简介

This guide shows how to remove and replace the glass back panel for your Pixel 3 XL.

Depending on your replacement part, you may need to transfer additional parts to your new back panel. This guide includes additional steps to transfer the fingerprint sensor, flash diffuser, and camera bracket to a replacement back panel. Replacing or swapping the NFC antenna is not included in these steps.

  1. Heat an iOpener and apply it to the right edge of the back panel for a minute. A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage. While you wait, note the following areas on the back panel:

    • While you wait, note the following areas on the back panel:

    • Strong adhesive—there are large patches of adhesive near the bottom of the phone.

    • Fingerprint sensor cable—be careful not to slice through the cable as you pry

  2. Apply a suction cup to the heated edge of the back panel, as close to the edge as possible. Pull up on the suction cup with strong, steady force to create a gap. Depending on the age of your phone, this may be difficult. If you are having trouble, apply heat to the edge and try again.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply heat to the edge and try again.

    • Insert the point of an opening pick into the gap.

  3. Slide the opening pick along the right edge to slice through the adhesive. The adhesive gums up and becomes hard to slice once it cools. If that happens, re-apply heat to the edge to make slicing easier. Once you have sliced through the edge, leave an opening pick in the seam to prevent the adhesive from re-sealing.

  5. Use an opening pick to slice around the bottom right corner and continue along the bottom edge of the phone. Work slowly as you slice around the corner to prevent the panel from cracking. If the slicing becomes hard, re-apply heat. Leave a pick in the edge to prevent the adhesive from re-sealing.

  6. Continue heating and slicing the remaining edges of the phone. Be careful as you slice along the left edge of the phone. If your pick feels like it's stuck near the top, you may have snagged the fingerprint sensor. Retract the pick out of the seam slightly and try again. Be sure to cut through the thick portions of adhesive near the bottom and right edge of the phone.

    • Gently pry up the right edge of the back panel.

    • Use an opening pick to slice through any remaining adhesive along the edges.

  9. Swing the right edge of the back panel upwards and rest the flipped panel along the left side of the phone. Be sure to maintain slack on the fingerprint sensor cable and prevent it from being pinched. During reassembly, this is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

What’s the flat pice that surrounds the fingerprint sensor? It appears to have two pieces that connect with a terminal on the logic board.

Is it the NFC reader?

Correct! That is the NFC coil.
