Samsung continues to refine its Android experience with each new update, and in 2025, One UI 7 stands out as one of the most advanced, user-friendly, and visually appealing software versions ever built for Galaxy devices.
Based on Android 15, One UI 7 introduces deeper AI integration, smoother animations, more efficient battery management, and enhanced customization options. It’s designed not only for the latest Galaxy S24 series but also for a wide range of older Galaxy phones and tablets.
In this detailed review, we’ll explore everything new in Samsung’s One UI 7 — its top features, performance improvements, design changes, AI upgrades, and why it sets a new benchmark for smartphone user experience in 2025.
