I have two Samsung Galaxy S4s I've been using for data collectors with Survey123. I've used them successfully in the past, but now they will not connect to the onboard GPS. Both will show accurate GPS locations in Google maps, but both tell me "No position received" in Survey123. I've uninstalled my survey and Survey123 on both, then reinstalled. Same issue. Both say they're connected to the integrated provider, but I get no location. Both have permissions. Ideas?
