What's made you think it may be refurbished @Tom2018
May I ask > Where did you buy it from ?
If you use Samsung Chat or if you have one pop into a Samsung Experience Store and they can check via the phones serial number on its status.
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
