Nugon SOS v1.1 - Versión Inteligente
Nugon SOS is now technically mature, offering a seamless user experience while maintaining robust emergency detection even in the most restrictive Android environments.
Final Optimizations
1. Intelligent "Stealth" Mode
To solve the issue where Nugon SOS would show a "Remote Screen" volume icon during normal use, I implemented a screen-state aware engine:
- Dynamic Bypass: The
MediaSessionandSilent Audioloop (needed to bypass deep sleep) now only activate when the screen is OFF. - Transparent UX: When the screen is ON, the app releases control, allowing the standard Android volume UI and icons to work normally.
- Background Persistence: The
AccessibilityServiceremains active at all times, providing seamless transition and constant monitoring.
2. Haptic Language Refinement
Corrected a critical bug where diagnostic vibrations would loop indefinitely.
- Single Pulse Feedback: The app now gives exactly one short pulse (50ms) when the user starts pressing the button, serving as a silent confirmation that the interaction is being tracked.
- Clean Countdown: The 1.5-second hold period is now completely silent, followed by a clear, 1-second confirmation vibration once the alert is dispatched.
3. Volume Passthrough
- Fixed the volume hardware lock. Nugon SOS now programmatically passes volume adjustment requests back to the system. This ensures the user can still change their phone's volume while protected.
- Implemented a Recursion Guard to prevent the app from triggering its own volume listeners, ensuring stability.
Verification Summary
Manual Reliability Check
- Normal Use: Volume buttons show standard icons and change sound correctly.
- Deep Sleep: Device on battery, screen off for >30s. Long-press triggers SOS correctly after the first 50ms vibration.
- Continuous Support: The "Nugon SOS Activo" notification remains persistent and functional across multiple alerts.
The application is now ready for production-level use.
