[Sprint Samsung Galaxy S III] nacron:
For some reason I can't get my phone to recognize the NFC tag when the screen is off or even in the lock screen. Only when I'm past the lock screen will the NFC tag recognize. The xposed framework was part of the ROM i'm using (M.O.A.R.) and I just installed the MoDaCo mod via the link. I checked off NFC on always and restarted several times but it still won't recognize when the screen is off.

[EDIT]

Got it to work using this xposed module instead of the MoDaCo one for always on NFC.

Also having issues of lock coming back on after doing any action post unlock via NFC. I think it's a hack Samsung put together for the latest firmware upgrade after the whole problem with the bypassing the lockscreen by going through the emergency screen. The op wouldn't have this issue as he's not using a TW rom. I wonder if there is a way to have it input the key instead of bypassing the key.

Overcame this issue by using the secure settings to reset the pin to nothing when unlocking via NFC and enable the pin when the screen goes off. This method even prevents the phone from locking during a call. I have a new issue of the swipe screen coming back right after NFC unlock. I'll post my findings a little later. It's not the most elegant of fixes but it prevents the lock screen from coming up when pressing the home button. I also removed all the waits and made lights and keyboard on for 5 seconds, makes unlocking faster.

The action for password/pin reset in Secure Settings is in All Actions > Dev Admin Actions > Password/Pin. You just select disabled when unlocking and it removes your existing pin and when you select enabled for lock, it prompts you to enter your pin twice in the settings. Not sure how secure this is or where it stores your password/pin. The only problem with this method is that you'll have to change the password/pin in secure settings if you decide to change your password/pin in the android settings or you'll end up with 2 different passwords/pins

Not sure if this works if you have pattern unlock. Haven't had time to test that.

So this is how my unlock task looks like:

1. Stop task lock

2. Secure Settings > configuration > Screen and keyboard lights on for 5 seconds

3. Secure Settings > configuration > clear password

4. Secure Settings > configuration > Keyguard disabled

and my lock is simply

1. Secure Settings > sonfiguration > Set Pin

and my profile is

Display Off > Lock

[EDIT3]

Figured out why it was presenting the swipe lock screen when doing a quick NFC unlock removal . I'm using the hacked version of AnyTAG NFC Launcher, instead of the NFC Tag Task Launcher, that detects NFC Tag removal as well as placement. Thought this app would be more extensible in the future. The only problem with this is that it will keep insisting on launching on NFC Tag removal if you don't set something so I just set the task to do nothing and that was locking the swipe screen again. I just set it to the same task as unlock and it doesn't pull up the swipe screen anymore.

Also, the battery replacements from Sprint suck. It's a generic sprint branded battery that DOES NOT have an NFC antenna in it. Picked up the replacement along with tectiles yesterday and couldn't figure out for the longest time why this unlock thing wasn't working. Their battery part number is BSML71021L. Gotta call them up to see if they can give me back my old battery or give me a real samsung replacement.

After trying to get this to work consistently, I've disabled it. I can get tasker to remove/reenable the pin consistently but only sometimes will it clear the lockscreen automatically.
