SMS is encrypted. How to cancel encryption? I don't remember setting the SMS password before. Is there any other way besides restoring the factory settings?

Hello! There is no default password for smartphone SMS password. You need to set a password for the first encryption. If you set your password and forget it, you can use vivo assistant to back up relevant data on the computer side, and then enter "Settings-"; General-> Restore factory settings-> Clear all data to clear the password. This operation will lose all data on the mobile phone, including contacts, information and third-party programs installed by yourself, and the data on the SD card will not be lost. If there is no data to be backed up in the mobile phone, you can directly clear all the data in the mobile phone to clear the password.

If you have any questions, please feel free to consult us. Thank you very much for your support of our vivo, and wish you a happy life!
