Note3 AMOLED Screen Quality *edit: tested 6 devices so far*

hi,
i just started this thread to get your opinions regarding the display quality of the note3!
i have to admit upfront that i'm a hypocrite when it comes to amoled screens, so far i had to switch all of my amoled devices a least 5 times until i got a unit which satisfied me. done this with the first note, and also with the second.
as far as i can say the screen of the note3 is the best i've ever seen (by far better black-levels as note1 and note2), although i also identified a few flaws as well:
the color RED has very bad viewing angles: when tilting the device a little bit the color gets orange immediately.
try this by enter *#0*# in the dialer, and click on "red" then tilt the device. let us know how "your red" is, thx!
the gamma of the screen is totally screwed: can see down to "1" in gammatest.png:
the disadvantage of this is that you are actually able to see dark grey screens which you should not.
on the left side of the screen border there is a small strip which has also more gamma then the rest of the screen, in menus etc.
this is clearly visible when its dark around. also only visible when at least a little grey is to display, pure black is ok!
this week i will test one or two more note3's, just to have a comparison and to determine if the quality spread is as big as with previous devices. for note1 and note2 the differences between devices were really huge. some screens were near to perfect, most of them had flaws with color unevenness.
what are your impressions?
and: do you care?
regards,
markus
edit 03.10.2013:
just got my second note (this time from amazon.de): the screen is considerably better!! the "more gamma" strip on the left side is non existent on the second device, in gammatest.png the screen is much more uniform! also the red viewing angle is better, it still fades to orange when tilted, but not as much as with my first device!
conclusio: the big differences in screen quality are still existant, it's still luck of the draw if you get a decent one or not...
also the general build quality differs: on the second device the pcb is not exactly in the middle of the casing, the camera hole is not centered in it's protrusion, and the power button extends a little more out of the casing.
again, i may be a "little" freaky about this things, but for > €700 I want to have a decent device!
screen quality is very important for me, because i read a lot with the device, especially in dark environments where the left gamma strip i mentioned was really annoying! i also showed this to a few colleagues of mine, and they agreed.
edit 04.10.2013:
another finding: when CPU load is high, the brightness jumps between a lower (darker) and a higher (brighter) state, even if brightness is set to manual: both devices show this behavior, although not exactly identically: my first device needs more load to start with this (it takes longer), the second one starts the dimming relatively early.
how to test: load a stress test tool (cpu prime benchmark from google play) and let it run, set the brightness to manual maximum and wait.
you will see that after a few seconds the screen will go darker, and will switch between this states. this is independent from the brightness level, it is only better seen at maximum!
i guess this is some power and/or thermal limitation (when more cores are under heavy load), it would be interesting how this kicks in in summer when ambient temperatures are higher...
edit 25.10.2013:
just to let you know: i'm now through 6 devices, all of them had display flaws in terms of uneveness.
a issue most of the devices suffer is the lower dark half of the screen: on 4 of my 6 note3's the lower half of the screen has been signifcantly darker then t´he upper half,
one had a very bad gamme increase on the left 2mm, one had a bad gamma increase on the top 2cm. 4 had a warmer white, two of them were more cold (more blue). could be due to missing or wrong factory calibration...
what is gone is the "blotch issue" i had with sgs2, note1 and note2, and: black is now really black!
but on dark grey levels the uneveness is clearly visible, look at the attached "gammatest.png"
this shows the lowest grey tones. and should be a very visible gradient from top to bottom.
go in a totally dark room, open the pic, zoom in max, and navigate to the top left corner. then pull the
picture down, and look how the numbers fade. for example: "6" should be at the same brightness level on top
and bottom of the screen. it definitely is not...
go out and test for yourself, and post your findings!
Hi there, I should be receiving my N3 next Wednesday. Are the blacks the 'true blacks', as in taking the phone in a pitch black room and blacks cannot be seen?
Thanks

OLED screens are the only ones I know of that can get true black. With OLED the pixels make there own light so no back light is needed, thus black pixels are not being used at all so a black image has a nice inky black color. You notice it the best when you have a colorful picture with black in it.

sorry, but this is a wrong statement. all amoled screens so far were NOT totally black, even if you displayed a totally black image! the reason is that if the screen is active the display controller is powered (which is the case when displaying a black image, and not if the screen is "off") which can be seen as a faint and VERY dark glow. you can only see this when the room in which you are is totally dark, and your eyes had time to accommodate. to make it worse: on all AMOLED devices i've seen so far there were patterns (like hair lines and blotches) in this grey glow, due to the manufacturing technique used (lithography).
see for reference:

and so on...
so the question of cd993 is reasonable!
answer: note3 is the first device where i cannot see this dark glow, even in a total dark room! so a big improvement on this side. not sure what they changed, but the glow is definitely gone!
Red turns orange here to, but it doesent bother me as the screen is nice overall. Much better than my note 2
Red turns orange when screen is tilted, yes. Black are true blacks in Note 3. If you go to a pitch black room, and display a completely black screen in Note3, the phone will blend in and disappear.
Thanks guys, cannot wait to receive my device!!

