GPS fix error in AirCasting App

When you open the map in the AirCasting app, if an error pops up that reads “Without a GPS fix you can't map your session or contribute it to the CrowdMap.”, your phone cannot get a strong global positioning system (GPS) signal. This is most likely because you are indoors.

While connected to Wi-Fi, try stepping outside or getting closer to a window to make it easier for the phone to get a GPS signal.  Note that without a GPS signal, the phone cannot detect your location and your sampling data cannot be uploaded to the map.
