Took the time to do the NFC tag test again.

I did the same test. Took an NFC tag and dragged it across the back of the phone till it read the tag.

I've created an image to show where the strongest and weakest signals are on the phone.

[IMG="HTC 10 NFC Signal Strength"]http://i.imgur.com/3FNFn9v.jpg[/IMG]

As you can see, the strongest signal (in red) is right behind the front facing camera.

The moment I put the phone to the tag, it successfully recognized the tag within a second.

Towards the middle (the orange section above the rear facing camera), it took a couple of seconds for it to read the tag.

Also successfully read it on the first try.

The yellow section is the top part of the phone (holding the phone on a 90 degree angle to the tag)

It would only read the tag from the left to the middle of the phone. It would barely recognize the tag from the middle to the right, but was extremely rare and sporadic (and not even worth putting a colour to it).

It took a couple of tries to get it to read the tag (only because I had to line it up right). It would occasionally give me the Error Buzzing sound (recognizes a tag but is unable to read it) but after a few tries, it would successfully read the tag.

Compared to the last 2 handsets I had, this handset is a HUUUGGGEEEEEEEEE improvement, but on the grand scale of things (compared to the HTC M8 & Galaxy S7), I would still call it a weak technology on the HTC 10...... which is a shame considering it was released 2 months after the Samsung S7. This should have been more than enough time to test their phones and all it's features.

But, back to the topic at hand.

Grab an NFC tag and test it using this diagram. If you're getting similar results, then I'd say that is about as good as you will ever get with this phone.

If not, get it sent back to HTC for repair/replacement.

This was my report when I logged the fault :

"The NFC reader isn't reading properly. When using an NFC tag, it would only recognize a tag in a very small part of the phone and even then, it would give a buzzing sound indicating that it couldn't read the tag properly. When using NFC with another handset, it would fail to transfer any data between phones, when sending and receiving".

Hope that helps everyone here.

My results of testing with an NFC tag are the total opposite of yours: My "red area" is right above the rear camera LED, and my "yellow area" located at the opposite side of yours.

Can you confirm please?
[HTC 10 Questions & Answers] TRLOS:
Chong81:

Are you getting no reception behind the front facing camera ?

I tried it your way and can confirm that on my handset, I am getting absolutely NO NFC signal on top of the front facing camera. I have no idea why on your handset, the top (yellow area) coverage is the opposite to mine.

As for the back of the phone, my strongest signal is confirmed to be behind the front facing camera. The moment I put the phone to the tag, it recognizes it right away.

The reason why I put a medium signal above the rear camera (and slightly above the rear LED) is because it takes that fraction longer to recognize the NFC tag.

I should edit that picture though and bring those colours down slightly. The strongest signal seems to come from that plastic strip between the top and middle backing plates.
[HTC 10 Questions & Answers] chong81:
Yes, confirm no NFC reception behind the front facing camera. My red area is located at the plastic strip right above the rear camera LED/flash.

But I made a mistake about the top yellow area: my yellow area is at the same location as yours.

The SN of my set begins with FA64C, manufactured on 12 April 2016. What about yours?
[HTC 10 Questions & Answers] TRLOS:
How did you find the manufacturing date ?

[HTC 10 Questions & Answers] indie1982:
I made this video to demonstrate the problem to Jeff/@urbanstrata after talking on Twitter, heard nothing back though :(

[YOUTUBE]oaJiLtynUh8[/YOUTUBE]
[HTC 10 Questions & Answers] TRLOS:
Take it in for warranty.
[HTC 10 Questions & Answers] indie1982:
Think I'm going to have to, but it'll have to wait a few weeks as I've got a bit of travelling to do. Lots of people moaning at HTC_UK about their UK repairs/replacements taking up to 2 weeks at the moment too :(

It mostly reads passive NFC tags after a few tries, Android Pay works every time and the YubiKey has never made the 10 react at all, so strange!
[HTC 10 Questions & Answers] TRLOS:
Mine took just over 2 weeks to get back.

Good part was that it was a brand new replacement handset.

Like I stated earlier, It now does read tags (after a couple of tries), but compared to other NFC able phones, the HTC 10 is a piss poor quality.

