vivoactive 3 - onBack not implemented on the device?

o A Descriptive Title
vivoactive 3 - onBack not implemented on the device

o The Environment:
vivoactive 3

o A detailed description of the issue
A user reported that he couldn't exit my app on his vivoactive 3, so I have reason to believe the onBack event isn't triggered on the real device.

In the simulator swiping left does trigger a onBack event.

I've now worked around the issue by implementing the onSwipe event and let the SWIPE_LEFT have do a System.exit().

o Steps to reproduce the issue
Deploy the inputSample on the real device

o Any applicable additional information

o A code sample that can reproduce the issue (in email only if preferred)
