Consumer agency says Galaxy Note 7 owners should stop using phones

The South Korean manufacturer last week recalled the Note 7 in 10 markets including the United States, saying the phones’ batteries were prone to catch fire. The U.S. Federal Aviation Administration late on Thursday said travelers should not charge the phones while in the air or stow them in checked luggage.

“We plan to expedite new shipments of Galaxy Note 7 starting from this week in order to alleviate any safety concerns and reduce any inconvenience for our customers,” Samsung said in a statement in response to the FAA advisory. Shares of the South Korean company fell 3.9 percent on Friday.

For months, pilots and plane makers have raised concerns about lithium-ion batteries, which are used in many consumer devices ranging from phones to laptops to toys. Top airlines banned hoverboards during the Christmas holiday season, and the U.N.’s aviation agency prohibited shipments of lithium-ion batteries as cargo on passenger aircraft.

Several airlines said they are taking a closer look at the Samsung smartphones. American Airlines Group Inc., the world’s largest carrier, said it was in touch with the FAA about the phones.
