Airline passengers in the US have been warned not to switch on or charge their Samsung Galaxy Note 7 mobile phones when in-flight.
The alert was issued by the US Federation Aviation Administration which also advised against packing the devices into checked-in bags.
Qantas and Virgin Australia are also reported to have also told customers not to charge or use the phone during flights.
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.”
Samsung last week recalled 2.5 million Note 7 devices after confirming 35 cases of its rechargeable lithium batteries catching fire.
The company offered to replace devices from September 19 after an investigation found “an isolated battery cell issue” following reports of the phone exploding during or after charging.
Samsung said: “There have been a small number of cases reported globally and we are currently conducting a thorough inspection with our suppliers to identify possible affected batteries in the market.
“However, because our customers’ safety is an absolute priority at Samsung, we have stopped sales of the Galaxy Note7.”