As someone who uses NFC tags almost 3 times a day, every day...... it is a constant reminder at how stooged we got from HTC :(
[HTC 10 Questions & Answers] manikapo3:
not reading NFC HTC 10

I have tested the NFC cards on 2 HTC 10 devices and both devices didn't respond to the cards. I tried other cards as well but no luck. But i can transfer the contents from one HTC10 to other via NFC. don't know what is the issue.
[HTC 10 Questions & Answers] TRLOS:
Another one for warranty. lol
[HTC 10 Questions & Answers] Kenya.Chan:
More than HTC care to admit?

I sent mine in for warranty/repairs with VodafoneAU. Hopefully I'll be getting it back this week but I've done a few tests with display models around Sydney and it looks like the problem is pretty wide spread. I could only find one that worked perfectly every time. All others would be intermittent or non functional.
[HTC 10 Questions & Answers] TRLOS:
I presume VodafoneAU are getting a few of these phone calls now.

Did they go through a list of troubleshooting steps with you or did they just end up saying "send it in and we'll send it for repairs" ?
[HTC 10 Questions & Answers] HarpMonkey:
Not sure if anyone else has mentioned or experienced similar, but I had a play with getting my phone to recognise a few of my cards today...interestingly my amex cards read immediately, but mastercard is a lot more hit and miss. I assume the technology is pretty much the same - perhaps poor software coding of certain implementations?
[HTC 10 Questions & Answers] Kenya.Chan:
Nope, I explained to them the issue and did some test in front of them. Used my M8 as a comparison device to demonstrate that the 10 wasn't performing as expected.

At home I used the NFC TagInfo by NXP app to test and it looks like it can detect most tags but can't pick up the payload. It would pickup my Sony SRS-X2 speaker but wouldn't pair. All other powered devices work fine, eftpos terminals trigger android pay to pop up, android beam works perfectly every time... Un-powered devices like a nfc tag, Opal card (travel card), Yubikey NEO don't get picked up at all. I'm thinking this could be a combination of a software and hardware issue causing the payload to not be read completely or at all.
[HTC 10 Questions & Answers] WPtE:
I've contacted HTC 2 weeks ago about this issue, they advised me to reset to factory defaults.

As that didn't do anything they asked around within the organisation, despite me asking if they'd repair my phone, showed them this forum even.

Just yesterday I had enough of waiting and now they do want to repair the phone, because they haven't heard of this issue before.

So finally I might get a working phone in about 2 weeks!

Is there a way to do a proper backup of the phone, like an image, which I could restore later? Or doesn't that work with encryption.

My old m7 feels way easier with all of that stuff :)
[HTC 10 Questions & Answers] TRLOS:
This is a load of bull****. They most certainly have heard of this issue before because I contacted them as well with the same problem. On top of that, Vodafone also contacted them just before they accepted my phone for repairs.

If you have a custom ROM, flash TWRP into recovery and do a full backup.

Just don't forget to re-flash the original recovery on before you hand your phone in
[HTC 10 Questions & Answers] WPtE:
Yeah dunno, their service is not that good. Broken Dutch as well every now and then.

I don't have a custom rom so far, but I do have the bootloader unlocked. Is it still possible to do a backup then? Or will I have an encryption issue when transferring to a new phone? (I know I'm going a bit off topic)
[HTC 10 Questions & Answers] TRLOS:
You should be fine.

I unlocked my bootloader on day 1 of getting my phone. Rooted as well. Backup and recovery isn't an issue at all.

Go for backup. :)
[HTC 10 Questions & Answers] castano22:
Wish I wod have known about this before I got the phone.

Has anybody got it to work with yubikey neo?
[HTC 10 Questions & Answers] TRLOS:
I've been using my HTC10 for about a week and a bit and even though I previously said that the top of the phone had a medium signal, I've come to realize that it is actually the most reliable.

I say this because from the back of the phone, you have to find the right spot to place the phone, and being at the back, you can't exactly line it up properly first time, every time.

Using the top of the phone, I basically read the tag like a barcode, angling the phone at a 45 degree angle over the NFC tag. It also means I have to swipe across the tag slowly, but at least I can read it on a first attempt.

If you can't get your tag to work in a similar way, then I would say it's a warranty issue.

