yesterday I noticed that the display has like big even stripes, I try to reboot the watch and on black start screen I can't notice them
I guess is a firmware issue, when I lower or increase display brightness the stripes change size and position

Hi, when i turn off my auto brightness and set it to low and the background is white , i can see 2 strange horizontal lines in it.
Should i send to custumer support ? or maybe its normal ?
When brightness is on medium or high it disappears.
Could be because of custon kernel or Rom ?
I take a picture tho show.

I have read that AMOLED screens have several flaws that are imperceptible, an example are screens with yellow
Yesterday night I noticed that black pixels do not switch off completely on my phone. (as they should on AMOLED, right?)
Try it this way:
Set your screen brightness to almost a very low value.
Now look at a picture which has a black background and very little color in the middle etc. The room has to be dark, otherwise you wont see a difference. (You can also cover your had with a blanked etc., just wait a moment, so your eyes get used to the dark environment).
Hide the statusbar, navbar etc., so only your picture is shown (Tap on the picture once in Google Photos).
When you disable your lockscreen and switch the display on and off a few times you'll see that the picture vanishes first and than the display goes completely dark. It looks like a very light yellow back-light.
Another way:
Again in dark environment power off your phone. Switch it back on and watch the bootlogo. The surroundings (everything that's black) is truly black and "switched off" and than some secs before completing boot the "back-light" switches on.
I tried to find a solution for that. The only thing I found is a setting in Kernel Adiutor named "Minimum RGB value" under the screen section which is set to 35. However lowering it to 0 does not work, the value get reset to 35 every time (Higher value does not change anything either tho).
I'm running Oxygen OS 2.2.0 with bluespark kernel + root + xposed (Gravitybox + XInternalSD)
maybe the black is not that black?
edit: just tested with fullhd resolution black picture and red dot pixel in centre(PNG file, not jpg nor bmp) and everything is working as intended - black is pitchblack(same as when u just block/shutdown ur phone)
edit2: i'm not having my reflex by my side this couple of months, but you can check it making a photo in light isolated room with low shutter speed(20sec should be enough, if they really produce light)

Thank you for testing. I reproduced your result with a #000000 PNG and everything seems fine, as long as the brightness does not go below a certain value. Turning auto brightness off and sliding the brightness completely down enables some kind of light in the whole panel.
Could it be some android feature, which put's a light overlay over the the screen image to protect the eyes in low light environments, like these warm filter mods?
Has someone experienced "dancing blacks" with vertical or horizontal scrolling, specially in low bright settings?.(40 or below)
I have purchased an EU ver. Of V30 and i experience this behaviour every time i do scrolling with photos, desktop icons with black contour (like netflix) webpages with black línes or blocks... Or everything containing black colour.
When i move the photo, scroll across website... The part that contains black colour seems to dance on screen, it's hard to describe but it's something like jelly effect, the black part of the object, photo... seems slower and doesn't scroll accordingly. I went to a local store to check it on another unit and discard a faulty one and i saw the same effect.
Regards
That's the feature of all oled displays, nothing you can do with it except changing the brightness to the level it doesn't show any signs of this "violet trails"
i have that behavior too on my H930DS. no solution yet.
The phone regulates it's brightness through PWM, so that you don't have the same issue like on the g flex where the whole display got blurry and grayish when you turned the brightness down. Because the display shuts itself on and off many times per second (222 times according to a German review page), you see that when you are sensitive. Just set the display brightness higher, then you should be fine.
So is it pretty obvious , or does ghosting usually happens on low brightness on every AMOLED display or is this phone only suffering from this ?
(I saw ghosting while I was horizontally scrolling a black picture of a gray background).
Can anyone confirm this for me ? ( Not a huge issue though , it doesn't happen after the brightness is increased)
Try with this image in lowest brightness
Zoom in and move it left and right you will see a trail of weird color trailing the black circle.
its normal for amoled displays
almost all amoled screen leave purple trails when switching from pitch black to some other color pixels.. don't worry about it
Ya when scrolling in app drawer the icons looks like wobbling.
Yes this has been the case in my Realme XT as well. When you have black background in the app drawer and there is any app icon that is dark you see the icons changing their shape while we scroll.
Even in YouTube when you turn on the Dark Mode and there is any video that is pitch black you may see it leaving a trail when you scroll through the feed. This is more often when screen is in low brightness. Is this issue for all other phones with Amoled panel or only with Realme XT ?
Amoled panels basically has the lowest response time in any display technology format except "Ink Display". Every individual pixel lights up individually from switch off (black) to on (any color). Higher the brightness means higher the color spectrum shining into your eyes and thus it let you see no ghosting while at peak brightness. It's still happening but we dont usually see that clearly. Ghosting is very natural phenomenon of Amoled technology. Also these budget Amoled panel tends to big fan of burn out. So make sure you are using live wallpaper that changes or moves (stock one that comes with the ColorOS is good enough).
My s9+ screen suddenly had a lines and yellow color all over the screen and if i move the brightness bar down to 90% it get off lights.
When i play video or be under the sunlight It works fine without yellow color or lines
So i need to make the screen work all the time like i am under the sun light or like i runing a video to get the most brightness
Is that applicable with any workaround solution ?
