Hello, I am a Mi 11 Lite 5G user (bought in Spain, from Orange). I have a Tianma Screen and since I updated to MIUI 12.5 (yesterday) the screen looks even worse than before. Instead of dark tones I see big green pixels using my device in dark mode or watching series and movies during night. I have this issue in all color modes (including P3).

I just wanted to open this thread to report it and to know if there more users with this problem. I know at least 3 more users with this problem here in Spain

Green tint issues are among OLED screen for a long time, here as reference: https://forum.xda-developers.com/t/green-tint-on-screen.4262217/

Maybe Tianma has it even worse. Magnitude may be different between devices and screen.

If it's obvious, can try refund or replacement. Check your country Xiaomi warranty policy though. Sometimes after submitting replacement, even if you didn't get your replaced device, you will not be able to make refund.

@polfmarti I also have pixel clusters where there should normally be black shades. But I already had this problem with Miui 12. I thought it was a software issue, but maybe it's not? Btw i have Tianma display too....

Is the same for me. Tianma screen here too. I have the same issue but I don't know if this started with 12.5 update... I think this problem was here before tbh.

Is not only the green tint issue but also a "pixelation" (square artifacts) on dark scenes. They can be seen in movies, images, or even the UI.

It is not pixelation but in line with Black Crush problem that plagued Samsung S9.
I have Tianma panel too and had said black crush problems. But 12.5 seems to have fixed it.
I haven't done a throughout test but LG OLED test on Youtube does not show any symptoms unlike before.

And story continues. WTF Xiaomi, making bad things worse with software? They of course know about the issue and now trying to sort out **** display with software updates. No chance!

I'm in touch with them and answer was kind of "yeah, we know displays are meh" but not straighforward of course. Trying to change mine in UK for device with Huaxing. Will let know if will be succesful.

It's disgraceful to put those displays in Lite version of flaghip phone...!

Another new thing since the 12.5 update: Blacks are no longer black. They are clearly grey, deep blacks don't exist anymore (except during HDR Youtube videos, which proves that it's a bug again....)

Wtf Xiaomi ?

I fixed this by changing the color profile to p3, I had the exact same issue before.
Its under display settings and I attached screenshots.
