OK so I have in front of me a novatec and epson unit.
I need to choose which one to keep and it is killin' me, for several reasons.
Off the bat. Pro's of both.
Novatec:
Looks better/more vibrant.
Brighter.
Changing brightness always fades in and out. (Noticeable from power control, screen timeout, and brightness control in the settings menu)
Epson:
More realistic.
White's and black's look better.
Problems. They both have light leakage (same amount).
However, the novatec has a stuck pixel which is why I got a replacement, also, though it looks better the coloration is very slightly off (strange, almost pinkish hue on white's).
Epson sometimes shows horizontal lines upon close inspection (especially on grays) where the novatec doesnt. Also looks slightly washed out..
The last problem that is really bothering me.. It doesn't fade in/out lol!
I know it sounds stupid, but why would a different LCD change something like that? Which is clearly software.
Is there any way to bring that back?
It just seems like a really stupid thing to disable a feature that is clearly aesthetic for only the epson's.
I found one reason why the immediate brightness change is beneficial.
When you turn off a nova and turn it on, for a second it's at max brightness then ramps down to the set brightness.
Epson is immediate .
I think that is why they chose that method.
I'm still stuck here.. I want the higher quality screen, but i get mixed reviews from the web.
Most people think that the novatec looks better, but is less accurate.
I would have to agree with that.
So then which one is higher quality?
I would like some background on Novatec/k/ch. I cant find much about them other than this website.
www.novatech.co.uk
At least for epson I have heard of them before and they are known for their imaging products.
The only time you will notice a difference is when you have two in front of you.
Or you obsess about it enough to research it to much and create a post on a forum about it.
I have a Novatec and I am glad I do. I don't like the look of the epsons that I have seen. And mine fades nicely.
I'm a huge fan of my Nova. I've seen both versions, and I much prefer the Nova's.
One thing I did notice between the two though: on my Nova, I can see vertical yellowish/off-white lines on pure white screens. Look closely, you'll see it too most likely. Bugs the sh*t outta me
But on the Epsons, I also saw the horizontal greyish lines the OP mentioned.
Just my $.02
So keep a nova with a stuck sub-pixel (only noticed it on blue), or an epson with an otherwise flawless display.
Last option is to complain and have them ship another one and hope it's a nova.
Why can't I have the whites of an epson with a nova screen! DAMNIT
Side by side with my friend's Evo. Nova vs Epson, and I had a hard time seeing a difference as far as brightness and color. I really didn't take much time to compare the two however.
It seems like the entire spectrum of color is shifted slightly warmer for the novas.
The Epsons are probably better since the spectrum is baseline and more accurate.
Pure white #FFF is perfectly white on the Epson.
On the nova its warmer, slightly yellow but that gives everything a more vibrant/colorful appearance..
All I need know now is that epsons are reliable and high quality lcd's
I just got an Epic.
Reading several threads across the Galaxy line, there is apparently a variation in screen color temperatures. From my readings, I see a pattern where perhaps the newer/replacement units have yellower screens. At the same time, those newer units also get darker in auto brightness mode than the older units.
From my own observation, the color temp gets cooler as the brightness increases.
Is it possible that Samsung tweaked the auto brightness so that the phone now gets darker in order to save the battery? So perhaps the different color temp observed are a function of how bright the screen is?
I don't care for the yellowish screen on my new Epic. I like a cooler/colder screen. Comparing the Epic next to my LCD Evo and Touch Pro 2, it is outright yellow. Comparing the 3 phones next to my Nexus One, the N1's screen looks pink. (I can post some pics tomorrow).
Bottom line, I'm trying to decide if I should try to return/exchange the phone for another and hope for the best. I read that there are some potential software solutions out of XDA, but I prefer to have a phone that is natively "cold".
Any input would be great.
Thanks.
Mine's pretty yellow. :-( In brighter light, it is not a problem. Darker screen is the result of a software update. Got mine on launch day.

Thanks for the information. Before the software update, when the screen didn't get as dark, did it appear less yellow at the [pre-update] low brightness?
In other words, does the screen now look more yellow than ever since the update and darker screen?
Cheers.
I got my Epic on Oct 1st, and I haven't noticed this yellowish at all, but maybe I need to do a thorough side by side with an older model?
Did you get any pics to post up yet? I'm interested to see this
Edit: Sorry, just saw you said you can't post pics until tomorrow.

Just as yellow as always. Post-update, the screen dims more. At this point, it appears yellower. My Captivate also now dims more, post-update, and seems bluer at dimmest setting.

