Does S3 neo really has an OLED screen? - Galaxy S3 Neo General

I don't remember how it was on original KitKat 4.4 version but neither my last rom (CyanogenMod 12.1 android 5.1) nor the one I installed yesterday (LineageOS 17.1, android 10 which works pretty great) seem to have the ability to turn the black pixels off.
No matter how black the picture is, there is always some light being emitted. Although to much smaller extent than an LCD display. Could this be an software issue or is the hardware just not capable of doing it? It's OLED, isn't that what it's supposed to do? Have any of you guys experienced the pixel off thing?

I noticed the same while flashing ROMs on that thing in the dark. When it reboots you can notice some sort of backlight turn off and when it starts booting that little bit of backlight turns on again. It isn't noticeable at all in daylight. Not sure but my opinion is that it is indeed an AMOLED and the technology is just old for its age and doesn't compare with newer flagships.

But that's the thing, OLED literally is a technology where there's no backlight like LCD. All pixels light up individually. So there's no reason for whole screen to light up when there are some pixels who are supposed to be pure black.
I still think it could just be the software that's stopping screen from displaying fully black colours, but I am not exactly sure either. Maybe someone knowledgeable in this field could clear it up.

It's definitely OLED, the original ROM did not turn off the pixels correctly, but I'm using LOS 16 stable and it does turn off pixels. Also, since the phone is getting old I'm starting to see burn-in in the notification bar, so that definitely confirms it's OLED, just not as good as today's screens.

Interesting, but are you absolutely sure about that? Can you got into a dark room and trying watching a pitch black image in full screen? You can then lock the screen to notice any difference. Because in my experience it doesn't turn completely off.
And I've experienced absolutely no burn in, although that could be due to me not using phone that much but it's still strange.

Yep, just did it to confirm, it's actually black.
Here's a video of it, unfortunately I had to convert to a lower bitrate as you'd be able to see the burn-in on the top where the status bar goes and blacks would be a bit black but trust me, it's absolutely off and it's OLED.

Blacks are not completely black

Previous to my GN, I've had a Nexus One, Nexus S, and Galaxy S II (international version) and on all of the phones black levels were pitch black and no different to the screen being completely off. Despite still being an AMOLED display, it seems the GN's screen can't do pitch black.
As a test, go in a dark room and open the clock app. Long press anywhere on the screen and the clock will go into night mode where it will be a completely black screen with just the time showing. You'll notice that there is a still a bit of light emitting from the dark spots.
A little disappointing... I wonder if this could be fixed in software.

It can do pure black but not everything is pure black. I just rebooted and say the Google boot image. Its solid black. I'm in a dark room now and can't tell a difference where the soft keys end and the case begins.

Actually that's just the clock app, you can easily see that it's an extremely dimmed version of your wallpaper. My wallpaper is this http://cooldesktopbackgroundsx.com/wp-content/uploads/2011/02/34327523.png
and I can easily see the eye in the dark mode.
I don't see how your background could make a difference. Night mode is completely black. Just look at the screen shot.
I can also notice this when first booting up and see the Google logo. It was the same this on two other units that I looked at, so I don't think it's unique to my phone. To truly notice it you have to be in a pitch black room. I only noticed it because I was using my phone as a bed side clock.

The whole point of AMOLED is that each pixel is it's own light source which can be completely turned off. True black was possible on every AMOLED phone I've ever used prior to this one.

That is exactly correct. Fortunately, at very low brightness, my GN does indeed display true black. I have an all black background and if I cover the time, I can't tell a difference between the phone off and on. Keep in mind that true black only occurs under extremely low brightness. Turning the brightness up introduces a bit of light polution.

No, no... I've owned the Fascinate on Verizon and when in complete darkness you can see a little bit of light emitting from the screen. The Gnex just has more pixels so there's probably more light emitting. But the blacks don't seem to be any less black than my Fascinate. When you turn the screen on the pixels must be excited in order to know when they must turn on or off, this will still emit a miniscule amount light.

I'm sorry but you're TERRIBLY mistaken and I wish this thread would get deleted before you confuse others! Night mode is simply DIMMED. It is NOT 100% black, but transparently darkened. There is a really easy way you can see this for yourself, simply turn on an animated live wall paper and go into night mode in the clock. You'll se the moving live wallpaper in the background in the "black" areas. That screen shot you took is showing the TRANSPARENCY where it's black. It is NOT actually black there!!!
The GNEX screen is JUST as black as any other SAMOLED Screen if not even more so! If you want to see 100% black - just boot into clockwork mod recovery! the entire background ther is 100% black and you'll see how inky black it looks! That said the status bar at the top of the screen is also black, and blends right in with the bezel.

What are you smoking? Download that screen shot and check thd color yourself. Its #000000, meaning BLACK. The only confusion is with people not knowing how to go into that mode in the clock. LONG PRESS, not just a simple tap.
Managed to finally find another thread talking about this. Theres even photographic evidence using a long exposure shot.

