Issue:
1.Some users (like me) must have faced issue of screen ghosting or retention in which if the device is used at max brightness, they see a ghosted image on sides of their phone. (Especially visible when switching from a light theme to dark, for eg, going in chrome incognito mode you will see it)
2.Usually it happens after flashing a custom ROM or kernel.
Fix:
Method 1:
1. In case if its a custom ROM, go to Settings > Display > LiveDisplay
2. Set the Color Profile to ‘Standard'.
3. Go to color calibration setting and set the following values:
Red at 90%
Green at 90%
Blue at 90%.
4. Keep the display screen of for some time (15 min) and boom! Issue solved.
[Note: Max brightness may feel a little less than before but its still better, you will get used to it]
Method 2:
1.In case you have a custom kernel, you can refer to other threads or manually set the values of Red, Green and Blue by yourself by using a ‘Kernel Manager App'.
Just keep it at minimum than its original values.
Conclusion:
This issue is NOT a hardware issue, its a software issue that can be fixed by implementation of any following methods.

I got through some other threads of Redmi having same issue. Just the difference is in the settings I used, you can customize it as per your own will BUT make sure that the ghosting does not appear by use of that setting. If successful, you may replay
What are you talking about??
This issue is not available in Pixel exp plus pie, is this a Stock rom issue??
but i didn't experience it for whatever hours i was on stock Miui.
It is not software issue, but the low hardware quality I presume

It is not the case that every user will face it. In case if it occurs, you may make use of these procedures.
Mostly, if you use max brightness and switch suddenly to dark grey, you can notice it (in custom ROMs / custom kernel ).

No it is a software issue. I am not talking about the yellow spot issue (that is hardware issue)
This one is ghosting or temporary burn in caused due to change in the default color calibration.
I faced it before but after trying the above settings, even at max brightness, the ghosting did not appear again. So it actually works.
Ghosting does not remain forever in LCD. So its not harmful to hardware in any way. (Just buggy)

I agree. Screen Retention or Ghosting is mostly present on other devices (I'm not talking about the Pocophone alone but on every other devices) and can be fixed via software implementations or updates. Changing color profile and/or color settings can be a solution too.

Well it appears on every side of the screen and not just bottom. Even when I boot to twrp after being on a bright screen for long time, the status bar, some text and navigation bar appears. ... It fades away tho, not permanent as in amoled. LoL

I am neither using a custom ROM nor have done anything in past which can have these after effects. I am facing these issue or may be noticeable after the rollout of the MIUI11 ROM. So i contacted other who owns pocof1 , but their device don't have these issues. Then i contacted the service center and they reinstalled the MIUI11 but the problem persists.
So then i thinking of a screen replacement since i m on a warranty period so should i do that to solve this issue?.
Also u gave the settings to resolve the issue for a stock/CustomUI but wht for the MIUI , pls give the setting for them too.
pls answer all my queries!

This reply is pretty late, sorry for that.
1.You need to be rooted.
2.Download ColorChanger app from PlayStore.
3.Give root privileges.
4.Decrease the color in Custom1/Custom2/Custom3 by long tapping to these values:
R:240
G:240
B:240
S:1.00.
5.Save it (top left corner)
Con: You need to apply this every time you boot into your device.
You can upgrade to pro and enable “Activate on boot" from app setting to make this happen automatically.
I did it but it doesn't work, I'll consider change the hole panel
Can you take a look at the attached screenshot and confirm if these values are okay. Apart from RGB values, do I need to tweak anything else? Thanks in advance.
Oh I see, I got this problem, and realize I set livedisplay profile to dynamic. I thought my screen was wore out

This is a hardware problem, i tried everything and failed so i got original lcd folder replaced from the service center and now no screen retention.
I am from India itself, do you know which service center to go to? Since poco split from mi, am i in trouble or i should head to the mi service center. And my is under a warranty of 6 months and i'm in the 3rd month now....is it free or you got to pay money for the service?
Thanks in Advance.

I solve this problem on miui oficial without root, Just applying standard contrast on screen settings.

