We are unable to speculate on the release of any updates. Typically unlocked devices are some of the last devices to get major updates as the carriers send the software out to the devices once Samsung has sent out the approvals. You always have the option to try using Smart Switch to push the update or you can speak with your local uBreakiFix to see if they have the latest software available to push.