I guess the comment that there is always a minimum amount of power in even the black pixels could be accurate.

Yes. From what I have read (OLED information, a few book selections, and an interesting patent) sAMOLED displays include what is called "pixel pre-charging".
This is due to the fact that it is far easier to precisely control the pixel, which corresponds to a "drive voltage", when the starting point is a pre-charge. Its faster and more accurate. However the pre-charge causes light to be emitted. There is no avoiding that. As much as people say "my nexus s/galaxy s/galaxy s 2 have pure black", there is NO SUCH THING even on a sAMOLED display. Contrast ratio for the Galaxy Nexus is 100,000:1 rather than infinite.
Hi, just wanted to put this topic to rest.
Was somewhat disappointed in the screen performance of the Galaxy Nexus, coming from an Galaxy S2. However I reckon it is an issue that can be fixed with drivers.
The blacks on the Galaxy Nexus are far from as good as the SAMOLED+ panel on the SGS2.
Here are some pictures of them side by side with the clock app set to night modus.
Not a deal breaker for me, but I hope this is improved in future updates.
PS: Sorry for the big-ass pictures..
my screen is blacker than the bezel..

What is your wallpaper, cause I think I can see it in the second to last photo. Like stated above, the clock is only a semi transparency over the wallpaper. Run a screen checker and take pictures of that black, that would be a better test and example
Edit: in all likely hood its just a calibration issue. Franco's kernel improved whites and colors significantly over stock. Personally, I can see that its not 100% black at the moment, but it is 99.999% black. And 100x better than backlit

The technology switches off the pixel so there is no blacker than that if you are not getting pure black then something is wrong most probably the wallpaper is not really black.

"True" Blacks Smearing/Lagging behind Display Issue

I've notice the screen will smear/lag behind while displaying "true" black (pixels are off) areas of the screen in fast motion (pictures, backgrounds, etc...). I'm sure this is a common problem with this display type as I've read similar things before (purple or black), but wanted to make sure all is well on my expensive new toy. It seems to happen more when the brightness is turned down, but it can also be noticed heavily on gradient backgrounds while scrolling left/right on the home screen. Turning up the brightness does resolve the issue for the most part (you can still see it, but it goes away much quicker), but why is it so apparent on this display versus others (Galaxy S5)? Maybe having many more pixels to flip on and off in the affected area is the cause due to the phone having a 2k display versus the 1080p display of the Galaxy S5. Anyone else experiencing this issue?
I have this issue as well. I have not seen anymore information on this issue anywhere. Have you heard or seen anymore about this?
Yep. I too have the exact same issue. I wonder what the consequences will be when using thw Gear VR with our Note 4... probably weird smushy images I'm guessing
I've had this issue as well. I was on a Plane at night watching Dark Knight Rises. I have auto brightness on so it dims in lower lighting but in that movie there's a lot of dark scenes and you can def see the lag with the pixels during fighting scenes and fast movement.

on the european note 4
i have no idea what to do and i dont want to visit service on the holiday season..... :crying:
Mine does this also. Only when the brightness is extremely low. I think it has something to do with the pixels being "lazy" when the brightness is low. It would be a drawback that comes naturally from the benefit we get with OLED.
EDIT: To sum it up, nothing is wrong, it's natural, just turn up your brightness when it is critical to not have the smearing.

Word. I only noticed it in low brightness levels so I'm not worried. At least blacks are actually black, instead of some purple-ish weird color they had back in the first Note.

Screen issues

I've had 2 Oneplus 3's now, and am now in the process of sending the second unit back for a replacement.
This because the screen wasn't functioning properly, there was lightbleed on both and the screen had a green tint on one side and a red tint on the other side.
Has anyone else experienced issues like this? Is it a known problem, big or small? Or am I just in really bad luck by recieving a bad screen 2 times in a row.
No issue here. Wish the screen was brighter but at least its the same as my g4

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Woah there, I have no idea how it is possible to have the problems I have, I know that with lcd sometimes the glue causes the device to be lit unevenly, don't know if that could be the case, but it seemed a little off. I tested this using this video on full brightness: https://youtu.be/vu0mQa2EpS4
While going from. Grey to black, the pixels should all turn of at the same time, or at least, that's how I think it should be on amoled. But this wasn't the case on both devices.
As for the different tint problem, that does bother me a lot more, reading Web with a changing color if you read from left to right isn't that good for the eyes or at least It bothered me.

Here are some pictures, it's quite difficult to recreate on camera like I see them but this gives a general idea of what my issues were with the first device. The first being the screen tint, on the left of the screen it seems to be more red and on the right more green, while this is a Grey background at about 50% brightness. The second is how the screen is unevenly lit while on a solid Grey low brightness background.

