Updating your phone
Update your phone's system to the latest version to enhance performance.
• Using unauthorized third-party software to update your phone may render your
phone unusable or put your personal information at risk. Always update through
your phone's online update feature or download official update packages from
Huawei's official website.
• Your personal data may be erased during a system update. Ensure that you back up
important data before updating your phone.
• When updating, ensure that your phone has at least 20% battery power remaining.
• After updating, you may find that some third-party applications are incompatible
with your system, such as Internet banking applications and games. This is
because it takes a while for third-party application developers to release updates
for new Android releases. Please wait until a new version of the application is
released.
