GPS Chip and GPS Service on Android Phones Whether I use Google's location services or similar services provided by some third-party software, do I still need to manually enable anything by selecting one of the settings options, as shown below?

Settings &gt; Location and Security &gt; My location (Option1) Use wireless networks (Option2) Use GPS satellites

Since there are many GPS software programs available these days, what is the role of the onboard GPS chip on an Android phone?

Thanks.
The GPS applications will not work accurately unless you enable the on board GPS so all you have to do is simply check "Use GPS Satellites".
