NFC inoperative

NFC battery does not work, and self-adhesive coating that surrounds it has a fold, which to me seriously calls into question the authenticity of the battery yet sold as an original Samsung battery (supplied with a sticker of authenticity but no box).

I am even more surprised that I chose Amazon rather than a third-party seller to avoid such problems. Order directly from Amazon do not put away from such practices.

I asked for a replacement to get to the bottom, and the 2nd copy had the same defects. I am not surprised by the comments indicating a rapidly deteriorating autonomy is classic with counterfeit batteries.
