The drumbeats are getting louder and all of the previous patent applications are telling us that Apple is indeed working on a foldable iPhone.

One of the prototypes reportedly resembled the Samsung Galaxy Fold with a folding mechanism that is similar to opening and closing a book. This device turns a smartphone into a tablet when opened.
