Personal Information and Data 
Security
The use of some functions or third-party applications on your 
device could result in your personal information and data 
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 
SIM card, memory card, or stored in your device memory. 
If you change to a different device, be sure to move or 
delete any personal information on your old device.
•  
If you are worried about viruses when you receive 
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.
•  
If you use services such as Wi-Fi tether or Bluetooth, set 
passwords for these services to prevent unauthorized 
access. When these services are not in use, turn them off.
•  
Install or upgrade device security software and regularly 
scan for viruses.
