lifetime. If "Expired certificate" or "Certificate not valid yet" is shown, even if the
certificate should be valid, check that the current date and time in your device are
correct.
Before changing any certificate settings, you must make sure that you really trust the
owner of the certificate and that the certificate really belongs to the listed owner.

Positioning with your device

You can use applications such as GPS data to determine your location, or measure
distances and coordinates. These applications require a GPS connection.
Your device does not have an internal GPS antenna. To use applications that require a
GPS connection, use a compatible GPS receiver (accessory sold separately). Use Bluetooth
connectivity to connect to the GPS receiver.
You can also use network-based positioning with your device.

Network positioning

You can use the mobile network to determine your current location, even indoors. This
is faster but less accurate than with GPS, and you cannot use the location as a starting
point for navigation.
To use the mobile network for positioning, select the network-based positioning
method from the device settings.

About GPS

To use GPS, you need a compatible GPS receiver. Use Bluetooth connectivity to connect
to the GPS receiver. To start using a compatible GPS receiver with Bluetooth connectivity,
select the Bluetooth application.
The coordinates in the GPS are expressed in the degrees and decimal degrees format
using the international WGS-84 coordinate system. The availability of the coordinates
may vary by region.
The Global Positioning System (GPS) is operated by the government of the United States,
which is solely responsible for its accuracy and maintenance. The accuracy of location
data can be affected by adjustments to GPS satellites made by the United States
government and is subject to change with the United States Department of Defense civil
GPS policy and the Federal Radionavigation Plan. Accuracy can also be affected by poor
satellite geometry. Availability and quality of GPS signals may be affected by your
location, buildings, natural obstacles and weather conditions. GPS signals may not be
available inside buildings or underground and may be impaired by materials such as
concrete and metal.
