The only Android "device" I have is not a phone but instead a tablet
...8" Display (2048 x 1536) with Corning® Gorilla® Glass3 ...
Intel Atom Super Quad-Core, 64bit, 2.3GHz
4G RAM, 64G Onboard Storage
8M/5M Dual Camera; 1 x microSD Card slot, support up to 128GB SDHC
Android 5.0 Lollipop ...
This very capable tablet was way less pricey than my iPhone (and the Moto Turbo 2 I tried to like) and the GPS receiver is totally independent of other systems. I bought this for a specific ongoing project, but as long as it's available I decided to load it up -- apps are cheap enough.
Point is, why put up with a small cell-phone display when you can have one a little bigger that is much more capable -- the lines of text are longer and maps cover more area. Survival doesn't mean you need to suffer with a tiny display.
Just sayin'
