Your eyes should be watching where you are going and scanning your surroundings.Being observant of your surroundings can help you identify potential problems before you're in the middle of them, and identify exit routes, safe places to duck into, and allies on the street. Your mind/ ears should be free to take in the surroundings too, primarily sound. If I hadn't been on the phone, I may have heard foot steps approaching behind me. Be aware of footsteps, rustling bushes, approaching cars, or even arguing voices near by. Being aware is the first step to assessing whether the situation is a threat to your person.
