    • Insert a SIM eject tool, bit, or straightened paper clip into the SIM card tray hole on the top edge of the phone.

    • Press the SIM eject tool into the SIM card tray hole to eject the SIM card tray.

    • Remove the SIM card tray.

    • If you accidentally inserted the SIM eject tool into a microphone hole, don't worry! You most likely didn't damage the microphone.

  2. Samsung Galaxy S21+ USB-C Charging Port and Daughterboard Replacement, Heat the bottom edge: stap 2, afbeelding 1 van 1
    • Be sure to power off your device before you begin your repair.

    • Heat an iOpener and apply it to the bottom 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 both susceptible to heat damage.

    • Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.

    • If the back cover is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the back cover with the suction handle to create a small gap between the back 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 you created.

    • 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. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.

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

Conclusie

To reassemble your device, follow the instructions in reverse order and perform the opposite actions, e.g., "reattach" instead of "removing." Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.

After you've completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and follow the Samsung Self-Repair document (beginning page 10) to make sure your device is fully functional.

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