Battery problems
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.
"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," the FAA said.
Following Samsung's recall of its Galaxy Note 7, Qantas said on Thursday it was "requesting that passengers who own [the devices] do not switch on or charge them in-flight."
