Hi @Masser know it has been quite a wait but the patches come out in batches and depends on your device , whilst unlocked non Branded devices tend to be the first in line.
Can also check Smart Switch as possibly you may be able to receive it sooner via that method.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
