Up until today my samsung was doing great counting my steps, but today I went on walk at the park (my samsung was on because I was using it to text) but when I got back in the car, I realized it didn't count any of my steps because it said that I had walked 0 steps that day. Is there any way to fix this? I also can't rotate my phone for some reason while I'm playing games so I think that might be part of the same problem.
