Vivo mobile phone short message is accidentally encrypted. What if I don't know the password?

According to your description, it is suggested that you put your phone into Settings-More Settings-Restore Factory Settings-Clear all data. Clearing data will lose data. It is recommended that you make a good data backup before cleaning. If it doesn't work, I suggest you try mobile phone double clearing. When the phone is turned off, press and hold the volume increase button and the power button at the same time. After the logo of vivo phone appears for 3 to 4 seconds, release the button to enter the recovery mode. First, select Erase Data/Restore Factory Settings, wait for the interface to jump, then select Erase Cache Partition, and then select Restart the system immediately to restart the phone immediately.

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!
