With Android VPNs, the tricky part often comes after installation: importing a subscription, granting system permissions, and setting up traffic routing. This guide walks through the whole process, from installing a client to confirming it works. Load the configuration first, then check your exit IP and apps, and finally troubleshoot disconnections when the screen is off.
Before You Install: Understand Clients and Subscriptions
A client is the software that connects you to a service. A subscription provides the configuration details, often including server information and routing rules. Installing a client doesn’t guarantee you have access to a working route, and having a subscription URL doesn’t mean every client can read it. Check the service’s Android instructions before choosing an app.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are proxy protocols, not installation steps or plan tiers. Client support depends on its core, version, and configuration format. Even if an app supports a protocol, it may not be able to read every subscription format. If an import fails, check compatibility before trying different servers.
The VPNGlass Android client is available from the user dashboard. Sign in to download it; connection settings depend on your account status and the dashboard instructions. You can start at the client download page. Don’t assume that an app with the same name in search results is an official download.
Treat your subscription link like an account credential. It may contain an access token, so avoid sharing the full URL in screenshots, support requests, or public clipboards. If it has been exposed, check whether the dashboard lets you reset it, and contact support if needed.
Install the Client and Grant System Access
After downloading the installer from the dashboard, open it from your file manager or download history. Android may ask you to allow your browser or file manager to “install unknown apps.” Grant this permission only to the source you’re using, and consider turning it off again once installation is complete. If Android reports a damaged package, mismatched signature, or incompatible device, return to the download page and check the file. Don’t bypass the warning.
- Open the client, check the app name, and read the first-run instructions. Don’t import test configurations from unknown sources.
- Import a subscription or sign in as directed by the service. Make sure servers appear in the app instead of an empty configuration.
- When you tap Connect, read Android’s VPN connection request. Allow it only after confirming it came from the client you just installed.
- Check the connection status in the client and look for the VPN indicator in the system status bar or network settings. A persistent notification may also appear.
Many proxy clients use Android’s VpnService to route device traffic, which triggers a system VPN permission request. This doesn’t give the app every system permission, nor does it mean all device traffic will necessarily use a remote route. The actual traffic scope depends on routing rules, excluded apps, and tunnel settings.
Android generally allows only one VPN service to run at a time for the same user or profile. If you already use another VPN, an ad blocker that uses local VPN mode, or a packet-capture app, a new connection may replace the existing one. If permission prompts keep reappearing or the connection stops immediately, check for these conflicts instead of running several tools at once.
Import a Subscription: Check the Format, Then Update
Copy the subscription link for your client from the dashboard, then look in the app for options such as “Configuration,” “Subscription,” or “Import from URL.” Menu names vary, but the process is much the same: paste the full URL, save it, update the configuration, and then enable it. Saving the URL without updating it usually won’t add any servers.
Before importing, check that the URL hasn’t picked up spaces, line breaks, or punctuation from a chat app. If the app says the format isn’t supported, return to the dashboard and find the link for that client. Don’t paste a private subscription into a third-party online converter: it could expose the full URL and server credentials.
| Symptom | Check first | What to do |
|---|---|---|
| Can’t save the URL | Is the copied text complete, and did you choose the right import option? | Copy the link again from the dashboard and use URL import rather than local file import. |
| Format error when updating | Is the subscription format compatible with the client’s core? | Choose the right link based on the instructions; don’t guess the format from the protocol name. |
| Update succeeds, but no servers appear | Account status, active configuration, and server filters | Check your status in the dashboard, enable the updated configuration, and review the filters. |
| Subscription update times out | Is your local network working, and is an existing proxy interfering with the request? | Check that regular websites load, then adjust the update method as described in the client’s instructions. |
A successful subscription update means the client retrieved and parsed the configuration, not that every server can connect. Next, select a server and test the app you need to use. If server details have just changed in the dashboard, update the configuration manually and try again. Repeatedly tapping Update won’t fix a local network issue.
Servers and Routing: Start with the Default Rules
For your first setup, keep the service’s default routing mode. Rule-based routing uses conditions such as domains, addresses, or apps to decide whether traffic connects directly or through a proxy. Global mode usually sends more traffic through the selected proxy, but the exact scope depends on the client, bypass settings, and excluded apps. Don’t assume that choosing Global verifies that all traffic is routed through the proxy.
If just one app won’t connect, check whether it’s excluded from the VPN, then review which rule matches its domain. In some clients, the per-app list means “proxy only these apps”; in others, it means “don’t proxy these apps”—the opposite. Read the setting carefully and reconnect as the client requires after making changes.
