    I watched one of those tear down videos on the Nokia 8. There is a WiFi chip to the left of the selfie camera. If you plonk this part of the phone in the middle of a point of sale device's screen, holding phone at 45 degrees, it seems to work every time. This agrees with my passport reading experiment.

    Here's a couple of thoughts I've had having read about various problems with NFC.
    There seems to be two areas associated with the NFC system. Firstly, a passive receiver area (location pinpointed by Mark Coly above) used by Android Pay; this chip is powered by RF from the point of sale.
    Secondly, an active area, that generates it's own RF signal allowing you to read/write your own NFC tags, situated under the middle of the camera assembly (over the dividing line and Zeiss logo seems to be the hot area, from testing here).
    I haven't used Android Pay with this phone yet, so I'm theorising on what I've read from others.

    I've found NFC tags worked fine here, although they took a noticeable few seconds to read, but I do have a 3mm thick case.

    Alas since an Oreo update yesterday, the NFC (under the camera) seems to no longer work. Don't know about Android Pay.

    NFC not working after Oreo update

    NFC had stopped working completely for me after the Oreo upgrade. I wiped Google Play cache and data and rebooted; this revived and restored NFC to working order.

    Spoke too soon, while reading NFC tags worked fine with Nougat, I've found I now have to switch NFC off and back on again to read a tag, since the Oreo update. Similar to reports by others.

    I have the same problem. I have been able to read one of my NFC cards just a few times. Switching NFC off/on helped once, but doesn't work anymore. Never tried with Nougat, only tested with Oreo beta and Oreo official.


    Hopefully this is a software issue that will be fixed quickly!

    This might help, it seems to have got my NFC going again here, at least it has worked as expected since yesterday without having to deactivate/reactivate NFC:
    In Settings/Apps and Notifications, go into your list of apps. Use the menu there to ensure "show system apps" is checked. Now in your app list you'll find "NFC Service". Tap the service and then tap Storage, from there you can clear cache and data.

    @Seány Good idea. I tested clearing the data of the NFC service, and was able read some NFC cards a few times. I noticed that the card should not touch the phone, and having it close to the camera at an angle seems to be the best way to get it working. But after about five times of reading cards successfully, I'm back where I started. I'm not able to read the NFC cards.

    Yeah mine has started acting up again too, and I'm back to toggling NFC off/on to get it to read. Guess it's going to take a software update to fix it.

     Same here, NFC is back working when i disable and enable it again.

  • I haven't had a chance to test this but Oreo has quite an aggressive app optimiser which basically puts stuff to sleep until you go to use it, if you go into settings battery and then click the 3 dots at the top right hand side you should be able to see battery optimisation. Scroll down and look for the NFC service, try changing this to do not optimise and see if it helps. You have to do this if you install a 3rd party email or messenger app to ensure you get all your messages so I'm wondering if the same thing has happened and Nokia have forgotten to white list this service by default.

    The NFC service wasn't whitelisted. Changed this, but doesn't seem to help.

  • That is a shame, I wonder if their is any other service to do with NFC that isn't obvious that needs whitelisting then. I noticed something called tags in the list, not sure if that could be anything to do with NFC, I can't see anything else obvious.

     I have the same problem too.


    And I tested my Nokia 8 then found when the NFC function will fail.

    If you use the fingerprint to unlock the phone, the NFC function will not work until you disable and enable it in setting.But if you use the other method to unlock it(e.g. password), NFC will work again.


    I'm very confused. I don't know it is a bug or it is the special case for my phone.

    Since the update to Oreo I have to hit airplane button twice before NFC will work. I usually unlock phone with fingerprint so will try unlocking with PIN next time based on the above post.
  • CY Luk CY Luk

    I try to hit airplane button twice just now and the NFC work too.So I think it maybe a software issue.

  • After some testing today I can confirm that NFC works better if you don't unlock the phone with fingerprints. I used to restart NFC to get it to work now it seems I only need to lock the phone and don't unlock it with fingerprint.
    Must be a software bug, please fix.

    I have difficulty to read passive NFC card by my Nokia 8. I tried to read my Octopus (contactless stored value smart card use in Hong Kong) with it's official app but 1-2 successful read after tried for long time. It's seem that the phone can detect my card but no able to complete the progress. I tried to read the same card using same app on my old Nexus 5 and always success to read the card.


    I also tried to read my Sucia (which use in Japan), sadly, this time I had 0 success after tried for not less than 15 minutes.


    I still don't have time to try Android pay.

  • For me, Android Pay and other banks apps now works correct. You have to restart NFC (switching off and then turning on).

