Fix: ‘In-Display Fingerprint Scanner Not Working’ issue

Fix your in-display fingerprint scanner quickly and easily with these troubleshooting tips

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.
  • Screen protector: If you have a screen protector applied to your phone, it might be interfering with the fingerprint scanner. Try removing the screen protector and see if that fixes the problem.
  • Wet or oily fingers: If your fingers are wet or oily, the fingerprint scanner will not be able to read your fingerprint properly. Make sure your fingers are dry and clean before trying to use the fingerprint scanner.

Factory Reset Your Phone

If the things above don’t help, you may need to do a factory reset. Before you do a factory reset, you should make sure you have a copy of all your data. That can be done by going to Settings > System > Reset options > Erase all data (factory reset).

Clean the Fingerprint Scanner

If your fingerprint scanner is giving you trouble, the first thing you should do is clean it. Over time, dust, sweat, or even fingerprints could build up on the scanner and make it less useful.
