Hi,
I recently moved from iphone and apple watch to the Samsung fold z 5 and watch 6 classic so I'm not sure if this is a fault or not.
Every time I move, my watch logs it as exercise activity. For instance, if I walk from one room to another it will not only count my steps but also add time on to my activity such as increasing my activity time by 1 minute.
I do have auto detect on but I thought this only registered after a few minutes of activity.
Maybe I am just used to my apple watch but my exercise activity seems to be grossly over exaggerated since I started using my samsung watch.
Hope this makes sense.
