How to fix Samsung Galaxy Note 5 that doesn’t recognize fingerprint [Troubleshooting Guide]

One of the selling points of the #Samsung #Galaxy Note 5 (#Note5) is its fingerprint scanner. Being one of the few devices that allow users to unlock the lockscreen using biometrics, the Note 5 is actually considered one of the most advanced smartphones but did it live up to the expectations of the users?

Samsung did a great job in making its biometric technology stable and while there were many Note 5 owners who were complaining about fingerprint-related issues, they were just a small percentage of owners who are actually enjoying the phone. But the thing is we are obliged to help our readers fix their issues, hence this post.

So, in this article, I will tackle the problem involving the Note 5 whose fingerprint scanner fails or can no longer recognize the prints of the user. This has been one of the most reported problems since the release and it’s still haunting some of the users. Before we go any further, I want to cite one of the actual messages sent by one of our readers who is currently bugged by this problem.

Hey guys. I just want to ask a little help from you regarding my phone, a Galaxy Note 5. I really can’t remember when this problem started but it just won’t recognize all my fingerprints anymore. The problem started sporadically and then it became frequent and now it’s just stuck. Whenever I swipe my print, it won’t recognize it and I can go doing the same thing over and over all day without going nowhere. I’m not sure what to do now so if you guys know how to fix this, help me please. Thanks.

Could  the user get into his/her phone even if the fingerprint scanner fails? Aside from the fingerprints, there is also a backup PIN or password you could use. Did they fail, too?

What to do if you can get into your phone even with the fingerprint scanner failing? It’s a no-brainer actually; disable fingerprint scanning. Or, you can try to delete stored prints and replace them with a new set that works. By doing this, you can also probe further if there really is a problem with the biometric scanner and then you can decide whether to use it or not.

What if the scanner still fails to recognize new fingerprints?

Then you might be looking at a possible hardware issue involving the biometric scanner itself or it could be a firmware problem caused by some unseen elements. Since we can’t do anything about the hardware, it’s logical to just rule out the possibility of the latter and see if the issue gets fixed.

The fingerprint scanner is a feature embedded in the firmware and no third-party apps can cause it to crash. That being said, if it fails, then it’s wise to go after the firmware the directly. In other words, you have to reset your phone but before that, make sure you backup your data and files as they’ll be deleted.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

After the reset, try to register new fingerprints and test your device. If it still fails, then it’s best that you send the phone for repair or bring it to the store and have a technician take a look at it.

But what if the user couldn’t get into his/her phone due to failing fingerprint scanner and that the password or PIN doesn’t work as well?

It’s still imperative to troubleshoot your device to see if you can fix the problem. For sure, it didn’t occur without any cause and based on reports from owners who encountered this issue, it’s the firmware update that often lead to this situation. In this case, it’s possible that some of the caches got corrupted and affected some of the native functions of the phone. Therefore, the first thing you have to do is to delete the system cache.

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

This troubleshooting procedure isn’t just based on theory that maybe some caches got corrupted but it is also from owners who reportedly been able to get into their devices after doing it. Of course, there’s no guarantee but it’s worth doing it. After wiping the cache partition, try to see if your Note 5 can recognize your prints, if still not, then you have no other choice but to reset it just to regain access. You will lose your files and data along the process but it’s the only way to make your device useful again.

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

This of course will bring the phone back to its default settings but continue observing your phone for the same signs. It’s better that you refrain from using Fingerprints until you’re sure that it’s working properly.
