Samsung has released a new software update for its latest fitness tracking band, the Galaxy Fit 3. This is the sixth software update since the device launched and arrives ten months after the previous update.

The latest Galaxy Fit 3 update, which is currently available in South Korea, carries firmware version R390XXU0AZA3 and has a download size of 17.42MB. According to the update's changelog, it brings the January 2026 security patch along with stability and reliability improvements.

The update is not yet available in markets such as Europe, India, and North America, but it could roll out to those regions in the coming days.

Samsung launched the Galaxy Fit 3 in early 2024. It runs RTOS, a lightweight operating system that does not support the installation of third-party apps. Since launch, the fitness tracker has received only one major update that introduced new and improved features.
