How to set mobile wallpaper for vivo mobile phone

If you refer to the call background, you can set it as follows:

Non-Origin OS system: open the contact-click the contact stored in the mobile phone (the contact stored on the SIM card does not support it)-click the avatar-select photos or take photos from the album-and then the photos set during the call can be displayed as the background of the call. If no contact photo is set, desktop wallpaper will be displayed in the background of the call. Just change the desktop wallpaper, and then go to my theme-My wallpaper to make changes.

Origin OS system: Desktop wallpaper is displayed by default in the call background. If you need to change it, just change the desktop wallpaper and go to My Theme-My Wallpaper to change it.

Tip: The call background is blurred.
