I posted this in other place as well, so I'll just give a quick recap.

Used the Newisdom sticker. It worked great for a week or so. One morning after charging overnight, it no longer worked. I tried my leather back (also Newisdom sticker, previously had worked fine) and nothing. Tried replacing the sticker, and still nothing. Tried all 3 of my chargers, nothing. Looks like I'm not the only one with this issue....
[G4 Accessories] orgwizard:
Nope, and replaced my new wisdom with other brand on amz, same symptoms. Even tried finally different charger brand, behaved same as tylt. Only thing I've not tried is official circle case
[G4 Accessories] waylo:
What the two above posts describe is the real possibility of the wireless charging chip in the phone breaking down. I've experienced it 3 times! Each time, I've used the same back (oem quick circle case) on another new LG and it worked fine. If it's not the back, it's the phone.

This is simply poor engineering on LGs part.

There are multiple posts on multiple wireless charging threads describing this issue here on xda.
[G4 Accessories] orgwizard:
So I'm assuming then the only fix is phone replacement, and to hope it doesn't happen again? Has anyone reported similar issues with wireless charging stopping when used with the oem quick circle case? Wondering if it's a problem with these stickers breaking the phone or some inherent defect in the wireless capabilities in the phone
[G4 Accessories] waylo:
The first time this happened, I thought it was just a fluke, lemon of a phone to begin with. Then the second time, I knew it was more than just random chance. The 3rd?? Ridiculous.

The issue is that it won't break right away. Usually weeks to a month later.

Yes, phone replacement is the only way. And just watch to see if/when it breaks again.
[G4 Accessories] orgwizard:
But os it a bad sticker. Seems to be a lot of folks that have been working for a while even with the sticker.

Mine lasted less than a day
[G4 Accessories] waylo:
Could be a bad sticker yes. Only way to tell is to check it on a different phone, or check a new sticker on your phone.
[G4 Accessories] waylo:
For any who have tried wireless charging, I have a poll and questionnaire re: your experience. Would greatly appreciate your input.

[G4 Accessories] darioampuy:
cheap stickers are thick, and that thickness affect the connection because the contacts get loose, so you have to add thickness to the nfc and qi contacts to get a firm connection. some makers are selling improved versions that are thiner and/or have thicker contact points for a more secured connection. you should test the sticker coils with a tester before and after applying them to the cover to make sure you didn't got a defective one. just check for continuity in the nfc pins and the qi pins. damaged coils won't have continuity on the pins

---------- Post added at 10:08 PM ---------- Previous post was at 10:03 PM ----------

i saw that sticker has 4 pin qi connection while the other stickers have 2 pin... i wonder what are the 2 usually unused pins for...
[G4 Accessories] player911:
I think you're looking at the NFC side. But yea I noticed that. Mine only has 2.
[G4 Accessories] orgwizard:
How many are on the oem circle case?
[G4 Accessories] player911:
I don't know why NFC would require more than 2 (send and receive). Not sure what the other 2 are there for.

Here is what I found for a Samsung NFC chip.

1. Positive terminal (+)

2. Thermistor (or may be DATA)

3. Negative terminal (-)

4. Nfc antenna (antenna may be between negative terminal and this 4. pin)

I see 2 are for power. I think on our G4 phones, the actual NFC circuits are all built in, the only thing the 2 pins connect to are the antenna. So I do not know. There ARE 4 external pins on the back housing coming out of the phone, but the sticker I have, only 2 pins are actually connecting to anything.

Even on the built in NFC sticker (that you have to remove to install the NFC + Qi), it only had 2 pins. So I wouldn't be too worried about it.
[G4 Accessories] waylo:
As I recall, one user emailed the sticker company. They effectively said they put the extra 2 leads on there just to make their sticker stand out from the competition. Silly. But I guess it works.

OEM circle case has only 2 leads.
[G4 Accessories] binniebin:
Got mine sticker today but wireless charging is too slow to use it...

Wysłane z mojego LG-H815 przy użyciu Tapatalka
[G4 Accessories] the_scotsman:
Yep, wireless charging is always slower as it can't deliver as much current as a cable.
[G4 Accessories] woozzy101:
Its good if you do not need to charge fast. Examples would be on your work desk, in living room or nightstand when you go to bed. I have multiple wireless chargers all throughout the house and its awesome.

