Thanks for the tips Neil.  I used the settings you recommended and it seems to be working fine.  I've done two six mile race walks.  If I get a call it returns to the watchface, but the timer doesn't stop.  It is still kind of sad the watch doesn't work as touted, though.  ... View more

I have the same problem.  My watch doesn't even give me an error message.  It just stops the workout tracking and goes back to my watchface.  My Gear S3 Frontier started doing the same thing when it was about 2 years old.  I got the Galaxy watch for Christmas and it's been doing it on and off since I got it.  I had to turn off the workout autodetect because once I was walking and after about 1/2 mile it detected I was doing elliptical training!  What?!  Also at the end of a ten mile walk it all of a sudden said I walked 62 miles.  I'm not the Flash!  Please fix this or I'll have to give up on Samsung watches which would be too bad because I love my Samsung phones (I have a Note 10). ...
