@Mercusio Sorry that you feel that way. This "auto sensing" isn't something new, it has been on previous Samsung watches. I have always found it hit or miss. If I positively want an activity tracked, I start the tracking manually.
Thanks, @LongHiker. That may be, but in this offering, as a enticement to upgrade my watch and my ZFlip at the same time, the Shop app and supporting material mentioned this feature, along with other enticements like 3 months free Spotify, 6 months free SiriusXM, and 4 months free YouTube Premium. All of those were a wash as well -- they were basically the same "for new users" offers you can just get on your own, but Samsung actually added them as line-items on the invoice! And then they tracked shipment of them like I was getting something special. Your post actually helps make my point even more! If it's an existing feature, that doesn't work all that well, why in the WORLD would they promote it as a reason to upgrade when I was going to do it anyway? Some marketing VP at Samsung should be fired and they need to look for sharper minds. This was a chump move that needlessly sullied their reputation with many like-minded and loyal customers.
