In my case the problem has to do with walking with a Gear Fit 2. I have a custom-made watch face that gives me steps, miles and floors in a large font so I don't have to wear my glasses while exercising. Unfortunately Samsung won't allow me to SEE that watch face because a few minutes into my daily walk the Walking Tracker autostart "feature" in Samsung health pops up and blocks access to my new watch face. I can't even tell what time it is since the time font size of this unwanted "feature" is too small to see without glasses! When I go to "Settings" and then down to "Workout Detection" it does have a list of activities but all I see are Cycling, Elliptical Trainer, Rowing Machine and Dynamic Workout. There is nothing there about walking! Samsung, the inability to have control over this tracker is extremely annoying... not all of your customers buy your watches to be autotracked!
