Samsung Galaxy S9 Plus Fingerprint Sensor and Camera Lens Cover Replacement

Switch off your phone.

• Apply an iOpener for at least two minutes to loosen rear glass adhesive.
• If needed, repeat this step several times during back cover removal.

Use extreme caution when applying heat: the AMOLED display and internal battery are susceptible to damage.

If iOpener is insufficient, use a hair dryer, heat gun, or hot plate. However, be careful not to overheat your phone.

Prying or slicing in this area may damage the fingerprint sensor flex cable.

• Identify and slice through thick portions of adhesive as shown.
• Similarly, target thin areas of adhesive for cutting.

Apply strong tape or superglue to the suction cup if rear glass is cracked.

• Press a suction cup onto the back cover.
• Lift the bottom edge with your suction cup, creating a slight gap.
• If needed, apply more heat and try again as adhesive cools quickly.
• Insert an opening pick in the gap and slide it to the bottom right corner.

Insert a second opening pick near the top right edge and slide it down to the bottom left corner.

• Insert a third opening pick at the bottom end of the phone, positioning it for rear glass removal.
• This opening pick will remain in place throughout the procedure to prevent adhesive resealing.

Insert the opening pick into the bottom left corner.

• Slide the pick along the left side, stopping halfway up.
• Leave the pick in place without moving it further.
• Repeat this process for the bottom right corner, leaving the pick stationary.

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

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

Do not fully open the phone yet, as the flex cable for the fingerprint reader is still connected.

• Lift the glass at this point using care.
• Pry up the fingerprint sensor flex cable with a spudger's edge.
