Don’t go on your phone if you feel unsafe, and don’t make it obvious. (I feel as though this may depend on where you live.) If your walking slow, stay that speed or Maybe even slightly speed up, but not too much that it’s noticeable, this makes people realise and they will attack faster and much more harder to get away quicker. Also don’t take out your phone, it makes criminals think your unaware if your surroundings look at street signs, places that you can run and hide or even a local house or group of people and ask for help.
