No rep till now. Does anybody know if 9190 and 9195 NFC functionality is just the battery feature?
Could anybody try such battery in the 9192?

Thanks.

Does the 9190 have 4 pins at the battery connection? Or only 3?

9192 has only 3 pins at the battery and at the phone side.

Then having an NFC battery will not help. The fourth pin is to contact the NFC antenna within the battery
