Why This Matters
The One UI 7 update reaffirms Samsung’s commitment to supporting older flagships, even as newer models like the Z Fold6 and Z Flip6 take center stage. While the Z Fold4 and Z Flip4 miss out on advanced AI tools like Audio Eraser or Drawing Assist (reserved for 2024–2025 devices), the core improvements ensure these foldables remain competitive in performance and security.
Samsung always puts user experience and security first, ensuring that even devices like the Galaxy Z Fold4 and Z Flip4 stay ahead of the curve in the evolving technology landscape.
