I think the app is adjusting for differences is detects between the way the Active 2 detects steps and the way the phone detects steps. First thing this morning I went for a walk starting with something like 123 steps tracked around the house already. With the phone in my pocket and the Active 2 on my wrist I took a small walk. When I got back I checked the steps in the Samsung Health app on the phone and it showed a total of 3745 "ALL STEPS". When I selected just "MOBILE PHONE" it showed 3419 steps. Without more info from the developer on exactly what is happening, I am satisfied that the "ALL STEPS" is accurate enough for me. Anybody can do similar samples and decide for themselves what to do.
