Trigger: System Setting Change

This trigger will fire when a system setting from the device's system, secure or global settings table is updated. This allows you to react to changes in Android system settings made by the user or other applications.

Options

• Setting Tables: Select which settings tables to monitor:
  • System: General system settings (e.g., screen brightness, font size)
  • Global: Device-wide settings that apply to all users (e.g., airplane mode, Bluetooth)
  • Secure: Security-related settings (e.g., accessibility services, location providers)

• Setting Pattern: Optionally specify a pattern to match specific setting names:
  • Leave empty to trigger on any setting change in the selected tables
  • Enter a specific setting name to only trigger when that setting changes
  • Supports Magic Text for dynamic pattern matching

• Enable Regex: When enabled, the setting pattern is treated as a regular expression

Local Variables

This trigger provides the following local string variables:

• system_setting_category: The category of the setting that changed ("System", "Global", or "Secure")
• system_setting_key: The name/key of the setting that was modified
• system_setting_value: The new value of the setting

Configuration

A searchable dropdown is provided showing all available settings on your device, organized by their current values and categories. Selecting a setting from the list will automatically populate the pattern field and select the appropriate settings table.
