Follow this guide to remove the back cover for replacement, or to access the Galaxy S10+’s internals. This guide works with either the standard glass back, or the ceramic back.

  1. Samsung Galaxy S10+ Back Cover Replacement, Heat the back cover: step 1, image 1 of 3 Samsung Galaxy S10+ Back Cover Replacement, Heat the back cover: step 1, image 2 of 3 Samsung Galaxy S10+ Back Cover Replacement, Heat the back cover: step 1, image 3 of 3
    • Unplug and power off your phone before you begin.

    • Heat an iOpener and apply it to the back cover's right edge 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 both susceptible to heat damage.

    • As you wait, take a look at the image of the removed back cover and take note of where the adhesive is located.

  2. Samsung Galaxy S10+ Back Cover Replacement, Create an opening gap: step 2, image 1 of 3 Samsung Galaxy S10+ Back Cover Replacement, Create an opening gap: step 2, image 2 of 3 Samsung Galaxy S10+ Back Cover Replacement, Create an opening gap: step 2, image 3 of 3
    • Apply a suction cup to the back of the phone, as close to the center of the right edge as possible (where the adhesive is narrowest).

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

    • Insert the point of an opening pick into the gap.

    • Due to tight tolerances, this may take multiple attempts.

    • If you are having trouble creating a gap, your best bet is to apply more heat to the edge and try the previous step again.

    • You can try applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

    • Do not apply excessive force with the pick, or you will risk cracking the back cover glass.

    • Rest the heated right edge of the phone on something that is about 0.5 inches (13 mm) thick. This angles the phone for the opening tool.

    • Brace the left edge of the phone with your fingers so that the phone won't slide. Pull on the suction cup with firm pressure.

    • Press the edge of an opening tool into the seam between the back cover and the frame.

    • Slide the opening tool back and forth along the seam a few times.

  4. Samsung Galaxy S10+ Back Cover Replacement, Slice through the adhesive: step 4, image 1 of 3 Samsung Galaxy S10+ Back Cover Replacement, Slice through the adhesive: step 4, image 2 of 3 Samsung Galaxy S10+ Back Cover Replacement, Slice through the adhesive: step 4, image 3 of 3
    • Slide the opening pick along the edge of the phone, slicing through the adhesive.

    • Do not attempt to slice the adhesive holding the corners down before applying heat. If you do, you may crack the back cover.

    • Leave a pick in the seam to prevent the adhesive from re-sealing.

  5. Samsung Galaxy S10+ Back Cover Replacement: step 5, image 1 of 1
    • Apply a heated iOpener to the bottom edge of the phone for two minutes.

  6. Samsung Galaxy S10+ Back Cover Replacement: step 6, image 1 of 2 Samsung Galaxy S10+ Back Cover Replacement: step 6, image 2 of 2
    • Insert an opening pick into the right edge near the bottom right corner.

    • Carefully slide the pick around the corner. Continue cutting along the bottom edge and around the bottom left corner.

    • If the cutting feels difficult, re-apply heat to the edge before continuing.

    • Leave an opening pick in the seam to prevent the adhesive from re-sealing.

    • Continue heating and slicing around the remaining edges of the phone.

    • When cutting around corners, be sure that the corner is thoroughly heated.

    • Once you have sliced around the phone, twist an opening pick in one of the edges to help separate the back cover from the frame.

    • Lift the back cover slowly. Use opening picks to slice any remaining adhesive.

    • Remove the back cover.

    • During reassembly, this is a good point to power on your phone and test all functions before you seal the back cover in place. Be sure to power your phone back down completely before you continue working.

    • Follow this guide to reinstall the back cover, transfer and install the camera bezel, and replace the adhesive.

si le cambio la tapa trasera a mi s10 plus deja de funcionar bajo el agua?

That’s correct. The phone will not be water resistant.

Eso es correcto. El teléfono no será resistente al agua.

Arthur Shi -

then How can I keep it water-resistant?

Easy to follow guide. The iOpener worked better than a hair dryer for even heat, but it took more than I thought it would to get the back cover off.
