Samsung Galaxy S21 Loudspeaker Replacement

Power off your device completely.

• Apply a preheated iOpener to the bottom edge of the back cover for two minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate, but be cautious not to overheat and damage components such as the display, internal battery, or plastic back cover.

Apply a suction cup to the back of the phone, centered on the bottom edge.

• Pull up on the suction cup with strong force until a gap forms between the cover and frame.

• If difficult, apply more heat and retry.

• Insert an opening pick into the gap, but only up to 5 mm to avoid damage.

Apply gentle pressure, moving the pick back and forth along the device's bottom edge to break down the adhesive.

Never remove the pick until you have successfully separated the components, as resealing of the adhesive may occur.

Apply a iOpener to the left edge of the back cover and heat for 2 minutes.

Apply a suction cup to the phone's back, near the left edge.

• Pull up on the suction cup with strong, steady force to create a gap between the back cover and frame.
• Insert an opening pick into the gap, but limit insertion depth to 5 mm to avoid damage.

Avoid cutting past the camera area — risk of damaging the plastic.

• Slide an opening pick along the left edge towards the bottom left corner.
• Stop before reaching the camera shell and back cover junction.
• Leave the pick in place to prevent adhesive resealing.

Heat the iOpener and apply it to the back cover's right edge for 2 minutes.

• Attach a suction cup to the phone's back near the center of the right edge.
• Pull up on the suction cup with strong force to create a gap between the back cover and frame.

Insert an opening pick into the gap, but do not insert it more than 3 mm to avoid damaging the secondary interconnect cable.

• Slide a pick along the right edge of the back cover, moving it back and forth to break the adhesive.
• Leave the pick in place to prevent the adhesive from resealing.

Insert a right-edge opening pick into the top-right corner of the phone.

• Rotate the pick around the edge of the phone, working carefully not to apply too much pressure.

• Do not insert the pick more than 5 mm to avoid damaging internal components.

This procedure can be repeated for each corner except the top-left where the rear-facing camera is located.

• Position the top-most opening pick near the camera shell.
• Place the left-edge pick similarly and repeat the process.

Apply heat from an iOpener to the camera shell for 2 minutes.

Rotate the back cover counterclockwise to create a 5 mm gap between the camera shell and frame.

• Insert the pick up to 5 mm to avoid scratching the camera.
• Insert an opening pick in the created gap.

• If this method doesn't work, proceed with caution as alternative methods may require specialized tools.

Risk of cracking the plastic back cover.

• Slide the picks toward the camera shell so they are under the corners of the back cover.
• Moved the picks along the bridge between the back cover and the camera shell, creating a gap.

Apply heat as necessary due to strong adhesive bonding.

• Insert an opening pick between the camera shell and frame.
• Gently pry apart the components using a gentle sawing motion, working around the entire perimeter.

Risk of tool damage: be cautious of the plate under the phone's flash.

• Cut through adhesive on the right side of the camera using a suitable tool.
• Angle the pick downward to avoid getting stuck on the surrounding plate.

Line up the opening pick with your phone's flash.

• Insert the pick slowly, being careful not to touch the flash's plate.
• The plate may feel like a resistance similar to adhesive; keep the pick angled downward to avoid sliding into it.
• Slice the adhesive to the right of the camera.

Remove the back cover.

• If it's still stuck, slide a pick around the edges until it separates completely.
• During reassembly:
• Power on your phone and test functions before sealing. Then power down completely.
• Remove adhesive chunks with tweezers or fingers.

• Use high concentration (over 90%) isopropyl alcohol to wipe away any remaining residue, risking damage otherwise.

• For Samsung custom-cut adhesives, follow the provided guide.
• For double-sided tape, follow its dedicated guide instead.

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

• Maintain a record of each removed screw for reinstallation purposes.
• Ensure that each screw is replaced exactly where it was originally located.

Use a pair of tweezers to gently lift up and release the motherboard bracket from its frame.

Do not remove the bracket completely yet, as it is still secured to the wireless charging coil.

To avoid damaging the socket or surrounding components, carefully pry up the battery press connector with a spudger under its edge.

• Use tweezers or your fingers to hold the motherboard bracket out of the way.
• Pry only under the edge of the connector for safety.

When re-attaching press connectors, align and press down on one side until it clicks into place, then repeat on the other. Never press in the middle to avoid pin bending and permanent damage.

• Hold the motherboard bracket aside.
• Pry up and disconnect the wireless charging coil's press connector with a spudger.

Peel the wireless charging coil away from the phone using your fingers.

• During reassembly, refasten the motherboard bracket screws first.
• Firmly press the wireless charging coil into place and let it adhere.

Remove the six 4mm x #1 Phillips screws securing the loudspeaker using a Phillips screwdriver.

Locate the notch in the top-left corner of the loudspeaker.

• Insert a spudger into the notch and gently pry up.
• The clips holding the loudspeaker in place should release.
• Remove the loudspeaker.
