This update as I said is only released via OTA and we have not seen it on Kies and weights around 82MB, its not a full packaged since the size were just too small but it has some tweaks on it.

For those rooted devices and can't get this update, you can manually install using CWM, a rootkeeper so that you will not lose root.Just follow this guide here to preserve root of your Galaxy S3 after the update.


  1. phone will not connect with mac through kies and android file transfer also i seen that pc wont either

  2. Has anyone else noticed a LARGE drop in battery life since the LH9 OTA upgrade?

    Suddenly Cell Standby is using 26% of my battery!
