No this is not another one of those "I've got a screen issue" thread, For those who still have their Galaxy S1/S2 or even a Samsung Wave, how deep are the blacks on the Galaxy Note compared to them?
I ask this since I no longer have any other SAMOLED device aside from the G-Note and I noticed that the black levels are not very deep, infact they are like LCD's with backlit when you view an all black or watch a movie/picture with a good majority of blacks.
Can anyone be so kind as to test and compare in a dark room showing the phone stock test image found under *#0*# ( dialer ) I've been getting reports from other users that the black levels on the G-Note is not as deep as the S1 or S2, Trying to figure out if this is normal or some really bad gamma issue/hardware limits.
Since there has been a HUGE failure of people reading or understanding what this thread is, it is not a complaint thread its more of an inquiry thread on what you are getting with your screen. Those who dont have a previous SuperAMOLED device you guys cannot contribute anything on this thread since you wont have any basis of comparison so please stop trolling.
Darker than a black steer's tookus on a moonless prairie night.
Anyone else with a meaningful post comparing the S1/S2 vs the Note in black levels?
Like any other OLED technology, there is no backlight, so the blacks should be as black as if the screen were off.
What you might be noticing is fringing, the light leaking out from the neighboring pixels.
It could also be an optical illusion (you are seeing a black object with lighter surroundings it might make the blacks "not seem as dark"), I tested it myself, I got an opaque piece of paper with a small hole in it and placed it against a black part of an image, and compared it with the screen off. It looked the same to me.
I can't compare it with the S1 or S2 since I don't have them, but with as with any other OLED screen, as long as the black parts of the image is truly digitally black, as in that part of the picture is 000000 on the RGB color model, it should be equally black as if that part of the screen were off.
No difference in the black levels when they are properly rendered on the note vs gs2. The software bug though sometimes makes blacks grey so viewing the same video on both screens dark areas look better on the gs2. This will be fixed with an update and as others have said true black=off with oled so black will be black on any oled screen.
In gallery i get true blacks and images look the same on both screens apart from much bigger and sharper on the note. If i make this image a lock screen its sometimes grey with banding on the now instead of true black.

Don't know about black, but the screen it's forkin bright, too bright for day time use even on the lowest setting
The Black arent 100% fully black. If you turn the lights lights of you can see some very very deep grey. It black enough tbh, I am not complaining!

If you have a phone with a SAMOLED screen go to a black room and bring up the LCD test menu, the black is at 000000 and you will see a faint glow, you can very easily tell if the screen is displaying a black color or if the screen is locked. Why websites say their testing machines report infinite contrast ratio is beyond me.
If you cant tell the difference of the screen displaying black and when the screen is locked ( off ) either you got the most absolute perfect screen or you need to actually check rather theory craft.

The main point of my question is not about "when rendered properly" just bring up the LCD test menu on your galaxy note and galaxy S2 and check if the note has a higher glow on its black levels. mine is extremely high from what I can remember on the Galaxy S2, infact I can label it an an LCD backlight instead of SAMOLED blacks. But if im in daylight the blacks are pretty good.

Its not about complaining, I just wanted to ask for those who have the note and also have the S1/S2 to make a comparison if the black levels are similar.
Im at a loss as to why this feat is extremely hard for the people who replied on the thread so far, I guess I am asking to much.
No one has the S2 and S1 and the galaxy note. why would they? the note is amazing!
Galaxy Note black has more leak than previous Super AMOLED and Super AMOLED Plus screens.
I'll come up with measurements a bit later.
well, Kabayan i have both... i can confirm your finding that S2 does have deeper blacks... last night i viewed the Dota2 trailer video on S2 and Note side by side... @ the beginning of the clip where there are lots of black displayed, its noticeable in my eyes...
I decided to create a pure black wallpaper on photoshop, transfer it to S2 and Note, set both brightness @ max, go to the complete dark room and view the mentioned wallpaper on gallery; its positive that S2's dsplay shows deeper black than Note... Though i have the display tuning app by SUPERCURIO on my S2 which i think we'll also consider...

