If you've noticed your Galaxy Watch Ultra 2 glitching with VO2 Max readings, you're not alone. Several users have reported that their smartwatch isn't showing VO2 Max readings after track runs.
That's despite the smartwatch being able to track GPS, pace, and activity time, so there's really no reason for it to not be able to record VO2 Max readings.
This issue appears to be limited to track runs, with the bug making Samsung Health think that not enough data is available to track VO2 Max.
Typically it requires running data for at least 10 minutes at 4 km/h or faster. Users who ran for longer than the minimum duration still don't see the VO2 Max data in Samsung Health, even when the other metrics from the run are tracked accurately, and the GPS signal was solid.
There doesn't appear to be a problem with outdoor rooms, as users have checked whether this was an issue with those sessions as well found that Samsung Health was able to calculate VO2 Max for those runs as it always as. VO2 Max readings are working normally for other activities as well.
This issue was first reported on Samsung's official forums, and a moderator has replied that the company is aware of the issue and that a software fix is being developed. No timeline has been provided, though, as for when this update will arrive.
