This guide shows how to remove and replace the loudspeaker for the Pixel 3a. During removal, a loudspeaker corner is pinned under the right squeeze sensor’s support bracket. This guide shows how to loosen the support bracket in order to wiggle the loudspeaker out. Alternatively, you can remove the motherboard and the support bracket first to gain unrestricted access to the loudspeaker.

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 procedure requires re-attaching the proximity sensor connector, which requires some patience and finesse.

  1. 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.
    • 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 LCD.

  2. Heat an iOpener and apply it to the right edge of the display for a minute.
    • 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.

  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.
    • 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.

  4. This step shows how to insert the pick without damaging the LCD 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.

    • 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 LCD panel. Angle the pick and try again.

  5. Slide the pick along the right edge, slicing through the adhesive. Do not insert the pick more than 1/4" (6 mm), or you may damage the screen's flex cable. Leave a pick in place to prevent the adhesive from resealing.
    • Slide the pick along the right edge, slicing through the adhesive.

    • Do not insert the pick more than 1/4" (6 mm), or you may damage the screen's flex cable.

    • Leave a pick in place to prevent the adhesive from resealing.

  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.
    • 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.

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

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

  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.
    • 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.

  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.

Is there a guide to put everything back in place, because I'm am not confident in working backwards. Also are all the tools used included in the essentials kit that ifixit sells

Jerry Chen - Ответить

Hi Jerry,

There is unfortunately no separate guide to put everything back in place. Just take it slow and make note of all the push-pin reminder bullets.

The essentials kit does not include an iOpener or the T3 bit that’s necessary for the repair.

Arthur Shi -

If I am reusing the screen do I need to apply some glue or just heat it up and attach it back to the body.
