Can Modular Phone Accessories Finally Evolve Beyond MagSafe?

Finnish company Jolla is reviving its modular back cover concept for smartphones, joining a renewed industry interest in modular phone accessories seen at Mobile World Congress 2026. While Apple's MagSafe has been the most successful magnetic accessory system since 2020, it remains limited in data-transfer capabilities. New concepts from companies like Tecno and Belkin suggest the industry is moving beyond simple magnetic attachment toward richer modularity using both magnets and pin connectors.
