This study aimed at exploring the potential of smartphone use in education with a particular focus on secondary schools. The literature review provided massive methods and applications of the smartphone in teaching and learning plus the challenges that surround it. The review made it possible to identify that there is a group of teachers who perceive the use of the devices as pedagogical tools, and another group of teachers that are against or have a reservation towards its inclusion in education. Students deemed the smartphones as highly necessary compared to teachers. From a literature perspective, it can be that some teachers are immigrants; therefore, they have difficulties in adopting or adapting to the trend. The study suggested that it is essential to try out some projects, such as teaching students with smartphones, especially in developing countries like those in sub-Saharan Africa to yield comparison against traditional teaching and learning.
