The name Lepton appeared on Steam and SteamDB just a few weeks after Valve unveiled the Steam Frame headset, which will be able to run Android apps.
In our new interview with Valve’s Pierre-Loup Griffais, he mentioned the Frame uses “a similar compatibility layer as Proton, just targeted at Android.”

I guess that is a streamlined version of Waydroid?
No, Waydroid merely used other projects wrapped in some crappy Python scripts & had a multitude of issues. If it is anything like Waydroid then I’ll lose respect for Valve.
We know that it started as a fork of Waydroid
But:
After finishing to read the interview it does indeed sound different, but it is odd that this isn’t open-source somewhere like Proton and Fex always were.
