Smartphone addiction is a new phenomenon when a smartphone becomes a necessity in our daily life. This study explores smartphone addiction drivers and their results.

In the result of structured equation modeling analysis, preference of social interaction is not related with smartphone usage behaviors such as usage frequency and usage hours. In the analysis of U.S. users, emotional lift is a driver and in the analysis of Korean users, ease of use and flow are drivers for smartphone addiction. There is a significant relationship between smartphone use and neglect of work in both countries.
