Are there any third-party apps that can enhance the fingerprint reader on the OnePlus 12

However, there are a few things you can do to improve the fingerprint reader's performance on the OnePlus 12:

Enroll Your Fingerprint Properly

- Go to Settings > Security & Privacy > Fingerprint
- Enroll your fingerprint by placing your finger on the sensor repeatedly until it reaches 100%
- Try enrolling different parts of your finger for better recognition

Use a Certified Screen Protector

- OnePlus recommends using a certified screen protector or no screen protector at all for optimal fingerprint recognition[8]
- Third-party screen protectors, especially tempered glass ones, may affect fingerprint sensor performance[2]

Enable Fingerprint Unlock in Other Apps

- Go to Settings > Security & Privacy > Fingerprint
- Tap the three-dot menu and go to Settings
- Enable Other unlock methods
- This allows you to use your fingerprint to unlock supported third-party apps[3]

Reboot and Restart Authentication

- If the fingerprint reader is not working in third-party apps, try rebooting your phone
- Go to Settings > Security & Privacy > Fingerprint
- Deactivate and reactivate the Other unlock methods option
- This may resolve any temporary glitches[3]

While there are no dedicated third-party apps to enhance the fingerprint sensor, following these tips should help optimize its performance on your OnePlus 12. The fingerprint reader is a built-in feature, so its core functionality is limited to what OnePlus provides in their software.
