The unprecedented move comes one day after Samsung halted production of the dangerously glitchy devices.
In a corporate statement, Samsung said it will also “ask all carrier and retail partners globally to stop sales and exchanges of the Galaxy Note 7” while it investigates the cause of the fires.
It also said, “Consumers with either an original Galaxy Note 7 or replacement Galaxy Note 7 device should power down and stop using the device.”

It’s a major setback for the South Korean electronics manufacturer. The company’s stock plunged more than 5% Tuesday morning in Seoul.
Samsung (SSNLF) released the 5.7-inch Galaxy Note 7 device in August in anticipation of Apple’s new iPhone 7. But customers immediately started complaining that their phones were catching fire.
