Overview
- 9to5Google cites users seeing batteries run down in roughly 12–15 hours after updating, with some also losing always-on display functionality and only sporadic relief from clearing the cache.
- A Samsung Community post includes a diagnostics screenshot showing wrist detection, BIA, and ECG marked as failed on a Galaxy Watch 4 Classic after the update.
- The reported sensor failures can prevent health tracking and keep the watch locked when wrist detection is required, limiting features such as Google Wallet and notifications.
- Some owners say the update no longer appears in the Galaxy Wearable app, indicating the rollout has slowed or stopped for parts of the Watch 4 lineup without an official explanation.
- Despite the slowdown, SamMobile reports the 44mm Bluetooth Galaxy Watch 4 in India received two updates in one day, including the 1.7GB One UI 8 build, and Samsung has not provided a fix timeline.
