How To Replace Custom-cut Adhesive For Samsung Phones

Step 1 How To Replace Custom-cut Adhesive For Samsung Phones

• Depending on your phone model, you may not need to complete certain sections of this guide. Check your adhesive kit to see what needs to be done:
• To install the battery adhesive, follow this guide.
• To transfer and install the fingerprint sensor and gasket, start with the next step.
• To transfer and install the rear bezel, skip to step 5.
• To install the back cover support adhesive, skip to step 9.
• To install the back cover perimeter adhesive, skip to step 13.
Step 2 Fingerprint sensor and gasket adhesive




• The following three steps show how to remove and transfer the fingerprint sensor and its gasket.
• If your phone's fingerprint sensor and camera reside on a single rear bezel (like on the S9), you can transfer that bezel without removing the parts individually.
• Heat an iOpener and apply it to the fingerprint sensor for one minute.
• Use an opening tool to gently pry the fingerprint sensor at the lower seam, where it contacts the back cover.
• Do not pry at the upper seam, which is the fingerprint gasket seam.
Step 3
• If you are only replacing the fingerprint sensor and not the fingerprint sensor gasket, skip this step.
• Use an opening tool to pry the fingerprint sensor off of the gasket.
• Remove the colored plastic liner on the replacement gasket to expose the adhesive.
• Carefully align and lay the fingerprint sensor onto the sticky side of the gasket.
• Once aligned, press down firmly with your finger to bond the adhesive.
Step 4

• To affix the fingerprint sensor to the new back cover, use a custom cut adhesive, or line the perimeter of the sensor with double-sided tape such as Tesa tape.
• Align the fingerprint sensor in the back cover cutout and press down firmly with your finger to bond the adhesive.
Step 5 Rear bezel
• The following four steps show how to remove and transfer the rear bezel. The bezel supports the rear cameras, flash, and the fingerprint sensor (on some models).
• Heat an iOpener and apply it to the rear bezel for a minute.
• Starting from the outward-facing side of the back cover, push the bezel inwards with a finger to loosen the bezel from its cutout.
• Do not push too hard, or you may bend the bezel.
• Alternatively, you can pry around the bezel with an opening tool to loosen it from the back cover.
Step 6
• Remove the bezel.
• Use an opening tool and some high concentration isopropyl alcohol to remove any remaining adhesive residue on the bezel.
Step 7
• Peel away the clear plastic liner from the bezel adhesive strip to expose the adhesive.
• Carefully align the adhesive to the back cover's cutout.
• Once aligned, press the adhesive in place with your finger.
• Peel away the colored plastic liner from the adhesive to expose its surface.
Step 8
• Carefully align and set the bezel over the adhesive.
• Squeeze the bezel perimeter with your fingers to set the adhesive.
• Clean the bezel glass with a microfiber cloth.
Step 9 Back cover support adhesive
• The following four steps show how to install the back cover support adhesive(s).
• If you are replacing the fingerprint sensor or the rear bezel, be sure to complete those tasks first.
• Figure out how the support strip aligns with the surfaces by matching the adhesive strip's contours with the adhesive residue and the phone frame.
• Generally speaking, the adhesive side that's covered by a clear plastic liner should affix to the back cover, while the side that's covered by a colored liner should affix to the phone frame.
• Use an opening tool and high concentration isopropyl alcohol to remove all adhesive residue from the phone frame.
• If you are re-using the back cover, remove all adhesive residue from the back cover.
• Do not use metal tools as they will scratch the back cover's coating.
Step 10
• Peel the clear liner off of the support adhesive strip to expose the adhesive.
• Carefully lay the strip sticky side up on top of the phone frame, being careful not to touch the sticky surface.
• Align the adhesive strip on the phone frame so that the adhesive contours matches the frame's.
• If you have two small support strips, repeat the process for both strips.
Step 11
• Carefully lower the back cover onto the exposed support strips. This ensures that the adhesive is transferred onto the back cover in its proper position.
Step 12
• Remove the back cover.
• Use fingers to press the support adhesive firmly onto the back cover.
• Peel away the colored liner to expose the adhesive.
Step 13 Perimeter adhesive
• The remaining steps show how to install the back cover perimeter adhesive.
• Use an opening tool and high concentration isopropyl alcohol to remove all adhesive residue from the phone frame.
• If you are re-using the back cover, remove all adhesive residue from the back cover.
• Do not use metal tools as they will scratch the back cover's coating.
Step 14
• Peel away the clear liner from the perimeter adhesive strip to expose the adhesive.
• Hold the strip by its tabs and carefully line up a long edge of the adhesive to the edge of the back cover.
• Set the adhesive onto the back cover and press it onto the cover with your fingers.
• Peel away the colored liner from the perimeter adhesive strip to expose the adhesive.
• At this point, the back cover is prepped for sealing. Be sure to test your phone's functionality before sealing the phone.
Step 15
• To seal the phone, align and set the back cover onto the phone frame.
• Apply pressure to the phone perimeter with your fingers.
• Place some books on top of the back cover for half an hour to help the adhesive bond.
• Alternatively, you can use screen vice clamps around the perimeter of your device to set the new adhesive.
