About phone software and application updates
With phone software updates and application updates, you can get new features and
enhanced functions for your phone. Updating the software may also improve your
phone performance.
It is recommended that you back up your personal data before updating your phone
software.
Warning:
If you install a software update, you cannot use the device, even to make emergency
calls, until the installation is completed and the device is restarted.
Using services or downloading content may cause transfer of large amounts of data,
which may result in data traffic costs.
Make sure that the device battery has enough power, or connect the charger before
starting the update.
After the update, the instructions in the user guide may no longer be up to date. You
may find the updated user guide at www.nokia.com/support.
