Samsung’s latest patents reveal three-way foldable device and its software

Last year we got our first real look at the Samsung Galaxy X or Flex, a foldable smartphone that comes with a folding screen which flattens out to function as a tablet-sized 2-in-1 device. The device uses Infinity Flex Display and new materials to make it functional.

Today, we discovered a series of patents that were published yesterday and the patent details foldable devices with various different characteristics. The design, however, remains same in the drawings.
