should be great.... I love built-in solutions...But for future version of miui it will be great a better backup software.
??? Yes, you can. In the actual new version, SMS and MMS are a different backup from both Contacts and Call Records.In new version of miui backup you can't backup and restore SMS and CALL LOG without restoring contact in the same time.
In version before 1.1.21 you can backup and restore SMS and CALL LOG alone.
