Valve’s SteamOS 3.8.25 beta adds initial or updated controller support for several third-party handhelds, including devices from MSI, Ayaneo, Konkr and OneXPlayer. 4 Reviews ← exclude selected types ← exclude selected tagsValve continues to broaden SteamOS compatibility beyond its own Steam Deck hardware, with the latest 3.8.25 beta adding initial gamepad support for several third-party handhelds. These include the MSI Claw 8 EX AI+, the Ayaneo Pocket S2 and Konkr Fit, while the OneXPlayer Apex receives updated controller support. But the company still remains cautious in its approach, incrementally adding support instead of declaring every third-party device fully compatible. Altogether, the update signals Valve's ongoing effort to make SteamOS a viable, more universal option across the fast-growing handheld gaming PC market.
