Here are some popular FAN VPNs that are known to work well on Android devices:

It seems like you're asking for a FAN VPN, but FAN is a browser-based VPN service (now known as FAN VPN) that is primarily used through web browsers. If you're looking for a VPN application for Android devices, there are several reputable VPNs available that are mobile-friendly and provide similar functionality.

1. FAN VPN (Web-based, not mobile): As the original developer, FAN is primarily used through web browsers. However, there is a web-based FAN VPN application available for Android users.

2. FAN VPN (Mobile-based): Some users have developed mobile-based FAN VPN apps, though these may not have the same level of security and may not be as reliable as the web-based version.

3. VNC Instant VPN (Android): This is a well-known and widely used VPN application for Android devices. It is lightweight, fast, and has a user-friendly interface.

4. FAN VPN (Mobile app): Some users have created mobile apps that are clones of FAN's VPN functionality, but they may not be as secure or feature-rich as the web-based version.

5. VNC Pro VPN (Android): Another lightweight VPN application for Android users, known for its speed and ease of use.

To find the best FAN VPN for Android, I recommend checking out the latest versions of these apps or cloning FAN's web-based VPN functionality into the Android ecosystem. Additionally, you might want to consider FAN's FAN Proxy Server, which is a popular VPN proxy tool for use with other VPNs.
