Hi everyone...
I was at the gas station last night, and thought I'd try using NFC/Google Wallet to try paying for something for the first time.
I went in to turn on NFC, and found that the option is completely grayed out. (The button is set to "on", but its grayed out, and cannot be turned off)
Android Beam is disabled/grayed out.
S Beam is enabled, but I can't seem to change it.
Tap and Pay is disabled, and says, "NFC is turned off".
Something is clearly FUBAR'd here.
I've tried rebooting a couple times.
I've tried pulling the battery (yes, its the original OEM battery).
I've tried wiping data for NFC.
I tried re-installing the stock ROM, and it didn't fix anything.
Any other suggestions?
Thanks..
Just a follow up here... I've also tried a complete wipe of the device... still no go.

Still running ktoonsez kernel ?

Yes.
And when I did a complete wipe and re-install, I was able to verify that its happening with the stock kernel also, so I don't believe it to be a kernel issue.
I was able to try a different battery today... from someone else with an S5, and the same problem exists.
My next step is to try unrooting and going back to complete stock... obviously I'd like to avoid this if at all possible.
Any other suggestions? Anyone?
Well, I did it today.. unrooted, went back to full stock everything... and I still cant change the NFC setting on my S5.
If anyone has any other suggestions, I'm more than open to anything at this point...

Do you have insurance ? I would think about taking it to a Sprint store and see what they say. You might have a hardware problem

No, but I may get it for this. What a bummer.
Could someone be so kind as to post a copy of their /data/data/com.android.nfc/shared_prefs/SamsungNfcPrefs.xml file for me?
Also, can you tell me if you have an nxpdevicehost.xml file in that same directory?
Thanks!
Here are the latest details. I feel like I'm so close, yet so far.
Background:
When I would reboot my S5, the NFC setting would be set to "On", but disabled and wouldn't let me change it. On top of that, my phone would never go into Deep Sleep. After exhaustive research, it appears that the phone was constantly trying to enable NFC, which prevented it from hitting Deep Sleep.
I've dug thru a lot of the AOSP code, and discovered the following.
- If I change the nfc_on tag from true to false in my NfcServicePrefs.xml, and add a line setting first_boot = false, NFC does not try to turn on when I reboot the next time (This solves my deep sleep problem).
- If I try to manually turn NFC on after that, it gets stuck the same as before I made any changes to the XML file.
- Based on this code, it looks like there is a java call to "mDeviceHost.initialize()". I'm guessing this is where I'm getting borked.
- The initalize function, found here, seems to want a file called NxpDeviceHost.XML. I cannot find this file anyplace on my S5.
My assumption here is that Samsung forked this process and made their own internal changes. I'm looking at AOSP code, but that doesn't help if Samsung changed things on their end.
Can ANYONE help me debug things from here? I'm a developer by trade, but have never worked in JAVA (although I've figured out how to read enough of it to become dangerous). I dont need a lot of hand-holding... just a push in the right direction here.
Thanks!

I have the same issue on an LG-e970. The NFC option is checked and grayed out, I can't change it. It's always been this way since I got the phone. The new problem in the past 48 hours is some OTA update is causing Nfc Service to prevent the phone from sleeping, but I have no idea what it is. I thought maybe Google Wallet so I uninstalled it, but the problem remains. It happened well after the Android 4.4.4 Cm11-M8 update for this phone. I filed a bug at code google dot com bug ID 74037, which this silly forum won't let me post because I'm too new and it doesn't understand the difference between a google code URL and spam.
Weird. So I powered off the phone, let it charge to 100%, booted in safe mode, Settings > Storage > Cache and reset it, rebooted in normal mode, and let the phone sit unused for 1 hour. The problem with Nfc Service is not occurring, the phone is sleeping most of the time now. When I go to Settings > More > NFC is unchecked, not grayed out. Inexplicable, because I've had no way to uncheck it.
So I just checked it, and it immediately grays out so I can't uncheck it again. I'm leaving the phone unused for another hour and see where things are at.

Nfc Service is once again the top battery consumer and won't let the system sleep. The bugreport for the state with the problem (in contrast to the report for the state without the problem):
many instances of:
07-24 11:23:16.870 1064 8319 E NFCJNI : emergency_recovery: NFC stack dead-locked

Wake Locks: size=1
PARTIAL_WAKE_LOCK 'NfcService:mRoutingWakeLock' (uid=1027, pid=1064, ws=null)
I've booted recovery, formatted /cache and erased Dalvik cache, see where that goes... obviously if I can figure out how to disable the NFC option again, that solves the no sleep problem.

Sorry to bring this thread back to life, but I'm having the same issue and would like to know which solution worked out for you. Thanks.

