Just got a galaxy watch and enjoying it so far. However inevitably as with any wearable navigation is challenge with less screen real estate and less buttons.
With this in mind DOUBLE TAPPING the back button needs to be a programmable shortcut, as it is with the home button.
Personally I'd use to for quick access to the recent apps page which currently requires too many clicks and rotations. (double tapping home is already mapped elsewhere)
Was wanting to do the same. I have an app programmed into double tap home button but could really use the second shortcut. Neither app can be opened via the phone but need to be opened in a hurry. Any shortcut would help other than using widgets.
Will post on here if I have any luck. Would appreciate if you could do the same.
