Phone (4b) is shaped by two key design elements from the Phone (4a) series: the Glyph Bar and the unibody design. Its final form was selected from more than 20 internal iterations, with visual simplicity, comfort, and durability being balanced. A crystal-clear soft polymer camera module is blended into an eco-polycarbonate body, finished with a three-layer coating. IP64 protection and resistance to 600N bending force are also included.
