Google Pixel 4 Loudspeaker Replacement - Google Pixel 4

Step 1 | Remove the SIM card tray

Insert a SIM eject tool, bit, or straightened paper clip into the small hole on the left edge of the phone.
Press firmly to eject the SIM card tray.
Remove the ejected SIM card tray.

Step 2 | Heat the back panel glass

Never apply excessive heat — risk of display or battery damage.

Prepare an iOpener and apply it to the bottom edge of the back panel for 1 minute.
Alternatively, use a hair dryer, heat gun, or hot plate, but be cautious not to overheat the phone.

Step 3 | Apply a suction cup

Superglue the suction cup in place only as a last resort due to potential damage and loss of repair warranty.

Apply a suction cup near the heated edge, pressing down firmly to create suction.
If necessary, cover the back glass with clear packing tape for better adhesion.
Alternatively, use strong tape instead of the suction cup.

Step 4 | Insert an opening pick

Applying excessive force may damage the phone.

Pull up on the suction cup with steady force to create a gap.
If stuck, reapply heat and try again, as difficulty may be age-dependent.
Insert the point of an opening pick into the created gap.

Step 5 | Begin to slice the adhesive

Insert an opening pick under the screen's bottom edge.

Slide the pick across the bottom towards the left corner to slice the adhesive.
Continue sliding it over to the bottom right corner to fully slice the adhesive.
Leave the pick in place at the bottom right corner to keep the adhesive from re-sealing.

Step 6 | Slice the lefthand-side adhesive

Apply iOpener to the left edge of the phone for 1 minute.

Step 7

Insert opening pick under back panel, positioned directly above charge port.

Slide the pick down to the bottom left corner of the phone.

Step 8

Slide the opening pick around the bottom left corner and across the left side of the phone to slice the adhesive.

The adhesive can be very gummy; push the pick in and out in a sawing motion to help with slicing, but do not force it.

Stop when you reach the top left corner near the camera.
Leave the pick inserted at this point.

Step 9 | Slice righthand-side adhesive

Apply heat to the right edge with an iOpener for 1 minute.

Step 10

Insert a third pick on the lower right-hand side.

Slide it up towards the top of the phone, cutting the right side's adhesive.
Stop at the top right corner and leave the pick in place.

Step 11 | Slice the top-side adhesive

Sliding the third opening pick, cover the top right corner and glide it along the top edge.
The pick should slice through the remaining adhesive strip.

Step 12 | Lift up the back panel

Carefully lift the right edge of the back cover, opening it like a book.

Do not attempt to remove the panel completely at this stage — it remains attached to the phone.

Step 13

Be careful not to put stress on the attached ribbon cable when resting the back panel on the left edge of the phone.

Rest the back panel on the left edge of the phone, ensuring the ribbon cable is secure.
Power on your phone during reassembly and test all functions before re-sealing the back panel.
Power down your phone completely before continuing work.

Step 14 | Disconnect the battery

Locate the T3 Torx screws securing the battery connector shield.

Remove four 4.0 mm T3 Torx screws.
Remove one 2.1 mm T3 Torx screw.

Label and store each removed screw to ensure correct reinstallation.

Step 15

Remove the battery connector shield with a pair of tweezers.

Step 16

Never puncture the battery with a spudger.

Pry the battery connector straight up from the motherboard using the pointed end of a spudger.
To re-attach, carefully align and press down on one side until it clicks, then repeat on the other. Press only the sides, not the middle.

Step 17

Use the flat end of a spudger to carefully fold the battery cable out of the way.

Do not let it touch other components — risk of short circuit.

Step 18 | Disconnect the back panel connector

Remove the two 4mm screws using a T3 Torx driver.

Step 19

Remove the back panel connector cover using a pair of tweezers.

Step 20

Use the pointed end of a spudger to pry up and disconnect the back panel connector.

Step 21 | Remove the back panel

Remove the back panel.

If using pre-cut adhesive cards or custom-cut adhesives, follow specific reassembly guidelines to avoid damaging components.

For custom-cut adhesives, refer to the guide provided for installation steps.
If using a pre-cut adhesive card, consult its instructions and this guide for correct reassembly procedure.

Step 22 | Remove the loudspeaker

Remove one T3 Torx screw with a 4.2 mm head.
Remove one T3 Torx screw with a 4.4 mm shouldered head.

Step 23

Locate the retaining clip beneath the left frame edge.

Push the loudspeaker toward the battery using a spudger's pointed end.
A small gap between the loudspeaker and phone frame will form.

Step 24

Use tweezers to pivot the loudspeaker up and out.

If it doesn't move, try pushing it closer to the battery.

Check the adhesive gasket before installing a new loudspeaker.

Inspect for damage; re-use if in good condition, but ensure the exit hole is uncovered.
If damaged or displaced, remove and replace with pre-cut strip or Tesa tape.
