In general a GPS won't work indoors because the satellite signal is very weak and doesn't generally penetrate into buildings. None of my GPS units (a couple of Garmin GPS II+ handhelds, a Garmin GPS 35 'blind receiver', a Tomtom satnav and a Binatone B.350 satnav) will work indoors and I don't expect my newly acquired RedBox FLARM to do so either.
However, a phone can find out where it is, though at lower accuracy, as long as it has a signal and is running an application that can get the information from the network. That only works because the network knows which cell your phone is in and where its cell towers are. This is such low accuracy information that it would be useless to XCSoar and hence would be ignored even if the phone makes it available. > I am not sure if it has to have movement to work??? > A GPS system knows where it is if it can see three or more satellites and its height if it can see 5 or more. It can do this whether its stationary or moving. However, it has to be moving to know where North is.
