Stuck pixel on camera sensor - One (M7) Q&A, Help & Troubleshooting

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

LCD quality question + pic of issue

I know its difficult to see on the picture but my replacement black One on the right is darker at full brightness than my white one on the left.. I know they use different lcd's due to quality issues now and the white one has a stuck pixel so at least the black one is free from that it just doesnt look right and is annoying me.. and input?

PS: when using the camera app the black one seems to always be focusing!! they are on the same settings, software and same looking at the same image, really strange
You are aware that you don't have the brightness turned fully up on the right device aren't you?

LOLOLOLOL that's an epic fail ... OP, surely you can see that in the pic! ... I have the black one and it only focuses when I touch to focus.
Yeah mines the same, works perfectly fine regarding that.
I have sorted the focus issue out with a hard reset they now both perform the same, the brightness is turned down slightly to show the blue colour better..

2 issues i have noticed so far. Display,Slow motion.

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.

the same here with yellowthint
i remember from op1 it was the glue they used
so maybe the same problem with mi8
or they use the same type of display like oneplus didt in op1

OLED Display black to grey smearing

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

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.

Question Faint White Lines with Grainy/Noise on Display

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.