On a side note, Samsung has released Fast Charge QI Charging Pads for the S6 edge+ and Note 5. So hopefully while our LG G4 was built around the older slower wireless charging, the new wireless charging phones from LG and other manufactures will have the Fast wireless charging :)
[G4 Accessories] binniebin:
I tested sticker in work with Samsung wireless charger announced with s6. I know that slower charging is more effective. Gonna buy for home nillkin magic disk 2 it's cheap and looks good :)

Hello I am waiting for my g4 to come. So I would like to buy charging sticker and base from ebay or aliexpress. Can you recommend anything? Thanks in advanced
[G4 Accessories] player911:
Any sticker will do. Version 2 is supposedly the best stickers. Buy a good charging puck. One that has multiple coils for easier placement.

And look up my Wireless Charging Meltdown thread. Don't use a QC 2.0 fast charge charger cable to charge as it will break your Qi Wireless Charging.
[G4 Accessories] merta:
I ordered before you answer me. Thanks though. I have already read your thread. I do not have an QC fast charger so I am OK. What charging puck do you suggest ? From eBay if it is possible [emoji3]
[G4 Accessories] Pizza Thief:
Eyeing a Ballistics Jack Tough Maxx protective case. I'm wanting to know if this works thru it for wireless battery charging, cause if it does, then I wouldn't have to plug my phone in all the time to charge it! Can anyone confirm this?
[G4 Accessories] jerflash:
just picked one of these up. my H815 in red leather will be here in a few days...pretty excited!
[G4 Accessories] MicroMod777:
Were u order sticker from?
[G4 Accessories] jerflash:
Aliexpress got the one for 8.90 shipped as it looked slightly higher quality. See how it works. Will definitly be testing nfc and wireless charging before ripping the stock nfc sticker from me red leather back!
[G4 Accessories] the_scotsman:
Can anyone who has bought these let us know how it goes when you get them. I'm sure many people would love this to work!
[G4 Accessories] MicroMod777:
I ordered again from the original posted site as they seem their back in stock. We'll see which of my two orders gets here first!

The stickers available for the G3 that I got from Amazon.com weren't very good on wireless chargers. Either too small wireless pickup or too cheap. I tried like 3 different chargers. Hopefully the G4's will be better.
[G4 Accessories] MicroMod777:
Got a message from one of the AliExpress sellers on the 2 G4 stickers I ordered. What you think? Requested to cancel the order!

http://www.aliexpress.com/snapshot/6700044814.html?orderId=67518439524595
[G4 Accessories] jerflash:
Ya just got that too... I don't there there is much choice right now
[G4 Accessories] MicroMod777:
Maybe their having same issues as the G3 stickers. I wonder if the leather back covers hinder the signal.
[G4 Accessories] xgman:
There has to be another source. Aliexpress seems to have nothing but really bad reviews. What about some of those ebay sellers that had the sticker for the G3? Dam LG for making this so hard.
[G4 Accessories] OliviaOng:
Hi, can anyone recommend what wireless charger to go with the receiver ? Thanks
[G4 Accessories] MicroMod777:
The only one that I read always worked on the G3 stickers is this:

TYLT Vu Wireless Charger for all Qi Phones - by Tylt http://www.amazon.com/dp/B00DG8NUC8/ref=cm_sw_r_udp_awd_2VBBvb0RT9MBS

Aren't they the Ebay of China though like a Trillion is sales?
[G4 Accessories] xgman:
They have some of the worst reviews I have ever seen. In any case I ordered one through amazon seller and it was a bit more expensive at $12 and also from China, but I feel a bit better via Amazon and the seller reviews are better at least. Still not sure how to mount this once received. I think I have to pull off the existing sensor? can that be reused if needed later?
[G4 Accessories] GillRigged:

[G4 Accessories] *justintime*:
Aliexpress is the same shops/suppliers on Ebay so don't worry on that.

Ordered many times from AliExpress always with satisfaction.

