RedTrigger Automation app for Android description
RedTrigger enables shoulder triggers (SAR capacitive sensors) on Nubia Red Magic phones system-wide, without needing Game Space.
Nubias game framework controls the shoulder trigger hardware and only activates them inside Game Space. The system also resets trigger settings every time you switch apps. RedTrigger fixes both issues.
How it works:
- Activates SAR sensors without launching full Game Space
- Runs a watchdog service that detects when Nubias SystemMgr resets trigger settings on app switch
- Re-applies settings instantly, keeping triggers active across all apps
Key remapping (via Shizuku):
- Reads raw input events from /dev/input using a Shizuku UserService
- Optionally injects remapped key events (L1/R1) so apps like KeyMapper can capture them
- Uses a virtual uinput device so remapped events appear as real hardware input
Requirements:
- Nubia Red Magic phone (tested on Red Magic 11 Pro)
- Shizuku installed and running (wireless ADB or root)
The app automatically grants itself WRITE_SECURE_SETTINGS via Shizuku, so no manual ADB commands are needed. Enable Auto-enable on boot to survive reboots.
