The following year, Samsung launched the S4 Zoom on the basis of the Galaxy S4, which combines the functions of a smartphone and a camera, focusing on photography capabilities while making up for the Galaxy Camera's "can't make calls" bug, which not only meets the needs of daily communication and entertainment, but also provides a photo experience close to that of a professional camera.

At the same time, K Zoom also supports more shooting modes and creative filters, as well as 1080p Full HD video recording at 60fps.

This design allows one main camera to function as both wide-angle and portrait lenses, while the telescopic design helps to optimize the interior space of the body. In addition, the lens can also support waterproof and drop auto-retraction protection when ejected, providing both ease of use and durability.
