Its an official samsung one so im going back and forth between the normal cover and the charging case.
Some googling seems to show that the wireless S View case definitely has its own nfc receiver built into it so im going to keep trying with that for now as I am having better luck with it =)
Edit: Trying it with the nfc sticker I get hits pretty much over the entire back of the phone whereas without it I only get near the known sweetspot =)
