question: Network protection for Android: Keep your internet safe when VPN drops
answer: 
  A VPN helps secure and anonymize your network traffic. If your VPN unexpectedly disconnects, the ExpressVPN Android app’s network protection feature will automatically blocks your internet. This keeps your data safe by preventing unencrypted data leaks.
  
  Network protection vs Android system settings
  
  While ExpressVPN’s network protection gives sufficient protection to your online traffic, you can enable a setting via the Android system settings that gives you full data protection. However, this setting will block access to local devices. This setting is also not available on Android TVs and Fire TVs.
  
  Important: If you have general connection issues, refer to other troubleshooting guides.
