Thanks. I just checked that and it is set to Every Hour. I'm starting to wonder if there is something wrong with my Gear S2. It certainly doesn't seem like it is updating every hour. I also just walked from my work desk to the kitchen and back. I was at 503 steps before I left. I left my phone at my desk. When I got to the kitchen it still said 503. I also watched it for the second half of the walk. I then counted the steps as I walked back to my desk. It was around 35. When I got to my desk the Gear S2 updated to 541. So it never tracked the steps to the kitchen and hasn't updated for it. The past two days I've been very surprised at how low my step counts have been. I typically measure them by my phone which has been much higher than on the watch. The strange thing is that I've always had my watch on and often wouldn't have my phone in my pocket.
I'm becoming less and less impressed with my Gear S2. I don't use the bevel that often and typically just scroll with the touchscreen. At this point I'm wondering if my Gear S2 is not working correctly and that I should try getting a new one (I'm still in the BB 15 day return policy, obviously) or if I should instead try a Moto 360.
