The company released a maintenance update specifically targeting what sources described as a strange sensor-related issue
affecting the Galaxy Watch 4 series. This preliminary update is designed to stabilize device performance and ensure core hardware functions correctly before users are prompted to install the more substantial One UI 8 Watch operating system. The patch is being distributed over-the-air, and availability may vary by region and carrier.
The sensor fix precedes the much larger One UI 8 Watch update, which is reported to be approximately 1.7GB in size. This major release, based on Google’s Wear OS platform, is expected to introduce a host of new features, user interface changes, and functional upgrades to the two-year-old smartwatch line. According to the release notes, the update also incorporates the security patch, enhancing the device’s protection against known vulnerabilities.
Major Wear OS updates typically bring improvements to health and fitness tracking, new watch face APIs for developers, and better integration with the Android ecosystem. While Samsung has not released the full changelog, updates of this magnitude often overhaul system performance and battery efficiency, as noted in previous One UI Watch releases.
Samsung issued the corrective patch in direct response to user reports and internal findings of sensor malfunctions on the Galaxy Watch 4 Classic. While the company has not detailed the exact nature of the problem, such issues in wearables can often affect key functions like heart rate monitoring, step counting, or GPS tracking. By releasing a targeted fix, Samsung aims to prevent these hardware-related bugs from carrying over or being exacerbated by the new One UI 8 Watch software.
The specific root cause of the sensor malfunction has not been publicly disclosed by Samsung. Furthermore, a detailed timeline for the global release of either the patch or the final One UI 8 Watch update has not been provided. It is also unclear which specific sensors were affected or if the issue was widespread across all Galaxy Watch 4 units.
Galaxy Watch 4 series owners will likely receive the smaller, corrective update first. Following its installation, the device will be prepared for the major One UI 8 Watch update, which is expected to be released in a phased rollout. Users should anticipate two separate update notifications in the coming weeks.
Owners of the Galaxy Watch 4 and Galaxy Watch 4 Classic can check for the update manually through the Galaxy Wearable app on their connected smartphone. It is standard practice to back up watch settings and data before installing a major OS upgrade. To ensure a successful installation, the watch should be charged to at least 50% and connected to a stable Wi-Fi network.
