Galaxy Watch 7’s November 2025 Security Update now expands for LTE models

Samsung has started delivering a new update for the Galaxy Watch 7 units, which integrates the November 2025 security patch; however, it was only limited to the Wi-Fi models, and now, the company is providing the update for the LTE units as well.
To recall, after a long-running One UI 8 Watch beta series, Samsung began the process of releasing the stable version for the Galaxy Watch 7 models, a few weeks ago and thereafter followed by the new November 2025 security update, but it was still limited to the Wi-Fi variants.
Now, Samsung seems to be looking towards expanding the November 2025 security update for the LTE-based Galaxy Watch 7 models, as indeed the update is spotted available in the home country, South Korea and is expected to expand to even more countries over the coming weeks.

At the same time, the latest firmware for the Galaxy Watch 7 (LTE) models has been identified with the BYK1 version number. However, it’s just a minor security patch that significantly focuses on improving the wearable’s overall security, core functionality and performance to provide a secure user experience.
Additionally, the update is further topped up with the Wear OS 6-based One UI 8 Watch, and thus, it significantly brings a few improvements for the existing major features, such as Bedtime Guidance, Vascular Load, Running Coach, and Antioxidant Index. This apparently aims to provide a healthier and well-maintained experience to the users.
