Okay, now that I got your attention, this is a SERIOUS issue. You may not even realise it, but if you’re not using MIUI, you pretty much have a Screen Burn In / Image Retention problem on your RN 8’s display. It’s temporary though, and goes away after a while. You can see for yourself, but I’ll come to that, and also to why it doesn’t really happen in MIUI. Also, the RN 8 isn’t the only device affected!
The issue:
This never happened over the 5 months I’ve used MIUI. It’s been a month since I flashed Pixel Experience Q, and I’ve noticed when opening Reddit, in its dark grey splash screen, I could see my notification bar and some app’s hamburger menu faintly. It started bothering me, and I started researching. How can I get burn in on a new device!? And heck, it’s an LCD. Turns out I’m not the only one. A quick Google search on “Redmi Note 8 Screen Burn In” gives you tons on people complaining, even here on XDA. Many think it’s a hardware issue, and replaced their display and still faced it!
See for yourself:
Open this dark grey picture linked below in full screen in your gallery. You may notice the notification bar burnt in. For a better example, exit your gallery with that picture open, set brightness to 100% and screen timeout to 2 mins, light mode, and just open settings and leave it alone. After almost 2 mins, quickly go back to your gallery with the picture open. You’ll see settings lightly imprinted into your screen!
Here’s the dark grey picture:

Solution:
Turns out that the Tianma LCD display panel found in most Xiaomi devices, like the RN 3, 4, 5, 7, 8, Mi 5 etc have to have a specific colour calibration. You need to set the Red, Green & Blue values to 90% in your ROM’s colour calibration. Take a look at these:

Here’s how colour calibration should look, I stole this image from somewhere

MIUI already has the right calibration by default.
But here comes the biggest problem for some of us. Pixel Experience Q, the most popular Custom ROM for RN 8, doesn’t have this option. I tried Franko Kernel Manager with the stock Kernel and Genom kernel, and the display RGB values make no effect. So as of now, I’m stuck with this. Any tips? ROM’s like Havoc should have it though. So dev’s, please set this as the default colour calibration value!
I hope this helped, I put 2 hours of effort into it haha.
On another note, I hope y’all are staying safe from this epidemic!
bro i have it in miui .. its hardware not soft .. i noticed it in different xiaomi devices like note 8 - note 7 - and sure poco f1 .. then noticed it in realme 5 pro .. not found in my very old samsung grand prime / though companies nowadays go to those low end panels .. all of them
I have the same issue on MIUI (stock rom) too.
I did the exact same steps you described and I got the burn in. Well it is not much, I could see it only on full brightness though. Not much of an issue for me on such a budget phone tbh.
Changing the color calibration for all colors to 90% might help to reduce this burn-in, speaking of custom roms to include this as a default setting.
But it won't help with this cheap panel, which is ineed a hardware issue anyway.
Setting all 3 colours to 90 % just reduces overall brightness nothing else.
Thank you! Display colors can be changed on crDroid 6.4
https://t.me/InceptionNote8/66967
this works well for me, use franco kernel manager
It is not the rom issue
I'm seeing this issue in stock rom and i never changed roms till now. It is bcoz of poor quality display panel. Get it replaced ASAP before warranty runs out
I dont know if this is universal but setting the colour tone to cool fixes the issue completely in my redmi note 8
just change the color calibration to this and voila, u never experience burn in screen anymore. i changed it couple weeks ago and no burn in AT ALLL untill this day!

