I use a cheap 7 inch Chinese generic WinCE GPS that I got for $2 new at a second hand store, because it was stuck in a reboot loop which I was able to fix.
Because smartphones are mostly just spying and brainwashing devices, I don't have a SIM card in them, keep them in airplane mode and use them only for watching pre-downloaded videos, but they do have a GPS program on them "just in case".
Seriously considering going back to paper maps as I tend to get "lost" more easily now without the GPS, which is concerning.
