Not sure if it's visible but I'm fairly certain that I can spot this. Check the attached gif. Notice how the lower three thumbnails lag while scrolling . This thing is slowly making me insane.
Any suggestions? Phone is pure stock, no modifications, miui 11 global 11.0.1.
yes, i can also spot wavy motion when using Instagram in dark mode with brightness low.
the edges of images give some black wavy shades on scrolling same occurs when we use in direct sunlight color are too sharp on full brightness under the sun
I think you speak about the big AMOLED weakness, that's "normal" and can't be fixed...
It's normal for AMOLED displays and VA Lcd displays.
when its complete black pixels turn off and it takes a while for them to turn on again and show the new color
less visible in higher brighnesses
Yeah i have this problem any solution to fix?
Its very simple. Because we have an OLED display the individual pixels can and will turn off to display a true black. But when that black pixel that was turned off needs to change color to for example green, the pixel will have to turn back on again. And this takes a few miliseconds (probably more than 15ms, but thats just my opinion) thats why you see ghosting/trail. We cant do anything about this. Better have true blacks then less ghosting and greyish blacks on other panels like LCD.

I noticed that when I turn my brightness down my phone gets a purplish tint but it goes away as the brightness goes up. Is this because its special type of LED screen or the over saturation of colors?
can you post some pics please?
Normal for AMOLED screens. They tend to get a red tinge to them when they dim down.

Alright I guess the technology isn't perfect yet definently not a deal breaker
I was wondering why the light grey look pink in gmail app
I see it as well. A little annoying, but not a giant problem. The blazing speed of the phone kinda makes up for it.
does anybody of you also noticed this thing: http://www.nexusoneforum.net/forum/nexus-one-tech-issues-bug-reports/1199-amoled-display-issue.html ???

I did notice this as well. Some of the red pixels on the edges of text seemed to have drifted a little too far from the body of the glyph. I actually thought the same thing as this poster - sounds like they need to tweak their "subpixel LCD text" algorithms to match the different layout of the OLED screen.
I'd add to his analysis that subpixel LCD text algorithms typicall employee adjustments for the non-linear response of the pixels (steps of brightness near the dim end of the scale are not the same perceived size as steps of brightness near the bright end of the scale) and OLED may not only have different non-linear response, but it may have different response in each of its R, G, and B pixel elements...
This all should be tweakable in software and is bound to be improved as OLED screens gain popularity.
After a year of usage, through using the antutu test app for LCD I noticed that the pixels on top edge of the screen are brighter than the rest. It's probably because of the black notification bar.
Can other users with super amoled NS check this and see how their panel holded up? The best way to check it is with a plain gray or blue image.
Thanks

I've the i9023 myself, but current (possibly future, too) OLED panels degrade unevenly. Whites and blues use the most power and lower the brightness after prolonged use more so than reds and blacks (with blacks effectively turning off the pixels and draining little to no power and don't effect brightness).
These kinds of effects are likely going to be more prevalent now that some years have passed since the first OLED displays have appeared. For comparison, LCDs use a backlight behind the screen which uses the same amount of power between white and black, though blacks look a little grey. As a result, there is even brightness fade.
When in low brightness the blacks get jelly like stretching effect when in motion. I notice this all the time, with text and whatever. Most noticeable if a picture has something dark surrounded by bright area, scroll up and down and see the block stretch like rubber. What's up with that and why haven't I seen it mentioned in any review.. Very obvious artifact.

I have this same problem. Anyone have any idea what it can be?
You're seeing the pixels turn on and off as they turn off for black. All amoleds do it. Usually more noticeable when the brightness is lowered and it is white on black.
There is no pure black color. Black pixels aren't off. Later I will try make some photos to show this. I don't have this in S5, where black and gray colors are perfect and looks like in every amoled LCD's should be.
on older devices(saw this with the note 2) black would be near-black(leaving a slight grey/greenish glow only visible in complete darkness)
with the note 4(don't know about S4/5 and note 3) they decided to enable "true" black, allowing the pixels to turn off completely when displaying black.
switching on/off takes a tiny bit longer than changing intensity, which causes visible ghosting.
this is only noticeable in very specific circumstances, so most people never see it happen.
Black color looks it like with sephia filter. I don't know what it is. I changed ROM-s and kernels, still this same. On S5 black color is beautiful, Note 4 looks terible, especially in dark rooms. See atachments.
I started to notice uneven color or black botches under certain condition
the display look excellent during normal usage
- extreme whites & black are even and look fine, however the problem start to popup at dark grey just above the blacks i noticed a black botch in the lower display part
i detected the problem by doing the following
1- download (Full Screen Color Light)
2- Go to a dark room
3- set the screen color to dark grey, just above the black level
4- set the brightness to middle
5- noticed uneven gray color or black botches (similar to light bleed in Lcd)
Is this normal for super amoled display or should I RMA my device
note: issue isn't noticeable under normal light conditions
please help is everybody having this or should I RMA?
RMA the phone, that isn't normal.
Sent from my Nexus 6P
Not normal, I have seen the issue though from the Galaxy S2, Note 2 and Note 3. Im glad to report that on my Nexus 6P the black is uniform and deep.

Black is deep and uniform in mine too, however the problem appears in dark grey only, as if not all the AMOLED pixels lit all together, or the voltage isn't uniform
making this pattern
appreciate if anyone can provide a picture of his dark grey screen in a dark room
Hey, I've recently noticed small dark dots on my screen. Few of them are in a left corner, but these are only visible in a really dark room, on a really dark grey screen and on the lowest possible brightness. However, there is one dot in a center part of the screen which is more visible than the other ones (it is still visible at approx. 50% (or even higher) brightness on a dark grey screen). This one particular dot is newer than the corner ones. I couldn't find a lot of information about this issue, but from what I've found I learned that this is a common issue with some AMOLED displays. Is it true?

Sounds to me a lot like dead pixels
My Mi 9T also has this. It's not dead pixels, but rather unbalanced pixels due to manufacturing tolerances on (AM)OLED panels. On lower brightness some pixels may be sligthly dimmer/brighter than others as it is difficult to drive an OLED panel evenly on low power. This is also why the screen can seem to flicker on low brightness, because PWM is used the pixels rapidly turn on/off to keep image quality acceptable on low brightness. Without it the artifacts would be even more visible.
Every OLED screen will have this to some degree, but it is more noticeable on non-flagship phones because they tend to get the panels which are not good enough for flagship priced phones.
