Smartphones have become integral to all facets of education, transforming school management teaching, and learning thanks to their user-friendliness, multifunctionality, and widespread adoption. In this study, a "smartphone" is defined as a portable, Internet-enabled mobile device that supports educational applications and instant communication. We explored the strengths and weaknesses of smartphone use by school administrators and teachers, from the viewpoint of school principals. We employed semi-structured interviews to collect qualitative data from a study group of forty Turkish school administrators during the 2024-2025 academic year. Our descriptive phenomenological design was supported by content analysis, which involved coding the data, identifying themes, organizing them, and interpreting the findings. The results revealed that smartphones streamline communication, improve time management, aid in emergency responses, foster collaboration among school actors, promote parent engagement, and facilitate efficient data handling (aligning with global findings on mobile technology in education). At the same time, participants noted challenges including technostress, privacy concerns, and distractions. These challenges are exacerbated by constant accessibility pressures and digital inequalities, deepening the discourse on smartphone use in education from school administrators' perspectives. In summary, our study offers both theoretical and practical insights: it extends Uses and Gratifications Theory to an educational administration context and provides guidance on harnessing smartphones' operational benefits while mitigating their challenges.
