Introduction

Use this guide to replace a broken NFC antenna and charging coil assembly in the Samsung Galaxy Note8.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

If your battery is swollen, do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

Opening the Samsung Galaxy Note8 will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally, but will loose water-protection.

This guide involves removing the rear glass cover, you will need replacement adhesive to reattach the back cover to the phone.

Step 1

Switch off your phone.
Prepare an iOpener for softening the adhesive on the back of the Note8.
Apply the iOpener on the back of the Note8 along the side with the power button.

I used a heat gun to soften the glue - worked it around the edges, moving the heat gun quickly. As this is my first attempt, I’m still calibrating on this - but other guides mention getting the back cover hot enough so as it’s just too hot to touch. I also have a temp probe on my multi-meter, and I measured appx. 75 deg. C.

One of the other guides showed using a electronics hot plate set to 105 deg C for 60 sec.

Step 2

Use a suction handle to lift the back cover and create an opening pick to get in the gap.
Since the back cover is also slightly curved at the edges you want to insert the opening pick at a lower angle from underneath.
Start at the middle of the side and cut the adhesive while pulling up with the suction handle.
Be careful not to lever the opening pick too much to avoid breaking the back cover. Rather pull with the suction handle and use the pick for cutting the adhesive.
Move the pick towards the bottom corner and leave it there to keep the adhesive from resealing to the case.
Use another pick and move it to the top corner.
If it's getting harder to move the pick you might need to reheat the iOpener and apply it to the back cover again.

I used an X-acto knife with the flat blade to get it started. I tried using the suction cup - but it’s difficult to get good leverage. Once I got the cover started - I used the metal pry tool (sharpened with a dremel file) and a business card to work it open.

This is definitely the hardest part.

Once off I see all the glue on the curved part of the chassis NOTON THE BACK. Apply heat to curved edges.

Step 3

Again take another opening pick and carefully move it around the corner and along the top edge.
Reheat with an iOpener if necessary.
Leave the pick at the top right corner to keep the adhesive from resealing.

Step 4

Rotate the device and start to separate the adhesive at the bottom with another opening pick.
Leave the pick at the bottom right corner to keep the adhesive from resealing.

Step 5

When the adhesive has been separated on all three sides properly you will be able to slowly lift the back cover.
Don't force it open. Use an iOpener to again soften the adhesive if the back cover won't come off or starts to bend.
Pay attention to the fingerprint sensor connector when flipping the back cover open. You might need to disconnect it as described in the next step.

I broke the back camera cover for the NUT 8 and then I bought a commercial cover and installed it but the quality of the picture became very bad and my question is, do you know where to get the original cover at a reasonable price?

Step 6

Use a pair of tweezers to disconnect the fingerprint sensor.
The connector might already have come off when flipping the back cover open.

don't skip disconnecting the sensor, even if isn't still glued to the case. it has to move away from the NFC/charging coil assembly in order to free the latter so it can be lifted away from the battery.

Step 7

Remove the back cover.
To prepare for the reassembly remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

How do you swap the fingerprint sensor

You can use a tweezer to swap the fingerprint sensor, you might be careful when doing the step 6, additionally, a tweezer will be helpful when reassemble the fingerprint sensor. please note that your new back cover needs to have the fingerprint adhesive on. most of the product did not have. i have get a LUVSS brand from amazon which came with all OEM adhesive and full set tools, even a B6000 glue, best option to go for replacing the note 8 back glass

Step 8

Remove the ten Phillips #00 screws.

Step 9

Use an opening pick at the top edge to get between the NFC antenna and charging coil assembly and the case.
Lever the top of the assembly out of the case.
