Galaxy Watch Ultra 2 Isn’t Displaying VO2 Max for Some Activities
A missing metric disrupts track workouts
The Galaxy Watch Ultra 2 can log a run without showing one of its most useful fitness measures. Some owners say the watch fails to calculate VO2 Max after they choose “Track Running” in Samsung Health.
That gap can leave a carefully recorded workout feeling incomplete. VO2 Max estimates how effectively the body uses oxygen during exercise. It can help runners follow changes in aerobic fitness over time, although it should not replace medical advice or a broader view of health.
In a Samsung Community post, one user shared screenshots of a track workout without a VO2 Max reading. Samsung Health appeared to say the runner had not spent at least 10 minutes moving at 4 kilometers per hour or faster with a strong GPS signal. Yet the workout data showed more than 10 minutes at speeds above that threshold. The user also reported steady GPS coverage.
Other running sessions still produce readings
The problem does not appear to affect every run. The same user showed outdoor-running records with VO2 Max readings. That contrast suggests the glitch centers on the “Track Running” activity rather than a complete failure of the watch’s fitness tracking.
For runners, the distinction matters. Track workouts often involve planned intervals, repeated laps and controlled pacing. When the watch records those sessions but omits a key metric, users may wonder whether they need to change settings, repeat the workout or trust the rest of their data.
Still, one reported case does not establish how many Galaxy Watch Ultra 2 owners face the same issue. The available details point to a specific activity mode, while outdoor runs continue to generate readings for at least some users. That makes the problem frustrating, but not evidence that all VO2 Max tracking has stopped working.
Samsung says a software fix is coming
There is a clear reason for affected runners to remain optimistic. A Samsung moderator said the company’s developers confirmed the issue and plan to address it in a future software update. Samsung has not shared a release date.
Until that update arrives, users who want a VO2 Max reading can try recording an outdoor run instead, since that activity reportedly works. However, runners should not assume that changing activities will suit every workout or preserve the same track-specific details.
The Galaxy Watch Ultra 2 still offers useful workout tracking, but this glitch exposes a weak point: a watch must interpret activity data consistently, not merely collect it. A targeted software fix could restore confidence in track-run results without changing the workout itself. For now, owners can keep logging sessions and watch for Samsung’s update.
