I have some good news ( maybe ).
Here is the result, so far so good, no any laggy, random reboot or rotation issues, but I don't know it gets rid of them forever or not.
Actually, I follow the instructions mentioned before in this thread that is not to setup anything at the first boot up ( I suggest you to do the factory reset before flash latest EU rom to prevent certificated process ) and also ignore the notification that want you to finish the setup after you boot into MIUI.
After the process, you can reboot and checking if anything going wrong. If not, and you can open the google play store to login your google account and update everything. That's what I did last night, and it seems everything OK currently.
Combined with the voice match update issue, I think it maybe the reason, because what I did is actually bypass the voice match setting ( google assistance ). The others seems the same.
Hope these information will help.
