When the device receives enough data from the
satellites for GPS to calculate your location, the bar
turns green. The more green bars, the more reliable the
location calculation.
Initially, your device must receive signals from at least
four satellites to calculate your location. After the initial
calculation, signals from three satellites may be
enough.
The data transfer indicator
shows the
internet connection used, and the amount of data
transferred since the application started.
