Samsung Galaxy Note 7 users traveling by plane have been warned by the Federal Aviation Administration (FAA) not to switch on or charge their phones when on board the plane.
The FAA also advised against packing the phones into any checked-in luggage.
Last week, Samsung recalled the Galaxy Note 7 smartphone after reports emerged of the device exploding during or after charging.
Qantas and Virgin Australia have also told customers not to charge or use the smartphone during flights.
Samsung has said that battery problems were behind the phones catching fire, but that it was difficult to work out which phones were affected among those sold.
The FAA said: “In light of recent incidents and concerns raised by Samsung about its Galaxy Note 7 devices, the Federal Aviation Administration strongly advises passengers not to turn on or charge these devices on board aircraft and not to stow them in any checked baggage.”
Following Galaxy Note 7 recall, Qantas said on September 8 it was “requesting that passengers who own [the devices] do not switch on or charge them in-flight.”
The Galaxy Note 7 was launched last month and has been otherwise generally well-received by consumers and critics.
Some 2.5 million phones have been shipped globally.
Samsung has said customers who have already bought the phone will be able to swap it for a new one and that it would take about two weeks to prepare replacement devices.
The US trade group Airlines for America said it was “closely monitoring” the Galaxy Note 7 issue and that carriers in the US would make their own ruling over the use of the phone on board.
An Airlines for America spokesperson said in a statement:“Each individual carrier makes determinations, in compliance with FAA safety rules and regulations, as to what is permitted to be carried on board and in the cargo hold.”
South Korea-listed shares of Samsung Electronics were down close to 3% in early Friday trade.
