Hi,
I just got my new OnePlus 6T. My previous phone was Galaxy S8. On low brightness when I scroll the screen I can see huge glitches (dark purple?) when the picture goes from black to color. Is that normal ? I see this only in low screen and dark pictures/objects.
Typical effect for AMOLED screens.
Yeah very normal. The level of black crush etc is good on this screen
The 5T has this effect more than the 6T as far as I can tell. Definitely a normal thing for these OLED screens though.

Yo.
I'm still wondering if my S5 screens is as good as it's supposed to be. I have 2 major concerns, screen uniformity and purple trails.
I come from an ancient S1, and nothing of this happened. I have attached a single color pic that shows clearly how screen have a soft gradient from top to bottom on my phone. When I put basic colors (RGBYWB from test modes or apps) nothing of this is apparent at all, and screen looks gorgeus, but this color and some other grays show what I'm talking about. I would be grateful if you load the pic in full screen mode and tell your impressions. Offscreen shots would be welcome too.
Also, about the purple trails when moving on screen pitch blacks, it affects every screen or only some unfortunate ones? S1 never show anything similar. Max bright reduces it, but nor completly.
Greetings.
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
I'm not sure if I'm the only one, but when I browse Reddit Sync on AMOLED mode on a decent brightness, I get minor to severe ghosting on certain images. Its gets worse on lower brightnesses, and I'm not sure if this is common occurrence for AMOLED screens, or if I'm the only one. Thanks in advance.
Link a page you're getting ghosting on so we can test it, also tell us what brightness setting.
I get screen ghosting when the color changes from pure black to grey. Especially when scrolling a black object on a grey background, I can observe the back pixel takes some time to switch to grey.

I get it as well, I think it's just a limitation of AMOLED panels. Not sure if the newest (on the Galaxy S7) have it as well but it happens with a lot of AMOLED panels.
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.
