Screen vertical lines aka banding - Xiaomi Mi 8 Questions & Answers

So i got my Mi 8 since Friday, after browsing on Twitter with night modus on in the app I noticed some vertical banding or screen uniformity.
I downloaded a oled test app and it was clearly visible at 10%.
Does anyone got the same issue on their Mi 8?
It is only visible in the night when it is dark outside and when in low brightness.

I had it ( but less intense ) on my SE only on the XDA Labs with their dark background on while the brightness was set to lowest. But even then, it was barely noticeable.
You can always turn the brightness up a bit to get rid of it, right?

Is your Super AMOLED screen still working properly ?

hi guys,
Is your Super AMOLED screen still working properly ?
how long did you own your phone ?
Have my phone for 8 or 9 months, still going strong, nothing funny and no burn-in.
I use the screen mostly at low brightness.
I have the idea that JVH/2.3.3 has lower brightness, or it is just the brighter days in summer. But it is not burn in as there is no pattern.
Works perfect here.. No issue at all after 8 months. ther eis 24 months warranty so.. got some time for it to get crap and turn it in if it does. =)
All good here. 11 months, no burn in, no colour problems. Generally use lowest brightness settings. Perhaps flashing roms/themes on a weeklyish basis, helps prevent burn in.
Of course, why do you ask?
As far as burn-in (burn-out) if I display a solid blue screen I can see where the AM/PM used to be (before I turned the clock to 24hr) and some small 'smudges' where the other status icons are. Not a big deal.
Different themes would probably help, especially if there was less blue in the status icons (green or orange instead of white) since it burns out faster.
Time burnt in .....bought it like that

status bar and time burnt in when displaying on white screen.. bought used though.. also keyboard is shown very lightly.. but doesnt bother me much though..
I've had mine for 10 months and so far no burn in.
I'm interested to know though, what causes the burn in's?
I've had mine for about 10 months, medium brightness most of times, sometimes max brightness.
Clock is a little burned in screen and sometimes I can see the swype keyboard keys on very white and bright backgrounds.
about ±7 months already...still nothing weird ... still no screen burn in detected.. and nothing unusual...
when stay in house/office = lowest brightness... when outside/driving = maximum brightness..
I don't use brightness. Screen is practically brand new. Screen protector since day 1
Fasty Captivate
I think the app, NoLED causes burn ins.

Used for about an year now. Mainly auto-brightness all the time. Mostly portrait mode. With white display occasionally I may see taskbar contour on the top. Not seen when watching videos in landscape mode.5 star for this display after heavy use.

The time is burning in on mine, visible barely only with blue screen. 5 months.

Unlikely. The notifications appear all over the place and move frequently specifically to prevent burnin
13 months
auto- brightness
looks completely fine to me
Having my SGS for 7 months now,no reported burn in or screen problems.! The phone is a beast.
1 year now,no problems at all
How long do you thing that Amoled screen will last ?
i have mine just over a year now and like others I have burn-in where the notification bar is but nothing else....
Does anybody know if the warranty would cover the burn-in??
13 months, still working great.

Black screen doesn't turn off pixels

Hi everyone, as you should know the Asus Zenwatch 3 has an AMOLED display. From my understanding this should mean when displaying the colour black, the pixels should be turned off completely (like on my S7 Edge).
I was looking at my watch in a pitch black room with an ambient watch face displaying a black background and it appeared slightly reddish. Compared with my LG G Watch R sporting the exact same watch face it was clear the LG had the black pixels turned off but not on my Zenwatch 3.
I've attached a couple of pictures taken with my phone of the Zenwatch 3 in a pitch black room, one with normal shutter speed and the other with a 2 second shutter speed. Evidently the 2 second shutter speed shows that the display is in fact not turning off the pixels. The pics were taken when the watch was charging and in ambient mode with a watch face set to true black only.
Can anyone else confirm that this is the case and maybe a reason why? I'm worried that battery life may be affected by this with always on display enabled.
Lastly on a side note, are the black lines that aren't illuminated something to worry about?
Mine is the same, including a similar set of dark lines. I've seen others on Reddit report identical concerns.

Noticed this too, thought I was crazy lol...kinda waste of an AMOLED screen.
Hmmm ok at least I'm not the only one. Hopefully Asus is able to change it in a future update.
Yeah it is weird, black watch faces aren't truly black. I think they did it so watch faces can blend into the color scheme of the watch, if you notice the color overlay on the app launcher
That's because of auto Brightness. Turn it off. This impacts battery life. I observed this on very first day after the purchase. Using manual Brightness since then.

I just tried disabling Auto Brightness but the red tinge of the black background still exists.

It doesn't happen with me. If I turn off auto Brightness the blacks go complete black. Do you have live display turned on your phones? If so try disabling it. May be this setting depends on your phone. All I can confirm is if I turned auto Brightness off amoled works perfectly.

Not sure what you mean by live display but I just have a stock S7 Edge. I prefer keeping the auto brightness on for my watch so I guess I'll have to live with it.

Live display is when some ROMs allow the screen to have a tint at night time so the blue light from the screen won't affect your eyes at night
Me too have similar display and black line like that.
Glad I'm not the only one with this condition.
I also have those black lines, was about to get a replacement but since I'm not the only one and it doesn't affect overall performance or aesthetics its fine.
Yeah I have also black lines and screen is not completely dark with totally black watch faces
Turning off the auto brightness is not a solution. Its a pain if you had to adjust the brightness all the time

Dirty Screen. Defective?

My new Mi 8 seems to have a defective screen. The defect becomes visible when the screen brightness is very low. Is this normal on Mi 8? Or mine is just defective? I've noticed it yesterday night when using a blue light filter called Night Shift. It's visible specially on reddish background and a blue light filter makes the screen color to reddish. You should also try yours and see if it's defective. I specifically downloaded a black image for a better view and turned on Night Shift with Dark filter and lowered brightness at 1-5%
The point is, what is the point of using the phone at brightness 1-5%?

On Full Brightness…. Auto sensor kicks in by default !!?

If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
@craige
I think it is intended as you see there's a color RED at the far end of the brightness scale, and that's signifies the most extreme situation the screen can go, which in prolonged use may damage he display. But still, it can provide a elevated readability when you are out under sunlight... And return to safe margins so as to prolong the life of the display...

Tint in k20 pro display

Hey guys, hope you are doing great.
I have noticed one peculiar thing, when i sit in pitch dark places with brightness at the end, i face this white issue over my display screen shot attached, it's Google chrome app which showing me these results,(there are many more also)for this to be noticed you must sit in a dark room.
I know it's typical led panel issue and i would like to know if i am the only one?
Do you seriously think we are able to see your display in a screenshot?

If you are in a pitch dark room and see no anamoly then your's display is good. If not you will see a whitish tint over the top area
And btw you can check on your device itself, by just opening chrome(if it's black) and in dark room with brightness as low as possible.

Enable feature in display settings under anti flicker mode to on. and check again your screen in low light conditions.
Yup, that worked, it increase overall contrast for low brightness, is this condition(tint) is normal for amoled panel, or i am just unlucky.
