Thanks for your inquiry. Once available, updates are released to Carriers and thereafter, it is at the Carriers discretion to release the update to customers. Since updates are released by Carriers in waves, we’re unable to determine when your device will receive an update. We appreciate your loyalty.
When you purchase the phone and you own the phone out right. I don't think the carrier should have any say so whether you receive updates or not nor what updates you can have. I think when you purchase a phone like a Samsung phone. Samsung themselves should be sending the updates only.
