Sputnik ROM is a Samsung-based custom ROM built especially for the Samsung Galaxy S20 FE Exynos (SM-G780F). It brings the full One UI 6.1.1 experience from Galaxy S23 FE and ports it to the S20 FE with many improvements and fixes.
This ROM is perfect for users who want:
- The latest Samsung One UI look
- New Galaxy AI features
- Better performance and stability
- More control and extra options
Samsung has stopped giving major One UI updates to the S20 FE, but Sputnik ROM allows users to enjoy modern Samsung software again. Even though this project is now marked EOL (End of Life), it is still a powerful and stable ROM for daily use.
What Is Sputnik ROM and Its Purpose

The main goal of Sputnik ROM is:
- To bring One UI 6.1.1 to older Samsung phones
- To provide Galaxy AI features
