Version I9300XXELK4 is now available to download and install, at your own risk we’ll add, bringing Android 4.1.2 Jelly Bean and new features to your handset.

One of the highlights of this Android update is the multi-window feature that we keep hearing it’s going to be soon available on Galaxy S3 smartphones as well, in addition to Galaxy Note phablets.

  • Android 4.1.2 – JZO54K
  • Multi-View (Multi Windows Multitasking, same as in Note II)
  • Page Buddy
  • Notification Panel (Notification Panel can now be customized)
  • Smart Rotation (Screen Display adjusts to your angle of sightings)
  • Continues Input in Samsung Keyboard (Like Swipe or Android 4.2 Keyboard)
  • Paper Artist App (Same as in Note II)
  • New Gallery App (Same as in Note II – This is AWESOME)
