Yet the rest of the Galaxy S4 I9500 users around the world did not saw the arrival of Lollipop update on each respective countries. But noting that the 5.0.1 Lollipop seems like it still under in a constant improvements so we might expect more Lollipop update to be roll out soon. The first 5.0.1 Lollipop update was found with some minor issues, so hope this one will resolve it and could be a much more stable build.

  • TURN OFF the Reactivation Lock – This is only needed if you already turned-it-ON, from which you cannot modify the system when it’s turned-ON. Go to Settings>>Security>>Reactivation Lock and then uncheck the Turn Reactivation lock on.
