Google Pixel 2 Fingerprint Sensor Replacement

Tape the cracked display glass to prevent further breakage and bodily harm.

Taping also creates a smooth surface for the suction cup to bond to.

• Apply a suction cup near the volume button edge, avoiding the curved part of the glass.
• The suction cup won't seal properly on the curved portion of the glass.

Apply firm, constant pressure with the suction cup and insert an opening pick between the front panel and rear case.

• Do not insert the pick deeper than 1.5 mm to avoid damaging the OLED panel.
• It may take significant force and patience; if needed, rock the suction cup and screen or apply heat with an iOpener, heat gun, or hair dryer.

The display panel is fragile. When reusing your display, be careful not to insert tools too far under the glass.

Excessive force may cause permanent damage to the phone's display.

• Insert the pick no deeper than 9 mm into the bottom edge of the phone.
• Avoid contacting the OLED panel's folded portion with the pick to prevent display damage.
• Maintain shallow cuts when prying in the upper left corner, avoiding the front-facing camera.
• Do not insert an opening tool more than 1.5 mm into the sides or 9 mm into the top/bottom edges.

Use the flat part of the opening pick, not a corner, for cutting.

• Slide the opening pick along the right edge to separate the display adhesive.

Be careful with the side bezels — they are only 1.5 mm deep.

Insert the opening pick into the upper-right corner and slide it along the top edge.

• Bypass the mesh covering the earpiece speaker by gently navigating the pick around it.

• Do not damage or remove this component if a replacement is not available.

Slide the pick from the upper-left corner to the lower-left edge of the phone.

Be cautious when inserting the opening pick near the OLED corners.

• Slide the pick around the bottom-left corner and along the bottom of the phone, maintaining a slight angle away from the screen.
• Avoid inserting the pick more than 9 mm to prevent damaging the OLED panel.

Reinsert the pick at the top edge of the phone and gently pry up the display.

• If the display doesn't readily lift, use extra prying to separate the last of the adhesive.
• The adhesive near the upper speaker is thicker than other areas.
• Do not fully separate the display yet; a fragile ribbon cable still connects it to the phone's motherboard.

Position the display on top of the rear case as illustrated.

• Remove the two 4.0 mm T5 Torx screws securing the display cable bracket.
• Keep track of each screw and ensure it is replaced in its original position.

Disconnect the display cable bracket.

Use the point of a spudger to gently lift the display cable connector out of its socket on the motherboard.

Avoid touching the motherboard components around the socket, as they are fragile.

• To reattach, carefully align and press down on one side until it clicks into place. Repeat on the other side. Do not press in the middle.
• Be cautious of pin damage if the connector is misaligned.

If any screen area doesn't respond after repair, re-seat this connector and ensure proper alignment and cleanliness.

During reassembly, replace the adhesive around the display edges before proceeding further.

Softening the adhesive may damage the proximity sensor.

• Apply a iOpener to the proximity sensor on the top edge of the midframe.
• Heat for two minutes to soften its adhesive.

Locate the proximity sensor cable nearest to the front-facing camera.

• Insert the point of a spudger under the cable, starting from the side closest to the front-facing camera.
• Lift the edge of the sensor cable gently until it is perpendicular to the midframe.

Peel back the small piece of tape covering the screw below the earpiece speaker.

• Tape removal: Peel back any other tape covering screws as well.
• Remove the following screws:
• Nine 3.7 mm Phillips screws
• Torx screw: One 4 mm T5 Torx

• Keep track of each screw and ensure it is reinstalled exactly where it was removed from.

Locate the notch on the midframe near the hold button.

• opening tool into the notch.

Lift the midframe starting from the bottom edge.

• Continue lifting until the midframe is at a 45° angle with the phone.
• Lift the midframe straight up and away from the phone, carefully guiding the proximity sensor through its small slot in the midframe.

Disconnect the battery connector using the flat end of a spudger.

Disconnect the charging assembly connector using the flat end of a spudger.

Fill a plastic dropper or syringe with high concentration isopropyl alcohol.

• Apply a few drops of alcohol under each corner of the battery.
• Wait for one minute to allow the adhesive to weaken.

Alternatively, use a heated iOpener on the back of the phone over the battery for at least two minutes, reheating and reapplying as needed until the adhesive is sufficiently weakened.

Hold the charging assembly cable out of the way.

• Insert an opening pick along the bottom edge of the battery.
• Apply steady, even pressure to slowly lever the battery up and out of the phone.

Only pry from the center of the battery to avoid damaging delicate ribbon cables beneath either side of the battery.

Do not use excessive force or metal tools, as this may deform the soft-shell lithium-ion battery and lead to dangerous chemical leaks, fires, or explosions.

• If having trouble, apply more alcohol under the battery and try again.

Do not reuse a removed battery — risk of electrical shock.

• Remove and discard the old battery.
• Install a new battery:
• Scrape away adhesive using a spudger, then clean with isopropyl alcohol and lint-free cloth.
• Secure the battery with pre-cut adhesive or double-sided tape, avoiding cables under battery.
• Press new battery firmly into place for 20-30 seconds.

Disconnect the charging assembly connector from the motherboard using the flat end of a spudger.

Insert a SIM eject tool or paperclip into the small hole on the left side of the phone.

Continue pushing gently until the SIM card tray pops out.

• Remove the SIM card tray.

Remove the two 2.5 mm PH00 screws.

• Locate and remove the bottom edge connectors.

• Pry up the motherboard using a plastic opening tool.
• Remove the motherboard.

• Flip the motherboard over.
• Disconnect the fingerprint sensor cable.
• The motherboard is now completely detached from the phone.

Flip the device over with the display side facing downwards.

• Push the fingerprint sensor towards the interior using your hand.

Flip the device over with the display side facing up.

• Remove the fingerprint sensor.
