My SG2 has problem locating my position when I'm at indoor. I noted that while I'm at indoor, it is normal that we can not get GPS signal. And it's where the A-GPS kicks in, locating through cell phone tower. So I did a test by disabling the "Use GPS satelites" and keep "Use wireless network" on. As expected, my phone failed to location my position. I seems odd to me, since I'm able to location my position in the indoor with an iPhone even though it might be a street off, but at least it can location my rough location. Is the A-GPS in my SG2 not working? Or is there any tweak that I have to make? Thanks in advance.
