A known leaker and SteamVR data miner named Bradley Lynch reports that Valve is working on an Android emulator. Lynch has spotted five apps in a package on SteamDB, with two of them displaying new artwork that references Waydroid, an open-source and free Android emulator.
It’s just waydroid
I mean you could say the Steam Deck is “just KDE on Arch”.
The difference is how they implement it and what it’s used for. This could be huge for “apps” on the Steam Deck, for example. Or it could be a quirky experiment or feature nobody uses. Time will tell.
