V2flyNG is an Android client for connecting to V2Ray-compatible proxy profiles. If the application is not distributed through Google Play in your region, you can still install it from the official download page by obtaining the correct APK package. The important parts are choosing a package that matches your phone, allowing installation from the browser or file manager, importing a subscription carefully, and confirming that Android has created the VPN connection successfully.
This beginner-friendly guide explains how to download V2flyNG from the V2Ray for Windows website, select the correct Android APK, enable the temporary Android permission required for installation, import a subscription or profile, and test the connection. It also covers package compatibility, VpnService authorization, battery restrictions, subscription update failures, and the safest way to remove the APK installation permission after setup.
Before You Download
Before downloading V2flyNG, check the Android version, available storage, and source of the APK. The application itself is usually small, but Android may need additional temporary space while verifying and installing the package. Keeping at least 100 MB of free storage avoids installation failures caused by a full system partition. You should also use a stable Wi-Fi or mobile connection because an interrupted download may produce an incomplete APK.
Open the site’s download page and choose the Android section. Do not rename an APK before installing it, and do not open several packages at random simply because their filenames look similar. A package intended for a different CPU architecture may fail with an “app not installed” message, while a split package or archive may not be directly installable by the default Android package installer.
The safest download path is to visit Download from this site, select Android, and use the V2flyNG entry. The download page is preferable to unknown file-sharing pages because APK files can be modified, repackaged, or bundled with unwanted software. If Android displays a warning about installing an application from an unknown source, read the prompt carefully and confirm that the file is the V2flyNG package you intentionally downloaded.
Use the package name, not only the filename
A filename can be copied or changed, but Android shows the application name and package information during installation. If the installer identifies a different application, requests unrelated permissions, or redirects you to another download, cancel the process and download V2flyNG again from the official site.
Choose the Right APK
Most recent Android phones use a 64-bit ARM processor, commonly represented as arm64-v8a. Older phones may use 32-bit ARM, represented as armeabi-v7a. Some Android devices based on Intel processors use x86 or x86_64, although these are much less common in current phones. If the download page provides a universal APK, it is normally the simplest choice because it includes support for more than one architecture, but it may be larger than an architecture-specific package.
Check your phone’s specifications in “Settings” → “About phone” before selecting a specialized package. Some Android versions show “64-bit” in the system information, while others require a device information utility to display the ABI. If you are unsure, use the universal V2flyNG APK when one is provided. Do not install both a universal package and an architecture-specific package at the same time merely to test them; Android may treat them as the same application and create a signature or downgrade conflict.
Supports a broad range of Android CPU architectures and is the easiest option when you cannot confirm the device ABI. The file may be larger, but installation is usually straightforward.
Designed for modern 64-bit ARM phones. It is often smaller and can be a good choice when the device specification clearly reports arm64-v8a.
Designed for older 32-bit ARM devices. An ARM64-only package generally cannot be installed on a 32-bit system.
There is another distinction between an APK and an archive. An APK can normally be opened directly by Android’s package installer. A ZIP archive must first be extracted, and the extracted contents may include several packages or configuration files that are not intended to be installed individually. If the download ends with an extension other than .apk, check the download page instructions before opening it.
Install the V2flyNG APK
Android blocks installation from a browser or file manager until you grant that specific application permission to install unknown applications. This permission is separate from the VPN permission requested later. Allowing the browser to install one APK does not automatically give V2flyNG permission to access your traffic, and allowing V2flyNG to create a VPN does not allow it to install other applications.
Open the download page
Go to the site’s Download page, choose Android, and select the V2flyNG APK that matches your device. Wait until the browser reports that the download is complete.
Open the downloaded file
Open the notification shade and tap the completed download, or go to “Files” → “Downloads” and tap the V2flyNG file. Android should open the package installer.
Allow this source
If Android blocks the installation, tap “Settings” on the warning screen and enable “Allow from this source” for the browser or file manager that opened the APK. Return to the installer and continue.
Confirm installation
Review the application name, tap “Install”, and wait for Android to finish. When the installer reports success, tap “Open” or find V2flyNG in the application list.
Disable the source permission
After installation, return to “Settings” → “Apps” → “Special app access” → “Install unknown apps”, select the browser or file manager, and turn off “Allow from this source” if you do not need it again.
The exact labels vary between Android versions and manufacturer interfaces. On some devices, the path is “Settings” → “Security and privacy” → “More security settings” → “Install unknown apps”. The setting you need is always associated with the application that opened the APK, not necessarily with V2flyNG itself. If you downloaded the file in a browser but opened it from a file manager, Android may ask you to authorize the file manager instead.
Do not disable Android security globally
You do not need to turn off all security checks or enable developer options to install a normal APK. Grant the installation permission only to the browser or file manager being used, complete the installation, and then revoke that permission. If Android reports that the package is corrupt, incompatible, or conflicts with an existing signature, download the correct package again instead of weakening system security.
