The Samsung Galaxy S21 FE, a popular mid-range phone from early 2022, now runs its last major software version. Samsung started sending out the Android 16-based One UI 8 update this week. This closes the four-year OS support period for the device. It includes fresh tools for daily tasks, better app handling, and security fixes. The rollout began in Asia, with more areas to follow soon.
Update Details and Rollout Schedule
Samsung released the update on October 23, 2025. It carries firmware G990EXXUIHYJ2 and weighs over 2GB, so users should connect to Wi-Fi first. The package adds the September 2025 security patch.
For now, Exynos versions in Vietnam and Thailand get it first. Snapdragon models and other countries will see it in the next few days. Samsung plans to reach all eligible phones by November 2025.
The Galaxy S21 FE launched with Android 12. It moved to Android 13 in 2022, Android 14 in 2023, and Android 15 earlier this year. Android 16 marks the end of big changes. Quarterly security updates will continue until 2027.

How to Install the Update
Owners of the Galaxy S21 FE can check now. Go to Settings > Software update > Download and install. If it’s not there, wait a bit as it rolls out in waves.
Keep your phone at 50% charge or more. Back up files first to avoid issues. The process takes time due to the file size.
