Connection security

If the security indicator ( ) is displayed during a connection, the data transmission
between the device and the internet gateway or server is encrypted.
The security icon does not indicate that the data transmission between the gateway
and the server where the data is stored is secure.
Security certificates may be required for some services, such as banking services.
You are notified if the identity of the server is not authentic or if you do not have
the correct security certificate in your device. For more information, contact your
service provider.
Important: The existence of a certificate considerably reduces risks involved in
remote connections and software installation. To benefit from increased security,
certificates must be used correctly, and they must be correct, authentic, or trusted.
Certificates have a restricted lifetime. If they are expired or invalid, check that the
current date and time in your device are correct.
Before changing any certificate settings, you must trust the owner of the certificate
and that the certificate does belong to the listed owner.

Positioning (GPS)

You can use applications such as GPS data to calculate your location or measure
distances. These applications require a GPS connection.
