The Galaxy SIII also scooped the Smartphone of the Year award at last night's O2 Guru TV-sponsored award ceremony at the London Film Museum in Covent Garden.
Google, Sony, Philips and Sky were also among the winners of the 20 categories that seek to award the best technology from the preceding 12 months.
Will Findlater, editor at Stuff magazine, said: "2012 has been a landmark year for technology, particularly in the tablet and smartphone spaces.
"While Apple's gadgets have been exemplary, its competitors have made even greater strides – and the Galaxy S III, with its 4.8in HD screen and unique interface innovations, shows that Samsung has made the greatest strides of all."
Despite being nominated for six awards, Apple won only the Computer of the Year category for its MacBook Pro with retina display.
