[Q] How is the SAMOLED HD Display? Any issues?

The Galaxy S2 is known to consist of many issues particularly with its screen. Although the screen technology is far more superior than the one featured on the Galaxy Note, I wanted to know if the Note has any of the following issues with its Super AMOLED HD screen--
1). Black blotches? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
2). Stains? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
3). Red Tint in Black Background? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
4). White-colored bleeding? (*#0*# Select Black; wait for your eyes to adjust; be in a complete dark setting, and assess for this)
5). Brightness uniformity issue? (One side darker than the other or lighter than the other, vice versa)
6). Color uniformity issue?
7). Washed out colors?
8). Lack of clarity?
9). Horizontal or Vertical lines?
10). Ghosting?
11). Circular mark?
12). Banding? (Use *#0*# to test)
13). Dead pixels? (Use *#0*# and Select White)
Above, are issues I've encountered on different S2's. Please let me know if you spot any of the above issues on your Samsung Galaxy NOTE. I really want to gather feedback on all of the above. Thank you.

I dont see any of the above issues but one issue is the white seems little bluish due to pentile matrix

Some user on another thread just posted a screenshot showing the uniformity issue where right side was darker than left.
Another issue noticed a circular mark
Bluish-tint is normal for Pentile matrix, but is the color evenly distributed?

? I haven't encountered any of the issues that you mentioned on my SGS2, and I've had it for almost 1/2 year now.
Anyways, just picked up the Note a few days ago and still customising to my liking, but so far have noticed (compared to the SGS2):
1. Banding. It's more noticeable (eg. Grey keyboard keys) compared to the SGS2.
2. Tile pattern when seeing grey background (eg. The notification bar)
Sent from my Note

Comparing to my S2, the screen is brighter at 100%, I can read better any text, but I can still see the pentile screen. Not much problem, it is not annoying as hell as was in the first galaxy, but it is there and I can't wait to note 2 with plus technology.
So, on your questions, no to all of them.
Oh, for banding, testing with this image

I can't see banding when I use full screen view on browser, but it is there if you move the image or don't see in full screent. It looks like the stock browser changes the colour to 65k when you make scrolls or something like that to be faster and smoother.
No problem for me.

What is tile pattern? Are you referring to the PenTile Matrix?

Pentile panic

Don't panic. The screen on mine is superb.
I have not looked at any lo-qual 8 or 16 bit images, which will look like so called "banding". Banding is not a technical term, but I know what you mean.
This screen is 24bit, Millions of colors. If you look at 8-16 bit images, they will show banding. On older devices, you would see nothing but banding as they were only 16bit max.
Check out this: color depth
The checkerboard pattern happens when the screen redraws graphics when you resize it.
Zooming out to see a smaller view of a web page, there is a momentary checkerboard pattern behind the image, like the pattern denoting a transparent background in Photoshop. Normal and nothing to worry about. When I think about it, my HD2 showed a blank white background in this situation, not as good as I could not distinguish a page being redrawn and a web connection error giving me a blank page.
Samsung are leaders in the field of screen technology, no? Think about it. Who makes the best TV's? OLED screens are now becoming the TV industry choice of video monitors. They often cost over $10,000. Broadcast engineers are not likely to accept lower grade technology. In fact, LCD's are on the way out.
Don't believe the hype.
This device is amazing.

You can also use *#0*# to assess for banding, although I would believe banding to be common on a phone with greater resolution. The Galaxy S didn't have banding btw, unsure if that had to do with smaller resolution.

I have very noticeable vertical banding. Looks as if you are looking through a screen door when panning. It is especially apparent on the Maps app and any grey/white/green backgrounds. Any fixes to alleviate this, dont want to send this back to UK.

On a grey background I notice what I would call a "hatching" type effect. It almost looks like the thatch grey background on iOS devices.

By hatching, do you mean the yellow-tint like that found on the Galaxy S2?

