My Garmin vivosmart is doing funny things. On Tuesday, the screen froze, so I had to hold the function button for ages to force it to restart. Since then, it manages to show all my details (heart rate, steps etc) as happening correctly, but any activity I record is shown as 12 hours earlier. The time etc is correct and all other times are correct.
Obviously, it's not the end of the world, but it is a bit annoying. Any ideas how to get it to record properly?
