Secure Lockscreen Camera

Xposed Framework module to skip authentication on "Quickly open camera" gesture.

Requirements

• Android 11+ (other versions not tested)
• Riru
• LSPosed (EdXposed not tested)
• ANXCamera or GCam port (other cameras not tested)

Installation

1. Install latest version of Magisk
2. Install Riru and Riru LSPosed from Magisk module repository
3. Install Secure Lockscreen Camera package
4. Enable module in LSPosed app with recommended scope, reboot

How does it work

This module patches two classes to achieve it's goal:

• com.android.camera.Camera to draw activity over lockscreen without invoking Keyguard.
• com.android.server.GestureLauncherService to create custom intent for this activity.

Thanks

• Author of original Enable Camera on Lockscreen module with the same functionality but written 9 years ago.
• LSPosed Telegram group for valuable advice.
