What should I do if I forget the password for the encrypted SMS session on my VIVOS6 mobile phone?

Hello! If there are important text messages or phone numbers in your mobile phone, you can use the vivo assistant on the computer to back up the relevant data, and then go to the mobile phone "Settings-gt; General-gt; Restore factory settings-gt; Clear all data" to clear it Password, this operation will lose all data on the phone, including phone book, text messages, and installed third-party programs. The data on the TF card will not be lost. If there is no data in your phone that needs to be backed up, you can clear all data directly on your phone.
