The article finally suggested parents should not worry about their children spending too much time with their friends because this is what teens needs. In my opinion, the smartphones do have some problems, but we cannot dismiss the benefits from it.

Learning to use smartphones correctly can help children to improve their learning and social skills. But I think it is not a good idea for children to waste too much time on smartphones.Essay on Resistance of a Wire Words | 8 Pages.
