Reports on the meteoric rise of smartphones are beginning to sound like broken records, but there aren't any signs of that growth stopping anytime soon. Case in point: Gartner's latest stats show that smartphones sales jumped 20 percent to reach 301 million units in the third quarter. And yes, that jump came at the expense of feature phones sales, which fell by 25 percent. No surprises there, but the smartphone growth did lead to some intriguing movement among the top five smartphone vendors. Xiaomi joined the prestigious group for the first time, kicking out LG in the process. Samsung is still king of the hill, but its smartphone sales fell another eight percentage points in the quarter, leaving it with just 24.4 percent of the market.
