[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] sloheim:
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?
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] sloheim:
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 :(
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] sloheim:
No, but I may get it for this. What a bummer.
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] sloheim:
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!
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] sloheim:
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.
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] chrismurphy:
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.
[Sprint Galaxy S 5 Q&A, Help & Troubleshooting] chrismurphy:
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

and also

Wake lock 1027 NfcService:mRoutingWakeLock: 1h 6m 26s 537ms (0 times) realtime

Wake lock NfcService:mRoutingWakeLock: 1h 6m 26s 537ms partial (0 times) realtime

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.

[T-Mobile Samsung Galaxy Note 3] Mortifix:
Hello all, I am a fairly new T-Mobile user and I had a few questions about the service. I am a little confused about the service that is being reported on my phone and I don't know if this is something with T-Mobile or android. When I have service I will have the traditional bars and the 4G indicator. Well I was in the store today and I never get service in here while I'm in the back of the store but up front I get 2 - 3 bars. While I was in the back of the store my phone was reporting 5 bars but no data and I am unable to text or call. When I move to the front, the bars will drop to 2 bars and I get 4G. My question is why is my phone showing 5 bars when I have no service? Also, if I did in fact have 5 bars.. shouldn't I be able to text without data? I did have Network Signal Info installed that I was using to monitor my connect but I didn't have it installed at the time because I just installed Darthstalker ROM (not the issue because it was like this on all the other roms). Anyone have any experience with this? Thanks!
[T-Mobile Samsung Galaxy Note 3] speedy1979:
The next time you want to check signal strength don't rely on the bars. Instead go to settings>general>about device>status your signal strength is indicated in dbm and asu. No service if I remember correctly is -115dbm.
[T-Mobile Samsung Galaxy Note 3] Mortifix:
I have attached a few screen shots of when I disabled data and tried to send a text. It looks like its getting a pretty strong signal to the celltower. I am using 8sms app.. would that have something to do with it? Thanks.
[T-Mobile Samsung Galaxy Note 3] Mortifix:
Ok just a little update. It looks like my phone is picking up a Cingular tower as shown under net operator: 310410 which is giving me such high service when I don't have any. When I connect to the T-mobile network, it shows net operator: T-mobile and the service drops to the usual level. So I am able to send txt's and make calls without data and it is a case of no service.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
Hello,

I have problems with my samsung galaxy s3 I747M running 4.1.2 rooted battery. It's the original battery that came with the phone. I broke the original cord that came with the cellphone but still have the wall adapter so i was using a micro usb cable that was laying around in my house for about 3-4 days. I had no problems. Yesterday i went to sleep with the battery still at 40% and i shut the phone down. In the morning, when i tried turning it on it wasn't, so i plugged the charger and turned it on to see the battery was empty. I then went back to bed and two hours later it only charged to 31% and the phone was VERY VERY VERY HOT, the battery was not as hot as the phone was and there is no bulge on it. Ever since while tyring to charge my phone, it gets extremly hot and it charges slowly. When i turn it off and remove the battery then let it cool down and put the battery back it the % changes. For instance, 21% becomes 10%, 41% becomes 34% etc.

I tried using a different cable and a different wall adapter, i used my dad's samsung cellphone (flip phone) charger cable and outlet (which is a 5V 0.7A output).

Is the battery dead or is my cellphone dead? Problems started happening right after I updated xposed framework to the latest beta and updated keepchat and installed xprivacy. I uninstalled xposed framework and the problem is still there. I charged the phone to 34% just now and it lost 5% in about 5 minutes while being idle.

Charging via USB instead of a power outlet leads to slow charging and very hot cellphone too.

The phone is also a little bit hot when i put it against my cheeks when it is turned off.

Here is a screenshot of the very odd battery graph i have...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] crazymonkey05:
Looks like your battery is probably dead....but just to be sure why don't you flash back to stock firmware and see if that helps
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
I think I will avoid flashing stock firmware since the battery acts very oddly and I don't want to take the chance of it dying in the middle of a flash. I will go buy a new one tomorrow and check if it was the problem. What else could cause this problem if the battery turns out to be good?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] crazymonkey05:
Bad connection maybe
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
Just bought a new battery, cellphone still hot as balls when charging... Gonna try to reflash an old backup since the new battery is 52% charged...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
Just restored, looks like the problem persists... Any other solutions?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] BWolf56:
Did you factory reset?

Flashing stock might actually be your best bet atm. While it can be scary to flash with a *maybe* faulty battery, if it's plugged, it should be fine.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
How can i flash back to stock without using ODIN on computer? The only cable I have for my phone does not transfer files.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
You can use mobile odin. But only use that to flash the same firmware build as you have now, just to be safe.

