Update your phone software
Stay in step with the beat – update your phone software and apps wirelessly to get new and enhanced
features for your phone. Updating the software may also improve your phone performance.
Make sure that the device battery has enough power, or connect the charger before starting the
update.
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.