An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than liquid crystal displays (LCDs). In low ambient light conditions such as dark rooms an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses either cold cathode fluorescent lamps or the more recently developed LED backlight. Due to their low thermal conductivity, they typically emit less light per area than inorganic LEDs.
When the display is "showing" black, the "black pixels" are actually inactive. In other words, the black parts of the screen is off.
The black levels on my screen is also 100% black. If i go into a dark room with a 100% black wallpaper, i won't see the screen.
I have an S1, S2 and Note. Showed all 3 at Samsung service centre just to prove the Note's screen was crap. Should be getting it back to day with a new screen. The S1 screen still seems the best in terms of brightness and uniform white.

Yay supercurio. It's good to see you.
It does have more light leak on pure blacks, but coming from an Atrix (LCD) and an S2 (WVGA), I still love this display the most. The resolution is insane.

Did you happen to get a photo of it?
I compared both with a clear black test screen from walvisions.com min and max brightness blacks where the same to me. I must have a perfect screen or you have a very bad one.
But like i said in my previous post the blacks when actualy in use watching a dark video are much better in the gs2 for what i think is a software issue as they arent rendered properly and dark areas tend to look more like backlit lcd on the note when viewing videos.
Whites are much brighter on the note with min brightness settings then on the gs1.

It is not true, you really should try it before just quoting wikipedia or whichever website that quote came from. Even with a perfectly black image you can easily tell there is backlight.

Very true, the S1 screen was really great.. it really brought the expectation level at an all time high.
There's a lot of variation on the screens we are getting, my Galaxy Note screen has no color variation, banding, dead pixels, and the blacks are real black. In a dark room, displaying a black image, I can't see the limit between screen and plastic bezel. Exactly as with the screen off.
The same with video playback. I recommend to use BBC One Human Planet trailer in HD. It has a lot of colors and transitions to black screens. I see the screen completly back, no difference to the black plastic bezel.
This is a black Galaxy Note, on a black background displaying a mostly black image. Brightness set to maximum.
Now you tell me you can see the limit between SAMOLED screen and plastic bezel

No color variation is plausible, banding is SW issue so nobody is excepted from it unless you can prove it, dead pixels are pretty rare that its a non issue, black levels are lit let yours eyes adjust to the darkness for 3~5mins and you can clearly see a lit black its always been like that since the SGS1 days, your phone is no exception.
Your screen is perfect for you, I respect that and Im very happy for you, wish I had that screen. Cheers!
Response to your added image:
Your image proves nothing since the discussion is about black levels in total darkness while displaying the black image from the LCD test, your picture shows an image displayed making an illusion that the blacks are very deep, I also get the same black levels when im displaying even just a few pixels of white and you have ambient light since I can clearly see the bezel.
Basically we are comparing 2 different things but thank you for trying.

Seriously who uses a phone like that and whats the point of that test. OLED does show a little light in the dark when you do that but my GS2 and note are pretty much the same, during this test I notice some darker blotches on my gs2 screen. Does that mean its faulty? not to me as Ive never noticed it in real use and thats what the device is for not to sit in the dark for 3 minutes to find some obscure issue to complain about.
There are real screen defects that will occur to some people not matter what device you get, then get it replaced. There are confirmed software issues and these will hopefully be addressed soon enough.
Many more people have no physical issues with their screens then the ones that do but its funny how some people just wont accept that and have to believe every screen is faulty.
Seeing a little light through a screen in total darkness is not a hardware fault, maybe you should turn off your phone as it will save your battery and at the same time the screen will be perfectly dark, I prefer to have my screen on and use it but we all use our devices differently

I haven't received my Galaxy S yet but everytime I use my friend's I think the screen is just too blueish. Mostly the white parts. And I also think a "square field" is visible all over the screen. Is this because the resolution is too low compared to the size?
The phone itself is great so I still want it, but I'm afraid the screen will make me disapointed, especially since I've read so much about the Super AMOLED is so great.
Are all Galaxy S' screens like this?
What is the "square field"? please explain better.
And let's start from clearing the point of resolution/size-
800X480 is more than enough to go up to 7". If anything, it might be the pentile matrix that the screen uses.
I guess it's these "squares" I see: http://www.engadget.com/photos/iphone-4-vs-samsung-galaxy-s-display-face-off/#3115591
You're probably right that it's more the pentile matrix I notice more than lack of resolution.
I cant understand why many reviews says this screen is very good when it's very noticable.
I've seen mentions of different Galaxy S phones having different colour temperatures, though mine seems fairly cool.
PenTile does, unfortunately, make text less sharp, and there is a bit of a screen-door effect (I think that's the term you're looking for). It's a tradeoff for having a Super AMOLED screen - excellent contrast and very bright, but not as good as a TFT for text. I've become accustomed to it though, despite my misgivings (but a non-PenTile SAMOLED really would be the best screen without question).

