Finally on par with competing products, it is reported that Google Pixel 9 series mobile phones will use ultrasonic under-screen fingerprint recognition

July 4 news, Google Pixel series mobile phones have had some troublesome problems in the past few generations, such as the use of outdated camera sensors, lack of ultra-wide-angle lenses, non-equal-width screen borders on all four sides, and extremely slow charging speeds wait.

Fortunately, Google has solved the above problems, and the upcoming Pixel 9 series will also make improvements to the long-term pain points of Pixel phones - the unlocking speed is slightly slow and sometimes unreliable Reliable under-screen fingerprint recognition.

However, there are problems with the fingerprint unlocking speed and scanning reliability of Pixel 6. Although subsequent system updates and the next generation of Pixel phones have improved the situation to a certain extent, the unlocking speed is still slower than competing models, and this A problem that continues to this day.

Optical scanners typically unlock more slowly, are less accurate, and are more sensitive to any water spots or smudges on your fingers. Additionally, there are issues when using it in low-light environments, as optical scanners require the screen to flash in the scanner's position, meaning users may have the flash in their eyes if the circles on the screen are not completely covered.

The specific model used is Qualcomm's 3D Sonic Gen 2 (QFS4008), which is the exact same model used in the Samsung Galaxy S24 Ultra. While the overall unlocking experience and speed depends on more than just the hardware, ultrasonic sensors are definitely better than optical sensors.

The new ultrasonic fingerprint recognition sensor will be applied to all Pixel 9 models, except for the folding screen Pixel Fold, which will continue to use the fingerprint recognition solution in the power button.
