Samsung's next dual camera phones are the anti-Note 8

Both much more affordable, much more basic Android phones, the presence of two lenses on the back is basically the only thing the Galaxy J7+ and Galaxy C8 have in common with their top-notch sibling. There's Android, but no integrated S Pen stylus; there's a fingerprint reader, but no Bixby Voice software.
It seems that for Samsung, the dual camera floodgates are open, with or without premium features.
