are you on the border? I noticed that my weather app sometimes gives me my city and a city right next to me. I am literally on the border so I can understand, even changes when I'm in different parts of my house, lol.
As for maps, I've heard that it can find your location via cell phone towers or wifi. I've only used GPS signals when i use maps and it gives me my exactly location correctly everytime.
well i dont have the "use gps satellites" enabled, only the "use wireless networks" one enabled and it was working fine before, now it pretty much just thinks im in a different city lol even when i drive around its showing the little blue dot move in another city and not where im at lol
