VirtualGamePad lets you use your Android phone as a gamepad for your Windows PC.
It's similar to DroidJoy, but free and open source.

VirtualGamePad running on an Android 12 device:

VirtualGamePad Server running on Windows 11:

To use VirtualGamePad, you need to install the Android app (client) on your phone and the Windows app (server) on your PC.

Grab the latest APK from the releases page and install it on your phone.

Grab the latest archive(.zip) from the releases page, extract it and run VGamepadPC.exe.

Run the server on your PC and the client on your phone.
Connect to the server from the Android app by entering the IP address and port of the server.
Both devices need to be on the same network.

There's an FAQ for gamers.

If you're having trouble connecting to the server, try disabling your firewall or adding an exception for the server.
On Windows, you will be prompted to allow the server to communicate through the firewall when you run it for the first time.

If you're still having trouble, start a hotspot on your phone and connect your PC to it.
Then, restart the server and try connecting again.

The built-in QR code scanner might stop working after a while. This is a known issue and caused by a bug in the Google library used for scanning. Clear the data for Google Play Services to fix it. Or use a third-party QR code scanner.

If it is a newer title with built-in support for Gamepads on PC, you might face some problems.
Try running the server as admin. 🛡️

The game should not be running as admin. This prevents input injection.

Games without gamepad support should work out of the box.
