Samsung Galaxy S8 Active NFC Antenna and Charging Coil Assembly Replacement - Samsung Galaxy S8 Active

Step 1 | SIM Tray/Card

Insert the SIM card ejector tool (or an unfolded paperclip) into the small hole on the left side of the top edge.

Press gently to eject the SIM tray.
Remove the ejected SIM tray from the device.

Incorrect reinsertion may damage the SIM card or tray.

Orient the SIM card with gold contacts up and notch bottom right. Reinsert by pressing gently into the slot.

Step 2 | NFC Antenna and Charging Coil Assembly

Removing the back cover will compromise waterproof seals.

Have replacement adhesive ready or avoid liquid exposure during reassembly.
Remove four 3mm black screws from outside edges using a TR6 Torx Security Screwdriver.
Take off rubber bumpers from top and bottom device edges.

Step 3

Avoid overheating, as this may damage the OLED display, battery, or other internal components.

Apply gentle heat from a heat gun, iFixit iOpener, hair dryer, or hot plate to soften adhesive along back edges for approximately one minute.
Handle the metal frame carefully as it may become hot during this process.

Step 4

Insert a Jimmy tool under the edge of the back cover.

A suction handle is ineffective on this textured surface; do not rely on it for grip.

Insert an opening pick into the seam to prevent the seam from closing if the Jimmy tool slips or is removed accidentally.

Cut slowly around the top section, avoiding cables for fingerprint sensor and camera. Do not pry too far into the device's top to protect the fingerprint sensor.

Slide the Jimmy tool down the sides of the device, separating the adhesive.

Step 5

Use a pick to slice through any remaining adhesive.

If using replacement adhesive strips, carefully remove excess adhesive with a Jimmy tool.

Open the back cover just enough to access the fingerprint sensor flex cable connector.
The fingerprint sensor cable is located near the front-facing camera; gently pull the back cover off to avoid damaging it.

Step 6

Flip the cover slowly and set it aside.
Use the flat end of a spudger to disconnect the fingerprint flex cable.
Remove the back cover.

To reconnect, ensure the back cover is angled over its socket and use the flat end of a spudger to snap the flex cable into place.

Step 7

Use a Phillips #00 Screwdriver to remove the following screws:

Eleven 3.5 mm screws.
Two 2mm screws.

Step 8

Remove the NFC antenna and charging coil assembly with a flat-end spudger.