This issue is more hardware related than software.
[HTC 10 Questions & Answers] nikanor1122:
It's working ok on my htc 10 unlock ver. It took long time…

To find the right position, but when I found it . it's work even with Case on it and read immediately my train card (rav-kav in Israel) the position is in the upper side of the camera and the 3.5 plug
[HTC 10 Questions & Answers] nikanor1122:

[HTC 10 Questions & Answers] castano22:
The top didn't work for me until after I updated to 1.81. I'm guessing I was having software issues. Thanks for the tip!
[HTC 10 Questions & Answers] WPtE:
I've just installed 1.80.401.3 and suddenly the top of the device started working...

It's not super consistent, sometimes it takes some skill to place the phone correctly before it starts reading.

2 tags tend to get scanned over and over again, the nfc sound is played 3 times a second.

I still can't read my passport though. Honestly enough the m7 finds it a bit tricky as well, it doesn't always pick it up.

I've tried it so many times and now out of nowhere it's (kinda) fixed!

They're picking up my phone tomorrow for repair, I'm not sure they should now though.

I think I'm going to call htc tomorrow morning to see what they think.
[HTC 10 Questions & Answers] Haldi4803:
So..... i used my old Xperia Z, and NFC with Android Beam.

I can easily connect both phones, send from one to another.

But when i use my Xperia Z to scan some Metro cards it always works instantly. While my HTC10 does not recognize a single card.

So either A: The singal is way to weak. B: The software does not allow such things.
[HTC 10 Questions & Answers] Kenya.Chan:
So I went around Sydney testing display models using my Yubikey and it's starting to look like only Vodafone HTC 10's don't have fully functional NFC (here in Australia at least).

The ones from Telstra seem to be fine and read first go every time. I'm starting to think this is a firmware issue.
[HTC 10 Questions & Answers] wetxxx:
Which line of default.xml corresponding with dropdown menu?

I must change calculator to NFC icon.
[HTC 10 Questions & Answers] Elfmirth:
My NFC have just died, used to work.

I had it stock, NFC worked on FW 1.53

Rooted and installed 1.80.XXX.1 when that came out, and NFC still worked.

But after 1.80.XXX.3 it have justed died, I have gone back to complete stock with 1.80XXX.1 didn't work, OTA to .3 still doesn't work.

so I went though this thread, and tried all the diff things in the thread, at no luck.

So was thinking if it might be as OP said that there are some major issue with the NFC reader, or if it might be FW related.

either way it's really annoying, just got used to use the NFC reader to check some of my cards.

(On a side note, android beem still works though, mannaged to send files to my GFs Z5p)
[HTC 10 Questions & Answers] TRLOS:
You said Android Beam works. - Just to clarify, you are using the NFC to beam data/photos to another phone right ?

If that works, then we can assume that the NFC chip is turned on and working.

So what isn't working then ?

Are you trying to use it with a specific tag ?

Tag placement is also important. Putting it inside of EM field will wreak havoc on NFC tag (eg, on a speaker box or next to a speaker).
[HTC 10 Questions & Answers] Elfmirth:
I was trying to Read cards with nfc tags ex buss cards or coffie house cards, tags and a beam worked, but could not Read cards, no matter how i placed the cards.

But updated to a cfw with 1.90.xxx.5 tonight and now I can scan cards again ?
[HTC 10 Questions & Answers] chong81:
I have the same problem as you - can't read cards most of the time, but tags, Android Pay and Android Beam work consistently though sensitive to placement.

Great to hear your good news on the new firmware! [emoji2]
[HTC 10 Questions & Answers] bnn72:
Hello,

I received the 1.90.401.5 OTA update and it seems that it solved also my issue with reading of NFC cards and tags.
[HTC 10 Questions & Answers] wetxxx:
For me also was better but reading nfc symbols is 100% correct. Sometimes correct read sometimes doesn't.

Send by HTC 10
[HTC 10 Questions & Answers] Toneknows:
So I received my phone a few weeks ago and no matter what I did, I couldn't get the NFC icon to appear, also couldn't get the toggle to turn off, it just kept turning itself back on. .

After an hour online with their chat live support here is what they told me..

1. The icon won't appear if it is on.

This is because... Wait for it.... Htc 10 nfc only supports nfc for mobile pay and not anything else, so it may work or may not, but either way it's not supported.