I own a MI A1 it's 2 years, 9 months, 2 weeks, 3 days Old and has screen burns in.
not unlocked bootloader.
no twrp,custom roms,rooting.
but being a budget device (having eMMc type of storage) i have no regrets it performs very well against phones of Exynos 9609(UFS2.0), SDM665 (UFS2.1).
Comming to the topic "screen burns" will go away on its own not a matter of Great concern, leave it like that only it will automaticly go away its not Permanent .......... :fingers-crossed:

Hey!
I bought my galaxy 6 months ago. Not long after I noticed a minor issue with my AMOLED display. I could see blue "artefacts" in some bright areas of the screen from time to time. Nothing serious, just blue dots and stripes, subpixels. I even posted a picture of it on reddit (second attachment) more out of curiosity than anything but was later convinced it was probably a software issue. I did have some suspicions something might be wrong with my phone but it actually happened so rarely and the issue was so minor that I just got used to it because it didn't bother me that much.
I recently flashed dark core 2.2 along with rc6 and it got *significantly* worse. I could see blue subpixels all over the screen wherever there's bright white, generally on the lowest brightness setting. Now, I believed that the hardware got worse and it's time to ask for a replacement. So before doing so I obviously had to flash stock firmware and guess what - it all disappeared. So I flashed just the dark core again to go back to rc6 - and it was back again.
The thing is, I really love this ROM and I love the voodoo improvements that come with it. I don't think I can live without them any more. On the other hand, it might be difficult to convince people from samsung that there's actually something wrong with my phone - since it happens so rarely on stock ROM. And I think that this display defect is intensified by the screen improvements from voodoo/dark core.
My only idea is to somehow make it show up on stock ROM and send it to them just then. But is this even possible without rooting my phone? Does anyone has an idea why would these blue subpixels show up in white areas? Is it something they check with specialized equipment or do they boot the phone first to see what's wrong?
Anyway, guys if you could point me in the right direction or had any better ideas... Seriously, It would be helpful even if you said that I should just return my phone and hope for the best. I'm a student and I can't really afford to be charged for returning - what they think is - an operational phone
I attached two pictures
1. a picture of how my screen behaves after flashing the latest dark kernel
2. a picture of how my screen sometimes behave on stock kernels
I'd appreciate any help or advice
Hi guys,
So somehow, (and I really have no idea how I even managed to do this) I went three months without noticing the horrendous black clipping on my Int. Note. Last night I was cursing YouTube's streaming and then realised something was up. After a quick look at the test PNG which I quickly discovered I'm unable to see 1, 2 and 3 which makes for a pretty ugly experience when watching darker videos.
So my question is this. Should I root and go ParanoidAndroid to try and alleviate my issue (I assume part of this process will include flashing a new kernel which is where the issue lies?) or is there a chance that Samsung will ship a new kernel with the imminent (we hope) JB update?
I'm no newbie to rooting and totally hacked my HTC Desire to within an inch of it's life (figuratively speaking, I never bricked it) and I'm always tinkering with an Advent Vega for fun. However, I'm a bit worn out by rooting and reading up on all the proper routes, new radios, kernel issues, bugs etc. I'd like a 'quiet' life with the Note where possible!
Do you think I'll 'get away' with rooting this time or is it going to be likely needed to fix this problem?

My opinion:
Samsung correcting the Gamma table on the firmware, so dark colors appear really dark and not light gray or completly black is unlikely. They are following the strategy embraced by other manufacturers and just release a new model with a slightly better CPU and fixes for the bugs of the previous model.
xda-developers community releasing a ROM that is realy usable and fixes this: not likely either. A ROM that has no support for camera, HD recording, FM radio or S-Pen is not going to convince many people to switch.
I recently took my Note to Samsung technical service because the screen looked yellow (another known manufacturing defect), and they replaced the entire screen, but the new one shows the same black clipping problem.
Apps like filter your screen just lower the contrast so the blacks become more gray, but the darkest tone of gray the Note can show is still too bright, leading to anything below RGB (50,50,50) appearing almost the same tone of gray.
I have just moved to a phone by other company and compared it to the Galaxy Note:
Screen is IPS, viewing angle is not so ample as in an AMOLED but at least white appears white, not light brown
The gammatest.png image is displayed correctly, top row of squares going from black to very dark gray.
Brightness on the Note is limited to avoid burning the AMOLED too fast, and even so, I had burn-in on the top of the screen after only 3 months
My new phone has 1 GB RAM, and 980 MB are listed, not 808, and I have 400 used normally, with 580 free. Note had usually 700 MB used
My new phone seems to spend more time on deep sleep, no Samsung apps or services working on the background
Hi quys!
first of all ,sorry for my bad english!
but, i recently bought xiaomi mi 9 , i had lot of problem with it till now but the most important of it, its about display panel.
my perivious phone was samsung s8 Plus and s8 display was awesome (its 2 years before phone) but my mi 9 display not good as s8 plus , not even close, is this normal? or my phone have problem software?
Hi, what problem did you get ?
I had the reglular Samsung S8 and I find the Mi9 panel not far from the S8. As it is 1080 and not 1440 it has not as high pixel density, but I am more than happy with the Mi9. Never have any problems in bright sunlight as I could have with the S8.

