Introduzione

Follow this guide to remove and replace a defective fingerprint scanner/home button for the OnePlus 5. The fingerprint scanner is layered underneath the loudspeaker module and the daughterboard. The hardest part of the guide is getting the frame clips of the back cover free to access the internals of the phone.

Some guide images will show the battery already removed from the phone. You do not need to remove the battery for this procedure.

  1. Insert a SIM card eject tool, bit, or a straightened paperclip into the small hole below the SIM card tray, located near the rear cameras on the edge of the phone. Press firmly to eject the tray. When reinserting the SIM card tray, ensure that it is in the proper orientation as shown.

    • The following four steps show how to pry the rear case from the plastic frame. Read through the steps first before attempting the procedure.

    • There are two different seams between the body and the screen of the phone:

    • Display panel seam: This seam is part of the display assembly. Do not pry at this seam, or you will separate and damage the display panel.

    • Frame seam: This is where the plastic frame meets the back cover. Only pry at this seam.

    • There are twelve clips that hold the frame against the rear case. Be aware of their location as you pry the back cover off in the following steps.

  4. As you work, try not to accidentally power on the phone. If you do, turn the phone off before resuming disassembly. Place a suction cup near the bottom edge of the display.
    • As you work, try not to accidentally power on the phone. If you do, turn the phone off before resuming disassembly.

    • Place a suction cup near the bottom edge of the display.

    • Pull on the suction cup with strong steady force.

    • Press the edge of an opening tool straight into the frame seam near the suction cup until the edge wedges between the plastic frame and the back cover's lip.

    • Due to tight tolerances, this will take substantial force. Using a new opening tool with an unmarred edge will help with this step.

  5. Once the opening tool's edge is wedged in position, carefully slide the tool along the bottom edge of the phone. Carefully guide the opening tool around the left corner of the phone while keeping the tool's edge within the seam.

    • The frame is still connected to the back cover by a long flex cable. Do not remove the back cover.

    • During reassembly, pause here to test your phone's functionality before securing the back cover.

    • To reinstall the back cover:

    • Align the top edge of the frame to the back cover and ensure that the top clips slip into place.

    • Squeeze along the long edges of the phone to snap the remaining clips into place.

  9. With all the clips released, flip the phone over so that the display is face-down. Swing the back cover around and rest it on top of the exposed frame. Be careful not to stress the flex cable connecting the back cover and the frame.
