You're driving in the car with your phone mounted on the dashboard and it rings. What do you do? If you take your hand off the wheel, reach across the dashboard and slide the answer button, you might veer into another lane by the time your mom starts talking on the other end.
Fortunately, with Samsung's new Smart Call Accept feature you can answer the phone and have it turn on the speakerphone with the wave of a hand. You can control your music player with Smart Gestures, allowing you to wave right past that Taylor Swift song your wife snuck onto your playlist. You can even cycle through open tabs in the Web browser with gestures.
