Stuck pixels on display - Mate 8 Q&A, Help & Troubleshooting

I have a week old L29 Mate 8 which was imported from Asia. Returning the phone for warranty would be a big problem.
Recently I noticed with a dark background that the display has four stuck pixels in different spots around the screen. They appear to be white or blue.
Now that I know they are there, it bothers me because I am quite obsessive about these kinds of details and this is the most expensive phone that I have ever bought.
Is this quite a common experience with the Huawei Mate 8?
Does anyone have experience with a solution that has proven to be quite reliable / successful in fixing stuck pixels?

Try running this page for 10 minutes each pixel:

It usually fixes stuck pixels on PC monitors, you might try your luck with your Mate 8.

Are your Note Pro's yellows green? Is mine defective?

Hi all,
I've been an original Note 10.1 user for 18 months an upgrade to a Note Pro on a great deal. It arrived this morning and at first everything was wonderful, but the moment I fired up Sketchbook Pro, the yellows looked dull and greenish. A large stroke of pure yellow painted some seemingly olive green colour. It's not really suitable for art. Video and photo's tend to look okay though (possibly even better colour balanced that other devices I have), so it's hard to pin down. It also happens in other applications - the colour picker in SNote has a really sad, depressed yellow. I've taken a few photos alongside other displays but depressingly they capture a pure yellow which is very odd.
Googling around, the Lenovo Yoga 2 uses the same screen and has users grumbling about the yellows, and a BIOS update has improved things but not fixed them, suggesting the RGBW Pentile display is just incapable of accurately displaying true yellows. If that's the case though, why wasn't this brought up in the many glowing reviews of the Note Pro?
The best way to ascertain whether mine's a defective/improperly calibrated unit or not seems to be to ask other owners, hence my enrolling here. If you paint some pure yellow in Sketchbook Pro, does it look yellow? Does it pop like a ripe lemon or banana, or look somewhat sickly and off? Is the Note Pro just incapable of rendering such colours?
As an aside, why aren't colour calibration options included on devices like they are on TVs?? Seems an easy way to allow users to tailor their colour preferences. Edit: Huh. Samsung does provide Screen Modes for their tablets, just not those from Hong Kong!
Turns out the Hong Kong model doesn't have Screen Mode settings according to the manual. US and EU does, but not Hong Kong. Why?! So I'm guessing that this model is limited to 'movie mode' colours or something. If you vote above, please mention which region your Note Pro is from (and better yet, if changing the Screen Mode changes the colour rendering).
Have you found out anything else? I've the same problem (I've already voted).
I'm questioning myself if I should send it for RMA or not, since I live in Argentina.
Hey guys. I noticed that whenever I pull down my notification / settings bar the yellows displayed on background stuff looks normal. This is kind of an annoying find, as it shows that the note pro is capable of correct colors

Screen issue? (uneven brightness/darkness)

My OP6 have this uneven lighting on my screen. It is visible when you have a dark grey background, in a dark room, and the brightness is on 5%-10%. It's also visible when you open up chrome app and close all the tabs until you got nothing but a dark background and a + for new tabs. Is this normal? Or should I RMA it?

Here you go
I don't think that's normal at all. At least my OP6 doesn't have that. The brightness is even across the entire screen.
Normally the issue only have Huawei and the LG OLED Panels.
OnePlus 6 have an SAMSUNG Super AMOLED Display, and there is no issue with uneveness Display in low brightness.
Can anyone else confirm this if it's normal or not? Please try again and use this image i attached. The uneveness is quite visible with it.
Go in a dark room.
Full screen it (make sure there's no other bright elements are showing).
And lastly, set your brightness to about 10%.
Please tell me it's normal :/
*edit. Funny, can't seem to upload the pic.
Welp.

@aserate: I have the same issue. I tested it yesterday and saw some lines and uneveness.
Im happy, that I bought the OP6 from Amazon. Now I give the OP back and buy the Mi Mix 2S without AMOLED.
Only Samsung build AMOLED Display without uneveness and lines. I tested the screen from Mate 10 Pro, P20 Pro, Google Pixel 2 XL, LG V30, OP 5T,...
All of these smartphones had a problem with the OLED / AMOLED Displays.
Im wondering, that the user, who test the phone for YouTube or a mobile site, dont see the bad screen.
I bought the Mate 10 Pro 3 times ans the P20 Pro 2 times from different stores. All the devices had a bad screen.
I hate the UI from Samsung, that is why I only buy now smartphones without AMOLED, only IPS or Super LCD.
I don't have this issue. I checked 5 different OP6 units and all were ok. Only one had some slight uneven brightness, but not as visible as on your picture.
Appreciate your feedback. I guess i have to rma this since it's clearly an issue. Praying the replacement won't have this. Sad to know after watching linus' op factory tour with all that quality checking and stuff, common issue such as this still exist. Welp.
There is a way to completely deactivate the top part of the display to completely hide notch. But I don't want clock on the left of the notch I want it on both. There is a way?

