has an obvious yellow tint so i compare it with galaxy tab 2 10 inch and galaxy mega 5.8 inch ... and both devices shows the white color like a normal white not having this yellow tent on white color like my note 3 and the white color is more bright than my note 3 ... and i set the screen mod to dynamic mod cause its the least yellow tint of all other mods like standard or even adaptive mod.. so i don't know ... is it only my device or all note 3 devices are like that and do u compare its screen it with other samsung devicrs

I had a Galaxy S2, had yellowish tint on the display. I am unsure whether it had two variants or not, but I had the one which was officially sold in my country.
I had a Note 2, Exynos, yellowish tint was there but in less extent.
I had an S4, Exynos, there was almost no yellowish tint, at least that's what I can remember.
Now I have a Note 3, I don't have any yellowish tint at all, and I use movie mode. Turning on Adapt display or Dynamic makes the screen irritatingly cool/bluish. Honestly I could not be more happy with a phone's colour reproduction.
However I read a lot, and I saw that a lot of people possessing the Exynos variant, which is yours, are having this problem on GSMArena Note 3 page. You can see for yourself, just go back few pages. I think it has something to do with Exynos models only? Cause I have never heard a person having a Snapdragon variant complaining about this issue.
You can ask Samsung CC to replace the phone, only if you can show them how a display without any tint looks like, cause they are both arrogant and dumb.
Thanks 4 ur reply

Keep in mind that the Tab and Mega are LCD, not AMOLED. LCD has a pale blue hue, whereas AMOLED is much, much more saturated.
You really should compare it to another N900 unit, or an N9005.
As mentioned above, this is a problem that occurs on the Exynos version, but not the Snapdragon.

Hey guys I buy s4 (deep black) version from amazon India. I have this from last 2.5 months. Recently I noticed screen ghoshing/ seamring issue on my s4 display. Frankly speaking I never ever noticed my display to much but after only reading this issue on web I do notice.
Issue is like when you scrolling ur screen on black background or black font on white background, the black color produced some purplish and red color waves. This is 3 min video on this issue :-
http://m.youtube.com/watch?v=DOQ91ujRFxU
So tell if this issue exist on your s4, then i dont go to service centre for repair my new grt device...otherwise i don't go. Thank you.
