Perfect Fingerprint Integration： Screen Protector Installation and Fingerprint Recognition Guide.​
1、Ensure the phone film aligns with the edge of the fingerprint sensor.​
2、Use a scraper to push out any bubbles inside the fingerprint sensor.​
3、Clean any possible dust on the film with a dry cloth.​
4、After installation, wake up your device, go to Settings ——Search —— Fingerprint, and re-register the fingerprints. (Pay attention to the film's edge when registering fingerprints to ensure accurate recognition by the sensor.)​
5、After resetting, test your phone's unlock function several times using the newly registered fingerprint until it operates smoothly​
If the fingerprint recognition fails, try adjusting your finger position or ensuring that both your finger and the sensor are clean and dry. You may also need to re-register the fingerprint in your phone's settings for better accuracy.
