I have been using the Vivofit for a few months and recently bought the soft strap HRM. I am following the instructions on how to record the heart rate. I have found recently after going for walks that it is not saving my walk activity. I tried it randomly to try and figure it out and it will record no problem. Not sure what i am doing wrong, seems to record sometimes, but not after a walk (which is about 45 mins - 1 hr long). Also, I have recently downloaded the Garmin Fit app to use in conjunction with Garmin Connect app. I am wondering why it wouldn't be recording my HR data. I am using it with my Samsung Galaxy Note 2. I have had no issues thus far and am very happy with the Vivofit. Any suggestions would be helpful. Thank you
