Drop your S8? Keep it in the same pocket as your keys?
Chances are the glass back is already shattered. Use this guide to replace the back panel glass on the Samsung Galaxy S8.
If your replacement part does not come with adhesive mounted on it, you will also need to purchase adhesive for the rear glass and the fingerprint reader. You can buy pre-cut adhesive, or thin high-bond tape.
- Place the iOpener in the center of the microwave.
- Heat the iOpener for thirty seconds.
- Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.
- Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.
- Apply a heated iOpener to a long edge of the S8 for about 2 minutes.
- In the following steps you will be cutting through the adhesive around the edge of the rear glass panel.
- The adhesive on the rear case is laid out as seen in the first image.
- The prying pattern as seen from the outside of the phone is as follows:
- Thick portions of adhesive
- Thin areas of adhesive
- Avoid prying here, to protect the fingerprint sensor.
- Once the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge.
- Lift on the suction cup, and insert a halberd spudger, or opening pick, under the rear glass.
- Once you have the tool firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.
- Slide an opening pick or the blade of a Halberd spudger down the side of the phone, separating the adhesive.
- Repeat the previous heating and cutting procedure for the remaining three sides of the phone.
- Leave an opening pick on each side as you continue to the next to prevent the adhesive from resealing.
- Use the opening picks to slice through any remaining adhesive and open the phone slightly.
- Remove the glass from the phone.
- First use tweezers to peel away any remaining adhesive from both the back cover and the phone's chassis.
- Then, clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth. Swipe in one direction only, not back and forth. This will help prep the surface for the new adhesive.
- Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.
- After installing the rear cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.
- Reheat an iOpener and apply it to the fingerprint sensor mounted to the rear glass.
- Push the fingerprint sensor off of its adhesive from the outside of the glass.
- If the sensor is stubborn, gently slide a halberd spudger under the plastic backing to loosen the adhesive before pushing.
- If the fingerprint sensor adhesive is intact, it may be reused, but if damaged at all you should remove the old adhesive and apply replacements.
- After removing the old adhesive, clean the edges of the fingerprint sensor with high concentration isopropyl alcohol (at least 90%), then apply the new adhesive.
After reapplying adhesive, follow these instructions in reverse order to reassemble your device.
