Here’s How to Make a Fingerprint Scanner Fast on Samsung Phones

In recent years, Samsung has introduced in-display fingerprint scanners on their flagship and upper mid-range devices. These scanners provide a convenient and secure way to unlock your phone. However, there can be a noticeable difference in speed between in-display fingerprint scanners and capacitive fingerprint scanners. If you’re looking to improve the speed of your Samsung Galaxy fingerprint scanner, this comprehensive guide is for you.

Fingerprint Scanners on Samsung Devices

Before we dive into the tips and tricks, let’s briefly understand the different types of fingerprint scanners used in Samsung devices. The flagship Galaxy S series and Note series use ultrasonic fingerprint scanners, while the upper mid-range A series devices use optical in-display fingerprint scanners. While both technologies offer secure biometric authentication, there is a difference in their speed and accuracy.

Tip #1: Scan the Same Finger Multiple Times

One effective way to improve the speed and accuracy of your fingerprint scanner is by scanning the same finger multiple times. Samsung allows users to register up to four fingerprints on their devices. Instead of registering four different fingers, try registering the same finger multiple times. This simple trick can make a significant difference in the performance of your fingerprint scanner.

To register the same finger multiple times, follow these steps:

1. Open the Settings app on your Samsung Galaxy device.
2. Navigate to the Biometrics and security section and tap on it.
3. Choose Fingerprints from the menu.
4. If prompted, enter your PIN or pattern to proceed.
5. Tap on the option to add a fingerprint.
6. When prompted to scan your fingerprint, scan the same finger multiple times.
7. Repeat the scanning process for the same finger at least twice.
8. Once you have registered the fingerprint multiple times, lock your device and test the fingerprint scanner’s speed and accuracy.

By registering the same finger multiple times, you are providing the fingerprint scanner with more data points, enhancing its ability to recognize your fingerprint quickly and accurately.

Tip #2: Utilize Smart Lock to Skip Fingerprint Reading

Smart Lock is a convenient feature that allows you to bypass the fingerprint lock screen when your phone is in a trusted environment, such as your home or pocket. By enabling Smart Lock, you can save time by skipping the fingerprint reading process when it’s not necessary.

To set up Smart Lock and skip the fingerprint lock screen, follow these steps:

1. Open the Settings app on your Samsung Galaxy device.
2. Go to the Lock screen and security section.
3. Select Secure lock settings and tap on Smart Lock.
4. From the Smart Lock menu, choose the trusted environments where you want to skip the fingerprint lock screen.
5. Follow the on-screen instructions to set up the trusted environments.

Once you have set up Smart Lock, your device will automatically bypass the fingerprint lock screen when it detects that it’s in a trusted environment. This feature can significantly improve the speed and convenience of unlocking your Samsung Galaxy device.

Tip #3: Keep Your Phone Clean

One common issue that can affect the accuracy and speed of a fingerprint scanner is dirt and smudges on the scanner itself. It’s essential to keep your phone clean, particularly the area around the fingerprint scanner, to ensure optimal performance.

Here are some tips to keep your phone and fingerprint scanner clean:

1. Regularly wipe the screen and fingerprint scanner with a microfiber cloth to remove fingerprints, smudges, and dirt.
2. Avoid touching the fingerprint scanner with dirty or greasy fingers.
3. Use a screen protector to protect the fingerprint scanner from scratches and dirt buildup.
4. If necessary, gently clean the fingerprint scanner with a small amount of isopropyl alcohol and a soft cloth.

By keeping your phone and fingerprint scanner clean, you can maintain the accuracy and speed of the scanner, ensuring a seamless unlocking experience.

Additional Tips and Considerations

While the tips mentioned above can significantly improve the speed of your Samsung Galaxy fingerprint scanner, there are a few additional factors to keep in mind:

1. Software Updates: Regularly check for software updates on your Samsung device. These updates often contain improvements and optimizations for the fingerprint scanner, enhancing its performance.
2. Proper Finger Placement: When using the fingerprint scanner, ensure that you place your finger correctly on the scanner. Follow the on-screen instructions and make sure your finger covers the entire scanner area.
3. Avoid Moisture: Moisture can interfere with the accuracy of the fingerprint scanner. Ensure that your fingers and the fingerprint scanner are dry before attempting to unlock your device.
4. Test Different Fingers: If you’re experiencing issues with a specific finger, try registering and using a different finger to see if it improves the speed and accuracy of the fingerprint scanner.

Remember, while these tips can enhance the speed of your Samsung Galaxy fingerprint scanner, individual experiences may vary. If you continue to experience issues with your fingerprint scanner, consider reaching out to Samsung support for further assistance.

Conclusion

In conclusion, by following these tips and keeping your Samsung Galaxy device clean, you can significantly improve the speed and accuracy of your fingerprint scanner. Whether you’re using an ultrasonic or optical in-display scanner, these simple techniques can enhance your unlocking experience and provide you with a more seamless and efficient way to access your device.
