The fingerprint scanner on the Galaxy S9 isn’t functioning — Here’s how to get things fixed.
Method 1: In Settings, change the Secured Lock Time.
Most phones do not have a hardware problem, contrary to popular belief, and most consumers want to replace their phones as soon as possible. According to a user remark on the Samsung support site, you can fix it by adjusting the secured lock duration in the settings menu.
- On your Galaxy S9 phone, tap to access the Settings menu.
- To discover the lock screen and security, scroll down.
- Please locate the secure lock settings page and open it.
- Secured Lock Time may be accessed by tapping on it.
- When you get to this point, you may select between Instantly with the Power Key and When the Screen Times Out.
When you press the power button to turn off your phone’s display, you may think it’s automatically locked. There is, however, a time wait before it is locked. Depending on personal taste, it may be adjusted to a few seconds, a minute, or even longer. If you use the fingerprint sensor to turn on the display without first locking it, it will not function.
You may adjust the secured lock time so that your phone responds to your touch every time by using the techniques listed below.
Method 2: Determine whether or not the physical fingerprint hardware is operational.
Before you get into a frenzy trying to replace your phone or adjust the settings, be sure the hardware element of the device is operational. If the fingerprint sensor has been damaged during the transfer or has any default problems as a result of quality control not being able to locate it, it must be replaced.
Use your fingerprint to unlock applications using Samsung Pay or to get access to an app like LastPass that needs fingerprint verification. It will function perfectly if there are no issues with the hardware. You may attempt to unlock your phone using it once again. If it doesn’t, the issue is with the software, and you can either fiddle with the settings or wait for Samsung to provide an update.
Method 3: Reset Your Galaxy S9’s Fingerprint Button
The technique works on both the Samsung Galaxy S9 and Galaxy S9 Plus. It may seem complex, which is why we have broken down the whole procedure into simple stages that you can follow. Instead of attempting to comprehend everything at once, take it one step at a time and follow the directions, and you’ll be well on your way to making your button function properly.
- On your Samsung Galaxy S9 smartphone, go to the Settings menu.
- Scroll down to the Lock Screen and Security option.
- It’s likely that you stored up to five fingerprints in it so that you could quickly unlock your smartphone.
- Make certain that you remove them all without leaving a trace.
- Restart your phone once it has been removed. You may do so by pressing and holding the power button for a few seconds before selecting the restart option.
Developing New Signatures
- The sensor may not recognize when you press it if the fingerprints previously saved on your device are corrupted or the files are inaccessible.
- Make a whole new set of fingerprints.
- Set up Fingerprints by going to Settings, Lock Screen, and Security.
- You may also reach the service menu by dialing *#0*# on your smartphone dialer.
- Select Sensors, followed by Fingerprint.
- To solve the problem, choose Normal and restart your device.
Disable Active Fingerprint Gestures (method 4)
While fingerprint gestures may not directly impact the sensor or its responsiveness, they may cause problems on your Galaxy S9 Plus. The other alternative is to turn it off completely and check whether your phone reacts to your touch as it should.
- Open your smartphone’s Settings app.
- Find the Advanced Features option by scrolling down.
- Continue scrolling until you reach the Finger Sensor Gestures page, where you may turn off the function.
- Restart your phone once you’ve successfully disabled it.

Method 5: Manually configure your fingerprint sensor
Samsung does offer some pointers for newcomers to help them get the swing of utilizing their technology and solve issues as they occur. If the fingerprint scanner on your Galaxy S9 isn’t functioning, you may try the manual approach, which is one of the most reliable. While it is not a major update, it did allow many Galaxy owners to utilize the fingerprint sensor again, which is why you should try it.
Samsung advised you not to continuously pressing the sensor to have it capture your print during the initial setup of your phone. Instead, swipe your finger over the back button, and it will be detected without trouble. It doesn’t make much sense in general, but it works technically, which is why the business recommended it in the first place. You should attempt the other option right now.
- Open your Settings option, head to Lock Screen & Security.
- Make a point of deleting all of the fingerprints you’ve already stored on your phone.
- Samsung will instruct you to swipe rather than touch your finger.
- Don’t listen to them and hold your finger firmly on the sensor button until your prints are captured.
- Continue doing so until all of your fingerprints have been saved.
- Make careful to spin your finger in all directions to ensure that the corners of the phone are properly registered.
Restart your phone once you’ve completed the procedure. Check to see whether your fingerprint sensor is working properly; if it is, your difficulties will be resolved even before Samsung releases software upgrades. Furthermore, not every device will be repaired since, in many instances, the issue is with the device, how it is configured, and how the user slides their finger over the sensor.
Get Rid of Physical Issues (Method 6)
Many consumers immediately point the blame onto the manufacturer, the hardware, or the phone’s operating system. A large debate on the Samsung site on Reddit revealed that the latest version of their phone is just amazing. Users claim that the Samsung Galaxy S9 and S9 Plus are much better at immediately detecting a finger than prior phones such as the Galaxy S8 or even the older Galaxy S6. Even if you do it incorrect the first time, it never takes more than two attempts.
When individuals use their phones, they are more likely to have physical problems. They often attempt to unlock with a wet finger, food items, or oil smeared on their fingertips, which results in such problems. To unlock your smartphone safely, make it a practice to clean your thumb, forefinger, or whichever finger you have registered as the main one.
According to reviews and users on Reddit forums, the phone’s sensor is the quickest and most accurate of all. The product’s build quality was exposed after a thorough disassembly, and Samsung continues to improve it with software upgrades. Even yet, if the issue is with your physical self, you will not be able to solve it until you take the required steps.

- To reset your phone, press and hold the power, volume up, and Bixby buttons at the same time.
- Wipe the cache memory, erasing anything previously saved.
- It’s a lot better, particularly if your phone has just had a software update and you’re having problems with fingerprint recognition.
- Reset your fingerprint and attempt unlocking it.
- You may also let the phone a day or two to adapt to your routine.
- If it still doesn’t function, take it to a Samsung Galaxy service facility to get it fixed or replaced as needed.