thanks for your reply, but i a disappointed the first time i saw mi 9 display. i think the icons are like washed out and not sharp. i saw someone in this forum said after update mi9 , have a better display and compared his phone with S9!
my next problem is updating miui. my mi 9 is china pack and the website that i bought my phone , open phone box and flash global rom on china rom in china country and send them to customers. i have weird problem with the phone.crash app frequently ,google play service crash and stop ...,the worst problem is closing all apps and go to lock screen and after unlocking phone ,the message "find device closed unexpectedly" showed me and if im not reboot my phone this problem repeat and even sometimes my phone reboot itself even twice or more. now i signed out from my mi account and i turned off sync option and set off battery optimization and lots of setting option, and betternet app (vpn) not use anymore (this app made a lot of problem for me , i think) and now i have a better experience. i wished a new update fix my all problem . i am on V10.2.9.0.PFAMIXM Global Rom and new OTA Update V10.2.13.0 shown on my phone after downloading update , my phone reboot to start the update but after 25% in fastboot update failed and not update this time OTA Update is 2.2GB . i repeat this process a lot and no progress. even downloading zip file by PC and update manually not help, phone it said this is not official update.
what is the problem of my phone for OTA Update!?
You might be looking for more vivid colors. Go to Settings, Display, Contrast & Colors, and see if moving between "increased contrast" and "Standard" gives you more of what you expect to see. You can also set the color temperature to better match what Samsung uses by default

Yes, didn't think of that as I always tune down the overly saturated Samsung displays!
The auto brightness also seems to be a bit off. I have my brightness forced.
If you have DC dimming turned on, it can also change colors if you are on a lower brightness.
Coming from note 8 i am very satisfied with the screen, if the note is a 10" the mi 9 is 9,5". (i change the settings to be more vivid). I

Recieved my K20 Pro yesterday and I've noticed that there's a slight green tint on the upper left corner.
Here's an example.
imgur .com/a/Tr9b61H
It kinda goes away on 80%+ brightness and also appears on white and that gradient, sadly I can't take a photo on a white setting because it doesn't appear on the photo.
Any people out there that has a Mi 9T, K20, K20 Pro that is experiencing the same problems?
We can also share problems that we experience here so we could test it on our devices, feel free to share! Thanks!
Additional questions:
1. Also is there any way to know if the device has been used, returned or a refurbished one?
2. Idle temps is 35c, when gaming it reaches out to 50c~55c. Is it normal/okay?
3. The thing is if I refund or return I'll be getting the same device, so do you think it is worth the hassle?
Sorry I'm a new account so I could not post links. Thanks!
I'm on the latest MIUI version, no other changes made.

I bought the Mi 9t pro on the 28th august and it had some issues so i returned it and bought a new one. Arrives today, we will see, i would reply if the problems repeat
the problems were:
1: With the dark mode activated, The contrast with true blacks and gray, while moving the screen, the pixels that had to turn from black to gray had a Blue/purple tint. most noticable with Less than 50% brigthness
2: with, again, gray tones ,the screen had a line in the middle across the display that had a gradient towards white, like in spotify, for example, wasn't a solid color.
3: Some touch issues, most noticable while gaming(Call of duty mobile in my case)
Similiar issue. @oliese have you returned it, or its normal scenario with led panels?

