Introduction

Follow this guide to remove and replace the front-facing camera for the Moto X4. In order to access the camera, you must remove the motherboard.

  1. Motorola Moto X4 Front-facing Camera Replacement, Heat the screen: step 1, image 1 of 2 Motorola Moto X4 Front-facing Camera Replacement, Heat the screen: step 1, image 2 of 2
    • Before you begin, turn off your phone.

    • Heat an iOpener and apply it to the left edge of the phone for two minutes.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • 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.

    • As you wait, take note of the the following areas:

    • Display cable—be careful not to slice too deeply near the edge here, or you may damage the display cable.

    • Fingerprint sensor cable—be careful not to slice too deeply near the edge here, or you may damage the fingerprint sensor cable.

    • Apply a suction cup to the screen, as close to the heated edge as possible.

    • Pull on the suction cup with strong, steady force to create a gap in the seam.

    • Insert the point of an opening pick into the 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.