2. No matter what I do I can't get it to toggle off, I turn it off, it turns right back on..

They said, well there is nothing we can do, you need to wait for an update that should fix it.

Obviously I lost me mind over this and said that this was completely unacceptable that a brand new phone doesn't perform like it should and their only answer is wait and see....

Love the phone.

Had the M9 last year, really liked it too.

Guess I wait.
[HTC 10 Questions & Answers] Haldi4803:
Lol, that can't be true.

That has to be the answer from the Support, what they tell all the people that call and ask for help.

That's in no way the product desciption of the NFC functionallity. That would be Insane.
[HTC 10 Questions & Answers] Toneknows:
I actually took screens shots of the chat because I couldn't believe what I was being told. When I get in front of my computer in will post them (need to black out some personal info).

I did reach back out to them and got someone else on the chat and they were going down the same path until I informed them that their website states that NFC is fully functional and not just for payments.

They finally relented. . Solution is to send my phone in for repair, they refuse to send me a replacement even though it's only a few weeks old (claim they don't have new replacements)..

This will be my last HTC.
[HTC 10 Questions & Answers] TRLOS:
Thats not right. I would go back to the store (within 7 days) and demand a replacement. If they don't I would go to your telecommunications Ombudsman (or whatever your guys call it) and put a massive complaint in.
[HTC 10 Questions & Answers] chong81:
Have you tried a factory reset?
[HTC 10 Questions & Answers] Dakhan21:
Still nothing

Now I have 1.90.401.5 build, faster recognising, but still issues. Thanks

I talk with support but now they are gonna replace the NFC chip, that sounds like I pay a full price for a refurbished phone. :( , HTC 10 is almost unrepairable.
[HTC 10 Questions & Answers] steno66:
Same problem with 1.90.401.5 when I put Nfc near to back or front camera, phone make a sound but nothing works. With software Nfc tool I'm not able to write the tag. With banking app my phone don't see the Nfc card for authentication.
[HTC 10 Questions & Answers] Kenya.Chan:
On my 3rd phone with Vodafone AU and still don't have one with fully functional NFC. They're sending me a 4th one but I'm not keeping my hopes up.

My test of the display models in Telstra show that they work perfectly fine. If this 4th device doesn't work, I'll be jumping ship.
[HTC 10 Questions & Answers] chong81:
Which firmware version?
[HTC 10 Questions & Answers] TRLOS:
Ditto. Im on my 3rd handset as well.

Although the NFC isn't too bad. It's not great, but not too bad

Phone is back in for repairs though. Wouldn't update
[HTC 10 Questions & Answers] slithertooth:
Just updated to 1.92 and my NFC still isn't reading cards. What's frustrating is it USED to read them up till 1.80 so I'm convinced it's only a software issue.
[HTC 10 Questions & Answers] stretchnz:
This is interesting, just came up on the thread by chance.

At first I thought my phone must be fine, as I use my phone to pay for groceries every time. The terminals have paywave as we call it here (NZ) and it works flawlessly from my TW HTC 10.

That is from day dot, original software version, through all updates etc (but have not tested since today getting 1.92 update).

However I just tried to read the NFC in my bus card and no dice, beeps like mad like others in this thread describe, can not get a successful read on it.

So if I understand correctly?;

- NFC tags / cards are seemingly the issue with problematic phones?

- EFTPOS etc terminals such as at super markets are NOT a problem?

My phone was parallel imported and I dare not wonder what warranty dramas / delays I would have to go through with that.

But only use it for paywave which works so not a real issue for me, just interested to see there is an issue!
[HTC 10 Questions & Answers] castano22:
Have you tried reading the card from the top of the device? Mine tends to read my Yubikey from the top of the phone near the headphone jack. Though I occasionaly have to turn off and on my nfc/device for it to work at times
[HTC 10 Questions & Answers] spamdie:
I rarely used NFC to begin with but had fun with it on older HTC models.

My HTC 10 will continually read a NFC Chip till no end. It will just read and never stop. I could set it to go to a url and stick it on my phone and a minute later 1000 instances of the web browser will be kicked in.

