SAN FRANCISCO (KGO) --Samsung representatives are standing by at SFO in case people bring their potentially dangerous Galaxy Note7's to the airport.
SFO says Samsung reps are now located in front of security checkpoints. Customers can go there to swap out their recalled phones or get a refund.

Right now, Note7's are banned on all U.S. flights after several reports of fires.
The Note7 already had restrictions since a recall was issued by the company last month. But after one of the models exploded on a Southwest flight earlier this month, the U.S. Department of Transportation banned all Note7's - including the replacements.
Helene Rae and her husband are wrapping up a six week tour through the American southwest. She's proud of one picture in particular, in Monument Valley, Arizona that was taken on her smartphone.
But when she was checking in for her flight on Quantas back home to Australia, she learned that she couldn't take her Samsung Galaxy Note7 on board with her.
"This news came on the recording saying that any Note7, original or the replacement, is banned on all flights," she said.

She was able to surrender her phone to one of the representatives the company has sent to SFO.
The South Korean company says it's working to communicate the ban to travelers by setting up at the most frequently visited airports.
One woman says her husband was flying through Idaho this weekend and learned about the restriction the hard way.
"They started telling him they can't take their phones on their flight, so he ended up at the airport, basically having to just throw the phone away," said Jane Klosteman.
The San Francisco team can transfer all the data from an owner's phone to their replacement on site.
For passengers who may try to sneak a banned phone onto a plane, the Transportation Department says those passengers could face serious fines for transporting an explosive device.
