After 35 reported incidents of overheating smartphones worldwide, Samsung made the unprecedented decision to recall every single one of the Galaxy Note 7 smartphones sold. That's said to be 1 million of the 2.5 million that were manufactured. (Since the recall was first announced, the number of explosive Note 7s has nearly quadrupled.) The company says it's stopped all sales and shipments of the Note 7 and is working with government agencies and cellular carriers around the world to provide refunds and exchanges for the phone.
