Aside from a password, PIN, or pattern, one of the best ways to secure your Android phone is through a fingerprint. Yes! No one can copy your fingerprint right off the bat, which makes it a safer security measure. It’s the quickest way to unlock your phone, too, making the Android experience much more convenient.
But despite how convenient such a security feature is, there are times when you’re unable to use it at all. You may even get locked out of your lock screen. And that happens when the fingerprint sensor is not working.
If you’re in a similar situation, you may be asking yourself: Why is my fingerprint not working? Well, you’re just on the right page. Below, we are going to answer that and give you tips on how to fix the issue. We will also include measures to unlock your phone should the issue doesn’t get solved. Read on!
FYI: Why Is My Fingerprint Sensor Not Working
There are many culprits as to why your Android phone’s fingerprint scanner stops working. And it’s important that you get acquainted with them before you start fixing and troubleshooting. That way, you will know whether you can avoid such an issue.
Please note that we are going to list the known causes and add quick fixes for each of them.
Your Fingerprint Is Faded or Deformed
If you’re exposed to work or hobbies that involve using your finger, there’s a high chance of injury or scarring in the area. Like if you’re always playing the guitar, your fingerprint may fade for a while. Or if you got into an accident that burned your finger, your phone won’t be able to recognize it.
Register your other fingerprints. Most Android phones these days allow up to 5 fingerprints. You can do this if you can still access your phone via backup pattern/PIN/password.
Your Finger or Fingerprint Sensor Is Wet or Dirty
This is the most common cause of why you can’t unlock your phone using your fingerprint. Most Android phones today use optical fingerprint scanners, which take a picture of your fingerprint for verification. Liquid or dirt can make things blurry for the scanner. This also goes the same way for your phone’s fingerprint sensor. This is pretty common for users with sweaty hands.
Before you use the scanner, wipe clean your finger/s or the screen first.
There’s A Software Bug
Sometimes, your phone encounters bugs due to an issue when you last updated it or the OS version that it’s currently running on is buggy.
To fix this, you may simply update your phone to the latest version to get the bugs fixed. Just open the phone’s Settings and scroll down to Software Update. Oftentimes, you can find it in About Phone. The location varies slightly depending on the brand.
But if your phone doesn’t have any available updates, you may wait or have a professional software technician reprogram your phone.
The Fingerprint Hardware is Damaged
Rarely, the fingerprint hardware may get damaged as well. You may have accidentally soaked the phone underwater or it’s just a factory defect.
Either way, the only option you can do is take your phone to a professional technician to have the hardware component repaired or replaced or claim your warranty if the device is still within the period.
If none of the causes above is responsible for the fingerprint sensor not working issue, there are advanced solutions you can try.