So I talked to HTC support and the answer they gave to me was. "NFC is ONLY for Payments and no other use is supported". So they washed their hands of this.
[HTC 10 Questions & Answers] TRLOS:
Actually, that is incorrect. I would go back to where you bought the phone from and put a warranty claim in.
[HTC 10 Questions & Answers] Gustiyudha:
Try this guys

I think i found solution for this issue, you can try to enable developer option, i have same nfc problem same with all of you but since i enable developer option without changing the setting, my nfc can read nfc card without any problem, so maybe this can be work for you too,
[HTC 10 Questions & Answers] Haldi4803:
I've had Dev Options activated All The time. Every time i wipe my phone that's One of the First things i reactivate ^^

So that's probably not gonna help.

But it's worth a try!
[HTC 10 Questions & Answers] TRLOS:
It doesn't make a difference.

I've had Developer Options (USB Debugging) enabled since day 1 of my phone and it doesn't do anything different.

I even tried enabling High Performance Mode (hoping it would boost power to the NFC reader) and even that had no effect.

In your case, I would probably call that a placebo effect. Or perhaps you're holding your phone differently when you try reading NFC tags.

Only way I can get an accurate read with my phone is to read it from the top and slide it across the tag., and even then its a 50/50
[HTC 10 Questions & Answers] Gustiyudha:
Actually the card position is horizontal, just put the card on back camera, my phone will read it, but it's not directly read need avarage 5 second to recognize the card.

I think this is because in the option you can only choose nfc on/off. If i compare with android phone for nfc they provide two option, nfc on/off & android beam on/off.

So in HTC 10 will firstly recognize your card as android beam, so maybe thats why it can not directly read the card
[HTC 10 Questions & Answers] Haldi4803:

[HTC 10 Questions & Answers] mhajii210:
Guys I have found that sometimes at certain pay terminals (like Coffee Bean for example), I have to toggle NFC off and then back on in order for the terminal and the phone to communicate. It works flawlessly each and every time at Panera Bread without having to do this. I just got the phone a week ago. Should I be worried about a hardware problem with the phone or do you guys think it's not the phone since it works perfectly at Panera Bread? It also works fine when I touch the phone against another NFC equipped Android phone.
[HTC 10 Questions & Answers] ceeceevee:
Mine works with only one specific card...

Well, I just came across this thread after realizing this morning that my phone couldn't read my Opal transport card nor any of my PayWave/PayPass-enabled credit cards. Actually, tha'ts incorrect: it can read one of my cards (a bank debit card) but none of the others. Works every time too, if I hold in FRONT of the front speaker. No scan at all if I do it from anywhere else, including the back of the phone.

The fact that it can pick up one specific card makes me wonder if it's to do with NFC compaibility between certain items/devices. Also, the particular placing seems to indicate a really weak/narrow range, possibly due to an incorrect power setting?

I'm currently updating to the latest available build (Australian-stock, unlocked phone), 1.95.something, so we'll see what happens then. I've had the phone for 3 weeks now and, based on other people's experiences, I'm not convinced a return/exchange would fix things...

---------- Post added at 01:12 AM ---------- Previous post was at 12:18 AM ----------

Update: I've updated to 1.95.710.3, no luck. I've enabled Android Pay and I'll try using it later today to see if there's a difference between passive NFC cards and active NFC devices...
[HTC 10 Questions & Answers] Haldi4803:
There is! Quite easy to test with 2 android devices and NFC Beam.

You say one of the card works? Could you use NFC Tools to find out which format/tag this card is using?
[HTC 10 Questions & Answers] ceeceevee:
Sure. According to NFC Tools:

Tag type: ISO 14443-4 IBM JCOP41 (Classic) 1K
[HTC 10 Questions & Answers] ceeceevee:
Quick update: I tested Android beam last night for both sending and receiving files and it worked fine holding the phones against each other (facing outwards) so I'm hopeful Android Pay will still work and that the issue is limited to NFC cards.

For the record, I tried scanning all my cards with my old nexus 5 (still a cracking phone, btw) and it worked perfectly every time, in contrast to the HTC 10 which could only detect one out of 5 cards, grumpf...
[HTC 10 Questions & Answers] ChronoReverse:
At least for my, NFC payment has worked every time on terminals that supported it up here in Canada. Quite fun actually.