Yeah I have the thatching effect on mine as well, like you said, on grey backgrounds. I don't notice it otherwise, just on certain shades of grey. It seems that Samsung screens have problems with grey colors, have had simaler problems with my Nexus S and SGII. I think it's just something with the amoled screens. :/

Screen Adjuster

Guyz I bought a galaxy note last week...just out of the box i saw a yellowish tint all over the display basicaly from the bottom left.....
so i got an app screen adjuster
i installed then adjusted the blue at +5 and now 90% of the yellowish tint is gone..
soo i have to ask is it safe to use this app????
heres the link to the app Here!

Sure its safe to use but if your note is flawed from the factory then take it back ??
Sent from my GT-N7000 using XDA Premium App

I use it to lower the contract to -40 as it fixes some of the black rendering issues. I also set the overall brightness down to 75% as it is just set too bright (I turn it off when outside).
I have never fiddled with the colour as my colour renders perfectly. I agree that if it is not rendering correctly, send it back for a replacement. It will likely only get worse.

interesting how it helps you to solve some black rendering issues, but not at all for me.

Yeah its awesome but lags my ICS ROM down

its awesome app ... removes black blocks completely on videos .... is it factory issue with my note .. as i think it should work correctly be default .... isnt it ? ....

For sure is a very good and safe app but better now that is brand new it s better to take it back....

I have observed the similar thing.
I have now bought 4 Notes for myself and my family members (Yeah I know, 4 people in family with Note ). My personal one manufactured in October and those bought recently (3 of them, all made in January 2012) have different colour reproduction.
The new ones have slightly warmer colours when you look dead on (with slight shift to blue when you look at it from bottom at extreme angles which is to be expected).
But straight on, the new Note has colour reproduction similar to my Galaxy Nexus. ITs slightly warm. Its definitely not the colour calibration as it remains same regardless the ROM I use. Its definitely not like traditional SAMOLED blueish display like my old Note or SGS2 which I had before that.
All 3 which are manufactured in Jan 2012 have same colours. All 3 bought from different stores few days apart. But I dont think its bad thing. It actually little warmer like Nexus and is more closer to real life colours. I know that many people prefer artificial looking, eye popping SAMOLED colours, but I am definitely not complaining.

Black colour blocking is universal as far as I know. All of the Notes I have seen have it with hardware accelerated video playback. Using software decoding using players like MX video player or MoboPlayer or BSPlayer solves the issue for now and there is already work under way to fix this issue. I dont think you need to return your phone for this as new one will most likely have same issue.
What I mentioned was regarding general colour reproduction of the screen. The new Notes have slightly warmer colours everywhere. Be it in home screen, browser, gallery or video.

No, it's not faulty. Color banding or black blocks are just artifacts introduced by developers or the video encoding process for the most part - the issue is generally not apparent on TFT display types since the LCD layer isn't able to block 100% of the light to show you a true 'black' pixel.
Good dithering can hide the problem somewhat, but on OLED displays it's more difficult since they are far better with contrast.
You could look at it one of two ways...
You have a superior display technology that the world just needs to catch up with.
Or you have a worse screen because it doesn't hide what other display types are incapable of rendering.
Take your pick : )

Thats a relief ... i was also thinking the same thing as , other colors looks quite nice on my note ... only issue is the blocky blacks which on less resolution videos are more visible .... however i was able to solve the issue using screen adjuster app by setting contrast to 55% ... at that it displays no blocky blacks at all ... just the screen gets an overlay of grey for pure blacks..... i can live with it ...

[Q] Yellow Tint & Brightness issues (again!) - Why??

