Is wireless charging dependent on NFC functionality? I've read through any thread on the topic I could find and haven't seen this directly discussed. I'm running Illusion 5.0.2, and like every other rom I've tried or reviewed, NFC is quirky.
I bought an Anker charging pad and an NFC sticker for my cover. It kinda works for about 10 seconds, and then it stops charging. It happens every time no matter how the phone is sitting or if I have my thin case on it. This tells me I installed the sticker correctly and the pad works, but something is jacking up the charge. This is more about my curiosity than a need. I don't know how much I'd use it anyway. While plugged in and charging, I can use my phone. Not so much when it's sitting on a pad. Not very functional, IMO.
Still, I'd like to know why this isn't working. Does this all come down to NFC functionality?
I don't think NFC has anything to do with wireless charging. Wireless charging doesn't work on any AOSP roms that I have tried for this phone. I would think the reason it's not working is either it hasn't been implemented in CM yet or maybe it requires oem framework, which in this case, it may never work on AOSP. Kinda like WiFi calling will prolly never work on AOSP.

Well, that's interesting. Fortunately, as I said, I don't think it's very convenient. Thanks for the feedback.

So, I was just reading on here about the mysterious four prongs under the camera behind the battery door and someone mentioned something about possibly being able to support NFC with a replacement battery door. So, I got to thinking and googled about it and I came across this over at Android Central:
http://www.androidcentral.com/htcs-ceo-says-lte-phones-coming-2011-will-support-nfc-too
I know its from Dec. but it still caught my eye.
So, does anyone know or think that it is possible to get NFC support on the TB with a software upgrade to 2.3 and a new battery door with the sensor?
Pretty sure the prongs are for inductive charging.

I agree with this...
I also agree; however, I'm unsure as to why there are 4 prongs for that... But well maybe there is some factor to inductive charging I'm missing. But I seriously doubt NFC will be supported regardless.

I just don't see the point in it. You wouldn't be able to really use it anywhere yet. Inductive charging would be neat if the back piece isn't any bigger than it currently is, or isn't much bigger I should say.
Well, looks like it is for the wireless charging:
http://www.verizonwireless.com/b2c/store/accessory?&action=accessoryDetails&accessoryId=47423
I would still like to have NFC support. Oh well. have to wait another 2yrs.
It can be done. But it's unlikely.
NFC can be super thin and connect via bluetooth. If it's built into the case and receives its power via the prongs, it could work. The prongs can be just for power purposes. Transfer of data from the device would work over BT.
I know wireless charging is possible via the Touchstone method if I'm not mistaken, but if I recall, you're stuck with using that and only that. Is there a way to hack in wireless charging on the Note 2 with any charging pad such as that Fatboy pillow or the Nokia pads or anything with the Qi standard?
Also, can someone take a picture of the location of the wireless pins on the phone. I hear they're covered, and I just would like to see the back of the device.
Thanks in advance!
I am wondering the same thing. This is the first video I have seen which at least means we dont have to replace the usb charging board. You can see where he solders the leads. He says its a Qi back in the comments.

No, you wouldn't be stuck with charging only through the touchstone. I did this mod on my galaxy nexus and didn't have that limitation. I love the touchstone and I'm looking to find confirmation that someone has done this mod on the Verizon Note2...I see info about all the other versions but not this one. I'm assuming it's going to be similar to the Sprint version mod but don't know for sure. Please, if anyone has info on this mod for the Verizon Note2, respond.

Well I'm intrigued. I own the Verizon note 2, 2 HP touchpads, and 4 touchstone chargers. I love being able to drop the touchpad into the wireless charger and letting it go. To have this functionality with the note 2 would be to cool. I also have a fair amount of electronics knowledge. I'm pretty certain that once retrofitted, a device set up for wireless charging would work with any wireless charger as the principals of charging are all the same as I understand it.
One question that comes to mind.. is there really any difference in the make up of the note 2 circuit board between providers other than maybe the radio circuitry? If not then there isn't any reason why the mod shown in the video shouldn't work. Over the next couple of days I'll check into this and report my findings.
Anyone thinking about getting this?

