Help Galaxy note 4 setting menu background logo

[aqibanum]

HI all, I just got used galaxy note 4 n910U, basically phone was purchased from Vodafone but unlock for all carrier. Just wondering, I got a logo (picture attached) whenever I open setting option, wall paper, and even camera, "try me" Vodafone logo is displaying. Can someone guide me how can I get off this irritating logo.
Thanks.

Regards,
Aqib

Wow. Sorry I can't help but that's the 1st time I've seen anything like that. Does it ever disappear or is it always there? (if always, it looks to me like display burn-in, maybe from a store demo unit)
I'd return it If that's the case
