[Q] NFC not working - Sprint Samsung Galaxy Note II

A few months back, NFC stopped working on my Note II. I have programmed a number of NFC tags in the past and used them on a daily basis. There's an NFC tag on my car phone mount that automatically starts up Car Home Ultra, turns on Bluetooth, turns off WiFi, etc. Just suddenly stopped working. NFC is, of course, enabled in the settings.
At the time, I was running a stock 4.3 MK4 ROM, rooted. I've since used CM11 and just a few days ago installed Community ROM 3.2+ (4.4.2, NE2 modem). Neither of them worked, which leads me to believe it's a hardware, not software, problem. It's my understanding that the NFC chip on this device is embedded in the battery cover, and is connected via the two round copper conductors. I've ensured that they are clean, etc., still no joy.
Can anyone offer any words of wisdom?

Well if it is not working on any rom then it is most likely a hardware issue. The chip is in the back cover. If you know anyone who has a N2 maybe they will let you try using their back to test. If it turns out to be the nfc chip then it is not very expensive to replace.

Thanks for the reply.
Yes, I DO know someone that's near the Jersey Village area of Houston, and I owe that gentleman a few beers (hint, hint).
I found this on eBay. Judging from the 3M logo I see in the second photo, I would assume that the NFC antenna is simply held onto the back cover with adhesive. So replacing it is simply heat, pry, peel, and stick? I'd pay $4.29 to try it out. I'm nearly certain that's my problem.

I will be back Tuesday and available Wednesday.

Galaxy Nexus GPS not working after dropped into water.

Hi,
So, I slipped into a waterfall together with my GN, for 20 seconds perhaps?
I took apart the the battery and let it dry.
Back home I used hair dryer in hope to dry the internals with heat.
I tried to turn it on but failed, then I proceed to put it into rice.
This morning, the phone was working nice, although haven't tested all the functionality, the basic ones are working fine now.
Except for GPS, I tried turning on Waze, Google Map, GPS Test. Usually there's an icon of GPS in the notification panel.
And it's not there anymore, I'm able to turn on the GPS from UI, but I'm guessing the GPS module has been fried.
How can I make sure it's not software problem? I'm using stock Jelly Bean.
How much does it cost to repair the GPS module if I sent it back to Samsung?
I am relunctant to send it to Samsung for repair because it'll be months without my GN just for a GPS module, sigh.
Thanks.

Curious if you ever figured this out
I have a gnex that I repaired after it had gotten dunked, and I'm also having GPS trouble...

NFC problems

I have a 3500mAh extended battery that I bought off Amazon. I forgot the brand name lol but I don't think it matters. Problem is that my NFC chip has stopped working with this battery. I tried using Google wallet at a vending machine that it always used to work, and now it just sits there and shows the wave graphic as it's loading, and never competes the connection.
I'm not sure if I damaged the antenna somehow or if it's possible that the antenna is now dead, because it used to work a couple of days ago and now, nothing. I haven't tried using android beam with another phone yet, or testing it with the stock battery as I'm not home (I'll try those later) but any thoughts are welcome.

does the battery say it has NFC? if not, it will never work
the antenna is in the batteries and without that, NFC will never work.

Funny, mine started doing that after the latest update. It took the .53 left on my google card ok, but I can't get it to charge any of my cards. And I thought it was just me but maybe not.

I'm pretty sure the battery has NFC. The amazon listing said it did, and it was actually working until a couple days ago (probably the latest update)

Just tested it with my girlfriends GSII, and I can easily send links, youtube videos, maps etc through NFC/Android beam both from my phone and to my phone. So my guess is it's Google Wallet.

