How to change android version Jellybean 4.2.2 to the newest update? I have a Samsung Galaxy S4 Zoom and my current Android version is Jelly Bean 4.2.2. I kept on trying to update the version but it kept on saying that my phone has installed the newest update. How can I change my Android version to the Lollipop one?
