As the biggest tech company to throw its hat into the ring, many were eager to learn about the Galaxy Fold at Samsung Unpacked and it didn't disappoint. When closed, the Fold has a secondary 4.6-inch display that serves as its "cover," with all the usual features you'd expect on a phone. When you're ready for something bigger, the Fold opens up like a book to a 7.3-inch tablet.
