A:AnswerSince the watch connects to the phone using bluetooth and does not have its own cellular connectivity, it could only make an emergency call if it is still within range of the phone.
A:AnswerDon't know for sure because Iam not a swimmer. Go to utube any type in Galaxy swim apps. I would guess there are some out there. They have Under Armor apps not sure if any have swim apps.
A:AnswerThis particular series does not have that feature, however, they do have one that will do just that but there is an additional charge through your carrier. I opted not to purchase that particular one.
A:AnswerThe Heart rate monitor on the Galaxy watch seems to be quite accurate as long as the band is snug enough for good contact with your wrist. I recently had a Heart attack so this feature was very important to me, I have compared the heart rate feature to my blood pressure monitor and they always read within a couple beats of each other as long as the band is snug. I am using the band that came with the watch, it is quite soft and stretchy and even when snug is quite comfortable. Hope this helps..........Rodney
A:AnswerYes. The watch uses the same language that your phone is set to. So, as long as your phone is set to display Portuguese, your watch will display the same.