I just watched that LCD test video and firstly my eyes hurt from the bright white light secondly I am quite picky and having come from the g4 which I thought had a great screen (few bleed issues though) I am quite happy. I couldn't see anything at all on my unit like you have so maybe it's device specific?
I have noticed this weird thing though and it's when I use MX player pro to watch films. I have been watching the dark night for like the 20th time on th op3 but do notice the skin tones look a little warm and when i increase brightness it gets worst. I think this is a combination of the pentile display and the AMOLED screen with a lower resolution than we would like. I am sure I remember my galaxy note 3 and wife's s5 looking like this also but could be wrong.
Overall it is strange using g4 then using op3 it's hard to explain but they are just different not just LCD / AMOLED but the calibration also. Love the blacks though it's like the phone is off when the screen goes dark. Nice.

So the screen turned black fully at the same time, well there's a logo on screen, but apart from that all black?
I know what you mean by that, I think thats in all screens, not sure, but I had it in both screens but also the problems occurred on them too, maybe that's a feature, I at least won't mind at night when the screen is that low and a bit more warm toned. I saw it on a selfie I got on whatsapp, at night when I got it, I saw her face normal, but when I set the screen brighter, I also saw that the photo also had a background! which was invisible and dark on the lowest brightness.
no issues

Night Mode *not true amoled black*

I have noticed this issue since two firmware updates but i usually dont use night mode much that is why did not post anything regarding this.
When the nightmode is on and the brightness level is low lets say around 20% , the pixels are not really off when the bg is black (settings menu/qs). But when the brightness is increased above 40% the pixels go off and ive a true amoled bg.
Does anyone else have this issue?

Mine is just simply not true black, but I can only see it when I boost the brightness. But to be fair, samsung doesn't really promise a true AMOLED black as they say it's just so it's easier on the eye at night (dark/low light) ambient. But yeah, it'd be better to have a true AMOLED black in night mode.

Theres no large difference in mah consumption between completely dark mode (pixels off) and dark theme.
To me it seems black parts are true black/turned off. On any level of brightness is the same.
No I think Samsung did it intentionally.. because true black is way more susceptible to burn in.. you can't have UI elements being turned off all the time that would result in very bad burn ins to text and Icones..
Still thay made it dark enough so you won't notice it
And another thing it's the opposite of what you said when the brightest is low it turns off and when it's high it becomes very dark gray technically black but not off.
Also you can't design a decent looking gui if all elements are pure black.
Guys try good lock app via which the notification panel can be adjusted to colors we want

That's not how burn in works. Burn in occurs at the pixel level. A pixel that's on all the time will burn at the regardless of the colors of the surrounding pixels (black, grey, or whatever)

Every burn in is different from another.. basically the higher the contrast the worst the burn is

I think maybe you're confusing contrast with brightness? Again, burn-in occurs at the pixel level, when a pixel cannot return to its initial relaxed state, and is not dependent on whether the pixel beside it is on or off.

I have noticed this issue since two firmware updates but i usually dont use night mode much that is why did not post anything regarding this.
When the nightmode is on and the brightness level is low lets say around 20% , the pixels are not really off when the bg is black (settings menu/qs). But when the brightness is increased above 40% the pixels go off and ive a true amoled bg.
Does anyone else have this issue?

Hello, on my galaxy a50, there is a similar effect, only at a brightness close to the minimum, a gray gradient appears, part of the screen becomes gray and part black. When you increase the brightness to about 40 percent, the color is aligned. At the same time, the black color remains black on the lock screen at any brightness.

Question Do I need to return my f3 because of the screen?

So I finally got my f3, it has been perfect in every aspect, even the screen looks good, but the eye fatigue is simply too much.
I have tried to reduce DPI to minimum, reduce brightness, use reading + paper mode. After these changes it did get noticeably better, but it is still annoying.
I have Samsung galaxy s5 that also has an amoled display, but I don't get the same issue there. Also regular laptop and computer monitors are fine.
So anything to do on the software side to make it better? If not, then what other similar phone would you recommend that has a different screen.
Have you tried enabling DC dimming? For some people (not everyone) the PWM flickering causes some discomfort. I can't see any difference, but I'm glad the option is there.

F3 does not have DC dimming.
The option is there on custom roms, I assumed it was available on stock as well.
Do you know why you have eye fatique? What's the problem?

The text and screen looks somehow muddy compared to LCD screen. Text is not as sharp, or at least eyes feel so, and it is harder to focus to text and objects.
Yes, the screen looks impressive, but can't really use it.
LCD screens are always sharper than their OLED counterparts, but hey there might be a slight problem with your eyes or maybe you've got sensitive eyes. therefore, I can only suggest that you get an LCD device or test an oled before buying. btw I have no problem with the panel even though I prefer LCD panels (no burn in issues in LCDs etc.).
there is still one small thing that I have noticed, there a very slight white line/shadow under the black text and it's more noticeable when the text is bigger like when Im in settings, all the titles or texts seem to have that white shadow under them. Has any of you noticed that? I might make a thread for it later but I just dont care. the screen is waaaay better than my last OLED which was ROG phone 2 with red tint and huge bandings and awful black crush issues...

I personally use Syberia and have no problems with shadows under text.
Thankfully, I don't have eye strain.
Never had a problem on my end you might want to bust some glasses
