To use a VPN on Android, first get an Android-compatible client and your subscription details. Import the subscription into the client, choose a route, and approve Android’s VPN connection request. Once connected, check your exit location and DNS, then address any background battery restrictions. Avoid changing every network setting at once: following this order makes it easier to identify where a problem occurs. Menu names vary between Android versions and manufacturers, so the guide also describes what to look for on each screen.
Before Installing, Understand Clients and Subscriptions
A client is the app on your phone that establishes the connection. A subscription contains route configurations provided by the service, usually as a link or through an import option in the client. Installing a client does not automatically give you a usable route; having a subscription link does not mean you can open it in a browser and connect. First, visit the VPNND client download page to find the Android download method, then get your subscription details as instructed in the panel.
Android’s system settings may also have a “VPN” menu, but it is mainly for manually configuring VPNs supported by the system. It will not automatically recognize subscription links for Shadowsocks, VMess, Trojan, VLESS, Hysteria2, or TUIC. For these subscriptions, import them into a client compatible with the format instead of pasting the entire link into the server address field in system settings. Check the options shown in the client to confirm which protocols, subscription formats, and split-tunneling features it supports.
| What You Have | Where to Go | What to Check First |
|---|---|---|
| Subscription link | Subscription import option in a compatible client | The link came from your service panel and the client supports its format |
| Single route configuration | Manual import option in a compatible client | Protocol, address, authentication details, and other fields match the supplied configuration |
| System VPN configuration | VPN menu in Android settings | The configuration type is supported by Android and is not a client-specific subscription |
From Import to Connection: Follow the Screens
The steps below cover a common subscription import process. Buttons in an app may be labeled “Subscription,” “Configuration,” “Import from link,” or “Add.” The exact wording may differ; what matters is that you can see selectable routes in the app after importing. If the VPNND panel provides a dedicated import method within the client, follow its instructions first rather than adding the subscription manually again.
- Install and open the client.Use the download link provided in the VPNND panel, install the app, and open it. On first launch, you may see notifications or battery-related prompts. First make sure the app opens to its main screen; handle network permissions and background settings separately later.
- Import the subscription.Copy your subscription details from the service panel, return to the client, find its subscription import option, paste the details, and confirm. If the client reports a “format error,” check that you copied the full content and that the client supports the subscription format. Do not guess which fields to use by editing the link.
- Update and choose a route.After a successful import, the client usually displays region or route names. Choose an exit that fits your needs. If you are unsure, connect to one route and verify it before comparing others. Visit the servers page for information about regions and route types, but remember that the listed regions do not guarantee the same configurations will be available in your client.
- Connect and approve the system request.Tap the connection control in the client. Android will show a system confirmation dialog for the VPN connection. Confirm that the request came from the client you just opened, then allow it. A connected status or VPN icon in the system status bar indicates that a tunnel has been established; you still need to verify the exit and DNS separately.
If no system confirmation appears when you tap Connect, check whether another VPN app is already using the system connection, then return to the current client and try again. Android typically manages one active VPN connection at a time. Turning on connection switches in multiple clients does not make them run together automatically. Disconnect the existing connection before switching apps to make it easier to identify which client is active.
Battery Settings: Prevent Disconnects When the Screen Is Off
Some phones aggressively restrict background activity when the screen is locked. You may find that the connection works while the screen is on, but the app disconnects after the phone has been locked for a while or reconnects only after you reopen the client. In this case, open “Apps” in system settings, find the client you use, and check options such as “Battery,” “Background usage,” or “Battery optimization.” Allow background activity or exclude the app from its battery restrictions. Options vary by manufacturer. If you cannot find a setting called “whitelist,” look for background activity and battery optimization controls rather than following someone else’s exact menu path.
After changing the settings, keep the connection active, lock the screen, then unlock it and check the client status. Test the target website again as well. If the app says it is connected but websites will not load, the route, DNS, or split-tunneling rules may be at fault; do not assume every issue is caused by battery settings. If your system offers an additional “Always-on VPN” option, understand how it affects network access after a disconnect before enabling it. Beginners do not need this setting to establish a basic connection.
- ✅ The client opens, and the imported subscription shows routes rather than an unresolved link.
- ✅ When connecting, you confirmed that Android’s system VPN request came from the current client.
- ✅ After locking and unlocking the screen, the client still shows the expected connection status and the target website loads.
- ✅ The exit region matches the selected route; if you use split tunneling, the target app uses the expected exit.
How to Verify Your Connection
Check the tunnel connection, exit location, and target app access separately. Before connecting, note the usual network exit information. Then connect to a route and use a trusted IP lookup page to see whether the exit region changes as expected. Next, open the target service in the browser or app you plan to use. If the client says it is connected but the exit remains on your original network, check whether split tunneling is enabled for only some apps. The browser used for testing may not be included in the rules.
DNS determines where domain names are resolved; it is a separate check from which route a web request takes. Use a DNS test tool to observe the resolver being used, then compare it with the client’s DNS settings and split-tunneling policy. If DNS information shows a different region, do not conclude that there is a leak based on the place name alone. First check whether the tool is showing a DNS resolver, web exit, or local network information, then consider whether the target app works as expected. After changing DNS or rules, reconnect and repeat the same tests so you are not comparing results from different settings.
Split tunneling typically directs traffic based on domains, addresses, or apps. “Global” mode generally sends all test traffic through the client. “Rule” mode lets you select routes based on the destination, but requests not covered by a rule may follow the client’s default policy. To troubleshoot one app, temporarily use a clearly defined mode supported by the client to verify that the route works, then return to rule mode and check where that app and its related domains are routed. Labels for “direct,” “proxy,” and default rules vary between clients; check the app’s documentation.
Troubleshooting: Find the Failing Step Before Changing Settings
Import fails: Check that the link is complete, that you did not copy extra spaces, and that the client supports the subscription format. If the route list is still empty after updating, return to the panel to get the details again, then trigger an update in the client. Do not mistake a local configuration path generated by a client for a subscription link from the service panel.
You can select a route but cannot connect: First confirm that your regular network can open common websites, then test other routes in the same subscription. If routes behave differently, the issue may be specific to an exit or transmission path. If all routes fail, check the subscription, client permissions, and local network. An IEPL dedicated line, a relay, and a direct connection describe different routing paths. A dedicated line or relay may change how some network segments carry traffic, while a direct connection reaches the route entry point through the current network. The name alone does not guarantee that a region or app will work; test it on your current network.
The client says connected but the target service is unavailable: Check whether the exit matches the region required by the service, then review split tunneling and DNS. If common websites load but a particular app does not, check whether the app uses its own network settings or is excluded by the client’s per-app rules. Note your current settings, change one item at a time, and repeat the test. This makes the cause easier to find than changing the protocol, DNS, route, and rules all at once.
The connection drops only when the screen is locked: Review battery optimization and background activity settings, and check whether the system restricts the app in battery saver mode. If the client provides connection error details in its logs, use them to identify authentication, resolution, or timeout issues. Hide subscription addresses and other credentials before sharing logs. If the cause is a background restriction, adjust the battery options; reinstalling the app repeatedly is unnecessary.
