Surfshark has discontinued support for the Android 5.0 (Lollipop) operating system. Users are encouraged to upgrade to at least Android 6.0 to continue receiving official app support and security enhancements. The decision is part of Surfshark's strategy to focus on modern security standards and advanced features like post-quantum encryption, which cannot be securely managed on older Android kernels. Manual connections are still possible for legacy hardware, but upgrading is strongly recommended.
