Excuse me, are you talking about the personalized signature of the lock screen wallpaper? After you light up the screen, hold your finger under the dividing line above the nickname for 1-2 seconds, slide down, a row of pictures will come out, turn the page to the left, and click the+box to set it.

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!
