Software and security patches are sent out in waves dependant on phone model, region your in , phone serial and build number.
Phone's that have been supplied directly by a network known as a branded phone can sometimes have their own update schedule as some networks want to test updates before they hit the phone's.
You can also check on sammobile.com for updates.
I wish you all the best.
