Step-by-step

1. 1

   Power off the phone

   1 min

   Press and hold the Power and Volume Down buttons, then tap Power Off on the screen. Ensure the device is fully shut down before proceeding.

2. 2

   Heat the back glass

   3 min

   Apply heat to the edges of the back cover for 2 to 3 minutes using a heat gun set to low. This softens the factory perimeter adhesive.

3. 3

   Apply suction cup

   2 min

   Attach a suction cup to the lower third of the rear glass near the bottom edge. Pull up gently to create a small gap between the glass and the frame.

4. 4

   Insert opening pick

   2 min

   Insert a plastic opening pick into the gap created by the suction cup. Slide it slightly along the bottom edge to sever the adhesive.

5. 5

   Slice remaining adhesive

   4 min

   Slide the opening pick around the perimeter of the back panel. Reapply heat if the pick encounters strong resistance.

6. 6

   Lift off the back cover

   1 min

   Gently lift the back glass panel away from the frame. Set the rear glass aside on a clean work surface.

7. 7

   Unscrew the midframe

   4 min

   Remove the 15 Phillips #000 screws securing the wireless charging assembly and upper midframe shield.

8. 8

   Disconnect the battery

   1 min

   Use the flat end of a plastic spudger to pry the battery connector straight up from the motherboard socket.

9. 9

   Remove the midframe shield

   3 min

   Peel up the wireless charging pad and unclip the plastic midframe assembly from the top and sides of the frame.

10. 10

    Disconnect the fingerprint sensor flex

    2 min

    Locate the fingerprint sensor ribbon connector near the lower portion of the motherboard. Use a spudger to gently pop the connector off its socket.

11. 11

    Remove the motherboard

    4 min

    Disconnect the display cable and remaining flex cables from the board. Lift the motherboard assembly carefully out of the chassis.

12. 12

    Heat the fingerprint sensor area

    2 min

    Apply light heat to the lower front region of the display panel for 1 minute to loosen the ultrasonic sensor adhesive inside.

13. 13

    Pry up the damaged fingerprint sensor

    3 min

    Insert thin tweezers beneath the fingerprint sensor module mounted behind the screen frame. Carefully lift and detach the sensor from the back of the OLED panel.

14. 14

    Install the new fingerprint sensor

    2 min

    Align the replacement sensor module precisely in the recessed bay behind the display. Press firmly for 10 seconds to secure the adhesive.

15. 15

    Reinstall the motherboard

    4 min

    Lower the motherboard back into the frame slot, making sure no ribbon cables get trapped underneath. Snap all display and sensor flex cables back into place.

16. 16

    Reconnect the battery and midframe

    4 min

    Press the battery connector into its motherboard socket. Reposition the wireless charging coil and midframe, then tighten the 15 Phillips screws.

17. 17

    Seal the back glass

    3 min

    Apply pre-cut replacement adhesive to the frame border. Align the back cover and press firmly along all edges to reseal the phone.
