The Watch I Did It For You Onlinebad news trailing Samsung and its defective Galaxy Note7 smartphone continues as the Federal Aviation Administration (FAA) has issued yet another stern warning about the device, this time to airline companies instead of passengers.

"Following a Consumer Product Safety Commission recall of the Samsung Galaxy Note 7, the FAA is issuing general guidance to airlines about the rules for carrying recalled or defective lithium devices on board aircraft as cargo or in carry-on luggage," read the notice posted on the FAA website on Friday.

There have already been a number of passenger reports of airlines making special announcements before trips advising customers to turn off their Samsung Galaxy Note7 devices, but this official guidance from the FAA takes things ever further.

"U.S. hazardous material regulations prohibit air cargo shipments of recalled or defective lithium batteries and lithium battery-powered devices, and passengers may not turn on or charge the devices when they carry them on board a plane," the FAA statement continued.

"Passengers must also protect the devices from accidental activation, including disabling any features that may turn on the device, such as alarm clocks, and must not pack them in checked luggage."

This latest statement follows the FAA's earlier advisory on Sept. 9, which "strongly advise[d]" passengers against turning on or charging the devices while on a flight.

In addition to the warnings about the device in aviation circles, New York City's MTA subway also issued a warning on Wednesday, asking passengers to avoid turning on or charging the device on the nation's largest subway system.
