GoKawiilSamsung confirms VO2 Max bug for track running on Galaxy Watch Ultra 2
Galaxy Watch Ultra 2 users report that the watch fails to calculate VO2 Max readings specifically for 'track running' sessions, even when pace, duration and GPS signal all meet the required thresholds. Outdoor running sessions are unaffected, with VO2 Max data recorded normally. Samsung has acknowledged the issue and says a fix will arrive in a future software update.
