Just got this Vivosmart 4, charged it fully, took it for a run (where it was working correctly), and then went for a walk at which point it started flashing a triangle (Garmin logo?) and became unresponsive. Well, the support pages say to hold the power button and reset the device, however this device doesn't have a power button ... so.. do I take it back to the store and return it?
Kind of worrying that a brand new device is already acting buggy...
