Samsung Galaxy S9 Plus NFC Antenna and Charging Coil Replacement

Careful: overheating can damage the AMOLED display or internal battery.

• Switch off your phone.
• Apply an iOpener to loosen the rear glass adhesive for at least two minutes, repeating as needed.
• If the iOpener is insufficient, use a hair dryer, heat gun, or hot plate with caution.

Be cautious when cutting through the adhesive — risk of damaging the fingerprint sensor flex cable.

• Identify the adhesive patterns as seen in the provided image.
• Focus on slicing through the thick and thin areas of adhesive indicated.
• Avoid cutting or prying near the fingerprint sensor flex cable to prevent damage.

Cracked rear glass may prevent suction cup adhesion.

• Apply strong tape or superglue to assist suction cup adhesion.

Press a suction cup onto the back cover.

• Lift the bottom edge with your suction cup, creating a slight gap between the back cover and frame.
• If necessary, apply more heat to soften adhesive and try again.
• The adhesive cools quickly; repeated heating may be required.

Insert an opening pick in the gap and slide it to the bottom right corner.

Insert a second opening pick into the gap.

• Slide it towards the bottom left corner.
• At the bottom, insert a third opening pick.

This opening pick stays in place to prevent resealing of adhesive during rear glass removal.

Insert the tip of the opening pick at the bottom left corner of the S9 Plus.

• Slowly slide the opening pick along the side until you reach the middle, cutting adhesive as you go.
• Leave the opening pick in place.
• Repeat on the bottom right corner, sliding the opening pick up the frame and leaving it in position.

Insert a fourth opening pick at the right side of the frame and slide it to the top right corner.

• Slide a fifth opening pick along the left side of the phone to the top left corner.
• Use the opening pick to cut the remaining adhesive under the upper part of the rear glass.

Do not open the phone all the way yet, as the flex cable for the fingerprint reader is still connected to the motherboard.

Locate the volume button on the rear glass.

• Lift the side of the rear glass near the volume button using a plastic spudger.
• Pry up and disconnect the fingerprint sensor flex cable with the edge of a spudger.

• Remove the rear glass.
• When reassembling, use the provided instructions to:
• Rear Glass Reinstallation Guide
• Replace adhesive and reinstall rear glass

Note: This process requires careful handling of fragile components.

Transfer the rear camera bezel with fingerprint, if applicable:

• Rear Camera Bezel and Fingerprint Transfer Guide

Remove nine 4 mm Phillips #00 screws.

Insert a precision pick under the right side of the NFC cover.

• Flip the pick sideways to lift the cover out of its plastic clips.
• Pry up along the edges to release all remaining clips.

Remove the plastic cover to access the NFC antenna and charging coil.
