Igeekphone February 3 news, the blogger @digital chat station today exposed some configurations of a Snapdragon 8 Gen 4, which is expected to come from Xiaomi 15 series.
The blogger revealed that the Snapdragon 8 Gen 4 new machine is testing the domestic single point ultrasonic fingerprint unlock, and the current internal product progress is again ahead of schedule, and the straight and double size strategy remains unchanged.
It is worth mentioning that the blogger previously broke the news that the Xiaomi Snapdragon 8 Gen 4 new machine internal testing progress is good, Qualcomm this all-self-developed architecture chip performance enhancement is also a lot, straight double flagship may enter the mass production stage in September, the core configuration to complement the short board to enhance the long board. For reference, the Mi 14 series phone was released on October 26, 2023.
In addition, Xiaomi’s new machine is testing ultrasonic fingerprint unlocking, which is also worth paying attention to.
According to Igeekphone, wide area ultrasound and single point ultrasound are two ways of mobile phone ultrasonic detection, and the sending range of wide area ultrasound and single point ultrasound is different in size and sensitivity.
Wide-area ultrasound refers to the occurrence of ultrasonic waves from multiple parts, according to the reflected wavelength to complete fingerprint detection, which sends ultrasonic waves in a wide range and high sensitivity; Single-point ultrasound is a detection method that sends ultrasonic waves from one point, and the range of ultrasonic waves is only near the point where ultrasonic waves are sent.
However, whether it is wide-area ultrasound or single-point ultrasonic fingerprint unlock, it is expected to be a further step than the short-focus, optical fingerprint unlock experience.
