One of the greatest points of owning an Android handset is running custom ROMs. But there are a few who prefer official ROMs over anything else because of performance and many other issues apparently. If you are one of those then you might want to update to the Official Jelly Bean XXLPZ on Galaxy S Advance I9070 which is available Over-the-Air. If you haven’t received the update, you can follow this tutorial in order to update your phone no matter what region you are in. Remember that this tutorial will only work for Galaxy S Advance.
