Now that the CPSC is involved and it's an official recall, the FAA has also issued a reminder that hazardous material regs "prohibit air cargo shipments of recalled or defective lithium batteries and lithium battery-powered devices." According to the FAA, if you have one of the recalled Samsung Galaxy Note 7 phones, the only way you can bring it with you is to follow these steps:

Turn off the device

Disconnect the device from any charging equipment

Disable all applications that could inadvertently activate the phone (e.g. alarm clock)

Protect the power switch to prevent its unintentional activation, and

Keep the device in carry-on baggage or on your person (Do not place in checked baggage)

Or, just don't bring it at all, and return the device immediately