That would be nice but we don't have contacts to line that up with... We technically do have the hardware their but I have heard a few horror stories about people not being careful and screwing up their phone trying to do the mod. I had wireless charging on my S3 but I think I'm gonna hold out on the Note 2 this time around...
Don't open case or you lose LTE/GPS

So I ended up buying the Qi charger on ebay along with a new chassis back (it was for the GSM variant) with the intentions of swapping backs and then having the holes to put the qi charger through. After MUCH hacking of the back, it worked, however I lost GPS, and 4G LTE. The chassis is just too different to work correctly.
I then put the Verizon chassis back, back on and used some copper tape to get the contacts to touch without the holes. Everything worked properly, but still no GPS or LTE.
I took it apart thinking I broke maybe one of the pins that use the chassis back as the antenna -still nothing. So moral of the story, don't take the chassis back off or the phone will be half of one. Its been about 4 days and going to various places in SF to see if LTE would come back on, but no dice.
Going to return this phone since its now broke (still 30 days) and next I will try and use the copper tape to put behind the actual battery contacts and NOT open the case at all.
Really wish VZ didn't take away this capability, as I already invested in the wireless charging stuff for my HTC Thunderbolt. Have a S3 and that works perfectly fine since the holes/pins are there.

You must have damaged something. You can take the back off without destroying anything - in fact you have to when you first get the phone since the battery doesn't come preinstalled.
Edit: never mind, didn't misread your post. But people have removed the chassis too - you still must have damaged it somehow.

Ya I must have, everything looked fine, but ya, something happened and I couldn't get it to get back to 4G. Went back to Verizon today and got a new one. I want to try and see if I can just hook directly to the battery terminals... need to get my ohm meter out.
I did it to mine took about a hour be careful and gentle minimum force is needed follow the YouTube video and use the proper tools

wow, you break the phone and then go and exchange it.
And they say personal responsibility is dead in this country...
I have had my G3 for two weeks now and am very happy with it. I dumped my Droid 3, so as you can imagine, it's a huge leap in technology and power to go from the Droid 3 to a G3. I decided I wanted to start doing wireless charging as I saw several others in other forums talking about their shells getting cracked or damaged from excessive force needed to insert the usb cable to charge the phone. It does seem like it could eventually lead to some heavy wear and tear.
So I did some research and a lot of reading, and purchased the following charger and back cover and I can't get wireless charging to work at all. The reviews on the charger appear to be very positive and according to the description on EBAY, the back cover will work on the Verizon G3. The pins appear to line up correctly and I have tried moving the phone all over the mat but no luck. Could one of the apps I have frozen in Titanium Backup be preventing this from working? I basically only froze the crapware stuff. Is there a setting somewhere that needs to be configured? I have an email out to the EBAY person I bought the cover from but have not gotten a response yet. Ideas? Suggestions?

Does your new cover have 4 pins space correctly? I know in the past, some vendors from ebay were sending out only the NFC cases on accident and calling them Qi covers.
The charger you got is a knock off of the TYLT charger, so it could possibly be something with that charger too. If you have a Verizon store near by, Id go down and see if they ahve any Qi chargers setup. Each one I have gone into always had at least one so I could test if my things were working.
The new back cover definitely has 4 pins and from the best I can tell, they match up. I will definitely try your Verizon store idea when i can find a store.

hi, I have European version D620 for my girlfriend, incl. a NFC chip, attached to the inside of the back cover. So it has 2 contacts in the phone that connect to that. We do not use NFC at this point, would prefer Qi Wireless charging... would putting in a Qi wireless charger foil connected to those 2 contacts instead of the NFC chip do the trick? Would it be something LG would have need to have built in, or would it be recognized by Android? This D620 has Android 4.4, my Nexus 5 had that too.... Concerning the Nexus 5, hardly anywhere it's mentioned that it is compatible with Qi wireless charging, , but I would not want a phone without it anymore.... (now with the S6 having it standard it will come to life i'm sure!!)
Any technician who would now the answer??
I'm thinking of buying a Samsung NOTE 2 compatible foil for a couple of dollars,put it in and and just give it a try...( I checked for the size, should be able to fit it in easily, hopefully it will not be too thick...
thanks in advance,
Wil
nice idea, but it won't work, i'm pretty sure. charging doesn't work with any two contacts you have on your phone especially if they're designed for something that runs on low power like nfc. it's the same as if you would try to take out the ir blaster diode and use it's two contacts to charge the phone... that's why there is a usb port on the bottom of the phone

I just bought an OEM Verizon Qi charging phone back, and two different Qi chargers. All sourced from Amazon, and listed as their best sellers.
Neither would connect to the phone and provide wireless charging. I am RMA-ing the new phone back to rule it out.
Could being on a custom ROM be interfering? I am on SkyDragon 4.0. I don't want to bother the dev on it, if it is a hardware problem.
Anyone else have a similar configuration that worked?

