简介

This repair guide was authored by the iFixit staff and hasn’t been endorsed by Google. Learn more about our repair guides here.

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

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

    • Heat an iOpener and apply it to the right edge of the back cover 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 cover:

    • 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

    • Apply a suction cup to the heated edge of the back cover, 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.

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

    • 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.

    • Leave a pick in the edge to prevent the adhesive from re-sealing.

    • 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.

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.

Grant Pauli - 回复

Is it the NFC reader?

Grant Pauli -

Correct! That is the NFC coil.

Arthur Shi -

I successfully installed the screen but accidentally broke off the gold tab sticking up from the mother board shield. It can be seen on the picture of step 11 next to the NFC connectors. Do you know what this is for and how it will affect the function of the phone?

Sal Arias - 回复

Hi Sal!

That tab looks to be a grounding clip, which would normally touch the fingerprint sensor bracket. I don’t think it is vital for daily function.
