I use health sync to sync my Samsung activities to my Google fit. The steps are always accurate and appear in Google fit. It will log an activity. Say a 2 hour session on the treadmill. This will log say 12000 steps in Google fit and I can see the activity. It says that there are 120 active minutes. The probable is then something the move minutes either read 0 or are just wrong, when I've clearly been moving for 120 minutes. It also sometime either doesn't record any heart points ( sometimes just says 0 heart points) or the number of heart points is considerably low for say a 2 hour session on the treadmill. I'm not sure what I'm doing wrong. I don't want Google fit to track my fitness activities, but to accurately convert my Samsung health fitness data.
