Smartisan Pro 2S is the revised edition of the mid-range Smartisan Pro lineup. In this revision Smartisan experimented with a whole new CMF, combining a glossy anodized aluminum mid-frame and a glass back cover coated with shiny film. They have also further polished various design details, such as a reduction of an already-thin profile (to only 7.15mm), a more-comfortable-to-hold streamlined outline, and better polished color editions (shiny blue and shiny red) to better match our targeted consumers.
