Hi, I recently bought a Galaxy Fit 3 and there are issues with step count. Samsung Health doesn't count steps from the band if it's not connected to the phone via Bluetooth. To verify this - 

My step count on the band was 3250 but when I connected to Samsung Health it went down to 3052.

So I disconnected band from the phone and walked 40 steps leaving the phone on a desk. Band step count went to 3091. I connected the band to the phone, synced with Samsung Health and step count went back to 3052 on the band.

Effectively lost 40 steps. This is obviously a glitch because one doesn't always have their phone in the pocket for example at home or office.
