H2: How to Fix Galaxy Note 20/Note 20 Ultra Fingerprint Not Working Issue

To fix Galaxy Note 20/Note 20 Ultra fingerprint not working issue, make sure the ultrasonic fingerprint sensor captures your fingerprint data correctly. Thus, use only a dry finger and double-check the fingerprint sensor for dirt.  

The Samsung Galaxy Note 20 series uses the ultrasonic method in fingerprint ID, a more robust method than the optical method used by older models. That means fixing fingerprint issues here should be a lot easier to handle. 

With that said, it’s best to be efficient. Follow the instructions below and learn how to easily overcome the Galaxy Note 20/Note 20 Ultra Fingerprint not working issue.

If you can already see smudges on your phone’s screen, then you may already have an idea of what causes the problem. Smudges can affect how the screen sensors perform a scan to authenticate the fingerprint, so cleaning it is wise. 

Follow the steps below to clean your screen effectively. 

  • Get a lint-free cloth that is soft and dry.
  • Dampen the prepared cloth using an alcohol solution.
  • Gently wipe the screen to get rid of any dust or smudges.

Now that you already have a clean screen, it is also essential to clean your finger. After ensuring you have a clean finger and fingerprint sensor, try unlocking your phone using your fingerprint.

2. Remove the screen protector

Screen protectors that are of low quality, too thick, or too dark may result in fingerprint issues. This is especially when you’ve noticed that the problem started after putting the screen protector on your phone. 

Remove it, then do a test run on your fingerprint scanner. If it’s still not working, proceed to the next step. 

3. Increase the screen sensitivity

  • Go to Settings.
  • Click Display. 
  • Find the Touch Sensitivity option
  • Tap the button beside Touch Sensitivity to Toggle On.

4. Use new fingerprints.

There’s a chance that your old fingerprints may not match the current fingerprint you have. This happens when your fingers just had scars or you’ve restored fingerprints from your old phone and then transferred them to your current one.

Thus, a way to go around this is to delete old fingerprints stored and put in new ones.

If you are already in this section and none of the steps before worked, performing a factory reset on your phone may solve this fingerprint issue. 

WARNING: Factory reset means all your data is erased as it puts your phone in the original state when it left the factory. So, it should be a last resort. 

A factory reset erases all your data from your phone. So to do it right, it’s highly recommended to have a backup of all essential documents and files on your device before doing this. 

This may look like a drastic solution, but this procedure is very effective, especially when dealing with software issues, just as fingerprint scanner concerns. You’re all set for this process if you’re done backing up essential data from your device.

Follow the procedures below to factory reset your Samsung Galaxy Note 20 device:

  • Go to Settings.
  • Click General management.
  • Choose the Reset option.
  • Then tap the Factory data reset.
  • Scroll down until you see the Reset button, then click that.
  • To continue with the Factory reset, click Delete all.

This process will just take minutes to be finished. After this process, your phone will reboot, which is a cue for you to test your device’s fingerprint sensor.

Otherwise, it’s time to bring out the big guns. We mean consulting your nearest Samsung Service Center for a detailed inspection by their technician, as this may be more of a hardware problem than software-related.

FAQs About Galaxy Note 20/Note 20 Ultra Fingerprint 

What makes the Galaxy Note 20 series fingerprint feature cutting-edge technology?

Samsung Galaxy Note 20 series uses ultrasonic pulse captures instead of the optical method used by older phones. Ultrasonic has a higher recognition rate as it isn’t affected by brightness or lack of light; plus, it’s spoofing-proof as the user’s print is mapped in 3D. 

How fast is the fingerprint recognition rate of Galaxy Note 20/Note 20 Ultra?

Typically, fingerprint recognition should be just a matter of microseconds after putting your fingerprint in the screen’s scanner. However, if it’s already more than 1-2 seconds and your phone still does not respond, it may be an issue. 

Why does the fingerprint feature activate when accidentally touched?

This is probably because the always-on fingerprint feature was enabled. Accidental touching can activate the fingerprint scanner, so deactivating the always-on fingerprint feature is wise. 
Here’s how you can deactivate the always-on Fingerprint feature:

•Go to settings.
•Click Biometrics and security option.
•Tap Fingerprints.
•Toggle Off the button beside Fingerprint always on to deactivate it.

How can I report this fingerprint issue to Samsung?

You can notify Samsung using your phone’s Samsung Members app, where you can report concerns or ask questions to them. If an issue persists, notifying the manufacturer is always best. 
You need not worry about your privacy, as any problem and question you relay is sent and received by Samsung anonymously. Most importantly, your submitted case is only held during their team’s investigation.
