Another idea for android phones is octo4a (octopi for android) if you’re into 3d printing. That’s what my nexus 6 with a dead display is doing. Also you can run docker on 'em if you can build the kernel, and it’s not too ancient (AFAIK, docker needs 3.something, so it’s like android 6 in general, maybe?), but I personally never got to it, unfortunately
Yeah, probably
