Some users of Samsung Gear and Galaxy smartwatches reported they can't use the watch in standalone mode because it never acquires GPS signal. We identified and fixed the problem, the fix will be included in the next update of the Golf Pad watch app.
In the meantime you can work around the problem using the steps below:
1) Go into Android settings, Date & Time and enable 'Automatic date and time'
2) Finish current round in Golf Pad and start a new round
