• Pixel 9 and 9 Pro rumored to use Qualcomm’s 3D Sonic Gen 2 sensor.
• Ultrasonic sensors offer better performance in wet conditions.
• Larger sensor area ensures easier finger placement and more data capture.
• Pixel 9 Pro Fold to retain side-mounted fingerprint sensor.

Google’s upcoming Pixel 9 and 9 Pro might feature a significant upgrade in their unlocking mechanism.

As you might know, currently the Pixel lineup relies on optical in-display fingerprint authentication in addition to facial unlock.

Now, according to a recent report by Android Authority, these devices are rumored to incorporate an ultrasonic fingerprint sensor, marking a departure from the optical sensors used in previous models.

Ultrasonic Technology

The Pixel 9 and 9 Pro are expected to use Qualcomm’s 3D Sonic Gen 2 sensor.

This technology uses inaudible sound waves to create a detailed 3D image of a fingerprint’s ridges and valleys.

The sensor, measuring 8x8mm, offers a larger surface area compared to its predecessor, allowing for easier finger placement and capturing more biometric data.

Ultrasonic sensors are known for their improved performance, especially in challenging conditions.

They are reportedly faster than optical sensors when fingers are wet, addressing a common user complaint.

Since the Pixel 6, Google has used under-display optical fingerprint sensors.

While performance has improved over time, many users still prefer the reliability of earlier Pixel models with rear-mounted sensors.

Optical vs Ultrasonic vs Face Unlock

Optical sensors work by shining light on the finger and capturing an image.

In contrast, ultrasonic technology creates a 3D map of the fingerprint, potentially offering better security and performance.

Interestingly, the rumored Pixel 9 Pro Fold is expected to retain a side-mounted fingerprint sensor integrated into the power button.

The Pixel 8 introduced universal face unlock, which has been well-received.

However, its camera-based implementation can struggle in low light, making a reliable fingerprint sensor still essential.

If true, this move would align Google with other manufacturers like Samsung, who have been using ultrasonic sensors in their flagship devices for several years.

As with all rumors, this information should be taken with caution until officially confirmed by Google.
