This article will show you how to fix ‘In-Display Fingerprint Scanner Not Working’ issue. There have been fingerprint scanners available for use on mobile devices for some time now. They started out as capacitive scanners on the back of a phone but have since evolved into ultrasonic ones that are built into the display. It is safe and convenient to use your fingerprint as the unlocking method for your phone. Because of how accustomed we are to it, having a fingerprint sensor that isn’t functioning properly can be very frustrating.

If you use an Android phone that has a fingerprint scanner regardless of whether it’s rear-mounted, side-mounted, or in-display – and it’s not working, there are a few things you can try to fix the issue. These solutions can be found in the following paragraphs. The following is a list of potential solutions to the problem of your phone lacking the necessary fingerprint hardware.

Why In-Display Fingerprint Scanner Not Working

  • Dirt and grime: Over time, dirt and grime can accumulate on the surface of your screen, blocking the fingerprint scanner from properly reading your fingerprint. To fix this, try cleaning your screen with a microfiber cloth.
