Samsung Galaxy S20 Earpiece Speaker Replacement

Insert a SIM card eject tool, bit, or a straightened paperclip into the hole on the SIM tray.

• Locate the hole at the top edge of the phone next to the plastic antenna band.
• Press in firmly to eject the tray. Note: If inserted incorrectly, do not worry as the microphone and ingress gasket are protected.

Replace the SIM tray immediately if the rubber gasket is damaged or missing.

• Remove the SIM card tray.

• The SIM card will fall out; handle it carefully.
• When reinserting, ensure the SIM card is in the correct orientation with the tray.

Unplug your phone and power it off.

• iOpener: Heat and apply to bottom edge of back cover for two minutes.
• Alternative methods: Hair dryer, heat gun, or hot plate can be used, but avoid overheating the phone as display and internal battery are susceptible to damage.

Apply suction cup near center of bottom edge to avoid damage.

• Use clear packing tape for cracked displays if necessary.
• Pull on suction cup firmly and steadily to create gap between back cover and frame.

Tight tolerances may require multiple attempts with iOpener and suction cup.

• Reheat edge and try again if initial attempt fails.
• Do not apply excessive force to pick, or risk cracking back cover glass.

Insert opening pick into gap created by suction cup.

Never attempt to cut the adhesive near the corners, as it may crack the glass panel.

• Slide a pick along the bottom edge, moving it back and forth to slice through the adhesive.
• Leave the pick in place to prevent the adhesive from resealing.

Apply heat to the left edge of the iOpener target area for 2 minutes using a heated iOpener.

Apply a suction cup to the phone's back, as close to the left edge as possible.

• Pull 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, ensuring only the tip is under the glass's edge due to its curve.

This may require multiple attempts due to tight tolerances. If struggling, apply more heat or try adding a few drops of high concentration (over 90%) isopropyl alcohol into the seam.

Avoid excessive force with the pick, as it may crack the back cover glass.

Insert the pick further into the gap between the glass and the back cover.

Tilt the pick downward to avoid applying pressure on any internal components.

Continue until the adhesive is fully separated, allowing you to remove the back cover.

Slide a pick along the left edge of the phone, separating the back cover's adhesive.

Be cautious when crossing the ridge above the volume and power buttons: cracking the glass is possible due to its cutout.

Leave your pick under the top left corner of the glass after removal, preventing re-adhesion.

Avoid overheating the device — display and internal battery may be damaged.

• Apply a heated iOpener to the right edge of the back cover for two minutes.
• Alternatives: use a hair dryer, heat gun, or hot plate (but keep temperatures in check).

• Attach a suction cup to the phone's back, near the center of the right edge.
• Pull on the suction cup firmly until a gap forms between the back cover and frame.

Slide a pick along the right edge of the phone to separate the adhesive.

Keep the pick under the glass near the top to prevent resealing.

• If other picks fall free, set them aside and continue with caution.

Heat an iOpener and apply it to the top edge of the back cover for 2 minutes.

The curved glass near the corners of the back cover is prone to cracking.

• Slide a pick along the right edge of the device around the top right corner.
• Continue slicing along the top edge to the top left corner to separate the back cover adhesive.

Reapply heat if the process becomes difficult.

Slowly lift the back cover, using opening picks to carefully slice any remaining adhesive.

Power on your phone and test all functions before sealing it up, then power down completely.

• Remove any adhesive chunks with a pair of tweezers or your fingers, applying heat if necessary.
• If using custom-cut adhesives, follow the dedicated guide.
• If using double-sided tape, consult the relevant guide for reassembly instructions.

Remove the motherboard bracket using a Phillips #00 screwdriver.

• Remove five screws, each 4 mm long.
• Keep track of each screw for reinstallation purposes.

Use a pair of tweezers to gently pull up and unclip the motherboard bracket from the plastic midframe.

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

Peel the wireless charging coil away from the device with care.

• Remove the wireless charging coil.
• The coil uses spring contacts; no connectors need be disconnected.

During reassembly, securely fasten motherboard bracket screws first to align the coil, then press firmly down on the rest of the coil to secure it in place.

Be cautious of dislodging nearby components when removing connectors.

• Use a spudger to pry up and disconnect the battery connector.
• Avoid touching or moving small surface-mounted parts near the socket.

Remove the five 4 mm screws using a Phillips #00 screwdriver.

• The screws are securing the loudspeaker and lower midframe.

Locate the notch at the top left corner of the midframe.

• Remove the loudspeaker and lower midframe.

Use a spudger to disconnect the main and auxiliary flex cables from the daughterboard.

If re-attaching press connectors, align carefully and press down on one side until it clicks into place, then repeat on the other. Never press down on the middle.

• When inserting a press connector, risk of pin damage from misalignment exists.

Use a spudger to gently pry up and disconnect the main and auxiliary flex cables from the motherboard.

Remove the main flex cable by gently peeling it away from its connectors.

Avoid pulling on the cable itself to prevent damage to the connector pins.

Next, carefully lift out the auxiliary flex cable.

Use a spudger to pry up the main display flex cable from the motherboard.

Peel up the display flex cable gently and bend it out of the way.

• Motherboard side:
• Bend the display flex cable away from the motherboard.
• Battery side:
• Bend the display flex cable around the battery connector.

Remove the four 4 mm-long upper midframe screws using a Phillips #00 screwdriver.

Insert the point of a spudger into the notch on the right side of the upper midframe.
