My question is aGPS should be using data transfers and triangulation to help determine location, right? If I disable GPS on my device, will aGPS kick in? I doubt it'll work, but I'm willing to play around with it. Is there a way to know "which GPS" is trying to function and determine location?
Tell me if I'm getting this complety wrong!
If your carrier is doing aGPS properly, then you can get GPS, assuming you have cellular signal. If your building is blocking your cell signal, theres pretty much a 0% chance that you will get TRUE GPS either.
That being said, HTC devices don't seem to REALLY do Sprint aGPS. On my M1, which has a similar hybrid aGPS chip, I could get locks in the bottom floors of hotels, in thick concrete buildings, and other crazy places, and it never took longer than 2 seconds to get a lock.
With the Vogue, it takes anywhere from 5 seconds to 20, assuming you are outside, or in a friendly building--near a window/etc..
I miss the true aGPS
I sat my phone next to my co-worker's Instinct, in one of our server rooms, and both opened up Sprint Navigation. His locked in less than one second, and mine never locked--ever.
