The patent drawings depict a phone with a rotating mechanism that allows the primary display to rotate 180 degrees, revealing the secondary display underneath. There’s another change to Samsung’s design: The main display also has a hinge that allows the phone to fold in half.
The patent also shows the camera module in the upper right corner, the charging port, microphone, and speakers at the bottom. Theoretically, this design would allow for the use of three folding devices for media writing.
