Google might fix its fingerprint scanner woes with the Pixel 9
How do optical fingerprint scanners work?
Optical fingerprint scanners work by shining a bright light over the fingerprint and capturing a digital image using a light-sensitive microchip2. The scanner analyzes the light and dark areas created by the fingerprint ridges and valleys, converting them into a digital template for identification purposes.
What will the Pixel 9 feature according to Android Authority?
The Pixel 9 will feature a faster, more reliable ultrasonic fingerprint scanner, replacing the optical under-display fingerprint sensor1. This upgrade addresses widespread issues experienced by users and provides better accuracy by using Qualcomm's 3D Sonic Gen 2 (QFS4008) technology1. The new scanner will be available on all Pixel 9 models except the Fold 2.
What technology will the Pixel 9's fingerprint scanner use?
The Pixel 9's fingerprint scanner will use ultrasonic technology, specifically Qualcomm's 3D Sonic Gen 2 (QFS4008), the same model found on the Samsung Galaxy S24 Ultra. This upgrade from optical scanners will provide significant improvements in both speed and reliability, making unlocking the Pixel 9 a breeze.
