When I purchased my new LG F6 this week I asked them what the NFC icon was for. The first employee I asked wasn't able to tell me what it was. Today, when I went to pay my bill, I asked the employee working this time, and she told me that it was to make the LTE switch on faster. I got the feeling from both her answer and a tone in which she said that she didn't know, and was saying that just to give me an answer and get rid of me. Can anyone please tell me what the NFC icon is for?
