Today, smartphones have increasingly become indispensable tools in everyday life and becoming mobile devices that everyone can easily approach. Since it is inexpensive to own a smartphone, the number of people using the smartphones is surging dramatically. Park and Park (2014) also claimed that smartphones are not only for the adults, but also available and easily accessible to young children. Our plan therefore was to undertake a survey research to explore the smartphone usage among Malaysian youth aged 11 to 18 years old and its impact on youth’s social life, especially on the social interaction and familial relationship. A theoretical framework with three major theoretical perspectives namely Uses and Gratifications Theory, Actor Network Theory, and Media Dependency Theory was constructed. The framework also encompasses several research areas such as technological communication and smartphone usage patterns, factors affecting smartphone purchase, reasons of smartphone usage, smartphone usage behavioural problems, youth who used technological communication more frequently could exhibit social skill deficits, and manifest higher levels of social anxiety, etc. The theoretical framework has provided grounding base for the research.
