Are you using stock Battery? Or have you done something with the battery when you flashed the new ROM?
Try to remove the battery and put it back in again and see if it changes anything.
FYI The battery have to be NFC compatible since its there the "chip" or whatnot for NFC is located.

Do a factory reset. Backup ur sdcard stuff first.

Have you tried pressing the little square in front on NFC? That's exactly how mine looks if I disable NFC, and with just a click it turns back on..

Removing the battery and placing it back again worked for me.
Thanks for the tip, i should have thought about following the first rule of IT - turning it on and off again
p.s.
While looking at the battery i saw that it has "Near Field Communication" written on it. so i guess its true that the battery makes the magic happen. a little disappointing, i though it was more sophisticated than just the battery. maybe the battery is just the antenna.

NFC Issue

I'm running on CM10 nightlies (up to the latest). I can't get my phone to do anything NFC related.
I have NFC enabled in settings, beam is on, and I installed Z-Device Test from the Play store and it tells me the NFC is indeed active.
I have a Nexus 7 and a Nexus 10 which I can use to beam (they beam fine to each other). I took my phone and ran it along the front and back of both the 7 and 10 and it does nothing.
I've searched but couldn't find anyone with a similar issue. I even installed NFC Enable script for JB - no dice.
Can anyone help me out? Am I missing something?
Edit: I should add that I have a Laza extended battery with NFC and I've reached out to them. I also stuck the stock battery back in just to see if it was the extended battery and still no luck.

Does it work on stock?

Nope.

Same here, no luck with Nexus 10.

running PA v2.55 for some time now and happened to notice this issue as well.
really wanna use this feature (particularly after seeing holiday TV spots) but just cast that silly notion aside, considering how much more mighty my phone is than everyone else's.
hope there's a keen solution :beer:

Bump?

[REQ] NFC Screen Off

Looking for a flashable zip that will allow NFC use even while the screen is locked and/or off.
Recently got some NFC tags to turn bluetooth on in my car, but its kind of defeating the purpose if I have to use my phone to enable it.
I'm on 4.2.1 currently using MMuzzy's ROM while I wait for a stable build of CM10.1
NVM, just switched to a ROM that supported this.

NFC won't turn on, uncheck himself immediately

Has someone else had a simelar problem with HTC One X? When I check the box on for NFC, it immediately uncheck itself. I had this problem since I updated to JB, already reverted to stock Jelly Bean still doesn't work. On ICS it worked fine, I have also reverted to stock ICS and ARHD ICS and there it also. So it's not broken, there's just somethingwrong with JB by me. But since JB it never had worked. I hope someone could help me. Because a friend of me bought a HTC One and now I would like to use NFC.

[Q] Working NFC while screen off

Is there any xposed module or modified NFC apk out there for the LG G3, which enables NFC when the screen is off?
I'd like to unlock my phone with a NFC tag without turning the screen on first.
I was searching google, reddit, xda but couldn't find anything for android 6
I'm running XenonHD if that matters.
Thanks
