vivo & iQOO Limited Support

zFont 3 is only guaranteed to support devices running Android 11 and earlier. On Android 12 and later, zFont may not work reliably on vivo & iQOO devices.

For devices running Android 10 and later, you will need to downgrade your Themes app. To do this, refer to the Downgrade guide.

For Android 12 and newer devices, try the File Manager & Documents method to apply fonts and themes on vivo & iQOO devices. Please note that this method is not guaranteed to work on all devices.
