Key points in a minute
- Install the client from an official app store or the developer’s repository.
- A subscription link is more convenient than entering settings by hand, and it should be kept as safe as a password.
- For sensitive use, check the Always-on VPN and Block connections without VPN settings.
- Excluding the app from battery optimization helps if the connection drops unexpectedly.
Choosing an app
Android supports system VPN profiles, but VLESS and Xray-based subscriptions need a compatible client. Your provider usually recommends a specific app. Check the developer name, the number of downloads, the date of the last update, and the link to the official project.
Don’t install an APK from some random channel if the same version is available in a trusted store or on the official releases page. A VPN app gets access to all of your device’s network traffic, so where the build comes from is critical.
Importing a profile or subscription
Open your provider’s account dashboard on the same phone and use the import button. If the app offers QR code scanning, it’s easier to display the code on another trusted device. After import, the profile should appear in the server list.
Don’t send a screenshot of the QR code in a chat or save it to a public cloud. The QR code and the link usually contain the secret that grants access. If someone else got hold of them, delete the key in your dashboard and generate a new one.
Android’s system permission
The first time you connect, Android shows a standard request to set up a VPN connection. A key or VPN icon in the status bar means the interface is active. The permission itself doesn’t vouch for the quality of the service — it only allows the app to handle traffic.
For constant protection, open your network settings and find Always-on VPN. The extra option “Block connections without VPN” keeps traffic from going out directly if the connection drops, but it may leave the device offline for a while until the app recovers.
Auto-start and battery use
Some Android skins aggressively stop background apps. If the connection disappears after you lock the screen, allow the client to run in the background and exclude it from battery optimization. The names of these settings vary by manufacturer.
Keeping a VPN on all the time uses battery because it maintains a network interface and encrypts traffic. Unusually high drain is often caused by an unstable network, frequent reconnects, or an app that actively sends data in the background.
Checking the connection
Open an IP check page and make sure your external address has changed to one in the location you selected. Then test regular websites, your messenger, a call, and switching from Wi‑Fi to mobile data. What matters isn’t a single speed test number but whether your everyday tasks work.
If some apps won’t open, temporarily turn off split tunneling, custom DNS, and blockers. Turn the settings back on one at a time — that makes it easier to find the conflict.
If your VPN won’t connect on Android
Sync the date and time, restart the client, update the subscription, and try a different network. Check whether a second VPN, a local firewall, or a parental control app is active. Android allows only one main VPN interface at a time.
Before contacting support, write down your phone model, Android version, the client’s name and version, the network type, and the exact error text. Don’t attach your full configuration or subscription link — an anonymized log is all a support specialist needs.
FAQ
FAQ
Which VPN client do I need for VLESS on Android?
You need a client that supports Xray/VLESS and the specific parameters of your profile. Use the app your provider recommends and download it from an official source.
Why does Android turn off my VPN in the background?
Most often, the manufacturer’s power-saving mode is restricting the app. Allow it to run in the background and check the Always-on VPN setting.
Can I use two VPNs at the same time?
Android usually allows one system VPN interface. Some apps can chain connections internally, but two separate VPN clients tend to conflict.
