Maybe something wrong with your display?
Are you using a custom ROM, or do you have any Magisk Modules?
If no, then it is probably a display issue.
You could try to flash the stock firmware, or factory reset.

No in my phone I will use the stock oneui rom
If I install custom rom it the display is normal but in oneui when fingerprint will add then display problem will occur otherwise the display is good as normal

There is definitely something wrong with your display, and I don't think you can fix it without a replacement. Sorry, but I really don't think there is anything you can do other than replacing it.

Its normal!
I thought of its normal on all device!
When i applied my custom wallpaper on lockscreen i slightly noticed its color is different from original pic so i changed pic and applied some dark wallpaper and now its fully green , it can be noticed easily!
You can remove fingerprint sensor (which i do)
Or
Use perfect wallpaper or use samsung wallpapers!

Ah okay, I never noticed that. Thanks for telling me about it!

There's nothing wrong with your display. Its a bug and a lot of ppl have it, including me. It happens with the lockscreen with inscreen fingerprint. In my case, if i rise the brightness it fixs but only for a while. Probably the next update will fix it

Hallo i think this is problem with oneui in lower Brigthness sceen show green tint on lockscreen with fingerprint and screen has buggy when call or alarm start

Screen Burn Issue [Potential Fix] [Moto G4 Plus]

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 .

S7 Strange Screen Flickering

So I bought my used S7 recently, the device seems to be totally clean not even a scratch on the frame, looks like brand new and even the software status is OFFICIAL not even the Knox is tripped.
I found a thread on XDA about using an updated version of TouchWiz Home of the S8 for the S7 by installing the APK.
it worked like a charm until I started to change my wallpapers and notice something strange.
im using an application to change the wallpapers auto every 5 minutes, the problem is whenever the wallpaper i use has some bright colors like bright purple or bright red and i press the app button to access the app drawer those colors (ONLY) flicker , they flicker just before the screen get blurred and take u to the app drawer, and also when u go back to the main screen from the app drawer also right after the blur disappear.
i got scared so i uninstalled that Touchwiz Update and came back to stock, to notice that the problem is still there, but its not as noticeable as the s8 TW
i wanted to know if the screen is dying or this is something normal, and also wanted to know if its a software related problem or hardware one, and finally if someone is having the same issue ( i can share a wallpaper if anyone is willing to try wit it )
NB: the screen flicker ONLY ON THE BRIGHT COLOR before the blur effect happens and After it.
Thank you all in advance & i apologize for my English
I made this video If you focus on the second time especially ( when going to the home screen from the app drawer ) you can see clearly the red rose flicker. Sometimes the flickering is harder depending on how bright is the color.

This can only be a software problem, because its also visible in the Video. Your screen is not damaged, and it will not be damaged. This issue is not a problem, maybe only a bit annoying.

It is so annoying for me cuz i had an old S5 plus that ended up with the screen flickering so whenever i see it flickering i got a heart attack.
Is there anyway to fix it i tried factory reset but nothing changed..
Thank you anyway for replying
I think thats a Problem with the Launcher. I've tried it on my Phone, and it is also flickering. You can try to speed up the Animation-Speed in the Developer-Settings. Maybe then you wont see the flickering.
You can see it here, that it is also on my phone: https://photos.app.goo.gl/nYKM5ss9EKe3L0M43

Thank you very much !!!! You have no idea how much its relieving to know that this problem is not only present in my device.
For now ill just stay away from bright wallpapers until hopefully Samsung will make fix for this issue.
Thank you again !
EDIT : after i came to the pc and i saw the GIF u made i noticed that we dont have the same flickering , maybe the quality of the GIF wasnt high enough but for me it didnt seem to be te same, so i will ask you one last time when you tried that wallpaper did it show the SAME result as my video for u ?
thank you in advance

OOS Stable Pie : screen calibration randomly goes back to default?

Hi guys,
I'm running OOS Stable Pie on my OnePlus 6. I know I'm also running Magisk and a custom kernel (blu spark) but I don't know why it would have to do with my issue. It also happenned to me with Radioactive kernel.
So basically, randomly, when I wake up the screen, I can tell the screen tones have changed and when I go to settings, I can see that "srgb" is selected, however, if I select "default", then the colors don't change, and then if I select "srgb" again, then the colors go back to what I picked earlier, before turning on the screen.
It happenned to me a few times now, and I think it always happens after waking up the screen. I don't think it happens while the screen is on.
I didn't change any display settings in kernel apps such as Kernel Adiutor.
Am i the only one affected by this bug? Is this known? Is there a fix that should come?
Thanks for your help.
Up
same here
both OOS and HOS 9.0

Thanks for reporting the same bug. it's kind of reassuring that I'm not the only one affected. So we can hope for a fix for next update! It really makes my eyes bleeding back to default settings

Colors Washed on Lock Screen when Fingerprint Unlock is Enabled

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.

Question Wallpaper blinks black once if phone is unlocked from Moto Display? [Android 12]

I'm on Android 12 and among many unpleasant things about this update there is one very irritating.
If I'm unlocking phone from Android 12 Lockscreen then it's unlocked like usual.
If I'm unlocking phone from Moto Display, then for a split second homescreen wallpaper (icons are unaffected by the way) turns black.
Is this a know bug on Edge S or it's just me being unlucky?
I dont have that problem. I do recomed try with a hard reset

Yeah, gotta give a small update on this issue. This problem occurred shortly after I've upgraded to a12. For whatever reason I had two lockscreens (a12 and moto display) interfering with each other. One time you'd get a12 and the other - moto display. Then I set up a pin and a fingerprint, then removed them both and the a12 lockscreen has gone as well.
Now I'm trying to understand why the a12 lockscreen is gone and how to recreate this issue. At the moment I have only moto display. Do you still have both moto display and a12 lockscreens?
