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
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.
http://forum.xda-developers.com/moto-x/general/fyi-dim-screen-moto-white-glove-t2753559
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
So I just picked up my Note 4 last night. Coming from a G3. Screen is bright and colors are great. Liking the phone. But one thing that bugs me and it may just be me.. is the color shift during different viewing angles of the screen. Mine turn to like a greenish blue tint when tilted all directions. It's most noticeable on lighter screens. Darker colors not so much.
Does anyone else have this? Does it bother you? Should I go exchange?
Mess around with these settings first
Doesn't make a difference. Anybody else have this problem?
All the displays in the Note 4 have screen viewing angle issues. Some have vertical shift issues wheres others have horizontal shift issues and others have both. People tend to keep their eyes oriented on just the vertical aspect and look at their devices eye-on, a big factor as to why you don't read many others acknowledging this on their AMOLED devices (Note, not just pertaining to the Note 4). AMOLED has perfect viewing angles, the culprit is usually the digitizer and glass which are incorporated on top of the AMOLED screen. The digitzer and Glass are responsible for the color shift due to inorganic elements used to manufacture such components. I've seen red shift to orange when looking at certain Note 4's from a horizontal angle, and I've seen Blues shifting to purple from vertical angles, and I've seen worse in which a demo unit had pink shift and green and blue shift. A replacement is not going to help. The iPhone circumvents the screen viewing angle problems thanks to the separation between the LCD panel, backlight, and glass. Recently, Apple decided to combine the backlight and LCD, thus reducing 3 layers to 2, the results did not compromise the screen viewing angles. IPS displays are still a versatile choice when thinking about appropriate displays. AMOLED is simply good for folks that are addicted to saturated colors.
Never had any issue. When I first got my phone, when I viewed the screen from a heavy angle it had a bit of a pink tint on white colors, but that had gone away now.

Are you using any screen protector as well?
BTW,
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 have no issues. Looks amazing for me
Well after having it a few days.. it doesn't bother me much anymore or I don't notice it as much. Maybe it's going away. I had a few galaxy devices recently and I guess I never noticed. I'm used to my G3s ips screen.
Just got a new S20 FE, I have a Red or Magenta tint on sections of the screen when looking at an angle on the screen and straight directly looking at the screen. It is only clearly visible on a white screen, pretty noticeable when surfing websites, etc. Hard to capture in photos but I tried my best.
The tint will move as you move the screen, and quite bad at an extreme angle. I checked some FE display units in the Samsung store and they all have this issue, some are better than others though.
the XDA review has the same issue actually: https://www.xda-developers.com/samsung-galaxy-s20-fe-review/
"The viewing angles, though, are disappointing because the display still features visible angular color shifting to blue as well as a rainbow out interference effect at extreme angles. Newer Samsung OLED panels have eliminated the rainbow out interference effect, and also reduced off-axis color shifting by a significant amount. The Galaxy S20+’s viewing angles, for example, are much better because the color shifting is much lower. Strangely, even the cheaper Galaxy M51 (review) doesn’t feature the interference effect issue (that is likely caused by the polarizer)."
Anyone else have this issue?
Thinking about asking for a replacement

A lot of phones have some sort of tint or rainbowing when viewed at some angle. I know the pixel 2xl had a very noticeable bluish tint on the whole screen when viewed at angle, but yeah you can still check and make sure.
