What to do with Vanished Fingerprint on your Google Pixel after Screen Replacement?

A common problem that occurs with Google Pixel smartphones is the failure of the fingerprint scanner after replacing the screen. In this blog, we share effective solutions to address this problem so that your customer can continue to use their phone effortlessly.

Start by Checking the Flex Cable

Make sure the fingerprint scanner flex cable is correctly connected to the motherboard and that it is not damaged. This is important to check because it could be causing the problem. If this is not the case, you have an idea where the possible problem could lie. If the cable does connect properly to the motherboard, it is likely that the fingerprint scanner needs to be recalibrated. Below are the steps to do this:

The Step-by-Step Calibration of the Fingerprint Scanner:

(Note: These steps only apply to the Google Pixel 6 and newer models.)

Step 1: Turn off the cell phone.

Step 2: Press the power button and volume down button for three seconds to enter the quick boot mode.

Step 3: Connect the phone to the computer.

Step 4: Go to the calibration software and click on "Connect Device". Select the appropriate device.