Rubbish? I´d tested all of the phones:
- S8 & S8+
- S9 & S9+
-Note 8
All of them don´t had any display issues.
I´d tested:
- Mate 10 Pro
- P20 Pro
All of them had uneveness and lines on the OLED Display
I´d tested now:
- OnePlus 6
THis phone has uneveness, too.
Now I have OnePlus 5T and this phone has a perfect OLED display.
If I have the chance, to get a samsung phone with OnePlus Oxygen OS, I would like to swap asap!

i rest my case as you said all are perfect this proves other wise
Got the same issue. Also on my fourth device already because of loose alert sliders. my fourth device has a loose alert slider and an uneven screen. right side is darker than the left side and its noticable in dark menus, notification shade etc on low brightness
No problems for me here in terms of uniformity.
Great panel, but I wish the calibration was better:
- calibration too cold
- oversaturated
- gamma way too high
- black crush
I had this problem in 2 Oneplus 6. I made a RMA and got a new unit, without the banding, but a defective corners (a white glow in dark images). So I got another one, finally a perfect unit.
The other one was purchased via amazon, with the same banding issue, so I got an exchange.
All of them were red Oneplus 6.
The OP customer service was very helpfull resolving the problem. I give a 10 to them.
Anyone can check the screen with this images or an app called oled tools. You need a dark enviroment and low brightness
Im kind of hestitant to replace since im on my fourth device already and dont feel like waiting anymore. Thinking about returning and waiting for the 6t. Id have to use my galaxy s5 for a few extra months though...
I just received my replacement unit 2 days ago, I was waiting for it for almost a MONTH. Unfortunately, I still have the screen issue. I can't believe I was waiting for nothing. While waiting for the replacement, I only used a f***ing keypad phone, and it was really hard for me. Have I known this issue is fairly common, I haven't RMA'd my unit just to have a big chance to have the same issue again.

Ghosting

I've just got this device but am in two minds whether to open it. After it arrived I read that it has issues with ghosting, that the frame rate on the screen is poor. Is this true?
I have no issues with those things.
It's the best Android phone I ever had.

^^ ditto
No issues here...
No problems here... V10 is a great device
No issues with ghosting - but if you want to run a custom rom you should send it back and get one from a different company since you can't unlock the bootloader on Huawei/Honor any more.
I have this issue when the temperature is low. It was happening on my honor 8 too. I thought it was a common property on the lcd screens...
Thanks for the feedback. I went with the Honor View 10 and it's brilliant. The best phone I've had in the last two years was the Mate 9 but it crashed on an update and ended up in the bin.
I had the S9+ for a few months but the curved screen bugged me. Then I bought a note 9 and sent it back. I feel this is a brilliant purchase, great mid range phone. Only annoying thing is when I switch off and accidentally screen shot and the video stabilisation. I can live with that though.
It's Super fast, snappy, brilliant stills camera and fantastic battery life and no ghosting. Love the screen and no anxiety over breaking like I had with the S9+ with a curved screen. Very happy with this purchase and a third of the price of an S9+.

Mi Note 10 Pro / CC9 Pro Premium AMOLED Burn-in

Got it 2 days ago, barely even used it, still waiting for unlocking permissions...
I believe it's just Temporary Burn at max brightness but I've never seen it be so obvious on literally ANY display before!!
The shadow you're seeing is caused by the Brightness Slider in dark mode, and can be recreated in less than 5 seconds, and goes away after 20 seconds
I read somewhere in the MIUI forums that it could be a software problem regarding MIUI 10/11's advanced display algorithms, but I highly doubt it as I know the system only changes the overall contrast based on lighting
I did multiple tests with dimming On/Off, and compared it to my Mi8 SE running some Xiaomi.eu MIUI 11 beta, it's a completely new problem on the Note 10
Please test it yourselves as well, I'm looking forward to detailed replies
Many thanks!!
I have mine by 2 months, mi note 10 with cc9 pro xiaomi eu rom, started noticing the same things latest 2 weeks ( you see it better in a dark enviroment ).
Max i reach is half brightness, can't stand more, so i can guarantee that is not because of max brightness as i've seen that happening even with just like barely readable brightness.
Reading mode and anti flicker don't help.
I can even assume that with anti flicker on ( that i always have ) is worse.

