Smartphones have become ubiquitous in today's society. People use them at any time and from anywhere to enrich or enhance their daily living activities such as staying connected with their friends and family, and shopping and paying fees. Though smartphones are an indispensable part of our lives, most people are not familiar with their internal structures, let alone mobile app development. This talk tries to fill the gap by giving an insight on smartphones including three themes: (i) smartphone structures, (ii) mobile computing, and (iii) current issues of smartphone computing research. Finally, information about other smartphone topics of interest to researchers will also be given.
