There have been issues with Google Pixels throughout several generations, including some fundamental issues. Older camera sensors, lack of ultrawide cameras, uneven bezels, and slow charging are just a few examples.
It is a relief to know that Google eventually addressed all of those examples. Pixel 9 series promises to fix another long-standing Pixel problem – the slightly unreliable under-display fingerprint sensor. In its upcoming devices, Google will use an ultrasonic fingerprint scanner, according to Android Authority.
Since the Pixel 6, Pixel phones have used optical fingerprint scanners that have been replaced by ultrasonic scanners. Although optical scanners are functional, they have been criticized for their slower unlock speeds, poor accuracy, and moisture sensitivity. The users are also inconvenienced by the bright flash they emit in low-light conditions.
The Pixel 9 is reportedly using the Qualcomm 3D Sonic Gen 2 ultrasonic scanner, which is known for its more reliable, faster performance. They are less likely to make errors due to their ability to create a more detailed fingerprint image. Moreover, they do not require a bright flash to operate in different lighting conditions.
Due to its unique design, the Pixel 9 Fold is not expected to feature an ultrasonic fingerprint scanner. The power button will retain the fingerprint scanner.
