Optical under-screen fingerprint is currently the most common fingerprint scheme, which is fast, sensitive, and has good recognition accuracy, and is adopted by the majority of mobile phone manufacturers. OnePlus and Xiaomi are widely using optical fingerprints, but according to channel sources, the next generation of OnePlus 13 and Xiaomi 15 series will use more advanced and secure ultrasonic fingerprints.
Compared with optical fingerprints, ultrasonic fingerprints can restore the three-dimensional effect of fingerprints at the 3D level, which cannot be broken by fingerfilms, and is higher than optical fingerprints in terms of security. At the same time, ultrasonic fingerprints can also be used when hands are wet, and the recognition area is much larger than optical fingerprints, fingerprint entry is fast, and it is more convenient to use fingerprints to unlock.
It is reported that Xiaomi is testing an ultrasonic fingerprint sensor, which is expected to be used in the Xiaomi 15 series, which will be released at the end of the year. The OnePlus 13 is also ready to move to ultrasonic fingerprints.
Previously, Samsung and vivo were frequent customers of ultrasonic fingerprint solutions, Samsung has been using ultrasonic fingerprints since the beginning of the Galaxy S10 series, and vivo is widely equipped with large-area ultrasonic fingerprint solutions in the high-end models of the X series.
Ultrasonic fingerprinting has obvious advantages over optical fingerprinting, but the disadvantage is that the cost is higher. Fortunately, for top-of-the-line flagships like the Xiaomi 15 and OnePlus 13, these costs can still be eaten.
