I have resorted to me, as I have removed the black plastic strip at the rear end. This is fastened by a black tape. After removing the residual glue I could use him, but he is now a little loose. The metal surface which came to light after the plastic and tape, reminds me of the ground ("minus-pole") of cheap batteries, not very reassuring.
The first impression in use:
+ Battery capacity excellent, slightly better than the original
- NFC works, the connection is, however, considerably worse than the original battery.