Bluetooth not turning on consistently

Like many of you, I've been having some trouble turning on bluetooth and it's been getting more difficult to get the bluetooth turned on. I don't have any other problems with other features, like GPS or wireless connections, but more often than not, I cannot get the bluetooth to turn on unless I reboot and toggle airplane mode a bunch of times.
As the first step in trouble shooting the problem, I decided to go back to a stock ROM since that has seemed to work for others. I deleted all of my user data and formatted system, cache, data and davlik cache before each ROM load. I first tried the stock Gingerbread ROM but the Bluetooth was still not working consistently. I then tried the ICS stock ROM but again the bluetooth did not work correctly. On each ROM, I tested the bluetooth thoroughly by power cycling the phone, using airplane mode, and trying to toggle bluetooth repeatedly. I was able to turn the bluetooth on in each ROM but it would only come on about 10% of the time and there did not appear to be a pattern of reboots or software manipulation that I could do which would cause it to turn on. Nothing seem to work so I suspected there must be a hardware problem.
I opened up the phone tonight and on a hunch, I reseated the antenna (the white antenna on the right side of the phone when it's laying on its face) by removing it and reattaching it to the board by the two ends of the antenna but did not remove it from the middle clip. I'm not sure what happened, but when I restarted, I had no wireless service which made me think I was buying a new phone tomorrow :crying: but the bluetooth was working every time! I opened the phone back up and totally removed the antenna and reseated it. This time when the phone started, I had great wireless signal and the bluetooth worked perfectly. Granted, it's only been a few hours but it's never worked so consistently since I reseated the antenna. No idea if this will last but it seems like in my case, there was an issue with the connection to the antenna. I'm not even sure if that antenna is used for the bluetooth or not.
If this works for the next couple of days, I might try buying a new antenna. If you decide to remove the antenna, make sure that you use a needle nose pliers to remove the two ends of the antenna. You do not want to pull the antenna off by the wire. Also, if you reseat it, make sure there is equal slack on each side from the middle clip because the antenna needs to fit between the two golden lines printed on the case. Otherwise, when you put the case together, it will pinch the antenna. As with all hardware changes, THERE IS A CHANCE THAT THIS WILL SERIOUSLY DAMAGE THE PHONE'S ABILITY TO RECEIVE WIRELESS SIGNAL. I thought for a few minutes I would be at T Mobile tomorrow buying a replacement.
I'll report back if this works long term. Sorry if someone already mentioned this as a solution. I did quite a bit of searching and had never heard of someone trying this.
The attachments show the location of the antenna in the case and the close up of the antenna. If you remove the back cover and unscrew the panel from the back, the antenna is right there.
Bluetooth seems to be a reoccurring issue in a lot of custom roms...for some people anyway.
If you want it to work flawlessly, as well as everything else, there's always stock 4.1.2.
Sent from my Moto X cell phone telephone.....
I tried going back to the stock gingerbread and ICS. I knew that bluetooth worked when I had the stock gingerbread ROM but now in the stock gingerbread ROM, bluetooth no longer turned on consistently. I wiped everything on the phone when I went back to the stock ROM and it just did not work. That's what made me think that there was a hardware problem and possibly a poor or loose connection.
I'm not 100% convinced that reseating the antenna worked because I don't know if bluetooth even uses that antenna but I wanted to post my experience with it. I would go back to a stock ROM first to make sure that it doesn't work there before messing around with the hardware.

WiFi is gone

I've had this tablet (SM-P600) for almost a year now & it has worked perfectly. Over the last week or so, the WiFi has been randomly turning on & off. Not just losing signal, but actually showing as off in the menus. As of this morning, wifi will not turn on at all. Just says "turning on" on the screen & sits. Never gets to the next screen showing all the open networks.
Everything is fully backed up so I went into recovery tonight. Did the full factory reset and wipe procedures. Tablet boots back like it is as supposed to, but wifi wont turn on when getting to that screen in the initial setup.
Tablet has been well cared in a case, not dropped, and not gotten wet. However I am still positive this is a hardware issue.
Any ideas for things I might try? Help!! Thx in advance
I've the same problem with my galaxy note 10.1 2014 edition SM-P605 :crying: Still haven't found solution
I am almost 100% certain this is some type of hardware problem. I tried flashing about 3 different ROM's and 3 different kernels, all of which successfully booted up. I finished by doing a 100% re-wipe (data & system included) & reinstalling a pure stock kernel and firmware. On every single revision, the words "turning on" would appear when clicking the WiFi option, but then it would get stuck. Message would eventually clear & I could continue using everything on the tablet . . . . . . . just no WiFi or Bluetooth functionality.
Final attempt was to gently remove the back cover. When lightly tapping around different points on the MoBo, the names of my local wireless networks would OCCASIONALLY appear. At one point they locked in & I really thought I had it. However, the whole thing disconnected again after a few minutes & I was back to square 1. :crying:
I never could figure out the perfect sweet spot to pinpoint the problem. My guess now is either a chip or ribbon cable that isn't seated properly, but I poked and pushed (gently!) on everything that was visible without removing any hardware other than just the back cover. Does anyone have a link to the layout of the motherboard that shows EXACTLY which piece is the WiFi/BT module? I did find an online disassembly tutorial with a random Google search, but for some reason they failed to identify this particular module.
Sorry for the long post, but I feel I am SO CLOSE to figuring this out once and for all. Just need a little more tech help to push across the goal line. Thanks!!

