How To Improve Fingerprint Accuracy On Your Phone

Fingerprint sensors on smartphones have significantly evolved from the early days when capacitive sensors were standard. Nowadays, many smartphones feature under-display fingerprint readers. These advanced sensors, particularly the optical variants, can sometimes experience issues with accuracy. If you're looking to improve the precision of your phone's fingerprint sensor, this guide will offer the key steps to achieve that.

Improve Fingerprint Accuracy on Your Phone Using a Number of Methods

Now, if you are looking to improve fingerprint accuracy on your phone, the process is simple, but you need to know that this is not a one-size-fits-all approach. It might work for your phone, or it might not, depending on how severely inaccurate your phone's fingerprint scanner is. Still, I will mention a number of methods that you can try, and that should help you gain a little boost in overall functionality.

Re-Enroll Your Fingerprint

The first step you should take is to re-enroll your fingerprint. Here’s how you can do it:

1. Go to Settings on your device.
2. Look for the place that allows you to register your fingerprints. On OxygenOS, it's Settings > Security and Privacy > Device Unlock > Face and Fingerprint Unlock > Fingerprint. On your device, it might vary.
3. Now, go ahead and enroll the same fingerprint again. So, if you have enrolled your left thumb, enroll your left thumb again. Do keep in mind that some devices might not let you add the same fingerprint again, so it varies from OEM to OEM. If the device allows you to enroll the same fingerprint, go ahead with it.

Ideally, this should help you improve your fingerprint accuracy, but if that does not work, I have some more tips for you below that should deliver some improvement.

Make Sure the Sensor Area is Clean

A common cause of fingerprint recognition problems is a dirty sensor. Ensuring the sensor area is clean is crucial. Dust, oils from your skin, or other debris can prevent the sensor from accurately reading your fingerprint. Regularly cleaning the sensor with a soft, dry cloth can help keep it free from any contaminants.

Replace Your Screen Protector

Screen protectors can sometimes interfere with the fingerprint sensor, especially if the protector is thick or not designed to work with fingerprint sensors. If you are using a screen protector, consider replacing it with one that is specifically designed for fingerprint sensors. There are many high-quality screen protectors available that are thin and maintain full functionality of the fingerprint sensor.

Re-Add Your Fingerprint Sensor

Sometimes, simply re-adding your fingerprint can solve the problem. Delete the existing fingerprint data from your device and add a new fingerprint. This can help if the original scan was not perfect or if your fingerprint has changed slightly over time due to wear and tear on your skin.

Cover the Entire Fingerprint Sensor

When using the fingerprint sensor, make sure to cover the entire sensor with your finger. If you only partially cover the sensor, it may not be able to read your fingerprint accurately. This is especially important for under-display sensors that require a more precise placement of your finger.

Update Your Phone's Software

Another approach you can take is to ensure your phone's software is updated, as manufacturers frequently release updates that enhance fingerprint sensor accuracy. These updates typically include various performance improvements and bug fixes for hardware components like fingerprint readers. Keeping your phone's software current can help you benefit from these enhancements.

Consult a Professional Technician

If you've exhausted all other troubleshooting methods and your fingerprint sensor still isn't working, it may be time to seek help from a professional technician. There could be a deeper hardware issue at play that needs expert attention. A technician can diagnose the problem accurately and recommend the necessary repairs or replacements.

Conclusion

To enhance the accuracy of your phone's fingerprint sensor, consider a mix of software and hardware adjustments. Start by re-enrolling your fingerprint and keeping the sensor clean. It's also crucial to use a screen protector that's compatible with your device. Re-add your fingerprints and ensure you're placing your finger correctly on the sensor. Additionally, make sure your phone's software is up to date. If these steps don't resolve the issue, it might be time to consult a professional technician to check for any hardware problems. By taking these measures, you can improve the reliability and precision of your fingerprint sensor.
