How to Fix OnePlus 13 Fingerprint Scanner Not Recognizing

The in-display fingerprint sensor on the OnePlus 13 makes unlocking your phone quick and secure. But if it suddenly stops recognizing your fingerprint, it can be annoying. You might see failed attempts, slower response, or the scanner might not detect your touch at all.

This problem usually happens because of dirt on the screen, a software issue, or a misconfigured fingerprint setup. Here’s how you can fix it and get your fingerprint scanner working smoothly again.

Why Your OnePlus 13 Fingerprint Scanner Might Not Be Recognizing

• The screen protector or glass is interfering with the sensor.
• The fingerprint sensor area is dirty or smudged.
• Fingerprints were registered under different conditions (wet, oily, or worn fingers).
• Software glitches or outdated firmware.
• The sensor’s calibration was affected by recent updates.

Clean the Fingerprint Sensor Area.

Dirt, oil, or moisture can reduce the accuracy of the scanner. Cleaning it helps the sensor properly read your fingerprint pattern.

1. Wipe the display gently with a soft, lint-free cloth.
2. Make sure your fingers are clean and completely dry before using the sensor again.

Once clean, test the scanner by unlocking your phone.

Remove and Re-add Your Fingerprints.

Sometimes, stored fingerprint data becomes inaccurate over time. Removing and re-adding your fingerprints recalibrates the sensor for better accuracy.

1. Open Settings, and then tap Security & privacy.
2. Tap Fingerprint unlock, and then delete the saved fingerprints.

After deleting, tap Add fingerprint and follow the prompts to register your fingerprint again. For best results, scan the same finger from slightly different angles.

Check Screen Protector Compatibility.

Certain screen protectors can block or weaken the sensor’s reading ability. If you’re using one, it might be the reason your fingerprints aren’t detected properly.

1. Remove the screen protector temporarily.
2. Try unlocking your phone again using your fingerprint.

If it works fine without the protector, consider switching to an official OnePlus-approved screen protector.

Update Software.

System bugs can sometimes interfere with fingerprint detection. Updating your OnePlus 13 ensures all hardware components, including the sensor, work as intended.

1. Open Settings, and then tap System.
2. Tap System update, and then tap Check for updates.

If an update is available, install it and restart your device afterward.

Reset Fingerprint Scanner Settings.

If your fingerprint scanner still fails, resetting security settings can help fix configuration errors.

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

This restores the default fingerprint and face unlock configurations without deleting your personal files.

The OnePlus 13 fingerprint sensor is one of its fastest security features. Once cleaned, re-registered, and updated, it should return to working quickly and reliably again.
