Introduction

Follow this guide to remove or replace the back cover in your Samsung Galaxy S23 Ultra.

Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.

    • Heat an iOpener and apply it to the right edge of the back cover for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are susceptible to heat damage.

    • While you wait for the adhesive to soften, note the following:

    • There's adhesive securing the back cover around the perimeter of the frame.

    • The adhesive is strongest in the bottom right and top left corners.

    • Apply a suction handle to the back cover, as close to the center of the right edge as possible.

    • Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap.

    • Grab and remove the back cover.

    • If your cover is still sticking to the frame, slide an opening pick around the perimeter until the cover completely separates.

    • During reassembly:

    • This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

    • Remove any adhesive chunks with a pair of tweezers or your fingers. Apply heat if you're having trouble separating the adhesive.

    • If you're using custom-cut adhesives, follow this guide.

    • If you're using double-sided tape, follow this guide.

Conclusion

Compare your new replacement part to the original part—be sure to transfer remaining components and remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
