(FOX NEWS) - Samsung halted sales of the Galaxy Note 7 smartphone Friday after finding batteries of some of the devices exploded while they were charged.
Koh Dong-jin, president of Samsung's mobile business, said customers who already bought Note 7s will be able to swap them for new smartphones, regardless of when they purchased them. Note 7 sales launched just two weeks ago.
Samsung issued its first global recall of the flagship smartphone because it has not found ways to specify exactly which phones may endanger the user. The smartphones are being yanked from shelves in 10 countries, including the U.S. and South Korea.
Koh said the company's investigation found that a battery cell made by one of its two battery suppliers caused the phone to catch fire. He refused to name the battery supplier.
"There was a tiny problem in the manufacturing process so it was very difficult to find out," Koh told reporters at a news conference.