I know there are other threads that discuss this topic (somewhat) but I wanted to post this separately because what I'm asking is very specific.
I've had about 8 separate Nexus devices from Google Play in the UK and every one of them has had the same issue:
The display has had a noticeably yellow but admittedly slight (possibly slightly brighter) tint on the bottom and left edges, while the right edge has been dull/dark.
This is specific because there are other and numerous reports of a yellow "tint" across the whole screen. This is not the whole screen, this is very clearly just the bottom third and left edge of the screen.
Some think that this is a "glue" issue that will resolve itself. Some think it won't get better. Some think that it's an issue they can live with. Some can't stand the lack of uniformity.
Well I can't stand the lack of uniformity because in my opinion, on a 4.7 inch screen, I find it distracting to be reading text on a solid background or white and the "white" or background colour changes as I read right to left or top to bottom. I consider a decent amount of uniformity to be a minimum requirement for devices which will be used in the way most of us use our phones and tablets. Manufacturers, seemingly, don't care at all except in the most extreme of cases. It looks like they are churning out whatever they can get away with. In all other aspects, the N4's screen is fantastic.
There's nothing anyone here can really do to help directly but it leads me to a question I haven't been able to find the answer to anywhere by Googling or searching other forums:
What is the cause of this lack of uniformity on these LCD panels? It seems to be LCD specific. As mentioned, some think it's "glue" but then others say not and in my experience the tint issues haven't gotten any better in the time I've had the devices that have passed through my hands.
I don't think it's the LED backlighting but could it be something to do with that?
Does anyone know, from a technical point of view why LCD panels are so prone to this issue with the yellow tints across *part* of the display. It's a very widespread thing as it's been noted on most of the iPhone range and a lot of other handsets too. Is there something inherently difficult for panel manufacturers (in the N4's case, LG) to do to make the panel evenly toned and lit? Surely it can't be that hard at this stage in the development of LCD tech once the manufacturing process is "calibrated" at the factory and underway? I assume these handsets are assembled by robots, not by hand. Is that right? Why is it so widespread? Is it a cost issue? Would I have a better chance of a quality panel by buying a more expensive handset? (Although I've seen many HTC One X's with the same problem - I did see one which was almost literally "perfect" in uniformity and brightness). I'd really appreciate any feedback on this. I know that because it's the "norm", sadly, the common response is to now "accept" the panels and handsets that are out there. There doesn't even seem to be a "higher end" manufacturer where high quality uniformity is more likely - or is there?
Anyone with a good/strong knowledge of LCD tech or the manufacturing process out there that can explain this?
Thanks!
***UPDATE***
I've now attached an illustration to show what I mean. ***It's exaggerated a bit*** to show the effect but illustrates the problem clearly.

Have you tried using a custom kernel to tweak the colors of the screen? The Nexus 4 is known for it's washed out colors so using a custom kernel like Trinity or Franco kernel allows you to tweak the color of the screen to your desire. Of course you will need an application to tweak the colors.

LG is known for light bleeding and or panel uniformity issues, I had to swap 4 LG tvs before I decided to go with Panasonic , my LG ips monitor that im typing on right now for my pc has light bleeding in some areas which results in low contrast. I saw about 13 different optimus g devices before I got the nexus 4 and the screens are beautiful with good contrast, punchy colors and good black levels with no light bleeding or weird tints while my nexus 4 has slight light bleeding right where the signal bar is located. I love this phone and its seems to get the " perfect " one you maybe have to swap a few times and to me the price kind of fits the quality of the phone but then I almost have enough spare cash to buy another one lol can't complain about that.

Thanks for the reply. I've heard elsewhere that LG specifically seems to have poor quality panel uniformity. I think LG panels are used by Apple who have had many, many reports of panel yellow "tint" issues on both their iPhone and iMac range. It seems to affect screens big or small. Having said that, HTC had similar problems and their panels were manufactured by Sony. I would *love* to know what's causing this or what is the reason for the yellow "tint" issue on part of the screen.

I have done all of that and with some success with all of the handsets I've had but because the tint affects only part of the screen in a sort of gradient - the calibration cannot fix it.
I'd much prefer a screen that had a yellow "tint" evenly across the whole screen then of course I could calibrate accordingly.

yellow patches is from the glue used in the optical lamination process, yellow tint is from the display calibration which is often used to reduce banding and gives more saturated/warm look to colors
if your device is affected by by visible yellow patches the only cure is to re-calibrate the display to reduce the effect and don't get the device too hot as it may increase it

Sorry but this is not what my OP is about. I do not have a uniform tint and therefore it cannot be to do with "calibration" of some sort unless I am mistaken. Neither do I have "patches" or "spots". This is very specifically about a gradient yellow "tint" that only affects part of the screen and trying to find out the technical reason(s) for its prevalence in a wide range of LCD screens used in mobile phones and of course the Nexus 4 in particular. I've updated my original post to include an illustration of the effect I'm asking about. Thanks!

