How can I update my Nokia Lumia with Windows Phone 8?
Software updates from Nokia and Microsoft are safe to install, and your settings, apps, photos, and text messages remain safe and sound.
Software updates are free of charge, but to download the update, you need an internet connection, and data transmission costs may apply. For more info on the possible costs, contact your network service provider. To keep data costs down, we recommend that you use a Wi-Fi connection.
Your phone notifies you when an update is available for you.
Step 1. To view and to install the updates, just tap the notification message, and follow the instructions shown on your phone. You can install the update immediately, or postpone the update to a more convenient time.
Step 2. The update should take around 15-30 minutes, but it could take up to 60 minutes. You will not be able to use your phone during the update installation. Don’t worry if your phone restarts several times during the process, that’s completely normal.
Step 3. Update success! Now you can use your phone, and enjoy the new features and enhanced experience.
Tip: It is recommended that you use a Wi-Fi connection for the update.
