v2rayN vs. v2rayNG
and v2flyNG

v2rayN is a good fit for desktop users who want to manage server lists and subscription groups, edit routing, and review core logs in one place. Importing a subscription and selecting a server doesn't automatically route your browser through the proxy: check the system proxy setting in the status bar, too. A common starting point is “Set system proxy” with the “Bypass mainland China (Whitelist)” routing mode. The first controls which apps use the client; the second controls how their connections are routed.

If you regularly edit rules such as geosite:cn and geoip:private, the desktop interface makes it easier to check their order and outbound tags. However, seeing proxy, direct, and block in a table doesn't mean every custom configuration uses those same tags. Check the generated config. Rules are matched from top to bottom, so specific exceptions often need to be checked first.

The Windows download page offers a desktop edition and a classic WPF edition. The desktop edition uses a cross-platform interface; the WPF edition retains the classic desktop workflow. Choose based on OS compatibility and the interface you're familiar with—not as if these were different protocols. On macOS and Linux, use the release for your system. TUN support also depends on permissions and runtime components.

v2rayNG brings the usual connection steps together on your phone: import a share link or subscription URL, update configs, select a server, start the connection, and authorize Android's VPN service. It's usually the first choice on Android for users with Xray-based configurations. Names such as VLESS and Trojan describe only part of a config; the transport, TLS, or REALITY settings must also match the server.

Android handles traffic differently from desktop. Once the app starts its VPN service, the system routes eligible traffic through the client; per-app routing lets you control which apps are included. If an app still connects directly, check whether it's excluded, then review routing and DNS instead of repeatedly switching between copies of the same subscription. Another app using Android's VPN service may also prevent the connection from starting.

For everyday phone use, background battery restrictions are often more important to check than interface features. If the connection drops when the screen locks or after switching networks, check background permissions and logs. Installers may be available for arm64 or as a universal package; arm64 is usually the best choice for newer mainstream devices. If you're unsure about your architecture, check the download page. Package size doesn't predict connection performance.

Choose v2flyNG for its core, not because an older phone will automatically run better with it. It's intended for the V2Fly ecosystem. If you already have a config that works with V2Fly or need to check specific V2Fly core behavior, consider it as an Android alternative. A similar interface doesn't remove differences between cores, so check the config fields and supported features after importing.

Be sure to distinguish subscription contents from the client's interface: a subscription may contain several types of configs, and seeing a name in the list only confirms that some of it was parsed. If a feature requires Xray, don't force the config to start by deleting fields that cause errors; doing so may change the security or transport requirements for the connection. Ask the configuration provider for a working V2Fly config before choosing this client.

Assess maintenance separately, too. An update to v2rayNG doesn't mean v2flyNG has gained the same features. Before installing, check its release notes, system requirements, and bundled core. During use, note errors you can reproduce. Android users who mainly use Xray configs and don't specifically need V2Fly will usually find v2rayNG easier to troubleshoot.
