File System Usage in Android Mobile Phones

Abstract

In this paper, we report on the analysis of data from Android mobile phones of 38 users, composed of access traces of the users' mobile file systems during 30 days. We shed new light on the file usage patterns and present the data in terms of file size distributions, file sessions, file lifetime, file access activity and read / write access patterns. We characterize different distributions and extract conclusions about usage patterns of Android file systems.
