Virtual Master – virtual Android on your Android phone

Virtual Master is an app that creates a sandboxed Android system inside your current Android OS, functioning like a virtual phone. This allows you to install and run apps independently from your main system. It offers near-native performance and supports guest systems from Android 4 up to Android 11, with Android 7 being the most stable.

However, there are some limitations:

- The virtual Android version cannot be higher than your host system (e.g., if your phone runs Android 10, you can't use Android 11 inside the VM).

- Requires at least 2GB of RAM (6GB+ recommended) and 8GB of free storage (plus space for any apps you install in the VM).

- It's not open-source and uses a freemium model.

While there is a community around it, it's relatively inactive (~5 messages/day), so support and troubleshooting help may be limited.

any open source alternatives?
