If your device cannot find the satellite signal, consider the following:
If you are indoors, go outdoors to receive a better signal.
If you are outdoors, move to a more open space.
Ensure that your hand does not cover the GPS antenna of your device.
If the weather conditions are bad, the signal strength may be affected.
Some vehicles have tinted (athermic) windows, which may block the satellite signals.
Check satellite signal status
To check how many satellites your device has found, and whether your device is receiving satellite signals, select Menu > Applications > Location > GPS data and Options > Satellite status.
If your device has found satellites, a bar for each satellite is displayed in the satellite information view. The longer the bar, the stronger the satellite signal is. When your device has received enough data from the satellite signal to calculate the coordinates of your location, the bar color changes.
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.