Over the couple of months, many Moto G4 Plus owners have been complaining about the screen burn issue.
Well there wasn't a fix for this through software except Blue Light Filter (which didn't work for me), and while trying for the fix, I feel I have found one.
Prerequisites:
1. Android Nougat (7.0) (I am running on the stock NPJ25.93-14 i.e the 1st December 2016 Security Patch)
2. System UI Tuner enabled.
No Root Needed.
My device is the Indian variant XT1643 i.e 2GB RAM variant.
For those who are on Android Marshmallow CM based Custom ROM, you can try using the live display and setting the value nearby 3000~3500K (Although I am not sure if this would work since I haven't tried it yet).
Its the Night Mode!
1. Go download the "Night Mode Enabler" app from the Play Store --> https://play.google.com/store/apps/details?id=org.michaelevans.nightmodeenabler&hl=en
2. Open it and click on "Enable Night Mode".
3. It will take you to System UI Tuner where you can toggle night mode on/off.
4. Go to the quick settings edit option, and you will see a new tile - "Night Mode".
Toggle on the night mode and see the effect after some time (it started to show effect as soon as I enabled it and fixed the issue within 20 minutes for me).
[Q]. What will happen if I toggle off night mode?
[A]. The Screen burn will occur once again.
You need to have the Night Mode to be always on in order to get rid of that Screen Burn issue.
I know that many might not like the color temperature of Night Mode, so if you have a CM based ROM, you can edit the temperature with "Live Display" option.
Well, try it out and lets see if it works or not!

First of all, thank you for sharing this.
But your "fix" is just a workaround and not a proper fix for our broken displays.
The only real fix is to replace the display.

Umm, I guess you are right. I have changed the title now.
Even screen replacement is not a permanent solution. I have replaced display and within 3 weeks issue reoccurred
It fixed the issue
The night mode enabler has fixed the issue for now. But the screen is of some weird color(especially white background).
Anyways, Its good to see my phone screen without the screen burn issue after such a long time.
Thanks
RGB calibration is the best fix for screen burn in !
unfortunately if u r on stock rom ,Then you have to root ur device .

Kernel Adiutor can modify rgb values for example.
Hi, finally I have time to make a thread about this. The problem is present on every non stock ROM, no matter if it is lollipop, MM or Nougat based. At low brightness, it seems like the screen is uppering-lowering brightness really fast. I have made a video, because "maybe" I didn't explain it very well :silly:
https://drive.google.com/open?id=0B1r3IiDMSm40R3Y0NlhzQXowOGs
(the phone is placed in the dock but it is NOT charging, in case you wonder. Also there is a small line of pixels that look like "interferences", at the right of the screen, near navigation bar, but this only happened with a kernel provided by optimumpro in order to try fixing the flickering issue)
Here and here I attached logs with different ROMs. (these ones have already been reviewed in other previous posts, but maybe they are still useful)
Nailyk asked me if the problem is present in recovery too, but I can't tell you, since the screen background in recovery is black and the flickering is more easily noticeable in white backgrounds. Anyway, I'd say that there is no flickering in recovery but I'm not sure. I may need a white themed recovery with a vey low minimum brightness value.
Also, it seems like I'm the only one with this problem (AFAIK) so there's always the chance that it is a hardware issue with my phone, but it would be strange cause with stock ROMs the screen is perfect, and screen brightness can go very low without problems.
So I am here to ask for help, and to help helping anyone interested in fixing the issue. Thank you very much!
@nailyk @optimumpro @Myself5
i too face this issue... i think this issue is GPU related... i also have flickering on stock roms. but of i keep my device warm enough.. the flickering goes away...
Interesting. I will test it again in a warm environment. But I think that this starts to sound more like a hardware issue...

Glad you opened the thread.
About recovery it will be interesting to know if it is only kernel or rom+kernel issue.
Also flashing a recovery is faster than a full rom for testing purpose.

I've installed a white theme in twrp and I didn't notice any flickering.
News: the bug is also present in Concept rom. I've checked twice and it is. But I forgot to take any log, so if you need them just tell me.
Also, I've checked very carefully if there's any slight flickering on stock Sony rom (actually I'm on ExistenZ with EliteKernel) and there isn't. I even lowered brightness to the minimum via kernel settings, as EliteKernel allows you to tweak colors, and I still don't see any flickering.

Interesting.
Right now I don't have lot of time. As this flickering doesn't produce into recovery it shouldn't be kernel related.
Here are some experiments you can do: Set a high value to screen timeout then on root:
Code:
[email protected]:/ # find /sys -iname "*bright*"
/sys/devices/leds-qpnp-23/leds/rgb/brightness

