How to Fix OnePlus 15 Fingerprint Sensor Not Working

Troubleshooting Fingerprint Recognition Issues

• 💡 Clean the fingerprint sensor area and the device screen using a microfiber cloth or a dry towel to ensure a smooth surface.
• ⚠️ If cleaning doesn't help, remove or replace the screen protector, as third-party protectors are a common cause of recognition problems.
• 📌 It's recommended to use the original OnePlus screen protector for best compatibility with the fingerprint scanner.

Re-registering Fingerprints for Accuracy

• 🎯 Remove any previously added fingerprints from the device before adding new ones.
• 👆 When adding a new fingerprint, press and hold on the scanner area, ensuring you capture the edges of your fingerprint as prompted by the on-screen guide.

Software and System Checks

• 💻 Navigate to Settings → System & Update → Software Update to check for and install the latest firmware for your OnePlus 15.
• 🔄 If no software updates are available, manually restart your phone by pressing the power button and volume up key simultaneously.

Testing the Fix

• 🔑 After a restart or update, re-enter your password to unlock the device before testing the fingerprint scanner.
• ✅ The fingerprint scanner should now work smoothly after applying these steps, with successful recognition demonstrated.
• 🤔 If issues persist, the screen protector is the most likely culprit interfering with the scanner.
