Hey,
i just got the Xiaomi mi8 (Global Rom, MIUI 9.6) and noticed a thing with the display. If the brightness is under 40% (lower the problem gets more and more visiable, gets really bad at 10-15%) the black is starting to smear if next to a grey color. If i move a black part surrounded by grey over the screen the black smears into the grey. I also noticed there is a slight color gradient from left (dark) to the right (getting brighter).
I contected the shop i bought it from and they said they never heard of this problem. I googled the problem but got no resaults. The shop send me a new Xiaomi mi8 but guess what, the same problem occured on this new device too.
I tried to record a video but its really hard if the room is dark and the screen is at a low brightness but maybe you can see what i mean at the edges of the black parts if you look closely.
mi 8 screen recorded with a camera:

I made a test pattern and attached it to this post. Would be really helpful if somebody could check this on his/her own mi 8 and leave feedback!

Really? Hmm, than i have to look for a device with a good old LCD panel.
Absolutely normal, my old s7 did this too, its due to the fact that pixels are turned off when displaying black and it might take a fraction of a second to turn on resulting in this smear. Happens to all oled displays

Hi I have a small problem with my galaxy and I wonder if it is a common thing or is it a sporadic case. I recently took my galaxy in assistance for the replacement of the screen (between lcd and capacitive glass had a hair) Once again after a while 'I realized (I think that there is a problem from the beginning) that appeared on the display strange signs. Initially I thought it was a lcd problem then I tried to shift the LCD image and saw that signs remained fixed as if they were between display and glass. I brought the phone back in service but they said there were no defects. For sureness (they were very nice) they showed me another galaxy just out of the box and presented the same peculiarities. It seems to me (but I'm not sure) that the first galaxy that I had not had this feature.
If you want to help me try to manually set the display brightness to low and pull down the curtain of the notification bar, or choose a dark gray background and gimme an answer.
thank you
i attach a photo
anyone?
I saw that many people have downloaded the image.
thank you
Can you explain what is so peculiar about it ? I dont see anything wrong with that image . Is it the three orange color curved lines ?? (though that looks to me like a reflection of something).
Are you talking about the red haloing effect around the white text?
Apart from the orange claw 'reflection' in the top right there is nothing discernible about that image.
orange signs are camera lens reflection. I talk about grey zones of images. If you watch closely you notice that some grey pixel zones are different from other. With a kind of green blur.
thank you for your answers
Is this what you are concerning about?

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
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
Yesterday i got a mi 8 6/128 and i found for now 2 issues till now the first one is that when i want to take slow motion video it flickers a red light like hell, the second one is the screen itself when holding the phone and looking at it straight in front the color of the screen seems a bit yellowish also the colors are a bit under saturated when i see the screen from a side view even from bottom or from any side the colors pops out and the white backround is white as it should be i think it has something to do with the front glass that covers the panel and i don't know if there is a way to fix that, i use cool color reproduction on settings but it still annoys me.

Hi,
Got a new Moto Edge 20 Pro a couple of weeks back.
The display at low brightness has very noticable Faint White Lines and the display looks grainy, like newspaper texture almost like the Kindle Display.
At darkness, when the display refresh rate is set to auto, I can see the grainy noise and the white lines change when I touch the display.
Grey and White colors arent Pure Grey and White. When I use pwmfree 1.3 or OLED SAVER app, the white lines are almost gone (not entirely gone) and the grainy texture / noise increases.
Any idea whats going on, whether it is a software or a hardware issue ?
is there a way to get this fixed ?

The noise on the display is the nature of OLED displays. Or at least the one on this phone. I have a regular Edge 20, but they have the same display anyway. Same issue you pointed out: grain with certain colors and at lower brightness. And yes, I do get some vertical lines at the bottom of the screen. It's not defect, it's just the way it is.

I had an iPhone12 before this and that too had an OLED Panel, and I wasnt able to see anything like this.
And the Noise is not consistent. It's pretty freaking uneven and Its a total mess. To see the Noise completely, just open a 2% grey image or something and observe it. It's pretty abysmal. No way OLED displays are this bad.
I just think that Moto has crapped on its customers with a defective batch of Displays.
Also the situation gets better when you use pwmfree app.
The panel's gray uniformity is pretty bad. Im suspecting if this is a case of banding/dirty screen effect on oled screens, which is a defect and not a norm for an OLED Displays.

Ah, well, I haven't owned any expensive phones so I can't really compare to anything other than the Moto Z2 Play, which also had a grainy OLED panel. If I were you I'd be annoyed as well, but I payed a fraction of MSRP for my phone so I can't complain.

I have noticed a weird behavior with the display. forcing it to 60Hz by enabling power saving mode significantly reduces the grain and make the panel a lot more uniform.
