Samsung Galaxy S10e Fingerprint Sensor Replacement

Opening your phone will breach its waterproof seals; have replacement adhesive prepared for reassembly.

Ensure the phone is completely powered off before starting this repair.

• Prepare an iOpener and apply heat to the right edge of the back cover for about two minutes.
• Reheat and reapply the iOpener as needed, following its instructions to avoid overheating.

Alternatively, use a hair dryer, heat gun, or hot plate but exercise caution: excessive heat can damage the OLED display or internal battery.

Locate the adhesive layout as shown in the first image, where the back cover's inside has been exposed.

• Slice through the highlighted areas on the outside of the phone to cut through the adhesive.
• The thinnest layer of adhesive is located on the right side, just below the Bixby button.

Apply a suction cup to the back cover, just below the Bixby button where the adhesive is thinnest.

• Avoid placing the suction cup on the curved edge of the glass.
• If the phone's back cover is cracked, try using strong tape or superglue to secure the suction cup in place and allow it to cure.

Excessive force or improper tools may damage the phone's rear glass.

• Prop up the heated phone on a support of at least 0.5 inches (13 mm) thickness for easier access.
• Lift the back cover's right edge with a suction cup, creating a small gap between it and the frame.
• Use gentle force; if needed, apply more heat and try again due to rapidly cooling adhesive.
• Follow iOpener heating instructions to avoid overheating and bursting the gel pack.
• Pry open the phone with a non-metallic opening tool at the created gap.

• Insert the opening tool into the phone's right edge.
• Run the tool along the edge to cut through the adhesive holding the back cover in place.

Insert a opening pick next to the opening tool, leaving it in place to prevent re-adhesion of the separated glue.

Apply a iOpener to the top edge of the phone and heat for 2 minutes.

Insert an opening pick near the top right corner of the phone and slide it around the corner and across the top edge.

Be cautious as the glued area is larger here, requiring a deeper insertion to separate it effectively.

Leave the opening pick in place to prevent re-adhesion of the adhesive.

Apply iOpener to left edge for 2 minutes.

• Place an opening pick near the top-left corner and gently push it towards the left edge.
• Leave the opening pick in place along the left edge to keep the adhesive from reforming.

Apply a iOpener preheated according to manufacturer's instructions to the bottom edge of the device for 2 minutes.

Insert opening pick at a bottom corner of the phone.

• Slide along the bottom edge to separate adhesive.
• Be cautious, as the glued area is larger here and requires more force.

Use a opening pick to carefully pry up the back cover.

Stop prying if you encounter resistance; use the opening pick to cut any remaining adhesive instead.

• Continue removing the back cover once all adhesives are released.

Turn on your phone and test the repair before applying new adhesive.

• Reinstall the back cover, or just clean away large chunks of old adhesive if desired.
• If replacing adhesive, apply it to the back cover and secure with pressure, though note that waterproofing will be compromised.

Remove the 8 x 3.9 mm Phillips screws that secure the upper midframe.

Insert an opening pick at the bottom right corner of the upper midframe.

• Gently slide the pick along the edge, separating the adhesive from the lower midframe.

Insert the spudger into the small cutout near the Bixby button, right edge of the upper midframe.

• Apply gentle pressure with the spudger to pry the midframe up from the phone chassis.

Locate the plastic midframe section and lift the midframe out of the phone.

• When reinstalling, insert the top edge of the assembly into the phone's frame first.
• Gently press down on the rest of the assembly to snap it securely into place.

Use the flat end of a spudger to carefully lift the battery connector straight out of its socket.

Remove the loudspeaker screws with a Phillips driver.

• The speaker is secured by seven 3.9 mm Phillips screws.

Insert the point of a spudger into the notch on the right edge of the loudspeaker.

• Pry up with the spudger to loosen the loudspeaker.

• Lift the loudspeaker out of its mounting.
• Remove the loudspeaker.

To reassemble:

• Press the loudspeaker edges together until it snaps into place.

Never press down in the middle of the connector — risk of pin bending and permanent damage.

• Use a spudger to pry up the screen connector from its motherboard socket.
• To re-attach, align carefully and press one side until it clicks into place. Repeat on the other side.

Insert the spudger's point under the fingerprint sensor connector and gently pry it loose, then lift it away from the motherboard socket.

Remove the fingerprint sensor bracket's 2 x 4 mm Phillips screws using a Phillips driver.

Use caution when applying heat to avoid damage.

• Place a iOpener on the fingerprint sensor bracket and apply heat for one minute.

Strong adhesive holds the fingerprint sensor bracket in place.

• Use tweezers to carefully pry up the fingerprint sensor bracket.
• If it won't move, apply more heat and try again.
• Once loose, remove the fingerprint sensor bracket.

Loosen the fingerprint sensor cable from the adhesive gasket using a pair of tweezers.

Flip the phone over and position the display for access.

• Apply a heated iOpener to the right edge of the screen for two minutes.

Be cautious not to overheat, as internal damage can occur.

Note the following seams:

• Display seam: Prying along this seam will separate the display. It is located above the thin plastic bezel.
• Frame seam: Do not pry along this seam, as damage to the plastic bezel can occur. It is situated below the thin plastic bezel.

Be cautious not to scratch the display.

• Apply a suction cup to the heated edge of the display.
• Pull up on the suction cup with strong, steady force until a gap forms.
• Insert the point of an opening pick into the seam above the plastic bezel.

If device is old or stubborn, reapply heat and try again.

Insert an opening pick into the right edge and gently slide it along to cut through the adhesive.

Do not remove the opening pick yet, as this can cause the adhesive to reseal.

Place a heated iOpener on the bottom edge of the display and let it stay for 60 seconds.

Insert an opening pick under the device and slide it along the bottom edge to cut the adhesive.

Make sure the pick remains in one corner to prevent the adhesive from re-sealing.

Repeat the heat treatment and slicing process for all unprocessed display sides.

Exposure to air will damage the OLED panel.

• Lift up and remove the display glass.

Use a iOpener to heat the OLED panel for 1 minute.

• The goal is to soften the panel adhesive.

Lift the display panel from the right edge.

• Pry it away from the frame.

Insert the display panel connector into the frame.

• If it's stuck, consider cutting the display panel cable for easy removal.

Remove the display panel.

• If using a custom-cut adhesive, refer to the removal and replacement instructions.
• If reattaching with Tesa tape, consult the relevant guide for proper application.

Use the flat end of a spudger to gently pry up the fingerprint cable cover from the frame.

• Continue prying until the cover is fully removed.

Use the pointed end of a spudger to carefully pry out the fingerprint sensor cable from its frame cutout.

Remove the power button support bracket using a pair of tweezers.

• During reassembly, orient the bracket with the indents facing away from the button.
• The center tab should face upwards.

Remove the fingerprint sensor from its recess.
