The fingerprint sensor on the Galaxy S24 Ultra is likely to be ultrasonic on the Pixel 9 series

Google has revealed an earlier-than-usual release date for its highly anticipated Pixel 9 series, slated for August 13. This upcoming lineup promises substantial upgrades, particularly in terms of its design philosophy. According to a recent report from Android Authority, one of the standout features of the Pixel 9 series will be its adoption of an ultrasonic fingerprint sensor, moving away from the optical sensors used in previous models like the Pixel 8 and Pixel 8 Pro. This advancement will be standard across all variants: Pixel 9, Pixel 9 Pro, and the newly introduced Pixel 9 Pro XL. In contrast, the Pixel Fold 2 is expected to integrate a capacitive fingerprint sensor within its home button.

What sets the Pixel 9 series apart is its implementation of the Qualcomm 3D Sonic Gen 2 (QFS4008) ultrasonic fingerprint sensor, similar to the one found in Samsung’s Galaxy S24 series, including the Ultra model. These ultrasonic sensors are renowned for their speed and reliability, addressing previous concerns associated with the optical sensors used in earlier Pixel models.

Since the introduction of the Pixel 6 series, Google has relied on Goodix’s optical fingerprint sensors, which, while effective for security purposes, have been critiqued for their slower responsiveness and susceptibility to inaccuracies, particularly in humid conditions. Furthermore, optical sensors have often struggled in low-light environments, necessitating adequate lighting for optimal functionality.

The shift to ultrasonic technology signifies a significant enhancement for the Pixel 9 series, promising improvements in both security and user experience. Alongside this technological leap, leaks have indicated the introduction of a new Pink color variant for the devices, as demonstrated in recent hands-on previews. Google is gearing up to unveil all three models of the Pixel 9 series next month, aiming to deliver a comprehensive range of advancements and innovations that will capture the interest of consumers worldwide.
