Sony cameras run Linux and contain an Android subsystem (mostly 2.x AFAIK). A "cold boot" takes a bit longer (3-4 seconds), the main UI and camera functions are implemented natively as far as I can tell and Android is only used for apps. It's possible to write homebrew apps [1], but there's currently no way to access the proprietary image processor, so there's not too much you can actually do. I don't think they'll open up the platform, unfortunately. [1] https://github.com/ma1co/OpenMemories-Framework https://github.com/ma1co/OpenMemories-Framework
