Google’s latest lineup of smartphones, the Pixel 9 series, is set to make a significant change in its security features by introducing a faster and more reliable ultrasonic fingerprint scanner. This new technology is said to replace the older optical under-display fingerprint sensor that was featured in the Pixel 6 models. According to reports from Android Authority, the ultrasonic scanner is capable of reading even wet or oily fingerprints, addressing some of the issues users faced with the previous technology.

The shift from optical fingerprint scanners to ultrasonic sensors marks a significant advancement in biometric security. Optical scanners, which have been around for a while, rely on visual detection of patterns and ridges on the user’s finger by flashing light against it. This method can be impacted by external factors like dirt or blemishes on the finger, leading to reliability issues, especially in varying lighting conditions. In contrast, ultrasonic sensors work by bouncing ultrasonic pulses off the fingerprints, offering greater accuracy and reliability. Moreover, users won’t have to worry about being blinded by a bright light when unlocking their phones in low-light settings.

According to leaks from reliable sources like Kamila Wojciechowska, the Pixel 9 series will be equipped with Qualcomm’s 3D Sonic Gen 2 (QFS4008) ultrasonic fingerprint scanner, the same model found in the Samsung Galaxy S24 Ultra. This collaboration suggests a commitment to delivering cutting-edge technology and security features on Google’s upcoming smartphones. While the new ultrasonic fingerprint scanner is expected to be a standard feature on all Pixel 9 models, reports indicate that the Fold 2 model may retain its current power button-based fingerprint sensor.

As we approach Google’s Pixel 9 hardware event scheduled for August 13th, anticipation is building around the new ultrasonic fingerprint scanner and its potential impact on user experience. With promises of improved accuracy, reliability, and usability, the shift to this advanced technology could set a new standard for biometric security on smartphones. Stay tuned for more updates and insights as we wait for the official unveiling of the Google Pixel 9 series.
