The recovery in Samsung Electronics Co Ltd's (005930.KS) mobile business suffered a blow on Thursday as reports of exploding batteries forced the firm to delay shipments of Galaxy Note 7 smartphones, and knocked $7 billion off its market value.
Investors drove the stock to two-week lows after the global smartphone leader told Reuters late on Wednesday the shipments had been delayed for quality control testing, and that shipments to South Korea's top three mobile carriers had been halted.
