Nokia Lumia 820 - Keep your data secure on your phone

Your phone has a variety of security options to make sure no one else has access to the sensitive data you have stored on your phone. For example, you can set your phone to lock automatically, or you can even locate your phone if it gets lost (not available in all regions).
