yes, that's the reality now because Android has better security than computers that need to do their own security and the type of application used will be more varied because computers can do custom and things like that.
Microsoft Windows has crap glued on it that was written in 2001. The NSA is deeply embedded into it and so many bugs go unfixed. That's why there's a ton of malware for it. And yet it is still marketed by dozens of brands as the modern thing. It infuriates me to the point where I wish I could just write all the software needed to make Linux a truly viable Windows competitor. Sure, I could get a Mac, but I haven't found any vendors selling them around here yet.
As for Android, consider using Samsung Knox to store all your crypto applications. It's very effective.
