Samsung GALAXY S III

 

Throughout the eighteen-month design phase, Samsung implemented stringent security measures and design procedures to maintain secrecy of the eventual design until its launch. Designers worked on three prototypes concurrently while treating each of them as the final product. This required the duplication of effort as they had to "repeat the same process for all three types."[21][22] The prototypes, photos of which were forbidden, were locked in a separate lab accessible only by core designers, and the task of transporting them was performed by the company's employees.[23][22] Despite such security measures, specifications of one of the three units were leaked, although it differs from the eventual design.[24]