I am pretty sure its a hardware fault and i assumed you tried to return it otherwise there is nothing else you can do so i suggested calibration to reduce the effect

I had the same issue, then flashed custom ROM and it was fixed. Go figure :silly:

Screen coloring green/blue/etc. at slight angle

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.

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:
https://www.youtube.com/watch?v=aVrm73sAnUs
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).

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.

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.

Great Phone, same old AMOLED problems.

I'm about done with AMOLED panels and I'm about done with the S7 because of it. Ever since phones went quad HD (Turbo, S6, Nexus 6, Turbo 2, Note 5, 6P, S7, etc), this has been a problem, and unfortunately it still seems to exist on the S7. This is my second one - the first one had it in a different area on the screen and it was even worse. It's the pink fade on light or white backgrounds. Once you see it you can't unsee it. I'm sure some will come in here and say they can't see it. I noticed it looks all white at the right angle so if you're not seeing it, you might move your screen a bit. Also, the first image (the horizontal one) shows it the most b/c it has the subtle camera lines which make the fade even more obvious. Not sure if there's a point to this except to vent a bit and, I guess, see if anybody else has had this issue on theirs. Given that the screen is supposed to be one of the main selling points of this device, it's hard to keep it when I see the fade every time a lighter background comes up...
Honestly, I don't really see one benefit to having an AMOLED panel any more - even the highest quality ones eventually deal with burn-in, the battery life is not any better, and they have inconsistencies which are apparently just par for the course. #frustrated

Hmm my S7 doesn't have this effect at all angles and I don't think this is something with AMOLED displays. I think it's the new gorilla glass and the refractive properties of it. At some angles it looks blue and others pink but looking straight at the phone I don't see any weird hue just perfect white. The colours on the S7 display are the best for an AMOLED screen so far and I can say that since I work in a paint store and colour matching is my life.

I know what you're referring to with the refractive properties on Gorilla Glass 4 and this definitely isn't that. I'm even able to see the inconsistencies on darker backgrounds as well. I've uploaded two more photos, attached to this post. That's a solid dark grayish/blue background.

Pick your poison. With AMOLED you're going to get higher brightness, contrast and color saturation, but it will shift colors on whites with various viewing angles. With LCD you'll get colors that are less saturated but more stable and no true blacks (thus worse contrast), and it's brightness, contrast and saturation will all degrade at higher viewing angles.

AMOLED screens are also thinner and consume less energy.

I know, and I guess I shouldn't be surprised. Though I don't think we're talking about just color shifting at various viewing angles. This fade (and prior fades) appears to be "burned" in to the screen itself, and while differing angles help a bit, it doesn't change the problem.

And it looks even worse when you compare it with your friend's perfectly white iPhone screen..
But the better sunlight legibility and perfect blacks appear as a fair trade in for me..

I don't know - obviously that's subjective, but even my iPhone 5S is still just as readable in sunlight, and having inconsistencies in the screen appearance on a $700 device, to me anyway, is hard to justify for the sake of pure blacks.

Many will disagree, but this is why I still think the iPhone 6 Plus has the best display. I own an S7 Edge and while my screen colors are even with no pink tint, the entire display does have a bit of a green tint to the whites and I can occasionally make out horizontal lines where the brightness isn't perfectly even on grays and whites, especially noticeable when scrolling. My S7 Edge is about as good as I've seen any QHD AMOLED display, certainly much better than any of the S6s I owned, but it's still not perfect, and I would still prefer the display from the iPhone 6 Plus. To me, good, even, uniform whites are more important than perfect blacks because most of the things I do on my phone involve white backgrounds (web pages especially).

One thing I would like to point out that you are completely missing is the contrast, not only black-white but the colour contrast! This is another area where S7 screen is clearly superior than 6s plus or any other mobile lcd. You can verify that by viewing a colorful wallpaper side by side on both the screens. Another thing is colour accuracy and colour gamut in which S7 screen again comes on top.
Both types of screens obviously have their pros and cons but SAMOLED screens arguably do have more pros over lcds than cons imho!

