Abstract :

Smartphone is one of the most innovative invention that is the closest with our everyday life. Invention and development of smartphone brought a lot of social issues, changed our life, and it is still changing. As the number of smartphone user increase and various devices and smartphone applications are being made, instruction for smartphone became more diverse and complicated, and smartphone users react more sensitively with function of device, and utilization of application. In order to satisfy this, manufacturing companies devote all their energy on improvement of efficiency and development of application, however, they have not been able to give a clear answer for performance degradation which is inevitable issue on using various applications. In this paper aims to find cause of frequent IO in actual use by taking degradation of smartphone as a topic and collecting and analyzing IO trace information of users.

Keywords :

: Android, Smartphone, IO Characterization
