Google Pixel 3 XL Fingerprint Sensor Replacement

你所需要的

  1. Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: 步骤 1 中的图像 1,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: 步骤 1 中的图像 2,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: 步骤 1 中的图像 3,3
    • 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

  2. Google Pixel 3 XL Fingerprint Sensor Replacement, Create a gap under the back cover: 步骤 2 中的图像 1,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Create a gap under the back cover: 步骤 2 中的图像 2,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Create a gap under the back cover: 步骤 2 中的图像 3,3
    • 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.

  3. Google Pixel 3 XL Fingerprint Sensor Replacement, Loosen the right edge adhesives: 步骤 3 中的图像 1,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Loosen the right edge adhesives: 步骤 3 中的图像 2,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Loosen the right edge adhesives: 步骤 3 中的图像 3,3
    • 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.

    • Apply a heated iOpener to the bottom of the back cover for a minute.

  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. Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the remaining edges: 步骤 6 中的图像 1,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the remaining edges: 步骤 6 中的图像 2,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the remaining edges: 步骤 6 中的图像 3,3
    • 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.

  7. Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the leftover adhesive: 步骤 7 中的图像 1,1
    • Gently pry up the right edge of the back cover.

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

  8. Google Pixel 3 XL Fingerprint Sensor Replacement, Swing open the back cover: 步骤 8 中的图像 1,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Swing open the back cover: 步骤 8 中的图像 2,3 Google Pixel 3 XL Fingerprint Sensor Replacement, Swing open the back cover: 步骤 8 中的图像 3,3
    • Swing the right edge of the back cover 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.

    • During reassembly, follow this guide to install custom-cut adhesives for your back cover.

    • If you replaced the fingerprint sensor, you'll need to use this software tool to make the phone recognize the new sensor.

  9. Google Pixel 3 XL Fingerprint Sensor Replacement, Remove the fingerprint sensor tape: 步骤 9 中的图像 1,1
    • User tweezers to carefully peel up the yellow tape over the fingerprint sensor connector.

    • Use the point of a spudger to carefully flip up the black lock bar on the fingerprint sensor's ZIF socket.

    • Grasp the cable's tab with your fingers or tweezers and gently walk the flex cable out of the socket.

    • To prevent shorting, be careful not to touch the metal contacts on the flex cable with your tweezers.

  11. Google Pixel 3 XL Fingerprint Sensor Replacement, Remove the back cover: 步骤 11 中的图像 1,1
    • Remove the back cover.

    • Follow this guide to correctly apply new back cover adhesive.

    • Insert the edge of an opening tool underneath the square portion of the fingerprint sensor and slowly pry up to loosen the sensor.

    • Continue prying around the perimeter of the fingerprint sensor until it is loosened.

Can you please tell me what the square flex circuit (with 2 square contacts) is for, which is surrounding the FP Sensor? Mine was damaged, when my back cover was cracked. I have replaced the back cover, and will be getting another FP sensor (as mine is inoperable), but that large square flex is also damaged. I have no idea what this is for? I thought it was connected to the NFC circuit, but the phone still charges wirelessly.

I think that is the NFC antenna, which is mainly used for contactless payment and ID systems. It’s not used for wireless charging, which is the coil on top of the battery. Depending on how it is damaged, your NFC function may still work—it may just have less range if the antenna’s damaged.

The link to the Google tool to get the Pixel 3XL phone to recognize the new fingerprint sensor only works for Pixel 6 and newer. Perhaps the tool accessed by the link previously supported the Pixel 3XL, but no longer does. Either a correct reactivation tool for the Pixel 3 should be provided or this guide should be taken down. As it stands, it seems useless to replace the sensor unless a way is provided to get the phone to recognize the new one. If there is an alternate way to activate the new sensor, the method should be provided in the guide.
