Samsung isn’t the only supplier that Apple is trying to rely less upon these days. Unnamed sources tell The Wall Street Journal that Apple is expanding its roster of manufacturers so that it won’t have to depend so heavily on Foxconn parent company Hon Hai going forward. The Journal’s sources say that a combination of factors, including public relations headaches caused by Foxconn’s controversial labor practices and poor yields of the iPhone 5 last year, have led to rising tensions between the two companies. To ease its reliance on Foxconn, Apple will turn to Taiwanese manufacturer Wistron to help with iPhone 5c production and to Compal Communications to help with iPad mini production.
