I have a Fit2 and it let's me see the amount big calories burn, so it should let you see in the active 2. Probably you have to adjust the settings in the Galaxy Wearable app, if it doesn't help you can still see the amount of calories burn in your Samsung health app.
Thank you for answer, but no. Here no Fit2. Another device class. Here no calories settings. Here Samsung Galaxy Active 2 watch for fitness. Without calories burn show. Without main fitness feature. LoL
