The iPhone 4s in 2012 was the first model to be manufactured simultaneously by two stand-alone companies: Foxconn and Pegatron, the latter also based in Taiwan. Although Foxconn still produces more iPhones, Pegatron's orders have been slowly increased: the company made part of the iPhone 5C line in 2013, and 30% of iPhone 6 devices in 2014. The 6 Plus model was produced solely by Foxconn.[54] In 2019, Apple investigated reports that some Foxconn managers had used rejected parts to build iPhones.[55] In India, Apple pays Wistron, a Taiwan-based manufacturer with a plant near Bangalore, to assemble iPhones to sell in the region.[56]