/sys/devices/msm_sdcc.2/leds/mmc2::/brightness
/sys/devices/msm_sdcc.2/leds/mmc2::/max_brightness
The two interesting values are lcd-backlight/max_brightness & lcd-backlight/brightness. Your path will differ, depending on the kernel used, panel, etc...
Code:
[email protected]:/ # cat /sys/devices/mdp.0/qcom,mdss_fb_primary.168/leds/lcd-backlight/max_brightness
255
Here is my max value with a specific rom. Then I can set any value 1<x<255:
Code:
[email protected]:/ # echo 20 > /sys/devices/mdp.0/qcom,mdss_fb_primary.168/leds/lcd-backlight/brightness
and see the back-light changing.
Please make some experiments with this and collect data. Like working rom name, backlight_max_value, flickering start at 10, kernel version, and path of /brigthness.
If it is related to this value you should be able to reproduce into recovery.
P.S.: I just test on the CM-12.1 and notice something weird:
Code:
[email protected]:/ # cat /sys/devices/mdp.0/qcom,mdss_fb_primary.168/leds/lcd-backlight/max_brightness
4095
[email protected]:/ # cat /sys/devices/01-qcom,leds-d800/leds/wled:backlight/max_brightness
255
and only /sys/devices/01-qcom,leds-d800/leds/wled:backlight/brightness is affecting backlight.
Noticed flickering for 1 to 4 on my device.

Use a find command like:
Code:
find /sys -iname "*bright*"
Anyway I noticed a problem on the cm-12.1 related to this. Didn't find the exact bug right now. My workaround was: trigger max value (with the slide) then go back to the wanted value. Flickering disappear. Need to reproduce to fix.
i have the flickring and ghosting when my z3 is cold and the problem gone when it heats a bit
could this problem be from my rom (6.0.1 ExistenZ)!

i think its hardware issue
If it happens on stock rom it sounds like hardware related, but as for me it doesn't happen in stock roms, maybe it's a mix of hardware - software.
Could you take a dmesg (better if you do it just after booting) to see which model is your panel? If you don't know about adb, you can do it with this app https://play.google.com/store/apps/details?id=com.eolwral.osmonitor Go to settings, check root permissions, then go to messages -dmesg and export. @TechnoFreak750

And the screen brightness is changed (at least) by the lines marked in bold. I haven't try the others as I don't know if they are screen related, notificacion LED or whatever.
Edited: One more thing. The minimum brightness in stock ROM is 29. If manually set to a low value, let's say 4, editing the file, the flickering appears on stock ROMs. Now I'm going to try Jaguar ROM again to see if "29" is as dark as stock (I will have to trust my eyes and memory), and if there's flickering with these value. Because I always felt that stock ROMs were at least as dark as AOSP when using minimum brightness in settings.
Edited 2: On Jaguar, with /sys/devices/leds-qpnp-24/leds/wled:backlight/brightness = 29 there's no flickering. It seems brighter than in stock but probably it's my perception, as I can't compare at the same time.
I think we can assume that it's somehow hardware related, but I don't know if there is any software solution or improvement, since the software and the "routes" are different in stock and AOSP.

Great report.
Setting a 29 value will not provide the same result if max_brightness is 4095 or 255
Suppose 29 was set with max_brightness 4095 it will have a corresponding value of 2 for max_brightness 255. (cross multiplication: (255*29)/4095=1.2)
I remember reading in another thread that you are using cm-12.1 right now. Is it right?
P.S.: you can play with /sys/devices/leds-qpnp-ec948600/leds/led:rgb_*/brightness , it will bright up the notification led

If it happens on stock rom it sounds like hardware related, but as for me it doesn't happen in stock roms, maybe it's a mix of hardware - software.
Could you take a dmesg (better if you do it just after booting) to see which model is your panel? If you don't know about adb, you can do it with this app https://play.google.com/store/apps/details?id=com.eolwral.osmonitor Go to settings, check root permissions, then go to messages -dmesg and export. @TechnoFreak750

Can you tell us more details please? (step to reproduce)
Also do you have an original panel? If it is a replaced one read the thread to reproduce tests and giving us the panel name.

I have a bug that I can't fix on my redmi note 6 pro.
Pixels remain dead for long periods of time. For example, if I am reading a pdf and return to the home screen, transparent parts of the pdf still appear on the screen, usually at the top. These overlays change frequently, and there may occasionally be none. The darker the screen that I have open the less I notice them.
-I detected the error right after changing some settings in nova launcher, so I tried changing settings, resetting the app, trying other launchers, but the problem persists.
-Of course I tried to restart the device several times.
-If I take screenshot the overlays do not appear.
I have the Havoc ROM. I don't know if it's a problem with the ROM, the launcher or something else. Can anybody help me?

What you are experiencing is normal for Redmi phones with Tianma displays (its called screen burn-in). Even I have that problem. Well there is a fix. If your kernel supports configuring RGB like mine or say your ROM has option for RGB controls. What you can do is set RGB to 95, 95, 95 from live display option in settings.

