The key to setting up a VPN on Android is to check subscription import, permissions, and battery optimization separately. Seeing a route in the list only confirms that the configuration was loaded; seeing the VPN icon doesn't mean the target app is using an international route. Follow the steps in order—install, import, connect, keep the app running in the background, and verify the exit—to pinpoint problems more easily.
First establish a connection you can verify, then adjust advanced settings. Use the Android option in the service dashboard, import a subscription compatible with your client, allow Android to establish the VPN, and check the target app and exit route. Avoid changing the protocol, DNS, and routing rules all at once, or it will be difficult to tell which setting caused a change.
Before installing: understand the difference between a client, a subscription, and a route
The client reads configurations, establishes connections, and applies routing rules. A subscription link provides routes and related settings to the client. The route determines the path and exit used by the connection. These are different things. Android's “Add VPN” setting is not a universal subscription importer, so you can't paste a subscription URL into the system's server address field.
To use VPNEnd, start at the user dashboard. No email address is required; create an account with a username and password. After signing in, get your subscription and download an Android client from the download page. Don't install an app just because its name looks familiar, and don't look for replacement downloads in public comment sections.
If Android asks you to allow apps from this source, temporarily grant the permission only to the browser or file manager you're using. You can turn off installation permission for that source after setup. This is separate from the VPN connection permission you'll grant later; you don't need to enable developer options or obtain system-level privileges.
| Item | Purpose | What to check |
|---|---|---|
| Android client | Loads configurations, establishes connections, and applies rules | Obtained from the service dashboard or the project's official download page; supports the provided subscription format |
| Subscription link | Fetches the route list or full configuration | The link is complete, hasn't expired or been revoked, and is compatible with the client type |
| VPN connection permission | Allows the app to handle traffic through Android's VPN interface | The app named in the system prompt matches the client you're setting up |
| Background and battery settings | Reduces the impact of system sleep on the connection process | The client is allowed to run in the background and isn't restricted by battery optimization |
| Exit check | Verifies that requests are routed as expected | Check the IP address, routing scope, and target app together |
Import a subscription: check compatibility before updating the configuration
In the subscription section of the dashboard, use the copy or import option for your client. Different clients may accept different configuration structures: some subscriptions contain only nodes, while others include proxy groups, DNS, and routing rules. Even if they're all called “subscription links,” they aren't necessarily interchangeable.
- In the client, open the subscription, configuration, or profiles page and choose the option to add one by link. Labels vary between apps, so follow the interface you're using.
- Paste the complete subscription URL you just copied and give it a recognizable local name. Don't remove parameters at the end of the URL or add explanatory text.
- Save, then update or download the configuration. Wait until the routes or proxy groups appear, then set this configuration as the one in use.
- If the dashboard offers one-click import, make sure it opens the intended client. Check the result in the client rather than relying only on a success message in the browser.
Shadowsocks, VMess, Trojan, and VLESS are proxy protocols, not subscription file formats. A client that can read subscriptions doesn't necessarily support every protocol or transport they contain. If import succeeds but the client reports an unsupported core, check the client version and its supported protocols instead of arbitrarily changing the node's protocol name.
Subscription links usually contain access credentials, so treat them like passwords. Don't paste them into public conversion sites, group chats, or screenshots. If you suspect a link has been exposed, reset it in the dashboard if that option is available, then update your client.
For a “Download failed” error, first check your account and plan status, make sure the link is complete, and confirm your current network can reach the subscription URL. For a “Parse failed” error, check the format and client compatibility first. These errors have different causes, and repeatedly tapping Update may not help.
Grant permission: let Android handle the app's traffic
Choose a configuration and route, then start the connection. Android will usually show a VPN connection request, explaining that the app can monitor network traffic it handles. Check the app name and confirm. If you previously tapped Cancel, return to the client and start the connection again to prompt Android to ask for permission.
These clients often use Android's VpnService to create a virtual network interface, then process traffic through a local proxy core. The VPN indicator therefore means the interface is active; it doesn't confirm that the remote node, DNS, or every routing rule has been verified. Check the client's connection status alongside the results of actual network requests.
Android typically doesn't let two regular VPN apps use the system VPN interface at the same time for the same user or profile. Ad blockers, firewalls, and work-profile apps may also use it. If another app stops after you connect, check for an interface conflict. On managed devices, follow your organization's policies rather than trying to bypass restrictions.
