Why doesn't Xiaomi mobile phone share SMS and call records?

This is inseparable and must be shared.

The doppelganger system of Xiaomi mobile phone is equivalent to the privacy space of the mobile phone, that is, the storage space of a system is divided into different partitions, instead of brushing two different packages from two different partitions in underlying partition, like a dual system. Therefore, in terms of confidentiality, the mobile phone avatar is not as good as the dual system, but in terms of convenience, the mobile phone avatar has great advantages. In the address book, all the contacts have been emptied, but all the short messages and phone records are still there, but the names have become numbers and our notes are gone.
