9 holes walking with phone in bag, never out of bluetooth range. I mention bluetooth because in the past I suspected that losing bluetooth connection stops data transfer and interrupts shot maps.
Shot detecction and shot maps worked fine. One extraneous shot detected between tee and second shot. Extraneous shots were occasionally detected with my older S20 and are not concerning to me. Shot map displayed distances appear to accurate.
I hopefully will be playing 18 tomorrow riding. I leave my phone in the bag, so there will be times when bluetooth connection is lost. Also, the course is fairly remote and hilly, there will likely be times when cell service is lost.
