  1. Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: шаг 1, изображение 1 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: шаг 1, изображение 2 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Heat the edge of the back cover: шаг 1, изображение 3 из 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: шаг 2, изображение 1 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Create a gap under the back cover: шаг 2, изображение 2 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Create a gap under the back cover: шаг 2, изображение 3 из 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.

    Suction cup doesn’t work on severely cracked glass.

    Step 1 - 2 took me about 50 minutes. Back and forth with heat and trying with suction cup. I could get my finger nail in but not the pick. Took two people, but we finally got a pick in. 2 year old phone.

    Took about 15 minutes and three total attempts. On the third attempt, I also used a thinner, metal, pick to widen the gap just enough for the plastic pick to fit (Though be careful as you can easily break it with a metal pick). The phone is three years old.

    Could not get in with the pick or in from the side. Targeted the bottom of the phone with the iOpener and managed to gently create some space for the pick with the opener tool.

    I also struggled here for a while. I ended up working my way around the entire edge of the phone until I found one spot where I could pry up the back panel. I used a jimmy instead of the opening pics. I also used a hairdryer on lower heat instead of the iopener. 3 year old phone.

    Took 30 minutes + to get the back cover off. Used another suction cup to grip from the busted screen and the ifixit suction cup for the back. A thinner Acoustic guitar pick was required opposed to the standard Blues picks provided in the kit (har-har). Would HIGHLY suggest getting a pick into both the back and the front before removing the panels as it will give you more surfaces to pry from. Made that mistake...

    Over 2 hours of trying, I keep reheating the pouch and let it sit on the edge for sometimes up to 10 minutes since the directed 1 minute wasn't working. Physically cant get enough leverage on the back of the phone; picks are too thick to get under the crack, and the suction cup pops off before I can get enough force to see any gap open. Phone is 5 years old. I really need some help

    Hey Grant!
    I hear your pain—the adhesives on this phone are very strong. The initial gap is one of the hardest parts of the procedure. Here are some suggestions:
    * If you have a hair dryer, give that a shot. Heat the edge until it is slightly too hot to the touch.

    * These adhesives separate not with extreme force, but with constant steady force and time. Try heating the edge and pull on the suction cup with firm force for about a minute to let the adhesive separate.

    * If you have an opening tool, you can try this procedure to get the initial 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.

    • 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: шаг 6, изображение 1 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the remaining edges: шаг 6, изображение 2 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the remaining edges: шаг 6, изображение 3 из 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.

    The back cover is Glass!!!!. DO NOT PRY HARD, IT WILL BREAK!!!!!!!

    You must go slowly and let the heat do the work, if you force the cover off, it will shatter.

  7. Google Pixel 3 XL Fingerprint Sensor Replacement, Slice through the leftover adhesive: шаг 7, изображение 1 из 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: шаг 8, изображение 1 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Swing open the back cover: шаг 8, изображение 2 из 3 Google Pixel 3 XL Fingerprint Sensor Replacement, Swing open the back cover: шаг 8, изображение 3 из 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.

    Reassembly is way harder. The adhesive guide is generic and not super helpful, so don't be surprised if things went smoothly until you get to this step and then everything starts sticking to things its not supposed to.

    This is great but how you address that fact that the phone is tied to a particular fingerprint sensor and after replacing, the new sensor is not recognized by the original phone?

    Dave - Ответить

    Hi Dave!

    There's a software calibration tool that you can use to calibrate your new fingerprint sensor. I've updated this step to include a link to the tool.

    Arthur Shi -

    I have a pixel 3 xl and I can't get the tool to work. I finally got the driver's installed after several hours and it says it's for pixel 6 and up basically. So I tried the other option and it's basically saying to do a factory reset? Did I mess something up on the install or what am I doing wrong here? Thanks

    Cody L Paulsell - Ответить

    Uhhh

    So, apparently the connector on the motherboard for the fingerprint sensor is just ridiculously fragile, because after plugging and screwing everything in (pretty much reassembled except for the adhesive), I closed up the phone and powered it on to test if everything was working, and when I opened it back up and let the top hang off to the side, it just snapped off. I didn't even have it tensioned that much, it was just hanging off to the side and snapped. So now I've traded a non-functional camera with a non-functional and irreparable (unless I get a new motherboard) fingerprint sensor.

    The guide really ought to emphasize how delicate that connector really is. I have a google drive link here to a photo of the remnants of my poor fingerprint sensor connector :( link

    Wasted a ton of time and effort (and money) trying to use this guide to repair my Pixel 3XL. Then I get to the software calibration tool and find:

    Unsupported device

    This is not a compatible device. Only Pixel 6, 6 Pro, 6a, 7, 7 Pro, 7a devices can install this software.

    I cannot say how frustrating it is when a guide and website that tried to be so helpful ends up like this. Failure due to referencing tools not on the site and not suitable for the job.

  9. Google Pixel 3 XL Fingerprint Sensor Replacement, Remove the fingerprint sensor tape: шаг 9, изображение 1 из 1
    • User tweezers to carefully peel up the yellow tape over the fingerprint sensor connector.

    This step is utterly unnecessary. It achieves nothing, and the tape is there for a reason (I'm not sure why, maybe to prevent short circuits). I didn't remove this tape while disassembling and it didn't change anything.

    Krzeszny - Ответить

    The Kapton tape should adhere to both the cable and the connector. It helps prevent the cable from slipping out of the ZIF connector. You're right in that you don't have to completely remove the tape—I've adjusted the step to reflect this.

    Arthur Shi -

    I just finished this guide, thank you. It would be nice to have a "before ribbon removed" reference picture that's also without the Kapton tape in place if possible. I was no longer certain how far back into the ZIF connector I had to place the ribbon cable as I simply forgot what it looked like before removing it. Basically, it "felt" like it was out too far, but since I had no reference I couldn't compare. Step 10 has good close up pics, but the ribbon cable is already out a bit so a bad reference.

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.

ArcadeDude44 - Ответить

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.

Arthur Shi -

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.
