Vivoactive users can define whether it uses the left or right fist watch. I would like to test this feature on the simulator but I do not find it normal?
There's no way to test this in the sim, but I'm not sure why you'd need to. The only real difference is which side the button is on, but it acts the same, you still swipe right to left for onBack, 0,0 is still the upper left, etc.
When a user switches, the thing they want to do is re-calibrate the compass or it will be 180 degrees off for apps and things like the native heading data field, but that's really the only thing.
