Struggling Sony warned it needs to carry out years of root and branch reform before it can turn around its battered smartphone arm. The Japanese consumer giant, fresh from revealing a 172b yen ($1.5b) operating loss in the mobile communication segment for the latest quarter, said painful changes lay ahead, AFP reported. “We must carry out structural reform before we can launch a new business,” said Hiroki Totoki, new head of Sony Mobile Communications Inc and a Sony group executive. “Devices with communication functions have the potential to develop further,” he told market analysts and reporters in Tokyo.