If the app offers different modes, such as “in-app proxy” and “VPN mode,” beginners should follow the service guide and choose the mode that handles traffic from the apps they need. Starting a local proxy port alone doesn't mean other apps will use it. Android's “Always-on VPN” and “Block connections without VPN” are additional policies. The latter may leave your device offline if the VPN fails, so consider enabling it only after verifying the basic connection.
Battery optimization: prevent disconnects when the screen is locked
If the connection works in the foreground but drops when the screen is locked, check whether Android is restricting background processes. “Battery whitelist” isn't a standard menu name across all Android devices; the option may instead be called “Unrestricted,” “Allow background activity,” or “Battery optimization.” Open the client's app details in system settings, find its battery settings, and adjust the available options.
- ✅ In the client's battery settings, allow background activity or remove battery optimization restrictions for the app.
- ✅ If your system has a separate auto-start setting, allow the client to start as needed. This doesn't mean the client has automatic connection enabled.
- ✅ Check background data and data saver settings so the client can connect while in the background or when switching networks.
- ✅ If your device lets you lock an app in the recent apps screen, you can use that as an extra safeguard. Seeing the app card there doesn't guarantee that its process is still running.
- ✅ If the client requests permission for foreground service notifications, follow Android's instructions. Keeping the notification visible can help you spot unexpected stops.
After changing settings, connect and open the target app, lock the screen, then wake the device and check whether the connection is still active. Also switch once between Wi-Fi and mobile data to see whether the client reconnects. Change one type of setting at a time, and note whether the problem occurs after locking the screen, switching networks, or manually clearing apps.
Allowing background activity may use more battery, and it can't guarantee that Android will never stop the process. Force-stopping the app, restarting the device, and some manufacturers' cleanup tools can still interrupt the connection. If the client appears to be running after you wake the device but apps can't connect, check whether it reconnects after a network change instead of granting more system permissions.
Verify the exit: an IP change isn't the whole story
Before connecting, visit an IP lookup page and note your current network's exit location. Check again after connecting and compare the result with the selected route's exit information. Browser language, search result locations, and recommended content can reflect account settings or cached data, so they aren't reliable proof of your exit location on their own.
With rule-based routing, local lookup sites may connect directly, so seeing a local exit doesn't necessarily mean the VPN failed. Check which rule handled the lookup request, then open an app that needs an international route. If needed, temporarily switch to global proxy mode as described in your client's documentation, compare the results, and then restore the rules you want to use day to day.
DNS checks are a separate verification step. A changed exit IP doesn't mean every domain lookup is taking the expected route. When using a trusted DNS test, check whether the resolvers match your configuration. However, seeing a resolver located in a particular country doesn't by itself prove a leak; public DNS services may use distributed infrastructure.
Android Private DNS, a browser's built-in encrypted DNS, and the client's DNS settings can all affect the results. Don't turn them all off just to make a test page show a particular color. Check the client documentation first to see how it handles DNS, IPv6, and routing. If IPv6 traffic isn't being handled by the VPN, its exit may differ from what you expect. For work-related access, rely on the target app's actual requests and a configuration you can explain.
When the connection fails, narrow down the troubleshooting based on what you see
Routes are listed, but nothing can connect
Disconnect first and confirm that your regular internet connection works. Then check your account status and make sure the current configuration is enabled. Try another suitable route from the list for comparison; don't change the client and every setting at once. If only one route is affected, check the route list and client documentation before switching exits.
The browser works, but one app can't connect
Check the include and exclude lists for per-app routing, and make sure the target app isn't set to connect directly. Some apps keep existing connections open, so fully quit and reopen the app after changing rules. If only a specific feature is affected, also check its network requirements, account region, and service restrictions. A VPN connection doesn't grant eligibility to use a platform.
The connection drops when locking the screen or switching networks
First check whether the client is still running. If its process has stopped, review battery and background app settings. If the process is running but the node is disconnected, check reconnection settings and network error logs. If this happens only on a particular Wi-Fi network, that network's access policies may be involved. Don't assume every background connection issue is caused by battery settings.
Contact customer support
Use the support page to share your OS and client versions, network type, route name, error message, and what you did just before the issue occurred. You can include redacted logs, but remove subscription URLs, credentials, and full configurations. For general steps, see the troubleshooting guide, and avoid exposing account information in public channels.
You're done when the target app connects as expected. A complete check means the subscription updates, VPN permission is granted, background settings have been reviewed, and the exit and routing behavior make sense. Repeat these checks after changing clients or updating a configuration instead of relying only on the status bar icon.
