[Q] Working NFC while screen off - G3 Q&A, Help & Troubleshooting

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

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:

[Q] NFC while screen is locked / off with stock 4.2.1

Hey,
i have a Galaxy Nexus with Stock 4.2.1. I would like to use NFC when either the screen is looked or the display is turned off.
To do so I found:
http://forum.xda-developers.com/showthread.php?t=1709586
But the NFC replacement is not starting on my Phone. Also the developer wrote at the first Thread there might be some Problems with stock 4.2.1.
Does anyone have another NFC replacement working on Stock 4.2.1?
Thanks

[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.

Smartwatch 3 - NFC uses

Hi,
Just wondering if anybody has tested the NFC functionality? I am currently using the Smartband - and I use the NFC on the Core with Xposed Framework to unlock my phone (Xperia Z1). Aside from dealing with the annoyance of having Lifeblog constantly launching upon unlocking - I find it quite useful without having to enter a PIN every time.
Not many details on the location of the NFC antennas on the SW3. Wondering if I can truly replace the Smartband with the SW3.
There is smart unlock feature in lollipop so it will not ask for pin if smart watch connected, I believe you can achieve similar with xposed or 3rd party apps on previous versions of android
NFC works
If you got NFC on your phone turned on the phone recognizes the watch by bumping and opens the android wear app.

If the watch is off, nfc contact also turns it on.
I was testing SW3 NFC with newly purchased Sony SBH-60 headphones. No luck - nothing activates. The headphones worked fine once manually paired, but in my opinion NFC does not work, most likely is not supported by Android Wear yet. Which would be another big disappointment - no LifeLog app on the watch, no sleep tracking with use of Watch, no Walkman app, now no NFC support.

hey I'm about to buy those headphones, but I can't find any reviews about it, I don't know if you could tell me if they are any good, and if I can pair them with my nexus 5.
Thanks in advance.

So far, so good. Everything works as advertised and nice sound, overall yet I'm not an audiophile to comment on a lot. I think you should not worry about pairing with Nexus 5, but I can't tell for sure, no N5 around to test

Yes, this is the only feature that works. Not really useful.
Thank you BartManx, I'm also not an audiophile so I guess it'll be good to me too.
Until Android Wear starts supporting NFC, it's hard to test the full capabilities of NFC on the SW3. As others have reported, right now it just opens the Android Wear app on the phone.
Galaxy Note 4
I can't sync with Galaxy note 4. Any solution ?
According to the owners manual the NFC antennae is in the centre of the screen. Which makes sense so it can be used while on your wrist.

Thanks I guess reading owner manuals is a good thing
If you don't have Lollipop, but you have a rooted phone, NFC and Bluetooth can be awesome.
I hate using a pass code. I like waking up my phone and going right to what I want to do. However, if I ever leave my phone unattended, it would be nice to know that someone can't just get into it and start messing with things. So, I have a rooted LG G2 running Xposed. There is a module called: "No Lock Home"
In a nutshell, after you enter you Bluetooth address of the watch into the module, if you are wearing your watch and you walk away from your phone far enough to break the NFC/Bluetooth connection, the phone goes into lock mode (meaning you need a pass code or pattern or whatever you set up); once you come back into range of the phone, the pass code/pattern lock goes away and you're free from having to take the extra 3 seconds to "unlock" your phone.
Technology is the bees knees!!
There is an app called Skiplock which I believe is made by someone on XDA which does the same thing but without the need for root. You can use BT or Wifi for keeping the phone unlocked.
I'm not sure if my sw3 doesn't have (dont work maybe?) nfc or my nexus 5's nfc isn't working. Anybody could show me what happen when the sw3 is close to a smartphone?
EDIT: found it https://youtu.be/4YStUt_RPKs?t=5m7s
So or my nexus 5 nfc is fkd up or my sw3's nfc is fkd up lol
EDIT2: Ok solved. The replacement part I got for my nexus 5 was broken. I got use the nfc+wireless recharging combo from my old (original) back cover.

THANK YOU so much for this. This will help me - I hate using the knock code on my rooted LG G2 when I'm driving. Bob-on.

NFC While screen off Marshmallow

This has been discussed before, but hasn't been talked about for Marshmallow. Plus everything about this seems abandoned. It is quite unfortunate. It is very convenient to be able unlock my phone just by putting it over a nfc tag. I was able to do this on kitkat with an xposed module, but since development stopped on that module, it hasn't been possible. The module allowed me to scan an nfc tag while the screen was off and Tasker would dismiss the passcode and lockscreen. It would unlock directly to the home screen. If nobody else has any idea on how to do this, I guess I can try learning xposed and continue development on that module, but it definitely seems over my head since I've never made an xposed module before.
