Here are step-by-step instructions for installing a QI Wireless charging + NFC antenna sticker on your LG G3, replacing your existing NFC-only antenna. As a bonus, I was able to get the existing NFC antenna off in one piece without damaging it (I think), so in theory I could put it back on if I needed to go back. I don’t know why I would do that, but it’s good to have options.
These instructions should generally work for other similar phones and compatible Qi stickers.
I purchased the LG G3 Qi Wireless Charging + NFC Antenna Sticker for Verizon VS985, T-mobile D851, Sprint LS990 (really it works for any version of the G3) and a PowerBot Qi Enabled Wireless Charger Inductive Charging Pad Station from Amazon. The total came to under $21.
Note that there are two stickers here. The one on the right goes on first. The top two connectors are for the NFC antenna. The bottom two are for charging.
I used a hairdryer, a pencil, and a small screwdriver.
Step 1 – Turn off your phone and remove the back.
Note the location of the sticker. Again, you are replacing the first two connectors (far right in this orientation), and you will be adding two more to the left of them for charging. It’s important that these line up correctly when you install the new sticker.
Step 2 – Mark the location of the connectors
Using a pencil, mark the location of the metal connectors on the exiting sticker, both vertical and horizontal so you can line up the new sticker correctly when you install it.
Step 3 – Remove the existing sticker
Set the hairdryer to high heat but low fan. Use the hairdryer to warm the area of the sticker where the connectors are located. This will loosen up the glue on the back of the sticker and allow you to pry it away from the back of the case with the small screwdriver.
Use the hairdryer to heat sections of the sticker as you pull it away from the case. Remove the side where the connectors are, then begin to work up the other side until you finally remove the small strip on the opposite side of the hole in the case. Basically you are working in a “U” shape starting with the connector side, and working to the bottom and then up the other side.
When you are done, the existing antenna should have come off cleanly.
Step 4 – Install the new sticker
Starting with the small strip with the connectors, use your pencil markings to carefully line them up. Once you have that right, work your way down and stick the large part of the sticker to the case.
Double-check to make sure the top two connectors look like they are in the right place per your pencil markings. You want to make sure this is right before you go to the next step.
Step 5 – Install the covering sticker
I have to admit, this part was a pain. I rotated the case around a lot trying to make sure I understood exactly how this sticker should fit over the first one.
Again, I started with the strip that covers the portion with the connectors, then worked my way across, down, then back up the other side. I had a couple of false starts, but was able to pull back the sticker and start again until I finally got it.
Step 6 – Test!
Put your phone back together and turn it on. Connect the Qi pad to a micro-USB port. Place the phone on the Qi pad and see if it works. You need to get the pad centered on the location of the sticker. It’s slightly below the mid-point on the phone.
Once everything appears to work, go ahead and erase your pencil markings.
I hope you found these instructions helpful. Good luck!
