  * File: static/js/android_location_handler.js
  * 
- * This module addresses Android-specific geolocation issues:
+ * This version includes only precise location methods:
- * 1. Android Chrome timeout handling
+ * 1. Progressive GPS fallback (4 attempts)
- * 2. Progressive fallback strategy
+ * 2. IP-based geolocation (3 services) - 5-50km accuracy
- * 3. Enhanced permission detection
+ * No timezone analysis (removed 100km accuracy method)
- * 4. Network location fallback
- * 5. Multiple retry attempts with different configurations
