Xiaomi is reportedly working on the Xiaomi 15 series of smartphones for the Chinese market. The Xiaomi 14 and 14 Pro debuted in October 2023 as the first smartphones equipped with the Snapdragon 8 Gen 3 chipset. The Xiaomi 15 lineup may likely debut around the same time this year. A new leak, courtesy of tipster Digital Chat Station, has revealed key information about the fingerprint scanner in the 15 series.
Xiaomi 15 series’ may feature ultrasonic in-screen fingerprint scanner
The upcoming Xiaomi 15 series may come equipped with the Snapdragon 8 Gen 4 mobile platform. The new leak by DCS suggests that the entire 15 series, which possibly includes the Xiaomi 15, 15 Pro, and 15 Ultra, is currently testing Goodix single-point ultrasonic fingerprint recognition technology. This will mark a departure from the optical fingerprint technology used in the Xiaomi 14 series.
Ultrasonic fingerprint recognition works by emitting ultrasonic waves from beneath the screen when the finger is pressed against it. These waves interact with the unique patterns of ridges and valleys on the fingerprint. By analyzing the time taken for these echoes to return and their intensity, the scanner constructs a precise 3D image of the fingerprint, allowing for accurate and secure authentication.
Ultrasonic fingerprint technology offers several advantages over optical fingerprint recognition, including better penetration, resistance to water and smudges, higher accuracy, support for detecting live fingers, and enhanced security.
DCS stated that it is still quite early to confirm the inclusion of an ultrasonic in-screen fingerprint scanner on the Xiaomi 15 series. He added that the hardware New Product Introduction (NPI) phase for the 15 series is scheduled to commence in April, at which time more concrete details may emerge.
As compared to other flagship phones, the Xiaomi 14 has a smaller display that measures 6.36 inches. The Xiaomi 15 will likely continue to be a compact flagship phone. DCS’ leak also suggests that competing brands may also launch similarly sized smartphones in China.
