I modified the NfcNci.apk of different bases and ROMs to offer you the ability to use the NFC chip of your T-Mobile Samsung Galaxy S 5 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:
  • lockscreen and screen off
  • lockscreen
  • unlocked


USAGE
  1. Rename the attachment to NfcNci.apk
  2. Backup your /system/app/NfcNci.apk and NfcNci.dex (if existing)
  3. Delete /system/app/NfcNci.dex (if existing)
  4. Replace the original in /system/app - to keep permission use adb:
    • adb remount
    • adb push NfcNci.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


Changelog

19.05.2014 - thread opened with Stock 4.4.2/Project Infinity

Please don't forget to thank if it works, if not we will make it work.

2 questions.

1) does it effect battery life if you have it so you can use nfc with screen off
2) can this not be done with Wanam? I see the option, just not sure if it actually works thru Wanam.

Hi. Excuse the delay, I forgot to set the notification for this thread.

Did you try the version from op? I don't think t-mobile is using much different framework, so it could work.

1) For sure but I haven't read of anybody that it is noticeable.

2) I don't know Wanam. If you prefer it use it. There are also other Xposed mods for some time. I don't know how these mods implement the functionality but I know that the S5 has a much different NFC implementation than other devices i.e. because they handle the usage with the S View Cover.

Stephen, can you describe what you changed in the nfcnci.apk for this modification? I do not think your modification would work with my ROM and would like to make the modification on my own. Thanks!
