OnePlus has confirmed that its upcoming 15T smartphone will feature a 3D ultrasonic in-display fingerprint sensor, upgrading the biometric authentication capability found on previous models.
The confirmation came from Li Jie Louis, president of OnePlus China, who posted details about the device on Weibo ahead of its launch later this month.
The OnePlus 15T pairs the 3D ultrasonic sensor with a 6.32-inch flat AMOLED display running at 165Hz. The device carries a 7,500mAh battery with 100W wired charging, 16GB of RAM, and runs Android 16. It holds IP66, IP68, and IP69/IP69K water and dust resistance ratings.
3D ultrasonic fingerprint sensors use sound waves to map the three-dimensional ridges of a fingerprint, rather than relying on optical imaging. The approach performs more reliably on wet fingers and is harder to spoof with flat images or casts compared to optical alternatives. Qualcomm produces a widely deployed version of this sensor technology used across flagship Android devices.
The inclusion of the technology in the 15T positions it alongside other premium Android handsets that have adopted ultrasonic sensing as a differentiator in mobile biometrics. For users who rely on in-display fingerprint unlock as their primary authentication method, the sensor type matters in terms of speed, accuracy, and resistance to false accepts.
