G4 SlimPWRpatch - Ultra Thin Qi Wireless Receiver NFC Antenna Sticker Card Patch Module for LG G4. Compatible with Verizon, T-Mobile, Sprint. Recommended to use with QiStone+, WoodPuck or KoolPad

This is my first experience with wireless charging and I'm happy to report the SlimPWRpatch from Fonesalesman works like a charm. Besides the clear and easy to understand instructions that comes with the patch, there's also a great step by step video available to watch online before you do the installation. My own installation went perfectly on the first attempt thanks to the quality design of the patch. I've had absolutely no issues at all with aligning my phone on the wireless charging pad- just set it on and it charges every time. I especially liked the pre-allignment adhesive tabs that allow you to test and re-position the patch BEFORE permanently adhering the patch to your phone! One tip I'd like to pass along: The factory installed NFC sticker on my phone came off very hard! I assume because the phone is over a year old and has gone through many charging (warm up / cool down) cycles which apparently makes the sticker dry and brittle. Mine came off in tiny fragments of plastic and dried adhesive, and I resorted to using hot water and Goo-b-Gone to completely remove it! My LG G-4 back cover happens to be the plain plastic type so this method doesn't cause any harm as long as you dry it completely, and keep the phone body well away from your work area (No kidding!- it was a huge mess!) If you have the leather back cover, you'll need to take extra care in the removal process if your factory sticker is as stubborn as mine was! In either event the SlimPWRpatch is well worth the money and brief installation time, and I'm happy to recommend it.

I have purchased a few different versions of this brand (SlimPWRpatch) over the years for many different phones. I've never had a problem until now. It worked fine for a couple of months in a brand new back (I used the one from the LG promo so I wouldn't void the warranty on the original case). However, NFC then stopped functioning, which is really bad considering I use a Yubikey as part of a multifactor authentication for a password manager. At first I thought it might be the phone, but I swapped back in the original cover and NFC worked fine with that, so it was definitely this patch. Qi charging still worked without issue, so it was pretty odd. I ended up buying a different Qi receiver patch (NeWisdom one) that came with a protective sticker that matches more of the OEM back and it has been working fine with NFC and Qi charging for now.

I bought this slim patch to use on my LG G4 phone back. I was using it in conjunction with the CHOE T513 wireless charger.Regardless of how I attached the slim patch I could not get the phone to charge with the back cover on the phone.The shape of the phone is slightly curved but I ensured the contacts were connected to the phone pins. If I taped the patch to the phone and tried to charge the phone without the back cover it would charge flawlessly.In the end I couldn't determine if it was a problem with the charger or with the patch, so I bought "Circle Case" with built in wireless charging. This worked flawlessly with my CHOE T513 charger.I gave this slim patch a 3/5 because I know that it worked with the cover off, but can't put all the blame on the patch. Maybe my charger was not strong enough to charge through the curved, thick leather case. Buyer beware, your mileage my vary with this product.

It was fairly straight forward and easy to install. Worked right away with NFC and Qi charging without any difficulty. I recommend watching the video for installation, and testing it before final application. It is thicker than the sticker that comes on the back cover originally but the back does still snap in place.

After buying the LG G4 circle case, I wanted to try this patch just because you can no longer use certain protective covers with the circle case. So, I watched the videos about this product and saw how easy it looked to install it. Then, I bought it to try it out. I watched the video one more time and then went about removing the OEM NFC backing. I installed this just as prescribed in the video, and it worked the first time out. I now have it permanently installed on my LG G4. I'm using it with the Soundbot wireless charger and it charges fine. If you have a LG G4 and you want wirless charging, then this is a great option. I highly recommend this.Note: I haven't tried the NFC yet. I will update this accordingly if the NFC doesn't work. Otherwise, you can assume that it does work.June 10, 2018 update- the NFC works great. Great option.

I have an extra original cover as reference, so I can say that with 100% confidence. The installation video is also a bit misleading since I had to literally scrub off the copper NFC antenna with sandpaper since it was glued with cyanoacrylate or something equally strong.Think twice (or even thrice) before ordering this thing. It is not as easy to apply as they want you to believe and NFC functionality doesn't seem to work at all.UPDATE: As of today (March 16, 2018) it stopped working. No wireless charging, no NFC, nothing. It is dead. Very disappointing. Changing three stars to one.

I was skeptical at first, but it works quite well. It was not as easy to install as the video lets on, seeing how the NFC sticker on my phone's cover refused to peel off in one continuous piece, but the included "guitar" pick was a lifesaver. It was extremely useful in cleaning up the residue. The sticker itself is not as robust as I would like, but we'll see how long it holds up.TIP: Use the included pick instead of a pocketknife or screwdriver to remove the sticker and sticker residue so you don't scratch the cover. Deep gouges could interfere with the new sticker's adhesion.
