After discussion with Samsung they have agreed to provide me with 2 years’ warranty on the phone. I’m rather impressed (and pleasantly surprised) that they have done so. If they hadn't then I would simply have sent it back for a refund and bought from an authorised Samsung outlet instead.
I have had a few Samsung phones and they have never come in a cellophane wrapper, they have come in their official box with official Samsung break seals. If the break seals have been broken then you know the box has been opened and you wouldn't accept the phone as being new.