Except sd cards ;)
[G4 Accessories] MicroMod777:
I bought that charger for my G3 and it would constantly loose conection. I blame it on cheap wireless stickers. On my Verizon G2 with built in charging it worked fine.
[G4 Accessories] GillRigged:
Hmm. I have never had charging issues from my G2, G3, Nexus 6 or Nexus 7. Must have been the sticker.
[G4 Accessories] MicroMod777:
On G3 you had to first mark the spot where sensor fits with pen. Then tear off NFC sticker, and put on new one.
[G4 Accessories] PsyMonkey:
I ordered from here a few days ago

http://www.aliexpress.com/item/Wire...-Housing-Back-Cover-Case-T01/32357030303.html

And just receive a notification that it has shipped.
[G4 Accessories] *justintime*:
Mine also did the seller contact you if it is compatible? Because the weren't sure.

We don't know when or if this item will be back in stock.

I wonder how much and if it was actually ever available.

I would love to see NO NFC versions so I do not have to butcher my leather cover to get the NFC out.
[G4 Accessories] Johnston212:
I don't understand how the qi chips are not compatible with the AT&T models. Doesn’t the sticker/chip simply enable qi charging?
[G4 Accessories] denco1:
Hardware does as well, the input from the coil has to be regulated, the coil doesn't contain a chip that's in the phone.

At&t phones use the other standard they support, PMA.
[G4 Accessories] Johnston212:
Thanks for clearing that up. At least it saves me from wasting $60 on the bundle deal. As if the cases weren't bad enough.
[G4 Accessories] wargreymon89:
Found this on eBay and ordered: http://www.ebay.com/itm/Wireless-Ch...282?pt=LH_DefaultDomain_0&hash=item419767a102

[G4 Accessories] Johnston212:
Same here. Now let's just hope that I can get mine
[G4 Accessories] yumyumgor:
Just got it today. Removed the original NFC from my leather cover and followed the youtube instruction.

Worked flawlessly. I can wireless charge and use NFC now!
[G4 Accessories] Lock-N-Load:
And photos of yours installed on the leather? Any issues with removing from the leather?
[G4 Accessories] player911:
Can you post a link to the location you purchased it from so we can get a confirmation on what works.

I really hate the idea of butchering up a new case just to make it function the way it should out of the box but it gives me relief that the fix is easy and confirmed working.

I would suggest giving it a few days to test. Notably the GPS. I know the Verizon G2 (the only model with Wireless Charging) had the Qi Coils mess up the digital compass. Specifically it would get confused at intersections and think you were going the wrong way. It would frequently try and reroute every time I got to a red light because it thinks I turned.

Obviously you would want to test the NFC also, since you are replacing that antenna with a new one.
[G4 Accessories] yumyumgor:
Upload a pic as attached. I removed the original leather color NFC sticker. Its quite easy as the cover is quite tough.

Then just follow the youtube link in page 5 in this thread.

I brought it from the aliexpress shop mentioned in page 2/3, same shop producing the youtube video I think.

I got all the info from this thread, so I guess its time for me to share my story
[G4 Accessories] jerflash:
Waiting for my sticker to come... Should be here in a few days
[G4 Accessories] Zoidy:
I received the Quick Circle case from Amazon.co.uk today. Cost £22.

I was going to transplant the sticker into my leather back. Not so sure now!

I would use the QC case but it's really no substitute for the slimness of the leather back!

OK so I bit the bullet and tried the transplant but it didn't work. Pretty sure I had everything lined up correctly. Managed to stick it back into the QC case though and it works fine back in there!
[G4 Accessories] woozzy101:
Which LG G4 version do you have ?

thanks :)
[G4 Accessories] MicroMod777:
What country you live? How you get it so fast?
[G4 Accessories] yumyumgor:
LG H-815T whichis the single SIM model. I was told the dual SIM version doesn't support wireless charging.

I stay in Hong Kong that's why I got the shipment in 2 days.
[G4 Accessories] MicroMod777:
Lucky you! I hope the delivery boat doesn't take a month to get to USA!:)
[G4 Accessories] MicroMod777:
Well anybody else get their stickers? Pluging in my G4 at night sure blows.
[G4 Accessories] frigidazzi:
I am in the US and ordered from aliexpress as soon as the link was posted on XDA. I haven't got mine yet. I feel you. i hate plugging this in!
[G4 Accessories] Lock-N-Load:
They are popping up all over eBay. I got alerts today from eBay and see them now for about $5.
[G4 Accessories] player911:
I just bought one off Amazon along with a case. Think it was $8. Case was $9

Edit

Ah crap it must've not been added to my order. Where's the best place to get one fast?

