many who switched from phone to smartphon , there are many reasons why we switched. one of which is the features that make a person in awe , including me :) is fun to play with a smartphone to lose track of time . many hours interacting with it without being bored . At that time there was one of my classmates who were playing smartphone recess time , I immediately look for the paper in the desk drawer , and immediately draw him with a very good position .
               I can say that this smartphone viruses and friend . it all depends on you . it would be a virus if you use it without a time limit , so you will forget that you have to do the job it should . he could be a friend when you are lonely and optimizing other benefits such as improved communication would with anyone ,
