While many tech companies (Apple being a notable example) pride themselves on their secrecy, Samsung may be the first to explain exactly how it kept the launch of a new flagship device quiet. Those working on the Galaxy S III weren’t able to tell their families what they were working on, nor were photos or drawings of the new device allowed. The secrecy extended into Samsung itself, with only one small team of engineers allowed to view the device before its launch.
