I have my pixel 4 xl for a week now and Yesterday I noticed what seems like a bug with my display on the phone. When I have a black/dark blue color displayed on my screen and i scroll, the black/dark blue color will scroll but with a small delay (maybe something like 0.2sec). I have this bug at least on YouTube and twitter but I will check if this bug also occurs on some other apps. This is not a very annoying bug but now I only see this when I use twitter :crying:
This bug also appears with 90hz turned off.
Edit : this bug only occurs on twitter when I have dark mode turned on.
This is common with AMOLED displays when scrolling on a low brightness setting. It's completely normal, the display is fine ? turn up the brightness and you will see it's fine!
Yes the black bleeding is common on OLED while in lower brightness. And while the Pixel 4 XL has it, I've compared it side by side with my Pixel 2 XL and now that was horrible. The length of the trail was so long and took longer to "bounce back". Dark scenes and colors look way better on the Pixel 4 XL as I can actually watch I'm the dark with brightness set to 0%. On the Pixel 2 XL it's just a black mess and would have to go to 30% or so to make it actually viewable.

It's known as black smear and it happens to all OLED displays at low brightness when there is fast motion.

I've just noticed a white pixel when i use camera in low light contition. Is it normal for this device?It's not a lcd screen defect because if i zoom the white pixel moves itself. If u want to test it simply cover the lens and see the image on the screen
This is normal. Many people have reported this. I knew about 1 dead black pixel. Having just tried pitch black camera I found 2 white dead pixels. Nothing to worry about, apparently the majority of devices have them.

Ah ok, thanks! Iwas going to send it back ! However the pixel appear after few seconds and not just when i open camera. I notice it is barely blinking...
However lcd is perfect...
The white pixel appear only form 400 to 1600 iso
Anyone noticed this issue?
i noticed it too, a green pixel,that is visible or not depending on the visual angle.. absolutely normal for that kind of screen

It isn't display issue it appears only in camera mode above 400 ISO and it's noticeable in very low light conditions
Hi,
Has anyone notciced un-even brightness across the screen at low light levels (for darker colors)? I thought it was just the nature of these OLED screens, but I don't see this with Galaxy Phone with similar display type, so I'm wondering if I just have a defective unit with bad display.
To test it:
- Do this at night (when ambient light is fairly low).
- Lower brightness down to the lowest setting (turn off auto-brightness)
- Open Chrome browser, and close all tabs, so that you get a blank dark screen with just the "+" icon. This leaves a dark gray background, just enough to notice if there is any uneveness in brightness.
On my unit, I see about 3-4 inches of bands/streaks of darker areas at bottom half of the screen. If I rotate the tablet, the darker areas stay in their physical location (so these bands become vertical instead of horizontal), so I know it's not a software issue.
I have a couple of weeks left before I need to decide on whether to exchange the tab, so would appreciate if anyone can help me verify if this is normal thing with these screens.
Many thanks, Tony.

I have notice a similar thing, mostly on gray - dark gray backgrounds, and not necessarily at lowest brightness (low enough though). I wanted to check about it on a couple of devices on display at retail stores but it's hard to test there.

Hi tonyc1,
Having had 4 of these I can confirm that this unevenness is normal on the 9.7" screen but was not present on the 8" model.
I went through 4 to get one that was reasonably even, 2 of them were pretty awful to the point that the greyscale was all over the place.
The unit I settled on has a slightly darker band in the middle of the screen and a slight darkening at the very top.
I owned the original tab s 10.5 and have to say the screen on that was more even and detailed, I prefer the former factor and speed of this S2 but the screen is a step backwards.
Hope this info helps.
Cheers
Thanks for the notes and confirming this is a somewhat common issue. I guess I will live with it for now..
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
Hi
I just received my Redmi 4x. While I tried different wallpapers I noticed a slight green tint on the lower border of the display.
Further inspection showed a visible green coloration on the lower portion of the display. The brighter the display gets, the more visisble it becomes. I don't care about the slight light-bleed on the top or bottom left.
You can find some photos I took.

Of course I don't watch black images at maximum brightness all day. This scenario was chosen for the purpose of illustrating the problem.
I wonder if the display of my Redmi 4x is an exception or the standard.
Thanks for your participation.
I have this problem also. I am using my 4x for 5 months already, and I always use adaptive brightness, but still I got back light bleeding
After lots of research, I finally found a solution, but its temporary.
Download & Install ScreenDimmer (Dims Notification Too) By Etsang From Play Store.
Keep the auto brightness off, and device brightness @100% (Or Above 50%), install app, give permissions and change brightness from app according to your usage, thats it.
I think red tint is a software bug, not a hardware, because at last the motive is to decrease the brightness (dim the display) without red tint. App is also doing the same. The only difference is it has no red tint.
This works but if advise against using it. It records your inputs.
More to your point of it being a software bug, I agree. I wats always under the impression that they could fix it by adding blue in software based on the light sensor input. I noticed that if you put your phone in grey scale (in notification tray) that the grey for the icons in the tray that are toggled on, are actually grey while the other have a red tint. Normally the toggled on icons are blue when not in grey scale. The fact that it can show grey properly under these conditions as well as the one you described shows software could address the issue.

Oh wow it works but im gonna wait for asus to fix it.
Yeah, actually the brightness mechanism of oleds and LCDs is different, lcds just have a backlight led that would get brighter or dimmer pretty straightforward, but OLED's case is different, getting brighter or dimmer means showing different frequencies of the same color so our eyes can see that color brighter or dimmer, thats why when you turn the brightness of an oled panel down you still dont feel the way you do with a lcd
Long story short, this tint issue is most probably caused by wrong calibration of different brightness levels but still, i would take my hopes up with asus...they dont have a good history of customer support at least in their mobile phones section
Btw, thanks for the app and thumbs up
happy to hear this is a software issue. I am sure Asus will fix this with an update.
I knew this was a software bug long time ago. Since I noticed even night mode did same problem too. That's who I found out this is software defently.
