Introdução

Follow this guide to remove and replace the fingerprint sensor on a Motorola Edge. The fingerprint sensor resides beneath the display panel.

There is a significant chance that you may break the unreinforced and fragile display panel during this procedure. Be sure to apply plenty of heat and be extremely careful during the prying stage.

You’ll need to loosen the battery in order to remove the display panel.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

    • Find the SIM tray located at the top of the phone.

  2. Motorola Edge Fingerprint Sensor Replacement, Eject the SIM tray: passo 2, imagem 1 %32 Motorola Edge Fingerprint Sensor Replacement, Eject the SIM tray: passo 2, imagem 2 %32
    • Insert a SIM eject tool or SIM eject bit into the small hole in the SIM card tray.

    • If the tool you're using doesn't fit, don't force it. Forcing a tool may cause it to get stuck or break inside the ejection port.

    • Press to eject the tray.

  4. Motorola Edge Fingerprint Sensor Replacement, Heat the bottom edge: passo 4, imagem 1 %32
    • Completely power off your phone before you begin.

    • Heat an iOpener, then apply it along the bottom edge of the back cover for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone because the display and internal battery are both susceptible to heat damage.

  5. Motorola Edge Fingerprint Sensor Replacement, Separate the bottom adhesive: passo 5, imagem 1 %32 Motorola Edge Fingerprint Sensor Replacement, Separate the bottom adhesive: passo 5, imagem 2 %32 Motorola Edge Fingerprint Sensor Replacement, Separate the bottom adhesive: passo 5, imagem 3 %32
    • Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.

    • Pull up on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Depending on the age of your phone, this may be difficult. If you're having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.
