Switch off your phone before starting.

The Samsung Galaxy S9 has very strong adhesive. Be careful not to overheat the phone, as this can damage the AMOLED display or internal battery.

Alternative heat sources include a hair dryer, heat gun, or hot plate.

Locate the thick and thin areas of adhesive on the back cover as shown in the image.

• Slice through the adhesive in these areas using a suitable tool (e.g. spudger or craft knife).

Avoid cutting in this area to protect the fingerprint sensor flex cable.

If rear glass is cracked, suction cup may not stick.

• Apply strong tape or superglue to suction cup for better grip.

Lift back cover's bottom edge with suction cup, creating a small gap between the cover and frame.

This may require significant force; apply more heat if necessary.

• Insert opening pick in created gap and slide to bottom right corner.
• Insert second opening pick at bottom left corner.
• Insert third opening pick to prevent adhesive resealing.

• Insert only the tip of the opening pick at the bottom left corner.
• Slide it along the side to the top, keeping it away from other components.
• Leave the pick around the top corner; this will prevent adhesive resealing.

Apply heat as needed while sliding an opening pick from the bottom right along the side to the top.

• Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.
• Do not open the phone completely yet, as the fragile fingerprint sensor cable still connects it to the motherboard.

The back cover is under tension; if the adhesive isn't softened enough, it may break during removal.

Use a spudger to carefully lift the rear glass, starting from the area around the volume button.

• Pry up the fingerprint sensor flex cable using the edge of the spudger.
• Disconnect the prised-up cable.

Replace rear glass with caution — careful handling required.

• Remove the rear glass.
• Follow reassembly instructions to install new adhesive and rear glass.
• If replacing, transfer the rear camera bezel along with the fingerprint sensor. Refer to separate guide for detailed procedure.

Apply iOpener to the display for at least 2 minutes, reheating and reapplying as needed to loosen adhesive.

Overheating can damage components, so follow iOpener instructions carefully.

• If your display is cracked, apply clear tape over the glass to prevent further breakage and bodily harm.
• Lay overlapping strips of clear packing tape across the display to contain glass shards and provide structural integrity.

Wear safety glasses to protect eyes from flying glass particles during repair.

Apply a suction cup to the upper edge of the phone when the screen is warm.

• If the suction cup doesn't stick, try using strong tape or supergluing it in place and allowing it to cure before proceeding.
• Insert an opening pick into the gap and slide it towards the top left corner to start cutting the adhesive.

Insert another opening pick and guide it to the top right corner.

• For added protection, insert a third opening pick.

• Slide a right opening pick halfway down the side of the frame to cut adhesive.
• If cutting is challenging, reheat and reapply the iOpener.
• Place a left opening pick halfway down the frame and secure it in place.

Insert a pick on the left side, sliding down to the bottom left corner.

Be cautious of the flex cable near the power button when cutting the adhesive.

• Insert another pick at the right side to cut the remaining adhesive.
• Proceed carefully to avoid damaging nearby components.

Remove the old display by cutting adhesive on all sides.

• Lift the display upwards slowly to remove it.
• Thread the display cable through a hole in the midframe carefully.

Bent frames or leftover glue can damage the new display; inspect and replace if necessary.
