The PuzzlePhone was an uncompleted modular smartphone project by Circular Devices. The device's design was intended to allow its main parts, which would be specific modules, to be easily assembled and replaced by the user.

The phone's modular construction was intended to allow easy switching between Sailfish OS and Android mobile operating systems. In May 2017 the project was put on hold because of lack of funds. The company vanished in August 2020.

Construction

The main modules were intended to be:

• 1: Brain - The Brain would contain essential electronics: the CPU, GPU, RAM, memory, and cameras.
• 2: Spine - The Spine is the structure: the display. Core spine elements would be available in a variety of sizes and materials.
• 3: Heart - The Heart contains the battery: the enabler of secondary electronics and features chosen by the user.
