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
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.
If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the Google Pixel 2's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!
Some brief observations about Pixel 2's display (in Natural and Boosted color modes):
+ Max brightness is pretty bright, and should provide adequate visibility in most conditions.
+ Nice, deep, inky, and uniform black, just as you'd expect from an OLED.
- Pure green (#00FF00) renders considerably lighter and paler than reference. Using my eyes alone, I can't tell how much of this is due to undersaturation vs color inaccuracy. The result is that elements that are mostly green (e.g. Google Hangouts icon, plant life in photos) sometimes look noticeably less vibrant in comparison to other elements on the screen.
- Red is undersaturated relative to the other colors. This is evidenced by the green tint that is clearly visible when viewing yellow and orange colors. Deep reds skew slightly purple as well.
- The display's color temperature appears cool in all but the brightest of indoor viewing conditions. I'm sure it looks neutral (i.e. great) under the blaring fluorescent lights of an electronics store, but isn't as well suited for home or office viewing. Some people prefer cooler colors. I'm of the mind that neutral or very slightly warm color temperature displays are much easier on the eyes and more visually appealing.
Most 2017 OLED smartphone displays I've seen have the problems I've listed, albeit to varying degrees. I'd chalk it up to the difficulties inherent to OLED screens, but past experience suggests otherwise: I've owned OLED phones with better color accuracy all the way back to 2013. It seems like things really got worse this year. Not sure if its the displays themselves or the color profiles being applied.
Using the new Saturated color mode swings the color temperature to a more neutral position, but the resulting appearance is way too saturated in general for my liking, and it doesn't completely resolve the issue of inaccurate reds.
I'm disappointed, as the display's color issues cause it to fall short of what I expect to find on a phone in Pixel 2's price range. I haven't decided yet whether I'm going to keep it.
Yellow!
Receive mine today, and the colour calibration was way off... I thought it a little yellow at first, and perhaps the beach on the default wallpaper might be influencing my judgement. Installed a few aps, played around with the settings, and then compared it with my previous phone and oh dear - it was clearly very yellow. Greys in particular looked awful, and whites like aged paper rather than white. So disappointing.
I also compared the colours with my aging Nexus 7, and that looked much better too, as do my various monitors. I've RMA'd the device, and will give one more a go before deciding whether to keep it. Such a shame - one of the main reasons I went for a 2 rather than a 2 XL was the supposedly better display... And if only Google would allow us to calibrate the colours ourselves, I could probably have resolved the issue myself.
Color calibration is indeed terrible.
Comparing it to me previous phone, google pixel XL. It makes some colors fade in such a weird and ugly way.
I cant stand it
As much as I love my phone, I have spotted a few things that made me question the phone or Huawei.
First of all, I was playing with the three rear cameras and noticed that when I hovered my finger above the topmost camera (I think it's the 40mp one) or covered it, my finger didn't show up. Is that supposed to happen?
Secondly, when I take a picture in complete dark, there is always some noise present.
Thirdly, the screen has a gradient hue, darker on the left side as compared to the right. I have attached an image in this post. Please check for the gradient as I seem to see it on my screen. This is clearly obvious in a complete dark room.
Please check your phone and let me know if you're facing the same thing. Thank you.
The top one is used when zooming (5x) i think.
But funny enough the live view seems to not always use the same lens as the lens the photo is taken with.
If you zoom 5x and cover the top lens (or even when its dark ?) the live view switches to the main lens.
Sometime you can catch a glimp of your finger just before the switch happens.
And then when you take the zoomed in shot with the top lens covered you get a black picture, although the liveview shows an image.
I tested this in a fairly dim living room, so your mileage may vary if you test this in a bright office or outside in the sun.
For your noisy dark pictures. If you take a picture in a completely dark room (covered your screen ?) then the ISO is probably cranked up to the moon. So your going to see noise.
Maybe try in pro mode with a sane iso and exposure time (to avoid noise and hot pixels) and see how much noise you get then.
Yes, it seems so that when I zoom while covering the lens, the picture comes as the lens is covered. Thank you for clarifying that to me.
Can you please, if you don't mind, clarify the gradient hue of the screen? Or is it just mine? Thank you.

Others have answered your finger question. Not really sure what that point was about anyway?
Re: noise. What were you expecting? This isn't a full frame DSLR shooting raw. This is still a tiny sensor (just less tiny) with a highly compromised lens (miniaturisation comes at a cost). However, it is in my view head and shoulders above any other smartphone for delivering photos in poor / mixed light and at night when hand held - CM1 & 808 still beat it easily when on a tripod or similar.
Re: the screen. There will always be some gradient. If it's bad, I suggest you talk to Huawei or your provider / retailer's support and get a replacement. But since you say you only see it in a completely dark room, I can't imagine this is worthy of replacement.

It's my first oled phone so i don't have any reference on how good oled is supposed to look in very dark rooms.
If you can only see it on dim images in a dark room then your probaly noticing the "mura effect".
I cannot tell if your display is particulary bad or not. But i to can detect it looking at a uniform very dark gray backround in a very dark room. Under minimal light conditions i see no problems.

The top lens is the tele lens. It only has 3x zoom. The 5x zoom is a hybrid zoom where it uses both lenses.
Is there a screen protector on this phone that I can't see or it's just grainy? I haven't seen a grainy phone display for years, I know it's pentile AMOLED and only 1080p, but grain is really obvious lower brightness on white/light backgrounds

I also see a grainy display, sometimes it's bothersome especially on views that have same solid color. Coming from an original Pixel XL that AMOLED screen did not have a grainy image.
Yes gradient/blur pictures/wallpapers look terrible on this phone ?
No such grainy display in November. Bestbuy retail.
