The call from the South Korean company, the world's largest smartphone maker, comes after U.S. authorities urged users to switch the Galaxy Note 7 off and not to use or charge it during a flight. Several airlines around the world asked travelers not switch on the jumbo smartphone or put it in checked baggage, with some carriers banning the phone on flights.
In a statement posted Saturday on its website, Samsung asked users around the world to "immediately" return their existing Galaxy Note 7 and get a replacement.
"We are asking users to power down their Galaxy Note 7s and exchange them as soon as possible," said Koh Dong-jin, Samsung's mobile president. "We are expediting replacement devices so that they can be provided through the exchange program as conveniently as possible."
Consumers can visit Samsung's service centers to receive rental phones for temporary use. Samsung plans to provide Galaxy Note 7 devices with new batteries in South Korea starting Sept. 19, but schedules for other countries vary.
Earlier this month, Samsung announced an unprecedented recall of 2.5 million Galaxy Note 7s worldwide just two weeks after the phone was launched. That move came after Samsung's investigation into reports of fires found that rechargeable lithium batteries manufactured by one of its suppliers were at fault.
The U.S. was among the first countries to take a step following the recall. Late Friday, the U.S. Consumer Product Safety Commission urged owners of the phone to turn them off and leave them off. It also said it was working with Samsung and hoped to have an official recall "as soon as possible."
The recall by the safety commission will allow the U.S. Federal Aviation Administration to ban passengers from carrying the phones on planes. The FAA already warned airline passengers late Thursday not to turn on or charge the Galaxy Note 7 during flights and not to put the smartphone in their checked bags.
Scandinavian Airlines said Saturday that it has prohibited passengers from using the Galaxy Note 7 on its flights because of concerns about fires. Singapore Airlines has also banned the use or charging of the device during flights.
Samsung said it had confirmed 35 cases of the Galaxy Note 7 catching fire as of Sept. 1, most of them occurring while the battery was being charged.
