How to change the personality signature of vivoxshot mobile phone

Excuse me, do you mean the personal signature or the personal signature of the screen lock interface?

In the lock screen interface, tap the nickname avatar with your finger for about three seconds or hold down the thumbnail to drop it down. After entering the editing state, click the leftmost "+"to change the nickname avatar and personalized slogan! (The two methods are because the unlocking styles are different and the methods are different).

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!
