A Modern Visual Overhaul

The 2025–2026 update introduces a completely redesigned User Interface (UI) that moves away from the traditional cluttered layout. Taking inspiration from more modern interfaces, the new design features rounded app icons, updated typography, and a streamlined top navigation bar that houses your Search, Home, and dedicated tabs for Movies and Live TV.

Performance Built for 4K

For owners of the Fire TV Stick 4K Plus and 4K Max, this isn't just a visual refresh. Amazon has rebuilt the underlying code, resulting in performance gains of 20% to 30%. This means faster app launches and smoother navigation through content-heavy libraries. Additionally, the new UI expands your home screen flexibility, increasing the number of pinnable apps from six to 20.
