Introduzione

This guide will show you how to remove and replace the main (rear-facing) camera of a Google Pixel 3a XL.

The Pixel 3a XL’s display panel is fragile. If you plan to reuse your screen after this repair, be sure to pay special attention to the warnings in the opening procedure.

  1. In the following steps, you will be removing the Pixel 3a's screen by cutting through the adhesive holding it in place. For reference, the backside of the screen is shown in this step. Note the narrow clearance between the edge of the screen and the OLED panel under the glass. If you plan to re-use your screen, be sure to follow the instructions below closely.

    • For reference, the backside of the screen is shown in this step.

    • Note the narrow clearance between the edge of the screen and the OLED panel under the glass. If you plan to re-use your screen, be sure to follow the instructions below closely.

    • Also note the two different seams between the body of the phone and the screen:

    • The screen seam: where the screen meets the rest of the phone. This is where the screen will separate, and where you should pry.

    • The midframe seam: where the midframe meets the body of the phone. This part is held down by screws. Do not pry at this seam.

  2. Place a suction cup on the right edge of the screen, just below the volume button. Place a suction cup on the right edge of the screen, just below the volume button.
    • Place a suction cup on the right edge of the screen, just below the volume button.

  3. In the next step you will insert an opening pick between the screen and the plastic body of the phone. If you aren't careful, the plastic opening tool can damage the fragile OLED display panel underneath the glass.
    • In the next step you will insert an opening pick between the screen and the plastic body of the phone.

    • If you aren't careful, the plastic opening tool can damage the fragile OLED display panel underneath the glass.

    • If you want to re-use your phone's screen, make sure you insert your pick at a downward angle, as shown in the second photo of this step.

    • This will ensure the opening pick slides under the OLED panel rather than between the glass and the panel, which will ruin the screen.

  4. Pull up on the suction cup with a strong, steady force to create a gap between the screen and the phone. Insert your opening pick into the gap. Stop if you feel the tip of the pick hitting against something. The pick may be pressing against the edge of the OLED panel. Angle the pick downward and try again.

  6. The adhesive holding the top and bottom edges of the screen in place is thicker, and considerably stronger than the thin strips holding the sides in place.
    • The adhesive holding the top and bottom edges of the screen in place is thicker, and considerably stronger than the thin strips holding the sides in place.

    • If you plan to reuse your screen, heat up the top edge of the phone with an iOpener, a heat gun, or a hair dryer to loosen the adhesive there before you begin slicing.

  7. Carefully slide your opening pick around the upper-right-hand corner of the screen. As shown in step one, the gap between the display and the edge of the glass screen is larger here than on the sides. If you plan to reuse your screen, take special care in this step to either keep your pick deep in the phone under the OLED display (as shown in this step's photos), or only insert it 5 mm into the device to avoid coming into contact with the display under the glass.

    • 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.

  17. Remove the screen from the phone.
    • Remove the screen from the phone.

    • Compare your new replacement part to the original part. You may need to transfer remaining components such as the speaker grille and the camera bracket to the new part.

    • To reinstall the screen:

    • Use tweezers or an opening tool to remove all traces of adhesive from the phone frame. You can use high concentration isopropyl alcohol to help with the cleaning.

    • If you plan to re-use the screen, be sure to remove all adhesive residue from the screen. Be careful with metal tools to avoid scratching the screen.

    • Apply pre-cut adhesive or double-sided tape (such as Tesa tape) to re-attach the screen to the frame.