The only time I've had problems with my screen was when my phone had gotten damage from water. I'm on my 2nd epic and this one doesn't have any yellowish tints. Only about a week old now.

I picked up my Epic on 9/29 and don't see any yellow tint at all. I'm not an expert here but I think I would notice a tint like that. My blacks are very clear and dark also. I did notice that it seemed to run on auto brightness a little darker than it had...that was probably the D-118 update after I had it for only a few days.
I will follow this thread and see where it goes.
I don't think the screen color variation is based on release date. I have two of them since 8/30. One of them has a yellowish tint compared to the other. They both have the same DI18 update.
It seems like a coin-toss what screen color comes. I wish we have a tool that would allow easy color temperature adjustment.
I read a thread about a way using a modified kernel, but it would be nice to have an .apk that works (even if it requires root).
I got one on launch day that had more of a blue tint to it. I got another one last week that was a refurb, and it definitely is more yellow.
Weird. I just got mine today and it's very cool (read: blue) compared to my Evo... being a photo guy, this drives me nuts. I prefer warmer diplays.

I have one of the cooler screens, and I kinda like it.
My thoughts:
1) Samsung is trying to extend the life of the blue oLEDs by altering the color temperature of screens. Since this seems to be happening independently of ROM version, it's probably something they're doing with firmware.
2) (IMO More Likely) The screens on different phones came from different assembly lines or different production runs, and have a slight variance in color production. The production date of the phone wouldn't necessarily matter in this case.
The only project I know that deals with the color temperature of the screen is voodoo:
http://project-voodoo.org/color
I currently have it running on my ROM. It adds a new "very low" brightness setting a the bottom that's much dimmer than even the lowest one available in DI18. (Note: it doesn't interpolate levels between them, either. Meaning there is a big jump in brightness from the voodoo lowest level to the DI18 lowest level, which is the next "notch" up on the slider.) It also adds a brightness level at the very highest brightness, which noticeably makes the display warmer. (The highest and next-to-highest brightness notches are the same brightness, the difference being the highest one is warmer.) At this point of its development, it's really of no use if you want to make your screen warmer at all brightness levels.
At any rate, the project leads me to believe that, with further development, we could have an app that allows us to freely change all the color settings for the display for all brightness levels, save them to profiles, etc.
The idea of the screen getting warmer as you decrease its brightness might be a natural phenomena, or just perceptual. In my experience, colors usually seem warmer as you decrease the intensity of the light. This is even true of light on a physical object.
My screen looks awesome. No yellowing or anything. I wonder if there is a difference based on who made the screen for that particular Galaxy S phone? I remember reading an article when all the Galaxy S phones started rolling out saying that Samsung was having trouble with the manufacturing of the AMOLED screens. Perhaps they started cutting corners.
However, there also seems to be issues with auto-brightness, etc...I have that disabled on my phone and the brightness set on its lowest setting (which is plenty bright for me and all my viewing needs) which may be the difference? But, I have cranked it up from time to time just to show others and I still don't notice any yellowing.
Is there a specific test image or something where one could view that would show/exaggerate the effect people are talking about? I would be curious to see...
Thanks for the great input and information.

Here is a quick picture taken by a Touch Pro 1. Sorry about the quality. I can try to take better ones if there is interest.
From left to right - Evo, Epic, Nexus 1, Touch Pro 2. All with auto-brightness on.
In real life:
The Evo looks whiter (cooler)
The Epic looks much yellower (warmer, almost greenish)
The N1 doesn't look as pink as it appears, but looks the darkest
The Touch Pro 2 looks the whitest (coolest)
To my eyes, the Evo/Touch Pro 2 looks good. Although the picture shows the Epic looking pleasant and only slightly warmer, the white elements (clouds in wallpaper, browser backgrounds etc.) look yellow/green.
Edit: Notice the Menu, Home, Back, Search menu LEDs look whiter than the screen. See the contrast between the two makes the screen look yellower.
I've owned 3 Epics since launch day. First one had a good screen, 2nd one had a yellow tint, 3rd was perfect.
The build dates of the first 2 were 10.08 and my current one is 10.09.

By perfect, do you mean that it is not yellowish? It's interesting that the first two phones with the same build date has two different color screens...
The Epic I have has a 10.10 build date. It's yellow at dimmed levels and color temp gets cooler as it brightens up.
So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.
Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.
I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.
I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.
Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.
Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.
I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)
You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!

