Samsung Galaxy S3 i9300 has received another firmware update which is Android 4.3 XXUGNA5 with some minor improvements. I know many of you are still thinking of Android KitKat but who knows Samsung is going to release it for the Galaxy S3 users, for now you still have to play with the Android Jelly Bean. The update was initially released in Switzerland, and so far other regions has still not received the latest update, so I thought to post a tutorial on how to download and flash the latest firmware using Odin.
