Vivosmart 5 Reboots

This has happened twice, where my vivosmart 5 reboots when starting an activity.

Steps to reproduce:

1. Select Activities > Walk
2. Device sits for several minutes trying to establish GPS
3. Device finally gives up and asks to retry
4. I tap twice and it proceeds to start the activity 
5. Device sits at 0.0 for the longest
6. I keep tapping and nothing happens
7. I hold the button down briefly and nothing happens
8. I long hold the button and the triangle appears and then the device reboots
