You could order the Samsung phone from another Amazon store, you might even be able to skip the OTP requirement by doing so, so you could go for the easy DNA method
I know this since I ordered from a different country's AMZ store with my usual account and it didn't require an OTP on delivery, while the same item from my own country did
I guess it's somehow tied to the fact that international shipping can't carry the OTP requirement somehow? Not sure, but it's worth a try, just put the item in the cart on the .de or .fr store and see for yourself

You're absolutely right! I just checked on Amazon.fr and it doesn't say anything about OTP on the checkout!
That being said they only have the 128GB version on stock right now, so I think I'm gonna wait until they have at least the 256GB one.

Speaking about the phone, I did some research and from what I've seen in unboxing videos, the box completely opaque, and only held by two regular stickers on either side. So I think it could also be suitable for the sealed box method.