What's the good side with PenTile? And yes, I've searched for "screen-door effect" and it seems as if that is what I'm seeing.
Yes, Galaxy S display seems to have quite high colour temperature. You can sort of calibrate it using the calibration app that was developed for Nexus One a while ago and is now part of CM6, but you have to run Froyo, install it manually and lose video overlay, so it's not really usable right now. Nevertheless I've managed to calibrate my SGS to more or less 6500K using it.

Oh. Well, guess I'm not going with that solution then
But since it can be done through software, does it mean that Samsung could make an update and fix this?
I had this on my old galaxy S and coming from the x10's tft it was painfully obvious the white colour had a blue/green tint to it. I then got it replaced and the tint was still there but not so obvious. Now after a while the white colour looks perfect white. I think my eyes have adjusted or something.

My friend got a blueish Galaxy S I9000. Mine isnt that much!! Next to his looks like mine is Redish, but mine next to my Monitor looks blueish! I believe some Screens have more blue tint than others
Mine is very white. Put the phone on a white screen (using a screen torch app) and the screen looks whiter than a piece of white paper.
Hey all, keep us updated if there's any application that can change the color temperature without affecting the functionality.
I got the phone a few days ago and my friend's is defenitly more blueish than mine. I dont notice the screen-door effect anymore so I'm very very happy with it.

I´ve read something on a German Mobile Phone Review Site (don´t know the which one it was now) and they said, that this is normal, because of the AMOLED Tecnology. They said that the Colors will loose the intensity over the years and as blue is the most energetic Color in the spectrum it looses faster the intensity. That is why it looks now maybe a little bit diferent. After a while it should normalise, because it was planned by the manufactures.
Ok found the Site. Heres the translation:
Higher blue components of the display of the Galaxy S may have been deliberately created by Samsung with the idea that the blue OLEDs are aging much faster than green or red. After months of use should mitigate this effect and color balance to be balanced.

They could do that if they wanted to, yes. But don't expect them to do so, I don't think colour temperature is of any importance to them if it stays within usable range.

Got this tip a while ago on some other thread - you can start Video player, play some video, go to Settings and change the Colour tone to Warm. It stays changed even when you leave the player. It's not perfect, but it helps a bit.

Actually, YES! Your eye do adjust to the white that you are looking at.
You've been doing this all of your life and haven't noticed it. The light in the morning is a very different color than the light at noon. In the morning, it is likely very red if the weather is good, and very white at noon... yet everything looks normal to you... because your eyes adapt to the color.
Adjusting to your screen is the same way. But compare it side by side with another screen and one or the other is going to look "wrong", usually the one you haven't been staring at all day!

