How to Do a S8 Rear Glass Replacement

You can’t have a smartphone today without breaking the glass at least once. It’s like an unwritten rule that no one really wants to admit. But let’s be honest, how many people do you really know that have never smashed their phone? Probably none! It happens all the time which is why it’s so important to learn how to do a S8 rear glass replacement on your own.


Crash Course on S8 Rear Glass Replacement

In this guide, you’ll be learning how to remove the rear glass cover on a Samsung Galaxy S8 because the shattered glass simply isn’t working for you anymore.

Difficulty: Easy

Time: 15 minutes


Tools Needed to Replace S8 Rear Glass

  • iOpener
  • Suction Handle
  • Halberd Spudger
  • Opening Picks


  • Galaxy S8 Rear Glass Panel
  • Galaxy S8 Aftermarket Blank Rear Glass Panel
  • Galaxy S8 Rear Cover Adhesive
  • Galaxy S8 Rear Camera Bezel Lens Cover
  • Tesa 61395 Tape


Instructions for S8 Rear Glass Replacement


Step One: iOpener Heating

  1. Clean your microwave and remove any debris that may get stuck to the iOpener
  2. Place iOpener in microwave and make sure the plate spins freely to deter the iOpener from getting overheated and burnt
  3. Heat for 30 seconds and reheat as needed throughout the repair procedure


Step Two: Rear Glass Assembly

  1. Apply the heated iOpener to a long edge on your S8 for approximately 2 minutes
  2. Once the adhesive is softened, continue to next step


Step Three: Open the Rear Glass

  1. Once back panel is warm, place the suction cup onto the rear glass as close to the edge as possible without going near the curved edges
  2. Carefully lift the suction cup and insert the halberd spudger or opening pick firmly under the rear glass

Since the S8 has curved glass, you’ll be pushing the pick up into the phone as opposed to inserting it parallel to the plane of the phone.

Step Four: Open Up

  1. Reheat iOpener and apply to soften the adhesive
  2. Slowly slide the Halberd spudger down the sides of the phone to separate the glue
  3. Do so for all four sides, keeping an opening pick in each
  4. Remove the glass from the phone

Make sure the orange cable with a blue connector is disconnected. You can do so by taking a peek inside as you lift.

If you feel like the cable is snagged or seems to be taut, stop, reread this Digital Supply USA guide and disconnect before moving onto the next step.


Step Five: Clean Up

  1. Remove the old adhesive from the S8
  2. Clean the edges with isopropyl alcohol


Step Six: Transfer the Fingerprint Sensor

  1. Reheat iOpener and apply to fingerprint sensor which can be found on the rear glass
  2. Remove the fingerprint sensor from the adhesive by pushing from the exterior of the glass
  • This is easier than it sounds but you can use a Halberd spudger if you’re having difficulties
  • Repeat step five
  • If the adhesive used on the finger sensor is damaged, you will have to replace it.


    Then, go through the steps from the bottom up to put your S8 Rear Glass Replacement back on! Before you know it, you’ll have a brand new (looking) phone! Shop all your S8 parts today at Digital Supply USA.
