Just like a computer, your phone uses software to run. By making sure you always have the latest version of this software, you get:
- performance improvements to things like battery life and applications
- new and improved functions
- the latest versions of Nokia applications and services
- bug fixes
With Windows Phone 8, your Lumia automatically checks for updates on a weekly basis. To change the settings, or manually check for updates, just tap Settings > Phone Update.
If you have Lumia 505, 510, 610, 710, 800 or 900, set your phone to notify you about available updates, select Settings > phone update > Notify me when new updates are found.
