If your phone notifies you about an update, follow the instructions to download and install it.
Your phone downloads updates over your Wi-Fi connection (if available) or mobile network. We recommend that you
download updates over a Wi-Fi connection. Remember, these updates can be quite large and may not be available in
all countries. If the mobile network updates are not available in your country, update using a computer.
