I found that sometimes waze will prevent a GPS fix from occurring. Thus, when I open waze and it cannot get a fix, if I then open another app that tries to get GPS data (e.g. Google maps or GPS status) those apps can't get a fix either. If I then reboot and open one of those other apps first, the GPS gets a fix, if I then open waze while the GPS is providing good data, waze works fine.