I just bought this one with a wireless charger for $12. Says estimated date is June 19th
[G4 Accessories] Lock-N-Load:
EBay has several options.
[G4 Accessories] player911:
I am pretty sure the NFC and Wi-Fi share the same antenna. I could be wrong.
[G4 Accessories] discokrueger:
You're probably wrong. I still have Wifi-connectivity when removing the back cover.
[G4 Accessories] woozzy101:
I know people that have used their phone without a back cover to fit their case and have not lost WiFi. So no WiFi antenna on back cover :D
[G4 Accessories] player911:
Good to know.

Anyone who has gotten their stickers and using them, have you noticed any changes in GPS usage? On the G2 Verizon with built in Qi... GPS was wonky. Supposedly the coils of the Qi messed with the digital compass
[G4 Accessories] xgman:
Good news that it worked. Still waiting for mine from Amazon overseas which is now in Illinois.
[G4 Accessories] Palmermj0:
I picked one up from aliexpress here

http://www.aliexpress.com/snapshot/6698406642.html?orderId=67522447614730

Fitted it today to a black leather back with a slim case and works fine. Gets a little warm when charging but my g3 did too
[G4 Accessories] MicroMod777:
Glad to hear it works. Ordered same one. Where u live that u got it so fast?
[G4 Accessories] Palmermj0:

[G4 Accessories] audiowikid:
So i picked up my ATT h810 g4 and from what i can see it appears to have both pins for Qi and PMA not 100% but i asked my buddy who knows about this and he said they were Qi pins. Now i was looking at this site http://www.aliexpress.com/item/Wire...-Housing-Back-Cover-Case-T01/32357030303.html where everyone is ordering theirs from and the picture shows the sticker for Qi but it lists my model in the description. Does anyone know if this site does in fact have the sticker for the att h810? i ask because i have PMA mats that i was using with my G3 and dont want to change the mats to Qi. You can see the PMA pins to the right of the battery next to the NFC pins so there are 4 together and the Qi pins are located at the top of the battery, for those wondering :D

Also for those who are curious about replacing the sticker it is actually easy, i used a blow drier with my g3 to heat the case and then you can peal the sticker off.
[G4 Accessories] MicroMod777:
Heat? lol I just yanked it off on my G3.
[G4 Accessories] Lock-N-Load:
yeah.. totally wrong. GPS is on the motherboard. No antenna on the backside of a case :) I don't know of a phone that even has that setup. This would mean that the inside back case would have to make contact with the phone on some pins - much like QI does - and I have never heard of such a setup when it comes to GPS.

I read 1 guy here 1 time report 2nd or 3rd or 4th hand that they heard about GPS being negatively affected by QI and I never have seen it again (until here). I would love to read an actual thread where that is discussed as even possible and confirmed as having happened. Not saying not possible, but in all of my geeky XDA travels, I have not seen this talked about.
[G4 Accessories] xgman:
I installed mine perfectly and it does not work at least with the Nokia or Samsung chargers that worked 100% fine with my G3. Not sure what the problem is. Guess I'm out of luck and the money. (Verizon/Blk Leather back)

By the way the process destroys the old one peeling it off.
[G4 Accessories] ThePhoneGeek:
DELETE
[G4 Accessories] xgman:
I ripped the sticker out and just lightly put it back on and now it is sort of working. The pin location, height etc is very finicky. I also notice a bit more heat from the phone when I put the sticker on. Maybe heating up the thicker magnet on the charging sticker? Now if someone would just release a quick charge rated wireless charging pod.....
[G4 Accessories] MicroMod777:
Well my dang sticker arrived today, but I wasn't home to sign for it! Was left a note by USPS. Then I drove to the USPS office and the postal worker hadn't come in yet. So now I have to go to the USPS office after 8:30am tomorrow to pick it up. What a drag!
[G4 Accessories] frigidazzi:
I have to sign for that 8 dollar thing when it comes? ug that's annoying!!
[G4 Accessories] player911:
It was a common problem on the Verizon G2. It messed with the digital compass (my theory anyway) thus every time you were at an intersection, it would think you turned and would reroute, only to have to reroute again. Screwed me up may times on the highway and downtown where it would reroute the minute I needed to know which direction to take. It was definitly a problem. I dont think Qi messes with GPS directly. We think it was placement of the compass sensor in relation to the Qi. Makes sense. Metal that is electrically charged becomes magnetized and can mess with your north bearing.

