Samsung has opened up about the measures it took in order to maintain secrecy in the run up to the launch of the Galaxy S III. The project was so top secret that engineer Buyong-Joon Lee even flatly denied what he was doing to his 11-year-old son. Inside the labs, handsets were moved between facilities in locked boxes, while the prototypes were personally delivered by a globetrotting executive to network partners. The company went as far as producing three entirely different models, each one constructed as if it was the final product, so the team had to build and rebuild components to accommodate each design. Spare a thought for the procurement department, which had to rely on written descriptions of the handset in order to set the price and buy components -- enabling that May 3rd launch to go off with its surprises intact.