Congratulations, your brain has created a special filter, using a process called "adaption", by the human vision scientists, that blocks the screen-door effect. You didn't know it, but your brain created one years ago that blocked out the 'striped-lawn' effect caused by the columns of RGB subpixels on conventional color displays. That 'striped-lawn' effect was just as visible the first time you saw one, but that was likely many years ago.
Okay so this blue tint thing is somewhat strange, still no clear answers.
Some people are saying "this is normal for super amoleds." I have to disagree. If this was normal, then every single Super Amoled would have this blue tint. I've put my samsung galaxy s vibrant side by side next to the samsung galaxy s epic, fascinate, captivate and other vibrants. Some have a blue tint, and others don't. Others have nice rich whites, while some like mine have a blue tint.
Makes no sense, so I'm not buying the "all super amoleds have this blue tint" statement. They don't all have them!
I've used my phone for over 2 months now, and the blue tint is not fading at all. Something else people said. I don't plan to keep this phone for 10 years, waiting for the blue to fade, I want nice white now, not blue whites.
Anyone have any updates on this blue tint some galaxy s phones show?
Ok so I was about 98% set on purchasing the G2x/O2x but then realized it had a WVGA screen. Isnt that outdated?
I really liked the Galaxy S and above because of the SUPER AMOLED. I have an MP3 player with that screen (Cowon) and its great looking.
I am looking for comparison, if WVGA is fine and bright, perhaps comparison in sunlight, etc. I thought AMOLED was the next big thing and all phones would have it.
WVGA is the screen size, mate. It means 800x480.
For the screen, yes, it is not AMOLED which is brilliant to display black color but poor in direct sunlight. It is supposedly more engergy saving (but then you need to increase the brightness in sunlight)
The TFT IPS LCD that Optimus 2X has is very good indeed in my opinion.
Personally i prefer the screen on the O2X, i don't like the colors on the Amoled, not realistic at all
Sent from my Optimus 2X using XDA App
The IPS screen on O2x are brighter, sharper and with better colours than Amoled - its also better in the sun and have as good viewing angles as Amoled. The only thing where Amoled are slightly better is pure black. It's the same type of screen as the Iphone4 (actually its LG that manufactures the screen for Iphone4 to Apple) - except the Iphone4 screen has higher resolution.
You wont be disappointed about the screen on the O2x - it is very good.
Mate. LG screen clarity is outstanding, sunlight, clublighting, office home you name it. I run it with auto off and at approximately 20%. So brighter is available.
You will not be disappointed.

Thank you for all the responses and clearing up. I was lookiing everywhere for the info on what the screen was, it was strange because one site just said "WVGA" for g2x and the galaxy it said AMOLED so I wasn't sure.
G2x is now still at the top of my list =) I am deciding between this and when the Galaxy S II comes out, seems like slightly better hardware, but dont know other details

I came from the Galaxy S to the OP2X, so I can report for you
The Super AMOLED of the Galaxy S is nothing short of glorious. Even though it uses a "pentile grid" subpixel layout, it's crisp and bright. It's even readable in daylight.
Coming the the OP2X and its TFT LCD, I was very pleasantly surprised. The screen has great viewing angles and almost no colour warping at high angles. The blacks are really deep, so the contrast ratio is much better than I was expecting. If I hadn't experienced the SGS screen first, I'd be utterly in love with the OP2X screen. As it is, I'm 'merely' very happy with it
Having spent 4 days using an S-LCD Nexus S, then going back to my AMOLED Nexus One, I can say that the S-LCD is miles sharper than the AMOLED. OK so you do lose out on a bit of black, but not being Pentile does make up for it.

Thanks, a viewpoint I was looking for =) I guess that eases me. Yeah I was concerned about the viewing angles, crisp of the colors and daylight viewing.
Do yourself a favour and go somewhere where you can look at the O2x screen live - anyone having concerns about the screen should do that - and be pleasently surprised
It really is very good - high contrast, high brightness, excellent colours with no banding, excellent deep blacks (for an LCD), good viewing angles etc. - viewing pictures of real life scenarios on the screen is a treat.
It actually makes my Desire Amoled screen look slightly dull
I sit on a bus and can read just fine. And its been really sunny where i am at the mo.

