Nokia Lumia 820 - Update your phone software

No computer needed – update your phone software wirelessly for new features and improved performance.

Before starting the update, make sure your phone has enough battery power.

Using services or downloading content may cause the transfer of large amounts of data, which may result in data costs.

  1. By default, your phone automatically downloads available updates whenever the data connection settings, for example roaming, allow it. When your phone notifies you that an update is available, just follow the instructions shown on your phone.

    Tip: Check Store for app updates.

  1. If you want to keep tight control of your data costs while roaming, you can switch off automatic update downloading. On the start screen, swipe left, tap settings iconSettings > phone update, and clear the Automatically download updates if my data settings allow it check box.
