Hey guys, I recently flashed the factory Lollipop image from my Nexus 5 (LRX210) and everything was running great.
Not soon after I set up my Tap & Pay, I realized that I couldn't complete my purchases. I thought maybe it was my Wallet app, or something was wrong with the priority of the wallet app, but that wasn't that case.
I tried beaming content via NFC to many other androids, but it was like my NFC card was dead. I didn't get any feedback from other devices, and even when I scanned a NFC tag it didn't react.
My NFC card was working fine before I went to 5.0, does anyone else have this problem? Really hoping I can get some info about it.
Thanks.
Bump :/

Try pressing down on the back cover where the qi and NFC connectors are. If that doesn't work then you'll have to open it up or RMA.

I was just reading up on it. Before I upgraded I opened up the back cover to show my friend the internals, then I snapped the cover back on (without pushing the back cover). A week past, then I updated to Lollipop. Another week has past since I upgraded and I just now realized the NFC wasn't working. I got my friend to let me use his wireless charger, and it worked fine. I also tried pushing the back in to hear that extra snap, but nothing has seemed to work.
Edit: I also flashed the factory image for KitKat, and NFC still does not work.
Perhaps I should be more detailed when I say "not working." The NFC does indeed recognize NFC tags and other enabled devices, however it does not vibrate like it should, or work like it should. I have many NFC tags that I bought and were working just fine. I tried them out 1 by 1 with my Nexus, and every time I scanned 1, a white screen would flash for a very brief moment, as if it was a windows opening and then closing before the animation finished. I used the NFC Tools app, and it recognizes the tags, but it can't read, write, lock, or do anything to them. I downloaded an app called NFCSniffer, and I get feedback from tags as well. But it seems as though my NFC chip is not working correctly ever since I opened the back. I'm really confused about this whole situation and wish I hadn't even opened the thing.

Weird. In all the cases I know of, the NFC chip is either completely dead or just not connected properly. Try opening it up and putting it together again. If that doesn't help then I guess you'll have to replace the chip.

Alrighty, I'll let you know how it goes.
Thanks for the responses.
Alright well I guess that didn't work... Can you recommend a good place to buy a chip?

Not sure where exactly one would find them. Just have to search for one, or if they don't exist then I guess you'll have to send it to LG for repair.
Alright, thanks for the info.
Hi guys,
So the other day, phone was working fine. All of a sudden, it comes up saying 'No SIM Found'. The phone is pristine, have never dropped it, not a scratch on it. Have had the SIM replaced, no dice, works fine in my Note 4 though... Also tried the whole 'jam a little bit of cardboard in' caper, in case the SIM wasn't making contact with connectors. Have flashed stock firmware on that too, nothing...
I've read a little on region locking and the like but it doesn't seem to be the case - though I'd love to hear if anyone has a potential fix associated with this so I can try it.
Anyway, long story short, has anyone come across this and has anyone fixed it? I took it to Samsung and they say that they have to replace the mainboard of the phone...
Thanks in advance guys.
Anyone?
SIMs can suddenly fail. Have you tried getting a new one?

Try installing a custom rom. Your only option left without sending it to samsung
Did you found any solution to this?
Hi,
I am wondering if there ever was resolution to this issue. I am running into same exact problem and tried most of general items, except re/soldering the sim reader again
I took it to authorised Samsung repair shop in Croatia for sim reader replacement, and they replaced whole motherboard in factory warranty, even thou I told them I bought the phone over ads and have no warranty.
Has anyone got NFC to work?
You have an option of choosing NFC secuity chip by choosing kne of the sim slots
But it does not read any nfc tags

I'll admit I had a time trying to get nfc to work. Just sending a picture to my wife (who also has the Mate 8), was a task. I finally got it to work when we took our cases off.

First i read "clothes" then "cases" ... :laugh:
lol, it just needed a little LUV baby!
have you found the solution? mine also not working and been trying to reset as well... this is a nightmare!
I had my NFC work as mobile payment. It works smoothly.
AL10 reflashed to L29
NFC doesnt work, i try to read card, on oher phone works
kangvip b170
On my AL10 NFC works. I transferred a video I had taken to a friends Samsung phone through NFC and it worked fine. I was running KangVIP B168 at the time but NFC should work on stock as well.

