The upcoming Google Pixel 9 lineup is set to revolutionize the smartphone industry with the introduction of a faster and more reliable ultrasonic fingerprint scanner. According to reports from Android Authority, this new technology will replace the optical under-display fingerprint sensor that was featured on the Pixel 6. This shift towards ultrasonic technology is aimed at overcoming the limitations of traditional optical scanners.
Optical fingerprint scanners have been a common method for reading fingerprints, but they come with their own set of challenges. These scanners rely on flashing light against the user’s finger to visually detect patterns and ridges on the surface. However, this method is susceptible to interference from dirt, blemishes, and even variations in light levels and finger dryness. As a result, some users have reported issues with the reliability of optical scanners when trying to unlock their devices.
In contrast, ultrasonic sensors offer a more accurate and reliable way of reading fingerprints. By bouncing ultrasonic pulses off the user’s finger, these sensors are able to create a detailed 3D map of the fingerprint, making them less prone to interference from external factors. This means that users can unlock their devices with greater ease, even in challenging conditions such as wet or oily fingers. Additionally, ultrasonic sensors are more user-friendly as they do not rely on visible light and can be used in low-light settings without blinding the user.
The Pixel 9 lineup is expected to feature Qualcomm’s 3D Sonic Gen 2 (QFS4008) ultrasonic fingerprint scanner, the same model found on the Samsung Galaxy S24 Ultra. This cutting-edge technology is set to be available on all Pixel 9 models, except for the Fold 2 which will retain its current power button-based fingerprint sensor. As the launch event for the Pixel 9 approaches on August 13th, consumers can look forward to experiencing the benefits of this advanced fingerprint scanning technology.
The shift towards ultrasonic fingerprint scanners in the Google Pixel 9 lineup represents a significant advancement in smartphone security and user experience. By adopting this state-of-the-art technology, Google is addressing the limitations of traditional optical scanners and providing users with a more reliable and user-friendly way of unlocking their devices. As the smartphone industry continues to evolve, it is innovations like these that will shape the future of mobile technology.
