A:AnswerYes, you can send text responses back using your voice or a feature where you write on the watch face. It's a pretty thick watch even though it's the smaller of the two sizes. While I love the functionality, I might surrender it to my husband, because I think it's still too big/heavy for my wrist and I don't think my wrists are that small for a woman.
A:AnswerTechnically, no, but funtionality would be limited. It will work via wifi (or LTE as stand-alone), but, on wifi, you don't have your phone for text messages, etc. If you get the LTE version (T-Mobile only), you should be fully functional. Best bang for the buck is non-LTE and keep your phone nearby.
A:AnswerThis watch is water resistant to 50 meters, and can be used to track a swimming workout. It's not meant for deep water activities, but should be ok for multiple hand washings.
A:AnswerI believe the largest size it can fit around your wrists is a 44in watch. That had a very big face so it depends on how big you want the watch face looking on your wrist when you check your notifications.
A:AnswerThey have all of the same features, but the 42mm has a smaller screen and a smaller battery. Unfortunately, I don't know which features you're referring to with the Galaxy S8, but I use mine with the S8+ and it works great.
