I bought a newer AIS receiver to work with my Galaxy S6, it didnāt work. I contacted BoatBeacon and explained the problem; and after a few e-mails back and forth they had a free update available on Play Store within an hour after the solution was implemented. I used BoatBeacon on my Galaxy S6 with my old AIS receiver from Panama to Texas and was never concerned about ships or commercial vessels passing too close to my sailboat.
