Samsung Gear S3 update improves GPS performance. You will now get even better performance from the best SmartWatch in the world, with an update to the GPS on the watch. While knowing exactly how far you are from the hole on Number 5 is great, you will now be able to navigate while driving or walking just from your watch. Think about it. Never lost again. Of course, it gets annoying when the watch tells you you are only ten yards closer to the hole after your last duff shot. The S Health app will also be more reliable. If you haven't joined the wrist computer revolution yet, you should take a look at the S3. Amazing stuff.
