So there's one thing I'm not understanding and I think it's a software bug. We all know that what makes an oled screen special is its capability to turn off pixels to represent the black color... so here's the problem.
I noticed that in a certain range of brightness level (around 20% and 35%) the display "turns" into an LCD display because is no longer able to turn off pixels to represent the black color.
I'm gonna attach 3 I took with my brother's smartphone, so about it:
I used a black photo (a completely black one) on my smartphone to show it.
First photo: I was using the brightness level the lower possible. Everything seems fine.
Second photo: You can see the problem, the black is no longer black anymore. It happens when the brightness level is around 20% and
35% (sorta).
Third photo: The brightness is at its maximum possible point and you can see the black parts returned off (it looks gloomy but it's because of the camera).
I have the same, "oreo colorizer" there is a program that forcibly changes the color range to dci p3 , it solves the problem but I don't like the colors when it is active

I have read articles that said using DC brightness on OLED/AMOLED screens can effect colors, particularly at low brightness. How are people finding it? I dont really care if it makes colours "less accurate" as long as they dont look weird
Looks fine to me. Barely can tell the difference.
Working well as described, couldn't tell the difference.
Can someone try to port it to OnePlus 3 / 3t?..

What makes you think the 3 / 3T screen is capable of DC dimming? Can every AMOLED screen support it?
First off, I don't notice any flickering when the screen brightness is low so maybe DC dimming isn't for me. I'm sure someone with a fancy color monitor device will probably post a technical breakdown of how it affects the screen, but I don't see any difference except in one scenario.
In bed I tend to set the brightness settings on the lowest and then turn on nightmode to dim the screen even further. If you have small white text with a black background such as the settings menu or Youtube in dark mode, some of the text fades into the blackness and is unreadable. Images with dark colors or areas will look weird because you won't be able to distinguish them apart.
I tried to take pictures to show a comparison, but the screen is so dim that it doesn't work.
Hello to everyone, new user of the Xperia 5ii and I have two problems
1)Has anyone observed a slightly change in the colour of the screen between 60 and 120hz? It's very obvious if you have dark mode and sit in a dark room. When you toggle the selection on and off, you can easily see it
2)I was trying to upload an Instagram story and the quality drops significantly. You literally can distinguish pixels. It's only on Instagram, on Facebook there was no problem. Also I tried to upload the photos from another device, and the same problem exists.
Any help is most welcome

This is true and if being honest, quite expected. It most noticable when the screen brightness is somewhere 5-20%. You can clearly see it when toggling the 60 or 120hz. The panel itself is great, many oled defects are gone or very minimal. This green tint issue is quite common on other 120hz panels too (mostly Samsung made). That might also be one reason why the new Iphone 12 phones don't have 120hz, too much quality problems.
So yes, there is a green tint. But luckily it is very minor and only on certain screen brightness. Haven't noticed it when actually using the phone.
Not sure if this count as a defect to get a replacement (the replacement would probably have the same issue).
Attached few photos I took.
I have the same issue in low-brightness and 120Hz activated
My note 20 ultra has vague gray horizontal lines when displaying a gray background at the lowest brightness when running at 120Hz but it disappears at when the brightness increases or when switching to 60hz. Is this normal for AMOLED displays ?
I tried doing it on my unit but everything seems fine. Can you send a photo so we can see what it looks like?
It's prominently visible in a dark room
This is when it's running at 120hz
Same here
They all have it. It's the 120hz mode banding.

Same here have u sorted out this issue!?
I'm having the same trouble with my Samsung S20 Ultra as well. Mine wasn't even dropped or had put pressure on the screen for it to be physically damaged. I did, however, noticed the lines appear after an August security patch update was installed so I'm waiting to see if a new system update would fix the annoying lines. Other than that, the phone's performance (battery and processor wise) doesn't seem to have changed.
MY S22 ULTRA, 5 months old, began 48 hours ago to show the background of the lock screen (active display with a black background, in a very oscillating dark green color.
It only happens when the active display is activated, and sometimes inside with a dark background when it tries to adapt the brightness to the environment, it occurs as a kind of almost imperceptible flickering.
Internally the navigation, videos, photos and others are all perfect.
Things I have already tried:
Wipe Cache
Toggle between all screen resolutions and display options etc etc
With the mobile turned off while charging, if I press the power button to see the percentage of charge, that green is also seen.
I was reading that it may be a screen failure, but I still refuse to leave the phone in repair (150GB of internal information already copied), I don't know whether to wait for an update or what else to try.
Any suggestion?
Sorry for my english
I don't have answers for your issue, but I had exactly the same issue. I damaged my screen and it started appearing right after the damage to the screen. I don't use AOD, but mine did the same thing when it was put on charge.... no black screen, just the weird green. I turned off adaptive display and it disappeared. Had 2 updates since then and put back adaptive display and now the green is still gone. Not sure if was an update or the adaptive display change that fixed the issue

I had that problem in my note 8, had to send it to warranty to replace the display circuit and the display because of burn in pixels.

Can it get worse or will it always stay like this?
I just replaced the screen protector and it's still the same sometimes, not always, it seems to improve things but it only appears if I force the situation with dark environments.
How do you explain if it was a screen problem, within the android there is no display problem in photos, videos etc etc
It only affects the active display and while the adaptive display is active, that's why I don't want to send it to warranty so soon, I even hope that with Android 13 it will be solved!
To those who had to change the screen, did it come under warranty and the fault has been recognized without having to pay anything?
Obviously, if it were the screen, it would have to be some sensor or sector of the screen that only acts under certain conditions and I don't know at the hardware level what it could be, if any sensor or sector of the screen is internally damaged, it is very strange.
Thanks for answering.

It was everything free, they replace the display circuit controler, the display and battery (mandatory on note 8 if you replace the display they replace also the battery).
The problem was stable, no true black, allways greenish, sometimes flick and turned true black for couple of seconds and returned to that greenish black. Was horrible, my luck was i had 24 months of warrany and this happend on my 22th month!
Hi, I have same problem for 2 weeks now. Seems to occur when in low light placed and adaptive brightness is on. Did you find solution?
Hello ,
I observe that, my s22ultra in the same conditions (light intensity) make darker screen than my old note10+.
In my old phone (note 10+), the adaptive brightness works very well for my eyes (maybe excluding reaction speed - but never it wasn't too bright or too dark (in my opinion), never had to change any settings.
S22Ultra always make's screen too dark for me (in all lighting conditions) and i compare works of with my old note10+ and approved my suspicion that s22u makes screen darker than note10+ in the same conditions.
In general, the "jump / scale" of switching from light to dark and vice versa is good, but I would have to move the "threshold / level 0" action to a slightly brighter - if anyone understands what I mean - you can do something about it, someone has an idea ? Can I fix working of this function ?
What do you think about adaptive brightness in S22U?
Are you satisfied with its functioning?
See the differences compared to your old phone (what mobile it was)?
Thank you very much for any suggestions
I have two N10+'s and as far as I'm concerned adaptive brightness never worked right. Maybe better than my S4. I disable and use manual control, easier on the battery, display and retinas. It also varies in spite of not seeing huge changes in lighting conditions when sitting, I find this very distracting.
Best practice to limit display on in direct sunlight to seconds not minutes. Avoid using in direct sunlight whenever possible.
I try to limit brightness to less than 50%, 30-40% is typical. As a result after almost 3 years of heavy usage my original N10+'s display is still perfect with no signs of wear.
If I know I'll need to use the phone in bright conditions I will temporarily enable auto brightness sometimes. Otherwise I find it useless and generally too bright.