If that doesnt help, getting a samsung S3 cable is the next logical step. They're pretty cheap online these days.

Id probably get the cable anyway if you can. This way you can fladh using Odin. Mobile Odin will flash the firmware, but only parts of it. So by getting the cable and using Pc odin you can flash the full firmware. Up to you how you want to proceed there, but if mobile odin doesnt solve the problem, you'll still have to question if a full firmware flash might help.

Hope that made sense!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
I am going to purchase a cable tomorrow and flash stock using Odin and see if it fixed the problem. If it didn't i'll root, reset my recovery to stock, reset flash counter and reflash stock. If I go see my carrier (Koodo) and ask them to send it to samsung, do I have good chances of getting it fixed/getting a replacement?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Kansas_32:
It should be fine. I sent my S3 a month ago and they fixed it, they only briefly check if you have rooted or not, they don't check for flash counter or something like that. As long as you are in warranty, they should fix it for free.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
I just ran triangle away and then used odin to flash stock and when I open my phone in download mode it shows CUSTOM BINARY DOWNLOAD : YES (1 counts). Do I have to re-root and re-run triangle away then re-flash stock?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
Maybe. Try rooting using Towelroot. Not sure if it'll work on older firmware though. If it does, install SuperSU from the play store, open it and update the binary. Now triangle away. Next choose full unroot from the SuperSU. Done.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
I flashed a stock root injected 4.1.2 rom on my cellphone, ran triangle away and it worked, my phone now shows official on the download mode screen ans no custom binary download. Can I safely send it to samsung now? I just reflashed the stock rom to remove root.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
Should be fine.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SterneSchreien:
Just got my phone back from samsung, they changed the faulty motherboard and my phone now works fine. The battery is not in good shape tho, the 0-1% charges while the phone was broken must've killed it. I'm going to buy a new one.

On a side note, is there any root methods that don't trip flash/KNOX counter for android 4.4.2? They updated me.

Are there any flashable boot animations for a rooted galaxy s5 with safestrap?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] b..c:
HI Everybody,

Ok so my problem is that I can't access my custom recovery on my s4 SGH-I337.

My s4 is running android 4.2.2. It has root access and the bootloader is unlocked. I installed clockwork mod recovery touch 6.0.4.7 jflteatt using the app Rashr. When I try booting into clockwork I get blocked. It says "system software not authorized by at&t has been found on your phone." And then tells me to turn off my phone and go to the nearest at&t store. Also at the top left corner it has : ( Secure Failed:Kernel ) in red.

Sorry if there's a thread already about this but I couldn't find anything using the search engine. Thanks
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] jmjoyas:
There has never been a boot loader unlock for the sgh-i337. There was only a workaround - Loki. That too worked only for the MDB/MDL firmware. If you have MF3 or newer, boot loader is locked. So, no custom recovery and kernel. The only working recovery is safestrap.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] b..c:
Hi jmjoyas,

Thanks for replying! After reading your reply I finally understand what's up with at&t's s4. (I official dislike at&t even though their service is dependable) I was really looking forward towards cyanogenmod :(:(:crying:! But I still have some hope that my bootloader is unlock. This get's really complicated but when I first got my s4 it was came pre rooted and I believe it was refurbished in Asia. Weird right, but my phone dealer was chinese so who knows. Anyway so when I had Rashr boot into recovery I came across a loading screen with a samsung in print and under it was the word custom and under that work was a picture of a lock unlock! I believe that lock sign is the bootloader based on my rooting experience on my mom's galaxy nexus. I have a picture of that loading screen, but I can't upload it! Is there another way to show it?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] sway8966:
As far as I know bootloader is locked for all AT&T S4 firmwares. So far we have a bootloader exploit call "Loki" only for the MDB/MDL firmware. There is no bootloader exploit for MF3, MK2, NB1, NC1 firmwares out yet.

You would see the "custom" word and unlock lock in every rooted AT&T S4. It has nothing to do with bootloader lock or unlock. If you unrooted (uninstall the superuser) your phone that symbol would go away.