LCD vs OLED
I wish people would just stop using 3-4 letter abbreviations for screen resolutions. In the early days (80s and 90s) there only were a few of these abbreviations and they signified a lot more than just resolution, like color depth and graphics capabilities, but now they're just confusing. Why not just put the two numbers and save everyone the trouble of having to google what WXSDHDGA (don't bother, I just made it up ... at least, I hope so) is supposed to be.
Back on topic.
OLED
Black is really, totally black. The contrast ratio is technically infinite, but that isn't just a good thing, as it hurts my eyes in the dark. It's a bit like staring at a television in a pitch black room.
Colors are more vivid (read: oversaturated). Most people love that but to me it just looks unnatural. Like kid's toys.
The pixels will degrade rather quickly and lose brightness in the process. Since each primary color ages at a different rate your color balance will shift. You should be good for 2-3 years, though.
As long as the image displayed is mostly black or dark, it'll use less power than LCD, on bright images a lot more. Setting your background to pitch-black is a real power-saver on these devices.
Most OLED displays currently on the market use something called a PenTile matrix (see http://arstechnica.com/gadgets/news...exus-ones-screen-science-color-and-hacks.ars/ or just google it), where each pixel only has 2 subpixels instead of 3. As a result pixels cannot independently display every color but need to work together with adjacent ones, which reduces the effective resolution of the display by at least 1/3. Photos and Videos still look fine, but text gets ragged colored edges and is a lot harder to read than on an LCD.
Handsets with OLED+PenTile matrix, f. ex.: Samsung Galaxy S, Nexus One
Handsets with OLED+full matrix, f. ex.: HTC Legend, Samsung Galaxy S2
LCD
You won't get black, only dark gray, because light emitted from the backlight can't be perfectly masked. As long as the display is on it will emit light.
Power usage is just dependent on the brightness setting, not on the content displayed.
AFAIK all current LCD displays have a full subpixel matrix
A lot of the rest, like color, viewing angles etc. depends on the panel type used. Usually that's TFT, which is kind of meh, the premium choice is IPS (iPhone 4 and some LG phones, like most (all?) 2x variants).
The choice between a (full matrix) OLED screen and an IPS LCD is a matter of personal choice, if you can't get either, get a TFT LCD. Personally I'd never buy anything with PenTile, but, well, some people like it so YMMV.
Going by my preferences and specs alone, the iPhone 4 currently has the best mobile display, followed by the LG Optimus Black / Speed (2x). Since I don't like iOS that would make the 2x the handset of choice, if I needed a new one right now. As it is, I'll wait for the SGS2 and see how that stacks up, first.
I'm brand new to the world of Smartphones, and hence don't have much perspective, but I DO have direct experience comparing the 2 types.
I started last week with a Samsung Galaxy S 4G with the SAMOLED(+?) screen. The screen on the Samsung was very, very nice. As others have said, the blacks are TRUE black and hence everything tends to "pop" more. Think of it kinda like a plasma vs an LCD HDTV. Plasma blacks just can't be beaten by an LCD.
I moved to the G2X two days ago, mostly because I decided I wanted as close to a stock Android experience as possible AND a more future-proof dual core phone. I have NO complaints about the screen on the G2X. Sure, the blacks aren't quite as black, but the colors look great, it's bright and readable, and I don't use a black background anyway. As an added bonus, it is MUCH easier to read in sunlight than the SAMOLED was on the Galaxy.
Just got mine today. Nice phone, but the screen.....
The top left and right corners of the screen have a small white glow, the same as some lcd tv's had in the beginning. So the "color" black isn't covering my whole screen....
This is NOT my phone, but just to show you where the glowing parts are.
Mate, isn't that the lg notification bar? I've heard about some people having backlight problems though, but than it is your phone

Having spent 4 days using an S-LCD Nexus S, then going back to my AMOLED Nexus One, I can say that the S-LCD is miles sharper than the AMOLED. OK so you do lose out on a bit of black, but not being Pentile does make up for it.

The UK Nexus S isn't S-LCD, it is S-AMOLED.
The i9023 is sold here and is S-LCD, we get the i9020 as well though.
I've had my N7 for a week and a half now, and there is only one flaw: I have a 1.5cm dark band down the right side of the screen. It's only really noticeable on white or solid pale colours, so for videos and games it's fine but it's a little distracting when reading black on white.
I have only the slightest amount of backlight bleeding round the edges, even under extreme conditions (ie. full brightness in dark room,) no dead pixels, no ghosting, no issue with washed out colour. So I'm just wondering if it's worth getting a return or just waiting to see if it evens out a bit.
I haven't found any mention of similar issues on the forum, so I'd like to ask how people are finding the uniformity of the display?
same problem
I have the same defect.
How did you resolve? Did you get a replacement?

I think I might have the same problem. But with mine it only shows after having the screen off for a while, and it slowly fades to normal after the screen warms up.
So far what I have done is have all dark themes so I dont see it anymore. Have tried to refit the cables inside and using pixel fixer apps, none had worked.

