Default [MOD] NFC With the Screen Locked/Off for SGS-I747

In the Samsung Galaxy S3 Stock ROM NFC does not work when screen is off or locked. With this mod NFC also works when screen is locked or off.

There are two versions. The first just enables NFC, when screen is on, but it also worked when it is locked. Also with a PIN or Password-Lock everything is fine. But it disables NFC when the SGS3 is in standby and the screen is off.
The second version let NFC active all the time, even when the SGS3 is in standby and the screen is off.
Nothing else is changed in the behaviour of the NFC.
There are also two zips to go back to stock Nfc, one is odexed and one deodexed.

All ZIPs have to be flashed with CWM. You should wipe Dalvik cache after flashing.

This mod works for at least for I747UCALEM. This mod does not work with LFB now. It also doesn't work for CM9 or CM10. I will provide an updated Mod in the middle of August because I am at vacation now.

Please give me feedback, because I do not own this device and I cannot test the Mod on it! I just ported my MOD for the international S3 to the I747.



Disclaimer: As always, I hereby absolve myself of responsibility for any damage you cause to your phone by flashing this. There is inherent risk in modding your device, and by flashing anything in this thread you are taking that risk into your own hands. If something goes wrong, I will try and help. You should always make a Nandroid Backup before flashing.

To ROM Devs: You are more than welcome to use this in your ROMs! Just shoot me a little bit of credit in your release post!

Thank you: Geniusdog254 for the idea and the infos in your thread.

I can confirm that the Lockscreen one is working!! Thanks a bunch.

Do you know how this affects battery life? What about for the "off" one?

I used the Screenoff version for about a week and I didn't recognise battery drain. There should be an impact on battery but it is less than for example always active bluetooth.

Just ordered my set of 15 NFC tags, should be here this week, looking forward to trying this out

Any update on the battery use with the screen off version? It'd be great to have the screen off version, but if it costs battery then it's almost as good just using lockscreen. Thanks to the dev for creating this, great hack

How do I determine if I need the odex or deodexed stock ROM?