Could you please tell us your phone firmware (baseband, build number, etc.) so that we can help you more.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] :
Study up by reading thru General threads. Several to get you up to speed on upgrading and SafeStrap. There is one GPE rom that will run on your phone. AOSP based. It is General alos. But, read that thread carefully. There are very specific flashing/upgrading instructions and some bugs. I would probably get familiar with TW roms on SafeStrap first--:good:
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] b..c:
Hi sway and rugmankc,

Thanks for giving me a better insight on my situation. Sway you're correct. When I boot into recovery after I un installed super su that loading screen was gone. Case solved! And rugmankc I'll look into general alos. Thanks guys for all your help including jmjoyas!:fingers-crossed::) Thanks again!
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] b..c:
And I forgot to answer your question sway. I have MF3 :( . Hopefully there's will be a bootloader exploit but until then I'll keep my fingers crossed:fingers-crossed:!
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] :
I don't need SafeStrap, so not up on it. I believe process would be upgrade to NC1, root with Towelroot, and use SafeStrap. But, check all that out before doing. May be steps in between. Make backups before and after as best you can. :)

Hi, I have an S4 that I got from rogers (i337m). When I initially rooted it I was running cyanogen mod ROM but I had around 5 GB of storage missing. I read from somewhere that going back to stock would fix this problem. I used Odin and followed a guide and went to stock 4.2.2.

Figured it out

From 2:45 it had 69%

to 7:19 it had 64%

so around 1% PER MINUTE when it use!!!!
[Moto 360] ern88:
Well, I hope the battery is 500-600 mHa. That would give the 360 about a 2 day and a bit life between charging. I just wish Motorola would release the specs!!!!
[Moto 360] Note10.1Dude:
Smartwatches are going to seriously need the ability to generate power from the motion of wearing them. Or an internal nuclear-decay power source. I really like the 360, but think we may still be a generation early on low-power screens and chips to be able to make a thin watch that will last for 3 to 5 days, which would be ideal.
[Moto 360] brizey:
I would rather have quick and easy charging than 2 day life. I would much rather have a smaller/thinner watch than one that can go for three days for no reason (we have electricity in our house!). Why would you not charge it at night? The only scenario I can think of is if you forget by accident or don't seat it in a charger properly. A day charge while you **** shower and shave fixes that better than a bigger battery you have to lug around the other 364 days a year.
[Moto 360] bbish937:
Smartwatches are tough with screens on such a small device its hard to get enough battery to power it for long. This kinetic energy idea would really be brilliant I don't know what the conversions would be but I mean my watch that I have now runs only on kinetic energy, granted theres no display but it has to provide some energy no? Maybe a combo of a battery, kinetic, and solar power could give smartwatches the extra juice they need?
[Moto 360] Gadgety:
Forget kinetic, if by kinetic you mean the wrist movements. It's not even remotely possible to use. There are some variations that could work:

It's going to take a while. A really long while. Very, very long. Have a look at regular watches, not mechanical, but kinetically charged quartz. How long did that take to develop? 18 years, at Seiko, and not long after, Citizen just overtook the tech with solar charging. Quartz watches are incredibly frugal. Quartz, an amazing achievement that took at least 30 years to develop for the wrist, and to industrialize. Trivialized today, but when it happened it was amazing. For a while there was also tech that used the body's chemistry to charge the batteries, but it wasn't really competitive, not even for frugal quartz watches. What we call smartwatches are in a different league though, microcomputers, with processors, radios, colorscreens... which are just beginning to be able to last a couple of days of battery power. Being small enough to fit on a wrist is an incredible development in and of itself. Kinetic charging from the wrist - run a marathon and your smartwatch, through a kinetic charger, would last perhaps a few seconds, not enough to even boot up. So kinetic, good luck.
[Moto 360] anisjolly:
The following article states that the moto 360 will have a battery life of around a week - with wireless charging.

http://www.theverge.com/2014/7/15/5903241/i-saw-a-moto-360-this-morning

If this is the case, and as per the article - it states that the moto 360 will have more improvements before release - I'd be happy with the 1 week battery life!
[Moto 360] Hardcore73:
I think the week without charging is if you keep screen off. Every demo I have seen the screen is automatically off and when they wake it the screen turns on.
[Moto 360] vdefender:
I doubt I will have any issues with battery life with the 360. The way that this is meant to be used is mainly as a watch. Lift your arm, check the time and you're done. You can also check the weather, but how often do you really do that? The other thing that having this on your wrist will do is provide very quick access to notifications. When I'm in a meeting at work, and my phone vibrates in my pocket. Now I wonder if it's worth it to pull my phone out in front of everyone, unlock the screen, pull down my notification and read it. that's a lot of steps just to see if it's important and potentially distracting to the meeting. With the 360, I get a vibrate, and smoothly lift my wrist as if to check to the time, and the notification will be right there and i'm done.

People shouldn't be using their smartwatch to brows the internet, type, or do anything other than a quick glance, in my opinion. In most cases, you will want to just pull your phone out for productivity purposes.

Anyways, I'm not even the least bit worried about battery life. I just want it now!! :D