Please make a quick guide of what to test and what to look for on a new note 3, in order to decide whether or not to return or warranty claim. Basically: On arrival, what would you check for, and what result would make you return it and get a replacement? How much of any issue would be ok for you to keep it..?
N3 screen : brighter and look better than Note 2 and S4 but still can not compare to the best IPS screen about white color

You'll do that with any Android phone whether LCD or AMOLED because their screens aren't individually calibrated (iPhone's are). So there's some degree of acceptable production tolerances that means all built won't be identical. So whatevery you went through before you'll go through again with the N3.
Oled = true black
LCD = true white
Sent from my note 2 ya bish!
Today I got my N3 and all I can say its SUPERB!!! Abs everything
My only concern with AMOLED is the blotches that show on a grey screen in a dark environment like the first time I noticed it using Facebook. I had to replace my first Note II and even the second has some blotches but not quite as big and bad.
I've attached a grey background for your convenience to see if your AMOLED has blotches. You'll need to be in a dark environment like reading at night without the lights on (simulate by going into the bathroom and turning off the light).

My ps vita has those blotches really bad!
You only see them in a pitch black room but I think they are the same thing.

Pointing out to OP that the leaking light on the Note 2 (and s3) is extremely reduced in the S4 and Note 3 - you should not compare the Note 3 with the Note 2 in that aspect.
Black wallpaper on n3 = better battery life then?
Other than seeing imperfections in impractical situations, is there anything about the display that is actually bad in normal use? I mean do you see whites on this phone and think, hmm that's more of an off-white or is it like so small in difference that you need a color spectrometer to prove that it's not "true" white?

I know what you mean. I had that on my note 2. Not so on my note 3. When I open black screen in a pitch black room, the phone becomes completely invisible as it blends in perfectly with the dark. And yes, I'm not exaggerating. It's the deepest black I've ever seen on any display, it's like the phone is actually turned off.

Hi Guys!
Need info about PURPLE SEMARING. Does the Note 3 has this issue? Because all the S4 has this semaring issue although it has a pitch black. Please confirm this purple smearing. If it's totally pitch black and without smearing it will be the perfect screen out there
Thanks guys! :highfive:

[Q] A part of my screen is slightly brightest than the rest

Hello,
I have a few days with my device and I love it.
Yesterday I updated my phone using Odin, but my phone was in a Flash mode for about 1:30, I kept rebooting it to avoid any burn in.
Today I noticed my phone has a part (like a band) of the screen that is brighter than the rest of the screen, only visible on gray background and with low screen brightness.
Is this normal in AMOLED screens? Doesn't seem to be burn in at all, it's just a brightest segment of the screen. Not sure if this is normal in AMOLED. Overall, I love the screen and colors, just want to know if this brightest band in the middle of the screen is something normal in this kind of display.
Thanks!

I think all have this and uneven whites but it's the luck of the draw how severe you have it
Same here I put it next to my s5 and the s5 is perfect on mine it's brighter at the bottom very frustrating

I have this on my S8+!!! It's terrible. It's getting darker as time passes.

Display issue with S7?!

Hi, I bought S7 two week ago, and I notice that my phone have some issue with display on dark gray color, for example when you close all tabs in Chrome browser (Merge tabs and apps and home page have to be turned off). Problem is uneven color, like in the picture below. In real isn't that noticeable as on picture, but I can see it. So I just want to ask if anyone have similar issue an what do yu think about this?
up...
Faulty screen.

i also noticed that i have some gray or black dimmed spots on my screen ...i had similar problem with xperia z5 but with the z5 i had white spots instead grey ones LOL looks like these days buying a phone is like lottery
Got the same problem with my first 2 units, I only got an acceptable screen uniformity on the 3rd unit. You should send it back to have it replaced. Screen uniformity on gray and white backgrounds is a known issue with some amoled screen especially with the high density panels.
I live in Serbia, and here is very hard to get replacement unit. And in 20 days I have to move to Malta and I don't have time to replace phone even if they want. But, I'm not only with this issue and isn't that terebel... but I compared it with my previously S6 and he didn't have this problem...

