Ever been walking your dog while carrying groceries and swiped your phone with your nose?
No, but if I'm the only one walking the dog while at the park my phone is upside down in my pocket because the headphone jack is on the bottom of the phone and I'm also sometimes carrying a bag with dog excrement I picked up from my dog so no one steps in it. The leash in one hand with a bag of excrement in the other does make using the phone a bit of an issue which is why I don't normally touch the phone until after the bag has been thrown in a trash can along the route. Does that satisfy you?