Labels such as direct, relay, and IEPL describe how a route is arranged, not whether an app will work. Direct usually means the device connects straight to an overseas server; relay routes traffic through an intermediary; IEPL usually refers to a link carried over a dedicated Ethernet line. A label alone can’t tell you how a connection will perform. Test the apps you need under your network conditions and at the times you plan to use them.
Choosing a server as a beginner: Pick a region supported by the service you want to access, keep the default routing rules, and confirm your everyday apps work before fine-tuning anything. Changing the server, DNS, and rules all at once makes it hard to tell which setting helped.
Battery Settings: Prevent Disconnections When the Screen Is Off
Android and device manufacturers’ battery management features can restrict apps in the background. A common sign is that the connection works with the screen on but stops after you lock the device or switch apps, then recovers when you reopen the client. Check whether the VPN indicator has disappeared too: a system-terminated tunnel is a different problem from an active tunnel with an unreachable remote server.
Open the client’s app details in system settings and check its battery or background activity options. Follow your device’s instructions to allow background activity and turn off battery optimization for that app. Some devices also have settings for auto-start or background protection; names vary, so don’t look for an exact match. Change settings only for the apps that need them—don’t disable battery restrictions for every app.
- ✅ Allow the client to run in the background, and check whether the system restricts its background network access.
- ✅ If Data Saver is on, check whether the client needs permission to use background data.
- ✅ Reopen the app you need after locking the screen, then check that the client and system show the same VPN status.
- ❌ Don’t repeatedly swipe the client away from recent apps, and don’t dismiss its persistent notification as irrelevant.
Android’s “Always-on VPN” and “Block connections without VPN” are optional settings, not steps every beginner needs to take. The latter can block network access when the client isn’t connected, and may affect rule-based routing. First verify a regular connection, then decide whether to enable these options based on client support and your needs.
Verify the Connection: Check Your Exit IP, DNS, and Apps
“Connected” only means the client reports a connection. For a better check, compare the system status, your exit IP, and the results in the apps you need. Note your public IP and approximate region while disconnected, then connect and refresh an IP lookup page that you know is routed through the proxy. If the lookup site is set to connect directly, seeing your local exit IP doesn’t by itself mean the VPN has failed.
Once the exit region looks right, open the apps you actually need. If a browser works but an app doesn’t, check per-app exclusions, the app’s cache, your account region, and the platform’s own restrictions. A connection won’t change your account details or guarantee that a platform accepts your current exit IP. Don’t assume every app is covered just because a webpage loads.
DNS Checks: Look Beyond the Region Label
A DNS leak generally means that lookup requests expected to follow a particular route are instead sent to an unexpected resolver or network. If a test shows your local ISP’s resolver, it’s worth investigating further. But resolver location labels, shared exits, and forwarding can affect the results, so don’t draw conclusions from the country name alone.
Android Private DNS, a browser’s Secure DNS, and the client’s DNS settings may all affect how names are resolved. Private DNS affects the system’s DNS path, but whether it bypasses the tunnel depends on how the client routes traffic. A browser may also use encrypted DNS on its own. Record your original settings, then adjust them one at a time using the client’s documentation and retest after each change. Turning off encrypted DNS isn’t a universal fix.
Don’t sign in to unfamiliar test sites or submit your subscription URL when checking your connection. Exit IP and DNS tests serve different purposes, and no single result proves that every app is routed as expected—or that your activity is anonymous.
When Something Goes Wrong, Troubleshoot by Symptom
If nothing can connect, disconnect the client first and check your local network. Hotel and public Wi-Fi may require you to complete a network sign-in first. If “Block connections without VPN” is enabled, understand how it works before troubleshooting. If switching between Wi-Fi and mobile data changes the result, the network you’re connecting through may be the cause; it doesn’t necessarily mean your subscription has expired.
If the client connects but an app won’t load, keep the current configuration and try a server in a region supported by that service. If only one app fails, check its routing rules and account region. If the problem starts only when the screen is off, focus on background restrictions. Following the symptoms makes it easier to find useful clues than repeatedly uninstalling and reinstalling the app.
When asking for help, include your device and operating system, client version, time of the error, network type, error message, and steps you’ve already tried. Hide subscription links, account credentials, and personal information in screenshots. For more setup steps, see the setup guide; for symptom-based help, see troubleshooting.
Once your setup is stable, choose a data plan that fits your usage. VPNGlass monthly subscription data resets monthly on the activation date. Data add-ons remain available until used and never expire. Unlimited devices doesn’t mean unlimited data, so keep an eye on your plan’s remaining allowance when using multiple devices. Check prices and terms on the plans page; there’s no need to upgrade just to troubleshoot a connection.
