SMS is encrypted. Forgot the password.

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 the vivo 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. The password to restore the factory settings of the mobile phone is the unlock password of your screen. If it still doesn't work, you can try recovery mode. I suggest you make a backup before operation: turn off the phone first, and then press and hold the "phone volume+button" and "power button" (also called power button) for 5 seconds at the same time. After the vivo mobile phone Logo appears on the mobile phone, release the button and enter the recovery mode. Select back up user data to back up user data, then erase data/restore all data after leaving the factory/restore user data, and then select restart the system immediately. After the interface jumps, restart the phone.

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