From bulky physical button sensors, and capacitive ones, to under-display optical fingerprint sensors and ultrasonic ones, the technology has significantly advanced over the last decade, with ultrasonic sensors sitting at the pinnacle at the moment.
They truly shine when it comes to accuracy, considering that their ultrasonic pulses can penetrate through surface or finger contaminants like dirt, oil, or moisture. We’ve previously only seen ultrasonic fingerprint scanners on Samsung’s flagship devices, and most recently, the Pixel 9 series. Ultrasonic fingerprint scanners have long had one major drawback — they’re expensive, essentially preventing them from making their way to a wider range of devices.
OnePlus recently confirmed in a Weibo post that its upcoming OnePlus 13 flagship will be unveiled on October 31 in China.
