zFont

Appearance

Vivo phones don't normally allow custom fonts and themes from outside sources. This guide shows you how to work around this limitation using special apps and a step-by-step process.

Important: This method requires patience and careful following of steps. It's currently the only way to use custom fonts without downgrading your Themes app.

Why Do We Need This? ​

The Problem ​

  • Old Vivo phones stored themes in a folder you could access: /sdcard/.dwd/c/o/m/b/b/k/t/h/e/m/e
  • New Vivo phones (Themes app version 7 and newer) store themes in a protected folder: /data/bbkcore/theme/.dwd
  • Regular users cannot write to this protected folder
  • Only special Vivo system apps can access it

The Solution ​

We found 2 Vivo apps that can access the protected folder:

  1. Vivo File Manager
  2. Vivo Documents

Using these apps, we can modify downloaded themes with our custom fonts.

Remember

This method exists because Vivo doesn't officially support custom fonts. The best long-term solution is to ask Vivo to add official support for custom themes and fonts.
