Unfortunately this can be the issue when a person imports a phone to their country that was meant to be used in another.
XEU csc code is an Samsung phone that's unlocked to all networks but not supplied directly by Samsung.
The ones supplied by Samsung are BTU.
Updates are sent out dependant on country of origin and the phones build and serial number.
Samsung are correct to say keep checking the software update section in the phone.
You could if you wish pop over to the xdadevelopers site to look at firmware options which may / may not yield help.
A person doing this does so at their own sole responsibility knowing that a phone can be put Into an unusable state and possible manufacturing warranty being voided.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
