Hey Questers, 

Are you facing issues with the Ultrasonic Fingerprint Sensor on your iQOO 13? Is your fingerprint sensor not working smoothly after applying a tempered glass screen protector? Let's break down the issue and guide you to the perfect solution.

Here's what you need to know:

Understanding the Ultrasonic Fingerprint Sensor

The iQOO 13 comes equipped with an ultrasonic fingerprint sensor, a cutting-edge technology that:

• Uses ultrasonic waves to penetrate the display and detect your fingerprint pattern.
• Offers enhanced security and a seamless locking/unlocking experience.

However, for this technology to work effectively, the material and thickness of any screen protector applied to the display are crucial.

The Issue with Third-Party Tempered Glass

Applying third-party tempered glass screen protectors can:

• Interfere with the transmission of ultrasonic waves.
• Lead to slower response time or prevent the sensor from working entirely.

After investigation, our engineers found that most issues stem from the thickness and composition of third-party tempered glass, which aren't optimised for the iQOO 13's ultrasonic fingerprint sensor.

Why the Official Screen Protector is Better

The iQOO 13 is pre-installed with a high-quality official screen protector, designed specifically for your device. Here's why it's superior:

1. Thin and Flexible Material: Allows ultrasonic waves to pass through with minimal signal loss.
2. Device Compatibility: Professionally tuned for the iQOO 13 to ensure seamless performance.
3. Rigorous Testing: Undergoes four rounds of quality assurance for durability, stain resistance, and responsiveness. 

On the other hand, third-party tempered glass:

• May not provide significant protection against drops.
• Can disrupt fingerprint scanning functionality.

Fun Fact: The iQOO 13's Schott Xensation Alpha glass already offers excellent durability, reducing the need for additional tempered glass.

What You Should Do

To ensure the best experience with your iQOO 13:

1. Stick to the pre-installed official screen protector or replace it with an official alternative.
2. Avoid using third-party tempered glass protectors, as they can interfere with the fingerprint sensor.
3. If you've already applied third-party tempered glass and are experiencing issues, consider removing it and switching to the official protector.

Key Takeaway

For a smooth, secure, and hassle-free experience, trust the official protective film designed for the iQOO 13. It ensures your ultrasonic fingerprint sensor works flawlessly while providing the durability you need.