I tried this with another Mate 8, made the 2 Mate 8 "kiss" close to where the camera is. The other phone recognized a tag which it could not read (My Mate 8). That was L29C185B560. I just updated mine to L29C636B563... I tried to NFC with a Windows Phone. No luck.
Pretty pissed now!
I also have a problem with NFC on my Mate 8.
Current firmware L29C636B563, previous firmware tested on L29C636B321 (and maybe L29C636B330)
First off, I was testing this with an LG Washer / Dryer with the "Tag On" logo. The LG Application could not detect the NFC so I will assume the problem is with the phone? Where exactly is this NFC strip they are talking about? No, even after updating to L29C636B563 Nougat OTA Push Update, my Mate 8 will still not work with LG Tag On.
So, I got curious as to whether or not NFC was working to begin with. I live in Canada. It is a very *backwards* country and NFC applications are few and not mainstream. Apple Pay just got introduced... and Android Pay is not even available for download... so... I never really had any use of NFC at all.
Anyway, I have another Mate 8 (not mine). It recently got an OTA push, L29C185B560. At that time, my Mate 8 was still at L29C636B321.
We tried Android Beam... I guess the instruction was to bring the phone close together (in this case - back to back) and both phones will detect each other... then you can tap content to the other phone...
Well... the L29C185B560 (let's call this C185 for short) made a sound and it picked up a tag, but that tag was empty... ?? My phone, the L29C636B321 (let's call this C636 for short) did not do anything at all... it just stared and stared in outerspace....
I also tried to "Share" and then pick "Huawei Beam" and of course, nothing happened between the 2 phones....
I was suddenly discouraged... eeeks! No NFC? I thought this phone was the *super* phone... time to shop for another phone.
Just last week, my C636 got its first OTA update... uhm... only after downloading Firmware Finder... maybe it did something to the settings to correct it...
So, it got updated to C636B330 first, then 2 days later, C636B563 arrived. Yay... Nougat! What bugs are there?
Just 2 days ago, I tried to Beam with a Samsung Galaxy S4. No luck there...
So just this weekend, I tried Beam again... first, just putting the phone together... no luck.
Then, I thought... uhm... so this time, I put the phones together, back to back and then picked a photo on my phone, "Share" and "Huawei Beam".... surprise, surprise... I heard a tone.... I angled my head and saw that my phone recognized a device and I tapped and I guess the other phone, the C185 didn't need to accept the beam, it was already downloading the photo...
So I tried the LG Tag On again... no luck...
Then. I got home and downloaded apps to read my chip enabled Canadian passport (inside and outside the covers) and my Paypass enabled credit card... No... none of the apps detected anything.
To my understanding NFC will "communicate" once detected. No further action. In the experience with Huawei Beam... it seems that an "action" has to be triggered for NFC to activate? Maybe I am wrong and have been wrong all this time?
So, does "reading" an NFC tag also require an action?
What else is broken?
I found some documentation on Huawei Mate 8 NFC. Maybe someone with more experience will be able to explain this occurrence way better? Give us more insight and get it working?
I just bought 10 NFC Tag stickers on eBay, let's see late on if the phone actually reads it....
Thank you for this. I had sworn my NFC was dead, then I took the extra step you mentioned of trying to send a picture using Beam, and that appears to have woken the NFC chip up. I can't believe it's working fine now.
Cheers!

Actually, never mind. It's dead again. I have no idea what I did to make it work for a short while,
but now it won't read my cards anymore. (sigh)

Repair
Same case but i have found the reason.
The nfc antenna is embedded in to top side of back cover.
It's connected not with flex cable, but with spring contacts
2 screws on bottom
open carefully (fingerprint scanner on cover is connected with flexible cable)
adjust spring contacts
clean contacts and contact pads on cover with alcohol or ...
that's all
now it works
Hello,
I have an issue with NFC on my Mate 8. Indeed, I tried to read the informations of a NFC credit card and it's very very very hard to detect the card (I have to push the card on the NFC antenna with my fingers and trying multiple positions before success). I have no issue with the same card and my old Nexus 5.
So NFC is working but it's like the NFC antenna power is too low.
I'm on L29C432B560 (EMUI 5, Nougat), never unlocked booterloader, never tried NFC on EMUI 4 and 4.1.
Any way to fix this?
My 2 years warranty will expire in one month so if it's an hardware issue I can always use it.

Is is possible to draw a simple photo of the angle & location? What did you mean by "push the card on the NFC antenna with my fingers?"

Here's my sad experience:

NFC antenna is placed on upper side of the back - above the camera. Use that area to touch when using NFC for file transfer, not the whole back of the phone.

OK...
I tried back-to-back, 'top to top'... Is there a specific angle? Maybe someone who has had success can draw a simple picture?
I have an L29C636B321 (recently updgraded to L29C636B330) ~ when 'back-to-backed' with another Mate 8 L29C185B560 (after many trials) - the L29C185560 seems to activate it's NFC as seeing a 'Tag' without information. My phone, the L29C636B330 did not do anything... nada... really, nothing.
It is becoming annoying now. I've had this phone for close to a year but never thought of using NFC until I bought an LG Washer with "Tag On". Of course, my Mate 8 was not able to read the Tag?? So I had to test.
Today, my L29C636B330 was officially upgraded to L29C636B561 Nougat. NFC and Huawei Beam turned on off course...
NFC back-to-back with my Lumia 1520 Windows Phone... not working.
NFC many positions with a Samsung Galaxy S4 (SBeam/NFC On) - nothing. Sharing a photo...
So is this phone broken from the get go?
It the firmware responsible for this?
Is there a hardware malfunction?
How do I get NFC to work???
When I used an App to detect NFC. It says, NFC is enabled but "no tag detected"?
HELP!!!!

Hi,
I recently bought Mate 8 and I got the NFC issue as you describe.
I came to my mind when reading your post that you said "push the card on...".
Here is my solution:
1. Disassemble the phone, two screw off and open the rear cover.
2. You can see metal spring contacts on the top of the phone to connect the main board to the rear cover.
3. Raise the metal contacts to easily touch the rea cover.
4. Assemble back the rear cover.
Thanks
I enabled Google Pay on my Pixel 7 Pro then enabled it on my Pixel Watch. Then I was at a shop and tried to pay with my phone and realized there is no credit card registered. I think the moment I added the card to my Pixel Watch it also disabled it from my phone. Is there no way to have Google Pay active on both the phone and smartwatch at the same time?
Hmm you're right, I had done the same but not noticed that it's gone from my phone. Seems a bit daft.
/Edit, I'm wrong wallet is working on both watch and phone.
working fine on both here...
