Why is my Samsung Galaxy GPS not active, it says ‘searching for GPS?’

The GPS is ACTIVE but it requires satellite coverage. It connects to various satellite signals in order for the positioning system to show your position. It checks for the various satellite signals that are available and connects to them as per the strength of those signals. So higher is the strength of those signals and the better the availability and the connectivity, the better is the positioning accuracy of your Global Positioning System. The quickness of the GPS connection and the accuracy of the positioning due to GPS is better in open areas where there are less trees or near your window when you are inside the house as the signal strength will be better.
