I'm using the second beta release on a Galaxy Watch 5 with all updates to apps on both phone and watch (beta versions of Watch 5 Manager and Samsung Health).
I've noticed while tracking my morning walk (Samsung Health Exercise) the GPS generated map when finished and saved shows my path all over the place resulting in a walk that should be around 2.25 miles sometimes being 3 to 4 miles (when Wi-Fi is on). I recently tried the same walk with Wi-Fi off and have found that the GPS generated map is much smoother (closer to the actual path I walk) and more accurate.
