I think my questions aren't coming across as clearly as I want them to. I have used my iPhone on airplane mode for offline Google Maps, Gaia GPS, and AllTrails, in Colorado, Utah, and the Northern Woods of Maine; I also had an iPad with me, loaded with the same apps, but realized the hard way that it didn't have a GPS chip. I am looking for a tablet with expandable memory to do the same thing, and prefer an 8" screen, as it is functional to search and temporarily mount. I purchased a Samsung Galaxy Tab A 8.0 (model SM-T350) to run the same apps, using GPS only. I understand how to turn on/off the icons from the swipe-down menu, how to modify the location accuracy, and have tried the tablet in multiple locations without success. I was looking for more technical answers as to whether anyone has been able to get a model SM-T350 GPS to work while not on WiFi, perhaps adding a puck? I've tried everything I could find on Google, Samsung wasn't any help, so I decided to ask here, as many people here have figured out things like this. The images above are screen shots of Gaia GPS, with High Accuracy on, without WiFi, and with WiFi. I can't make any technical sense as to why I can't get the GPS to function correctly. If the SM-T350 won't work, I'd appreciate recommendations for tablets that do not need to be connected to WiFi, nor a wireless service provider.
Hopefully this made more sense, and thanks for the patience. I still love my old school maps, but there's nothing like knowing exactly where you are, down to a couple yards!
