Valve's SteamOS is now accessible on Android handhelds through an app called DroidDeck, which allows users to engage with games in a familiar interface. The installation process involves disabling the “Child-process limit” in Developer Options and using Wireless ADB Debugging if necessary. Users can then access the Steam section of the app to download essential components like the FEX and Proton drivers. DroidDeck also features a “Desktop” tab for a Linux desktop environment and enables the installation of emulators within the SteamOS. The app is currently available for download on GitHub, and developers are actively working on enhancements and bug fixes.
