Samsung Galaxy S8 NFC Antenna and Charging Coil Assembly Replacement
Duration: 45 minutes
Steps: 14 Steps
Before getting down to the nitty-gritty of disassembling your phone, make sure to drain that battery to under 25%. It's all about safety—batteries can be a little temperamental and may catch fire or even explode if punctured, but draining it first really reduces the risks. Keep it safe, keep it cool!
Ready to give your Samsung Galaxy S8 a little TLC? This guide will walk you through swapping out the NFC antenna and charging coil like a pro! We'll start by removing that rear glass cover, and don't forget to get some replacement adhesive to secure it back once we're done. Before diving in, make sure your battery is below 25%—it helps avoid any firework moments if we accidentally poke it. So, let's keep everything safe and sound while we get your phone back in action!
Step 1
If you're working with carousel microwaves, double-check that the plate can spin without any hiccups. Watch out—if your iOpener gets stuck, it might overheat and cause a burn, so keep it moving!
It's a good idea to give your microwave a quick clean before diving into this repair. Any leftover gunk on the bottom might just end up stuck to your iOpener – and nobody wants that!
- Pop that iOpener right in the middle of the microwave like a boss!

Step 2
Keep an eye on the temperature of your iOpener during the repair—overheating can lead to a burst, and no one wants that! Aim to keep it under 100˚C (212˚F).
If your iOpener looks a little puffy, just don't touch it. Safety first!
If it's still too hot to handle in the middle, don't sweat it—let it cool down a bit before you heat it up again. A properly heated iOpener should stay toasty for about 10 minutes.
Microwave power varies, so adjust the heating time accordingly. Your iOpener is ready to rock when it’s just a tad too hot to handle!
- Give the iOpener a quick thirty-second warm-up in the microwave. It's like a spa day for your repair buddy!
- As you go through the repair, keep an eye on the iOpener – when it starts to cool down, just pop it back in for another thirty seconds. Simple as that!

Step 3
Be cautious, the iOpener gets super toasty! Handle it with care and consider using an oven mitt for extra protection.
- Carefully take the iOpener out of the microwave by grabbing one of the two flat ends—avoid the hot center like it’s a hot potato!

Step 4
Caution! The iOpener gets super toasty, so make sure to only grab it by those handy end tabs.
No microwave? No problem! Just pop your iOpener into a pot of boiling water to warm it up.
- Grab a pot or pan and fill it with enough water to cover your iOpener.
- Bring the water to a boil, then turn off the heat.
- Drop your iOpener into the hot water for 2-3 minutes—make sure it's taking a full bath!
- Use some tongs to carefully lift the iOpener out of the water.
- Give it a good towel dry so it doesn’t drip everywhere.
- Your iOpener is all warmed up and ready to go! If you need to reheat it, just boil the water again, turn off the heat, and let it soak for another 2-3 minutes.

Step 5
You can use a hair dryer, heat gun, or hot plate to help with this, but keep an eye on the temperature! We want to avoid turning your phone into a mini sauna, as the OLED display and internal battery don't handle heat like a champ.
Opening up your phone? Keep in mind, it might mess with the waterproof seals. Have some fresh adhesive on hand just in case, or be extra careful with liquids if you choose not to replace it while reassembling.
While the adhesive is taking its sweet time to soften, go ahead and read the next step so you know where to start prying.
You might need to give the iOpener a few rounds of reheating and reapplying to get your phone toasty enough. Just follow the iOpener's instructions closely to avoid overdoing it.
- Warm up an iOpener and stick it on one of the long edges of the S8 for about 2 minutes to loosen things up.

Step 6
- In this part, you'll carefully slice through the adhesive sealing the rear glass panel. Think of it as a gentle dance around the edges. The adhesive layout is shown in the first image—so keep that visual in mind. The prying pattern from the outside looks like this: areas with thick adhesive, and spots with thinner adhesive. Just a quick tip—avoid prying near the fingerprint sensor to keep it safe. If you need a hand with any tricky parts, you can always schedule a repair to get professional help.
Step 7
The suction cup might struggle to get a good grip on the curved glass surface.
If the phone’s back cover is cracked, the suction cup could have trouble sticking. Try using strong tape to lift it, or carefully superglue the suction cup in place and let it set before continuing.
Because of the curved glass, you’ll be pushing up instead of sliding the tool parallel to the phone’s surface.
- Once the back panel gets warm, go ahead and apply a suction cup as close as you can to the heated edge - just be careful not to get too close to the curved edge.
- Next, pull up on the suction cup and slide an opening pick under the rear glass - taking care not to push too hard, since you don't want to risk damaging anything.
Step 8
- After securing the tool snugly under the glass, heat things up again and slap the iOpener back on to loosen that sticky adhesive action.

Step 9
Take your time and be gentle so the tool stays snug in the seam. If you hit a snag while cutting, just give the iOpener another warm-up and try again.
- Gently slide the opening pick down the side of your phone to loosen that stubborn adhesive and get things moving.

Step 10
- Go ahead and repeat the heating and slicing dance on the other three sides of your phone.
- Keep an opening pick wedged in each side as you move along to stop the adhesive from sneaking back together.
Step 11
As you lift the glass, take a peek and make sure that orange cable with the blue connector has popped loose.
If the fingerprint sensor cable is clinging on or stays super tight, pause right there. Use the pointy end of your spudger to disconnect it before opening the phone any further.
The fingerprint sensor cable makes a cozy connection between the phone and the rear glass, hanging out near the main camera. It's a bit of a shorty, so it'll easily disconnect as you gently lift off the rear glass. Keep that in mind as you work your magic!
- Grab those opening picks and slice through any stubborn adhesive holding things together. Once you get a little space, you're almost there!
- When putting everything back together, make sure to line up that fingerprint sensor cable. Once it's in position, gently press down with your spudger to snap the connector into place. It's like a gentle high five for your phone!
- Carefully remove the glass from the phone. Take your time with this step—no need to rush!
Step 12
If you're feeling adventurous, you can pop that back cover on without swapping out the adhesive! Just make sure to clear away any big adhesive blobs that might stop it from sitting down nicely. Once you're ready, give that back cover a little heat and apply some pressure to lock it in place. It might not be waterproof anymore, but trust me, that adhesive is still strong enough to keep things together!
Before sealing everything up with new adhesive, don’t forget to power on your phone and give your repair a quick test. This way, you can be sure everything's working smoothly!
- Ready to give your phone a fresh look? Let's get that new back cover on!
- Start by checking out this guide to either pop that old back cover back in place or to attach a new back cover that doesn’t come with adhesive already. Easy peasy!
- If you're swapping in a new part, don't forget to move over the camera bezel. Need a hand with that? Just follow our camera bezel replacement guide.
- Grab your trusty tweezers and gently peel off any leftover adhesive from the phone's chassis. Next, it’s time to clean up! Use some high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prepare those areas for the new adhesive.
- Now, peel the adhesive backing off the new rear glass. Line up one edge with the phone chassis—take your time—and then press down firmly to secure it in place. You’ve got this!
Step 13
- Start by grabbing your Phillips #000 screwdriver. Then, carefully remove the eleven 3.7 mm screws holding things together. Keep them safe—you'll want to put them back in when you're done. If you need a hand at any point, you can always schedule a repair.
Step 14
- Now that you've reapplied the adhesive, it's time to put your device back together—just retrace your steps like a pro!
- Once you've wrapped up the repair, give your work a quick test run to ensure everything's working like a charm. And remember, if you hit a snag, you can always schedule a repair.
