Check satellite signal status
To check how many satellites your device has found, and whether your device is receiving satellite signals, press , and select Tools > Connectivity > GPS data > Position > Options > Satellite status. Or, in the Maps application, select Options > Map view > GPS info.
If your device has found satellites, a bar for each satellite is shown in the satellite info view. The longer the bar, the stronger the satellite signal. When your device
has received enough data from the satellite signal to calculate the coordinates of your location, the bar turns black.
Initially your device must receive signals from at least four satellites to be able to calculate the coordinates of your location. When the initial
calculation has been made, it may be possible to continue calculating the coordinates of your location with three satellites. However, the accuracy is generally better when more satellites are found.
Position requests