    The position how you put the phone over the card or NFC is the key for working. NFC sweet spot is on the top of the phone (if you see the phone in lighted area you will notice that there is a rubber area). Put you phone touching the card or the NFC point with this area. The angle formed between mobile and phone has to be over 30 degrees. For me it was the key. Now it always works perfect.

    I link an image that a partner share with me in XDA with the correct way for works with NFC (remember reset NFC connection!)

    Just tested Android Pay today and it work properly (expect I need to  switching NFC off and then turning on). For NFC card, I still can read them properly.

  • My NFC works very rarely. I Donot know what is the problem. Is it something about the software or the hardware??!!!
  • I can also confirm that with Android 8.0 Oreo you need to switch off NFC and switch it on again (if the phone has gone into sleep since you last used NFC).


    The NFC antenna needs to be small to fit the nonmetallic area around the back camera. This makes the alignment with NFC a bit tricky but it is still a useful function. However, I miss the possibility to turn NFC on and off in the top activity field.


    It would be nice if someone from Nokia/HMD could confirm that they register software bugs reported here so they can fix them in a future software upgrade.


  • From what I've read Google in their wisdom took the NFC tile out of the pull down menu "for security". You can get 3rd party apps to add more tiles to the top but it's annoying.
    I think the NFC issues are software as it seems to work fine most of the time once you know the trick of turning it on/off and then turning on screen. As well as knowing how to hold it

    Would be nice if they had a bug report section in the Support App instead of contacting customer support as they are worse than useless in general

    I've noticed some odd behaviour with NFC on Oreo when trying to use Android Pay. I've managed to use it alright with Nougat though I've only used Android Pay a handful of times.


    So, I've been playing about with NFC a bit and have confirmed the following behaviour on two phones:-


    Prequesites

    - Updated to Android Oreo (8.0.0), security patch level 1 December 2017

    - Start with NFC turned on

    - Fingerprint lock configured with PIN

    - Behaviour observed with glance either on or off

    - Testing on an NFC enabled card with "NFC Reader" by Adam Nyback, downloading from Google Playstore


    NFC does not work

    - Start with screen on

    - Lock phone with power button

    - Screen should either display glance or be turned off

    - Unlock with fingerprint reader

    - Attempt to read NFC tag, NFC will not work


    NFC does work

    - Start with screen on

    - Lock phone with power button

    - Screen should either display glance or be turned off

    - Wake screen with power button or double tap on screen (if gesture is configured)

    - Unlock with fingerprint reader

    - Attempt to read NFC tag, NFC will work


    Note the additional step of waking the phone before unlocking seems to be the key. Once the phone has been unlocked in this way the NFC reader has worked consistently for me (tried 30 - 40 times over a short period of time before I got bored).


    If anyone else could confirm this on their handset then maybe a moderator could forward this as a bug report.

  • I can verify the above. I'm able to test with an iPhone, as every Android with Android Pay set up will light up an iPhone and open up Wallet if it is pressed next to it with the Android device unlocked. This has been true of every single other Android device I have used since I adopted Android Pay.

    From a purely unlocked Nokia 8, if I press it against a locked iPhone, the iPhone screen stays off. On other Androids I would see the Wallet screen at this point.

    If I lock the Nokia 8, hold it back to back with the iPhone and unlock the device with my fingerprint, again the iPhone does nothing.

    If I lock the Nokia 8, hold it back to back with the iPhone, tap the power button and THEN use the fingerprint scanner, Wallet opens up on the iPhone.

    If I lock the Nokia 8, hold it back to back with the iPhone, double tap to wake and THEN use the fingerprint scanner, Wallet opens up on the iPhone.

    So there is definitely a software bug and there is no issue with the strength of placement of the NFC, nor any need to hold the phone in a particularly quirky manner.

    At least I now know what I need to do to make it work every time.
  • user1515274512611, you're a genius! That trick of waking the screen and only then fingerprint unlocking works! Not being able to reliably use Android Pay has been frustrating me for months since I got the Nokia 8. This isn't the perfect solution (i.e. Nokia really need to fix this properly), but it's still a workable stop-gap.


    I feel like something as specific as the method you found really should help Nokia find the problem... Fingers crossed.

    NFC works again in Oreo 8.1 Beta. I can finally read my Octopus Cards my balance.

     Great news jeff, i'll try it out asap!

  • A big thanks to everyone who posted about finding NFC at top of phone- I now have no problems using android pay

  •  Anyone using SEQR with 8.1 beta?

    After installing the 8.1 beta Tap&Pay in SEQR that uses NFC become useless.

    Is Android Pay working with 8.1 beta? (unfortunately not available in Sweden)

  • I was trying to use the NFC to top up my travel card and found it difficult at 1st, I find that if you hold phone at an angle but actually tap the top of the phone against the card or NFC device it works every time.
