A:AnswerYes, as long as you are connected to your phone via Bluetooth.. I have used this feature when in the pool and had my phone out on the table. It has a built in microphone, so you can talk directly into the watch. You can also start a call from the watch. This also works with text messaging.
A:AnswerThe larger watch will go about twice as long between charges.
I have the 42mm model, and I could go almost 3 days between charges, but I have gotten into the habit of just recharging every other night.
A:AnswerMake sure your height is correct in the SHealth app. It uses the average. Additionally it doesn't count your steps unless you walk more then about 15 steps. I thought this was a problem too until I played with it for a few hours
A:AnswerIt's a good choice but you'll have to rinse it off and pat it dry. The sensor on the back can act up if there are any chemicals such as soap, chlorine, or salt from your sweat. Shouldn't be a big deal. You can put a short cut in for water mode on the drop down screen. This sounds like something you'd want to do. This tells the watch to not keep lighting up as you swing your arms while running or activate the touch screen while under water. The cool thing is when you exit water mode it does a routine to expel any water that got into the case though I have no idea how!
A:Answeryes, you can download 1 gigabyte of music on the watch and listen to it without the phone being near. I use mine to go running. I've got 250 songs on my phone and created a playlist of 45 songs that I downloaded to my watch that i listen to while running- i leave the phone behind.
A:AnswerSadly, it does not work with Google Voice ( I would recommend a Moto 360 2nd Gen if that is the type of capability you are looking for out of your wearable! This watch has been updated to use Bixby (Samsung's Voice based Assistant) This cannot use google voice due to the fact that it is using the Tizen OS Platform instead of using Android Wear.
A:AnswerIt's a program through Samsung wherever you buy. You will submit a proof of purchase to Samsung. It's like a mail in rebate type promo but the strap is sent from them directly not retail outlets.
