Smartphone Manners

Today, there are a lot of smartphone manners, but I think that especially walking smartphone is very dangerous. Walking smartphone is doesn't look ahead and hit the person. It's very dangerous for everyone. Because you hit the person and fall down and hurt, you get into trouble with hit the person, and so on. In fact, I do a walking smartphone, too. Also I have been almost hit with each other by a person. So I try to stop the walking smartphone.
