This is on Android 11, latest Chrome (96.4664.104). I call navigator.geolocation.getCurrentPosition. If the accuracy is low I call it again. A similar geolocation object is returned, just with a new timestamp.

However if I start the Google Maps Android app between the first and the second call to navigator.geolocation.getCurrentPosition then I get a more accurate position in the second call.

Is there something I can do in JavaScript instead to get a more accurate position?

Here is the options used in the call to getCurrentPosition. The time between the calls is at least 2 seconds.

  const optPosition = {
    maximumAge: 1000,
    timeout: 1000,
    enableHighAccuracy: true,
  }
