How to Fix OnePlus 13 Biometrics Not Working

Biometric security makes unlocking your OnePlus 13 quick and effortless. You can use your fingerprint or face recognition instead of typing a PIN every time. But if these features stop working, it can be inconvenient, especially when you rely on them daily.

If your biometrics are suddenly unresponsive or inconsistent, it could be due to software bugs, dirty sensors, or incorrect settings. Here’s how to fix it.

Why Your OnePlus 13 Biometrics Might Not Be Working

• Fingerprint sensor or camera lens is dirty.
• Software updates or app conflicts.
• Screen protectors interfering with the fingerprint sensor.
• Biometric data not registered correctly.
• System glitches or outdated firmware.

Clean the Fingerprint Sensor and Front Camera.

The most common reason biometrics fail is because of dirt or smudges blocking the sensor. Oils and dust can prevent proper scanning and cause repeated recognition errors.

1. Wipe the screen and front camera gently with a clean microfiber cloth.
2. Make sure your fingers are dry and free from lotion or moisture before trying again.

Once clean, test your fingerprint or face unlock to see if accuracy improves.

Re-Register Your Fingerprints and Face Data.

If the saved biometric data was poorly captured or corrupted, the device may not recognize you correctly. Deleting and re-adding your data often solves the issue.

1. Open Settings, and then tap Security & privacy.
2. Tap Fingerprint unlock or Face unlock, and then delete the existing data before adding it again.

Re-register your fingerprint by placing it in different angles for better detection. For face unlock, do it in a well-lit environment.

Remove Screen Protector or Replace It.

Some thick or low-quality screen protectors can interfere with the fingerprint sensor beneath the display. Removing it helps you confirm whether the protector is the cause.

1. Gently peel off the screen protector and clean the display.
2. Test the fingerprint unlock again to see if it recognizes your input.

If it works, consider using a thinner or official OnePlus-certified screen protector.

Update the Software.

Outdated software may cause biometric performance issues. Updating your OnePlus 13 ensures that any existing bugs are fixed and the biometric systems are optimized.

1. Open Settings, and then tap About device.
2. Tap OxygenOS, and then tap Check for updates to install the latest version.

Restart your phone after the update and test both fingerprint and face recognition.

Disable Battery Optimization for Biometrics.

Battery optimization can restrict system processes in the background, including biometric services. Disabling it keeps the feature running smoothly.

1. Open Settings, and then tap Battery.
2. Tap Battery optimization, and then look for Fingerprint and Face unlock services, and set them to Don’t optimize.

This ensures the biometric sensors remain active and responsive even in low-power modes.

Reset All Settings.

If biometrics still fail after trying everything, reset your system settings to restore default configurations. This helps fix corrupted preferences without deleting your files.

1. Open Settings, and then tap System.
2. Tap Reset options, and then tap Reset all settings.

After resetting, re-register your biometric data and test the unlock function again.

Biometric issues on the OnePlus 13 are usually temporary and easy to resolve. Cleaning the sensors, updating software, or re-registering data often restores full functionality in just a few minutes.
