this could be used in linux phones as well I suppose (waydroid requires linux-zen which just adds friction imo)
Though I like waydroid very much , I also really like this idea of having android apps as flatpak applications which I can install rather easily without having to configure to install a custom kernel and do 10 more different things (like maybe adding play store if app is not available) (a arm implementation if app isn't working)
lets hope that it works better than that and gives a plug n play experience