Oh cool! If I helped you don't forget to hit that thanks button ?
I don't know if this is a "bug or feature" type of situation, but I just got my brand new Poco F2 Pro and I noticed that the colors in the lock screen are washed out. I deleted all the registered fingerprints from the Settings and suddenly the colors are... colorful again.
So, is this a bug that Xiaomi can fix with a software update, is it a hardware issue, or is it intentional and necessary for the fingerprint sensor to work?
Any info would be greatly appreciated.
Thank you
i can confirm this phenomena
Correct observation.
Don't know the reason but probably a bug not solved with Miui 12.
It did this on MIUI 11 as well just not as noticeable. It drives me insane tbh, especially the quick settings menu. Can't even take a pic of it. I've tried a handful of lockscreen themes and found one that is bearable as it let's you tint the lockscreen.
I see it too
Same here.
Did you use advance color gamut setting instead of auto? I noticed this when color gamut option is not set to auto.
Make sure if you're using dark mode, in settings/display/dark mode you don't have wallpaper darken... This creates a washes out look
I have experienced this too and have found no surefire workaround. However, what does seem to be more effective is if you set your wallpaper through the options in the settings menu and not through a launcher (like Nova for instance). It reduces the grainy quality of the lockscreen, but the image is still not the best.
I dont think its a bug, since in-display fingerprint reader needs a very bright light-source, the display itself will illuminate to the max for the fingerprint scanner to works, which is essentially the same as "sun-mode". In that mode, all color will look bad.
Same I felt it today...I faced then I went to shop they wiped out my data :3 when I setup my wallpaper and the fingerprint it's happening like before..and there's another bug on dark mode as well ,when you lower your brightness completely,the settings font will start its color fading :crying:

Auto mode actually gives a better contrast to the lock screen wallpaper than Advanced, I didn't realize. ?

Unfortunately, I don't think it's a bug either. What doesn't make sense to me is that the entire screen needs to have these washed colors for the fingerprint sensor to work. It's such a small part of the screen, why wash out everything?
I saw it too. I was using Advanced Color Gamut option. Then I switched to "Saturated" and it solved it.
Unfortunately that didn't work either.
Strange thing is that it doesn't happen on my 9T Pro.

I have no idea why tho.. Im guessing maybe it have something to do with "Sun mode" kinda "overclock" the entire display when fingerprint-reader need to, and then switch back to normal display mode right after.
But that kinda defeats one of the OLED key-strength, being able to lights-up individual pixel instead of lighting whole screen. Doesnt make sense to me either..
We need to report this from the miui developer guys its so annoying especially when you're in a dark room or room with lights off

If you used other Xiaomi devices you'd know it didn't happen before.. I hope it's not a hardware thing.
Disabled my fp at least for now. Can't enjoy a brand new phone with these washed out colours.
Ahhh. So it's not just mine lol. I played with so many different settings trying to fix this crap. I gave up lol

I agree with you, as this behaviour didnt happen on my Mi 9T Pro, although I suspect it could have caused by both "sun-mode" and Xiaomi decision to use white-light for fp illumination instead of turquoise-like color on previous model. Im still using it, for convenience anyway.
In my experience it is just happened with gamut color option, with other color option it is no issue. My super mars wallpaper look amazing.
hi guys !!
i am still observing screen flickering issue on poco X3 (after update) but it is only observable while using 'material island live wallpapers' or 'live wallpaper from google wallpaper'
what i observe is
1. screen tone change to yellowish (have to on and off night mode to get it to normal)
2. continuous screen flickering if i pay attention to it (observable on dark sides)
plz comment if any of you having same issue with this device or u already resolved it.
i am having poco x3 India varient screen is same on both
update ::
flickering + screen tone change is observable on two apps yet material island app and google live wallpaper ( both have same live wallpapers)
where as screen tone change on opening ANY live wallpaper app (when i am just going to apply it)
already done that google chrome method.
I have similar problem but with browsing the web. Few days ago Xiaomi share new rom update, after that everything works correcly.
I have been using poco x3 the global variant for 2 weeks now, i also use the material islands live wallpaper but i havent noticed any yellowing or flickering so far, maybe the unit you have is faulty?
Hi
Did you try to change "Settings/Display/Scheme Color" to "Standard" ?

Thanks for reaching back, i think this was issue in Indian variants i contacted service center guys they assured me to wait for updates as except few specific apps everything is fine. After update i didn't notice any such yet, as i did notice in previous update.

Oh okay that's perfect then. Since 732G is a new chip and is released alongside poco x3 thus optimizations are needed. I'm very positive regarding future updates

Yeah doing that bring back phone to normal. But after opening that app again problem used to re appear but now after update i didn't encounter previous problems yet.
Help I have screen flickering issue when manually changing brightness to minimum in a dark room (auto brightness disabled in settings). Anyone else experience this type of flickering?
EDIT: I just came across this possible solution to my specific screen flickering problem:
