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.
Before starting the update, connect a charger or make sure the device battery has enough
power.
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.
By default, your phone automatically downloads available updates whenever the data
connection settings allow it. When your phone notifies you that an update is available, just
follow the instructions shown on your phone. If your phone is short on memory, you may need
to move your apps, photos, and other stuff to the memory card. The memory card is not
supported by all phones. For availability, go to www.microsoft.com/mobile/support/
wpfeatures.
Tip: To move your apps to the memory card, tap Storage > This Device > Apps &
games, tap the app you want to move, and tap Move.
Tip: By default, your phone updates your apps and other components automatically
when you’re connected to a WiFi network.
After the update, check the Lumia Help+Tips app or support pages for your new user guide.
