Google is finally upgrading the fingerprint reader on the Pixel lineup to ultrasonic technology, a move that is sure to improve the speed and accuracy of unlocking the device. The upgrade to Qualcomm's 3D Sonic Gen 2 reader, also used in the Galaxy S24 Ultra, promises a faster and more reliable unlocking experience. This new technology will eliminate the need to cover the optical reader entirely with your finger, solving a common issue with current fingerprint readers. The Pixel 9 and Pixel 9 Pro are expected to feature this upgraded sensor, while the Fold model will retain its scanner embedded in the power button. Overall, this upgrade is expected to greatly enhance the user experience for Pixel users and will likely be well-received by those who have been waiting for this improvement.
