just bought a i9195 and right away i've flashed vikinger kernel.
although i didn't tested it, I'm pretty sure on the official rom i had nfc enabled but I can't turn it on anymore.
tried on a bunch of roms, stock an vikinger kernel but no luck. nfc is always disabled and when i try to enable it the button moves to "I" for a couple of seconds but it goes back to "O", doesn't turn green.
the only rom i could enable nfc is cm11, so no hw problem..
knox is 0x1 but i don't think this has to do anything with it..
can you please confirm nfc is working on specific roms? (jm7, knox 0x1)
any ideas?

Deodexed stock MK3 + arco's kernel -> NFC works like a charm!

Same problem. Also on my s4mini NFC doesn't turn on. When bought it was OK. I'm on stock ROM with arco's kernel (but i tried also with kernel stock and it's the same). Last proof at this point is reflash firmware with odin

edit. still no NFC also after flash kernel with odin

Don't know what happend, but I just flashed stock rom mh3 with Odin. NFC still not working, don't know what else to do, because going back to stock is the hardest reset I can do, or not?

if NFC breaking depends on cwm, cyano, kernel mods, ecc... I thing that flashing stock kernel with odin everything would have to return to work but it not happens. maybe, because the chip is in the battery could be a battery problem (even if an user with same nfc problem says that under cm11 NFC works, so it isn't a hardware problem). anyway sorry for OT.

I am moving the discussion back to this thread.
Just flashed cm11 and nfc is working, so it's not a hardware issue. But still don't get it, why it's not working on stock rom....

thanks for moving my post in right place...
it's good to know that it's not a hardware issue. maybe a samsung firmware update (i hope with android 4.3 ) could fix the problem....
