Google Pixel 4a Loudspeaker Replacement

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

• Press directly into the hole to eject the SIM card tray.
• Remove the ejected SIM card tray.

Locate the screen seam on the edge of the phone, where the screen separates from the rest of the device.

Do not pry at the frame seam, which is held in place by screws.

• Identify the screen flex cable and avoid inserting the opening pick deeper than instructed to prevent damage.
• Note the orange ribbon cable under the lower-right corner of the screen and insert the opening pick only as necessary to separate the screen adhesive.
• Avoid prying beyond the adhesive perimeter, which is a narrow zone surrounding the OLED panel; doing so without angling the pick will cause damage.

Apply a iOpener to the right edge of the display for one minute.

Use a heat source with caution: overheating can cause damage to the display or internal battery.

• A hair dryer, heat gun, or hot plate may also be used for adhesive softening.

If your display is badly cracked, you may need to use alternative methods to create a suction surface.

• Apply clear packing tape over the crack to aid suction cup adhesion or
• use strong tape as a direct adhesive substitute for the suction cup.
• As a last resort, superglue the suction cup to the broken screen.

Position the suction cup as close to the right edge of the screen as possible.

• Lift the suction cup with a firm, steady force.
• Insert an opening pick into the screen seam, no deeper than 1 mm from the tip.

Insert the pick 1mm into the gap, then pivot it upwards to a steep angle.

• Pivot the pick further until it's at a 45-degree angle.
• Carefully push the pick into the gap about 6mm (0.25 inches).

Stop if you feel the point of the pick hitting a ridge; the pick may be pressing against the OLED panel edge.

Slide a pick along the right edge of the screen to cut the adhesive.

Do not insert more than 1/4 inch (6 mm) or risk damaging the flex cable.

Leave the pick in the top right corner to prevent re-sealing.

Apply gentle heat if screen feels hard to slice.

• Insert another opening pick into right edge at an angle, where a gap has formed.
• Slide opening pick around bottom of phone to cut adhesive.

Be careful not to snag delicate cable under bottom-right corner of screen.

Insert only 2 mm deep and at an angle downward to prevent damage.

Leave pick inserted along bottom edge to prevent resealing.

Insert an opening pick into the bottom edge at a gap, angled to prevent OLED panel damage.

• Use the pick to cut along the left edge of the phone.
• If slicing is hard, heat the left edge for one minute and try again.

Leave the pick inserted along the left edge to prevent adhesive re-sealing.

Do not remove or damage the mesh covering the earpiece speaker on the top edge of the screen.

• Insert another opening pick into the left edge at an angle, where a gap has formed.
• Slide the pick around the top edge to cut the adhesive.
• If the screen is hard to slice, heat the top edge for one minute and try again.

Carefully lift the right edge of the screen, opening the phone like a book.

• iSclack or suction cup is not needed at this stage.
• Use an opening pick to carefully cut through any remaining adhesive.

Careful: do not apply undue stress to the ribbon cable.

• Lift the screen from the top edge.
• Swing the screen over the bottom edge until it rests glass-side down.

Peel up the black tape covering the screen connector bracket using a pair of tweezers.

If the tape is damaged, discard it and replace with electrical tape during reassembly.

• Remove the two 2.1 mm screws using a T3 Torx driver.
• Label and keep track of these screws to ensure correct reassembly.

• Remove the screen connector bracket using tweezers.

This part will be needed for reassembly.

Use the tip of a spudger to pry up and disconnect the screen flex cable.

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

  Risk of pin bending and permanent damage if misaligned

Remove the screen.

• Check if your replacement screen has speaker mesh and top edge adhesive pre-installed.
• If it doesn't, remove the larger clear liner from the top edge adhesive and apply it to the screen (not the frame), ensuring the cutout lines up with the speaker mesh.
• Follow the guide for custom-cut adhesive application.

During boot-up after reassembly, avoid touching the screen during calibration, as this may cause touch issues.

Remove the back cover by using a T3 Torx driver to take out the eight 4.3 mm screws.

Examine the photo showing the midframe components behind the back cover.

• Identify the spring contacts near the edge of the midframe.
• When using the opening pick, insert it no more than 2 mm to avoid damaging the spring contacts.

Insert the opening pick no more than 2 mm into the seam.

• Insert an opening pick between the midframe and back cover, angled downwards at a steep angle into the seam.
• Slide the opening pick along the bottom edge to release the plastic clips securing the back cover to the midframe.

Insert an opening pick at the left edge and gently slide it along the edge of the phone to disengage the plastic clips.

• The clips secure the back cover to the midframe.

Insert an opening pick at one edge of the phone and slide it around the top and right edges to release the remaining adhesive clips.

Rotate the back cover from the bottom up over the top and around the back of the phone.

Avoid putting pressure on the attached ribbon cables as you place the midframe on the back cover.

Remove the motherboard bracket using a T3 Torx driver.

• Remove three 2.9 mm-long black screws.
• Remove three 2 mm-long screws.
• Remove one 4.1 mm-long screw.

Use the tip of a spudger to gently pry the motherboard bracket loose at the upper-right and lower-right corners.

Remove the motherboard bracket with a pair of tweezers.

Disengage the battery cable using a flat-ended spudger.

Disconnect the flex cables connecting the fingerprint sensor and buttons using the tip of a spudger.

Remove the back cover.

• Remove the two 4.1 mm screws using a T3 Torx driver.

Insert the spudger tip under the loudspeaker assembly.

Avoid puncturing the white membrane for future reusability.

• Flip the loudspeaker over and rest it on top of the battery.

Disengage the antenna flex cable from the loudspeaker assembly using the pointed end of a spudger.

Be cautious when removing the loudspeaker assembly — avoid damaging its white membrane.

• Pry up the loudspeaker assembly from the adhesive underneath with care.
• Avoid puncturing the white speaker membranes to ensure reuse potential.
• Once loose, completely remove the loudspeaker assembly.
