Vivo has been the industry pioneer of In-Display Fingerprint Scanning Technology from showcasing its first prototype demonstration to successful mass production. To ensure user expectations for this technology are being met, Vivo has tasked its teams to innovate and perfect this technology on the new X21 to provide a reliable and secure unlocking solution to all consumers. Vivo X21 replaces the rear fingerprint sensor with the latest In-Display Fingerprint Scanning Technology. This allows the sleek and unified design of the smartphone to be preserved without the need for a rear fingerprint sensor. With just a flick of the wrist and a press on the screen to unlock, this convenient and seamless process is intuitive for any user. Other than In-Display Fingerprint Scanning Technology, X21 also offers upgraded facial recognition technology with Face Access which scans users’ facial features for enhanced security.
