The smartphone can be defined as a handheld device with an intelligent operating system with multiple usages. Its advent in the last decades is undoubtedly one of major technologi‐ cal innovations that has paramount economic and social impacts. The smartphone is today present in all spheres of business and society. For instance, most of the ERP solutions and web applications are available in mobile format. Figures show that the number of subscrip‐ tions has almost surpassed that of the world population and the resource constraints often attributed as major limitations for computation and storage are no longer valid, namely, with the complementarity of the cloud.

Likewise, emerging technologies such as IoT and edge computing promote smartphones as reliable end devices in real-life use cases. As a matter of fact, smart city mobile apps are ex‐ amples of the necessity of the citizens to be acquainted with the efficient use of smart apps. Mobile app companies have betted on innovative minds and the billion dollar global mar‐ ket. But far beyond mobile apps, the smartphone has taken a phenomenal dimension from its physical and sensor attributes. This is very much perceptible in the utilisation of smart‐ phone in healthcare scenarios and medical instrumentation. The multidisciplinary nature of research and development involving smartphones is pushing away the frontiers of knowl‐ edge, hence the need to compile latest advancements in the field in a concise and structured manner as provided by the current book.

This book disseminates smartphone-centric advance research achievements from authors coming from different corners across the globe, namely, Turkey, Mexico, France, Togo, Spain, Japan, and Italy. There are ten chapters covering issues and challenges in mobile mal‐ ware and security, disaster recovery, healthcare, technology acceptance, mobile payment, misuse of mobile phones, education and future networking like positioning techniques. Re‐ searchers, practitioners and postgraduate students planning for MPhil/PhD studies will find ample food for thought. Readers will surely enjoy the array of topics made technically af‐ fordable with deep discussions and analysis. These were the main motivations behind the whole process and quality assurance in the development and realisation of this project.

We would like to express our appreciations to all the chapters' contributors and their respec‐ tive institutions. We feel indebted to the Publishing Process Manager, Ms. Romina Skomer‐ sic, who has accompanied us in this endeavour from the outset. We would like to give special thanks to the InTech technical team for ensuring the quality of the manuscripts. We are very much grateful to the InTech Commissioning Editor, Ms. Anja Filipovic, for the suc‐ cess of this collaboration.