***UPDATE***
I upgraded to ParanoidAndroid and had to use a different apk. I don't know who made this one (i downloaded like 10 from xda and tried about 4 before it started working), but here's the winner:
techneesh.com/paranoidandroidnfcscreenoff.apk
*****************
Hey guys,
I searched for hours but could only find reports of people *NOT* getting this to work on the Verizon GS3 (hence the name of the thread).
I tried hacking my stock Nfc.apk using dex2jar & modding the smali files (after looking up the appropriate values to change using decompiled dex2jar classes.dex's nfcservice.java), but after much frustration decided to just go ahead and try the existing versions out there.
By the way, if anyone is looking for how to do this (decompiling/modding/recompiling an apk) with 4.0.4 (and getting the 'bad magic number with smali/baksmali), refer to the comment on May 8th in this thread.
I'm pleased to report that mayhemer's AT&T version (for the SGS-I747) works for us Verizon folks!
You can grab it on his thread here.
I've also uploaded it to my server. Here's a direct link:
techneesh.com/Nfc.apk
I posted this in the Development section because I would really like to encourage devs to work on modding Nfc functionality further. Also, this is a more advanced mod for a system app.
Google Wallet did not throw errors with this .apk (as it did with others), although I have not tested it yet.
NFC reads trigger the nfc tag's function and the alarm/beep, but do not turn on or unlock the screen (while it is off).
Also, I just got a whole bunch of NFC tags in and plan to make some cool products for them... if you have any ideas let me know on my 3D-printing-on-demand-for-xda-samsung-gs3-folks thread.
Note- I am on Bean's Custom Stock R3.1 07/28 (I know, I need to upgrade)
4.0.4, SCH-I535, Baseband I535VRLF2, Kernel 3.0.38imoseyon+, Hardware I535.10
Instructions for apk:
1. Get apk onto your phone
2. Stop NFC (or else your phone will start lagging // freezing after the next step)
3. Copy the apk to /system/app/ with a root explorer and overwrite the existing Nfc.apk (you should make a backup first)
4. Change permissions to match other system apks (rw-r--r--)
5. Reboot & re-enable nfc. Profit. Share your uses.
For zip you should be able to just flash in cwm.

oh man, don't get me started!
think about it - you get to your desk and want to tether / turn on music / silence phone. just tap it on the nfc sticker on your desk. done.
you get into your car and want to enable gps / turn on music / navigate somewhere. tap your phone to the nfc sticker. done.
i have a lockscreen for security and even though it only takes a second to open it still adds up over the course of the day. the ability to quickly do (any) task on your phone without unlocking it or even pressing a button is huge.
for example, I canceled home internet last year when I got LTE but this means I have to turn on tethering every time i sit down at my PC. using a tasker nfc-activated command I can just touch my phone to my desk and it's on. time saving and just fun.
or maybe you are in a meeting and miss a call and want to call them back - have a pre-programmed nfc sticker that will command your phone to set an alarm for (e.g.) 1 hour. tap your phone to it without fiddling /unlocking/interrupting your meeting further.
what really made me think of this is while I was looking for something behind a wardrobe and wanted to turn on my LED flashlight on my phone. how cool would it be to have an nfc sticker (on your keychain? on a sliding mechanism on a custom techneesh.com case on your phone?) that could basically act as a 4th hard button to do a custom function (in this case, turn on the LED flashlight without 1. turning on screen 2. unlocking 3. going to home screen 4. finding LED flashlight app and opening)
and yes, this is for real
I'm trying to get this to work on CleanROM 2.5, with the G7 baseband. I followed the steps correctly, but it doesn't to anything different than the stock NFC
I can still read my tags when screen on and unlocked, but i get no response with the screen off or on and locked.
Triskite, did you modify the .apk from the linked At&t SGSIII thread at all? If not, would it be safe to try the other apk's listed there?
Thanks!

the apk worked as-is for me - only thing i can think of to try is to turn ON a lockscreen? (I use the pattern security one)
safe? I certainly can't assure that... but would I try them? yes.

I flashed the nfcmodI747_lockscreen.zip flashable from CWM and it works like a charm!
Once i did this, i wanted to see if the screen off nfcmodI747_screenoff.zip works, and it sure does (again, flashed via CWM)!
Don't know if it matters, but i did not disable NFC from settings before i flashed them via CWM.
Thanks again!
Just saying this is as of the moment the most unsafe mod someone can implant or put a nfc tag somewhere to run malicious code on your device. While I do not condone hacking of any sort, I know the possibilties of what these hacks can do from different forums (not naming any).
TLR, caution with this one guys. Especially if you're using wallet using my guide......
Ok...what are these tags you're talking about? I've never ran across NFC tags in "the wild"...do you buy them and then tell your phone what to do when it reads a certain tag?

