VPN Android Always-On

Always-On VPN on Android forces your device to keep the VPN active whenever possible and can block all connections if the VPN is not running. When combined with “Block connections without VPN,” it behaves like a strong system-wide kill switch, preventing accidental leaks during app startup, network transitions, or brief disconnects. This is particularly valuable for users who roam between Wi-Fi networks, travel frequently, or rely on VPN for location privacy. Always-On can slightly increase battery use because the VPN may reconnect more often, but modern protocols like WireGuard minimize the overhead. It also improves discipline: you don’t forget to turn the VPN on. If you use split tunneling, understand which apps are exempt and whether Always-On still blocks everything else. Always-On is a best practice for high-risk sessions, but it can break captive portals and some local services until you temporarily disable it. In DVPN clients, Always-On ensures traffic consistently uses the chosen nodes and reduces “oops” moments where your phone briefly sends traffic outside the tunnel. Test behavior after OS updates and verify DNS leak protection remains enabled.