Huge app selection on outer screen

Hi everyone so I've noticed my edge panel app selector is huge on my outer screen I've seen pictures and videos of other people and theirs is properly scales to the screen. Would anyone know why mine is so big? I'm running the US unlocked variant with 400dpi on outer screen and 900 dpi inner screen.
Screenshot
It looks normal. Just Remove some apps if you want a single row.

It takes up to almost 50% of the screen. I've seen others where it looks like my S20 Ultra which is just a small section on the right.
You are comparing to different devices and screens..

I've seen other galaxy fold 2 screenshot where it is scaled similar to my S20 Ultra.
Sorry if I didn't word it correctly.
Without pictures for proof. I don't believe it.
Looks a lot like mine.
Same here
Next Launcher 3.7.3.1
I just can't believe this OLD launcher that's a bit buggy on 8.0> is actually usable on Android 10 on the Fold2 (with the same and a couple more quirks as my V20 on 8.0).
Looks like it's normal. I wish we could scale it to our own liking. Thanks guys.
The issue the OP is complaining from is actaully due to the fact that certain display minimum width values (above a certain threshold) would cause some widgtes(e.g device care widget) and icons to go large (i dont know wheather it's because it triggers tablet mode or not). Try to set display zoom to default values in the settings and it should return to the correct scaling designed natively.
Changing the Dpi doesn't change the pull-out menu..

Question Galaxy S22 Ultra green tint when looking from the top (bad viewing angles) Problem

My Galaxy S22 Ultra has a really bad color shift when looking from the top. The screen gets a green tint even when you are looking only a few degrees from the top. You can see it here:
https://imgur.com/gUDFh2Z
(It's more apparent in real life than in this picture)
Looking from all other angles than the top the display looks fine. But it looks like the screen is shimmering if you turn the phone a little. I tried to caputre the effect on this video:
https://imgur.com/e7PghPU
I have my display set to WQHD+, adaptive refresh rate and vivid mode. The brightness when I took the photo was around 60%, but the problem occurs at all brightness levels.
My previous phone, the Galaxy S20 5G, doesn't suffer from this problem. The screen does not change color at all when I look at it from a slightly different angle.
https://imgur.com/H2S3KwV
So I'm wondering if other S22 Ultra users have had the same problem or if my phone is just broken and I should replace it?
Thx for your help
I have to admit I don't "see" it. I think the brigthness and the rounded edges may cause a somewhat "dark" line depending on viewing angle but I don't think it's a defect.

I also do not think that it is a manufacturing defect because I checked all the devices around me and they were the same degree of green, do you think it is because of the new type of glass Victus 7 Plus
I had the Note20U and it was common to see that on the edge on white backgrounds, which is why you can't see it in "flat" phones like the s21U and S22 non ultra series. I think the same applies to foldable phones when viewed in a certain angle with white background.
Mine does the same if I look at the screen from a very off angle. Had not taken note of it though until you pointed it out. Guess I was just not expecting a good quality view from such a steep angle. Just out of curiosity, I looked at a similar angle at my computer screen, TV, Kindle, Tablet, and an old phone. They all have various degrees of imperfect display when viewed from a steep angle although the shift in color was most noticeable on the S22. But still, I guess I would not consider it a defect.

I am a user of all versions of Sam and all devices have different Vision angles, but the Galaxy 22 Ultra is annoying and I expect because of the 1750 nit brightness
Mine has the same issue. I bring it to the Samsung center. Their demo device was the same. So i assumed it wasnt the manufacture defect. And most of the time, no one will look at the phone from the top down like that. So that was not a big issue at all. We should be thankful that the grey uniformity is much better than those from Sony or LG. The grey uniformity in low light on those phone were abysmal
It's not a manufecture defect, this is "normal" to curved screen on some viewing angles, same happens with the flip and the fold and the N20U, the flat S21/S21+/S21U/S22/S22+ do not have this issue as there is no curve

This is a problem, which is defined by the bad viewing angle, and it may be worse than the uniformity of the gray color, which may appear only in gray and in weak lighting conditions, but this problem is annoying because it accompanies you with all light colors, and it is a problem that appeared in the first batches of the Galaxy S21 Ultra and was referred to by some reviewers and it was widespread in the days of the Galaxy
It's faulty. My 1st S21 Ultra behaved the same way. Meaning it had a very aggressive color shift with the slightest of viewing angles. I understand OP fully.
I have the same green shift as well on my S22 Ultra. It was not there on my S20 Ultra. It is more likely due to "improvements" in the screen, what you gain, you lose elsewhere. While the green tint is there, it doesn't affect me as I look at my phone directly. Others trying to peep over my shoulder can enjoy the green shift.

Return it and get a phone from a different manufacturer or stop worrying about it.
