Could it be related to NFC chip location ? Maybe you are used to it's position on 1+6.
Mine works rather fine (using with NFC tags though as Google pay not yet available in my country/bank combo) .
You are most likely right. I'd still test in knowing the NFC position, just to be on the safe side.
I had troubles picking up my WiFi SSiD + pass using NFC tag + his Huawei p smart or something.
I looked up the position on the web, and placed it more accurately, only then it picked it up.
However, I do agree that this shouldn't be the norm, what would be the point then.