Sorry about that. It's just the initial release plain jane WiFi model. SM-P600
Update:
After a little more poking and prodding on the MoBo, I'm starting to see activity. Tablet will finally connect again, but will only hold the connection for 10-15 seconds and then drop back out. A few seconds later the cycle repeats.
I really wish I could find a good hi-res photo of the motherboard to help. HAS to be a simple loose connection, or maybe a not-so-good solder point somewhere???

never heard of 'em, is it a cheapo tablet? In my country there's a store of them (Allwinner 6.6" tablet with microSD slot, 2gb internal w/o bluetooth WIFI ONLY INTENDED FOR CASUAL GAMING, or should I call it kids only tablet, RM130 ($35))
That thing has a cheap plasticy housing, unneat design but has a pretty good performance (it plays dead trigger pretty well)

SM-P600 is Samsung's actual model number for the WiFi only version of the 2014 Galaxy Note 10.1. Most definitely NOT a cheapo tablet!! Although this wifi issue makes me wonder. I had the functionality back for about a day or so, and then it disappeared again. This has to be a simple case of a loose connector, but I sure can't find it. Ugh. Utterly frustrating.
oo...my bad
maybe software issue
This was sent from my Lenovo A850 via XDA mobile app.
What firmware version are you using because I am having the same issue. I manually updated to the september update (P600UEUCNI1) for the wifi version and started experiencing the same issue.
Same here. I think it's an issue with NII firmware.
*****PARTIAL solution*****
I have proven 100% that mine is problematic hardware . . . . . NOT software or kernel. For the time being my WiFi is back up & seemingly stable. I had to remove the back from the tablet for the fix. You have to be *extremely* careful, but it just snaps off with no screws. Lots of YouTube videos if you choose to attempt, but please don't say I didn't give you fair warning!
The reason I say partial solution is that I haven't pinpointed the exact location of the short. I am 99% sure it is somewhere on the extreme upper left hand corner as you face the front of the tablet. There are a couple of ribbon connectors in that area, and a few snap on type connectors that look like little motherboard chips. After gently poking & prodding the ribbons and disconnecting & reconnecting the snap connectors (being CAREFUL; I cannot stress this enough), my WiFi reappeared.
My final tip is to keep the screen on the page that shows the list of available networks. If you are having the same problem I was, this screen will just show "turning on" and nothing else for the WiFi. While poking around, I would occasionally see the list of networks pop up & then go back off. I finally hit whatever the magic spot is, and the networks held. Snapped the back cover on again, and I've been online for probably 4-5 days now without a single hiccup.
And before I get flamed, I know how dangerous it is to poke around with a powered, exposed tablet. There are probably certain points that could make connection and FRY the entire thing in an instant. I was just willing to take the risk as my tablet was useless without network capability. I had nothing to lose. I would recommend at least trying to poke & prod with the tablet OFF a few times to be safe, but I personally got tired of rebooting over & over & over & over. My luck sucks. With the tablet ON, I was at least able to monitor when something was happening.
Good luck if you attempt it!!

