US tells consumers to stop using fire-prone Samsung phones

Following reports that the phones’ batteries have combusted during charging and normal use, the US Consumer Product Safety Commission said it was working on an official recall of the devices and that users should turn them off in the meantime. Samsung Electronics Co Ltd said it was working with the agency and asked customers to immediately turn in their Note 7 phones. It voluntarily issued a recall last week for 10 markets, including South Korea and the United States, and it said it was expediting shipments of replacement phones to customers in the United States. The US government action heralds more fallout for the South Korean manufacturer, which may take a financial hit from the recall and lose customers who are concerned about the quality of its flagship phones. Some analysts say the recall could cost Samsung nearly $5bn in revenue, after accounting for expenses from the recall process. For Samsung, which prides itself on manufacturing prowess, the scale of the recall is expected to be unprecedented. Some 2.5 million of the premium devices have been sold worldwide, the company has said. Its shares closed down 3.9% on Friday.
