I modified the Nfc.apk of different bases and ROMs to offer you the ability to use the NFC chip of your Samsung Galaxy SII Skyrocket not only while you are active but also while the screen is off and/or while the lockscreen is shown.

You have three options when to use NFC:
  • screen off
  • lock screen
  • unlocked


USAGE
  1. Rename the Attachment to Nfc.apk
  2. Backup your /system/app/Nfc.apk and Nfc.odex (if existing)
  3. Delete /system/app/Nfc.odex (if existing)
  4. Replace the original in /system/app - to keep permission use adb:
    • adb remount
    • adb push Nfc.apk /system/app
  5. Reboot phone (adb reboot)
  6. Disable NFC
  7. Enable NFC

The compatibility depends on the framework/base. If your ROM has the same specifications like one existing you can use the posted.
If none of the version work (test it!) make an Feature Request

Re: [MOD] NFC on screenoff and lockscreen - SGSII Skyrocket

Thanks, works perfectly. I wonder if there is significantly more battery usage as a result of keeping NFC polling on during screen off.

Re: [MOD] NFC on screenoff and lockscreen - SGSII Skyrocket

Is there any chance you could make this embryo 6.3?

This is a mod i could really use.

Use any root explorer, copy the apk and paste it in /system/app and then long press on the file and fix permissions so that the permissions look similar to the other apks' in /system/app which is r w - r - - r - -

Okay, will try that. Thanks!

EDIT:
Doing so disabled NFC functionality altogether! I copied and pasted the screen off/lockscreen/screen on one and renamed to Nfc.apk and set permissions to rw- r-- r-- and NFC is gone. So I reverted to the backup of the original.

EDIT 2:
Oh, probably because I'm on Android 4.1.2 :( I guess I need to flash CM 4.2

Hey I'm having NFC wakelock issue and an issue changing permissions. Whenever I attempt to change permissions I got an error saying that the file system might be restricting it.

I'm running Beanstalk ROM latest version. I've used 2 different root explorer and the same error -__-

suggestions guys please? thanks! I would rather not do ADB.

Same here. I then reboot into recovery and run fix permissions.

I also noticed BIG battery drain, even though I am only using the lockscreen one which shouldn't affect battery life that much ...

No ideas how to fix the battery drain issue?
It's severe ... (30% drop sometimes within 1 hour)

NfcMod for CM 10.2 Nightly

I just added the apk for CM 10.2 from the sources of Nightly 20131018.

The thread is also imported into DevDB and you have the new apk in the Downloads section above and you can use the Bugtracker for problems or the Feature Request section for requests of new apk.
