After installing the One UI 8 Watch update, many Galaxy Watch users have noticed a sharp increase in stress notifications, even when they report feeling calm. The issue seems related to the stress measurement algorithm, which may have been affected by recent changes in the update.
The One UI 8 Watch release, one of Samsung’s largest smartwatch updates, appears to have introduced a flaw in the stress detection system. Reports indicate that models such as the Galaxy Watch 7, Galaxy Watch 8, and Galaxy Watch Ultra show higher stress readings than before. This issue emerged shortly after the update’s rollout.
“Some Galaxy Watch owners are seeing unusually high stress alerts even when they’re not feeling stressed,” concluded Android Authority.
Samsung’s wearable devices use metrics such as heart rate, heart rate variability, and activity levels to estimate stress levels. When elevated readings persist, the watch notifies the wearer through alerts.
It’s uncertain why the sudden increase in stress readings occurred. One possibility is that Samsung refined the detection algorithm to identify more subtle signs of stress that earlier software versions may have overlooked. However, this calibration may have made the system overly sensitive, causing false alarms.
