When I first down loaded ANY go app I ( not knowing the difference) tried the Go 4 app, whilst it installed on my android phone, it would not work with my P3adv. Then I saw I needed the Go app.
Since the Go 4 app would not work with my P3Adv I did not try any other function that it might or might not have offered.
The above pages seem to make the point that a P3 requires the Go app and a P4 requires the Go 4 app.
Presuming those pages to be correct and if you do in fact have a P3Std might it not be better to use the Go app rather than the Go 4 app?
