If we drag the bar to the left of the screen, the display will be reduced to the halfway point, making it much easier to operate it with just one hand.
Extra Dim Features
A feature similar to that of Dark Mode 2.0 was added in MIUI 12 in the past. This feature has now been reinstated by Google, ported to MIUI, and works quickly. In sync and with the Android system, it will remove the issue of putting a black screen display when taking an image before taking. Google has added it to Android 12.

Final Words
If you are in Stock firmware, Use the Internal memory or Stock recovery-based method. It is comfortable and safe; You can update it like a Regular OTA Update. But if you were already using Rooted devices, You can try TWRP based method. Don’t download any third-party apps; sometimes, it may trigger the updates process. There are a lot of new Gestures available in this update; try them also. In my opinion, When you hate MIUI, You can try to root your Xiaomi Redmi K50 Ultra 12.4 Android 12 and install custom ROMs. They are better compared with some other Custom Skin OS. But the new MIUI is better. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