Agree 100%. And at least the blacks on LCD's are consistent. They might not be "pure", but they are consistent unlike the whites in AMOLED.

You call it superior, I call it over-saturated (), even still on the latest and greatest. Don't get me wrong, they look nice and my eyes get used to it after awhile, but no matter what I do the S7's screen (and S6's, and Turbo's, etc.) feels "cartoonish" to me when navigating through the UI. Every time I go back to LCD from AMOLED my eyes feel a small sense of relief - almost like the contrast was too much. I know that's not the norm, so fortunately we have choices. But I love everything about the S7 except, ironically, its screen because of these inconsistencies. I simply shouldn't be seeing a fade from white to pinkish grey on an all-white background on a 2016 flagship.

Lol.. it would be a shame then if apple goes with amoled displays in future ?! Anyway you seem very clear about your preference of the display type so I'm not going to contest that, but I would say that lcd displays are not free from fault like amoleds and they do have issues like backlight bleeding, abnormal tints, non-uniformity issues, dead / stuck pixels etc.
BTW, I'm not here to preach about amoled or lcds, it's only my own experience with both the display types in the past. My experiences might vary from yours but I've always had them better with samoled screens than lcds.

I just bought a s7 flat 2 weeks ago and its my first AMOLED phone., i dont have any kind of color uniformity but i can see the strong blue tint in white when i look at the screen from an angle, and its really distracting me too much. I dont know if i go to warranty and they can fix it.

No, as that is the nature of the technology. When viewed at an angle, LCDs maintain color uniformity but lose saturation, brightness and contrast. AMOLEDs shift to blue green but maintain saturation, brightness and contrast. Refer to my post above (#4) and check out the picture.

I see it, and i aggree with you but, color shift is more disturbing then losing brightness. Its not affecting when using phone most times but whenever i use my phone with one hand and try to open notifications, blue tint is appearing and i really hate it. Actually iam in love with blacks of amoled screen, but this thing is driving me crazy. Maybe i am just too sensitive this color changes.
And btw, my father have a Galaxy A3, and it has exactly same blue tint on his phone too. I Think samsung should something to fix it for next Galaxy S. Its really annoying.

It has to do with the varying luminescence and longevity of the various colored pixels. AMOLEDs have been like that since the beginning and it won't be fixed by the next generation of devices. Once you get in the habit of keeping the phone perpendicular to your eyes, it's not so bothersome. Then you go back to an LCD and see that it looks so flat and dim and decide it's totally worth it.

Sorry, didn't mean to sound so dogmatic. I really don't dislike AMOLEDs, the imperfections just frustrate me on such a high end device. You're exactly right that LCD's can also have flaws, but I see them much less than I see them in AMOLED panels - which is just inherent to the two different types of technology and how well the OEMs implement them. I was able to exchange the one in the photos of this thread for a new one (two guys at the store agreed it was an issue) and while the new one isn't perfect, it's MUCH better to where it's not all I see now.

There is truth in this statement. Despite my overall preference for LCD, when I use AMOLED for a period of time and go back, it's a two-fold reaction... one reaction is slight relief on my eyes, but the other reaction is getting used to the "dullness" - though I find I get used to that much faster than I get used to the high contrast when going from LCD to AMOLED. I would imagine if I stuck to a phone for more than a few months and that phone was AMOLED, the change back to LCD would be even more difficult.

Disappointed this is still an issue with AMOLED screens, this frustrated me to no end on my Galaxy S2 where the screen would shift yellow from one end to the other. Glad you posted this thread as it's not a widely addressed issue, guess I'm going with HTC 10.

I've never noticed this on any of my AMOLED displays. Nor have I noticed any burn in, and I'm not sure what you mean by "other inconsistencies," but if you mean sample to sample variation that affects LCD panels, too. And if you don't like the high contrast, that's adjustable in Display settings.
What I have noticed is vibrant color and ease of using in daylight that no LCD panel can match. Or even come close to. I guess I'm done with LCDs.
