I don't get a little box but On my note 3 when someone calls and i'm using my phone I get 3 boxes on the bottom of the screen: answer, speaker, ignore (or was it do not answer). Answering will take me to the phone app, speaker will just put it in speaker mode and doesn't change screen. Doesn't seem like something new but maybe they changed it up a little. Do you have an image of how the little box with their picture looks like?
