Because of overwhelming demand and a manufacturing problem with the blue variant of the phone, there was an extensive shortage of the S III, especially in the United States. Nevertheless, the S III was well-received commercially and critically, with some technology commentators touting it as the "iPhone killer". In September 2012, TechRadar ranked it as the No. 1 handset in its constantly updated list of the 20 best mobile phones, while Stuff magazine likewise ranked it at No. 1 in its list of 10 best smartphones in May 2012. The handset also won the "European Mobile Phone of 2012–13" award from the European Imaging and Sound Association, as well as T3 magazine's "Phone of the Year" award for 2012. It played a major role in boosting Samsung's record operating profit during the second quarter of 2012. As of November 2012[update], the S III is part of a high-profile lawsuit between Samsung and Apple. In November 2012, research firm Strategy Analytics announced that the S III had overtaken Apple's iPhone 4S to become the world's best-selling smartphone model in Q3 2012.
