A Galaxy Watch Ultra 2 owner posted on Samsung's Community forum that their watch wouldn't calculate VO2 Max after a track running session. Android Authority translated the Korean error in Samsung Health: the app says the runner didn't go at least 10 minutes at 4 km/h or faster with a good GPS signal. The owner's screenshots show more than 10 minutes at well over 4 km/h, and they say the GPS was steady. Their outdoor runs in Samsung Health do show a VO2 Max value.

A forum moderator replied that Samsung's developers have confirmed the problem and plan to fix it in a future software update. The moderator didn't give a date.
