For all with deep sleep problems.. open Apps in settings, then tap "Manage apps", tap on the three dots in upper right corner and choose "Show all apps". After that search "In-Display Fingerprint", tap on it and delete all data from this app. At least for me this helps, for a few days already
Reported already or not, but cannot access phone information (tap 4x on the "Internal storage" in phone specs). Phone information 1 and 2 are crashing and for a few seconds network will be lost. Mi9 9.8.10 version. Is it known bug or only me?
