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.

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...

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.

Fix uneven/yellow screen with intentional burn-in

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!

Galaxy S7 Edge vs S7: Display Issues

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.

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.

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?

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.

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.

Mediocre - Subpar screen quality

My 32/3 Mi Max just arrived today, not too happy with the screen. It seemed so dull, some leaks on the edge. No competition between AMOLED screen and this. But the 7' LCD of 1920x1200 mediapad X2 is still a height better than this. Heck, even redmi note 2 is better. A little disappointed, glad I didn't go all out with 128/4 version.

Mine isn't that bad. Download Color Changer Pro from the Play Store. You can increase the saturation and colors in it. Mine almost looks as good as an AMOLED now minus the blacks.

The screen protector you have reduces screen quality especially black levels. 100% the cause. Most of the full cover glass for 2.5d screens does not actually adhere to the screen reducing contrast.
The screen quality is v.good although it uses software contrast boosting to make the colors nice, which can crush some details in colors.
Take off the screen prortector and show the same photo, you will see the big difference.
Btw what case do you have?

I've made some comparison photo from some of my available devices on hand. It's horrible, They're definitely cutting corners on the screen. Even my $60 Alcatel phone looks better. My Mi Pad, and Redmi Note 2 have the same "washed out tinting" issues, but this is definitely worse than that.
Just for a note:

Did you read what I said about your screen protector.
The screen is IPS, there will always be changes in brightness when viewing off axis. It's called IPS glow. Depending on the screen, you will see it more from different angles. Mi Max might look better at a different angle than the other phones.

Now you can see the contrast is increased and black levels are better.
This is why I hate phones with 2.5d screens. You can get these full cover protectors which reduce quality or normal glass protectors which don't cover the screen fully. There is also tpu screen protectors which will cover fully without reducing quality, but they feel a bit rubbery and are hard to apply.

I forgot to put the note on the bottom, I took off the screen protector.
All LCDs have that bleeds, glows or whatever you want to call it, I'm well aware of that. But, If you need to put your phone in an angle to get correct color reproduction, i think it defeats the purpose of "IPS" display in the first place.

IPS screens don't really have a purpose, it's just a screen type. Every type of screen has its flaw.
Amoled has image retention and must use pwm to reduce brightness. Some people notice the flicker/eye strain from it.
TN panel has inverted colors instead of ips glow. IPS still has better viewing angles and IPS glow is only noticeable at certain angles.

I have to agree that the full screen coloured screen protector is POS, just realised that it doesn't have any glue in the middle, making some gap between the screen and the protector. Gonna order some better one.
Besides the screen, it's a solid good phone I reckon. I get more than what I bargained for because it's really is an inexpensive phone.. too pampered by AMOLED I guess.

The battery life is amazing. I recently got the 3/32, currently 8.5 hours SOT and 40% battery left.
Hows the miui 8 rom? I've left mine on miui 7 for now as I've read some bad things about it on the miui forum.

There is some full coverage protectors with glue in the middle, at least for other phones. Not sure if there is one for mi max but if there is, they are very rare.

It's fresh out of the box. Haven't really tried anything yet, but I'm on 8.0.1.0 apparently. I'm not sure about the battery life.. I'm more than happy to get 6.5hrs sot. My daily driver is iPhone SE, hands down its a beast of a phone, 9 hours on time give or take.
I just ordered Nillkin glass protector for my mi max, kind of expensive, but can't go wrong with that one. Please share with me if you found any good full screen glass protector.

The big draw of the Mi Max screen is the size, not the color accuracy or black levels or brightness. It's an average screen, not mediocre like a lot of cheap Chinese Android junk but not as good as an LCD on a flagship device. AMOLED is on a different planet because of the crazy saturation and inky blacks. I've had a few phones with AMOLED and although they're great for viewing photos and videos, they're not good for web surfing or working with documents because white draws more power. I didn't have any issues with burn in though.

1. The photo attached in the first post doesn't actually have the mi max in it. I suggest you remove it.
2. Second, the comparison album you made on imgur has software buttons and doesn't actually show that it's a Mi Max, while the separately attached photo in that same post has the xiaomi rom running. The separately attached photo clearly shows its the Mi Max and the display looks great to me with no issues.
My personal experience is also that the screen is great and I'm not sure where you're coming from...

In the first post, Mi Max is the middle phone. The user has installed a full coverage black glass screen protector which reduces the contrast as there is an airgap between it and the display.

I thought long and hard about wading into this thread, but after using the phone for a week I figured why the chuff not.
So, yeah, after 7 days use I've got to say I think the screen is pretty great! I haven't seen any hint blue tint I've read about in a few reviews, although, my device is much newer than the first batches and preproduction models, so that could explain it.
It's not as punchy as an AMOLED, but AMOLED colours are often way inaccurate. Which brings me to my next point, I find the screen pretty spot on in terms of colour accuracy (visually speaking at least, I've got no idea as to the reproduction of the panel on a spec level). It's definitely an improvement over my Meizu M1 Metal.
For the money, it's hard to fault this device. It's by no means perfect, but it's 1/5 the cost of a Samsung Galaxy Whatever.

It is a bit on the blue side but just a bit & you correct it with enabling reading mode & moving slider to the beginning position.
Did my own view test today by using MX player & putting it in to the 32 bit RGB display colour format and then I played a 10 bit Hevc movie. Well the display is quite good but nothing mind blowing. Luminance is an a down side required for something like HDR but it can pass presumably if you use it in controlled darker environment. Actually with brightness set to 11 out of 15 possible (which translate into 73.3%) its good enough but if you go over that contrast and with it quality begins to go down drastically, 12 (80%) is top & even that I would call a compromise. Don't be missed by this for a mobile phone LED display this one is perfectly fine, not a stellar one nor the best one out there but perfectly fine. The little more brighter displays won't make much of the difference between 450 & 550 nits their is little to non difference you will be able to see in this particular case regarding LCD's, next category should be a 700~1000 nits but mobile phones & only couple of them are stepping in lower margins of that category.
At the end I just can't not to wonder if the guy who did a calibration of the display had a little problem with its eye sight because you see as much a display is on a cold (blue) side & that is minimal a tad or two the photos (with main camera) are proportionally on the opposite warm (yellow) side.
Best regards.
