The product complies with the specification and is a Samsung original. But watch out for the owners of Galaxy S2 Cityzi (I9100P) comes with NFC chip (this Orange day only) like mine. Token shell provided lugs which are clipped but which are shorter than the pins of the original hull. Finally, the hull is sometimes difficult to correctly clipped on the phone, it is then necessary to emphasize, but the result is not perfect, part of the shell not clipping perfectly (left side in the middle for 2 pins). For testing against a Galaxy S2 I9100 (not NFC) poses no problem because the original shell has the same type of pin. Hopefully Samsung will remedy the problem.
