Google is set to unveil its new Pixel 9 series, which will feature an upgraded ultrasonic fingerprint scanner. This new technology promises to be faster and more reliable than the optical under-display sensor used in the Pixel 6, particularly in reading wet or oily fingerprints. The shift to ultrasonic sensors addresses issues related to varying light levels and finger dryness that previously impacted the accuracy of optical readers.
Optical fingerprint scanners work by illuminating the finger and capturing the reflected light to detect patterns and ridges. However, these scanners can struggle with dirt or blemishes on the finger, affecting their reliability. Ultrasonic sensors, on the other hand, utilize ultrasonic pulses to map the fingerprint. This method provides greater accuracy and performs well even in low-light conditions.
The upcoming Pixel 9 will reportedly incorporate Qualcomm’s 3D Sonic Gen 2 (QFS4008) sensor, the same model used in the Samsung Galaxy S24 Ultra. This advanced sensor is expected to significantly enhance the user experience by offering quicker and more dependable fingerprint recognition.
However, not all models in the Pixel 9 series will feature this ultrasonic scanner. The Pixel Fold 2, part of the upcoming lineup, will continue to use a fingerprint sensor integrated into the power button, rather than adopting the new under-display ultrasonic technology.
More information about the Pixel 9 series, including details on the ultrasonic fingerprint scanner, is anticipated to be disclosed during Google’s hardware event on August 13th.
