About phone software updates 
Stay in step with the beat – update your phone software to get new 
and enhanced features 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.
Before starting the update, connect a charger or make sure the 
device battery has enough power.
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.
