Valve has long been preparing its software stack for the arrival of both the Steam Machine and the upcoming Steam Frame, and the latest update sees the gaming giant add a long list of fixes, QoL improvements, and features to SteamVR as well as changes to the developer back-end in order to prepare for the Steam Frame. As pointed out by u/FantasySynthDev on r/Steam on Reddit, Valve's developer back-end now includes the option to select Android as a supported operating system—a change that delivers on Valve's promise to increase Android support for the Frame at GDC.
The new toggle seems to be there to indicate to users that there is an Android version of the game available, but the Redditor notes that checking the box and uploading an Android build does not yet make an Android version available for download in Steam, further suggesting that this is more preparation for the Steam Frame. Steam has also added documentation for the Android APK upload and VR testing workflows in the Steamworks documentation. While the Steam Frame and Steam Machine may not launch as early as many gamers had hoped, these changes to the back-end and documentation suggest that the new hardware may not launch as long after the "first half of 2026" plans as many feared when Valve declined to announce pricing earlier this year.
