Samsung issued an alert to customers on Monday, asking users to immediately turn off their Galaxy Note 7 smartphones -- which have been spontaneously catching fire.
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 Note7" while it investigates the cause of the fires.
It also said, "Consumers with either an original Galaxy Note7 or replacement Galaxy Note7 device should power down and stop using the device."
It's a major setback for the South Korean electronics manufacturer.
Samsung (SSNLF) released the 5.7-inch Galaxy Note 7 device in August as a competitor to Apple's new iPhone 7. But customers immediately started complaining that their phones were catching fire.
The company explained that faulty batteries were overheating the device and causing it to ignite. In early September, Samsung recalled 2.5 million devices worldwide.
Samsung offered replacement phones -- but those burst into flames too.
In the past week, an American user reported his replacement phone caught fire, even though it wasn't plugged in. And on Wednesday, smoke started billowing from a replacement Galaxy Note 7 aboard a Southwest Airline plane before it departed, prompting the flight's cancellation.
The U.S. Consumer Product Safety Commission has said it is investigating the incident on the plane.
On Monday, Samsung said that customers who shutdown their phones can "take advantage of the remedies available." But it's unclear what those options are.
