For Pixel phone users, unlocking their devices can sometimes feel like a gamble. The current optical fingerprint sensor, implemented since Pixel 6, has received mixed reviews. Factors like lighting and even finger moisture can affect its reliability. But Google might be set to change that with the Pixel 9 lineup.

According to a report by Android Authority, Google is ditching the optical sensor in favor of a faster, more secure ultrasonic alternative. This new technology promises to recognize fingerprints even when wet or oily, potentially solving a major pain point for Pixel users.

Optical sensors are the traditional method of fingerprint recognition used in smartphones. They work by illuminating your finger with light and capturing an image of the ridges and valleys on its surface. Any smudges, dirt, or dryness on your finger can disrupt this process, leading to failed unlocking attempts. Additionally, the light used by optical sensors can be blinding in low-light conditions.

Ultrasonic fingerprint sensors, on the other hand, take a different approach. Instead of light, they emit ultrasonic sound waves that bounce off your fingerprint. The sensor then analyzes the returning sound waves to create a detailed map of your fingerprint’s unique features. This method is not only more resistant to environmental factors like moisture and dryness, but it also works under any lighting condition, eliminating the need for a bright flash.

Reports suggest that Google is implementing Qualcomm’s 3D Sonic Gen 2 (QFS4008) ultrasonic fingerprint sensor in the Pixel 9. This is the same sensor used in the highly-rated Samsung Galaxy S24 Ultra, known for its fast and reliable fingerprint unlocking. With this upgrade, Pixel users can expect a smoother and more consistent unlocking experience, regardless of their finger’s condition or the lighting environment.

It’s important to note that the Pixel Fold 2, rumored to be part of the Pixel 9 lineup, might retain the traditional power button-mounted fingerprint sensor. This could be due to space constraints within the folding design or Google’s desire to maintain user familiarity with the existing unlock method on foldable phones.

While these are promising leaks, we’ll have to wait for Google’s official announcement on August 13th during their Pixel 9 hardware event. This event will likely shed more light on the Pixel 9’s fingerprint sensor technology and other exciting features coming to the next generation of Pixel phones.

If the rumors hold true, the Pixel 9 could mark a significant improvement in terms of user experience, especially for those frustrated with the current fingerprint sensor. With faster, more reliable unlocking, the Pixel 9 might finally deliver a seamless experience that lives up to Google’s reputation for innovation.
