Just swipe down from the top, and you can easily turn the GPS location on and off. My office is in a hole, so my legit reason is to preserve the battery. My Black Helicopter self usually leaves it off until needed, and yes, I know they can triangulate the towers.....Yup, went through app by app and did that. Was odd to see which ones had mic permission as default and which didn't. I uninstalled and disabled a lot. Unfortunately had to leave location on for some things. I use maps a lot for work travel.
