Google to Adopt Ultrasonic Fingerprint Recognition in Pixel 9 Series
TapTechNews July 4th news, there have been some troublesome problems in the past several generations of Google Pixel series phones, such as using outdated camera sensors, lacking an ultra-wide-angle lens, non-four-sided equally wide screen bezels, and extremely slow charging speeds, etc.
Fortunately, Google has solved the above problems, and the upcoming Pixel 9 series will also make improvements to a long-term pain point of Pixel phones - the slightly slower and sometimes unreliable under-display fingerprint recognition. According to AndroidAuthority, sources revealed that Google plans to use ultrasonic under-display fingerprint recognition technology in its upcoming new phones.
As TapTechNews understands, Pixel 6 is the first Google model to adopt under-display fingerprint recognition. Before that, Google has always used the traditional rear fingerprint recognition module. But there are problems in the fingerprint unlock speed and scanning reliability of Pixel 6, although the subsequent system updates and the next-generation Pixel phones have improved this situation to a certain extent, the unlock speed is still slower than that of competing models, and this problem persists until now.
The cause of these problems lies in the choice of the fingerprint recognition module. Google chose the optical scanner from Goodix, while the competitors have been using ultrasonic scanners. Optical scanners usually have a slower unlock speed, lower accuracy, and are more sensitive to any water stains or dirt on the fingers. In addition, there will also be problems when used in low-light environments. The screen needs to flash at the position of the scanner, which means that if the circle on the screen is not completely covered, the user may be flashed in the eyes by the flash.
On the Pixel 9 series, Google has finally decided to switch to an ultrasonic fingerprint recognition sensor. The specific model used is Qualcomm's 3DSonic Gen2 (QFS4008), exactly the same as the model used by the Samsung Galaxy S24 Ultra. Although the overall unlock experience and speed do not only depend on the hardware, the ultrasonic sensor is definitely better than the optical sensor.
The new ultrasonic fingerprint recognition sensor will be applied to all models of the Pixel 9, except for the folding screen Pixel Fold, which will continue to use the fingerprint recognition scheme in the power button. Google has confirmed that the Pixel 9 series will be released on August 13th. Let's wait and see.
