In November, Xiaomi introduced the Xiaomi 14 and 14 Pro smartphones in China, and the 14 Ultra is expected to be launched in the Chinese market at the end of this month. While the Xiaomi 14 series has not yet entered the global market, rumors have begun to talk about the Xiaomi 15 line. A new leak has revealed some details about the type of fingerprint sensor that will be seen on Xiaomi 15 series smartphones.
Xiaomi 15 series will likely have an ultrasonic under-screen fingerprint sensor
According to a leak by Chinese informant Smart Pikachu, the Xiaomi 15 Pro and Xiaomi 15 Ultra will feature an ultrasonic in-screen fingerprint scanner. There is no clarity on whether the Xiaomi 15 will have it, suggesting that it could be equipped with an optical in-screen fingerprint sensor.
For those who don’t know, the ultrasonic option uses sound waves to create a 3D map of a user’s fingerprints, offering a higher level of accuracy and security than its optical counterpart. This technology works well in difficult conditions, such as wet or dirty fingers, as it is able to penetrate surface imperfections.
Optical sensors, on the other hand, create 2D images of fingerprints using light, making them generally faster but potentially more vulnerable to forgery. While optical sensors have made significant strides in recent years, ultrasonic sensors tend to provide more robust and reliable biometric authentication, especially in adverse environmental conditions.
The Galaxy S24 series, Find X7 Ultra, and iQOO 12 Pro are among the latest phones to feature ultrasonic in-screen fingerprint sensors, while other phones, including the Xiaomi 14 series, feature an optical version.
Recent reports have revealed that the Xiaomi 15 series will be powered by the Snapdragon 8 Gen 4 chipset. The Xiaomi 15 may feature a 6.36-inch OLED display with a 120Hz refresh rate and support for 1.5K resolution, while the 15 Pro may have a larger screen with rounded edges and 2K resolution. Mass production of the Xiaomi 15 series could begin in September this year, suggesting that its launch could take place sometime in October.
