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.

• Be sure to obtain third-party applications from a
legitimate source. Downloaded third-party applications
should be scanned for viruses.
• Install security software or patches released by Huawei or
third-party application providers.
• Some applications require and transmit location
information. As a result, a third-party may be able to
share your location information.
• Your device may provide detection and diagnostic
information to third-party application providers. Third
party vendors use this information to improve their
products and services.

Safety information
This section contains important information about the
operation of your device. It also contains information about
how to use the device safely. Read this information carefully
before using your device.

with other electronic devices.
Interference with medical equipment
• Follow rules and regulations set forth by hospitals and
health care facilities. Do not use your device where
prohibited.
• Some wireless devices may affect the performance of
hearing aids or pacemakers. Consult your service
provider for more information.
• Pacemaker manufacturers recommend that a minimum
distance of 15 cm be maintained between a device and a

pacemaker. If using a pacemaker, hold the device on the
side opposite the pacemaker and do not carry the device
in your front pocket.
Protecting your hearing when using a headset
• To prevent possible hearing damage, do not
listen at high volume levels for long periods.

a safe and comfortable level.
• Exposure to high volumes while driving may cause
distraction and increase your risk of an accident.
Areas with flammables and explosives
• Do not use the device where flammables or explosives
are stored (in a gas station, oil depot, or chemical plant,
for example). Using your device in these environments
increases the risk of explosion or fire. In addition, follow