Anyway they are good questions to have answered before everyone starts ripping their existing antennas out for new.

Sucks they are iffy. I have 2 nokia chargers I use and a samsung for a spare in my travel bag. I really hope official backplates are available soon. Really stupid to not have that available at launch.
[G4 Accessories] MicroMod777:
Well isn't $8 for us like $100 to them? I agree that it is really silly to have to sign for it. It does protect them from losses.

So $2.00 for sticker, $4.00 for shipping and $2.00 for signature.
[G4 Accessories] tersagun:
I was just about to order few from those 8.80$ kits for my friends but if it doesn't work with most of the chargers...

Damn, that's a sad news.
[G4 Accessories] MicroMod777:
I'll find out tomorrow sure enough!
[G4 Accessories] *justintime*:
Received yesterday and fitted it in the leather case. And everything working okay.

I received an extra sticker to stick over the nfc and coil. It has silver foil on it. Looks like an interfering shield.
[G4 Accessories] yumyumgor:
It worked on my 2 Nokia wireless charging pads, LG wireless Qi charger and 2 other brand Qi chargers.

I found that if the phone is getting too warm, the wireless charging actually stops. I experience that consistently in my car when I'm using the Nokia wireless charging phone holder on my windshield. Direct sunlight heats up the phone and it stops charging.

I didn't put on the foil sticker that comes together. I tried to put it on and wireless charging stopped working. Removed it and wireless charging works again.
[G4 Accessories] Marcismo55:
Can you confirm which sticker you used? Seems like there are a few different links posted throughout the thread pointing to different products.
[G4 Accessories] *justintime*:
This is the cover sticker. Underneath is the coilsticker.
[G4 Accessories] xgman:
What is the purpose of the cover? And which seller was this one? It looks way better made than the one I got.

So far I'm finding that unlike the G3, the sticker isn't worth the slow charge if you have a "Quick" Charger and it seems unreliable.
[G4 Accessories] *justintime*:
I bought mine here.

http://www.aliexpress.com/item/Wire...-Housing-Back-Cover-Case-T01/32357030303.html
[G4 Accessories] xgman:
Thanks. Your pic looks better than theirs. I ordered another one from them today. I've pulled the other one out and in to many times.
[G4 Accessories] centran:
So it seems like no matter what you need to remove the NFC sticker from your current back? You can't just slap one of these stickers over the current one?

I'm betting doing so will be a problem with leased phones.
[G4 Accessories] xgman:
My sticker just stopped working and is more or less useless. It pisses me off that LG didn't include this $5 feature to begin with. Now I can't replace the original one back so I have to keep ordering these till one works. I am regretting buying this phone now......
[G4 Accessories] Shane_pcs:
Check the dents on the contacts for your current sticker. Usually you can determine how good a contact is being made and adjust accordingly. I have seen some people that were able to find out which contact wasnt making a good connection and fixing it.
[G4 Accessories] MicroMod777:
I spend an hour trying to get my sticker to work. Up, down, sideways, make the contacts a little higher, etc, and nothing worked. I even started sweating out of frustration. These things are junk. At this point I'd rather spend $50 bucks for a plastic back with wireless charging included from LG if it works.

At least I only lost $8 bucks. Gonna send the seller a message.

EDIT.... GOT IT FIXED!!! SEE FOLLOWING POSTS.
[G4 Accessories] *justintime*:
Pfewww that looks ugly. Where did you buy?
[G4 Accessories] MicroMod777:
I got the defective ones from here! I originally had placed 2 orders with another seller but he sent me a message that they were having problems with the sticks. Looks like this other seller, "MobileMate Arena" maybe didn't care and still sold them.

---------- Post added at 12:18 PM ---------- Previous post was at 12:14 PM ----------

Theses did not work for me. I sent the seller a message that they are defective and I want a refund.
