Default [MOD] NFC With the Screen Locked/Off - UPDATE for BLG8/BLH1.

Update (30.08.2012): Added Packages for LFB. And a beta package for LH7: http://forum.xda-developers.com/show...&postcount=180

Update (24.08.2012): Added Packages for BLG8, BLG9 and BLH1 (nfcmodSGS3_lockscreenBLG8_BLH1.zip, nfcmodSGS3_screenoffBLG8_BLH1.zip and nfcmodSGS3_stock_deodexed_BLG8_BLH1.zip). Update for LFB will follow soon.

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.
I also created a ZIP to go back to stock NFC. CAUTION: Use the stock zips only with the right firmware. The deodexed stock should work for all stock firmwares released yet.

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

This mod works for at least for ALE8, ALF1, ALF2, ALF5, ALF6, BLG8, BLG9, LFB and BLH1.
For users of the AT&T S3 (SGS-I747), I created a version for this device too: http://forum.xda-developers.com/show....php?t=1740614. Please give me feedback, because I do not own this device and I cannot test the Mod on it!
For users of the Sprint S3 (SPH-L710), I created a version for this device too: http://forum.xda-developers.com/show...php?p=28046812. Please give me feedback, because I do not own this device and I cannot test the Mod on it!
For users of the T-Mobile S3 (SPH-T999), I created a version for this device too: http://forum.xda-developers.com/show...php?p=30920478. Please give me feedback, because I do not own this device and I cannot test the Mod on it!

Incompatibilities: This Mod seems not to work with CM9. This mod does not work with LFB now. Maybe the BLG8 version works for LFB8 but I have to validate this or someone has to test it. I will provide an update for LFB the next days.

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.

Are there any implications for battery life of NFC being enabled when the screen is off?

I've not yet tested it but I think so. But I think the effect on battery life shall be less then for example bluetooth activated all the time, because NFC uses less power. But it can happen your SGS3 comes near a NFC-Tag and an communication starts without your knowledge. But this NFC-tag have to be very near to your S3 and normaly it cannot do anything on your phone if you haven't configured it so... But is's up to you. I prefer the lockscreen variant yet.

Thanks. I was thinking more of the impact of it always searching rather than an unintended connection. Will be interested to hear people's feedback though.
