Following a massive retail and advertising push, Samsung’s flagship Galaxy S III handset overtook Apple’s iPhone 4S as the world’s best-selling smartphone in the third quarter of this year, according to a Strategy Analytics survey. The Samsung phone sold an estimated 1.8 million units more than the iPhone 4S. Samsung’s lead will be short-lived as Strategy Analytics estimates that the iPhone 5 will become the world’s #1 smartphone in Q4.