I bought my Note in March of this year, I started having the WiFi issue after the April firmware update. At first I would get the Connected to... message at random times, even though I had full signal strength. At the end of September, I started losing connection at random times and in the middle of October, I had to send it in to Best Buy's Geek Squad service to have them repair it. It is a hardware issue, as the no matter what firmware version I use, it will never connect to the router. I know it, Geek Squad is aware of it, as I have sent it in for repair twice so far. I would have to send it in a third time before they will think about replacing it with a new Note. I will admit, that before I updated it in May, I did root it, because I tried to remove the Business Week+ and New York Times apps, as I never used either one of them. I tried disabling them, only to have them reactivate and update themselves.
Damn, what I read here is not good news. My SM-P605's died yesterday.
With Tapatalk on my Galaxy Note 10.1 (2014)
Hardware issue for sure. Same problem with mine. Opened the back case, disconnected the upper right (as your looking at the screen) small ribbon, reconnected, and boom, perfect wifi once again!
The EZ Package Disabler app is fine for debloating rooted and non-rooted devices with Touchwiz roms. It uses Knox, so that mustn't be removed. The apps are still on the system partition, but are completely dead now. While other apps, especually for non-rooted devices kill the system apps during boit and try to prevent their restart. But during boot the whole stuff is active until the app kicks in, allowing the system apps to receive updates, communicate, spam free flash mem etc.
The app wirks the same way on my rooted P605 and unrooted S5. And gives a reason to buy Samsung stuff, unlike Touchwiz and its bloatware. As far as custom roms go, i found that of my old LG L9 much better. Even if the early roms were AOSP 4.0.4 based, then 4.1.3, they had already had the fresh & bright look & feel of the future Kitkat, and a few useful enhancements like an integrated backup tool, which was more simple, but for me as useful as TB.
As for the main problem here, i think using a case with a hardened backside, and not one if these with a big hole(though being better than nothing), prevents oroblens like battery, display and seemingly wifi connectors loosening. Or bad solder joints. The backplate of the note gives thru any pressure on the back, especially in the middle area. It then rests on the battery, metal shields, connectors and stuff. This seems to generate enough wear over time for problems. The same back plate on a much smaller device(my S5, but that has a subchassis covering the innards, too) would be much stiffer, and my 7" tablet has an aluminium unibody case, such trouble is unknown there.
Hi Gents..
same problem here... I used to own a SM-600 purchased in 2014 unfortunately I lost it... (the first tablet worked without any proble until I lost it...) than I managed to found the same modell brand new on amazon... it worked for 2 weeks and 2 days ago wifi died... but funny enough not straight away.... first couple time just switched off the wifi... I managed to switch simply back... next day it only worked if restarted the device... now factory reset nothing... If it is hardware related why worked 2 weeks witout any problem? If it is software related why not working after software reset? Only installed a few apps from the store.. the device did not overheated or physically damaged...
I have the exact same problem.
Since I bought this a long time ago, I have to pay for the repair. I just want to know if it is worth it. How much did it cost you (if you bothered)?
In my opinion it would be foolish to spend a dime to repair a 4 year old tablet. If the battery is original, it may well be near the end of its useful life as well. FWIW, I bought this tablet used about 8 months ago and have not experienced this wifi problem.
It's still so well equipped, that you can't simply replace with a modern entry level or midline tablet, but with a top of the line one, so a repair is well an option.
I just don't have a clue about the SoCs performance level. To which current ones it would equal and where things get better. I can only compare it to my similarly(Snapdragon 801) equipped phone and my cheap 7" tablet's quad core Mediatek SoC, and that is considerably worse, though being three years newer.

Any way to test if my NFC reader is working properly?

I think the NFC reader on my phone might not be working. I tried scanning some NFC toys on it, and no matter where I placed them all over the back and front of the phone, absolutely nothing happened. NFC IS on and enabled, but I get no response.
Is there any way I can check to see if the NFC hardware in my phone is working properly? Or has anyone else had this issue?
NFC is working usually but it does have a small zone where is working. Is the area of the headphone jack, in that small zone between the camera and headphone jack, maybe a little bit of center to the left.
I also use the NFC for various things and I discovered there is working good, the worst part is when you want to do payments to find where is working

You are not alone with this problem.
Check this thread: https://forum.xda-developers.com/htc-10/help/nfc-reading-cards-t3372168
For me it never worked, too. But I don't need it, so it's not that important for me.
I already sent it to repair. They replaced some parts and it worked one time for me, but never again.
Yeah, I was looking through that post, but it seemed inconclusive. I do need NFC, but really want to make sure if it's a hardware problem first before I send it in for repair. I am not sure how to properly restore everything to a new phone exactly like it was if I do. Which is why I wanted to know if there was any decent way to test it first. Maybe a place I can get a cheap NFC sticker or some app that can test the hardware or something?
The "hardware" will be another phone with NFC, and the sticker can be an electronic passport or a credit card with "contactless" "(paywave)" option.

Thanks for this I was moving my yubi key all over but somehow didn't discover this spot, but you're right it does work near the camera as you describe. Previously I thought it was my OS Lineage, or hardware.
cheers
