The blue dot shows you where you are on the map. When Google Maps isn’t sure about your location, you’ll see a light blue circle around the blue dot. You might be anywhere within the light blue circle. The smaller the circle, the more certain the app is about your location.

What does the blue arrow location icon mean on iPhone? Apple previously used a black and white combination of two location arrows in the status bar to denote location access on your device. These arrows would let you know when your location is being accessed by an app in the background.
