Samsung Galaxy S23 Ultra to use ultrasonic fingerprint sensor, protective glass leaked as well

Samsung reportedly started the One UI 5.1 firmware development for its upcoming flagship smartphone lineup that may be released in February next year. Ahead of launch, it’s reported that the Galaxy S23 Ultra still uses the ultrasonic fingerprint sensor, similar to the S22, and protective glass leaked as well.

As claimed by tipster IceUniverse, the Galaxy S23 Ultra could feature an ultrasonic fingerprint sensor. Moreover, the protective glass suggests that the fingerprint sensor’s position could be the same as the Galaxy S22 Ultra smartphone.

Compared to the previous Galaxy S flagships, the Galaxy S22 Ultra is equipped with an upgraded fingerprint sensor that significantly reduces the delay of recognition. Albeit, it still remains a mystery whether the Galaxy S23 Ultra will use Qualcomm’s 3D Sonic Max or not.

A few months back, it was rumored that the South Korean phone maker will use Qualcomm’s 3D Sonic Max fingerprint sensor for the Galaxy S23 Ultra flagship. Notably, it’s not going to happen for the first time as the same sensor already debuted with vivo X80 Pro.

The new Qualcomm 3D Sonic Max sensor’s reading area is over 4x (20x30mm2) than the 3D Sonic Gen 2. This large fingerprint sensing area could make it easy to unlock the Galaxy S23 Ultra to provide users with quicker unlocking experiences.
