This problem is familiar to many owners of smartphones on MIUI, and the reasons can be very different, from a trivial synchronization failure to serious errors in the operating system.

Unlike iPhones, where contacts are securely tied to iCloud, on Android devices (including Redmi Notes) 10/11/12, Redmi 9/10 and other models) data are often stored in several locations: SIM-It's in a map, in a Google account, in a Mi Account cloud, or locally in your phone's memory, and it's this fragmentation that often causes them to disappear suddenly.
