Galaxy S5 :: GPS Not Found On Waze And Not Tracking On Google Maps

I purchased an Unlocked Samsung Galaxy S5 on Amazon in March to use with AT&T. Since I purchased the phone I've been having continued issues with the GPS specifically when using Google Maps and Waze for GPS directions. The location services works fine for every other app, including Swarm/Foursquare, Weather and Facebook...there are no issues finding my location for these applications.

When using Waze: I will always get the "No GPS. Showing approximate location." error every time I attempt to use the app.

When using Google Maps: The phone does not track along with my progress through the turn-by-turn navigation. The GPS will follow me along the route, but the application will not provide the turn-by-turn updates as I progress along the route (it will stay stuck on the first step of the trip throughout).

I've already attempted to clear data, clear cache and force stop the apps several times, I've used the GPS Status app to download GPS assistance data as well as using it to reset the GPS cache. The application is unable to find GPS location, no matter how long I leave it running and regardless of whether I'm sitting outdoors on a completely clear sky or indoors, there's no luck with the app.

This really starting to get on my nerves, and I'm considering just doing a factory reset of the phone in the hopes that doing so will reset the GPS as well (I'm assuming I must have done something along the way during the set-up when I first started up the phone).