So there is a slight pink hue in the right side of the screen. I was wondering if most 6Ps were like this, or is it a defect. I did research and found that many ppl have this issue, so maybe its just how the phone is?

If it annoys you then it probably is worth an RMA. This is a symptom of the manufacturing process with AMOLED screens, so they will all have it, some not as much, some much worse. So going for an RMA is a bit of a gamble because you don't know whether your replacement will be better or worse.

I wonder if the new Gold 6PS with the newer build dates have better chances at a uniform screen
I've seen two devices, both January build dates. One was pink across the right side, about 1/2" of noticeable area down the length of the screen. The one I currently have is less pink, but on the entire left half of the screen. It's only noticeable because the right side is more of the greenish blue typical of AMOLED whites. It's only really noticeable in dim ambient lighting, with lower brightness, on white screens (such as browsing), but only when I'm looking at the display for extended periods and trying to notice it. I just picked my phone up right now and opened Messenger, but didn't see any of the pink tint at all unless I kept staring and tried to make out a difference.
It's subjective and up to you. I wish we could all get perfect screens. But it's only visible on white content... anything else you shouldn't notice it. I just hate hearing people RMA'ing 10 times because it certainly isn't good for Google or Huawei. It's the nature of the beast with AMOLED tech currently. Unless you have something crazy bad with your display, I feel like most people are making it a larger issue than it needs to be. If you want a perfect uniform white, go get an LCD and enjoy backlight bleed, poor contrast, etc. Until AMOLED gets perfected, there is going to be a potential, but slight, trade off.

I agree with your point, but unfortunately in the case of the 6P I had to RMA for other reasons too. My volume rocker warped inwards, as so has many other people reporting on XDA and reddit threads. I am not sure how it happened, as I baby my phones and keep them well taken care of. I just took my case off one day and noticed it. There must be something wrong with the structural integrity of the device. Other than these 2 issues, the phone is perfect for me, but I am hesitant on ordering another one now.
On my second 6P the lower part of the screen has a yellowish tint while the upper seems more pinkish/warmer. My first 6P which was this year's build had a uniform but pinkish display loose rattling buttons and imbalanced speakers and bonus low volume output from 3.5 jack. The replacement had all those issues resolved except from the screen which is not uniform and it's noticeable. Problem is no Google and easy RMA process in my country. It's pain in arse to get a replacement and you have to wait up to 1 week without a device to get it and they will not repeat it for second time except if the issue is really serious. By my experience this phone has really cheap QC issues. Judging from reddit and XDA most come with some sort of problems. Be it it uneven displays, buttons, reboots, speakers etc. I won't buy a Huawei device ever again. Those issues does not let me enjoy this phone as I should. I still love it but I can't recommend it to any of my friends due to the QC issues. It's a Russian roulette with very high probability to lose.

I agree on the QC issues, I won't be buying Huawei again either.
At the moment, I have both devices. Having used the S7 Edge since the release, yesterday I switched to the S7. In shifting back to the S7 Edge just now, I noticed the two device's displays are quite different.
The S7 clearly has more saturated colors and looks far brighter. The S7 Edge, in comparison, looks slightly more dull when side by side.
For reference, I tested both devices in the same conditions. That is to say the S7 and S7 Edge with automatic brightness disabled and pushed up to maximum manual brightness. Also I tested both in a darker room. For reference both were set to AMOLED Cinema.
Unfortunately even when the automatic brightness is turned back on, it's clear the S7 still looks more vibrant.
Can anyone explain what's going on here? Is it simply that the Edge looks like it has a lesser screen because of the larger size and thereby lower pixel density. Or is it something about the panels themselves and thus the S7 that I have now just happened to get a better panel than the Edge.
Any thoughts or answers would be appreciated.
Displaymate tested them and stated that they are practically identical in terms of performance: http://www.displaymate.com/Galaxy_S7_ShootOut_1.htm. Any chance you can test out against another Edge?

