What should I do if I can't remember the SMS password of vivo x5pro? How to get it back?

Answer: There is no default password for SMS password. The password set for the first time is the original password. If you forget to set the password, you can use the vivo assistant to back up the relevant data on the computer side, and then go to the phone "Settings-> General->; Restore factory settings-> Clear all data "to delete SMS encryption. (Note: This operation will lose all the data on the mobile phone, including the phone book, SMS and installed third-party programs, which need to be backed up in advance. The data on the TF card will not be lost. )
