How to cancel the password of SMS?

At present, there is no default password for smartphone SMS password, so encryption needs to set a password. If you set your password and forget it, you can use the mobile assistant to back up the relevant data on the computer side, and then go to 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.