as far as i know, there is no "oem" charging backs available. you can buy an aftermarket sticker to make it work though.
anyways, the sticker should have 4 contact points, not 2. if you have that, the only way to properly verify its working is to put stock back on.
yes, it should work on SD, but to rma a device, without verifying the issue on the clean stock it was intended to run on is just not smart.
Yep, my back has four contacts, to match the internal contacts on teh phone.
it is branded LG and "Verizon 4G LTE", same as my original, hence why I referred to it as OEM.
I believe they made them standard for sale in Rest of World and optional for the US.
It is hard for me to believe that the charging on those two pins would be disabled in software, but considering the ridiculousness of US carriers, I put nothing past them. Which is why I wanted to know if anyone had one that worked.
I didn't RMA the phone, just the 4-pin optional Qi charging back plate. To call someone "not smart," when you clearly have no grasp of the facts...that's not smart.
I do know from experience that AOSP roms do break wireless charging, but SkyDragon is based off of stock, so it should work just fine.

i can only comment on what you post, and dont pretend to understand what you mean while vaguely explaining it.
what i perceive from your post appeared to be "not smart", and thats how i called it.
now that you have clarified, even returning the back plate before verifying the issue on clean stock, is not smart, but hey, its your time and money to do with as you wish.
good luck with that
Have you checked the other threads on this already?
There are only a few places to get the parts that enable wireless charging on the G3. As far as I know, the only official OEM part that verizon sells is the flip case. Any others are either the Sticker type, or an OEM part imported from europe, to get the correct 4 pin option, (Both at&t and korean variant parts will not work, as the 4 pins do not align correctly for the verizon phone.) and neither would have the verizon logo on it, unless it was an aftermarket mod from a third party, and I'd be a bit weary of those, personally. So I'm a little confused on the 4 pin, verizon logo part of your message. Still, if it is a correctly modified original part, with an aftermarket sticker attached on it, it should work on stock, and on most roms based of stock, like SD's ROM.
http://www.amazon.com/gp/product/B00N29ECGE
Bought one from Amazon last week from a US seller who unfortunately doesn't seem to be listed anymore (sold out?). Back was OEM with only the LG logo, and had the Qi+NFC pins in the correct place for the VS985 (the AT&T/Asian models had their pins aligned slightly differently).
Works with my Qi charger fine, and I too am running SD 4.0, as I value battery life.

Thanks for those constructive posts. Good to know that any issues I may be having are likely hardware. That points me in a good direction.
I should be receiving the replacement back today, so I can see if the problem is my phone core or the accessories.
Yeah, it's weird that the phone back would have Verizon branding, especially if it isn't their part. I can't see an advantage to doing that. The silkscreen looks identical to the OEM back that shipped with the phone.
EDIT: Ah ha! Now I understand what happened. This is the product: http://www.amazon.com/gp/product/B00NL9GWPY?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s01 I sort of blindly purchased, since it had a good rating. I now see that the seller has taken OEM backs and retrofitted them with a sticker! it's the same deal that you can do for six bucks, and not OEM. So, I am a stooge because I didn't read the fine print.
Amazon is not the place for popular items.

"Best sellers" on Amazon sometimes means "lots of victims".
A couple weeks ago I also search for a genuine LG/Verizon charging back, so that I wouldn't have to mess with a "stick-on" solution. While the items looked promising at first blush, a little research showed that there is no such device as a "genuine LG/Verizon charging back", despite what is obviously marked as such. The genuine charging back from Verizon is a clamshell-like cover, that apparently doesn't fit well with the usual belt clips. Life is like that.
Sadly, Amazon has become a haven for scammers offering counterfeit products of all types. A few months ago, I wanted to buy a power adapter for my Samsung tablet. The price on Samsung's site was $35; the price from all of the vendors on Amazon was $10, for devices clearly marked with the Samsung logo. However, reading the reviews showed that they were all cheap counterfeits that often failed in a month or two.
I have come to the point of only buying stuff on Amazon, that Amazon buys directly from the manufacturer. Ie, "sold by and ships from Amazon", not "sold by <whomever> and ships from Amazon".
As they say, "buyer beware".

Okay, now you do (grin).
Thanks, Dean. You're absolutely right.
I received the second replacement "wireless charging & NFC" cover, last night. Still doesn't work on my phone. But, it looks like a new Verizon cover, just one that had some yahoo replace the original NFC antenna with a cheap knockoff that purportedly would charge.
Ah, well, I got a new, unscratched G3 phone back plate and learned a lesson.
