Not received One UI 6.0 in my US variant S23 Ultra.

Not received One Ui 6.0 in my S23 ultra in Nigeria. It's the US variant, but I got it brand new. I already received this update in my S21 ultra since January, but my S23 ultra isn't getting this update and it's April 8th, 2024. Have tried smart switch, but still nothing yet. 

It's still stock in September  1st security patch.

Not likely it will be updated, all considering. With Odin, possibly

My S21 ultra was US variant too. I ship from the US since I find it's more expensive in my country.

That's the problem, you shipped it from the States to a different region Nigeria any updates would have to be released from the states. This is the risk of obtaining a device from a different country you are based in.

You could try using your device behind a VPN linked to the US to see if that will allow the update but other than that, as your device is "out of region" you may be struggling here.

I know you said the S21 device was from the US but security is being upgraded all the time.

Maybe your phone is fake

I've been using Samsung phones since S9, you think I wouldn't know if I got a fake S23 ultra? Not experienced this issue before until S23 ultra. 

Knox security won't work, Smart switch wouldn't detect it if it was a fake and my Samsung account and data wouldn't move to the new device from the old one.

Tried that already,but it didn't work. Tried changing my CSC from OYN_XAA to something else using SAMFR and it didn't work either.

General rule of thumb (I believe but would happily be corrected) is that a device needs to be connected in the Region it is designed for and a couple of calls made. After that it should update wherever you are.
