Older ZTE phone ($100) on earlier Android - I can install an SSH/rsync app and pull files down to my desktop easily. Newer cheap Samsung phone ($100 but lower quality) - can no longer install any such app due to new Android policy, and it has a cheap band of plastic holding the screen in - after 1 drop I had to use tape to keep the screen from flopping out of the "tray" it is nestled into.