Yea, I understand the risks and all.
I agree that it is a major security vulnerability for someone that wishes to highly protect their information.
I just wanted to try it for a proof-of-concept kind of thing.
Honestly its pretty quick to flash these via Cwm. I went back to stock Nfc.apk for parties/bars this weekend (Too many people close to me for security comfort), then today I flashed the lock screen version for my school week.
It would be really cool if it were possible to toggle this.

Can somebody post the stock nfc apk file(s)? I guess they are needed to take the OTA update after mucking with Wallet, and i didn't save them.
I just tried the nfcmodI747_screenoff.zip with the latest paranoid android (2.16) and it does not work. The NFC settings disappear entirely.

I have flashed synergy (ICS), jellywiz and now cleanrom 2.5. I don't know if they've modified anything in the NFC.apk, but this is what I have.
If you wanna guarantee its ok, you can pull it from the stock ROM.

True, but this involves active running processes like GPS which can drain your battery. From my experience, NFC has no noticeable extra drain, not even the screen off modified version. Not to mention how easy it is to use the NFC programming apps versus Tasker, IMO.
What worked for me after trying and trying to find a way around ACCESSIBILITY SETTINGS for hours...was just:
1: Clicking the green setup arrow.
2: Turning off Wi-Fi.
3: Clicking NEXT.
4: Choose KEEP YOUR APPS & DATA.
It then gave me an option to SIGN IN....and immediately ACCEPTED my most recent password!
SIMPLE, I KNOW...BUT hell, it worked for me. Sometimes, the most obvious things get overlooked. Was this just a fluke or is it really that easy to bypass?
I may have missed a step, as I'm no longer in the setup situation...but let me know if this helped you! :good:

On Friday I updated my rog pgone 5 to the latest version. yesterday suddenly the fingerprint sensor stopped working, restart the factory mobile and solve it, but at 24 hours the same thing happened again.
does anyone know what happens?
Seems to be a common issue. A log when it happens may help to find a fix.
There is a lot of log spam to dig through, so I wasn't able to pull one on-the-fly

I have been able to solve it, I did a system erase + deactivate facial recognition + fingerprint. turn off the device, turn it on again, turn everything on again and restart. for now it works. When I charge the phone, I hope it won't happen again. (After charging the phone, it gets quite hot and the sensor stops working.)
Alright, well good luck with that.

My phone is randomly logging battery status. Sometimes every few seconds.
The log is always the same. Battery level greater than zero, with date and time stamp.
Sometimes it's a few seconds apart, sometimes it's a minute or two. Overnight it was exactly every 30 minutes. It's writing the log to a text file. It appears to have been doing this ever since I got the phone. Only yesterday, it just decided to start notifying me of this. An Office notificaation pops up with "Batterylog.txt is ready to download"
Every.
Freakin'.
Time.
Haven't figured out why or how to stop the logging, but turning off notifications for office at least stopped the annoying notifications.
I have an S22 Ultra, all stock and up to date. Any way to stop it?

Yeah. There just isn't a lot of info there. I was mostly curious as to why whatever it is feels the need to log the battery status every 30 minutes, and why the only info given is "battery level greater than zero". That's pretty obvious by the fact that the phone is on. I'm even more curious as to why, all of a sudden, it started sending me notifications for it. I haven't changed any settings in forever.
I'd like to know what app it is, but there is absolutely nothing to go on. The file size is up to 1.4 kb since 11/03 04:37. I wonder how long it will take to get to 1 GB.
I'm sure there has to be an explanation. One of your apps is doing it, just not sure how to figure out which one it is.
I agree. I'm sure you've thought of this but it might be time to uninstall your apps one at a time until you figure out which one is responsible for it.

That thought occurred to me, but I opted for planB instead. I ordered a Pixel 7 Pro last nigjt.
Not purely for this reason tho. Phone tookansty fall a couple months ago. Nickel size chunk of screen gone, and it hasn't been fully right since screen replacement. Something loose inside, among other things.
So I turned off Miui Optimization because I wanted the always on display to always been on (apparently if you disabled Miui Optimization, it wouldn't turn off after 10 seconds). It worked, but I lost some things like the haptic vibration or the Gaussian blur of the interface. I need help, I enabled Miui Optimization again but it didn't fix it (I restarted my cellphone more than 5 times). I don't know what to do and I'm not able to find a solution.

Yeah, I was able to find a solution for it. I suffered the same thing you have, phone was back to normal when I plugged the cable to charge it. I installed an app called "Hidden Settings (if you search it on the play store as "Hidden Settings Miui" it'll appear on there). Open the app and go to "hidden" at the bottom of the interface, then search for the battery options and its gonna be one of those 4 options.
In my case, the problem was with the second battery option. It was enabled and I had to disable it, then it started working like nothing happened.
I hope you can fix it, if you need help just answer this saying it.