Import a Subscription or Profile
Installing the application does not provide a working proxy profile. V2flyNG needs at least one valid server configuration, such as a subscription URL supplied by your service provider or a manually exported profile. Keep the subscription URL private: anyone who obtains it may be able to retrieve the server list associated with that link. Do not paste it into public chats, screenshots, or online diagnostic tools.
Open V2flyNG and look for the profile or server management screen. Depending on the application build, the action may be labeled “Subscriptions”, “Import config”, “Add”, or “+”. For a subscription, paste the complete HTTPS URL, give it a recognizable name, save it, and use “Update” or “Update all” to retrieve the profiles. If your provider gives you a QR code or a single share link, use the corresponding scan or import option instead of treating it as a subscription URL.
- Use the complete link, including its query string if one is present.
- Do not add spaces or quotation marks around the URL.
- Update the subscription while the phone has ordinary internet access; the proxy cannot update itself if no route is available.
- Select one imported node before tapping the connect button.
- Keep an offline exported profile only if your provider allows it and the profile does not expose credentials unnecessarily.
A subscription update can fail even when the APK installation was successful. A timeout usually means the phone cannot reach the subscription host, the URL has expired, or the server is temporarily unavailable. A successful update with an empty list may indicate an expired account, a provider-side filtering rule, or an incorrectly copied URL. If the provider supplies an update interval or user-agent requirement, follow that provider’s instructions rather than repeatedly pressing the update button.
One URL can provide multiple nodes and makes it easier to refresh server information when the provider changes an address or port.
A single share link, QR code, or exported profile is quick to add and is useful when you only need one server. It may require manual replacement if the server changes.
Connect and Verify the VPN
After importing a profile, select a node and tap the main connect button. Android will display a VpnService authorization dialog the first time an application requests a VPN connection. Read the dialog and tap “OK” or “Allow” to let V2flyNG create the local VPN interface. This is a normal Android system permission, not a request to install another package.
When the connection succeeds, Android normally shows a VPN key or VPN status indicator in the status bar. V2flyNG should also change its connection state and display traffic counters or connection information. Open a browser and load a reliable website, then compare the result with the client’s connection log. A successful connection requires more than a visible VPN icon: the selected node must respond, the profile must be valid, and routing rules must send the test traffic through the intended outbound.
Select a node
Open the V2flyNG profile list, choose an imported node with a valid address, port, user identity, and transport settings, and make it the active selection.
Start the VPN
Tap the connect button. When Android displays the VpnService prompt, tap “OK” or “Allow” to authorize the virtual network interface.
Check the status icon
Confirm that Android shows a VPN indicator and that V2flyNG reports a connected state. If the status changes back immediately, open the client log for the first error line.
Test ordinary traffic
Open a browser and visit a normal website. If the page loads slowly or not at all, test another node rather than changing several settings at once.
Only one VPN service can normally be active at a time. If another security, filtering, or tunneling application is already connected, V2flyNG may fail to start or may replace the existing VPN. Disconnect the other service before testing V2flyNG. Also check whether Android’s data saver, private DNS configuration, or a restricted network is preventing the selected node from completing its handshake.
A VPN icon is a starting signal, not a speed test
The VPN indicator confirms that Android granted VpnService access and that a virtual interface exists. It does not prove that the remote node is reachable or that every application is using the proxy. Confirm the node log, load a website, and test a second node if the first connection has no usable traffic.
Fix Common Installation Problems
Most setup failures can be separated into three stages: downloading the file, installing the package, and connecting to a profile. Troubleshooting becomes easier when you identify the stage first. An “unknown source” warning belongs to Android’s installation permission. An “app not installed” warning often points to an incompatible architecture, a damaged download, insufficient storage, or a signature conflict. A connected VPN with no traffic is usually a profile, routing, DNS, or remote-server problem rather than an APK problem.
Why does Android say “App not installed”?
First check that at least 100 MB of storage is available. Then download the APK again, confirm that it matches your Android CPU architecture, and remove an older conflicting V2flyNG installation only if you have safely backed up profiles. Installing a different package signed by another source can cause a signature conflict.
Why can’t the browser install the APK?
Go to “Settings” → “Apps” → “Special app access” → “Install unknown apps”, select the browser used for the download, and enable “Allow from this source”. Return to the completed download and open it again. If a file manager opened the APK, authorize that file manager instead.
Why is the subscription list empty?
Check the URL for missing characters or spaces, confirm that the phone has internet access, and run the update again. If the request times out, use the provider’s current subscription link or contact the provider. A successful APK installation does not guarantee that the subscription server is available.
Why does V2flyNG disconnect in the background?
Go to “Settings” → “Apps” → “V2flyNG” → “Battery” and choose “Unrestricted” or “Allow background activity”. On some devices, also enable auto-start and lock V2flyNG in the recent-apps screen. These labels vary by manufacturer, but the goal is to prevent Android from suspending the VPN service.
If installation still fails after choosing the correct package, delete the incomplete download and start again from the official download page. If the application opens but a node will not connect, select another profile, inspect the client log, and confirm that the subscription has not expired.

Keep the source-install permission disabled after setup, protect your subscription URL, and update V2flyNG only from a source you trust.
