Hi all, I'm fresh owner of MI9, currently on MIUI 11.0.8.0 global. I'm quite satisfied with the phone, but one strange behaviour has been manifesting for a while.

If the phone is not on charger at night, it starts vibrating at 05:50:00 sharp everyday. Vibrations take ~10 seconds, then it stops. If the phone was on charger, it has not vibrated.

There is some exception in the log in mentioned time (below), but I'm guessing just correlation, not a cause of those vibrations. Any ideas what it could be?
