If you are interacting with Gamehub (proprietary), then I would look into Gamehub-lite (the patches are Open Source on top of the proprietary original): github.com/Producdevity/gamehub-lite

GameHub Lite is a modified version of GameHub that:

• Removes telemetry and tracking - Umeng analytics, Firebase, JPush, crash reporting
• Removes bloat - Cloud Streaming, Xbox Cloud Gaming, Social features, etc.
• Removes account requirement - Use the app without logging in
• Reduces app size - From 118MB to 52MB (-56%)
• Removes unnecessary permissions - Location, contacts, phone state, etc.
• Adds offline support - Works without constant network connectivity
• Changes package name - gamehub.lite for side-by-side installation
• Adds custom news page - Uses community API for updates

gamenative.app - And then there is GameNative, which is entirely Open Source. Some say that the GameHub devs stealing code or ideas from GameNative, because its suspicious whenever they have a new feature, it only takes very short amount of time for GameHub to do it too. But nobody knows. So I would personally recommend GameNative instead.

I personally didn’t experiment with ARM yet, outside Raspberry Pie 3B and that is ages ago (10 years…). And off course phones. The Steam Frame is really something else and more than just VR. I’m surprised it will have Android app support. Maybe Valve plans on adding an Android category that is not VR related? But I guess developers would need to release and upload their games to this shop, similar to how they do it on Google or F-Droid. This is highly speculative from my part BTW, there are no words about that. Valve tried to expand into films too, which would have been something like Amazon Prime videos or like that. BTW I would love to watch a film in VR.
