It takes GPS a few minutes when you first use it to get a fix on the satellites, but if you use it regularly, it won't take so long and having it get a satellite fix in the camera mode doesn't mean it won't take a few minutes to find a fix in different software applications.
When getting a first satellite fix make sure your device has a clear view of the sky....taking it outside might speed things up abit. After that, my device finds satellites inside without much trouble.
Your device can find a fix with or without using the the Quick GPS app. The difference is that using Quick GPS downloads satellite information to the device that speeds up the process to get a new fix. But I found the Quick GPS on my hw6925 got messed up from time to time, so, to me it was more trouble than it was worth. I don't use Quick GPS at all and don't really notice that it takes that much longer to get a satellite fix.
