Introduction

Follow this guide to remove and replace a broken earpiece speaker for the Pixel 3a.

The procedure is similar for the Pixel 3a XL except this step, where the microphone contacts are on the left instead of the right. If you’re working on the Pixel 3a XL, follow our Pixel 3a XL guides for disassembly.

The Pixel 3a’s unreinforced display panel is fragile. If you are reusing the screen, be sure to pay special attention to the warnings in the opening procedure.

The trickiest part of the procedure is re-attaching the light sensor, which requires some patience and finesse.

What you need

Step 1

              Screen

Take note of the two seams on the phone:
Screen seam: This seam separates the screen from the rest of the phone. This is where you should pry.
Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.
Before you begin prying, note the following areas on the screen:
Screen flex cable: Do not pry deeper than instructed, or you risk damaging this cable.
Adhesive perimeter: Prying beyond the narrow perimeter without angling the pick will damage the display panel.

Step 2

Heat an iOpener and apply it to the right edge of the display for a minute.
You can choose to skip this step since the Pixel 3a’s screen adhesive is not very strong. Heating it, however, will decrease the chance of cracking the screen.

Step 3

Place a suction cup near the right edge of the screen.
Pull on the suction cup with strong steady force.
Insert the pick into the gap, no more than 1 mm.

Insert the pick into the gap, no more than 1 mm.

Step 4

This step shows how to insert the pick without damaging the OLED panel. Do this before you slice either long edges of the phone.
With the pick 1 mm in the gap, pivot the pick upwards to a steep angle.
At this angle, carefully push the pick into the gap about 1/4" (6 mm). The pick should slide in below the OLED panel.
Stop if you feel the point of the pick hitting a ridge. The pick may be pressing against the edge of the OLED panel. Angle the pick and try again.

Step 6

As you slice around the bottom edge of the phone, do not insert the pick more than 1/4" (6 mm).
Slide the pick around the bottom right corner to slice through the adhesive.
If the corner feels hard to slice, apply a heated iOpener to the corner for a minute and try again.
Continue slicing along the bottom edge of the phone and around the left corner.

If the corner feels hard to slice, apply a heated iOpener to the corner for a minute and try again.

Continue slicing along the bottom edge of the phone and around the left corner.

Step 7

Slice through the left edge of the phone, making sure to properly angle the pick below the OLED panel and insert it in no more than 1/4" (6 mm).
To angle the pick below the OLED panel, insert the point of the pick no more than 1 mm in, angle the pick upwards, and then slowly push the pick in 1/4".

To angle the pick below the OLED panel, insert the point of the pick no more than 1 mm in, angle the pick upwards, and then slowly push the pick in 1/4".

Step 8

Slice along the top edge while keeping the pick no more than 5/16" (8 mm) in.

Step 9

With all of the edges cut, carefully hinge open the right edge of the screen.
Do not remove the screen. It is still attached to the phone by a flex cable near the left edge.
Use an opening pick to carefully cut through any remaining adhesive.

Step 10

With all of the adhesives cut, flip the attached screen glass side down and rest it on top of the phone. The screen flex cable should be loosely arched.

Step 11

Carefully peel the black tape covering the screen connector bracket.
If it is in good condition, you can re-use this tape during reassembly. Otherwise, replace it with a piece of electrical tape.
Remove the two 4.4 mm long T3 screws securing the screen connector bracket.

Step 12

Use the point of a spudger to pry up and disconnect the screen flex cable.
When you disconnect connectors like these, be careful not to dislodge the small surface-mounted components surrounding the socket.
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.

Step 13

Remove the screen.
Carefully compare your replacement screen with your original part. You may need to transfer additional components (such as the speaker mesh) to the new part.
To reinstall the screen:
Follow this guide if you are using custom-cut adhesives.
If you are using double-sided tape such as Tesa tape, follow this guide.
During the boot-up process after reassembly, the screen will go through a calibration sequence. Do not touch the screen during this process, as it could result in improper touch calibration and create touch issues.

Step 14

              Plastic Midframe

Remove the fourteen T3 screws of the following lengths securing the plastic midframe:
Twelve 4.3 mm silver T3 screws
Two 4.3 mm black T3 screws
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

Step 15

The midframe is still held in place by plastic clips.
Insert an opening pick into frame seam at the bottom of the phone. This seam sits between the plastic midframe and the back cover.
Slide the pick along the seam to release the clips holding the plastic midframe.

Step 16

Slide the opening pick along the left and right edges of the phone to release the midframe clips.
Lift the bottom edge of the plastic midframe up but do not remove the midframe. The midframe is still tethered to the phone by the fragile proximity sensor cable at the top edge.
To reinstall the plastic midframe, align the midframe to the back cover, and squeeze the perimeter of the phone with your fingers to snap the clips back into position.

Step 18

This step shows how to reconnect the proximity sensor during re-assembly.
Align the top edge of the plastic midframe with the phone.
Use the point of a spudger to carefully align and push the proximity sensor connector onto the motherboard socket.
This takes a bit of patience and finesse. Once you have the connector in place, you can also use a finger to gently press the connector onto the socket.
Alternatively, you can remove the proximity sensor from the midframe to reattach it to the motherboard first.
Use the point of a spudger to carefully pry the proximity sensor out of its recess on the midframe. The sensor is lightly adhered to the midframe.
Remove the sensor from the midframe. Attach the sensor connector onto its motherboard socket.
Thread the sensor cable through the midframe and reposition the sensor in the recess. Press down with your finger to adhere the sensor back onto the midframe.

Step 20

Remove the earpiece speaker.
When installing a replacement earpiece speaker, be sure that it is properly oriented. The two gold contact springs should be facing up, on same side of the midframe as the copper shield (the right side of this step’s photo).

Just to report back on this guide, my Pixel 3a XL actually has the gold contacts for the earphone on the opposite side than shown here. Looks to be the reason for it to not work in the first place. Unfortunately I damaged my screen during the repair by pressing too far into the bottom ribbon connector, splitting it, or damaging it in some way it will not function anymore. Just flickers.

Thanks for the guide!

Eugeniu Plamadeala - May 9, 2021

Same problem in my case. I cracked the screen while trying to remove old adhesive one the edges.

Mike Walko - Aug 28, 2021

Same issue on my 3aXL- was confused by this guide as a result, had to take my phone apart a few times for testing before I figured out the problem- I was about to order another replacement speaker.

Overall, great guide- a small note for 3a XL owners would be very helpful! Had i not followed the guide on that one step I’d be 45 minutes ahead haha

Arthur Shi - Aug 30, 2021

Thanks for the feedback! Yes, the earpiece contacts for the 3a XL is indeed on the left instead of the right. I’ll add a note in the intro to highlight that.

Hansjoerg Hofer - Nov 3, 2021

Hallo, kann mir vielleicht jemand sagen wie die Staub Abdeckung oben beim Display heißt ? Oder als Ersatzteil zu finden ist ?

Vielen Dank