Hi, I recently bought a Realme GT 2 8/128GB Global RMX3311_11_A.14 firm and have been using it for past couple of days.
What I have noticed like artifacts around black text on white background, like a bright halo under dark shapes and clear/light background, it's like a 1px brighter-than-the-background, like a broken anti-aliasing/ClearType or maybe is that the sharpness is very high.
I have tried all the configuration options available for the screen but there have been no changes. For example, in the list of Wi-Fi networks, in the password field, if you look at the black line, it is in one of the places where it is most noticeable.
https://imgur.com/t50LOm5
it is very difficult to capture with a camera, this is not my phone but the same thing happens
https://imgur.com/zOkyWWG
I think i have same problem which is reported in this other thread for a Xiaomi phone https://forum.xda-developers.com/t/over-sharpened-mi-11x-amoled-display.4319715/
Is this normal or there's any problem with my display? Is this a Realme UI 3 issue and can be solved in following updates?
I have other three Amoled phones and this DOES NOT happen to any of them! (Realme 8, Oneplus 3T, Xiaomi Mi A3)
thanks!

Do you have DC Dimming enabled ?
I noticed that when it is enabled in low brightness and black background there's some flickering on the page text when scrolling.
But that particular issue I don't have.
Hi apsol, thanks for your answer
No, I did not have DC dimming active, I have tried to activate it but it has no effect on what I comment
with time I'll get used to it, now I know it's there and I see it. What I would like to know is if it is a problem with this AMOLED panel or rom/driver issue which could be adjusted via software
I know how it is, once you see it you can't unseen, it would drive me nuts too. Hehe
Have you tried testing for dead/stuck pixels if it doesn't show there my guess is software.
I'm on RMX3311_11_A.14.
What about you ?
Hi,
Same firmware version here, RMX3311_11_A.14 global
the truth is that I am not sure if it also happened with the A.13 because I almost updated it at the moment, I did not realize this until I was in the A.14 ...
thanks
The same problem on my phone. It is easier to see also on black background with white font.
Unfortunately I think this is a screen issue not soft
Have anyone have similar issue? Is this global problem or only 2 of us struggle with this issue?
Check if you have high contrast text enabled.
I have high contrast disable ( but the same issue is visible when option is on). Do you have this is issue? Or should I send my phone on RMA?
I don't.
If it bothers you that much return it.
Hi again,
After continuing to search for information on this issue, I found following post on reddit that I think has the same problem with an iPhone 13
https://www.reddit.com/r/iphonehelp/comments/tdy5tc
I think it's a common problem with AMOLED screens, but in some it is more noticeable than in others and it also depends on the user
after detecting it on my Realme GT 2, if I make an effort, perhaps I could say that it also happens on my OnePlus 3T, however the difference with my Realme is remarkable, the same with a Realme 8 of a family member
By the way, another thing that I have detected is a color shifting when the viewing angle is varied, much higher than in my other devices with AMOLED, it must be said that the larger the screen, the more noticeable it is
I'm a little disappointed with the screen to be honest
thanks

I came specifically to this forum to check whether its true about the screen's colour shift and font edge issues. Seems its true. Its believed that they have used the same samsung E4 hard screen, that they used in oneplus 9RT. You can check 9RT's display review below:
https://www.gizmochina.com/2021/10/22/oneplus-9rt-review-perfect-balance-camera-price/
There is also a Chinese video on GT2 display. Its a review of k50 and gt neo3, but they have shown display of gt2 also. Watch from 2:30 min.
I don't see that problem on my gt2 in normal use.
I also have the blue shifting even when looking straight. I try to ignore it.
Someone told me it was the screen protector but I never removed it to be sure.
But every review I've seen there is color shifting.
