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
Hi, I bought my 4X last couple of days.
Im very happy, but now I have one question about display.
I was surfing on the internet and I noticed that on top of the display, there is slightly brown or yellowish tint
Its visible on white or light grey background.
I noticed it isnt on LCD panel becasue when I look closer or in another angle the effect like disappeared.
It looks like sea-bow effect or glass reflection on gorilla glass or something similar but only with yellowish tint.
I red in reviews that the display is in some distance from glass, maybe there is slightly color distortion between glass and display?
My build is 1.1
Did you notice something similar on your 4X? Is it normal? Maybe Im too sensitive?
Thanks in advance.
So, I try to look at the display with white background in the dark room and I can definitely notice sea-bow or reflection on the glass. Its changing the position when I change the angles during the view on display. Anyone notice this? Would be very appreciated.
Yes, i seen to. But it's a very light effect. Is not a problem for me. If you don't advertise this to me I would not seen it.
Anyone other noticed this issue? Thanks.

To be honest, no. I tried to do in your way, I'm not blind, but I simply don't see nothing abnormal in mine Optimus 4X HD.
I have this problem too, and my Optimus 4x is 3 months old. Maybe it is cause by the overheat problem? Since the phone heat up mostly at the top part when playing games or browsing.
It could be that when the phone heats up, the glue melts and the screen gets "dirty" or its because of screen bleeding or because of pixels getting damaged because of the heat.
I also do notice it. Try to look at the phone at a very steep angle, I see that my screen has a blue tint on the bottom and a weird other tint on the upper side. I bought my phone on march 2013 Only noticable on white backgrounds.
Hey guys,
I already mentioned this in the German thread, however it may concern a couple of more people.
I just received my replacement. The reason I ordered one was I got 2-3 tiny little bright spots close to the top right corner on the display. Exactly they are located on the opposite side of the back camera. These pixels are brighter than all others. Though the spots are very tiny you can notice them e.g. if I look closely at the Google search bar on your home screen. It's not that they are disturbing me but I feel on a new device there should not be such issues. You never know how far this is going to get.
So, the today's device is made in Jan 2013 and it has the same spots. I want to ask if anyone of you has the same issue. Just download a pixel test app ( e.g. Dead Pixel Test by Ossibus Software) and look at that area at different angles and colors. I attached a picture to get a better feeling of what I mean.

Sometimes it is better not to go looking for these tiny flaws as often we find them.
LCD panels do have flaws, and a certain number will leave the factory with some broken pixels, some good information here http://en.wikipedia.org/wiki/Defective_pixel
Some applications claim to fix these pixels by flashing the screen with lots of colours, and they seem to work for some people, typically however the pixels are intermittently broken and would have probably just started working anyway!
Manufacturers of LCD panels let a certain amount of screens through with broken pixels simply because otherwise they would be throwing too many away and so their cost would be considerably higher.
I'm not sure if yours are broken pixels however. How are you seeing these? If you are cranking the brightness up to full and viewing a dark colour you can often see tiny pin holes of light, and this is just tiny flaws in the filters which are so thinly applied tiny breaks happen, which you wouldn't see in typical use. You'll never find a screen 100% perfect if it is this you are seeing.
What do you see if you have a dark black background and the phone on normal brightness? Pixels stuck in the "on" position would be very clearly visible. On a white background stuck "off" pixels would be clearly visible, either by showing a tiny black dot, or typically a dot of a different colour.
If you can't notice them in typical use, just don't go looking for them :good:
If they are stuck pixels you have been unlucky, and the only option is another RMA.
Regards
Phil
Had a "hot pixel" almost in the same place as yours when I got the phone is December. RMAed it and the replacement is looking good now.

This is good advice. My last 4 phones (captivate, atrix, gnex and N4) all had some kind of defect with the screen. Captivate had slight burn in, atrix and gnex had black spots that can be seen with brightness on lowest in dark room and my N4 has minor screen bleed under the camera.
Its not hard to find problems with LCDs if you look close enough but none of the defects i had could be seen with normal usage so i didnt bother to return them. There is a chance that you will get a replacement with worst defects not to mention all the hassle of having to do a rma. But then again this is xda where people freak out when they see a scratch on the screen.

Thanks, mate.
When it's black I only see light bleeding from the top. Therefore, they are not dead. I believe, during the manufacturing process a layer behind the the pixel gets damaged. I filed for another replacement. However, I don't think it'll get better.
Anyone having issues with their screens?
I have a red tint near the top right corner.. the bottom left is more bright than the top... it appears like a gradient accross the screen... noticable on dark greys... What should I do? is it a defect or are all devices like this?
Help please. any inputs will be appreciated.
How low is your brightness and is it set to adaptive?

The brightness is set to full, adaptive is off. When set to full, the tint is low but noticable.. when set to 50% the tint becomes more prominent.. and I do not have a problem with the tint.. it is just that it is not uniform.. the top right is tinted while the rest of the display is not.. it is really disturbing when reading an email or typing in landscape.
I think color uniformity issues are quite common on this device. You see some threads on reddit and also here on xda about this issue, most people have some sort of yellow or red tint on parts of their displays. The display of my Nexus 6 is a bit more yellow to the lower right of the screen, however I really only notice it on higher brightness with darker colors in apps like Google Camera or the Material Dark keyboard theme. It used to bug me in the beginning, but I somehow got used to it. I don't see the need for an RMA and get a potentially worse device with other defects as mine is perfect otherwise.

I was thinking the same.. it doesnt bug me that much. but when it comes to keyboard on landscape and specially the google camera dark grey background.. i can clearly see it... otherwise my device is perfect. I read a lot of articles too.. the device is expensive and at such a price getting a flawed display is unacceptable. My main question is are all amoleds like this.. because I had a galaxy s3 and it had a perfect display with no tint. Are all nexus 6's suffering from this problem or is it just a defective batch that is affecting some people. ? My device is just 2-3 day old so I can get a replacement.... although I am hesitant to do so..

I know the feeling, when my device was just a few days old I freaked out like this too. It's hard to justify at this price point but the truth is, no device is perfect. I went through several N5's back in the day and none of them were perfect, most of them had a few dead pixels, creaking body or even dust particles in the camera.
If you say your device is perfect otherwise, won't you rather live with such a small and hard to notice defect than going through a cycle of potentially worse devices? If you ask me, don't go for a replacement. But in the end it's up to you.

Here my vendor is sending me a new device. A box packed one. It should arrive in 2-3 days. The tint on mine isn't noticable when the brightness is above 70% , but I cant use the phone continously at night at such high brightness. Besides the tint is so bugging me when reading anything.. browser, play books.. the uneven color temperature from top to bottom.. it is really annoying and considering that I have paid so much for this I wont settle for this. Lets see how the replacement is, I'll post when it arrives.
Got my replacement.
I got my replacement yesterday. THERE IS NO TINT. BUT. the display has a vertical band that is noticable at time. Well, I can put up with this atleast there is no uneven color anymore. I cannot describe how awesome it feels to use a flawless / near flawless display.
Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.
same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.
Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.
Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge
Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.
I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.
Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!
Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.

I have a Note 9 now too and while it's not perfect it's one of the most even oled screens I've had when it comes to uniformity.