My Moto X screen looks too yellowish compared to other LCD display phones like Nexus, iPhone's etc. Is it the issue with Moto X's Amoled display or something is wrong with my device?
What you're noticing is just the inherent difference in color reproduction between AMOLED and IPS displays. Most IPS displays have cooler color temperatures and do a better job at producing a true white although with less color saturation.
That being said, I have gone though 2 Moto Xs and the first one came with a very poorly calibrated display and a gross greenish tint. My second one was much better, but I returned it for other reasons, future burn in being one of them. Burn in is different from the problem you're seeing and can best be described as bad tan lines. Some areas of the screen will have different brightness (mostly the nav and notification areas) and it will be obvious when you switch to landscape mode that something isn't right.
If you think something is wrong with your screen and still have a valid warranty, give Motorola a call and let them know about it. They seem to be pretty good about making things right.
No screen burn for me... Had the phone since January and mostly a heavy user too. Maybe no burn because I keep the brightness level down most of the time?

Frankly, it's just a case of not taking care of the fact that we're using OLED tech which is sensitive to static images much like Plasma tech. If you're on Kitkat and use transparent bars like most of us: I can't imagine how anyone could suffer from burn-in that won't go away with time.

But I did not keep it long enough to notice burn.
No burn in here, but I use fullscreen so I don't have a notification or navigation bar.

This is absolutely wrong, no offence. IPS displays do not have any cooler colour temperature! They are less saturated than AMOLED displays mostly, and thus the colours look less vibrant, or more accurate if you will. At the same time they will look extremely dull / pale. If possible just look at the S5's display, it has the best white I have seen in a while, neither yellowish or bluish, near perfect.
And yes, I agree with OP, there is a slight Yellowish tint on mine. This reminds me of the the Galaxy S2's display panel. There is nothing you can do other than getting adjusted with it, but you can try increasing the Blue bias of the screen, to something like +3 or +4. There is an app called Screen Adjuster on Google Play to do that. I am using that now, never thought I would have to use it again since S2 days. By increasing the Blue bias the screen will look little "cooler", the Yellowish white will become Bluish white.
This has nothing to do with burn in by the way.
I should have been more clear about that. It's the backlight source that affects color temp the most. Since most IPS displays use white LEDs for backlighting they appear cooler than many (not all) AMOLED panels and older TN displays using CCFLs. Since the individual pixels are their own backlight with AMOLED there is more variability in color reproduction depending on use and calibration.
And it does have something to do with burn-in. If you have a mostly blue background then those subpixels will see more use than the red and green subpixels. Once the blue subpixels fade enough you're left with a yellow tinted screen. It's not burn-in in the traditional CRT sense, but it's still uneven wear. IMO: The small perks of Active Display are not worth having a screen that can be damaged by normal use.

Questions go in the Q&A section.
I called up Motorola customer care and they asked me to visit nearest service center. They will have a look and decide if anything is wrong in the device. So, this yellowish tint is bit common in Moto X due to AMOLED screen.

It can be. There's a member around who got like 4 replacements or something....all with different degrees of it.
I find you don't notice it after a bit.... Unless you put 2 phones side by side.
Personally it doesn't bother me....it would if it was too yellow. I find the dimmer the screen, the more you notice it also.
My first moto x I had since October got burn in around January. I got a new one in June and I have burn in again. It isn't enough to warrant another replacement (yet).
Can someone explain to me how this phone suffers burn in? Burn in is a thing from old CRT televisions, not really the new LED screens (at least, to my knowledge)
i've always used gravitybox to give the statusbar a grayish color instead of black (and here lately the tinted statusbar xposed module) and keep it in expanded desktop with pie controls, so there's no nav bar, and not seeing any burn issues yet, had it since Dec. the horrifically bad burn in on my note 2 is what made me want to be extra careful with the x.
No burn in here after 7 months on mine nor my sister's Moto X.

