How to fix Galaxy Note10+ fingerprint scanner not working | fingerprint scanner not detecting finger

If your Galaxy Note10+ fingerprint scanner is not working, there’s a number of possible factors that might cause it. Follow this guide to fix the issue.

Galaxy Note10+ fingerprint scanner not working fix #1: Clean the screen | remove screen protector

If your Galaxy Note10+ fingerprint scanner appears to be not working, the first troubleshooting step that you must do is ensure that the screen is clean. Technically, presence of dust,smudge, or dirt on the screen would have little effect on your device’s fingerprint scanner as it uses sound in scanning a 3D image of a finger. However, real world tests show otherwise. Be sure that you wipe the screen with a clean, soft cloth before unlocking your device with your finger. 

If you’re using a screen protector, try to remove it and see if fingerprint scanner starts working again. Poorly installed or low quality screen protector may degrade the scanner’s capability. If nothing works, continue with the troubleshooting steps below.

Galaxy Note10+ fingerprint scanner not working fix #2: Reposition your finger

The fingerprint scanner is located a little lower below the middle portion of the screen. If your finger is way below that portion, the scanner may not be able to make a full scan of your finger.

Some bugs are only fixable with updates. Be sure to keep all apps and software updated. To keep apps updated, follow these steps:

You can also manually check for updates by going under Settings > Software update.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. The Recovery screen menu will now appear. When you see this, release the buttons.
  5. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  6. Press the Power button to select ‘Wipe cache partition.’
  7. Use Volume Down to highlight Yes.
  8. Press the Power button to confirm the action to clear the cache.

Galaxy Note10+ fingerprint scanner not working fix #7: Reset app preferences

Some apps need default apps and services in order to work. If these necessary apps or services are disabled for some reason, an app that requires them to work may stop running altogether, or stop working properly. To ensure that default apps and services are enabled, follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Galaxy Note10+ and check for the problem.

Galaxy Note10+ fingerprint scanner not working fix #8: Observe on Safe Mode

Another possible reason for the problem may be a bad third party app. To check, try to restart the device to safe mode. In this mode, all third party apps are suspended so if Galaxy Note10+ fingerprint scanner works normally, you can assume that the issue is caused by a third party app. To check if that’s the case, restart the phone to safe mode. Here’s how to do that:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the problem is non-existent on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy Note10+ is still problematic, repeat steps 1-4.
