I just checked into my Flight, UA2, from Singapore to San Francisco (SIN->SFO). Traditionally when checking in to this flight, I'm asked questions about sharp objects, has anyone given me anything to carry, did i pack my bag, has my bag been under my control. This time, the security person had one, and only one question (That's actually what he said, "I only have one question for you" - They held up a sheet of paper with "Galaxy Note 7" on it, and asked me if I had one in my possession, either checked or carry on luggage. That's it, that's all they cared about. They really don't want those phones on planes in any form.
