I am having the same issue with Samsung Health on my Smartwatch. I have tried every suggestion in this feed as well as another (https://eu.community.samsung.com/t5/wearables/galaxy-fit-e-stops-recording-workouts/td-p/1721824/page/2). Nothing seems to work. I see this problem has existed since April at least and Samsung still fails to address it. Not really customer friendly if you ask me. For many people (including myself) this will eventually become a reason to switch to other brands. One thing I have noticed and that might help with the troubleshooting. Quite often (not always) it shuts down when I receive a notification on my watch from another app (whatsapp, gmail, etc). Next time I go running I will try temporarily (during the run) shutting down notifications and see if that helps. Perhaps the times that it shuts down and I have not noticed any notifications, still an app in the background forces it to shut down. My point being, other watch apps might shut it down (unrightfully) for some reason. If shutting down notifications would work, I see this as a work around and NOT a solution. This still needs to be solved I believe and after 8 months it is about time Samsung does something about it. ... View more