Actually no, unfortunately. Neither device has been released in Japan yet. Both of the ones I have are imported.
The thing is lot more complicated...
Each S7 Edge has different display quality! When you put 2 S7 Edge Side by Side and compare, you will see that the displays have different tint (mostly yellow), and more worse: a lot of the displays are not homogeneous. that means that one corner or side is brighter then the rest of the display.
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
basically i do think that the s7 screen is better, due to the Edge screen is P-AMOLED to be flexible! but the differences between otherwise identical devices are really huge!
i ordered my 5th device today, because all of them had flaws:
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!
The s7 has more PPI due to smaller screen than edge

Or, you know, maybe you're looking for a flaw that's not there? It's a well known fact by now that a bend in a display, like the Edge, will have some shifts in brightness, tint and contrast, especially right in that bend! If this is something that annoys you, then I'd recommend you stick with flat panels from now on, because this won't be "fixed" for awhile. It's just the way it is.
Also, you do not have OCD.
"Obsessive-Compulsive Disorder (OCD) is a common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over."
If you turn the screen on and off 30 times before you can make a call, you have OCD. If you have to knock your door five times each time you come home, you have OCD. If you think the smartphone's screen is the wrong hue, that's not OCD, that's just being picky.

Each S7 Edge has different display quality! When you put 2 S7 Edge Side by Side and compare, you will see that the displays have different tint (mostly yellow), and more worse: a lot of the displays are not homogeneous. that means that one corner or side is brighter then the rest of the display.
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
basically i do think that the s7 screen is better, due to the Edge screen is P-AMOLED to be flexible! but the differences between otherwise identical devices are really huge!
i ordered my 5th device today, because all of them had flaws:
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!

I think you're being a tad bit OCD. At the end of the day, the S7 might have a slightly better display than the S7E but the screen size and battery size make the S7E better for me personally. If you're looking for a slightly better looking display then maybe you'd be happier with the S7.

Or, you know, maybe you're looking for a flaw that's not there? It's a well known fact by now that a bend in a display, like the Edge, will have some shifts in brightness, tint and contrast, especially right in that bend! If this is something that annoys you, then I'd recommend you stick with flat panels from now on, because this won't be "fixed" for awhile. It's just the way it is.
Also, you do not have OCD.
"Obsessive-Compulsive Disorder (OCD) is a common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over."
If you turn the screen on and off 30 times before you can make a call, you have OCD. If you have to knock your door five times each time you come home, you have OCD. If you think the smartphone's screen is the wrong hue, that's not OCD, that's just being picky.

Thx for the medical and display-tech lecture, I'm a university lecturer (engineering and physics) myself!
1) Display quality: You did not read my post, or my linked thread regarding note4! The display of note4 was not curved, and had the same problems as all of samsungs amoled devices before: When you compare 10 devices side by side, you will see that each and every device has different screen tone, uniformity, ... About 2 out of 10 I would consider "good", all other have flaws such as a not uniform brightness distribution (one side of the screen is darker then the other side), or bad viewing angles.
this is NOT a problem which every device has, as I always found one device in the past which was "OK" after exchanging a few times.
same happened last week and today: last week i got a device with a really nice screen, but the front cam took blurry pictures compared to the other S7E devices I have in front of me. this can be easily reproduced, so the cam or lens has a problem the other devices do not have.
the device i got today has the best screen so far (good and even white distribution, good viewing angles), the front cam is ok (a bit less sharp pictures then my reference device, but WAY sharper as from the last weeks device), but there is a scuff on the top metal frame of the display, between the glass and the metal. this is no dust particle, it is a real scuff. :| i will test the rear-cam as well, if it is ok i will stay with this device, as the scuff is not nice, but a minor issue compared to the display faults of the other devices.
also, i showed the different displays of all my S7E devices to friends and colleagues (because they thought i'm crazy because of my exchanges), and all of them see the display faults as well. you need to have devices for comparison, then you will notice how bad some screens are compared to others!
so no need to go for an other device as the S7E, because there ARE good ones existing. but you have to be lucky to get one...
on the OCD: this was half ironic, because i know that OCD really is.

I did.... not read that Note 4 thread, and I did (clearly not) understand what you said (blame the beers I had), but alright, I do understand what you're saying now, and yeah, there is a slight difference in each panel, and some will get a slightly better panel than the other one. That happens with every screen out there, including LCDs, and viewing angles are also something that gets affected, but I have the impression that this is more of an issue with LCDs.
I would keep swapping it until I got a good panel, so keep doing what you're doing until you get tired or hit the jackpot. The screen is rated as the best smartphone screen ever, so I promise you it should look amazing. The issues you're experiencing is very common though, and must be somewhat expected when we are early adopters. These are typical issues that Samsung will weed out with time.
I saw a strange think on S7E: the 2 sides of the screen have grey shadow area if you looking at it in a dark room with low brightness of course...is that normal?
My is perfect :sly:

I saw other phones and talked to other S7E owners, and they see this grey halo too, when the brightness is low and the environment really dark. Do you think that it is a problem of my screen?
