I have been having an issue the last couple weeks where I take my Galaxy 4 watch off the charger, put it on, take the dogs for a 30 minute walk, only to look down and notice not a single step was detected. Once is a fluke but multiple times is an issue. I have tried turning the wash off and back on. There are no updates. I have to make sure to tap the screen to wake is up and also select a walk workout to get it to start counting steps. Any advice?
