Another thing I've noticed after switching to Poco f1/Miui is the difference in lock screen notifications. When the phone is in standby and the screen is locked and off, on receiving a notification the entire screen lights up for a few seconds. This, I think is unnecessary. It would be nice to have just the time and notification visible in monochrome for a few seconds; the way it happens in android.
Also, the same behaviour is seen in "lift to wake" feature. Instead of having the screen light up in colour every time, it would be nice to have just the text light up in white against a black background.
This will save a lot of battery too, especially if you receive a lot of notifications.
