How does Xiaomi 1s mobile phone back up short messages locally?

This requires the help of third-party software. You can download a computer version of the application treasure, connect the mobile phone and the computer with a data cable, open the mobile phone system, and set the developer option USB debugging. After the connection is successful, if the landlord needs to check it, export it in my mobile phone short message. After exporting, you can check it, and you can specify the path yourself. It is also possible to import it into the mobile phone in the future. If you don't need to check, you can use the data in the toolbox for backup. This can back up the short message to the backup package. Hope to adopt.
