A:AnswerThe band is eazaly removed from the case / little rectangular mechanisum. I have no data on colors or availabilty of replacement / after market bands.
A:AnswerThat is a great question, Lin! The Galaxy Watch Fit2 is only able to sync with your mobile device when it is connected to Bluetooth. Thank you for asking this question. ^Kayla
A:AnswerHey there, Sam. To experience all of the wonderful features the Galaxy Fit2 has to offer, it would need to be worn as a watch. Thank you for asking this question. ^Kayla
A:AnswerYes, I noticed the deerance, unlike my Gear Fit Pro2 that I have used in the past. My new Galaxy Fit2 not have 100% real time conectivity / updates. From time to time I recive "Band backed up" notice on my phone. So if your phone and Fit2 are seperated the Fit2 monitors, collects and maintains data. I don't know the logic sequest that are requied but the data is transfered to the phone post activity. Note: just a guess but maybe that heps with the unbelivable (7+ days) battery life.