UPDATE:
The problem has gotten much worse, does anyone know who's manufacturing these for Xiaomi / Huawei?

The problem has gotten much worse, even the white text I'm typing right now in the XDA Labs app is leaving light shadows when I backspace, I'm %99 sure that I have a factory deflect, and no warranty, so I actually might end up replacing the screen in a few months if officially stated fixed versions become available

Visionox manufacfure the display, not the usual Samsung xiaomi used for their oled. Samsung is prone to burn in too, every oled is, but it is clear that quality talking this display is inferior to the Samsung one's, never seen this kind of ghost burn in until this phone. Let's hope will always remain only a temporary burn one
This is unbelievable... even the Samsung Galaxy S5 mini has far superior image quality and calibration
I don't have any burn-in problems yet but I can agree with you about the calibration and quality issue. Even when I change it to warm or cold, I can't notice a big difference, and I don't really like the colors it shows. Most of the reviews say this phone has a great screen, I don't think they were lying but there must be a problem with the quality standards of the brand of the screen. My 3 years old S8 Plus shows better colors with its cracked screen, which is annoying.

Question [CLOSED] Redmi Note 11 Pro Plus AMOLED Display Problem

Hello,
I've been using Redmi Note 11 Pro plus for the past few days. I had been using a Samsung m30s before and compared to that the display experience in Redmi Note 11 Pro has been dull.
Last day I noticed something. I had tried using a completely black wallpaper and then I noticed how the black was not proper. Colour was leaching out through sides of display like a backlight bleed.
I had seen previous reports of a possible Redmi Note 11 Pro Display problem which made me do a display test on the phone. Then I noticed that this bleed like effect was present also for white as well as dark grey colors.
However these went away after I restarted my phone. So I wanted to know whether anyone else experienced this Redmi Note 11 Pro problem.
<Moderator Edit>: Self-promoting video link deleted.
This is a software issue that only occurs on MIUI. On custom roms this problem doesn't show up and the screen is completely black.
Probably a software issue, mine is noticeable when swiping the brightness while on the black screen test raging from 8 - 15% of brightness where I can see the bleeding
Hello I was planning on getting this phone (Redmi note 11 pro 5g) but after researching a bit I came across this thread. I heard this is an issue that affects both models. Is this an issue that affects only certain units or do most have amoled problems? Does this only show in 120hz mode? Thanks!

My device has no such problem. I generated a #00000000 image using an app and tried viewing it at max brightness in a dark room and the screen legit turns off. Its kinda freaky to see a display turn off when you know its on and expect some bleed. I come from lcd so thats what I expected. Needless to say I'm glad my model wasn't defective.

I have compared the Redmi Note 11 Pro Plus 5g (peux) with last years top model Redmi Note 10 Pro Max and this display seems to be more colorful and vibrant compared to last years model. That one seemed more washed out in the same display modes.

The issue is not present at 100% brightness. Try keeping the image, and play around with the brightness settings from 0 to 100. Then, you can notice that at certain percentages, the backlight bleeds quite heavily. In my device, it's at around 30-50. Some other users report that it's happening to them at 40-60.

Tried it and still fine.
I have the same problem with a redmi note 10 pro, with brightness between 0 an 19%
At 20% and more, the black si.. black

hi does this affect daily usage? I tend to use my phone a lot at night in bed so it would suck if the bleeding is that bad. How noticeable is it when watching content with dark scenes/backgrounds?

On my day to day usage, I find that it's not noticeable at all. However, If you're watching content that has pure black elements, it is very noticeable. It's inconvenient, but usually when it happens I just turn down the brightness a little bit and it's gone.
I wouldn't say it's a deal breaker, I still think the phone is a pretty good value, but buyers beware. There's some hope that it'll be fixed in an update at some point but I wouldn't hold my breath. Just be aware that your mileage may vary.
Is this an issue that is present on 60 or 120hz? Saw a couple of posts on other threads that say issue disappears on 60hz. Is it the same on yours?

The problem still persists regardless of whether or not I set 60 or 120hz. On my device, at least.
Guys, try this app called Oreo colorizer. This solves the issue.
It forces the display to shift its color space to DCI-P3 instead of the default sRGB according to the below XDA thread.
So the issue is software related. NOT HARDWARE. Hope Xiaomi solves this by updates in future.
[APP][Official][v1.1] Oreo Colorizer
Oreo Colorizer uses an invisible system overlay operating in wide color gamut that forces the display to shift its color space to DCI-P3 instead of the default sRGB. Optimized Rendering only affects apps that use SurfaceFlinger (IE: 99% of all...
