Security
The use of some functions or third-party applications on your

being lost or becoming accessible to others. Several
measures are recommended to help you protect personal
and confidential information.
•
Place your device in a safe area to prevent it from
unauthorized use.
•
Set your device screen to lock and create a password or
unlock pattern to open it.
•
Periodically back up personal information kept on your
USIM/SIM card, memory card, or stored in your device

messages or emails from a stranger, you can delete them
without opening them.

If you use your device to browse the Internet, avoid
websites that might pose a security risk to avoid theft of
your personal information.
