In fact my first question is: Does LUMIA 900 have really GPS function?

Or say, is it possible Lumia 900 use GPS only but not A-GPS??? How to???

I have lumia 900 on my hand, but recently the GPS fix is not accurate at all. I've downloaded the latest software, also other GPS/Map software.

The situation is every first time I use the installed file, the GPS fix works well and guide very good.

But then from the 2nd time I use any one APP, it becomes not accurate at all.

The I guess maybe my operator's error, so I try to make my phone offline, in airplane mode.

Then open NOKIA DRIVE, then always be: looking for GPS.....about 30 mins, still failed

Then I use another APP, found, there is NO GPS SINGAL AT ALL, under OFFLINE MODE.

Then I have 2 following questions:

1. Is there GPS (but not A-GPS) in Lumia 900??? How to active GPS only to fix location but disable A-GPS??? Is it possible?? Frankly, if it's not possible, how can say Lumia 900 have GPS???? rediculous

2. Why it happens, I mean the not-accurate GPS fix.  And how to correct it??? Can't say I uninstall then re-install APP again every time, is it??

THANKS!!!!!
