Systemless Module Guide Advanced

zFont 3 supports creating systemless font modules for advanced users to flash through Magisk, KernelSU, or APatch. Since some Android manufacturers restrict custom font changes, you can use this method to change any font and emoji on Android devices. This method will change all system fonts across every app.

Important

This guide is for Advanced users only. If you are not familiar with ROOT, we do not recommend using this method.

Important considerations:

• ROOT will void your device warranty
• Always backup your data before proceeding
• Ensure you understand the risks involved

Create Emoji Module

Creating an emoji module is straightforward:

1. Click the Create Module button
2. zFont 3 automatically handles all module creation steps
3. No additional configuration required

Create Font Module

Font module creation depends on your target language and requires proper font mapping.

Basic Font Mapping

For English fonts, map your custom fonts to the corresponding system fonts:

Your Font File	Maps To System Font
MyFont-Regular.ttf	→ Roboto-Regular.ttf
MyFont-Bold.ttf	→ Roboto-Bold.ttf
MyFont-BoldItalic.ttf	→ Roboto-BoldItalic.ttf
MyFont-Italic.ttf	→ Roboto-Italic.ttf

Important

Mapping only Roboto-Regular.ttf will not change fonts system-wide. You must include all font styles (Bold, Italic, BoldItalic) for complete font replacement.

Language-Specific Fonts

For non-English languages, use the appropriate system font family:

• Myanmar: Use NotoSansMyanmar family
  • Replace -Regular.ttf with your Regular variant
  • Replace -Bold.ttf with your Bold variant
• Other languages: Check your system's font directory for the correct font family name

Font Mapping Examples

Complete English Font Set:

MyCustomFont-Regular.ttf → Roboto-Regular.ttf
MyCustomFont-Bold.ttf → Roboto-Bold.ttf  
MyCustomFont-Italic.ttf → Roboto-Italic.ttf
MyCustomFont-BoldItalic.ttf → Roboto-BoldItalic.ttf

Myanmar Font Set:

MyFont-Regular.ttf → NotoSansMyanmar-Regular.ttf
MyFont-Bold.ttf → NotoSansMyanmar-Bold.ttf

Installation Process

Method 1: Direct Flash (Basic)

1. After creating your module, click Flash in the dialog
2. zFont 3 will install the module directly

Method 2: Module Manager (Recommended)

1. Create your module in zFont 3
2. Open your root solution manager:
   • Magisk Manager
   • KernelSU Manager
   • APatch Manager
3. Install the module through the manager
4. Reboot your device to apply changes

Recommendation

Using a module manager provides better control and easier management of your font modules.

Post-Installation

After installation and reboot:

• Check if fonts display correctly across all apps
• Verify all font weights (Regular, Bold, Italic) work properly
• If issues occur, ensure all required font variants were mapped correctly
