What's wierd is my netflix has worked fine no issues at all so I dont know honestly had only one hiccup sometimes when I swipe to home from a app it will have a delay in between showing the home screen
I haven't ever need much from a watch love my Fitbit versa good enough for me 4 days of battery life wanted one less thing to have to charge plus use it for sleep tracking
Turn of favorites in recent app menu it makes it work a little smoother make sure you turn off Samsung pay on home screen then all have do is swipe right on the middle line
The update was for carrier versions not the unlocked version. You will either have to flash the carrier version or wait until the release the unlocked version. There are threads on how to flash the carrier version hope that helps
I use the gestures 100% of the time essentially same experience as the buttons I like samsungs implementation of it compared to my pixel. I use the swipe right alot works perfectly just like the double tap did
You might want to check that because even though it says 18 months I know sprint does the galaxy forever program with the flagship samsungs you can upgrade after 12 months to the new galaxy. It would show under your device agreement on your my sprint page
