Introduction

This is a guide to replace the fingerprint sensor on the Moto G Power (2020). Follow these simple steps for a successful repair! If you encounter other issues, refer to our troubleshooting page.

Before you begin, download the Rescue and Smart Assistant app. This will allow you to back up your device and determine if your problem is software or hardware-related.

    • Position a suction cup securely on the back panel of the device.

    • Insert the opening pick into both sides of the phone and carefully slide it along to open the back panel of the device.

    • Do not fully remove the back panel; disconnect the fingerprint sensor first.

    I am finding it extremely difficult to find an insertion point between the casing and the screen. I've even brought a Stanley No. 199 Utility knife into play. Still, no separation. These instructions should include the use of a heat gun to soften the adhesive that holds the case and screen together. I may have to bring this to a cell phone repair shop.

    Light heat with a blowdryer/heatgun will help it flex more, but you can do it this way. It's definitely challenging as you have to pull on the suction cup close to the edge and you might only get like .5mm of gap.

    If you don't have a good spudger or thin piicks like in the picture, heat gun is absolutely necessary.

    One thing to note: be careful with a spudger or prying near the right side of the phone. A small wire runs from top to bottom of the phone about 5mm past the phone edge. You can see it in the pictures, it's a black wire that's very tiny. It's easy to see in Step 7 where it connects to the board above the right corner of the battery.

    I had a terrible time with the adhesive on the back cover, I lost most of the black film around the camera lens and some around the middle of the bottom edge. I put modest effort towards reinstalling the touch sensor into the back cover, but since I use an external case I did not go overboard. I did test the touch sensor before firmly seating the back cover into the remaining adhesive.

    • Apply gentle pressure to the fingerprint sensor with your finger to detach it from the back panel.

    • You may need to apply firm pressure to remove the circular sensor from the panel.

  3. JmuULJFCOcDaiIIC

    • Fully remove the back panel from the device.

  4. VkO3KWkVeZkYEV1U

    • Using a Torx T3 screwdriver, remove nine 2.2 mm screws.

    When I re-installed the back cover, I found that the left side around the camera lenses was the hardest part to get back into place, so I put the 4 left screws in first (lower left corner, then upper left corner, then left of the 3 lenses, then lower right of the top lens). I don't know what torque spec they use in the factory, but only 2 of the 9 screws came out easily so I put them back in with the "stop when you feel resistance" standard.

    • Use the spudger to gently lift the cover.

    • If needed, use the spudger's tip against a corner of the cover to help lift it.

    • Set the back cover aside.

    • DO NOT use excessive force when lifting up the back cover.

    As shown, the bottom left corner is a good place for the first lift of the cover, then the bottom right side which should release the bottom edge, then pivot the cover up toward the top, and it should lift off easily.

    • Carefully use the spudger to lift the sensor cable, disconnecting the fingerprint sensor from the motherboard.

    • WARNING: Handle the sensor cable with care; it can be easily damaged.

    • Carefully remove the fingerprint sensor from the device and set it aside.

    • Do not use excessive force when lifting the back cover or any other component.
