Another story with a hint of Star Trek in it, Samsung has filed a patent  for a smartphone with a that can be folded in half like a flip phone. The device would also have a secondary screen, that’s activated when it’s folded shut. There’s even a complex “semiautomatic” powered folding action as one of the options. As Engadget reports, “Of course, patents don’t usually lead directly to products…but it’s fun to see what a company’s engineers are dreaming about.”
