U NEED TO KNOW THIS if you're getting this for your watch. I installed it on my galaxy watch 4 THINKING it was free. It isn't free and it's JUST the alexa voice button. Nothing else or more and not even free. Once you install it, u have to register it to your Amazon account and then it has you age that is free for 7 days and then you'll be charged. I am uninstalling. Guess I'll have to deal with Bixby.
