So basically it seems that at least some Android phones are listening and interpreting what is said during phone calls. People have said that they would hear about a restaurant from a friend on the phone, and then cards for that restaurant would show up in google now. Or advertisements would start to show up in google ad services. Or in my case, I got an address over the phone, wrote it down on paper, went to google maps and typed the first two numbers of the address (the street number of the address was four numbers long) before the first suggested address popped up and lo-and-behold it was what I was going to type. This was moderately convenient I suppose, but I am a little uncomfortable with how little I know of the extent to which this is happening.
Has anyone else noticed this behavior? Is it somewhere in some permission that I don't remember accepting, or in the general TOU of the OS?
My main concern isn't really THAT Android does this. Like I said, it can be convenient, and I already ignore pretty much all advertisement without even having to think about it at this point so targeted ads don't bother me so much (though there was one instance where someone suspected they started getting spam emails via this method, which sounds annoying). I am more worried that I don't know where ELSE and how ELSE this information is going/being used.
I'm on a Verizon Note 3, for reference.
