I've had a Vivofit 4 for a couple of years. Suddenly I noticed that the step counter display would switch to the clock. When I cycled it back to the counter 200-250 steps had disappeared. I thought I must be wrong but last night it happened twice in a row and wiped out a total of more than 400 steps from my data. This afternoon I completed a walk and the reading was 3360 steps. A few minutes later, in the house the clock face was showing. Back to the counter and now it is 3060. On that same walk, which was relatively brisk and lasted more than 15 minutes, no indicator came on for continuous exercise and none was recorded. I see that over the past years others have reported similar problems. Can anyone help?
Regards
David
