Miui 13 with A12 updated from Miui 12.5 A11 with the fastboot variant.
Only the "abdate version" used, all data was retained.
so far very satisfied, only whatsapp I had to reinstall because of malfunction.
update 12.10.22: update: the smartphone always starts 2x during a self-initiated reboot
a google play system update is displayed. if this is installed, a newer date appears after restarting.
then the phone restarts by itself and then the old date from the system update is there again and the same update is displayed again.
does anyone know the problem?
