I really hope that some developer or moderator reads me.
since they released miui 12.5, multitasking (it will divide the screen in 2) has become unusable, the screen blinks a lot in black and the gestures to go home do not work, only back, and not to mention the gesture of switching applications, it is impossible.
I invite you to use those options and see that it is failing a lot and I hope that it can be used well as before.
In the first release of miui 12.5, the battery was incredible, it lasted a long time before charging, but since the second it no longer gives that performance, I don't know what could have been there.
thank you anyway to everyone and to the development team of the Mi 9 SE.
Cheers!!