Burn in is common in amoled type displays, specifically on phones such that rely on a nav bar instead of capacitive buttons. The longer the screen is on, or the higher the brightness, the bigger the possibility for screen burn in . Out of the three amoled phones I have owned, the two that have burnt in both had on screen nav bars. I hope this (non technical) summary helps
Hi,
I'm planning to get the 64GB Blue Nexus 6 and i have a few questions before i buy:
I heard that the AMOLED Screen have some issues like burns on the screen. Is that true?
Also i heard about "pink" issues with brightness. This is true also?

The at&t variant I personally own never gave me these issues. I have read the pink tint issues were associated with the adaptive /automatic brightness enabled?! Yet, on mine I saw no pink with it enabled or disabled.
And there are videos on YT showing burn in. It is basically the soft keys at the bottom. Triangle, circle, and the square are the culprits. But again no issues for me.
Now the very 1st day my phone did a random reboot on me - twice! But, as soon as I unlocked bootloader, rooted it, and used a custom recovery the reboots never surfaced again! Go figure?! And the nexus 6 is definately the fastest performing phone I owned yet

AMOLED's can all have that issue, but I personally have never seen it happen (I have had a gnex for almost 2 years which used AMOLED and doesn't have burn-in). The pink "issue" isn't really an issue, google allowed the screen brightness to go extremely dark on the N6. This causes the screen to take on a pink tint simply due to the way amoled's function at that low a brightness. The screen does have a warmer hue to it as well because it is AMOLED, but you can use a custom kernel to tweak RGB values and give the screen a cooler tint. Hope that helps

Thank you for that useful information mate.
So, all AMOLED's, regardless if it's the N6 or not, suffer from this issue?

That is correct, all AMOLED's are susceptible to this because of the O in AMOLED, which stands for Organic. The organic compounds that are used in these screens are susceptible to burn in due to the fact that the organic compounds degrade with a lot of use. Of the RGB subpixels, Blue subpixels degrade quickest. However, the N6 uses a Pentile pixel arrangement. This has upsides and downsides, but it is actually an upside as far as this issue is concerned, because the Pentile layout contains less blue subpixels, so there is less susceptibility to burn in.
If you want to combat this issue further, you can use blacked out google apps, and use ROM's with blacked out system options, use a mostly black wallpaper, etc. This is because on an AMOLED screen when the screen is black, the pixels are not displaying any light and thus are not degrading at all. This should reduce your chances of running into the issue. It will also save battery life since the screen is not using as much energy. That is one of the upsides to AMOLED screens, along with the very dark blacks you get in movies and games for the same reason (pixels are not lighting at all). Like I said, I've used other AMOLED screens and not run into this problem as of yet, to my understanding it should take years before you start to see burn in even with normal use. Some people say they have issues right away but that has not been my experience.
All screens of any technology are correctly color calibrated at a given brightness and are very far off at extremes. With an LCD, it will generally be too blue at high brightness and not blue enough at low brightness. That is because the backlights are never a 6500K source. They are basically always bluer than standard.
The Note 4, to pick an AMOLED example, does not get red at very low brightness, but that is because it (according to others) has a higher minimum brightness. My screen takes on a red tint when in a dark room with adaptive brightness enabled if I have the brightness slider set below about 30%. I consider this a handy feature since I don't like the feeling of staring into a light bulb.
Above about 30%, or in a room with a light on, the screen stays normal for me.
I have not seen thecpink issue on my N6 at all.

Not sure about the bottom paragraph, surely you mean inverted colours? Also If you use a mostly black wallpaper you're more likely go get burn in because the pixels around navigation buttons aren't on at all and are thus not degrading whilst the navigation buttons are fully on and are degrading.

Inverted, blacked out, I don't think there's a difference. The button icons themselves will eventually burn in because they are almost always on unless you opt for pie like controls, but like I said that should be over a span of years. A black background will keep everything else from wearing faster though and should give you better battery performance.
I have had the phone for a week now and have not seen either of these issues. I do keep my screen fairly dim, like minimum brightness PLUS a screen dimmer for the nights and early mornings. I do not see any pink what so ever with adaptive brightness off and the minimum setting for brightness. I only turn the screen up when outdoors. I don't know I just find the screen really bright while indoors and I would assume burn in would be more susceptible with higher brightness
So i can safely buy the device right?
Anyway i have to order the phone overseas (No 64GB avalible in my country and the price tag too high anyway).
