Introduction

Use this guide to remove or replace the earpiece speaker in your Samsung Galaxy S21.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

  1. Samsung Galaxy S21 Earpiece Speaker Replacement, Heat the bottom edge: step 1, image 1 of 1
    • Completely power off your phone before you begin.

    • Heat an iOpener and apply it to the back cover's bottom 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, internal battery, and plastic back cover are both susceptible to heat damage.

    • Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.

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

    • Depending on the age of your phone, this may be difficult. If you're having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.

    • Only insert the pick up to 5 mm, as you may damage internal components if you go further.

    • There's additional adhesive to the right of the camera that you need to cut through.

    • There's a plate on the back cover surrounding the phone's flash that the pick can get stuck on:

    • Angle the pick downward to avoid any damage.

  17. Samsung Galaxy S21 Earpiece Speaker Replacement: step 17, image 1 of 3 Samsung Galaxy S21 Earpiece Speaker Replacement: step 17, image 2 of 3 Samsung Galaxy S21 Earpiece Speaker Replacement: step 17, image 3 of 3
    • Line up the opening pick's tip with your phone's flash

    • Insert the pick slowly, making sure to avoid the flash's plate.

    • The plate's resistance can feel similar to adhesive. Angle the pick downward to keep the pick from sliding into the plate.

    • Slice the adhesive to the right of the camera.

  18. Samsung Galaxy S21 Earpiece Speaker Replacement, Remove the back cover: step 18, image 1 of 2 Samsung Galaxy S21 Earpiece Speaker Replacement, Remove the back cover: step 18, image 2 of 2
    • Remove the back cover.

    • If your back cover is still sticking to the frame, slide the pick around the edges of the phone until the back 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. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.

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

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

    • Use a Phillips screwdriver to remove the five 4 mm-long screws securing the motherboard bracket to the frame.

    • Throughout this repair, keep track of each screw, and make sure it goes back exactly where it came from.

  19. Samsung Galaxy S21 Earpiece Speaker Replacement, Unclip the motherboard bracket: step 20, image 1 of 2 Samsung Galaxy S21 Earpiece Speaker Replacement, Unclip the motherboard bracket: step 20, image 2 of 2
    • Use a pair of tweezers to gently pull up and unclip the motherboard bracket from the frame.

    • Do not completely remove the bracket yet, as it's still attached to the wireless charging coil.

  20. Samsung Galaxy S21 Earpiece Speaker Replacement, Disconnect the battery: step 21, image 1 of 2 Samsung Galaxy S21 Earpiece Speaker Replacement, Disconnect the battery: step 21, image 2 of 2
    • While using tweezers, or your fingers, to hold the motherboard bracket out of the way, use a spudger to pry up the battery press connector.

    • Take care to pry only under the edge of the connector to prevent damaging the socket itself and surrounding components.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

    • The wireless charging coil is secured to the phone with light adhesive.

    • Use your fingers to gently peel the wireless charging coil away from the phone.
