Sorry but your conclusions don't hold much water. Older versions of Google maps work fine, as does the latest version.
GPS takes time to lock on, especially if it is the first time or your position has shifted considerably since the last lock or if it has been a long time since it last located you.
The device must first download the ephemeris tables so it knows which satellites to look for and where to look, since they are in elliptical not geo orbits. Then it has to locate you precisely, generally within 10 meters. I have seen it take upwards of 20 minutes to get a good fix, but it is usually within 5 or so.
You need to be outside with a clear view of the sky, at least for the initial fix. It really helps to start GoogleMaps since that app uses cell tower triangulation to set your position initially (within 2500 meters or so) and allows the GPS to lock on quicker.
Probably more than you wanted to know.
