Please note that Ubuntu is only relying on the currently connected cell
to determine an estimate of the position. That estimate is quite
unreliable unfortunately, and it might very well be the that estimated
values are discarded internally for that very reason.

I will follow up with a confirmation of this hypothesis.

Please also note that applications (on purpose) have no say in whether
they receive a network- or satellite-based position. They specify a
required accuracy and the infrastructure satisfies the request if
possible.

Title:
  Ubuntu Phone is not getting a mobile network cell triangulation
  position

Status in Canonical System Image:
  Confirmed
Status in location-service package in Ubuntu:
  Confirmed

Bug description:
  Hi!

  I think that the mobile network cell triangulation position is not
  working in Ubuntu Phone OS.

  The position should be really fast (~1 - 5") and I'm thinking that
  Ubuntu Phone is waiting for a real GPS position every time.

  A good test could be this:
  - Go to a room, way out of a sky to avoid a real GPS signal.
  - Set WiFi service OFF.
  - Set GPS service ON.
  - Set data connection ON.
  - Go to this website via webbrowser-app: http://leafletjs.com/examples/mobile-example.html The website will ask you to allow access to the current location.
  - Make sure to not have a GPS position cached.

  In a PC or *any* Android you'll see your position immediately.
  Bug: In Ubuntu Phone an error will appears. This error is because the geoposition (https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation) is not working with the cell triangulation network data.

  You can try a lot of apps like Google Maps, OSMTouch, HERE map, uNAV... and a fast position from data connection is not happening, unless you be with a WIFI connection.
  If you try Google Maps in Android, the position will be really fast just with data connection.

  Thanks in advance!
